php – 在Laravel中’格式错误的UTF-8字符,可能错误编码’

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.

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());
        }

我改变了：

return JsonResponse::create($data);

至

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

但它仍然无法正常工作.

我该如何解决？

解决方法:

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);
