使用HTTP标头的Instagram API计数限制 [英] Instagram API count limits using HTTP header

问题描述

根据Instagram，您可以使用随呼叫提供的HTTP标头检查剩余的API限制计数。我对此很陌生，无法找到有关如何使用PHP访问此信息的相关数据。有人可以帮我解释一下吗？

According to Instagram you can check API limit count remaining using the HTTP headers that they supply with the call. I am quite new to this and am unable to find relevant data on how to access this information with PHP. Could anyone please clarify this for me?

我在Google网上论坛的Instagram API开发人员论坛上发现了以下内容：

I found the following from the Instagram API developers forum on Google Groups:

我们刚刚将其推广到生产;所有API调用现在都有
额外的HTTP标头：

• X-Ratelimit-Limit （每小时可能的电话总数）


• X-Ratelimit-Remaining （此特定令牌或客户ID的剩余电话数）

• X-Ratelimit-Limit (total # of possible calls per hour)
• X-Ratelimit-Remaining (how many calls are left for this particular token or client ID)"

推荐答案

如果你正在使用 file_get_contents 发出请求（或任何使用 HTTP包装器的任何内容），特殊变量 $ http_response_header 包含一系列行，其中包含最近请求的HTTP响应头。​​

If you're using file_get_contents to make the request (or anything that uses the HTTP wrapper for that matter), the special variable $http_response_header contains an array of lines with the HTTP response headers of the most recent request.

也许是这样的：

// Make your API request here
...
file_get_contents('http://example.com', false, $context);

// Check HTTP response headers
foreach ($http_response_header as $line) {
    if(preg_match('!X-Ratelimit-Remaining: ([0-9]+)!i', $line, $matches)) {
        $remaining = $matches[1];
        break;
    }
}

// Do something based on the number of remaining attempts
echo "Remaining attempts: $remaining";
