Twitch API - 要求授权令牌不返回任何内容

Question

我有类似的问题：Twitch API - can't get auth token using PHP 但不能写评论。

试了代码：

    $ch = curl_init("https://api.twitch.tv/kraken/oauth2/token");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
$fields = array(
    'client_id' => 'blablabla_correct',
    'client_secret' => 'blablabla_also_correct',
    'grant_type' => 'authorization_code',
    'redirect_uri' => 'http://localhost/php/twitch.php',
    'code' => $_GET['code']
);


 curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    $data = curl_exec($ch);
print $data;

但它什么也没打印。所以我尝试使用#2中的代码调试请求：

// to start, just use the code you've already got:
$ch = curl_init("https://api.twitch.tv/kraken/oauth2/token");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
$fields = array(
    'client_id' => 'blablabla_correct',
    'client_secret' => 'blablabla_also_correct',
    'grant_type' => 'authorization_code',
    'redirect_uri' => 'http://localhost/php/twitch.php',
    'code' => $_GET['code']
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$data = curl_exec($ch);

// Now, here we believe the first error comes into play, so let's check it out
print_r($data); // confirm that this is not what we want
$info = curl_getinfo($ch); // let's get some details about that last request
// print it out and see what we get
echo '<pre>';
print_r($info);
echo '</pre>';

我得到以下数组。我不知道下一步该做什么。 API 文档在这里：https://github.com/justintv/Twitch-API/blob/master/authentication.md#auth-code

Answer 1

我可能是错的，但作为其他登录提供商，我可以想象 twitch 也不允许 redirect urls 访问不存在的域，例如 localhost。

如果你想要 localhost 返回 url，我可以更喜欢这个服务，你可以将你的重定向 url 指向一个通配符服务器，并且请求被重定向到你的 localhost。

http://xip.io

xip.io 是一个神奇的域名，可为任何 IP 提供通配符 DNS 地址。假设您的 LAN IP 地址是 10.0.0.1。使用 xip.io，

     10.0.0.1.xip.io            resolves to   10.0.0.1
     www.10.0.0.1.xip.io        resolves to   10.0.0.1    
     mysite.10.0.0.1.xip.io     resolves to   10.0.0.1  
     foo.bar.10.0.0.1.xip.io    resolves to   10.0.0.1
