求教java socket问题!急

Question

我要做一个从天气预报的网站取得数据的小程序,要求是用socket来做,那个服务器要求的格式是这样的:
POST /globalweather.asmx/GetCitiesByCountry HTTP/1.1
Host: www.webservicex.net
Content-Type: application/x-www-form-urlencoded
Content-Length: length
CountryName=string
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://www.webserviceX.NET">string </string> 我做了这个小程序,但无法得到正确结果, 我是按照它提供的格式写道out.write()中的啊,问题在哪?
import java.io.*;
import java.net.*;public   class   TCPClient   {  
          public   static   void   main(String   argv[])   throws   Exception   {  
                  final  int   HTTP_PORT   =   80;  
   
                  Socket   socket   =   new   Socket("www.webservicex.net",   HTTP_PORT);  
                  BufferedWriter   out  =   new   BufferedWriter(new   OutputStreamWriter(socket.getOutputStream()));  
                  BufferedReader   in  
                                  =   new   BufferedReader(new   InputStreamReader(socket.  
                                  getInputStream()));  
                  out.write("POST /globalweather.asmx/GetCitiesByCountry HTTP/1.1 Host: www.webservicex.net Content-Type: application/x-www-form-urlencoded Content-Length: 1024 CountryName=china");  
                  out.flush();  
   
                  String   line;  
                  StringBuffer   sb   =   new   StringBuffer();  
                  while   ((line   =   in.readLine())   !=   null)   {  
                          sb.append(line+"\r\n");  
                  }  
                  out.close();  
                  in.close();  
                  System.out.println(sb.toString());  
          }  
  }   

Answer 1

如果急,你就在web版和J2ee版再分别发贴问一下.

Answer 2

真是晕死      out.write("POST /globalweather.asmx/GetCitiesByCountry HTTP/1.1 Host: www.webservicex.net Content-Type: application/x-www-form-urlencoded Content-Length: 1024 CountryName=china"); 这样怎么可以呢？
应该      out.write("POST /globalweather.asmx/GetCitiesByCountry HTTP/1.1\r\n");
      out.write("Host: www.webservicex.net Content-Type: application/x-www-form-urlencoded\r\n")  
以此类推记住严格遵守协议规范，要换行

谢谢,我又重新写了一边,还是不行,请各位指教
import java.io.*;
import java.net.*;public class TCPClient   {  
   public static void main(String   argv[])throws Exception {  
      final int HTTP_PORT=80;  
      Socket socket1 = new Socket("www.webservicex.net", HTTP_PORT);  
      BufferedWriter out= new BufferedWriter(new OutputStreamWriter(socket1.getOutputStream()));  
      BufferedReader in=  new BufferedReader(new InputStreamReader(socket1.getInputStream()));  
      out.write("POST /globalweather.asmx/GetCitiesByCountry HTTP/1.1\r\n");
      out.write("Host: www.webservicex.net\r\n");
      out.write("Content-Type: application/x-www-form-urlencoded\r\n");
      out.write("Content-Length: 1024\r\n");
      out.write("\r\n");
      out.write("CountryName=china\r\n");
      out.flush();  
   
      String line;  
      StringBuffer sb=new StringBuffer();  
      while((line=in.readLine())!=   null)   {  
          sb.append(line+"\r\n");  
      }  
      out.close();  
      in.close();  
      System.out.println(sb.toString());  
    }  
  } 

Answer 4

对方系统是什么？linux吗？如果是的话去掉\r试试，或者直接out.writeln试试

Answer 5

换种 方式 ，这种 一般就是 java 使用 webService 方法 很多，直接使用HTTP 协议的 还有 使用 axis 的  ，方法 很多，

Answer 6

BufferedWriter out= new BufferedWriter(new OutputStreamWriter(socket1.getOutputStream())); 输出流你换成PrintWriter pw = new PrintWriter(socket1.getOutputStream(),true);
然后用pw.println("你要写到服务器的内容");    试试看。
建议楼主用个线程不停的去读服务器的返回，并打印在控制台，便于查找问题
