Laravel 中的“格式错误的 UTF-8 字符，可能编码不

问题描述

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.

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.

以下声明

return JsonResponse::create($data); 

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());
        }

我变了:

return JsonResponse::create($data);

到

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

但它仍然无法正常工作.

but it still isn't working.

我该如何解决?

推荐答案

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).

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

/**
 * 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);
