微信小程序授权认证标准实现

  在微信小程序开发过程中，获取用户微信认证并且按照微信调用流程实现的一套标准化的代码,实现了微信登录获取用户信息等一系列的调用过程。

  userLogin() {
    var that = this;
    wx.login({
      success(res) {
        if (res.code) {
          //发起网络请求
          wx.request({
            url: app.globalData.BASE_REQUEST_URL + '/wx/api/login',
            data: {
              code: res.code
            },
            header: {
              'content-type': 'application/json' // 默认值
            },
            success: function (res) {
              console.log(res);
              var userinfo = {};
              userinfo['openid'] = res.data.data.openid;
              userinfo['session_key'] = res.data.data.session_key;
              userinfo['unionid'] = res.data.unionid;
              wx.setStorageSync('userinfo', userinfo);

              var opid = res.data.data.openid;
              var unid = res.data.data.unionid;
              // An highlighted block
              wx.showModal({
                title: '温馨提示',
                content: '正在请求您的个人信息',
                success(res) {
                  if (res.confirm) {
                    wx.getUserProfile({
                      desc: "获取你的昵称、头像、地区及性别",
                      success: res => {
                        var wxUserInfo = res.userInfo;
                        wxUserInfo.openid=opid;
                        wxUserInfo.unionid=unid;
                        wxUserInfo.idCard = "622102199501083817"
                        wxUserInfo.ltRealName = "倪辉"
                        wxUserInfo.phone = "186020643707"
                        wx.request({
                          url: app.globalData.BASE_REQUEST_URL + '/wx/api/register',
                          method:"POST",
                          data: wxUserInfo,

                            'content-type': 'application/json' // 默认值
                          },
                          success:function(res){
                            console.log("注册成功")
                            that.setData({
                              userInfo:res.data.data,
                              hasUserInfo: true
                            })
                            wx.setStorageSync("AppUsers",res.data.data)
                          }
                        })

                      },
                      fail: res => {
                        //拒绝授权
                        // wx.showErrorModal('您拒绝了请求');
                        wx.showToast({

                          icon: "none"
                        })
                        return;
                      }
                    })
                  } else if (res.cancel) {
                    //拒绝授权 showErrorModal是自定义的提示
                    wx.showToast({

                  }
                }
              })
            }
          })
        } else {
          console.log('登录失败！' + res.errMsg)
        }
      }

  },

后端实现
