C# 利用HttpWebRequest進行HTTPS的post請求的示例

最近一個推送信息的目標接口從http格式換成https格式,原來的請求沒法正常發送,因此修改了發送請求的方法.標紅的代碼是新加了,改了以後就能夠正常訪問(不檢測證書的)

 

public static string PostData3(string posturl, string postData, Encoding encoding)
{
Stream outstream = null;
Stream instream = null;
StreamReader sr = null;
HttpWebResponse response = null;
HttpWebRequest request = null;

byte[] data = encoding.GetBytes(postData);
// 準備請求...
try
{
// 設置參數
if (posturl.StartsWith("https", StringComparison.OrdinalIgnoreCase))
{
ServicePointManager.ServerCertificateValidationCallback =
new RemoteCertificateValidationCallback(CheckValidationResult);
request = WebRequest.Create(posturl) as HttpWebRequest;
request.ProtocolVersion = HttpVersion.Version10;
}
else {
request = WebRequest.Create(posturl) as HttpWebRequest;
}

CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.AllowAutoRedirect = true;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = data.Length;
// request.TransferEncoding = encoding.HeaderName;
outstream = request.GetRequestStream();
outstream.Write(data, 0, data.Length);
outstream.Close();
//發送請求並獲取相應迴應數據
response = request.GetResponse() as HttpWebResponse;
//直到request.GetResponse()程序纔開始向目標網頁發送Post請求
instream = response.GetResponseStream();
sr = new StreamReader(instream, encoding);
//返回結果網頁（html）代碼
string content = sr.ReadToEnd();
string err = string.Empty;
return content;
}
catch (Exception ex)
{
string err = ex.Message;
LogHelper.Error("Post第三方地址" + posturl, ex);
return string.Empty;
}
}

 

private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
}
