How to make the Binance money?

Example 1: As a query string

queryString: symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559

HMAC SHA256 signature:

[linux]$ echo -n “symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559” | openssl dgst -sha256 -hmac “NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j” (stdin)= c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71

He needs to add a timestamp parameter and then sign the entire querystring. I try. var querystr = asset=abc&amount=100 & address=abc×tamp=abc; var sig = HMAC ((sha256,hex, querystr, secretkey);// The second argument has been tried exchange.IO ((api button, POST button, /wapi/v3/withdraw.html button, querystr+&signature=+sig); or exchange.IO ((api button, POST button, /wapi/v3/withdraw.html button, querystr); Get it {msg:{\code\:-1105,\msg\:\Parameter payload was was empty.\}

exchange.IO ((api, POST, /wapi/v3/withdraw.html?+querystr+&signature=+sig,);//ru I will. {msg:{\code\:-1100,\msg\:\ Illegal characters found in parameter signature; legal range is ^[A-Fa-f0-9]{64}$.\},success:false}

If not signed {msg:{\code\:-1022,\msg\:\ Signature for this request is not valid.\}
