c# - RestSharp 不支持 RestRequest 请求。凭据 - 无法通过 http 代理

Question

使用下面的简单代码，RestClient 无法通过网络代理。它不尊重 request.Credentials 的值(value)

我能够访问我试图在浏览器中查询的站点；但是 RestClient 被我公司的代理阻止了。

try
{
    RestClient client = new RestClient("http://services.groupkt.com/country/get/all");
    RestRequest request = new RestRequest(Method.POST);
    
    //set credentials to default
    request.Credentials = System.Net.CredentialCache.DefaultCredentials;

    //also tried using client.UserAgent to spoof Firefox user-agent to no avail

    request.AddHeader("cache-control", "no-cache");
    request.AddHeader("content-type", "application/x-www-form-urlencoded");
    
    IRestResponse response = client.Execute(request);
    textBox1.Text = response.Content;
}
catch (Exception ex)
{
    textBox1.Text = "ERROR:" + ex.Message;
}

所以我最终在 textBox1 中得到的是呈现为的 html:

Authorized Only

Secure Web Gateway has blocked your request because you have not beenauthorized and authorization is required.

URL:

User Name / Source: / 10.xx.xx.xx

Rule Set: Authentication with Kerberos and NTLM Fallback / Authenticate

With Kerberos (don't evaluate NTLM tokens)

IMPORTANT: when you access internet web pages you should comply with authorizations approvals according to [CompanyName] Internet Filtering.

RestSharp 104.1.0.0

换句话说，RestSharp 没有像预期的那样将默认凭据传输到 Web 代理。

Answer 1

我找到了答案:

        client.Proxy = new WebProxy(myProxyUrl);
        client.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

因此它不能像 HttpWebRequest 那样简单地从您的 Windows 设置中读取代理 url。您必须提供代理网址。
