我在URL上将实体“ id”作为字符串传递，例如：
..../foo/234565
我想在以下查询中使用ID：
//...i hace some code that gets stringId from the URL, and I verified that it works stringId = .... theKey, err := datastore.DecodeKey(stringId) q := datastore.NewQuery("Foo").Filter("__key__ =", theKey)
我得到的错误：
proto: can't skip unknown wire type 7 for datastore.Reference
有没有一种简单的方法可以将stringId转换为“ Key”？
c := appengine.NewContext(r) //Retrieve the entity ID from the submitted form. Convert to an int64 entity_id := r.FormValue("entity_id") entity_id_int, err := strconv.ParseInt(entity_id, 10, 64) if err != nil { fmt.Fprint(w, "Unable to parse key") return; } //We manufacture a datastore key based on the Kind and the //entity ID (passed to us via the HTTP request parameter. key := datastore.NewKey(c, kind, "", entity_id_int, nil) //Load the Entity this key represents. //We have to state the variable first, then conduct the Get operation //so the datastore understands the struct representing the entity. var entity CustomStruct datastore.Get(c, key, &entity)
