Question

我正在使用RESTful API与Magento 2集成。当我使用邮递员时，它就像魅力一样工作，而在C＃代码中，它返回“未经授权的401”异常。

但是，它以前在C＃代码中运行，但是突然停止了工作。

我已经尝试了所有方法，尝试（WebRequest，HTTPClient和RESTsharp）返回了相同的异常。

此外，我正在使用Fiddler 4来捕获和匹配请求，我使用了Fiddler到C＃插件来提取C＃代码，还使用了邮递员的RESTsharp代码返回了相同的异常。

远程服务器返回错误：（401）未经授权。

       //Calls request functions sequentially.
        private string MakeRequests()
        {
            HttpWebResponse response;

            if (Request_hatolna_co(out response))
            {
                //Success, possibly uses response.

                string responseText = ReadResponse(response);
                response.Close();
                return responseText;
            }
            else
            {
                //Failure, cannot use response.

Answer 1

为什么在C＃代码中设置了Postman-Token？删除它，然后尝试。

Answer 2

问题出在URL上，Magento（服务器）的管理员将其更改为[HTTPS]，而不是[HTTP]。

总结了[Postman，Insomnia或任何其他API应用程序]与C＃代码之间的区别，即C＃不处理[HTTP vs HTTPs]，而API应用程序可以处理它。

Restful API在邮递员中运行，C＃不起作用[Magento集成]
