Android HttpClient基本使用方法

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();  
}
