otelsdk package (@atheriel, #729).req_throttle() no longer resets the token bucket when
used repeatedly with the same host (#801) and never generates negative
wait times (#820).req_perform_connection() no longer errors with
no applicable method for 'close' applied to an object of class "c('httr2_failure', 'httr2_error', 'rlang_error', 'error', 'condition')"
(#817).resps_ok() returns a logical vector indicating
which requests were successful (#807).url_modify() refactored to better retain exact
formatting of URL not modified components (#788, #794)req_perform_stream() has been soft deprecated in
favour of req_perform_connection().
Deprecated functions mutli_req_perform(),
req_stream(), with_mock() and
local_mock() have been removed.
Deprecated arguments req_perform_parallel(pool),
req_oauth_auth_code(host_name, host_ip, port), and
oauth_flow_auth_code(host_name, host_ip, port) have been
removed.
Redacted headers are no longer serialized to disk. This is important since it makes it harder to accidentally leak secrets to files on disk, but comes at a cost: you can no longer perform such requests that have been saved and reloaded (#721).
URL construction is now powered by
curl::curl_modify_url(), and hence now (correctly) escapes
the path component (#732). This means that
req_url_path() now can only affect the path component of
the URL, not the query params or fragment.
New last_request_json() and
last_response_json() to conveniently see JSON bodies
(#734).
New req_get_url(), req_get_method(),
req_get_headers(), req_body_get_type(), and
req_get_body() allow you to introspect a request object
(#718).
New resp_timing() exposes timing information about
the request measured by libcurl (@arcresu, #725).
Functions that capture interrupts (like
req_perform_parallel() and friends) are now easier to
escape if they’re called inside a loop: you can press Ctrl + C twice to
guarantee an exit (#1810).
req_perform_iterative(),
req_perform_sequential(),
req_perform_parallel(), req_perform_promise(),
and req_perform_connection() now support mocking (#651). To
mock the response from req_perform_connection() create a
response with the new StreamingBody for a body.
new_response() is now exported (#751).
req_body_json() and req_body_form()
correctly unobfuscated inputs, as documented (#754).
req_body_json_modify() can now be used on a request
with an empty body.
req_error() errors with long bodies are now
correctly wrapped (#727).
req_oauth_device() gains an
open_browser argument that lets you take control of whether
a browser is opened or the URL is printed (@plietar, #763)
req_perform_parallel() handles progress
argument consistently with other functions (#726).
req_url_query() now re-calculates n lengths when
using .multi = "explode" to avoid select/recycling issues
(@Kevanness,
#719).
All print methods now send output to stdout, not the message stream.
req_headers() more carefully checks its input types
(#707).argument 'cache' is missing error (#706, @jcheng5).req_perform_parallel() lifts many of the previous
restrictions. It supports simplified versions of
req_throttle() and req_retry(), can refresh
OAuth tokens, and checks the cache before/after each request.
(#681).HTTR2_VERBOSITY environment variable (#687).local_verbosity() matches the existing
with_verbosity() and allows for local control of verbosity
(#687).req_dry_run() and req_verbose() display
compressed correctly (#91, #656) and automatically prettify JSON bodies
(#668). You can suppress prettification with
options(httr2_pretty_json = FALSE) (#668).req_throttle() implements a new “token bucket”
algorithm that maintains average rate limits while allowing bursts of
higher request rates.aws_v4_signature() correctly processes URLs containing
query parameters (@jeffreyzuber, #645).oauth_client() and oauth_token() implement
improved print methods with bulleted lists, similar to other httr2
objects, and oauth_client() with custom auth
functions no longer produces errors (#648).req_dry_run() omits headers that would vary in tests
and can prettify JSON output.req_headers() automatically redacts
Authorization headers (#649) and correctly implements
case-insensitive modification of existing headers (#682).req_headers_redacted() now supports dynamic dots
(#647).req_oauth_auth_code() no longer adds trailing “/”
characters to properly formed redirect_uri values (@jonthegeek, #646).req_perform_connection() produces more helpful error
messages when requests fail at the networking level.req_perform_parallel(pool) now is deprecated in favour
of a new max_active argument (#681).req_user_agent() memoizes the default user agent to
improve performance, as computing version numbers is relatively slow
(300 µs).resp_link_url() once again respects the case
insensitivity for header names (@DavidRLovell, #655).resp_stream_sse() automatically retrieves the next
event when the current event contains no data, and returns data as a
single string (#650).str() correctly redacts redacted headers (#682).req_perform_stream() is superseded in favor of
req_perform_connection(), which is no longer experimental
(#625).
with_mock() and local_mock() are
defunct and will be removed in the next release.
is_online() wraps curl::has_internet(),
making it easy to tell if you’re currently online (#512).
req_headers_redacted() makes it easier to redact
sensitive headers (#561).
req_retry() implements “circuit breaking”, which
immediatelys error after multiple failures to the same server
(e.g. because the server is down) (#370).
req_url_relative() navigates to a relative URL
(#449).
resp_request() returns the request associated with a
response; this can be useful when debugging (#604).
resp_stream_is_complete() checks if data remains in
the stream (#559).
url_modify(), url_modify_query(), and
url_modify_relative() modify URLs (#464);
url_query_parse() and url_query_build() parse
and build query strings (#425).
