在Laravel中，'格式错误的UTF-8字符，可能是错误编码的'

I'm using Laravel (a PHP framework) to write a service for mobile and have the data returned in JSON format. In the data result there are some fields encoded in UTF-8.

我正在使用Laravel（一个PHP框架）为移动设备编写服务，并以JSON格式返回数据。在数据结果中，有一些字段以UTF-8编码。

The following statement

以下声明

return JsonResponse::create($data);

returns the error below

返回以下错误

InvalidArgumentException
HELP
Malformed UTF-8 characters, possibly incorrectly encoded

Open: /var/www/html/vendor/symfony/http-foundation/Symfony/Component/HttpFoundation/JsonResponse.php
        } catch (\Exception $exception) {
            restore_error_handler();

            throw $exception;
        }

        if (JSON_ERROR_NONE !== json_last_error()) {
            throw new \InvalidArgumentException($this->transformJsonError());
        }

I've changed:

我改变了：

return JsonResponse::create($data);

至

return JsonResponse::create($data, 200, array('Content-Type'=>'application/json; charset=utf-8' ));

but it still isn't working.

但它仍然无法正常工作。

How can I fix it?

我该如何解决？

I wrote this method, to handle UTF8 arrays and JSON problems. It work fine with array (simple and multidimensional).

我编写了这个方法来处理UTF8数组和JSON问题。它适用于数组（简单和多维）。

/**
 * Encode array from latin1 to utf8 recursively
 * @param $dat
 * @return array|string
 */
   public static function convert_from_latin1_to_utf8_recursively($dat)
   {
      if (is_string($dat)) {
         return utf8_encode($dat);
      } elseif (is_array($dat)) {
         $ret = [];
         foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);

         return $ret;
      } elseif (is_object($dat)) {
         foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);

         return $dat;
      } else {
         return $dat;
      }
   }
// Sample use
// Just pass your array or string and the UTF8 encode will be fixed
$data = convert_from_latin1_to_utf8_recursively($data);

I found the answer to this problem here

我在这里找到了这个问题的答案

Just do

做就是了

mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');

#3

In my case, this causes error:

在我的情况下，这会导致错误：

return response->json(["message" => "Model status successfully updated!", "data" => $model], 200);

but this not:

但这不是：

return response->json(["message" => "Model status successfully updated!", "data" => $model->toJson()], 200);

#4

In my case I had a ucfirst on the asian letters string. This was not possible and produced a non utf8 string.

在我的情况下，我在亚洲字母字符串上有一个ucfirst。这是不可能的，并产生一个非utf8字符串。

This error also happens if you do not activate your Mysql database or Oracle etc ...

如果您不激活Mysql数据库或Oracle等，也会发生此错误...
