Trying to grab a json file to cache it locally

本文关键字：缓存抓取 json 文件 | 更新日期: 2023-09-27

<?php
$json_url = 'https://api.feedbin.me/v2/entries.json';
$username = 'username';  // authentication
$password = 'password';  // authentication
$ch = curl_init( $json_url );
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_USERPWD => $username . ":" . $password   // authentication
);
// Setting curl options
curl_setopt_array( $ch, $options );
$result =  curl_exec($ch); // Getting JSON result string
$cache_feedbin = '/BLAH/'.sha1($result).'.json';
    if(file_exists($cache_feedbin) && filemtime($cache_feedbin) > time() - 1000){
        // if a cache file newer than 1000 seconds exist, use it
        $data_feedbin = file_get_contents($cache_feedbin);
    } else {
        $data_feedbin = file_get_contents($result);
        file_put_contents($cache_feedbin,json_encode($data_feedbin));
    }
    foreach (array_slice(json_decode($data_feedbin), 0, 5) as $obj) {
        $feedbin_title = $obj->title;
        $feedbin_url = $obj->url;
        echo '<li><a href="', $feedbin_url, '">', $feedbin_title, '</a></li>';
    }
?>

为什么我得到"假"在本地缓存的json?json_encode是错误的吗?

尝试在curl选项中禁用证书验证:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

你可以查看curl错误的细节:

curl_error($ch)

…这可能会报告证书验证问题。
