1.小程序端代码
var app = getApp();var url = ‘http://shzujune.com/mianya/public/index/index/wxlogin‘;var login = function (code, encrypteData, iv) { var that = this //创建一个dialog提示 wx.showToast({ title: ‘正在登录...‘, icon: ‘loading‘, duration: 5000 }); wx.request({ url: url, method: ‘get‘, data: { code: code, encrypteData: encrypteData, iv: iv }, header: { ‘Content-Type‘: ‘application/json‘ }, success: function (res) { wx.hideToast() //console.log(‘服务器返回‘ + res.data) app.globalData.userInfo = res.data }, fail: function () { wx.showToast({ title: ‘网络错误!‘, duration: 2000 }) }, complete: function () { } })}Page({ data: { //判断小程序的API,回调,参数,组件等是否在当前版本可用。 canIUse: wx.canIUse(‘button.open-type.getUserInfo‘) }, onLoad: function () { var that = this wx.login({ success: function (res) { //登录成功 //console.log(res) if (res.code) { var code = res.code wx.getUserInfo({ //getUserInfo流程 success: function (data) { //getUserInfo获取用户信息成功 //console.log(data) //encrypteData加密密文,iv偏移向量,encodeURIComponent把加密字符串解密成URI字符串 var encryptedData = encodeURIComponent(data.encryptedData); var iv = data.iv; //请求自己的服务器 login(code, encryptedData, iv); //已经授权的用户 wx.switchTab({ url: ‘../rec/rec‘, }) } }) } else { console.log(‘用户没有进行授权!‘ + res.errMsg) } } }); }, bindGetUserInfo: function (e) { //console.log(e) if (e.detail.userInfo) { //用户按了允许授权的按钮 var that = this wx.login({ success: function (res) { if (res.code) { var code = res.code wx.getUserInfo({ success: function (data) { var encryptedData = encodeURIComponent(data.encryptedData); var iv = data.iv; //请求自己的服务器 login(code, encryptedData, iv); } }) } } }) //授权成功后,跳转进入小程序首页 wx.switchTab({ url: ‘../rec/rec‘ }) } else { //用户按了拒绝按钮 wx.showModal({ title: ‘警告‘, content: ‘您点击了拒绝授权,将无法进入小程序,请授权之后再进入!!!‘, showCancel: false, confirmText: ‘返回授权‘, success: function (res) { if (res.confirm) { console.log(‘用户点击了“返回授权”‘) } } }) } },})
2.php 端代码
<?phpnamespace appteacherapicontroller;use thinkController;/*** @date: 2018-12* 微信操作类*/class WxDecode extends Controller{ public function httpGet($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; } /** * @author: zxf * @date: 2018-12-08 * @description: 解密微信用户敏感数据 * @return array */ public function WxDecode() { // 接收参数 $data = request() -> param(); // 引入解密文件 在微信小程序开发文档下载 vendor(‘wx.WXBizDataCrypt‘); vendor(‘wx.ErrorCode‘); $appid = config(‘TESTPPID‘); $appsecret = config(‘TESTSECREET‘); $grant_type = "authorization_code"; //授权(必填) $code = $data[‘code‘]; //有效期5分钟 登录会话 $encryptedData=$data[‘encryptedData‘]; $iv = $data[‘iv‘]; $signature = $data[‘signature‘]; $rawData = $data[‘rawData‘]; // 拼接url $url = "https://api.weixin.qq.com/sns/jscode2session?"."appid=".$appid."&secret=".$appsecret."&js_code=".$code."&grant_type=".$grant_type; $res = json_decode($this->httpGet($url),true); $sessionKey = $res[‘session_key‘]; //取出json里对应的值 $signature2 = sha1(htmlspecialchars_decode($rawData).$sessionKey); // 验证签名 if ($signature2 !== $signature){ return json("验签失败"); } // 获取解密后的数据 $pc = new WXBizDataCrypt($appid, $sessionKey); $errCode = $pc->decryptData($encryptedData, $iv, $data ); if ($errCode == 0) { return return_succ($data); } else { return return_error($errCode); } }}
