Laravel 5在有效文件类型上验证CSV文件错误 [英] Laravel 5 validate csv file error on valid file type

问题描述

我正在尝试使用验证上传的csv文件

I am trying to validate an uploaded csv file with

$validator = Validator::make(
        [
            'file'      => $file,
            'extension' => strtolower($file->getMimeType()),
        ],
        [
            'file'      => 'required|in:csv',
        ]
    );

验证器无法提供带有消息The file must be a file of type: csv.

The validator fails on giving a valid csv file with message The file must be a file of type: csv.

如果我删除in:csv，则验证程序通过.

The validator passes if i remove in:csv.

我做错什么了吗?

PS-$file可用，并且具有标准上传文件类型object(Symfony\Component\HttpFoundation\File\UploadedFile)

PS - $file is available and of standard upload file type object(Symfony\Component\HttpFoundation\File\UploadedFile)

推荐答案

        'file'      => 'required|in:csv',
    ]
);
