问题 I'm trying to access LinkedIn's API using R and the httr package. When I execute the last oauth2.0_token() function, in order to gain an authorization token, I get the following error from LinkedIn: "The redirect_uri does not match the registered value" .

问题 I was running the code for months without any issues, and couple days before. GET(url="myurl", query) Today I've got an error Error in curl::curl_fetch_memory(url, handle = handle) : SSL certificate problem: certificate has expired The SSL cert on the site is active and ends in a year. Also the same GET request is working via browser.... What is the issue? 🤷‍♂️ 回答1: Try testing your server with this tool: https://www.ionos.com/tools/ssl-checker and see if it says that it is "not installed

问题 I am trying to access the highlighted response header: location text in the screenshot below using only R and its curl-based webscraping libraries. one can easily get to this point in any web browser by visiting http://www.worldvaluessurvey.org/WVSDocumentationWVL.jsp, clicking on the download for any of the data files, and filling out the agreement form. The download begins automatically in a web browser. I believe that the only way to obtain a valid cookie is with library(curlconverter)

问题 I try to download the reports available in Salesforce via the URL, e.g. http://YOURInstance.my.salesforce.com/012389u13541?export=1&enc=UTF-8&xf=csv in R.

I also tried to realize the approach suggested here: https://salesforce.stackexchange.com/questions/47414/download-a-report-using-python The

问题 It appears that a new bug has appeared in a package traits that I have been using and contributing to for a few years. It used to be that I use a query with a space character, and when the package returned a url, it would replace the space with %20 , and the query would work. So, I would like users to pass the argument as Test 1 and this used to be converted behind the scenes to Test%201 which the api was happy enough to resolve. But by the time the argument gets to the httr::handle_url

问题 When using httr::GET , in certain queries it replaces % with safe representation %25 , but in other queries it doesn't. I cannot find any rule that would make this happen. I'm using httr 1.4.1 Sample query where % is replaced (notice the error code and that URL entered is not the same as in response object returned): > httr::GET("jira.spring.io/rest/api/latest/search?jql=project=Spring%20Framework&startAt=0") Response [https://jira.spring.io/rest/api/latest/search?jql=project=Spring
