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

Java代码

1. //先将参数放入List，再对参数进行URL编码
2. List<BasicNameValuePair>params=newLinkedList<BasicNameValuePair>();
3. params.add(newBasicNameValuePair("param1","中国"));
4. params.add(newBasicNameValuePair("param2","value2"));
6. //对参数编码
7. Stringparam=URLEncodedUtils.format(params,"UTF-8");
9. //baseUrl
10. StringbaseUrl="http://ubs.free4lab.com/php/method.php";
12. //将URL与参数拼接
13. HttpGetgetMethod=newHttpGet(baseUrl+"?"+param);
15. HttpClienthttpClient=newDefaultHttpClient();
17. try{
18. HttpResponseresponse=httpClient.execute(getMethod);//发起GET请求
20. Log.i(TAG,"resCode="+response.getStatusLine().getStatusCode());//获取响应码
21. Log.i(TAG,"result="+EntityUtils.toString(response.getEntity(),"utf-8"));//获取服务器响应内容
22. }catch(ClientProtocolExceptione){
23. //TODOAuto-generatedcatchblock
24. e.printStackTrace();
25. }catch(IOExceptione){
26. //TODOAuto-generatedcatchblock
27. e.printStackTrace();
28. }

POST方式

Java代码

1. //和GET方式一样，先将参数放入List
2. params=newLinkedList<BasicNameValuePair>();
3. params.add(newBasicNameValuePair("param1","Post方法"));
4. params.add(newBasicNameValuePair("param2","第二个参数"));
6. try{
7. HttpPostpostMethod=newHttpPost(baseUrl);
8. postMethod.setEntity(newUrlEncodedFormEntity(params,"utf-8"));//将参数填入POSTEntity中
10. HttpResponseresponse=httpClient.execute(postMethod);//执行POST方法
11. Log.i(TAG,"resCode="+response.getStatusLine().getStatusCode());//获取响应码
12. Log.i(TAG,"result="+EntityUtils.toString(response.getEntity(),"utf-8"));//获取响应内容
14. }catch(UnsupportedEncodingExceptione){
15. //TODOAuto-generatedcatchblock
16. e.printStackTrace();
17. }catch(ClientProtocolExceptione){
18. //TODOAuto-generatedcatchblock
19. e.printStackTrace();
20. }catch(IOExceptione){
21. //TODOAuto-generatedcatchblock
22. e.printStackTrace();
23. }
