easywechat微信开发系列（1）：公众号网页授权

准备工作：

1、已认证的服务号（apppid、appsecret、token、aes_key）

2、安全域名

3、已经用composer安装好easywechat

1、config/app.php 的 providers 数组，不用多说 

'providers' => [
    // ...
    Overtrue\LaravelWeChat\ServiceProvider::class,
],
'aliases' => [
    // ...
    'EasyWeChat' => Overtrue\LaravelWeChat\Facade::class,
],

2、发布资源

php artisan vendor:publish --provider="Overtrue\LaravelWeChat\ServiceProvider"

3、相关配置 config/wechat.php

'official_account' => [
        'default' => [
            'app_id' => env('WECHAT_OFFICIAL_ACCOUNT_APPID', '**'),         // AppID
            'secret' => env('WECHAT_OFFICIAL_ACCOUNT_SECRET', '**'),    // AppSecret
            'token' => env('WECHAT_OFFICIAL_ACCOUNT_TOKEN', '**'),           // Token
            'aes_key' => env('WECHAT_OFFICIAL_ACCOUNT_AES_KEY', '**'),                 // EncodingAESKey

            'oauth' => [
                 'scopes'   => array_map('trim', explode(',', env('WECHAT_OFFICIAL_ACCOUNT_OAUTH_SCOPES', 'snsapi_userinfo'))),
                 'callback' => env('WECHAT_OFFICIAL_ACCOUNT_OAUTH_CALLBACK', '/examples/oauth_callback.php'),
                 //'callback'=>'/'
             ],
        ],
    ],

4、在app\Http\Kernel.php 里面添加中间件

'wechat.oauth' => \Overtrue\LaravelWeChat\Middleware\OAuthAuthenticate::class,

5、路由中使用中间件

Route::get('user','HomeController@user')->middleware('wechat.oauth');

6、获取用户信息

$wechat = session('wechat.oauth_user.default');

7、补充：不用看

public function setUserInfo(){
         $wechat = session('wechat.oauth_user.default');
   
         $has = \App\Models\User::where('wxopenid', $wechat->id)->first();
        if(!$has){
            
            DB::beginTransaction();
            $result = DB::table('user')->insertGetId([
                'wxname' => $wechat->name,
                'wxopenid' => $wechat->id,
                'regIp'=> $ip = $_SERVER['REMOTE_ADDR'],
                'wxnickname'=>$wechat->nickname,
                'wxavatar'=>$wechat->avatar,
                'sex'=>$wechat->original['sex'],
                'wxcountry'=>$wechat->original['country'],
                'wxprovince'=>$wechat->original['province'],
                'wxcity'=>$wechat->original['city'],   
                'email'=>$wechat->email,
                'regType'=>'wx',
                'loginTime'=>'0',
                'created_at' => date('Y-m-d H:i:s'),
            'updated_at' => date('Y-m-d H:i:s'),
            ]);
            $bres = DB::table('balance')->insert(['version'=>0,'money'=>0,'user_id'=>$result]);
            if($result && $bres){
                DB::commit();
                $has = \App\Models\User::where('id',$result)->get();
            }else{
                DB::rollback();
                return redirect('/');
            }
            
        }else{
            $has->timestamps = false;
            $has->loginTime = $has->loginTime + 1;
            $has->save();
        }
        
        return $has;
    }
