如何发送此HttpWebRequest? [英] how to send this HttpWebRequest ?

问题描述

嘿，

第三方给了我一个从黑莓设备发送的http请求跟踪转储:

hey,

a 3rd party gave me an http request trace dump sent from a black berry device:

POST /maveo1 HTTP/1.1
Host: au1.blahblah.com.au:6226
Connection: close
User-Agent: mView1/4.3.0
Content-Length: 26
Command=SNAP&Timestamp=0

黑莓的代码是:(代码已更新)

the code at black berry is : (code updated)

HttpConnection httpConnection = (HttpConnection) Connector.open("http://" + _thrdOwner.getWebServiceURLforViewerAccount());
      httpConnection.setRequestMethod(HttpConnection.POST);
      httpConnection.setRequestProperty("User-Agent", "mView/4.3.0 (Blackberry OS)");

      out = httpConnection.openOutputStream();
      String sCommand = command1.toString() + "&" + command2.toString() + "="
          + value1.toString() + "" + value2.toString() + "\r\n";

      out.write(sCommand.getBytes());
      out.flush(); // This forces the POST to happen

      responseCode = httpConnection.getResponseCode();

并要求我在按钮上单击上方的http请求来发送以触发一些命令，当我问他们可以给我一个uri或Web服务路径等时，他们说我们已经发送的内容就足够了.

我尝试执行以下操作，并且成功了:(代码已更新)

and asking me to send above http request on a button click on a web page to trigger some command, when I ask them can they give me a uri or web service path etc. They say what we have send is enough.

I tried doing the below and it worked: (Code Updated)

HttpWebRequest myHttpWebRequest =(HttpWebRequest)WebRequest.Create("http://au1.blahblah.com.au:6226/maveo1");
             myHttpWebRequest.Method = "POST";
      myHttpWebRequest.UserAgent = "mView/4.5.0";

      string postData = "Command=SNAP&Timestamp=0\n";
      ASCIIEncoding encoding = new ASCIIEncoding ();
      byte[] byte1 = encoding.GetBytes (postData);
      myHttpWebRequest.ContentLength = byte1.Length;
      Stream newStream = myHttpWebRequest.GetRequestStream ();
      newStream.Write (byte1, 0, byte1.Length);
      newStream.Close ();
      WebResponse resp = myHttpWebRequest.GetResponse();

所以我复制了如下的http请求:

so i reproduced the http reques like below:

POST /maveo/ HTTP/1.1

Host: au1.blahblah.com.au:6226

Content-Length: 24

Expect: 100-continue



HTTP/1.1 100 Continue

server: m-View HTTP Service/4.5.0.12

date: Tue, 07 Jun 2011 17:38:25 GMT



Command=SNAP&Timestamp=0HTTP/1.1 200 OK

server: m-View HTTP Service/4.5.0.12

date: Tue, 07 Jun 2011 17:38:25 GMT

connection: close

现在，您在http帖子中说期望:100-继续"可以消除它...

Now y the http post is saying ''Expect: 100-continue'' can we get rid of it...

推荐答案

我注意到您的代码未指定HttpWebRequest.Method，必须为"POST"，具体取决于您要复制的HTTP转储.


回答后续问题:
HTTP标准的文本在此处说明了"Expect: 100-continue"的使用:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html [ ^ ].

我认为您不需要摆脱它" :-).

I noticed your code does not specify HttpWebRequest.Method, with must be "POST", according to your HTTP dump which you''re trying to reproduce.


Answering a follow-up question:
The use of "Expect: 100-continue" is explained in the text of HTTP standard here:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html[^].

I don''t think you need to "get rid of it" :-).
