I ran into a little issue as I tried to POST to a Go backend using Axios but I could not get the parameters I was sending.
I was doing this:
func handleReq(w http.ResponseWriter, req *http.Request) {
err := req.ParseForm()
if err != nil {
panic(err)
}
v := req.Form
owner := req.Form.Get("owner")
name := req.Form.Get("name")
//...
}
but the two parameters I was looking for were not available. Why?
Turns out that I was assuming Axios sent the parameters using Content-Type:application/x-www-form-urlencoded but by default it’s using Content-Type:application/json.
Note: you can configure it to use
application/x-www-form-urlencoded, check https://github.com/axios/axios#using-applicationx-www-form-urlencoded-format
This means that to access the parameters I need to decode them using json.Decoder.
Here is some sample code that does the trick:
type myData struct {
Owner string
Name string
}
func handleAddNewRepo(w http.ResponseWriter, req *http.Request) {
decoder := json.NewDecoder(req.Body)
var data myData
err := decoder.Decode(&data)
if err != nil {
panic(err)
}
owner := data.Owner
name := data.Name
//...
}
