小程序端

      login: function (e) {
        var that = this;
        wx.login({
          success: function (res_) {
            that.setData({
              session: res_.code,
            })
          }
        })
        wx.getUserProfile({
          desc: '用于完善會員資料', // 聲明獲取用戶個人信息后的用途，后續(xù)會展示在彈窗中，請謹慎填寫
          success: (res) => {
            var url = 'User/getUser'
            var params = { 
              js_code: that.data.session, 
              openid: app.globalData.openid,
              iv: res.iv,
              encryptedData: res.encryptedData,
              // 修正
              // nickname: e.detail.userInfo.nickName,
              // head: e.detail.userInfo.avatarUrl
            }
            util.wxRequest(url, params, data => {
              if (data.code == 200) {
                app.globalData.userInfo = data.data
                app.globalData.login = true
                this.setData({ login:true })
                wx.showToast({
                  title: '登錄成功',
                  icon: 'success',
                  duration: 2000
                })
              } else {
                //錯誤，需用戶重新授權(quán)登錄
                app.globalData.login = false
                wx.showToast({
                  title: data.msg,
                  icon: 'none',
                  duration: 2000
                })
              }
            }, data => { }, data => { })
          }
        })
      },

以上代碼大致流程為:

1.在小程序界面點擊按鈕發(fā)送js_code與encryptedData和iv到自己的服務(wù)器

2.服務(wù)器接收到j(luò)s_code后配合appid與secret共同調(diào)用微信接口獲取session_key與openid

3.使用獲取到的encryptedData與iv以及獲取到的session_key進行解密,將返回的數(shù)據(jù)轉(zhuǎn)化為數(shù)組,提取其中的nickName與avatarUrl

4.連接服務(wù)器,將openid,nickName,avatarUrl,存入數(shù)據(jù)庫之中文章來源地址http://www.zghlxwxcb.cn/news/detail-509931.html
