httpClient中文乱码问题解决（wap提交）

     我在尝试着直接将中文改变为utf-8的字符串直接写入，失败后！以为是网络传输中应该是iso-8859-1方式传输的，然后将中文转为该编码格式，还是失败后，看httpclient源代码发现：重写postmethod中的getrequestcharset()方法，虽然源代码中该方法动态的设置编码格式，但是好像并没有很好的执行！在重写后，问题解决！

    origin.setLength(0);

  HttpClient httpClient = new HttpClient();

  NameValuePair a = new NameValuePair("a","**");
  NameValuePair q = new NameValuePair("q","**");
  NameValuePair[] param = new NameValuePair[]{a,q};

  postMethod.setRequestBody(param);

      System.err.println("Method failed: "+ postMethod.getStatusLine());
