golang大猩猩/ mux和休息GET问题

Question

My Delete Handler: (I am using "github.com/gorilla/mux")

func DeletePerson(w http.ResponseWriter, r *http.Request) {
params := mux.Vars(r)
item := params["id"]
fmt.Println("Item = ", item)
...

returns Item = "2" when called by the following curl command:

curl -X DELETE http://localhost:8000/address/2

However, my TEST Code:

func TestDeletePerson(t *testing.T) {
person := &Person{
    UniqID:    "2",
    FirstName: "",
    LastName:  "",
    EmailAddr: "",
    PhoneNumb: "",
}

jsonPerson, _ := json.Marshal(person)
request, _ := http.NewRequest("DELETE", "/address/2", bytes.NewBuffer(jsonPerson))

response := httptest.NewRecorder()
DeletePerson(response, request)

Results in DeletePerson returning "" and printing "params" directly returns

map[]

Big Question - WHAT IN HELL AM I MISSING???

Is there another header parameter I have set?

Answer 1

Because you didn't initalize router. Try this

func TestDeletePerson(t *testing.T) {
    r := mux.NewRouter()
    r.HandleFunc("/adress/{id}", DeletePerson).Methods("DELETE")
    request, _ := http.NewRequest("DELETE", "/adress/2", nil)

    response := httptest.NewRecorder()
    r.ServeHTTP(response, request)
}

Also I think you dont need to send Person object for deletion
