官方指引圖

按照官方引導(dǎo)圖一步一步操作

1、獲取code

1. onLoad: function (options) { // 頁面初始化 options為頁面跳轉(zhuǎn)所帶來的參數(shù) let that = this wx.login({ success: function (res) { // success let code = res.code that.setData({ code: code }) wx.getUserInfo({ success: function (res) { // success that.setData({ userInfo: res.userInfo }) that.setData({ iv: res.iv }) that.setData({ encryptedData: res.encryptedData }) that.get3rdSession() } }) } }) }

2、發(fā)送code到第三方服務(wù)器，獲取3rd_session

1. get3rdSession:function(){ let that = this wx.request({ url: 'https://localhost:8443/get3rdSession', data: { code: this.data.code }, method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT // header: {}, // 設(shè)置請求的 header success: function (res) { // success var sessionId = res.data.session; that.setData({ sessionId: sessionId }) wx.setStorageSync('sessionId', sessionId) that.decodeUserInfo() } }) }

3、在第三方服務(wù)器上發(fā)送appid、appsecret、code到微信服務(wù)器換取session_key和openid

這里使用JFinal搭建的服務(wù)器

Redis配置

1. public void configPlugin(Plugins me) { //用于緩存userinfo模塊的redis服務(wù) RedisPlugin userInfoRedis = new RedisPlugin("userInfo","localhost"); me.add(userInfoRedis); }

獲取第三方session

1. public void get3rdSession() { //獲取名為userInfo的Redis Cache對象 Cache userInfoCache = Redis.use("userInfo");
