laravel的predis報錯亂碼

今天使用redis的時候報錯，但是頁面顯示一塌糊塌，原因是編碼錯誤。

Predis \ Connection \ ConnectionException (10061)
����Ŀ����������ܾ����޷����ӡ�

private function createExceptionMessage($message) {
    $encoding = mb_detect_encoding($message, array("ASCII", 'UTF-8', "GB2312", "GBK", 'BIG5'));
    // 如果字符串的編碼格式不爲UTF_8就轉換編碼格式，檢測代碼，檢測到是"EUC-CN"
    if ($encoding != 'UTF-8') {
        $message = mb_convert_encoding($message, 'UTF-8', $encoding);
    }
    #結束
    $parameters = $this->parameters;

    if ($parameters->scheme === 'unix') {
        return "$message [$parameters->scheme:$parameters->path]";
    }

    if (filter_var($parameters->host, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6)) {
        return "$message [$parameters->scheme://[$parameters->host]:$parameters->port]";
    }

    return "$message [$parameters->scheme://$parameters->host:$parameters->port]";
}
