Laravel“格式错误的UTF-8字符，可能编码有误"，该如何解决? [英] Laravel "Malformed UTF-8 characters, possibly incorrectly encoded", how to fix?

问题描述

我尝试将通过用户模型中的以下方法获得的json添加的属性返回，但我不断获得

I try to return as json added attribute which I get with the following method in my User model but I keep getting

 "message": "Malformed UTF-8 characters, possibly incorrectly encoded",
    "exception": "InvalidArgumentException",
    "file": "/var/www/timetool/vendor/laravel/framework/src/Illuminate/Http/JsonResponse.php",

代码

   /**
     * @return string
     */
    public function getAvatarImageAttribute($value)
    {

        if($this->hasMedia('avatar')) {
             $image = $this->getMedia('avatar');
             $img = \Intervention\Image\ImageManagerStatic::make($image[0]->getPath())->encode('data-url');
         }
         elseif (isset($this->blob->dokument)) {
             $img = 'data:image/jpeg;base64,'. base64_encode($this->blob->document);
         } else {
             $img = '';
         }

         return $img;
    }

在控制器中，我有

return \Response::json($users, 200, array('Content-Type' => 'application/json;charset=utf8'), JSON_UNESCAPED_UNICODE);

推荐答案

我认为这与仅需要UTF8字符的JSON有关，并且您的Blob可能包含无效的字符.尝试utf8_encode($ img). http://at2.php.net/manual/en/function. utf8-encode.php 在您的控制器中只需返回即可. Laravel将为您建立一个适当的json响应.

I'm thinking it's related to JSON needing only UTF8 chars and your blob may have invalid chars. Try utf8_encode($img). http://at2.php.net/manual/en/function.utf8-encode.php In your controller just return. Laravel will build a proper json response for you.
