这里只介绍如何使用HttpClient发起GET或者POST请求
GET 方式
Java代码
- //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
Java代码
- //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();
- }
