微信公众平台接口调用(java版)

首先是一个 servlet：

package com.baitw;

import java.io.BufferedReader;

import java.io.IOException;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.util.Arrays;

import java.util.List;

import com.baitw.dao.impl.NodeDaoImpl;

import com.baitw.hibernate.entity.TChannelnode;

public class WeixinServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

public static final String Token = "token";

/**

* 用来接收微信公众平台的验证

*/

@Override

protected void doGet(HttpServletRequest request, HttpServletResponse response)

StringBuffer sb = new StringBuffer();

for (int i = 0; i < ArrTmp.length; i++) {

sb.append(ArrTmp[i]);

}

String pwd = Encrypt(sb.toString());

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

System.out.println("pwd=="+pwd);
