HttpClient 用于HttpPost请求

使用HTTP POST 与HTTP GET类似，只是增加了创建包含NameValuePair对象实例的列表，使用UrlEncodedFormEntity包装列表.

 

public String executeHttpPost() throws Exception {
		BufferedReader in = null;
		try {
			// 定义HttpClient
			HttpClient client = new DefaultHttpClient();
			
			 
			// 实例化HTTP方法
			HttpPost request = new HttpPost("****");
			
			// 创建名/值组列表
			List<NameValuePair> parameters = new ArrayList<NameValuePair>();
			parameters.add(new BasicNameValuePair("***", "***"));
			parameters.add(new BasicNameValuePair("***", "***"));
			

			// 创建UrlEncodedFormEntity对象
			UrlEncodedFormEntity formEntiry = new UrlEncodedFormEntity(
					parameters);
			request.setEntity(formEntiry);
			// 执行请求
			HttpResponse response = client.execute(request);

			in = new BufferedReader(new InputStreamReader(response.getEntity()
					.getContent()));
			StringBuffer sb = new StringBuffer("");
			String line = "";
			String NL = System.getProperty("line.separator");
			while ((line = in.readLine()) != null) {
				sb.append(line + NL);
			}
			in.close();
			String result = sb.toString();
			return result;
	 
		} finally {
			if (in != null) {
				try {
					in.close();
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		}
	}