OAuth response parsing errors now have a dedicated
httr2_oauth_parse error class that includes the original
response object (@atheriel, #596).
curl_translate() converts cookie headers to
req_cookies_set() (#431) and JSON data to
req_body_json_modify() calls (#258).
print.request() escapes {} in headers
(#586).
req_auth_aws_v4() formats the AWS Authorization
header correctly (#627).
req_retry() defaults to max_tries = 2
when nethier max_tries nor max_seconds is set.
If you want to disable retries, set max_tries = 1.
req_perform_connection() gains a
verbosity argument, which is useful for understanding
exactly how data is streamed back to you (#599).
req_perform_promise() also gains a verbosity
argument.
req_url_query() can control how spaces are encoded
with .space (#432).
resp_link_url() handles multiple Link
headers (#587).
resp_stream_sse() will warn if it recieves a partial
event.
url_parse() parses relative URLs with new
base_url argument (#449) and the uses faster and more
correct curl::curl_parse_url() (#577).
req_perform_promise() upgraded to use event-driven
async based on waiting efficiently on curl socket activity (#579).req_oauth_token_exchange() and
oauth_flow_token_exchange() functions implement the OAuth
token exchange protocol from RFC 8693 (@atheriel, #460).oauth_cache_clear() is an exported end point to
clear the OAuth cache.req_auth_aws_v4() signs request using AWS’s special
format (#562, #566).req_cache() no longer retrieves anything but
GET requests from the cache.resp_stream_aws() to retrieve AWS’s special
streaming format. With thanks to https://github.com/lifion/lifion-aws-event-stream/ for a
simple reference implementation.req_perform_parallel() and
req_perform_promise() now correctly set up the method and
body (#549).req_body_file() now works with files >64kb once more
(#524) and no longer leaks a connection if the response doesn’t complete
succesfully (#534).req_body_*() now give informative error if you attempt
to change the body type (#451).req_cache() now re-caches the response if the body is
hasn’t been modified but the headers have changed (#442). It also works
better when req_perform() sets a path (#442).req_cookie_set() allows you to set client side
cookies (#369).req_perform() no longer displays a progress bar when
sleeping during tests. You can override this behaviour by setting the
option httr2_progress.req_perform_iterative() is no longer experimental.req_perform_connection() for working with streaming
data. Unlike req_perform_stream() which uses callbacks,
req_perform_connection() returns a regular response object
with a connection as the body. Unlike req_perform_stream()
it supports req_retry() (with @jcheng5, #519).req_retry() no longer treates low-level HTTP failures
the same way as transient errors by default. You can return to the
previous behaviour with retry_on_error = TRUE.resp_body_html() and resp_body_xml() now
work when req_perform() is given a path (#448).resp_stream_bytes(),
resp_stream_lines(), and resp_stream_sse() for
streaming chunk from a connection response (#519).jwt_encode_hmac() now calls correct underlying
function jose::jwt_encode_hmac() and has correct default
size parameter value (@denskh, #508).
req_cache() now prunes cache before
checking if a given key exists, eliminating the occassional error about
reading from an invalid RDS file. It also no longer tests for existence
then later reads the cache, avoiding potential race conditions.
New req_perform_promise() creates a
promises::promise so a request can run in the background
(#501, @gergness).
req_perform_parallel() now respects error handling
in req_error().
req_body_file() now only opens a connection when the
request actually needs data. In particular, this makes it work better
with req_perform_parallel() (#487).req_cache() no longer fails if the rds
files are somehow corrupted and now defaults the debug
argument to the httr2_cache_debug option to make it easier
to debug caching buried in other people’s code (#486).req_oauth_password() now only asks for your password
once (#498).req_perform_parallel() now works correctly with
req_cache() (#447) and now works when downloading 0 byte
files (#478)req_perform_stream() no longer applies the
callback to unsuccessful responses, instead creating a
regular response. It also now sets last_request() and
last_response() (#479).req_url_query() now allows you to opt out of escaping
for multi-value parameters (#404).req_perform_stream() gains a
round = c("byte", "line") argument to control how the
stream is rounded (#437).
