本文详细介绍了如何使用HttpClient发起GET和POST请求，包括参数的URL编码、URL与参数的拼接、发送请求及获取响应码和内容的方法。

这里只介绍如何使用HttpClient发起GET或者POST请求

GET 方式

//先将参数放入List，再对参数进行URL编码
List<BasicNameValuePair> params = new LinkedList<BasicNameValuePair>();
params.add(new BasicNameValuePair("param1", "中国"));
params.add(new BasicNameValuePair("param2", "value2"));

//对参数编码
String param = URLEncodedUtils.format(params, "UTF-8");

//baseUrl			
String baseUrl = "http://ubs.free4lab.com/php/method.php";

//将URL与参数拼接
HttpGet getMethod = new HttpGet(baseUrl + "?" + param);
			
HttpClient httpClient = new DefaultHttpClient();

try {
    HttpResponse response = httpClient.execute(getMethod); //发起GET请求

    Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码
    Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8"));//获取服务器响应内容
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

POST方式

//和GET方式一样，先将参数放入List
params = new LinkedList<BasicNameValuePair>();
params.add(new BasicNameValuePair("param1", "Post方法"));
params.add(new BasicNameValuePair("param2", "第二个参数"));
			
try {
    HttpPost postMethod = new HttpPost(baseUrl);
    postMethod.setEntity(new UrlEncodedFormEntity(params, "utf-8")); //将参数填入POST Entity中
				
    HttpResponse response = httpClient.execute(postMethod); //执行POST方法
    Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码
    Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8")); //获取响应内容
				
} catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
