Android中文URL乱码问题 解决

问题现象：在Android中通过HttpGet发送http请求时，url中的中文到了服务器就变成了乱码。代码如下：

HttpClient client = new DefaultHttpClient();

HttpParams httpParams = client.getParams();

HttpConnectionParams.setConnectionTimeout(httpParams, 10000);

HttpConnectionParams.setSoTimeout(httpParams, 180000);

HttpResponse response = client.execute(new HttpGet( "http://HakonZhao.com/FunnyList/a?name=小小研究院" ));

 

    解决：

    使用HttpPost来发送请求，并且用java.net.URLEncoder对中文字符进行编码，代码如下：

HttpPost httpPost = new HttpPost(new URI("http://HakonZhao.com/FunnyList/a"));

List<NameValuePair> urlParam = new ArrayList<NameValuePair>();

urlParam.add(new BasicNameValuePair("name", URLEncoder.encode("小小研究院 ")));

httpPost.setEntity( new UrlEncodedFormEntity(urlParam, HTTP.UTF_8));

client.execute(httpPost);

 

    在服务器端需要用URLDecoder对中文参数进行解码，代码如下：

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException 

{

request.setCharacterEncoding("UTF-8");

response.setCharacterEncoding("UTF-8");

String name = URLDecoder.decode( request.getParameter("name"), "UTF-8");
