[HttpClient]HTTPClient PostMethod 中文乱码问题解决方案(2种)

HTTPClient PostMethod 中文乱码问题解决方案(2种)

 

Apache HttpClient ( http://jakarta.apache.org/commons/httpclient/ ) 是一个纯 Java 的HTTP 协议的客户端编程工具包, 对 HTTP 协议的支持相当全面, 更多细节也可以参考IBM 网站上的这篇文章 HttpClient入门 (http://www.ibm.com/developerworks/cn/opensource/os-httpclient/ ).

 

不过在实际使用中, 还是发现按照最基本的方式调用 HttpClient 时, 并不支持 UTF-8 编码。

 

现在给出2个解决方案:

 

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();  
}
