向Golang API发出发送JSON和stringy-fied JSON的请求

在制作 POST 请求Golang API,如果我发送stringy-fied JSON 数据返回成功,但当我发送 JSON 返回错误的数据 status 403 .

请帮助我了解这种行为以及如何发送 JSON 数据使用 发布 请求方法。

文件:main。去

package main

import (
    "devmgmtv2/auth"
    "github.com/gorilla/handlers"
    "github.com/gorilla/mux"
    "log"
    "net/http"
)

func main() {
    router := mux.NewRouter()
    auth.AuthInit(router)
    ssid.SsidInit(router)
    headersOk := handlers.AllowedHeaders([]string{"X-Requested-With"})
    originsOk := handlers.AllowedOrigins([]string{"*"})
    methodsOk := handlers.AllowedMethods([]string{"GET", "HEAD", "POST", "PUT", "OPTIONS"})
    router.HandleFunc("/auth/login", Login).Methods("POST", "OPTIONS")
    log.Fatal(http.ListenAndServe(":8000", handlers.CORS(headersOk, originsOk, methodsOk)(router)))
}

func Login(w http.ResponseWriter, r *http.Request) {
    //Create User Struct
    var user User
    json.NewDecoder(r.Body).Decode(&user)
    userPassword := getUserPassword(user.User)
    // call get value for that user
    // check for equality if true, return the structure
    // if false return error
    if user.Password == userPassword {
        w.Header().Set("Content-Type", "text/plain")
        w.Write([]byte("success"))
    } else {
        http.Error(w, "Forbidden", http.StatusForbidden)
    }
}
