[HttpClient]HTTPClient PostMethod 中文乱码问题解决方案（2种） - 追竹 - 博客频道 - CSDN.NET

一、在调用PostMethod方法时设置字符编码：

 

PostMethod postMethod = new PostMethod(
        "http://127.0.0.1:8080/HttpClientServer/login.do");
postMethod.getParams(). setParameter( HttpMethodParams.HTTP_CONTENT_CHARSET,"utf-8");

 

 

 

二、重载PostMethod的getRequestCharSet()方法, 返回我们需要的编码(字符集)名称, 就可以解决 UTF-8 或者其它非默认编码提交 POST 请求时的乱码问题了.

 

 

//Inner class for UTF-8 support
   public static class UTF8PostMethod extends PostMethod{
       public UTF8PostMethod(String url){
           super(url);
       }
       @Override
       public String getRequestCharSet() {
           //return super.getRequestCharSet();
           return "utf-8";
       }
   }

 

 

PostMethod postMethod = new UTF8PostMethod(
                "http://127.0.0.1:8080/HttpClientServer/login.do");

 

 

三、最后服务器端要配合客户端，设置下编码字符集：

 

public void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    //解决中文乱码问题，此步不可少
    request.setCharacterEncoding("UTF-8");
    response.setContentType("text/html");
    response.setCharacterEncoding("UTF-8");
    PrintWriter out = response.getWriter();
    String username = (String) request.getParameter("username");
    String password = (String) request.getParameter("password");
    System.out.println("******************** doPost被执行了 ********************");
    System.out.println("您的请求参数为:/tusername:" + username + "/tpassword:"
            + password);
    out.print("您的请求参数为:/tusername:" + username + "/tpassword:" + password);
    out.flush();
    out.close();
}
