At step 5, i get a res is {“Message”:“An error has occurred.”} after i send a post to https://login.eveonline.com/v2/oauth/token

  1. I want to know how to solve it ?

im sure that headers , Authorization , and code is correct;

  1. Why the demo in the official document used ’ json ’ , but document said use Content-Type: application/x-www-form-urlencoded ?

You’re going to need to provide more information/code in order to figure this out. That message isn’t enough to go off of.

Where do you see it using JSON? Got a link?

	fmt.Println(o)
	req, err := http.NewRequest("POST", "https://login.eveonline.com/v2/oauth/token", strings.NewReader(o))
	req.Header.Add("Authorization", "Basic YjgzMTg0ZGUzNWQ4NGYxODk4ZmZlZjM0MDczNjUwZjE6Q2ZLQWY0VnQ5MUt4eVFIM2c5a21sZkx3MWxRQ3FQVEZaRU9peVl2VA==")
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
	if err != nil {
		panic(err)
	}
	defer req.Body.Close()
	client := &http.Client{Timeout: 15 * time.Second}
	resp, error := client.Do(req)
	if error != nil {
		panic(error)
	}
	defer resp.Body.Close()
	result, _ := ioutil.ReadAll(resp.Body)
	content = string(result)
	return
}

Are you getting the code from the right endpoint? https://login.eveonline.com/v2/oauth/authorize/? I did some testing and apparently this is the error that’s returned when the code is invalid. So either you’re getting the code from the non v2 endpoint, or something with the Go code isn’t entirely correct. If you are using the v2 endpoint, try making the request via Postman or curl to see if that works; if so then you know something is up with the code.

Also, I’d be sure to cycle your OAuth app secret key given it’s just been exposed publicly.

That’s not JSON. That’s a Python dict.

yes, the code not from the non v2 endpoint,thank you very much!
