Need help with HttpWebRequest on a Compact Framework Project
提问by Jerther
not so long ago I′ve created a small iphone app for my Daily use. Now I want to port this app to a Windows Mobile Device while using C# and the Compact Framework. But I really have no clue how to use the HttpWebRequest and the msdn doesn′t help me either. I think I have a lag of understanding on how Web Requests work in general.
不久前，我创建了一个小 iphone 应用程序供我日常使用。现在我想在使用 C# 和 Compact Framework 的同时将此应用程序移植到 Windows Mobile 设备。但我真的不知道如何使用 HttpWebRequest 并且 msdn 也没有帮助我。我认为我对 Web 请求的一般工作方式理解滞后。
In the iPhone app I have the following lines code:
在 iPhone 应用程序中，我有以下几行代码：
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://xxx:[email protected]/RPC2"]];
[theRequest setHTTPMethod:@"POST"];
[theRequest addValue:@"text/xml" forHTTPHeaderField:@"content-type"];
[theRequest setCachePolicy:NSURLCacheStorageNotAllowed];
[theRequest setTimeoutInterval:5.0];
NSString* pStr = [[NSString alloc] initWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?><methodCall><methodName>xxx.SessionInitiate</methodName><params><param><value><struct><member><name>LocalUri</name><value><string></string></value></member><member><name>RemoteUri</name><value><string>xxxx</string></value></member><member><name>TOS</name><value><string>text</string></value></member><member><name>Content</name><value><string>%@</string></value></member><member><name>Schedule</name><value><string></string></value></member></struct></value></param></params></methodCall>", number.text, TextView.text];
NSData* pBody = [pStr dataUsingEncoding:NSUTF8StringEncoding];
[theRequest setHTTPBody:pBody];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
The Webservice has no wsdl so I have to use the HttpWebRquest Object in .Net CF. What I didn′t get is, where to put the Body (the long XML) in my Request?
Webservice 没有 wsdl，所以我必须在 .Net CF 中使用 HttpWebRquest 对象。我没有得到的是，在我的请求中将正文（长 XML）放在哪里？
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(@"https://xxx:[email protected]/RPC2");
req.Method = @"POST";
req.ContentType = @"test/xml";
req.Timeout = 5;
I started this way, is the first line it′s own HttpWebRequest and for the XML Body I have to create anotherone?! How do I use it correctly, how do I send it? Sorry if this might be normaly totaly easy but I really don′t get it. I′ve searched the web, 2 Books and the msdn but in every tutorial is only a Webrequest with an URL but without a body.
我是这样开始的，第一行是它自己的 HttpWebRequest 并且对于 XML Body 我必须创建另一个？！如何正确使用，如何发送？对不起，如果这可能很容易，但我真的不明白。我在网上搜索了 2 本书和 msdn，但在每个教程中都只有一个带有 URL 但没有正文的 Web 请求。
Thank you
谢谢

You need to write the POST data to the request stream.
您需要将 POST 数据写入请求流。
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(@"https://username:[email protected]/RPC2");
req.Method = "POST";
req.ContentType = "test/xml";
req.Timeout = 5;
using (Stream stream = req.GetRequestStream())
using (StreamWriter writer = new StreamWriter(stream, Encoding.UTF8))
{
writer.Write("PUT THE XML HERE");
}
using (StreamReader reader = req.GetResponse().GetResponseStream())
{
string result = reader.ReadToEnd();
}

BEWARE, if there's no data to write to the stream, the ContentLengthwould be 0 but oddly you STILL need to Dispose()the RequestStream even if you don't write anything to it!!!
请注意，如果没有要写入流的数据，则该ContentLength值为 0，但奇怪的是Dispose()，即使您不向其中写入任何内容，您仍然需要使用 RequestStream ！！！
req.ContentLength = 0;
req.GetRequestStream().Dispose();
This problem only happens in Compact Framework.
这个问题只发生在 Compact Framework 中。

Get the request stream using
使用获取请求流
Stream requestStream = req.GetRequestStream();
Then write your xml data to the stream, taking care to encode your text.
然后将您的 xml 数据写入流，注意对您的文本进行编码。
Don't forget to close the stream to ensure that all of your data is sent.
不要忘记关闭流以确保发送所有数据。
requestStream.Close();
