如何将定界字符串解析为子字符串切片？

Question

Given a URL like the following:

http://127.0.0.1:3001/find?fields=hostname,App,Node_type,invalid

I extract fields into a slice like this:

filters := r.URL.Query().Get("fields")
fmt.Println(filters)

Result:

hostname,App,Node_type,invalid

It is received as a string, but I'd prefer to separate the substrings into a sequence.

Answer 1

I think your URL should be

http://127.0.0.1:3001/find?fields=hostname&fields=App&fields=Node_type&fields=invalid

or if you don't like that, you can parse

filterSlice:=strings.Split("filters", ",")
