那你要做的就是向这个URL发送数据就好，给个例子：
public class Httptest1 {
8
9 public static void main(String[] args) {
10
11 URL url = null ;
12 HttpURLConnection conn = null ;
13 OutputStream outStream = null ;
14 InputStream inStream = null ;
15
16 try {
17 url = new URL( " http://219.233.89.7:8090/cgi-bin/mailinterface " );
18 conn = (HttpURLConnection) url.openConnection();
19 conn.setDoOutput( true );
20 conn.setDoInput( true );
21
22 String sendXml = " <?xml version=\ " 1.0 \ " encoding=\ " UTF - 16 \ " ?><!DOCTYPE SigMailCommand SYSTEM \ " SigMail.dtd\ "> " ; // XML数据
23 sendXml += " <SigMailCommand Name=\ " checkuser\ " ><Param Name=\ " domainname\ " >test.com.cn</Param> " ;
24 sendXml += " <Param Name=\ " username\ " >admin</Param></SigMailCommand> " ;
25
26 outStream = conn.getOutputStream();
27
28 // 准备通过CONN对象写入XML数据
29 BufferedWriter bw = new BufferedWriter( new java.io.OutputStreamWriter(outStream,
30 " UTF-16 " ));
31 bw.write(sendXml);
32 bw.flush();
33 bw.close();
34
35 // DataOutputStream dataOutStream = new DataOutputStream(outStream);
36 // dataOutStream.writeChars(xml);
37 // dataOutStream.flush();
38 // dataOutStream.close();
39
40
41 // 准备通过CONN对象读取返回的XML数据
42
43 inStream = conn.getInputStream();
44 StringBuffer returnXml = new StringBuffer( "" );
45 BufferedReader rd = new BufferedReader( new InputStreamReader(inStream,
46 " UTF-16 " ));
47 for (String line = null ; (line = rd.readLine()) != null ;) {
48 returnXml.append(line);
49 }
50 System.out.println(returnXml.toString());
51 rd.close();
52 } catch (IOException ex) {
53 ex.printStackTrace();
54 } finally {
55 try {
56 if (outStream != null )
57 outStream.close();
58 if (inStream != null )
59 inStream.close();
60 if (conn != null )
61 conn.disconnect();
62 } catch (IOException e) {
63 // TODO 自动生成 catch 块
64 e.printStackTrace();
65 }
66 }
67
68 }
69
70 }
