如何解析TwitchTV Api？

Question

$json = file_get_contents('https://api.twitch.tv/kraken/streams');
$jsonDecoded = json_decode($json);

$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($jsonDecoded));
fclose($fp);

我只需要https://api.twitch.tv中的2个字段。

这是stream-＆gt; channel-＆gt; name和streams-＆gt;观众;

我如何为每个建筑创造好处？

Answer 1

你可以简单地迭代它并像这样复制：

$streams = array();
foreach ($jsonDecoded->streams as $stream) {
    $streams[$stream->channel->display_name] = $stream->viewers;
}

然后你就可以像使用其他键一样操作key =＆gt; value php array，ie。：

foreach ($streams as $stream => $viewers) {
    echo $stream.": ".$viewers."\n";
}

Answer 2

foreach ($jsonDecoded->streams as $stream) {
    $streams[$stream->channel->display_name] = $stream->viewers;
}

这对我不起作用。我不得不将其更改为此工作：

foreach ($jsonDecoded->streams as $stream) {
    $streams[$stream->channel->display_name] = $stream->viewers;
}
