“类型错误：response.write 不是一个函数”错误
我正在尝试学习一些 Node.js，这是我的第一个教程项目。 虽然我改变了一些小东西，但我主要遵循这个教程。 https://www.youtube.com/watch?v=PFJHQ2g6s0k&ab_channel= itsTechMode
我的 JS 代码如下。
const http = require('http');
const url = 'https://api.openweathermap.org/data/2.5/weather?q=Athens,GR&appid=a7003b6a9783fdc3503466334cbd605b&units=metric';
let data;
var server = http.createServer(function(request,response){
var request = require('request');
response.writeHead(200, {'Content-Type': 'text/plain'});
response.write("Hello write");
response.end('Hello World\n');
request({ url: url }, (error, response, body) => {
if (error) {
console.log(error)
}
let data = JSON.parse(body);
response.write("Trying to print this.");
response.end();
// response.write("<html><body><div id='container'>");
// response.write("<h1>" +"City Name - :"+ data['name']+"<br>"+"</h1>");
// response.write("<h2>"+ "Temperature - :" + data.main['temp'] + "<br>"+"</h2>");
// response.write("<h2>"+"Sunset Time - :"+ new Date(data.sys["sunset"]+1000)+ "</h2>");
// response.write("</div></body></html>");
console.log(response.body)
response.end();
});
}).listen(8000, "127.0.0.1");我收到“TypeError：response.write 不是函数” Stackoverflow 不允许我添加图片。所以这里是错误屏幕截图的链接。 有人可以帮我吗？另外，如果这篇文章的格式看起来很奇怪，我很抱歉。我尽力让它看起来最好，但我是这里的新手。
I'm trying to learn some Node.js and this is my first tutorial project.
Although I changed some minor things, I mainly followed this tutorial.
https://www.youtube.com/watch?v=PFJHQ2g6s0k&ab_channel=ItsTechMode
My JS code is below.
const http = require('http');
const url = 'https://api.openweathermap.org/data/2.5/weather?q=Athens,GR&appid=a7003b6a9783fdc3503466334cbd605b&units=metric';
let data;
var server = http.createServer(function(request,response){
var request = require('request');
response.writeHead(200, {'Content-Type': 'text/plain'});
response.write("Hello write");
response.end('Hello World\n');
request({ url: url }, (error, response, body) => {
if (error) {
console.log(error)
}
let data = JSON.parse(body);
response.write("Trying to print this.");
response.end();
// response.write("<html><body><div id='container'>");
// response.write("<h1>" +"City Name - :"+ data['name']+"<br>"+"</h1>");
// response.write("<h2>"+ "Temperature - :" + data.main['temp'] + "<br>"+"</h2>");
// response.write("<h2>"+"Sunset Time - :"+ new Date(data.sys["sunset"]+1000)+ "</h2>");
// response.write("</div></body></html>");
console.log(response.body)
response.end();
});
}).listen(8000, "127.0.0.1");I get the "TypeError: response.write is not a function"
Stackoverflow does not allow me to add a pic. so here is a link to the error screenshot.
Can someone help me about it? Also, sorry if the this post's format looks weird. I tried to make it look as best as I could but I'm a newbie around here.

此行中的参数
response：var server = http.createServer(function(request,response){...}是您需要用来执行“ response.write”，但是在这里：
request({ url: url }, (error, response, body) => {您还有一些其他参数，您将其命名为“response”。这使得原始“响应”变量将
request(...)调用中的参数名称更改为“resp”或其他名称，并确保在回调中使用“resp.body”。The parameter
responsein this line:var server = http.createServer(function(request,response){...}Is what you need to use to do stuff like "response.write", however here:
request({ url: url }, (error, response, body) => {You have some other parameter which you are naming "response". That makes the original "response" variable inaccessible.
Change the parameter name in the
request(...)call to "resp" or something. And be sure to use "resp.body" within the callback.
