微信api接口操作示例

一、服务器基本信息交互

public class WeiXinServlet extends HttpServlet{ private static final long serialVersionUID = 1L;
 /** * 确认请求来自微信服务器 */ 
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // 微信加密签名  String signature = request.getParameter("signature"); // 时间戳  String timestamp = request.getParameter("timestamp"); // 随机数  String nonce = request.getParameter("nonce"); // 随机字符串  String echostr = request.getParameter("echostr");  

        PrintWriter out = response.getWriter(); // 通过检验signature对请求进行校验,若校验成功则原样返回echostr,表示接入成功,否则接入失败  if (SignUtil.checkSignature(signature, timestamp, nonce)) {  
            out.print(echostr);
        }  
        out.close();  
        out = null;  
    } 
/** * 处理微信服务器发来的消息  */ 
public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException { // 将请求、响应的编码均设置为UTF-8(防止中文乱码)  request.setCharacterEncoding("UTF-8");  
            response.setCharacterEncoding("UTF-8"); // 调用核心业务类接收消息、处理消息  String respMessage = CoreService.processRequest(request); // 响应消息  PrintWriter out = response.getWriter();  
            out.print(respMessage);  
            out.close();  
    }  
}
