我的任务
分享用JAVA模拟POST发送数据
现在要做一个独立的程序,要求与另一个软件提供商进行数据交换,对方要求交换程序按以下要求来做:
1、POST 方式传递数据
2、输入方式必须是： multipart/form-data
3、必须用 requestxml 作为输入变量
4、传递的数据必须是 XML 格式
有哪位可以提供思路,或者代码参考.
谢谢!

在 xiaohuasz() 发的内容中有这样一句conn.setRequestProperty("Referer","http://203.238.87.206/send2.asp"); 有两个问题，1、不太明白它的意思；2、第二参数是起什么作用的，它与 URL servlet = new URL("http://61.74.66.185/p/send_notip.asp"); 这一句中的URL啷个不一样哩？
请大家继续讨论！
谢谢了

1.可以设置
2.输出方式需遵循一定规则

HttpURLConnection conn = new HttpURLConnectino(URL url)
方法根本不能用啊，是抽象的？怎么办呢？

谢谢各位的意见，我的做法跟楼上的 jFresH_MaN 和 xiaohuasz() 的大同小异，现在出现的问题是，
1、输入方式必须是： multipart/form-data ，在程序中能不能够conn.setRequestProperty("Content-Type", "multipart/form-data");这样设置？？？？
2、必须用 requestxml 作为输入变量，考虑可能是另一个软件提供商用这个变量来接收值，那么在程序中能不能用后边的这些语句？ OutputStreamWriter out = new OutputStreamWriter(uc.getOutputStream(), "8859_1"); out.write("requestxml="+strXML);
请各位帮着看一下。

使用Socket应该也能实现楼主所说的要求

服务器:
1.jsp
<body>
<form name="_ctl0" method="post" action="TestFileManager.aspx" id="_ctl0" enctype="multipart/form-data">
<input type="hidden" name="__VIEWSTATE" value="dDwyNTIzNjA5NDU7Oz7rsE3eBYzQHDVtl+aTn96MvQW6PQ==" />
<p>
<input name="uploadfile1" id="uploadfile1" type="file" size="49" />
<input type="submit" name="Button1" value="?" id="Button1" />
</p>
<p>
<span id="Label1" style="width:459px;"></span>
</p>
<!-- Insert content here -->
</form>
</body>
客户端:
首先创建一个到服务器http的请求
HttpRequest request = new HttpRequest("http://服务器/1.jsp");
第一次使用的是GET方式
request.setMethod("GET");
紧接着进行一些请求的属性设置
request.setRequestHeader("Cache-Control", "no-cache");
这里保持连接，因为后面还要发送数据到服务器呢
request.setRequestHeader("Connection", "Keep-Alive");
下面是一些无关紧要的属性设置了。
request.setRequestHeader("Accept", "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*");
request.setRequestHeader("Accept-Encoding", "gzip, deflate");
request.setRequestHeader("Accept-Language", "en-au");
request.setRequestHeader("Referer", "http://服务器/1.jsp");
request.setRequestHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3215; .NET CLR 1.0.3705)");
构造好了连接请求，然后连接
request.connect();
紧接着提取Cookie值，在后文的post中可以用到。
String strCookie = request.getResponseHeader("Set-Cookie");
strCookie = strCookie.substring(0,strCookie.indexOf(";"));
下面通过循环查找，提取__VIEWSTATE的值
for ( int i = 0; i < nlist.getLength(); i++) {
node = nlist.item(i);
strName = getNodeAttributeValue(node,"name");
if ( strName.equals("__VIEWSTATE") ) {
strValue = getNodeAttributeValue(node,"value");
break;
}
}
往服务器组织发送数据
DataOutputStream dos = new DataOutputStream(request.getOutputStream());
dos.writeBytes("-----------------------------"+strBoundary);//这是每个要被发送数据间的间隔
dos.writeBytes("\r\nContent-Disposition: form-data; name=\"__VIEWSTATE\"");
dos.writeBytes("\r\n\r\n"+strValue);
dos.writeBytes("\r\n-----------------------------"+strBoundary);
这里面是发送文件的部分
dos.writeBytes("\r\nContent-Disposition: form-data; name=\"uploadfile1\"; filename=\"" + strFileName + "\"");
dos.writeBytes("\r\nContent-Type: text/xml");
dos.writeBytes("\r\n\r\n");
dos.writeBytes(new String(data));
dos.writeBytes("\r\n-----------------------------"+strBoundary);
dos.writeBytes("\r\nContent-Disposition: form-data; name=\"Button1\"");
dos.writeBytes("\r\n上传");
dos.writeBytes("\r\n-----------------------------"+strBoundary+"--");
dos.writeBytes("\r\n");
dos.close();

// Using java.net.URL and
//java.net.URLConnection
URL url = new
URL("http://www.126.com/index_t.htm");
URLConnection connection = url.openConnection();
然后把连接设为输出模式。URLConnection通常作为输入来使用，比如下载一个Web页。通过把URLConnection设为输出，你可以把数据向你个Web页传送。下面是如何做：
...
connection.setDoOutput(true);
最后，为了得到OutputStream，简单起见，把它约束在Writer并且放入POST信息中，例如：
...
OutputStreamWriter out = new
OutputStreamWriter(uc.getOutputStream(), "8859_1");
out.write("username=bob&password="+password+"");
// remember to clean up
out.flush();
out.close();
这样就可以发送一个看起来象这样的POST：
POST www.126.net/index.html HTTP 1.0
ACCEPT: text/plain
Content-type: application/x-www-form-urlencoded
Content-length: 99
username=bob
password=someword
一旦发送成功，用以下方法就可以得到服务器的回应：
connection.getInputStream();
上面是发送字符串的，其实你要发送xml文件，只要把xml文件的内容保存成字符串发送过去就可以了
但是如果实在要使用multipart/form-data
那就要使用URLConnection的setContentHandlerFactory(ContentHandlerFactory fac)方法
然后写一个类实现Interface ContentHandlerFactory
这样就可以直接发送XML这个Object了
//java.net.URLConnection
URL url = new
URL("http://www.126.com/index_t.htm");
URLConnection connection = url.openConnection();
