使用apache httpclient请求数据(get/post),同时支持代理

get方式获取数据，贴上代码

/**
	 * GET的方式请求
	 * @createDate: Apr 2, 2011 5:58:03 PM
	 * @param http_url
	 * @param isProxy
	 * @return
	 */
	public String doGet(String http_url, boolean isProxy) {
		HttpMethod method = null;
		try {
			URI uri = new URI(http_url, true);
			HttpClient client = new HttpClient();
			HostConfiguration hcfg = new HostConfiguration();
			hcfg.setHost(uri);
			client.setHostConfiguration(hcfg);
			if (isProxy) 
				setProxy(client);
			// 参数验证
			client.getParams().setAuthenticationPreemptive(true);
			// GET请求方式
			method = new GetMethod(http_url);
			client.executeMethod(method);
			System.out.println("state:" + method.getStatusLine());
			return method.getResponseBodyAsString();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
	}

 

 

POST方式获取数据,代码：

 

/**
	 * POST方式提交数据
	 * @createDate: Apr 2, 2011 5:58:03 PM
	 * @param http_url 
	 * @param isProxy
	 * @return
	 */
	public String doPost(String http_url, Map<String, String> paramaters,
			boolean isProxy) {
		PostMethod method = null;
		try {
			URI uri = new URI(http_url, true);
			HttpClient client = new HttpClient();
			HostConfiguration cf = new HostConfiguration();
			cf.setHost(uri);
			client.setHostConfiguration(cf);
			if (isProxy)
				setProxy(client);

			client.getParams().setAuthenticationPreemptive(true);
			method = new PostMethod(http_url);
			//添加参数
			if(paramaters!=null){
				Iterator<Entry<String, String>> its = paramaters.entrySet().iterator();
				while (its.hasNext()) {
					Entry<String, String> e = its.next();
					method.addParameter(e.getKey(), e.getValue());
				}
			}
			client.executeMethod(method);
			// 打印服务器返回的状态
			System.out.println(method.getStatusLine());
			// 输出返回的信息
			return method.getResponseBodyAsString();
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			// 释放连接
			if(method!=null)
				method.releaseConnection();
		}
		return null;
	}

 

 

方法中使用到的代理,代码

 

 /**
  * 设置代理
  * @createDate: Apr 2, 2011 6:03:30 PM
  * @param client
  */
 private void setProxy(HttpClient client) {
  // 设置代理
  client.getHostConfiguration().setProxy(HTTP_HOST, HTTP_PORT);
  client.getState().setProxyCredentials(AuthScope.ANY,
    new UsernamePasswordCredentials(HTTP_USER, HTTP_PWD));
 }

 

 

附上测试代码

 

//get测试代码
String str_url = "http://mingnjintian-163-com.iteye.com/blog/985124";
new RequestManager().doGet(str_url,true);
		
//post测试代码
str_url = "http://mingnjintian-163-com.iteye.com/blog/985124";
new RequestManager().doPost(str_url, new HashMap<String, String>(),true);
