I have a simple HTTP server running. I am trying to send a list of values to this server using curl.
curl -X POST -d "["student1", "student2"]" http://localhost:8080/
How can I read the body as a string slice? I tried b, _ := io.ReadAll(r.Body) but it reads the array as one item rather than an array.
You can use json decoder to decode the values in slice of string
var arr []string
err := json.NewDecoder(req.Body).Decode(&arr)
if err != nil {
fmt.Fprintf(w,fmt.Sprintf("Error:%+v",err))
return
}
fmt.Println(arr)
Try with this :P
curl -X POST -d '["student1", "student2"]' http://localhost:8080
The quotes were breaking the payload parsing.
This also works:
curl -X POST -d "[\"student1\", \"student2\"]" http://localhost:8080
Your go server is probably reciving a payload that looks like this [student1, student2] instead of looking like this ["student1", "student2"]
After you have your well formed json string array being sent, you can parse it like this:
var body []string
e := json.NewDecoder(r.Body).Decode(&body)
fmt.Println(e, body[0]) // nil "student1"
