为什么file_get_contents（）返回“无法打开流：HTTP请求失败！”？ HTTP/1.0 429未知

Question

我遇到了file_get_contents问题。我需要从这个网址获取内容：http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=P250%20|%20Valence%20(Field-Tested)

当我与我的浏览器中打开它的作品很好，我的PHP脚本：

$item = "P250 | Valence (Field-Tested)"; $link = 'http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name='.urlencode($item); echo file_get_contents($link);

抛出我这个错误：
Warning: file_get_contents(http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=P250+%7C+Valence+%28Field-Tested%29): failed to open stream: HTTP request failed! HTTP/1.0 429 Unknown

Answer 1

根据到错误消息，您从Steam的服务器接收到一个429 HTTP错误：

429 Too Many Requests (RFC 6585) 
The user has sent too many requests in a given amount of time. Intended for use with rate limiting schemes.
