首先定义一个数组用于存储签名所需的各个参数 , 并用 ksort 方法对其进行键名的升序排序 $array [ 'access_token' ]= $accesstoken ; $array [ 'app_id' ]= $appid ; $array [ 'timestamp' ]=date( 'Y-m-jG:i:s' ); ksort( $array ); 将数组传入 buildPlainT

$array['access_token']=$accesstoken;
$array['app_id']=$appid;
$array['timestamp']=date('Y-m-jG:i:s');
ksort($array);
将数组传入buildPlainText方法生成明文
$plaintext= buildPlainText($array);
将明文加密成为接口中所需的入参sign,$appsecret为应用密钥
$cipherText= base64_encode(hash_hmac("sha1",$plaintext,$appsecret,$raw_output=True));
$cipherText= urlencode($cipherText);
