After getting a list of media items and a list of albums from the Google Photo API (using Go and the Google Photo REST API), adding items to an album returns an error.
(Note: using the web interface to add the items to the album works fine).
Code to add the media item to the album:
func (a Album) AddItems(items ...MediaItem) error {
rel := &url.URL{Path: fmt.Sprintf("/v1/albums/%s:batchAddMediaItems", a.ID)}
u := a.service.baseURL.ResolveReference(rel)
for len(items) > 0 {
ids := []string{}
for i := 0; i < 50 && i < len(items); i++ {
ids = append(ids, items[i].ID)
}
items = items[len(ids):]
toAdd := map[string]interface{}{
"mediaItemIds": ids,
}
bodyData, err := json.Marshal(toAdd)
if err != nil {
return err
}
req, err := http.NewRequest("POST", u.String(), bytes.NewBuffer(bodyData))
if err != nil {
return err
}
resp, err := a.service.client.Do(req)
if err != nil {
return err
}
defer resp.Body.Close()
respErr := struct {
Error ServerError `json:"error"`
}{}
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
return err
}
err = json.Unmarshal(body, &respErr)
if err != nil {
return err
}
err = respErr.Error.Error()
if err != nil {
return err
}
}
return nil
}
The server returns the following error:
error 400: Request contains an invalid media item id. (INVALID_ARGUMENT).
The media item ID is copied from the ID field of the JSON representation of a media item returned from a search request. The other fields of the media item seem to be valid (e.g. the ProductURL).
What is wrong in this batchAddMediaItems request? or how to get a valid media item ID suitable for batchAddMediaItems ?
Thank you.
