问题描述

我正在尝试调用以下 URL，它在浏览器 (Chrome) 和 Postman 中都可以正常工作，但由于某种原因，它在 C# 中不起作用.

在浏览器中工作:

附:如果我删除 User-Agent 它仍然不起作用.为什么我在这里做错了?

解决方案

感谢 Joshua &旺旺！

我将代码更改为以下代码后它正在工作:

var client = new RestClient("http://presta.craftingcrow.com/api/categories");var request = new RestRequest(Method.GET);request.AddHeader("缓存控制", "无缓存");request.AddHeader("授权", "基本" + Convert.ToBase64String(Encoding.Default.GetBytes("AJWKBLWT47VR26QWPNFCPJLXC6217F6F:"));IRestResponse 响应 = 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://AJWKBLWT47VR26QWPNFCPJLXC6217F6F@presta.craftingcrow.com/api/categories

Working in Postman:
http://AJWKBLWT47VR26QWPNFCPJLXC6217F6F@presta.craftingcrow.com/api/categories

Not working in C# (RestSharp):

var client = new RestClient("http://AJWKBLWT47VR26QWPNFCPJLXC6217F6F@presta.craftingcrow.com/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)
