Lumen/Laravel 中支付宝 / 微信第三方 App 登陆

介绍

现在几乎所有APP都集成了微信/支付宝登录,简化用户操作.这里介绍下在lumen/laravel中如何进行微信/支付宝APP登陆。

配置文件

config.woann.php 这里是我自己创建的配置文件,可以自行调整

<?php

return [
    //微信
    'wechat'    =>  [
        'app'   =>  [
            'appid'    =>  env('WECHAT_APPID', ''),
            'secret'    =>  env('WECHAT_APP_SECRET', '')
        ]
    ],
    //支付宝
    'alipay'    =>  [
        'app_id'        =>  env('ALI_APP_ID'),
        'pid'           =>  env('ALI_PID'),
        'private_key'   =>  env('ALI_PRIVATE_KEY')
    ]
];

支付宝登录基类

app/utility/AliPayLogin.php 这个文件随便你放哪里,能调用到即可

        }
        return $signStr;
    }
}

支付宝给客户端提供的两个接口

1.获取code字符串(客户端通过这个字符串获取code)

 public function aliLoginInfoStr()
    {
        $ali = new AliPayLogin();//实例化支付
        $res = $ali->infoStr();
        return returnApi(200,'SUCCESS',['str' => $res]);
    }
    /*
    数据示例
        {
        "code":200,
        "msg":"SUCCESS",
        "data":{    "str":"apiname=com.alipay.account.auth&method=alipay.open.auth.sdk.code.get&app_id=2021001100636235&app_name=mc&biz_type=openservice&pid=2088631756058087&product_id=APP_FAST_LOGIN&scope=kuaijie&target_id=44039&auth_type=AUTHACCOUNT&sign_type=RSA2&sign=EXMs+NtovsZEKxcwjprKYwIJIbdeESLYxI/cjyqQ1Re8st0ejTktkX06V+gnyTiwfi9KtdSXbM1HMuC8hGyCEeMZb0IDSyOmOXp+f2dDJDXdlzoqyVowOxn7enTejXnngmu2WDuKQo2KcWfRVBKFlnYyA42QOUYw0PEKiXsgJYdjNPyVqKH9oTJJWIASJgZOgXbY4LSDh8gP+P/5QsuM41fTggeeRLJYHNlvbFuigSF+KpdcPiXXi6huI+4NQpN/7PLzXbVHzdeipkHeYTV6tMZY4njv5RvE4UH9ESd3urpoCgRJxriR/mUdGdQZCDHIBKMXTHmagRXH8mx70SFdpA=="
        }
    }
    */

2.通过code获取用户信息进行登录

public function loginByAli(Request $request)
    {
        $code = $request->post('code');
        $ali = new AliPayLogin();//实例化支付宝登录基类
        $res = $ali->userInfo($code);//获取用户信息
        //....根据业务自行处理
    }

微信登录

1.微信通过code获取用户信息(供微信登录接口调用)

private function getUserInfoByWx($code)
    {
        $app = config('woann.wechat.app');//获取app_id,secret
        $auth_url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$app['appid']."&secret=".$app['secret']."&code=".$code."&grant_type=authorization_code";
        $auth_res = httpRequest($auth_url);
        if(isset($auth_res['errcode'])){
            return ['code' => $auth_res['errcode'], 'msg' => $auth_res['errmsg']];
        }
        $info_url = "https://api.weixin.qq.com/sns/userinfo?access_token=".$auth_res['access_token']."&openid=".$auth_res['openid']."&lang=zh_CN";
        $userinfo = httpRequest($info_url);
        if(isset($userinfo['errcode'])){
            return ['code' => $userinfo['errcode'], 'msg' => $userinfo['errmsg']];
        }
        return ['code' => 200, 'msg' => $userinfo];
    }

2.登陆接口

public function loginByWechat(Request $reques)
{
    $code = $request->post('code');
  $userInfo = $this->getUserInfoByWx($code);
    if ($userInfo['code'] != 200) {
        return returnApi($userInfo['code'], $userInfo['msg']);
    }
    //以下根据自己业务进行调整
    DB::beginTransaction();
    //根据openid查询用户是否存在
  $user = $this->where('wechat_openid', $userInfo['msg']['openid'])->first();
  if (!$user) {
        $user = new User();
        $user->avatar = $userInfo['msg']['headimgurl'];
        $user->nickname = $userInfo['msg']['nickname'];
        $user->sex = $userInfo['msg']['sex'];
        $user->wechat_openid = $userInfo['msg']['openid'];
    }
    $res = $user->save();
    if($res){
        if (!$token = Auth::login($user)) {
            DB::rollBack();
            return returnApi(500, '未知错误');
        } else {
            DB::commit();
            return returnApi(200, '登录成功', [
                'access_token' => 'Bearer '.$token
                ]);
        }
    }else{
        DB::rollBack();
        return returnApi(500,'未知错误');
    }
}
