带有 POST 请求的 Express JS 路由在 Postman 中返回 404 无法 GET 错误

Question

我正在使用 express 和 body-parser 在 Nodejs 中创建 API。 我能够使用邮递员成功发出 GET 请求，但是在使用 POST 请求时，它总是抛出错误404 not found 无法 GET /

请检查下面的代码

server.js 文件

require('dotenv').config();
const express = require("express");
const http = require("http");

var addRequestId = require('express-request-id')();
const requestIp = require('request-ip');
const cron = require("node-cron");
const cluster = require('cluster');
const os = require('os');
const v1 = require('./routes/v1');
const jobs = require('./routes/jobs/sync_job');
const bodyParser = require("body-parser");

// Check if current process is master.
if (cluster.isMaster) {

  // Get total CPU cores.
  const cpuCount = os.cpus().length;

  // Spawn a worker for every core.
  for (let j = 0; j < cpuCount; j++) {
    cluster.fork();
  }



  var port = parseInt(3000);
  var app = express();

  var server = http.createServer(app);
  app.use(addRequestId);
  app.use(requestIp.mw())
  app.use(bodyParser.json({limit: '50mb'}));
  app.use(bodyParser.urlencoded({limit: '50mb', extended: false}));
  server.listen(port, () => { })
  console.log("SERVER UP AND RUNNING");

  app.use('/v1/jp', require('./routes/report_center'));



}


cluster.on('exit', function (worker) {
  console.log(`Worker ${worker.id} died'`);
  console.log(`Staring a new one...`);
  cluster.fork();
});

屏幕截图中的以下错误

经过两天的努力，找到了被称为邮递员的罪魁祸首，他用不同的发件人姓名递送我的信件，我的意思是它只是将所有方法路由到 GET 类型。

默认情况下，屏幕截图中的以下设置已关闭。

我只是希望它可以帮助那些不应该感到沮丧并节省时间而不是像我这样的人
