快递路由器路由在Postman上获取状态404

Question

我试图通过Postman测试在express中完成的路由，但我一直处于404状态，尽管我有另一条路由可以工作。

我不会把代码发布到有效的路线上，因为这里写了很多代码，似乎没有必要。

App.js

var createError = require("http-errors");
var express = require("express");
var path = require("path");
var cookieParser = require("cookie-parser");
var logger = require("morgan");
var cors = require("cors");
require("dotenv").config();
var bodyparser = require("body-parser")
var indexRouter = require("./routes/index");
var usersRouter = require("./routes/users");
var commentsRouter = require("./routes/comments")
var authRouter = require("./routes/auth")
var app = express();
var corsOption = {
origin: true,
methods: 'GET,HEAD,PUT,PATCH,POST,DELETE',
credentials: true,
exposedHeaders: ['x-auth-token']
};
// view engine setup
app.use(cors(corsOption));
app.use(logger("dev"));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, "public")));
app.use(bodyparser.json());
app.use(bodyparser.urlencoded({ extended: false }));
app.use(function (req, res, next) {
if (req.originalUrl && req.originalUrl.split("/").pop() === "favicon.ico") {
return res.sendStatus(204);
}
return next();
});
app.use("/", indexRouter);
app.use("/users", usersRouter);
app.use("/comments", commentsRouter)
app.use("/auth", authRouter)
// catch 404 and forward to error handler
app.use(function (req, res, next) {
next(createError(404));
});
// error handler
app.use(function (err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get("env") === "development" ? err : {};
// render the error page
res.status(err.status || 500);
res.render("error");
});
module.exports = app;

评论路线

var express = require("express");
var router = express.Router();

//Get comment
router.get("/", function (req, res, next) {
return res.status(200)
} )
/* Post new comment. */
router.post("/new", function (req, res, next) {
return res.status(200)
});
//Update comments
router.put("/update", function (req, res, next) {

})
module.exports = router;

索引/路由运行良好，但/auth和/注释不正常。

我正在尝试获取http://localhost:3000/comments

.status()不会结束响应过程。您需要通过链接其他方法(如.end()或.send()(来显式结束它。

用这样的东西更新/comments的GET路由。

router.get("/", function (req, res, next) {
return res.status(200).end();
})
