The basic development of the block chain starter Tutorial to inquire about currency withdrawal by interface BCH

The code is as follows
　　
　　
Package Main
　　
Import (
"Encoding/json"
"FMT"
　　
"Github.com/buger/jsonparser"
"Github.com/levigross/grequests"
)
　　
HttpGet.

HttpResponse, err: = Grequests. Get (URL, requestoptions)

if Httpresponse.statuscode = = 200 {
Response = Httpresponse.bytes ()
}
}
Return
}
