hi,
This is what i have done so far but still need some help as to how to
return ""v.APIVersionInURI" in the loop function (FindAlluris()) .
Am trying to write a function which will return all the
field ""v.APIVersionInURI" in the mongo db and then
use this function in my API handler function. I have tried this
// The strut look like this
type NfInstance struct {
ID bson.ObjectId `bson:"_id" json:"id"`
NfServices []Service `json:"nfServices" bson:"nfServices"`
......
}
type Service struct {
Versions []Version `json:"versions" bson:"versions"`
......
}
type Version struct {
APIVersionInURI string `json:"apiVersionInUri" bson:"apiVersionInUri"`
...
}
// Establish a connection to database
func (m *NfInstanceDataAccess) Connect() {
session, err := mgo.Dial(m.Server)
if err != nil {
log.Fatal(err)
}
db = session.DB(m.Database)
}
// Find list of nfinstances URIs
func (m *NfInstanceDataAccess) FindAlluris() (NfInstance, error) {
nfInstance := NfInstance{}
itr := db.C(COLLECTION).Find(bson.M{}).Iter()
for itr.Next(&nfInstance) {
for _, svc := range nfInstance.NfServices {
for _, v := range svc.Versions {
fmt.Println(v.APIVersionInURI)
}
}
}
if err := itr.Close(); err != nil {
fmt.Println(err)
}
}
but dont know where to return all "v.APIVersionInURI" strings.
The handler function look like this
// Get all database URIs
func NfInstanceUrlsGet(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json; charset=UTF-8")
uris, err := da.FindAlluris()
if err != nil {
respondWithError(w, http.StatusInternalServerError, err.Error())
return
}
respondWithJson(w, http.StatusOK, uris)
}
Thanks in advance
