Question

我只编写原始API NodeJS。
我的问题是服务器返回[对象对象]而不是JSON
这是我的代码：

const http = require('http');

http.createServer((request, response) => {
  const { headers, method, url } = request;
  let body = [];
  request.on('error', (err) => {
    console.error(err);
  }).on('data', (chunk) => {
    body.push(chunk);
  }).on('end', () => {
    body = Buffer.concat(body).toString();
    // BEGINNING OF NEW STUFF

    response.on('error', (err) => {
      console.error(err);
    });

    response.statusCode = 200;
    response.setHeader('Access-Control-Allow-Origin', '*');
    response.setHeader('Content-Type', 'application/json');
    // Note: the 2 lines above could be replaced with this next one:
    // response.writeHead(200, {'Content-Type': 'application/json'})

    const responseBody = { headers, method, url, body };

    response.write(body);
    response.end();
  });
}).listen(2018);

无论如何感谢支持我:)。

问题出在response.write。它期望一个字符串，而不是JS对象，所以你需要对响应进行字符串化：

const http = require('http');

http.createServer((request, response) => {
  const { headers, method, url } = request;
  let body = [];
  request.on('error', (err) => {
    console.error(err);
  }).on('data', (chunk) => {
    body.push(chunk);
  }).on('end', () => {
    body = Buffer.concat(body).toString();
    // BEGINNING OF NEW STUFF

    response.on('error', (err) => {
      console.error(err);
    });

    response.statusCode = 200;
    response.setHeader('Access-Control-Allow-Origin', '*');
    response.setHeader('Content-Type', 'application/json');
    // Note: the 2 lines above could be replaced with this next one:
    // response.writeHead(200, {'Content-Type': 'application/json'})

    const responseBody = { headers, method, url, body };

    response.write(JSON.stringify(responseBody));
    response.end();
  });
}).listen(2018);

在没有框架的情况下创建Raw API NodeJS
