使用ajax获取萤石云的accessToken时，appKey和secret直接暴露在前端HTML代码中，且success返回的accessToken在异步的情况下，无法作为全局变量使用。为此，在后端中获取accessToken，是非常必要的。
$curl函数封装;
//封装POST函数; function posturl($url, $data) { //把数组形式的参数转为‘appkey=....&secret=...'这种形式; $data = http_build_query($data); $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_BINARYTRANSFER, true); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); //输出结果; return json_decode($output, true); }
参数设置
//调用URL; $url = "https://open.ys7.com/api/lapp/token/get"; //请求参数; $data = ["appKey" => "bcb59***", "appSecret" => "a749326a19***"];
获取accessToken
//01.获取accessToken $content = posturl($url, $data); $accessToken = $content["data"]["accessToken"];
使用accessToken
//02.获取设备列表; //调用URL; $url1 = "https://open.ys7.com/api/lapp/device/list"; //请求参数; $data1 = ["accessToken" => $accessToken]; $content1 = posturl($url1, $data1); echo "<pre>"; var_dump($content1);
Done！
