我基本上知道如何使用HttpWebRequests,但我很新手。所以我想用Post方法提交以下标记。
authenticity_token=pkhn7pwt3QATOpOAfBERZ%2BRIJ7oBEqGFpnF0Ir4RtJg%3D&question%5Bquestion_text%5D=TEST+TEST+TEST&authenticity_token=pkhn7pwt3QATOpOAfBERZ%2BRIJ7oBEqGFpnF0Ir4RtJg%3D
它的作用是单击一个按钮并发送文本“TEST TEST TEST”,这是我点击我想要的按钮时从firebug获得的标记。

要使用Http Post Request发送一些数据,您可以尝试使用以下代码:
检查'var serverResponse'是否有服务器响应。
string targetUrl = "http://www.url.url";
var postBytes = Encoding.Default.GetBytes(@"authenticity_token=pkhn7pwt3QATOpOAfBERZ%2BRIJ7oBEqGFpnF0Ir4RtJg%3D&question%5Bquestion_text%5D=TEST+TEST+TEST&authenticity_token=pkhn7pwt3QATOpOAfBERZ%2BRIJ7oBEqGFpnF0Ir4RtJg%3D");
var httpRequest = (HttpWebRequest)WebRequest.Create(targetUrl);
httpRequest.ContentLength = postBytes.Length;
httpRequest.Method = "POST";
using (var requestStream = httpRequest.GetRequestStream())
requestStream.Write(postBytes, 0, postBytes.Length);
var httpResponse = httpRequest.GetResponse();
using (var responseStream = httpResponse.GetResponseStream())
if (responseStream != null)
using (var responseStreamReader = new StreamReader(responseStream))
{
var serverResponse = responseStreamReader.ReadToEnd();
}

又一个解决方案:
// you can get the correct encoding from your site's response headers
Encoding encoding = Encoding.UTF8;
string targetUrl = "http://example.com";
var request = (HttpWebRequest)WebRequest.Create(targetUrl);
var formData = new Dictionary<string, object>();
formData["authenticity_token"] = "pkhn7pwt3QATOpOAfBERZ+RIJ7oBEqGFpnF0Ir4RtJg=";
formData["question[question_text]"] = "TEST TEST TEST";
bool isFirstField = true;
StringBuilder query = new StringBuilder();
foreach (KeyValuePair<string, object> field in formData)
{
if (!isFirstField)
query.Append("&");
else
isFirstField= false;
query.AppendFormat("{0}={1}", field.Key, field.Value);
}
string urlEncodedQuery = Uri.EscapeDataString(query.ToString());
byte[] postData = encoding.GetBytes(urlEncodedQuery);
request.ContentLength = postData.Length;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
using (BinaryWriter bw = new BinaryWriter(request.GetRequestStream()))
bw.Write(postData);
var response = request.GetResponse() as HttpWebResponse;
// TODO: process response
