Question

我正在从公司的IG提要中获取最新3个帖子的数据，并在我们的网站上对它们进行进一步处理，以用于IG小部件。

我已经进行了一些故障排除，看来问题是解码原始数据的json_decode部分。

这是从IG API获取的JSON数据：

{"pagination": {"next_max_id": "2034341501387371123_8393175932", "next_url": "https://api.instagram.com/v1/users/8393175932/media/recent?access_token=8393175932.65497a8.29744121571744afacbe375999b2525f\u0026count=1\u0026max_id=2034341501387371123_8393175932"}, "data": [{"id": "2034341501387371123_8393175932", "user": {"id": "8393175932", "full_name": "Coffea", "profile_picture": "https://scontent.cdninstagram.com/vp/e88d6cdddc5697515447cde6330b03ff/5D76FD6E/t51.2885-19/s150x150/38097055_446825915802974_1995256258839445504_n.jpg?_nc_ht=scontent.cdninstagram.com", "username": "coffea.earth"}, "images": {"thumbnail": {"width": 150, "height": 150, "url": "https://scontent.cdninstagram.com/vp/3b467c8e7913ecca2874fcbb055fd5b9/5D645F5D/t51.2885-15/e35/s150x150/59153051_2234956400103169_2351775859365829130_n.jpg?_nc_ht=scontent.cdninstagram.com"}, "low_resolution": {"width": 320, "height": 320, "url": "https://scontent.cdninstagram.com/vp/f34190b7534acd762f6435e12b3dd610/5D5E5025/t51.2885-15/e35/s320x320/59153051_2234956400103169_2351775859365829130_n.jpg?_nc_ht=scontent.cdninstagram.com"}, "standard_resolution": {"width": 640, "height": 640, "url": "https://scontent.cdninstagram.com/vp/8643e994a3a87ca8d93f25bcedd3ebf3/5D5FC6D8/t51.2885-15/sh0.08/e35/s640x640/59153051_2234956400103169_2351775859365829130_n.jpg?_nc_ht=scontent.cdninstagram.com"}}, "created_time": "1556732426", "caption": {"id": "17866442770374263", "text": "Coffee superpower \ud83d\udc4a\ud83d\udca5\nHundreds of millions of people all around the world drink coffee every day.

这是基本的PHP json_decode函数：

$latestpost_coded = file_get_contents("https://api.instagram.com/...&count=1");
$latestpost_data = json_decode($latestpost_coded);
$latestpost = $latestpost_data->data;

我已经确认这是使它变慢的代码的一部分。非常慢，例如10秒的加载时间。最初，该代码加载了3个最新帖子，但是3个结果的搜索结果和1个结果的搜索结果一样慢。

您应使用 cURL 而不是 file_get_contents（），因为在此讨论中，它确实会影响json_decode：

https://www.reddit.com/r/PHPhelp/comments/3hmxvs/json_decode_slow_af/

这是从其中一个答案中进行的cURL尝试：

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"#### YOUR URL GOES HERE ####");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $data = curl_exec ($ch);
    $json = json_decode($data,TRUE);
    // continue with normal json shit
curl_close ($ch);

Answer 2

最终，我通过每天半夜运行一次cron作业来获取IG API结果来解决该问题，将其保存到本地文件中，然后IG小部件正在使用此文件，该文件运行得很好。由于它只是IG预览窗口，因此对于我所需的结果而言是令人满意的。

问题似乎出在我们的托管服务器和IG服务器之间的通信错误。

CURL由于某种原因未能获取结果，而没有引发任何错误，因此该解决方案对我来说是死胡同。

Instagram API中的json_decode非常慢
