My reference: https://github.com/tinode/chat/blob/master/pbx/model.proto
I have the following response from a grpc call:
&{id:"4" topic:"fnd" sub:<updated_at:1588240740070 acs:<> public:"{"fn":"
Yogeswari","pn":"Yoges"}" private:"["mhub:e995b6be-b528-4d1b-9e52-
cdcca7ebf4d6"]" user_id:"usr4M22x6F-Fq4" > }
It is returned by res.GetMessage.
go func() {
// function to receive a bunch of messages
for {
res, err := stream.Recv()
if err == io.EOF {
break
}
if err != nil {
log.Fatalf("Error while receiving: %v", err)
break
}
fmt.Printf("Received: %v\n", res.GetMessage())
}
close(waitc)
}()
I need to extract the user_id from the response and I'm able to do it the
following way:
msg := fmt.Sprintf("%v", res.GetMessage())
s := strings.Index(msg, "user_id:")
if s != -1 {
s += len("user_id:")
e := strings.Index(msg, " > }")
if e != -1 {
fmt.Printf("pos: %s", msg[s:e])
}
}
What is the right way to extract the response? How can I assign the result
to a struct (or something else) for easy access in the rest of the code?
Apology if I'm using some incorrect terms in the question. I'm new to both
golang and grpc.
Thank you for reading.
