Twitch API 使用 PHP 时出现连接错误

Question

我的英语水平很差。如果我犯了错误，我很抱歉。我正在尝试通过 php 连接 twitch api，但出现错误。

<?php
 $json=@json_decode(file_get_contents("https://api.twitch.tv/kraken/streams/artemis"));
 $json->display_Name;
?>

请帮我解决一下，谢谢。

Answer 1

您需要深入了解响应树。您要找的属性在 stream->channel 中。要得到它就去做

echo $json->stream->channel->display_name

Answer 2

这应该有效：

$json=json_decode(file_get_contents("https://api.twitch.tv/kraken/streams/artemis"));
$json->stream->channel->display_name;

检查$json的var_dump是对象的对象:
