laravel8+微信小程序静默登录

1.小程序app.js onLaunch（）方法中插入

let token = wx.getStorageSync(&＃39;token&＃39;)if (!token) {wx.login({success:ret=>{let code = ret.codewx.request({url: &＃39;http://www.zy.com/api/wxlogin&＃39;,method:"POST",data:{code},success:res=>{console.log(res.data);wx.setStorageSync(&＃39;token&＃39;, res.data.data)}})}})}

2.后台代码

/*** 微信静默登录*/public function wxLogin(Request $request){$code = $request->post(&＃39;code&＃39;);$appid = &＃39;**********&＃39;;$appSecret= &＃39;**********&＃39;;$url = "https://api.weixin.qq.com/sns/jscode2session?appid=$appid&secret=$appSecret&js_code=$code&grant_type=authorization_code";$res = json_decode(file_get_contents($url), true); //返回openid，session_key$getUserInfo = User::where(&＃39;openid&＃39;,$res[&＃39;openid&＃39;])->first();if ($getUserInfo) {$userId = $getUserInfo->id;} else {$create[&＃39;openid&＃39;] = $res[&＃39;openid&＃39;];$create[&＃39;session_key&＃39;] = $res[&＃39;session_key&＃39;];$result = User::create($create);$userId = $result->id;}$token=JwtService::createToken($userId);return [&＃39;code&＃39;=>200,&＃39;msg&＃39;=>&＃39;ok&＃39;,&＃39;data&＃39;=>$token];}
