JSON in API call is not decoding correctly, I am getting a blank struct

Question

My JSON looks like this:

{ "website": { "id": 8, "account_id": 9, "name": "max", "website_url": "", "subscription_status": "trial", "created_at": "2016-01-24T01:43:41.693Z", "updated_at": "2016-02-21T01:17:53.129Z", } }

My Website struct looks like this:

type Website struct { Id int64 `json:"id"` AccountId int64 `json:"account_id"` Name string `json:"name"` WebsiteUrl string `json:"website_url"` SubscriptionStatus string `json:"subscription_status"` CreatedAt time.Time `json:"created_at"` UpdatedAt time.Time `json:"updated_at"` }

I then have a Company struct like:

type Company struct { Website Website api *API }

So in my API client code I have this:

res, status, err := api.request(endpoint, "GET", nil, nil) if err != nil { return nil, err } if status != 200 { return nil, fmt.Errorf("Status returned: %d", status) } r := map[string]Company{} err = json.NewDecoder(res).Decode(&r) fmt.Printf("things are: %v\n\n", r)

The output I am getting is this:

things are: map[website:{{0 0 0001-01-01 00:00:00 +0000 UTC 0001-01-01 00:00:00 +0000 UTC} <nil>}]

How can I debug this, I am not sure why it is not setting the Website struct with correct values.

Update

I added this, I don't see any output:

if err != nil { fmt.Printf("error is not nillllllll!!!:") fmt.Println(err) return nil, err }

@hobbs I updated my question with the error code, I don't see any output. — Blankman

Its because you have too many levels of nesting with the map > Company > Website. The map effectively builds another layer on top of it so its expecting three levels of JavaScript objects nested. In actuality, the JSON you provided only has two with Company > Website.

So there are a couple of ways to get it to work; choose the one that works best for you.

You can do:

r := map[string]Website{} json.NewDecoder(res).Decode(&r)

Or you can do:

r := Company{} json.NewDecoder(res).Decode(&r)

thanks! btw, any links to a production example of a API client that I should look at?
No problem! I tend to just use the http.Client and add another layer of abstraction if I need something more domain specific. Not sure if that helps.
