如何在C中模拟浏览器HTTP POST请求和捕获结果#

你可以看看 WebClient 班级。它允许您将数据发布到任意URL:

using (var client = new WebClient())
{
    var dataToPost = Encoding.Default.GetBytes("param1=value1&param2=value2");
    var result = client.UploadData("http://example.com", "POST", dataToPost);
    // do something with the result
}

将生成以下请求:

POST / HTTP/1.1
Host: example.com
Content-Length: 27
Expect: 100-continue
Connection: Keep-Alive

param1=value1&param2=value2
