29.                                         let data = res.data; 
30.                                         if (res.statusCode === 200) { 
31.                                             swan.setStorageSync('Token', data.token); 
32.                                             swan.setStorageSync('userInfo', data.data); 
33.                                             swan.navigateBack(); 
34.                                             swan.showToast({

37.                                                 duration: 1000, 
38.                                             }); 
39.                                         } 
40.                                     } 
41.                                 }) 
42.                             } 
43.                         }) 
44.                     }, 
45.                     fail(err) { 
46.                         swan.showToast({ 
47.                             title: '授权失败' 
48.                         }); 
49.                     } 
50.                 }); 
51.             }, 
52.             fail: function (err) { 
53.                 console.log('登录失败', err); 
54.             } 
55.         }); 

说明：
（1）小程序用户首次访问，授权成功后用户信息会同步到后台“会员中心”，使用之前必须先在member表添加openid字段
（2）如果用户是登录用户，会同步更新会员中心登录状态，
（3）微信小程序由于官方现在，无法获取用户真实头像和用户昵称了
