这里只介绍如何使用HttpClient发起GET或者POST请求
GET 方式
复制代码 代码如下:
//先将参数放入List，再对参数进行URL编码
List
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
复制代码 代码如下:
//和GET方式一样，先将参数放入List
params = new linkedList
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();
}
