В моем приложении Node я пытаюсь просмотреть объект request.body, чтобы проверить наличие элементов, которые входят в него, но console.log(req.body) радуется, что он пуст. Вот мои файлы.
app.js файл ниже
var express = require("express");
var app = express();
var mongoose = require("mongoose");
var nationalPark = require("./models/NationalParks");
//config
mongoose.connect('mongodb://localhost/National_Parks', {useNewUrlParser: true, useUnifiedTopology: true}).catch(function(reason){
console.log('Unable to connect to the mongodb instance. Error: ', reason);
});
app.set('view engine', 'ejs');
var bod = require("body-parser");
app.use(bod.urlencoded({extended:true}));
app.use(bod.json());
app.use(express.static(__dirname + '/resources'));
//Routes
app.get("/",function(req,res){
nationalPark.find({},function(err,nationalParks){
if(err){
console.log(err);
}else{
res.render("home",{nationalParks:nationalParks});
}
})
});
app.get("/home",function(req,res){
nationalPark.find({},function(err,nationalParks){
if(err){
console.log(err);
}else{
console.log(nationalParks);
res.render("home",{nationalParks:nationalParks});
}
})
});
app.get("/login",function(req,res){
res.render("login");
});
app.get("/signup",function(req,res){
res.render("signup");
});
app.get("/logout",function(req,res){
res.render("home");
});
app.get("/NationalPark",function(req,res){
console.log(park.park)
res.render("NationalPark",{park:park.park});
});
app.post("/NationalPark",function(req,res){
console.log(req.body);
res.render("NationalPark");
});
app.get("/post",function(req,res){
res.render("post");
});
app.get("/post-display",function(req,res){
res.render("post-display");
});
app.get("/profile",function(req,res){
res.render("profile");
});
//listening port
app.listen(3000,function(){
console.log("Server started");
});
Вот мой home.ejs файл

в следующем методе публикации в app.js
app.post("/NationalPark",function(req,res){
console.log(req.body);

});
console.log(req.body) просто печатает {}
Почему это происходит, я что-то упустил? Буду глубоко признателен за вашу помощь. Заранее спасибо.
