如何在PHP中使用Stack Overflow API [英] How to use Stack Overflow API in PHP

问题描述

我有以下网址:

https://api.stackexchange .com/2.0/questions?page = 1& pagesize = 30& order = desc& sort = activity& site = stackoverflow

当我在浏览器的地址栏中键入该URL时，它会给我一个JSON响应，这在PHP中是必需的.我尝试使用cURL来获取它(请参见下面的代码)，但是它不起作用—没有响应打印在页面上.

When I type this URL in my browser's address bar, it gives me a JSON response, which I need in PHP. I tried using cURL to fetch it (see below code), but it didn't work — no response is printed on the page.

function get_json($url) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $url);

    $data = curl_exec($ch);
    $resultCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    if ($resultCode == 200) {
        return json_decode($data);
    } else {
        return false;
    }
}

$json = get_json('https://api.stackexchange.com/2.0/questions?page=1&pagesize=30&
  key=VVq3kJHSjQ*7qgpiRaVoLA%28%28&site=stackoverflow');
echo '<pre>';
print_r($json);

如何获取此URL并将其正确转换为PHP数组?

How can I fetch this URL and convert it into a PHP array the right way?

推荐答案

最后我检查了一下，API的所有响应均经过gzip压缩:

Last I checked, all responses from the API were gzip'd:

$ch = curl_init();
curl_setopt_array($ch, array(
    CURLOPT_URL => $url
  , CURLOPT_HEADER => 0
  , CURLOPT_RETURNTRANSFER => 1
  , CURLOPT_ENCODING => 'gzip'
));
$data = curl_exec($ch);
var_dump($data);
var_dump(json_decode($data));

设置CURLOPT_ENCODING可以使响应自动解压缩，除了在http请求中发送Accept-Encoding: gzip之外，尽管发送该标头并非严格要求，但可以正常工作.

Setting CURLOPT_ENCODING enables automatic un gzip'ing of the response, in addition to sending an Accept-Encoding: gzip in the http request, although sending that header isn't strictly required for this to work.
