Here we present some functions, that may ease the usage of the
sched package, or serve related purposes.
make_post_request()This function facilitates the creation of Request object
for a POST request.
Here is an example:
my_url <- sched::URL$new("https://httpbin.org/anything")
my_request <- sched::make_post_request(my_url,
body = "{\"some_key\": \"my_value\"}",
mime = "application/json")The Request object can then be used inside an URL
request function:
res <- sched::get_url_request_result(my_request)
res$getContent()
#> [1] "{\n \"args\": {}, \n \"data\": \"{\\\"some_key\\\": \\\"my_value\\\"}\", \n \"files\": {}, \n \"form\": {}, \n \"headers\": {\n \"Accept\": \"application/json,multipart/*\", \n \"Content-Length\": \"24\", \n \"Content-Type\": \"application/json;charset=utf-8\", \n \"Host\": \"httpbin.org\", \n \"X-Amzn-Trace-Id\": \"Root=1-66fbf6c9-5dc0edcd6466a5822b0d48e9\"\n }, \n \"json\": {\n \"some_key\": \"my_value\"\n }, \n \"method\": \"POST\", \n \"origin\": \"195.83.222.29\", \n \"url\": \"https://httpbin.org/anything\"\n}\n"get_url_request_result()This function is a plain URL requester, that do not use the scheduling system of the package. It is presented here as a convenience.
The function takes a sched::Request object as input,
along with standard parameters like:
Here is an example of usage:
my_url <- sched::URL$new("https://httpbin.org/get")
my_request <- sched::Request$new(my_url)
sched::get_url_request_result(my_request)
#> <RequestResult>
#> Public:
#> clone: function (deep = FALSE)
#> getContent: function ()
#> getErrMsg: function ()
#> getLocation: function ()
#> getRetry: function ()
#> getRetryAfter: function ()
#> getStatus: function ()
#> initialize: function (content = NULL, retry = FALSE, err_msg = NULL, status = 0,
#> processRequestErrors: function ()
#> Private:
#> addErrMsg: function (msg)
#> content: {
#> "args": {},
#> "headers": {
#> "Accept": "*/*",
#> ...
#> err_msg: NULL
#> location: NULL
#> retry: FALSE
#> retry_after: NULL
#> status: 200
