Question

我想在后面的代码中创建一个帖子。我有简单的html帖子正在工作但是当我尝试使它成为WebRequest我无法使它工作。

先谢谢你的时间。

这是有效的＆gt;

这不起作用＆gt;

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2

 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();

Answer 1

我看到错误的第一件事是您尝试使用查询字符串发布表单数据。您的“表单数据”应如下所示：

 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();

最后......得到你的回复。另请注意，任何实现IDisposable的内容都应包含在using语句中，即Stream和WebResponse。

另请注意，提交按钮不是表单发布数据的一部分。服务器可能会期待它。

这可能会对你有帮助。

string URI = "http://www.myurl.com/post.php";
string myParamters = "param1=value1&param2=value2";

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

Answer 3

这是一个简单的例子。 postData取决于表单

String postData = "Name=" + Username +
              "&Password=" + Password +
              "&Retype=" + Password +
              "&Email=" + HttpUtility.UrlEncode(EmailAddress) +
              "&RealName=" + String.Format("{0}+{1}", FirstName.Replace(" ", "+"), LastName.Replace(" ", "+"));

现在创建请求并发布数据：

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method = WebRequestMethods.Http.Post;
request.ContentLength = postData.Length;
request.ContentType = "application/x-www-form-urlencoded";
request.KeepAlive = false;

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();

您可以使用Fiddler来捕捉postData的外观。

Answer 4

试试这样。

using (WebClient client = new WebClient())
   {

       byte[] response = client.UploadValues("http://dork.com/service", new NameValueCollection()
       {
           { "home", "Cosby" },
           { "favorite+flavor", "flies" }
       });
   }

您将需要以下内容：

using System;
using System.Collections.Specialized;
using System.Net;

如果您坚持使用静态方法/类：

public static class Http
{
    public static byte[] Post(string uri, NameValueCollection pairs)
    {
        byte[] response = null;
        using (WebClient client = new WebClient())
        {
            response = client.UploadValues(uri, pairs);
        }
        return response;
    }
}

然后简单地说：

Http.Post("http://dork.com/service", new NameValueCollection() {
    { "home", "Cosby" },
    { "favorite+flavor", "flies" }
});

.net后面的代码表单
