[英]HTTP post XML data in C#
我需要 HTTP 将 XML 数据发布到具有 XMLdata 名称的 Textarea 的 URL 中。 我的 XMl 数据已准备就绪,位于 XDocument Sendingxml = xml 内部; 但我尝试过的邮政编码不起作用。 主要是因为我不知道如何将 XML 数据放入 postData 变量中,因为它只接受字符串。 这是我的代码:
XDocument Sendingxml = xml;
// string Sendingxml = "<?xml version=1.0 encoding=UTF-8> <PluginData> <Credential UserName=avosfieldagent01 AuthenticationToken=61cc3957744742dca238c4dd7cbca702 /><Session><PropertyAddress>5 Crosskey</PropertyAddress><PropertyAddress2/><PropertyCity>California</PropertyCity><PropertyState>CA</PropertyState><PropertyZip>92620</PropertyZip><PropertyType>Condo</PropertyType><SourceReferenceId>45643</SourceReferenceId><SessionId>2013070100158346</SessionId><SessionCompleteReturnURL/><CustomerId/><BluebookOrderCheckSum>681a598cf23f412095f6092c281823e6</BluebookOrderCheckSum><BluebookOrderId>11160</BluebookOrderId> </Session></PluginData>";
// Create a request using a URL that can receive a post.
WebRequest request =
WebRequest.Create("https://test.bluebookcva.net/order/testdirectplugin/3");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "XMLData=" + Sendingxml; //My problem is here as I need postData as XDocument.
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
一般来说:
下面的函数是一种简单的方法来发布XML数据并获取响应(作为字符串)的示例:
public string postXMLData(string destinationUrl, string requestXml)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
byte[] bytes;
bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
request.ContentType = "text/xml; encoding='utf-8'";
request.ContentLength = bytes.Length;
request.Method = "POST";
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
HttpWebResponse response;
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
string responseStr = new StreamReader(responseStream).ReadToEnd();
return responseStr;
}
return null;
}
在您的特定情况下:
代替:
request.ContentType = "application/x-www-form-urlencoded";
采用:
request.ContentType = "text/xml; encoding='utf-8'";
另外,删除:
string postData = "XMLData=" + Sendingxml;
并替换:
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
有:
byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());
AlliterativeAlice的榜样极大地帮助了我。 不过,就我而言,与我交谈的服务器不喜欢在内容类型的utf-8
周围加上单引号。 它因通用的"Server Error"
而失败,花了数小时才弄清它不喜欢的内容:
request.ContentType = "text/xml; encoding=utf-8";
我从代码中收到此错误
无法发送具有此动词类型的内容主体
