呼叫在邮递员中有效，但在C＃中无效 [英] Call works in Postman but not in C#

问题描述

我正在尝试调用下面的URL，它在浏览器（Chrome）和Postman中都可以正常工作，但是由于某些原因，它在C＃中不起作用。

在浏览器中工作：

PS如果我删除用户代理，它仍然不起作用。为什么我在这里做错了？

解决方案

感谢Joshua& Vhoang！

在我将代码更改为以下代码后，它可以正常工作：

  var client = new RestClient（ http://presta.craftingcrow.com/api/categories）; 
 var request = new RestRequest（Method.GET）; 
 request.AddHeader（ cache-control， no-cache）; 
 request.AddHeader（ Authorization， Basic + Convert.ToBase64String（Encoding.Default.GetBytes（ AJWKBLWT47VR26QWPNFCPJLXC6217F6F：））; 
 IRestResponse response = client.Execute（request）; 
  

无需添加用户代理或在主机名（URL）中包含密钥

I am trying to make a call to below URL and it works just fine in Browser (Chrome) and also in Postman, but for some reason, it doesn't work in C#.

Working in browser:
http://[e-mail]/api/categories

Working in Postman:
http://[e-mail]/api/categories

Not working in C# (RestSharp):

var client = new RestClient("http://[e-mail]/api/categories"); 
var request = new RestRequest(Method.GET);
request.AddHeader("cache-control", "no-cache");
request.AddHeader("User-Agent", @"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36");
IRestResponse response = client.Execute(request);

Response: 401 Unauthorized

P.S. If I remove User-Agent it still doesn't work. Why am I doing wrong here?

解决方案

Thanks to Joshua & Vhoang!

It's working after I changed code to below:

var client = new RestClient("http://presta.craftingcrow.com/api/categories"); 
var request = new RestRequest(Method.GET);
request.AddHeader("cache-control", "no-cache");
request.AddHeader("Authorization", "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("AJWKBLWT47VR26QWPNFCPJLXC6217F6F:"));
IRestResponse response = client.Execute(request);

There was no need to add user-agent or include key in the hostname (URL)
