使 httpClient 支持中文

一个有效的方法：重载 PostMethod 的 getRequestCharSet 方法

   1: class PostChinese {

   2:     HttpClient httpClient = new HttpClient();

   3:     PostMethod postMethod = new UTF8PostMethod("http://xxxxxxxx");

   4:     NameValuePair p1 = new NameValuePair("hello", "你好");

   5:     NameValuePair p2 = new NameValuePair("world", "世界");

   6:     postMethod.setRequestBody(new NameValuePair[] {p1, p2});

   7:     try {

   8:         httpClient.executeMethod(postMethod);

   9:     } catch (HttpExeception e) {

  10:         e.printStackTrace();

  11:     } catch (IOException e) {

  12:         e.printStackTrace();

  13:     }

  14:     httpPost.releaseConnection();

  15: };

  16:  

  17: class UTF8PostMethod extends PostMethod {

  18:     public UTF8PostMethod(String url) {

  19:         super(url);

  20:     }

  21:     @Override

  22:     public String getRequestCharSet() {

  23:         return "UTF-8";

  24:     }

  25: };
