使用 Node.js 从 API 填充数据

在使用 Node.js 从 API 填充用户数据时，我遇到了错误：“write after end”。我使用 async 函数来获取数据并在使用接收到的数据将其写入节点服务器的文档之前使用 await。

谢谢你的帮助！

const http = require('http');
const https = require('https');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    homeVerleitung(req, res);
    userVerleitung(req, res);
    res.end('Footer\n');
});

server.listen(port, hostname, () => {
    console.log(`Server running at http://${hostname}:${port}/`);
});

function homeVerleitung(request, response) {
    if (request.url === '/') {
        response.setHeader('Content-Type', 'text/plain');
        response.write('Header\n');
        response.write('Home\n');
    }
}

function userVerleitung(request, response) {
    if (request.url.length > 1) {
        response.setHeader('Content-Type', 'text/plain');
        const usedUrl = request.url.replace('/', '');
        response.write('Header\n');
        response.write(`${usedUrl}\n`);
        const asyncFunk = async (request, response) => {
            const userData = await getProfile(usedUrl);
            await response.write('Name of User is: ' + userData.name);
            await response.end('End');
        };
        asyncFunk(request, response);
    }
}

function getProfile(url) {
    return new Promise((resolve, reject) => {
        https
            .get(`https://teamtreehouse.com/${url}.json`, (res) => {
                let body = '';

                res.on('data', (d) => {
                    body += d.toString();
                });
                res.on('end', (d) => {
                    const jsonBody = JSON.parse(body);
                    resolve(jsonBody);
                });
            })
            .on('error', (e) => {
                console.error(e);
            });
    });
}
