我正在嘗試使用 golang 構建一個 API。首先，當我訪問http://localhost:8085/search時，我只是嘗試發送一些 json 數據，但我在瀏覽器中看到的只是null.package mainimport (? ? "log"? ? "net/http"? ? "encoding/json"? ? "github.com/gorilla/mux")type Place struct {? Location string `json:"123 Houston st"`? Name string `json:"Ricks Barber Shop"`? Body string `json:"this is the best barber shop in the world"`}var place []Placefunc search(write http.ResponseWriter, req *http.Request) {? ? write.Header().Set("Content-Type", "application/json")? ? json.NewEncoder(write).Encode(place)}func main() {? ? router := mux.NewRouter().StrictSlash(true)? ? router.HandleFunc("/search", search).Methods("GET")? ? log.Fatal(http.ListenAndServe(":8085", router))}
