InvalidArgumentException：格式错误的UTF-8字符，可能在文件中编码不正确-Laraval

问题描述

返回Std类类型对象时，显示错误。我正在使用PHP 7和Laravel 7.0

错误从JsonResponse.php的setData函数返回（Illuminate \ Http） 使用DEFAULT_ENCODING_OPTIONS = 15的setData函数。这就是该问题的原因

我无法解决此问题，但是我尝试将JsonResponse setData方法$this->encodingOptions更改为JSON_UNESCAPED_UNICODE | JSON_INVALID_UTF8_IGNORE。

现在，错误已解决。但是我需要另一种解决方法。

public function setData($data = [])
{
    $this->original = $data;

    if ($data instanceof Jsonable) {
        $this->data = $data->toJson($this->encodingOptions);
        //$this->data = json_encode($data->jsonSerialize(),JSON_UNESCAPED_UNICODE | JSON_INVALID_UTF8_IGNORE);  // LINE NO: 01

    } elseif ($data instanceof JsonSerializable) {

        $this->data = json_encode($data->jsonSerialize(),$this->encodingOptions);
        //$this->data = json_encode($data->jsonSerialize(),$this->encodingOptions);  // LINE NO: 02

    } elseif ($data instanceof Arrayable) {

        $this->data = json_encode($data->toArray(),$this->encodingOptions);
    } else {
        $this->data = json_encode($data,$this->encodingOptions);
        //$this->data = json_encode($data,JSON_UNESCAPED_UNICODE | JSON_INVALID_UTF8_IGNORE);  // LINE NO: 03

    }

    if (!$this->hasValidJson(json_last_error())) {
        throw new InvalidArgumentException(json_last_error_msg());
    }

    return $this->update();
}

取消注释行1,2,3错误已解决！ 我需要另一种方法来解决此问题。因为在运行后，composer安装了该更改，因此... 这是我检索json的一部分
