事先准备工作
1.申请一个小程序,申请地址:传送门
2.仔细阅读小程序的用户授权登陆官方文档: 《用户授权登陆的流程》
3.仔细阅读微信用户数据解密的相关文档: 《用户数据解密说明文档》
4.在小程序后台配置好相应的后端请求地址,路径是:开发---->开发设置,如图
5.小程序如果需要做多个小程序的打通,还需要在微信开放平台绑定到开发者账号下面, 如果不需要union_id请忽略
6.服务端准备一个用户授权的接口,假设接口链接为http://test.dev.com/user/authorization,此接口接受如下参数
- code:微信登陆接口返回的登陆凭证,用户获取session_key
- iv:微信小程序登陆接口返回的向量,用于数据解密
- encrypted_data : 微信获取用户信息接口的返回的用户加密数据,用于后端的接口解析
- signature加密数据
接口返回的数据如下
{ "errcode": 200, "msg": "SUCCESS", "data": { "uid": 34098, "unionid": "xxx", } }
6.建表
1)用户表,其中比较重要的字段是union_id,因为我们是有多个小程序和公众号,因此使用这个来区分唯一的用户编号
DROP TABLE IF EXISTS `jz_wxa_user`; CREATE TABLE `jz_wxa_user` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `uid` bigint(18) DEFAULT NULL, `openid` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT 'openid', `user_name` varchar(100) CHARACTER SET utf8mb4 DEFAULT '', `nick_name` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '用户昵称', `sex` enum('0','1') CHARACTER SET utf8 DEFAULT '1' COMMENT '性别', `avatar` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '用户头像', `province` varchar(100) CHARACTER SET utf8 DEFAULT NULL COMMENT '省份', `city` varchar(100) CHARACTER SET utf8 DEFAULT NULL COMMENT '城市', `country` varchar(100) CHARACTER SET utf8 DEFAULT NULL COMMENT '国家', `wx_union_id` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '公众平台的唯一id', `from_url` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '来源url', `created_at` timestamp NULL DEFAULT NULL, `updated_at` timestamp NULL DEFAULT NULL, `from_appid` varchar(30) COLLATE utf8mb4_unicode_ci DEFAULT 'wx95fc895bebd3743b' COMMENT '来源appid', `wx_header` varchar(150) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '微信头像', `gh_openid` varchar(60) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '微信公众号openid', `phone` varchar(30) CHARACTER SET utf8 DEFAULT '' COMMENT '手机号码', PRIMARY KEY (`id`), KEY `idx_uid_union_id` (`uid`,`wx_union_id`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
实现步骤
用户授权时序图
关键代码
小程序端
小程序端的获取用户信息流程
1)调用login方法获取code
2)调用getUserInfo方法获取用户的加密数据
3)调用后端的用户授权接口将用户信息保存到服务端
4)保存后端接口返回的uid和unionid到localstorage中,作为全局参数
获取用户的授权信息
getUid:function(cf){ var that = this wx.login({ success: function (ress) { var code = ress.code wx.getUserInfo({ withCredentials: true, success: function (res) { that.globalData.userInfo = res.userInfo; that.authorize(code, res.signature, res.iv, res.rawData, res.encryptedData, cf) } }) } }) }, authorize: function (code, signature, iv, rawData, encryptedData, cf) { var that =this var dataobj = { code: code, signature: signature, iv: iv, raw_data: rawData, encrypted_data: encryptedData } console.log("code:",code) var param = JSON.stringify(dataobj) param = that.Encrypt(param) var url = that.data.API_DOMAIN2 + "/user/authorization" + param wx.request({ url: url, method: "GET", header: { 'content-type': 'application/json' }, success: function (res) { if (res.data.errcode == 200) { wx.hideToast() wx.setStorage({ key: "uid", data: res.data.data.uid, success: function () { if (cf) { typeof cf == "function" && cf(res.data.data.uid) } } }) } else { that.exceptionHandle('uid', url, res.data.errcode, res.data.msg) } } }) },
