微信開放平臺接口java版

  模仿php，用servlet寫了一個接口.調試成功.

   

   public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

        //System.out.println("i am ok");

String signature=request.getParameter("signature");

String timestamp=request.getParameter("timestamp");

String nonce=request.getParameter("nonce");

String echostr=request.getParameter("echostr");

String token="169gold";//這個作用主要是生成驗證字符串吧。。我也搞不清。。。隨便寫                     

   

String[] str={token,timestamp,nonce};

   Arrays.sort(str);

   String bigStr=str[0]+str[1]+str[2];

        String digest = new SHA1().getDigestOfString(bigStr.getBytes()).toLowerCase(); 

        if(digest.equals(signature)){

    response.setCharacterEncoding("utf-8");

    System.out.println(echostr);

    BufferedReader sis = request.getReader();

 char[] buf = new char[1024];

 int len = 0;

 StringBuffer sb = new StringBuffer();

 while((len = sis.read(buf))!= -1){

  sb.append(buf,0,len);

 }       

       //System.out.println(sb.toString()+";;;;;;;");

       response.setContentType("text/xml");

       response.getWriter().print("<?xml version=\"1.0\"?><xml><ToUserName><![CDATA[o3B6FjkJtJB_VCQnbMH65lA_6l2s]]></ToUserName>"+

"<FromUserName><![CDATA[gh_53d680696bf4]]></FromUserName>"+

"<CreateTime>1357449401</CreateTime>"+

"<MsgType><![CDATA[text]]></MsgType>"+

"<Content><![CDATA[歡迎來到黃金臺]]></Content>"+

"</xml>");

    response.getWriter().print(echostr);

   

        }

}

然後從網上搜到一個SHAI的加密類
