What is the difference between HttpQuery and IO?

Author: The bride too., Created: 2018-05-11 15:21:58, Updated:

Below are two lines of code that show the market for the various currencies that receive the yuan:

var all_tciker_bian = HttpQuery(“https://www.binance.com/api/v1/ticker/24hr”)

var all_tciker_bian = exchanges[0].IO(“api”, “GET”, “/v1/ticker/24hr”)

However, with HttpQuery there is no problem, but with IO it always returns an error, as follows: Futures_OP 4: 404: 404 Not Found white>

404 Not Found
