java开发微信分享到朋友圈功能

微信分享功能开发

用了一天时间，把微信发送给朋友和分享到朋友圈功能开发出来，在这里给大家分享一下，避免大家走弯路。

一、服务器端程序

package com.wiimedia.controller;


import java.io.IOException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.google.gson.Gson;
import com.wiimedia.model.Ticket;
import com.wiimedia.service.ArticleSolrService;
import com.wiimedia.service.TicketRepository;
import com.wiimedia.service.TicketRepositorySolr;
import com.wiimedia.utils.GetRandomStr;
import com.wiimedia.utils.SignatureBean;
import com.wiimedia.utils.weixin.WeixinUtil;


@Controller
@RequestMapping("/WeixinshareController/Api/Inteface")

  HttpServletResponse response) throws IOException, ParseException{
 //获取签名页面链接
 String url = request.getParameter("url");

 //从数据库中获取标签，并检查标签是否过期
 Ticket oldticket = ticketRepositorySolr.getTicketById("20160114wiimediamrylsong1152");
 if(oldticket==null){//第一次访问，标签不存在。
  executeTicket(response,"1",url,format);
  return null;
 }else{//标签存在，判断标签是否超时
  String oldAcquiretime = oldticket.getAcquiretime();
  long difference=format.parse(format.format(new Date())).getTime()-format.parse(oldAcquiretime).getTime();
  if(difference>7100000){//标签超时,重新到微信服务器请求标签超时时间为7200秒（7200000毫秒）
  executeTicket(response,"2",url,format);
  return null; 
  }else{//标签未超时
  
  String signature = signature(oldticket.getTicket(),oldticket.getTimestamp(),oldticket.getNoncestr(),url);
  SignatureBean signatureBean = new SignatureBean();
  signatureBean.setNoncestr(oldticket.getNoncestr());

  } 
 }


 }

 ticket.setTid("20160114wiimediamrylsong1152");
 ticket.setAcquiretime(acquiretime);
 ticket.setTimestamp(timestamp);
 ticket.setNoncestr(noncestr);
 //因为用的SOLR所以更新和添加的方法是一样的，可以根据自己具体需求进行修改，本文不再贴出代码.
 if(flag.equals("2")){
  ticketRepositorySolr.addTicketToSolr(ticket);

 response.getWriter().print(new Gson().toJson(signatureBean));
 }

 
 private String signature(String jsapi_ticket, String timestamp, String noncestr, String url) {
 jsapi_ticket = "jsapi_ticket=" + jsapi_ticket;
 timestamp = "timestamp=" + timestamp;
 noncestr = "noncestr=" + noncestr;

 String[] arr = new String[] { jsapi_ticket, timestamp, noncestr, url };
 // 将token、timestamp、nonce,url参数进行字典序排序
 Arrays.sort(arr);

  }
 }
 MessageDigest md = null;
 String tmpStr = null;

 try {
  md = MessageDigest.getInstance("SHA-1");
  // 将三个参数字符串拼接成一个字符串进行sha1加密

 }


 class ShareAccess_Token{
 private String access_token;
 private String expires_in;
 public String getAccess_token() {
  return access_token;
 }
 public void setAccess_token(String accessToken) {
  access_token = accessToken;
 }
 public String getExpires_in() {
  return expires_in;
 }
 public void setExpires_in(String expiresIn) {

 }

 }
}

二、客户端代码.
