微信小程序 : 用户登录

自动登录,只能在正式版时有用.体验版、开发版调用wx.getUserInfo 接口,将无法弹出授权询问框，默认调用失败。

var that = this;
wx.login({
  success: function (res) {
    var code = res.code;
    wx.getUserInfo({
      success: function (res) {
        //  用户数据保存
        var nickName = res.userInfo.nickName;
        var avatarUrl = res.userInfo.avatarUrl;
        var gender = res.userInfo.gender;
        if (code) {
          wx.request({
            url: 'login',
            data: {
              code: code,
              nick: nickName,
              avaurl: avatarUrl,
              sex: gender
            },
            header: {
              'content-type': 'application/json'
            },
            method: 'GET',
            success: function (res) {
              that.setData({
                user: res.data
              })
            }
          })
        }
      }
    })
  }
})
