php의 file_get_contents가 xkcd에서 json 파일을 잘못 검색하는 이유는 무엇입니까?

Question

xkcd 만화를 다운로드하기 위해 PHP 스크립트를 작성하면서 특정 만화책을 얻으 려 할 때 오류가 발생했습니다 (최신 버전과 반대). 특히, 다음 URL에서 file_get_contents를 가리키는 :

xkcd.com/$COMIC_NUM/info.0.json

는 알수없는 XHTML의 xkcd.com에 만화의 페이지 버전이 아닌 JSON 파일을 검색. 그러나 브라우저에서 정확히 동일한 URL을 요청하면 올바른 JSON 파일이 다운로드됩니다. 왜 이런 일이 일어나고 있는지 모르겠지만 요청 헤더가 전송되는 것과 관련이 있다고 생각됩니다.

도와주세요! : 그것은 개인적으로 나를 위해 file_get_contents와 함께 완벽하게 작동 I 하다니 S

Answer 1

, 당신은 다음과 같이 cURL를 사용하여 시도 할 수이보다 강력한 솔루션이 될 것처럼 (당신은 그것을 사용할 수있는 경우) :

<?php 
    $COMIC_NUM = 849; 

    $curlSession = curl_init(); 
    curl_setopt($curlSession, CURLOPT_URL, '"http://xkcd.com/'.$COMIC_NUM.'/info.0.json'); 
    curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true); 
    curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true); 
    $jsonData = curl_exec($curlSession); 
    curl_close($curlSession); 

    echo($jsonData); 
?> 

Answer 2

작품 벌금 나를. 어쩌면 $COMIC_NUM이 제대로 설정되지 않았습니까?

php > echo file_get_contents('http://xkcd.com/847/info.0.json');
