C#/Restsharp：HTTP 错误 417 预期失败

Question

我有这个代码：

System.Net.ServicePointManager.Expect100Continue = false;

RestClient = new RestClient(baseUri);
RestClient.Proxy = new WebProxy("http://proxy.domain.tld:8888");
RestClient.Proxy.Credentials = new NetworkCredential("abc", "abc");
RestClient.CookieContainer = new System.Net.CookieContainer();

// Receive JSESSIONID
var req = new RestRequest("scs/result/resultinfo.jsp", Method.GET);
var res = RestClient.Execute(req); // This request works

// Login
req = new RestRequest("scs/result/j_security_check", Method.POST);
req.AddHeader("Content-Type", "application/x-www-form-urlencoded");

req.AddParameter("j_username", username, ParameterType.GetOrPost);
req.AddParameter("j_password", password, ParameterType.GetOrPost);

res = RestClient.Execute(req); // This request fails

POST 请求导致 HTTP 错误 417: Expectation failed, even System.Net.ServicePointManager.Expect100Continue = false

你能帮帮我吗？谢谢

将上面的 XML 代码放在我的解决方案中的每个 App.config 中很有帮助。

  <system.net>
    <settings>
      <servicePointManager expect100Continue="false" />
    </settings>
  </system.net>

我从来没有用过 RestSharp，直到我用它来完成一个新项目。

StatusCode =  ExpectationFailed

所以这是 417 期望失败错误。太糟糕了，排除故障并不那么容易。

问题是 connectionstring 在 machine.config 中丢失（项目未使用 web.config / app.config 有几件事)

为我修好。
