Sending JSON response from NodeJS/Express
提问by Dreemlife
sorry for the n00b question I have been kinda stuck so I was hoping you guys could put me in the right direction.
抱歉 n00b 问题我有点卡住了所以我希望你们能把我放在正确的方向上。
I am making an app that is retrieving data by NODEJS from a REST API. (This is a success and works).
我正在制作一个通过 NODEJS 从 REST API 检索数据的应用程序。（这是成功且有效的）。
I then have a listen URL (my own API) in express that I invoke by going to the browser http://localhost/apior by using POSTMAN. So far so good, I see in the console (NODE Console) that my request gets handled perfectly as I see the JSON response, however, I would also like to see the JSON response in the browser or POSTMAN as JSON Response, not just the console I know I am missing something in my (simple) code but I am just starting out.... Please help me out here is my code.
然后我在 express 中有一个侦听 URL（我自己的 API），我通过转到浏览器http://localhost/api或使用 POSTMAN 来调用它。到目前为止一切顺利，我在控制台（节点控制台）中看到，当我看到 JSON 响应时，我的请求得到了完美的处理，但是，我还希望在浏览器或 POSTMAN 中将 JSON 响应视为 JSON 响应，而不仅仅是控制台 我知道我的（简单）代码中遗漏了一些东西，但我才刚刚开始......请帮助我，这是我的代码。
var express = require("express");
var app = express();
const request = require('request');
const options = {
url: 'https://jsonplaceholder.typicode.com/posts',
method: 'GET',
headers: {
'Accept': 'application/json',
'Accept-Charset': 'utf-8',
}
};
app.get("/api", function(req, res) {
request(options, function(err, res, body) {
var json = JSON.parse(body);
console.log(json);
});
res.send(request.json)
});
app.listen(3000, function() {
console.log("My API is running...");
});
module.exports = app;
Much appreciated!
非常感激！

Much thanks to ProgXx, turned out I used the same res and response names. Here is the final code. Much thanks ProgXx
非常感谢 ProgXx，原来我使用了相同的 res 和响应名称。这是最终的代码。非常感谢 ProgXx
var express = require("express");
var app = express();
const request = require('request');
const options = {
url: 'https://jsonplaceholder.typicode.com/posts',
method: 'GET',
headers: {
'Accept': 'application/json',
'Accept-Charset': 'utf-8',
'User-Agent': 'my-reddit-client'
}
};
app.get("/api", function(req, res) {
request(options, function(err, output, body) {
var json = JSON.parse(body);
console.log(json); // Logging the output within the request function
res.json(json) //then returning the response.. The request.json is empty over here
}); //closing the request function
});
app.listen(3000, function() {
console.log("My API is running...");
});
module.exports = app;

To send json response from express server to the frontend use res.json(request.json)instead of res.send(request.json).
要将 json 响应从 express 服务器发送到前端，请使用res.json(request.json)而不是res.send(request.json).
app.get("/api", function(req, res) {
request(options, function(err, res, body) {
var json = JSON.parse(body);
console.log(json); // Logging the output within the request function
}); //closing the request function
res.send(request.json) //then returning the response.. The request.json is empty over here
});
Try doing this
尝试这样做
app.get("/api", function(req, res) {
request(options, function(err, response, body) {
var json = JSON.parse(body);
console.log(json); // Logging the output within the request function
res.json(request.json) //then returning the response.. The request.json is empty over here
}); //closing the request function
});
