微信公众平台接口--JAVA示例

主逻辑代码

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

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

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

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

//获取输出流

response.setCharacterEncoding("UTF-8");

PrintWriter out = response.getWriter();

//校验,验证成功后注释掉，只是在第一次校验的时候使用

//接口说明的那些sha1加密比较signature目前没多大用

//out.(echostr);

//out.flush();

//out.close();

// 接收XML数据

BufferedReader br = new BufferedReader(new InputStreamReader((ServletInputStream)request.getInputStream(),"UTF-8"));

String line = null;

StringBuilder requestMsg = new StringBuilder();

while((line = br.readLine())!=null){

requestMsg.append(line);

}

br.close();

//解析数据

String reqXml = requestMsg.toString();

String fromUser = reqXml.substring(requestMsg.indexOf(""));

String toUser = reqXml.substring(reqXml.indexOf(" "));

String content = reqXml.substring(reqXml.indexOf(""));

//返回消息

out.print("");

out.print(" "); out.print(" "); out.print(" "+new Date().getTime()+""); out.print(" ");

out.print(" ");

out.print(" 0");

out.print("");

out.flush();

out.close();