req_retry() gives a clearer error if
after returns the wrong type of value (#385).
req_template() now works when you have a bare
: in a template that uses “uri” style (#389).
req_timeout() now resets the value of
connecttimeout set by curl. This ensures that you can use
req_timeout() to increase the connection timeout past 10s
(#395).
url_parse() is considerably faster thanks to
performance optimisations by and discussion with @DyfanJones (#429).
local_mock() and with_mock() have been
deprecated in favour of local_mocked_responses() and
with_mocked_responses() (#301).
multi_req_perform() is deprecated in favour of
req_perform_parallel(). req_stream() is
deprecated in favour of req_perform_stream()
(#314).
oauth_flow_auth_code() deprecates
host_name and port arguments in favour of
using redirect_uri. It also deprecates host_ip
since it seems unlikely that changing this is ever useful.
oauth_flow_auth_code_listen() now takes a single
redirect_uri argument instead of separate
host_ip and port arguments. This is a breaking
change but I don’t expect anyone to call this function directly (which
was confirmed by a GitHub search) so I made the change without
deprecation.
req_body_form() and
req_body_multipart() now require data ...;
they no longer accept a single list for compatibility with the 0.1.0
API.
New req_perform_sequential() performs a known set of
requests sequentially. It has an interface similar to
req_perform_parallel() but with no limitations, and the
cost of being slower (#361).
New req_perform_iterative() performs multiple
requests, where each request is derived from the previous response
(@mgirlich,
#8).
req_perform_parallel() replaces
multi_req_perform() to match the new naming scheme (#314).
It gains a progress argument.
req_perform_iterative(),
req_perform_parallel(), and
req_perform_sequential() share a new error handling
strategy. By default, errors will be bubbled up, but you can choose an
alternative strategy with the on_error argument
(#372).
A new family of functions resps_successes(),
resps_failures(), resps_requests() and
resps_data() make it easier to work with lists of responses
(#357). Behind the scenes, these work because the request is now stored
in the response (or error) object (#357).
resp_body_json() and resp_body_xml()
now cache the parsed values so that you can use them repeatedly without
worrying about the performance cost. This supports the design
req_perform_iterative() by avoiding the need to carefully
pass around a parsed object.
A new OAuth
vignette gives many more details about how OAuth works and how to
use it with httr2 (#234), and the OAuth docs have been overhauled to
make it more clear that you should use req_oauth_*(), not
oauth_*() (#330).
If you are using an OAuth token with a refresh token, and that refresh token has expired, then httr2 will now re-run the entire flow to get you a new token (#349).
New oauth_cache_path() returns the path that httr2
uses for caching OAuth tokens. Additionally, you can now change the
cache location by setting the HTTR2_OAUTH_CACHE env var.
This is now more obvious to the user, because httr2 now informs the user
whenever a token is cached.
oauth_flow_auth_code() gains a
redirect_uri argument rather than deriving this URL
automatically from the host_name and port
(#248). It uses this argument to automatically choose which strategy to
use to get the auth code, either launching a temporary web server or,
new, allowing you to manually enter the details with the help of a
custom JS/HTML page hosted elsewhere, or by copying and pasting the URL
you’re redirected to (@fh-mthomson, #326). The temporary web
server now also respects the path component of
redirect_uri, if the API needs a specific path
(#149).
New oauth_token_cached() allows you to get an OAuth
token while still taking advantage of httr2’s caching and auto-renewal
features. For expert use only (#328).
@mgirlich is now a httr2 contributor in recognition of his many contributions.
req_cache() gains max_n,
max_size, and max_age arguments to
automatically prune the cache. By default, the cache will stay under 1
GB (#207).
New req_body_json_modify() allows you to iteratively
modify a JSON body of a request.
New req_cookie_preserve() lets you use a file to
share cookies across requests (#223).
New req_progress() adds a progress bar to long
downloads or uploads (#20).
New resp_check_content_type() to check response
content types (#190). resp_body_json() and friends give
better errors if no Content-Type header is present in the
response (#284).
New resp_has_body() returns a TRUE or
FALSE depending on whether or not the response has a body
(#205).
New resp_url(), resp_url_path(),
resp_url_queries() and resp_url_query() to
extract various part of the response url (#57).
req_url_query() gains a .multi
parameter that controls what happens when you supply multiple values in
a vector. The default will continue to error but you can use
.multi = "comma" to separate with commas,
"pipe" to separate with |, and
"explode" to generate one parameter for each value
(e.g. ?a=1&a=2) (#350).
New secret_encrypt_file() and
secret_decrypt_file() for encrypting and decrypting files
(#237).
