Here we present some functions, that may ease the usage of thesched package, or serve related purposes.
make_post_request()This function facilitates the creation ofRequest objectfor a POST request.
Here is an example:
my_url<- sched::URL$new("https://httpbin.org/anything")my_request<- sched::make_post_request(my_url,body ="{\"some_key\":\"my_value\"}",mime ="application/json")TheRequest object can then be used inside an URLrequest function:
res<- sched::get_url_request_result(my_request)res$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 donotuse thescheduling system of the package. It ispresented here as a convenience.
The function takes asched::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#> status_msg:
