PHP json 解析中的堆栈交换 api curl 操作问题

Question

我正在使用StackExchange获取项目的所有答案API。这样我就会点击网址 https://api.stackexchange.com/2.2/answers?page=10&pagesize=10&order=desc&sort=activity&site=stackoverflow在浏览器中点击原始json时显示，但问题是使用程序。

PHP
<?php 
//step1
$cSession = curl_init(); 
//step2
curl_setopt($cSession,CURLOPT_URL,"https://api.stackexchange.com/2.2/answers?page=10&pagesize=10&order=desc&sort=activity&site=stackoverflow");
curl_setopt($cSession,CURLOPT_RETURNTRANSFER,true);
curl_setopt($cSession,CURLOPT_HEADER, false); 
//step3
$result=curl_exec($cSession);
//step4
curl_close($cSession);
echo"<pre>";
var_dump($result);
echo "<br>";
echo"</pre>";
$jsonIterator = new RecursiveIteratorIterator(
    new RecursiveArrayIterator(json_decode($result, TRUE)),
    RecursiveIteratorIterator::SELF_FIRST);
foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:";
        echo"<br>";
    } else {
        echo "$key => $val";
        echo"<br>";
    }
}
?>

它像一些编码字符串一样显示结果，并给出解决方案。提前谢谢。

Answer 1

使用 '

gzdecode' 函数将从 GZIP JSON 解码

$ch = curl_init();
// Set the url
$url = "https://api.stackexchange.com/2.2/answers?page=10&pagesize=10&order=desc&sort=activity&site=stackoverflow";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_HEADER, false);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
// Will dump a beauty json :3
$result = gzdecode($result); // Here Decoding 
print_r($result);

我收到如下

{"items":[{"owner":{"reputation":1642,"user_id":6373435,"user_type":"registered", ... . . .

试试这个它对我有用使用终端检查此 URL，它显示编码格式：gzip。因此，我们需要使用以下行对其进行编码。

curl_setopt($cSession, CURLOPT_ENCODING, 'gzip');

完整代码=>

$cSession = curl_init(); 
//step2
curl_setopt($cSession,CURLOPT_URL,"https://api.stackexchange.com/2.2/answers?page=10&pagesize=10&order=desc&sort=activity&site=stackoverflow");
curl_setopt($cSession, CURLOPT_ENCODING, 'gzip');//--------->>> Solution step
curl_setopt($cSession,CURLOPT_RETURNTRANSFER,true);
//curl_setopt($cSession,CURLOPT_HEADER, false); 
//step3
$result=curl_exec($cSession);
//step4
curl_close($cSession);
echo"<pre>";
var_dump($result);
echo "<br>";
echo"</pre>";
