我想在后面的代码中制作一个帖子表单。我有一个简单的 html 帖子可以正常工作,但是当我尝试将其设为 WebRequest 时,我无法使其正常工作。

提前感谢您的时间。

这是工作>

<body>
<form action="http://www.pay-pos.com/test.php" method="post">
<textarea name="datafromuser">
<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>1058</ClientId><IPAddress>213.456.654.456</IPAddress><Adress>asdsa</Adress><OrderId>123</OrderId><Type>Auth</Type>
<Number>4522115422659661</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val><Total>10</Total><Taksit></Taksit><Kdv>18</Kdv><BankaID>1</BankaID>
<TcKimlik>12345678912</TcKimlik></CC5Request>
</textarea>
<input type="submit" value="aaa" />
</form>
</body>
</html>

这不起作用>

String ali = "<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>xxxx</ClientId><IPAddress>213</IPAddress><Adress>asdsa</Adress>" +
"<OrderId>123</OrderId><Type>Auth</Type><Number>1234567891234567</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val>" +
"<Total>10</Total><Taksit></Taksit><Kdv>xx</Kdv><BankaID>1</BankaID><TcKimlik>12345678912</TcKimlik></CC5Request>";
WebRequest req = WebRequest.Create("http://www.pay-pos.com/test.php?datafromuser=" + ali);
req.Credentials = CredentialCache.DefaultCredentials;
req.Method = "POST";
HttpWebResponse loWebResponse = (HttpWebResponse)req.GetResponse();
Encoding enc = Encoding.GetEncoding(1254);

StreamReader loResponseStream =

new StreamReader(loWebResponse.GetResponseStream(), enc);

string lcHtml = loResponseStream.ReadToEnd();
loWebResponse.Close();
loResponseStream.Close();

编辑:实验 1

String postData = "Name=Mert" +
"&Password=123" +
"&ClientId=1058" +
"&IPAddress=213.456.654.456" +
"&Adress=asdsa" +
"&OrderId=123" +
"&Type=Auth" +
"&Number=4522115422659661" +
"&ExpiresAy=01" +
"&ExpiresYil=13" +
"&Cvv2Val=123" +
"&Total=10" +
"&Taksit=1" +
"&Kdv=18" +
"&BankaID=1" +
"&TcKimlik=12345678912";

string URI = "http://www.pay-pos.com/test.php";

WebClient wc = new WebClient();
wc.Headers["Content-type"] = "application/x-www-form-urlencoded";
string HtmlResult = wc.UploadString(URI, postData);

实验二

 HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.pay-pos.com/test.php");
request.Method = WebRequestMethods.Http.Post;
request.ContentLength = postData.Length;
request.ContentType = "application/x-www-form-urlencoded";
request.KeepAlive = false; //also tried true as well

StreamWriter writer = new StreamWriter(request.GetRequestStream());
writer.Write(postData);
writer.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
String responseString = reader.ReadToEnd();

response.Close();

实验 3!!!工作!!!

String ali = "datafromuser=<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>1058</ClientId><IPAddress>213.456.654.456</IPAddress><Adress>asdsa</Adress><OrderId>123</OrderId><Type>Auth</Type>" +
"<Number>4522115422659661</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val><Total>10</Total><Taksit></Taksit><Kdv>18</Kdv><BankaID>1</BankaID>"+
"<TcKimlik>12345678912</TcKimlik></CC5Request>";

byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(ali);

WebRequest req = WebRequest.Create("http://www.pay-pos.com/test.php");

req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = byteArray.Length;
req.Method = "POST";

Stream dataStream = req.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

HttpWebResponse response = (HttpWebResponse)req.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
String responseString = reader.ReadToEnd();

response.Close();

最佳答案

我首先看到的错误是您试图使用查询字符串来发布表单数据。你的“表单数据”应该是这样的:

 String ali = "datafromuser=<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>xxxx</ClientId><IPAddress>213</IPAddress><Adress>asdsa</Adress>" +
"<OrderId>123</OrderId><Type>Auth</Type><Number>1234567891234567</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val>" +
"<Total>10</Total><Taksit></Taksit><Kdv>xx</Kdv><BankaID>1</BankaID><TcKimlik>12345678912</TcKimlik></CC5Request>";

接下来,您需要从表单数据中获取 bytes[]。

byte[] byteArray = Encoding.UTF8.GetBytes(ali);

设置一些标题:

req.ContentType = "application/x-www-form-urlencoded"; 
req.ContentLength = byteArray.Length;
req.Method = "POST";

现在将您的数据写入请求流。

Stream dataStream = req.GetRequestStream(); 
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

终于......得到你的回应。另请注意,任何实现 IDisposable 的内容都应包含在 using 语句中,即 StreamWebResponse

另请注意,提交按钮不是表单发布数据的一部分。有可能服务器期望它。

编辑:这是 Microsoft 提供的一个完整示例,可指导您逐步进行操作。
