CodePudding user response：

As the documention say : all the query string has to be signed. Becarefull with the need of urlencode. This PHP example give the same result as the documentation :

<?php
$raw = "symbol=LTC/BTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559";
$signkey = "NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j";
$signature = hash_hmac('sha256', $raw, $signkey, false);
echo $signature; //ebec6528b2beb508b2417fa33453a4ad28c1aae8097bb243caa60d0524036f50
