Question

我试图通过curl从网站上获取信息。使用class API { function get_curl_content($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_HEADER, false); $result = curl_exec($curl); curl_close($curl); return $result; } const CACHE_KEY = 'rate'; public static function getRate() { if (Cache::has(self::CACHE_KEY)) { return Cache::get(self::CACHE_KEY); } $oneHourTimestamp = \Carbon\Carbon::now()->addHours(1); $tenMinutesTimestamp = \Carbon\Carbon::now()->addMinutes(10); $result = $this->get_curl_content('https://example.com/'); $rates = json_decode($result, TRUE); if (!$rates) { Cache::put(self::CACHE_KEY, '-', $tenMinutesTimestamp); return '-'; } $Rate = @$rates['1']['2']; if (!$Rate) { Cache::put(self::CACHE_KEY, '-', $tenMinutesTimestamp); return '-'; } Cache::put(self::CACHE_KEY, $Rate, $oneHourTimestamp); return $Rate; } }不是一个选项，因为在服务器上已禁用。所以目前的来源就是这个

roduction.ERROR: Symfony\Component\Debug\Exception\FatalErrorException: Uncaught TypeError: Argument 1 passed to Illuminate\Exception\PlainDisplayer::display() must be an instance of  Exception, instance of Error given, called in    /var/www/vendor/laravel/framework/src/Illuminate/Exception/Handler.php on line 280 and defined in /var/www/vendor/laravel/framework/src/Illuminate/Exception/PlainDisplayer.php:15

当我执行此操作时，我在laravel.log中遇到错误

<?php

function get_curl_content($url) {
       $curl = curl_init();
       curl_setopt($curl, CURLOPT_URL, $url);
       curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
       curl_setopt($curl, CURLOPT_HEADER, false);
       $result = curl_exec($curl);
       curl_close($curl);
       return $result;
}



$urldata = get_curl_content('https://example.com/');

echo $urldata;

这里有什么问题？
