php - Json 解码 Twitch Api PHP

Question

我正在尝试获取 twitch tv 的 Json Decoded 字符串的适当性

$hue = file_get_contents('https://api.twitch.tv/kraken/streams/?channel=starladder1');
$hue = json_decode($hue);
print_r($hue->display_name);

但它不起作用几乎所有东西都试了请帮忙

Answer 1

试试下面的代码：

<?php
    $hue = file_get_contents('https://api.twitch.tv/kraken/streams/?channel=starladder1');

    $hue1 = json_decode($hue, TRUE);

     foreach ($hue1 as $data)
        {
         foreach ($data as $datas) {

        echo ($datas['channel']['display_name']."<br/>");

             }   
        }
    ?>

Answer 2

这是给你的代码：

$hue = json_decode(file_get_contents('https://api.twitch.tv/kraken/channels/starladder1'));
echo "Name :" .$hue->display_name;

你只是做错了 url 来获取

Answer 3

它不起作用的原因是因为您尝试直接访问“display_name”而不分析对象的结构。

尝试这个：

print_r($hue->streams[0]->channel->display_name);

您会看到流以“[”开头，这意味着它的元素像数组一样被访问

您的对象确实看起来像这样，这有助于您更好地理解结构：
