c#中post xml数据，并带参数_已解决_博问

哥，其实是这样的，这是我写的代码：

if(requestMessage.Content.Contains("我要上网"))
            {
                if (UserProfile.UserCode == "6d4603790dfc47bbb4cacde8f24e6fb7")
                {
                    string res = string.Format(@"<xml>
                                   <ToUserName><![CDATA[{0}]]></ToUserName>
                                   <FromUserName><![CDATA[{1}]]></FromUserName>
                                    <CreateTime>{2}</CreateTime>
                                    <MsgType><![CDATA[{3}]]></MsgType>
                                    <Content><![CDATA[{4}]]></Content>
                                   </xml> ",
                    requestMessage.FromUserName, requestMessage.ToUserName, DateTime.Now, requestMessage.MsgType, requestMessage.Content);
                    string ss=callProxy("", res);
                    var responseMessage = CreateResponseMessage<ResponseMessageText>();
                    responseMessage.Content = ss;
                    return responseMessage;
                }
            }

我要向一个服务器url post 类型为xml的数据，所以，我就拼接了res,但是，我还有Signature,Timestamp,Nonce 这几个参数也要传过去，所以，我不知道怎么写代码

我的post代码如下：

  public static string HttpPost(string Url, string Sign,string Timesp,string Non,string postStr)

            Timesp = System.Web.HttpUtility.UrlEncode(Timesp, System.Text.Encoding.UTF8);
            Non = System.Web.HttpUtility.UrlEncode(Non, System.Text.Encoding.UTF8);
            postStr = System.Web.HttpUtility.UrlEncode(postStr, System.Text.Encoding.UTF8);

            string postData = string.Format("postDataStr={0}&Sign={1}&Timesp={2}&Non={3}", postStr, Sign, Timesp, Non); // 要发放的数据
            byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(postData);

            //请求
            request = (HttpWebRequest)WebRequest.Create(Url);
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = Encoding.UTF8.GetByteCount(postData);
            Stream myRequestStream = request.GetRequestStream();
            StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312"));
            myStreamWriter.Write(byteArray);
            myStreamWriter.Close();


            //读取
            response = (HttpWebResponse)request.GetResponse();
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("gb2312"));
            string retString = myStreamReader.ReadToEnd();
            myStreamReader.Close();
            myResponseStream.Close();

            return retString;

@魔女小溪: 请问你这几个参数“Signature,Timestamp,Nonce”是对应 url 参数，还是对应 Request Entity Body 呢？

Launcher | 园豆：45050 (高人七级) | 2015-02-10 11:43

@Launcher: 对应url的

福气满满好运连连 | 园豆：94 (初学一级) | 2015-02-10 11:45

@魔女小溪:

request.ContentLength = Encoding.UTF8.GetByteCount(postData);

StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312"));

这两行代码不匹配，要么都用 UTF8，要么都用 GB2312，

@Launcher: 抛出来的异常，我用写入到记事本上面了，我正在安装fiddler

@魔女小溪: 有异常，你不会看下 stack 和 innerexception ?

Launcher | 园豆：45050 (高人七级) | 2015-02-11 17:10

@Launcher: 额，我不知道，怎么去看，因为我是在微信中，通过发送关键字，来触发这个post提交的

@Launcher: 呜呜呜，我笨！

@Launcher: 呵呵，错误来了，是我太笨了

@魔女小溪:

myStreamWriter.Write(postXml); 后 myStreamWriter.Flush();

检查下 request.ContentLength 的大小。

Launcher | 园豆：45050 (高人七级) | 2015-02-11 17:32

@Launcher: request.ContentLength=10

@魔女小溪: 用 Fiddler 或火狐的poster 测试过了吗？

Launcher | 园豆：45050 (高人七级) | 2015-02-12 09:21

@Launcher: 我刚刚去网上找了一段post提交的代码，粘贴到我的项目中，把之前写的注释了，结果，成功了，但是，之后又不成功了，而且还没有错误！莫名其妙呀！

福气满满好运连连 | 园豆：94 (初学一级) | 2015-02-12 09:48

@Launcher: 我想请问一下，就是，是不是post一次之后，如果在post的话，有啥要求呢？

福气满满好运连连 | 园豆：94 (初学一级) | 2015-02-12 09:56

@魔女小溪: 再 post ，就再 Create 一个 HttpWebRequest。

Launcher | 园豆：45050 (高人七级) | 2015-02-12 09:58

@Launcher: 请问一下，火狐的poster里面怎么添加 xml数据，我只知道添加参数

福气满满好运连连 | 园豆：94 (初学一级) | 2015-02-12 10:36

@Launcher: 我终于找到原因了，(⊙o⊙)…，就是

我把下面的参数值，直接写死他就成功，就是第二个，第一个是不行的，所以，但是，我传过来都是有值的，所以，应该是哪里拼接出问题了还是不知怎么的

1、string postData = string.Format("?Sign={0}&Timesp={1}&Non={2}",Sign, Timesp, Non); // 其他参数
2、string postData = "?Sign=58&Timesp=656&Non=5453";

福气满满好运连连 | 园豆：94 (初学一级) | 2015-02-12 10:54

@魔女小溪: 你检查这几个参数传入的值是多少，以及你最后 Url +postData 的值是多少。

Launcher | 园豆：45050 (高人七级) | 2015-02-12 11:02

@Launcher: 出了这样的错误：

@Launcher: 哈哈，大神，你骂我吧，是我太粗心了，参数放错位置了，参天呀，我怎么也是个女的呀！
