java中httpclient实现digest验证的请求

1、首先介绍如何使用HttpClient发起GET和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 = "

 

 

//将URL与参数拼接

HttpGet getMethod = new HttpGet(baseUrl + "?" + param);

             

HttpClient httpClient = new DefaultHttpClient();

 

try {

    HttpResponse response = httpClient.execute(getMet搜索hod); //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();

}
