阿里云取出所有直播间的接口

上午一直在调试安卓同事的一个直播间接口

测试了好几种方法，最后快实现的时候，循环调用出现了问题

最后在 csdn上找到了解决方法

直接上代码吧，挺坑的，阿里的接口，也没注释，都不知道怎么做。

<?php
	header("Content-type: text/html; charset=utf-8"); 
	//phpinfo();
	function curl_http_request($url,$data = null)

		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
		//如果$data不为空,则为POST请求
		if (!empty($data)){
			curl_setopt($ch, CURLOPT_POST, 1);
			curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
		}
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
		$output = curl_exec($ch);
		$error = curl_error($ch);
		curl_close($ch);
		if ($error){
			throw new Exception('请求发生错误：' . $error);
		}
		//$resultArr = json_decode($output, true);//将json转为数组格式数据

他把所有的功能都实现了， 直接使用就可以了！
