事先準備工作
	1.申請一個小程序,申請地址:傳送門
	2.仔細閱讀小程序的用戶授權登陸官方文檔: 《用戶授權登陸的流程》
	3.仔細閱讀微信用戶數據解密的相關文檔: 《用戶數據解密說明文檔》
	4.在小程序后臺配置好相應的后端請求地址,路徑是:開發---->開發設置,如圖
5.小程序如果需要做多個小程序的打通,還需要在微信開放平臺綁定到開發者賬號下面, 如果不需要union_id請忽略
6.服務端準備一個用戶授權的接口,假設接口鏈接為http://test.dev.com/user/authorization,此接口接受如下參數
接口返回的數據如下
{  "errcode": 200,  "msg": "SUCCESS",  "data": {    "uid": 34098,    "unionid": "xxx",  }}6.建表
1)用戶表,其中比較重要的字段是union_id,因為我們是有多個小程序和公眾號,因此使用這個來區分唯一的用戶編號
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 '用戶昵稱', `sex` enum('0','1') CHARACTER SET utf8 DEFAULT '1' COMMENT '性別', `avatar` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '用戶頭像', `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 '國家', `wx_union_id` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '公眾平臺的唯一id', `from_url` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '來源url', `created_at` timestamp NULL DEFAULT NULL, `updated_at` timestamp NULL DEFAULT NULL, `from_appid` varchar(30) COLLATE utf8mb4_unicode_ci DEFAULT 'wx95fc895bebd3743b' COMMENT '來源appid', `wx_header` varchar(150) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '微信頭像', `gh_openid` varchar(60) COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '微信公眾號openid', `phone` varchar(30) CHARACTER SET utf8 DEFAULT '' COMMENT '手機號碼', PRIMARY KEY (`id`), KEY `idx_uid_union_id` (`uid`,`wx_union_id`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;實現步驟

小程序端
小程序端的獲取用戶信息流程
	1)調用login方法獲取code
	2)調用getUserInfo方法獲取用戶的加密數據
	3)調用后端的用戶授權接口將用戶信息保存到服務端
	4)保存后端接口返回的uid和unionid到localstorage中,作為全局參數
獲取用戶的授權信息
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=" + 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)    }   }  }) },服務端
