Error in calling the IO function

I call the IO function as it says in the API documentation to call the OKEX contract information.

var ret = exchange.IO("api", “POST”, “/api/v1/future_position.do”, “symbol=eth_usd&contract_type=this_week”) Log(ret)

The error message is as follows:

2018-10-19 11:15:07 This is my first post. The information false 2018-10-19 11:15:07 This is my first post. Futures_OKCoin is a cryptocurrency. Mistakes This is the future.

Where did I get the problem? Apkey also uses v1.
