使用Laravel将CSV文件上传到MySQL

Posted 2021-05-04

我正在尝试将一个csv文件上传到Laravel中的表users 。

这是我的php脚本：

private function _import_csv($path, $filename)
    {

        $csv = $path . $filename;
        $query = sprintf("LOAD DATA local INFILE '%s' INTO TABLE users FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '"' LINES TERMINATED BY '\n' IGNORE 0 LINES (`firstname`, `lastname`, `username`, `gender`, `email`, `country`, `ethnicity`, `education`  )", addslashes($csv));
    return DB::connection()->getpdo()->exec($query);

}



public function uploadUsers(){


    if (Input::hasFile('fileInput')){

        $file = Input::file('fileInput');
        $name = time() . '-' . $file->getClientOriginalName();

        $path = 'public/uploads/'.date('Y/m/');

        $file->move($path, $name);
        $this->_import_csv($path, $name);

    }

    return Response::json(["success"=>true]);
}

但是我收到了这个错误：

{"error":{"type":"ErrorException","message":"PDO::exec(): LOAD DATA LOCAL INFILE forbidden","file":"C:\wamp\www\lc2\laravel\app\controllers\UsersController.php","line":224}}

我不知道什么是错的。 有人可以帮帮我吗？

答案

请试一试

设置PDO连接选项

在database.php中设置属性PDO :: MYSQL_ATTR_LOCAL_INFILE

'mysql' => array(
            ....
            'options'    => [PDO::MYSQL_ATTR_LOCAL_INFILE=>true],
        ),

另一答案

尝试在sprintf函数之前清理查询字符串。
