 上面为：chWeather.js

 

package com.ch.util;

import java.io.IOException;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.GetMethod;

public class DataHttpClient {
	
	public String getWeaherData(String url){
        HttpClient http = new HttpClient();
        
        if(null == url || url.equals("")){
        	url="http://m.weather.com.cn/data/101110101.html";//默认西安的天气
        }
        HttpMethod method = new GetMethod(url);  
        String data = "";
  
        try {
			http.executeMethod(method);
			
			System.out.println(method.getStatusLine());  
			int i = method.getStatusCode();
			
			if(vilidateStatus(i)){
				
				data = method.getResponseBodyAsString();
			}
	        
	        
	        System.out.println("我来看看"+data);
		} catch (HttpException e) {
			System.out.println(e.getMessage());
			return null;
			
		} catch (IOException e) {
			System.out.println(e.getMessage());
			return null;
		}  
        // 打印服务器返回的状态  
        
        
        return data;
	}
	public boolean vilidateStatus(int i){
		
		if(i==200){
			return true;
		}
		
		return false;
	}

}

 上面为：DataHttpClient.java

 

 

另外附上源码
