最佳答案
问题: 目前我正在 func Index
中打印我的回复
就像这个 fmt.Fprintf(w, string(response))
然而,如何在请求中正确地发送 JSON,以便它可能被视图使用?
package main
import (
"fmt"
"github.com/julienschmidt/httprouter"
"net/http"
"log"
"encoding/json"
)
type Payload struct {
Stuff Data
}
type Data struct {
Fruit Fruits
Veggies Vegetables
}
type Fruits map[string]int
type Vegetables map[string]int
func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
response, err := getJsonResponse();
if err != nil {
panic(err)
}
fmt.Fprintf(w, string(response))
}
func main() {
router := httprouter.New()
router.GET("/", Index)
log.Fatal(http.ListenAndServe(":8080", router))
}
func getJsonResponse()([]byte, error) {
fruits := make(map[string]int)
fruits["Apples"] = 25
fruits["Oranges"] = 10
vegetables := make(map[string]int)
vegetables["Carrats"] = 10
vegetables["Beets"] = 0
d := Data{fruits, vegetables}
p := Payload{d}
return json.MarshalIndent(p, "", " ")
}
