[PHP知识库]laravel7.* 七牛云存储+图片审核+文字审核

1. composer 下载

composer require zgldh/qiniu-laravel-storage

2. 配置文件（在?config下的app.php?加上）

zgldh\QiniuStorage\QiniuFilesystemServiceProvider::class

接下来在config/filesystems.php里的disks中新增如下选项：

'disks' => [
        ... ,
        'qiniu' => [
            'driver'  => 'qiniu',
            'domains' => [
                'default'   => 'laravelacademy.com1.z0.glb.clouddn.com', //你的七牛域名
                'https'     => 'dn-laravelacademy.qbox.me',         //你的HTTPS域名
                'custom'    => 'static.laravelacademy.org',     //你的自定义域名
             ],
            'access_key'=> '',  //AccessKey
            'secret_key'=> '',  //SecretKey
            'bucket'    => '',  //Bucket名字
            'notify_url'=> '',  //持久化处理回调地址
        ],
    ],

3.控制器实现

 /*

     * */
    public function upImage(request $request){
        //图片审核
        $fileTmp = $request->file('image')->getPathname();
       $result =  $this->imageAudit($fileTmp);
       if($result['conclusion'] != "合规") return json_encode(['code'=>400,',msg'=>"文件不合规"]);
       var_dump($result);
       //云存储
        $disk = Storage::disk('qiniu'); //使用七牛云上传
        $time = date('Y/m/d/H-m-s');
        $file     = $request->file('image');
        $filePath = $file->getRealPath();
        $ext = $file->getClientOriginalExtension();
        $filename = $disk->put($time.'.'.$ext, file_get_contents($filePath));//上传
        //图片地址
        $url = 'http://liyan.shop'.$time.'.'.mt_rand(1000,9999).$ext;
        if(!$filename) return json_encode(['code'=>400,'msg'=>"文件错误"]);
        return json_encode(['code'=>200,'msg'=>"文件上传成功",'data'=>$url]);
    }


    public function contentAudit(Request $request)
    {
        //审核的内容
        $content = $request['content'];
        $token = $this->getAccessToken('apikey', 'secrekey');
        $url = 'https://aip.baidubce.com/rest/2.0/solution/v1/text_censor/v2/user_defined?access_token=' . $token;
        $bodys = array(

        );
        $res = $this->curlPost($url, $bodys);
        //结果转成数组
        $res = json_decode($res, true);
        //根据自己的业务逻辑进行处理
        return $res;
    }

        return $res;
    }

    /**
     * CURL的Post请求方法
     * @param string $url
     * @param string $param
     * @return bool|string
     */
    function curlPost($url = '', $param = '')

        curl_setopt($curl, CURLOPT_HEADER, 0);

        // 运行curl
        $data = curl_exec($curl);
        curl_close($curl);

        return $data;
    }