The httr2 examples now only run on R 4.2 and later so that we can use the base pipe and lambda syntax (#345).
OAuth errors containing a url now correctly display that URL (instead of the string “uri”).
curl_translate() now uses the base pipe, and
produces escapes with single quotes or raw strings in case double quotes
can’t be used (@mgirlich, #264). It gains the argument
simplify_headers that removes some common but unimportant
headers, like Sec-Fetch-Dest or
sec-ch-ua-mobile (@mgirlich, #256). It also parses the query
components of the url (@mgirlich, #259) and works with multiline
commands from the clipboard (@mgirlich, #254).
local_mocked_responses() and
with_mocked_responses() now accept a list of responses
which will be returned in sequence. They also now correctly trigger
errors when the mocked response represents an HTTP failure
(#252).
oauth_flow_refresh() now only warns, not errors, if
the refresh_token changes, making it a little easier to use
in manual workflows (#186).
obfuscated() values now display their original call
when printed.
req_body_json() gains custom content
type argument and respects custom content-type set in
header (@mgirlich,
#189).
req_cache() now combine the headers of the new
response with the headers of the cached response. In particular, this
fixes resp_body_json/xml/html() on cached responses (@mgirlich, #277).
req_perform() now throws error with class
httr2_failure/httr2_error if the request fails, and that
error now captures the curl error as the parent. If the request
succeeds, but the response is an HTTP error, that error now also has
super class httr2_error. This means that all errors thrown
by httr2 now inherit from the httr2_error class. See new
docs in ?req_error() for more details.
req_perform()’s progress bar can be suppressed by
setting options(httr2_progress = FALSE) (#251). Progress
bars displayed while waiting for some time to pass now tell you why
they’re waiting (#206).
req_oauth_bearer_jwt() now includes the claim in the
cache key (#192).
req_oauth_device() now takes a auth_url
parameter making it usable (#331, @taerwin).
req_url_query() gains a .multi
parameter that controls what happens when you supply multiple values in
a vector. The default will continue to error but you can use
.multi = "comma" to separate with commas,
"pipe" to separate with |, and
"explode" to generate one parameter for each value
(e.g. ?a=1&a=2) (#350).
New example_url() to launch a local server, making
tests and examples more robust.
New throttle_status() to make it a little easier to
verify what’s happening with throttling.
req_oauth_refresh() now respects the
refresh_token for caching (@mgirlich, #178).
req_perform() now always sleeps before a request,
rather than after it. It also gains an error_call argument
and communicates more clearly where the error occurred (@mgirlich, #187).
req_url_path() and
req_url_path_append() can now handle NULL or
empty ... and the elements of ... can also
have length > 1 (@mgirlich, #177).
sys_sleep() (used by req_retry() and
req_throttle()) gains a progress bar (#202).
curl_translate() can now handle curl copied from
Chrome developer tools (@mgirlich, #161).
req_oauth_*() can now refresh OAuth tokens. One,
two, or even more times! (@jennybc, #166)
req_oauth_device() can now work in non-interactive
environments, as intendend (@flahn, #170)
req_oauth_refresh() and
oauth_flow_refresh() now use the envvar
HTTR2_REFRESH_TOKEN, not HTTR_REFRESH_TOKEN
(@jennybc,
#169).
req_proxy() now uses the appropriate authentication
option (@jl5000).
req_url_query() can now opt out of escaping with
I() (@boshek, #152).
Can now print responses where content type is the empty string (@mgirlich, #163).
“Wrapping APIs” is now an article, not a vignette.
req_template() now appends the path instead of
replacing it (@jchrom,
#133)
req_body_form(), req_body_multipart(),
and req_url_query() now support multiple arguments with the
same name (#97, #107).
req_body_form(), req_body_multipart(),
now match the interface of req_url_query(), taking
name-value pairs in .... Supplying a single
list() is now deprecated and will be removed in a future
version.
req_body_json() now overrides the existing JSON
body, rather than attempting to merge with the previous value (#95,
#115).
Implement req_proxy() (owenjonesuob, #77).
httr_path class renamed to httr2_path
to correctly match package name (#99).
oauth_flow_device() gains PKCE support (@flahn, #92), and the
interactive flow is a little more user friendly.
req_error() can now correct force successful HTTP
statuses to fail (#98).
req_headers() will now override
Content-Type set by req_body_*()
(#116).
req_throttle() correctly sets throttle rate (@jchrom, #101).
req_url_query() never uses scientific notation for
queries (#93).
req_perform() now respects
httr::with_verbose() (#85).
response() now defaults body to
raw(0) for consistency with real responses (#100).
req_stream() no longer throws an error for non 200
http status codes (@DMerch, #137)
Fix R CMD check failures on CRAN
