PHP API代理示例

流程：请求 API → 解析 JSON → 处理错误 → 使用返回代理访问目标站。

file_get_contents + stream 上游代理

2    $apiUrl = 'http://ip.16yun.cn:817/myip/pl/<ORDER_ID>/?s=<ORDER_SIGN>&u=<USER>&format=json';

4    $json = file_get_contents($apiUrl);
5    if ($json === false) {
6        die('API 请求失败');
7    }
8    $arr = json_decode($json, true);
9    if (!is_array($arr) || count($arr) === 0) {
10        die('API 返回为空');
11    }
12    $ip = $arr[0]['ip'];
13    $port = $arr[0]['port'];

15    $proxy = "tcp://{$ip}:{$port}";
