使用PHP从Stack Overflow API获取null作为响应

Question

我使用PHP代码来获得Stack Overflow的声誉.

$feed = json_decode(file_get_contents("http://api.stackexchange.com/2.1/users/22656?order=desc&sort=reputation&site=stackoverflow&filter=!*MxOyD8qN0Yghnep", true), true);
$array = $feed['items'][0];
$rep = $array['reputation'];
echo $rep;

但我得到null了饲料.此外,用户帐户是Jon Skeet,这是我获取ID 22656的地方.我该如何解决这个问题？

Answer 1

问题是响应也是gzip压缩.

我首选的修复方法是使用curl,使用CURLOPT_ENCODING选项.

<?php
function curl($url){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_TIMEOUT, 30);
    curl_setopt($curl, CURLOPT_USERAGENT, 'cURL');
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curl, CURLOPT_ENCODING , "gzip");//<< Solution

    $result = curl_exec($curl);
    curl_close($curl);

    return $result;
}


$feed = curl("http://api.stackexchange.com/2.1/users/22656?order=desc&sort=reputation&site=stackoverflow&filter=!*MxOyD8qN0Yghnep");

$feed = json_decode($feed,true);
$rep = $feed['items'][0]['reputation'];
echo $rep;//531776
?>

但是,您可以使用普通FGC,然后将响应膨胀回未压缩状态.

<?php
$feed = file_get_contents('http://api.stackexchange.com/2.1/users/22656?order=desc&sort=reputation&site=stackoverflow&filter=!*MxOyD8qN0Yghnep');
$feed = gzinflate(substr($feed, 10, -8));

$feed = json_decode($feed,true);
$rep = $feed['items'][0]['reputation'];
echo $rep;//531776
?>
