Express Route 404 错误但路由正确？

Question

我几乎尝试了所有方法，但似乎没有任何效果，请阅读每个教程和 SOF post。一直在抓我的头发。我专门为这条路线收到 404，但我找不到问题。

app.js

var watchRouter = require('./routes/watch');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

// 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('/', indexRouter);
app.use('/search', indexRouter);
app.use('/watch/:anime/:id', watchRouter);

// 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;

watch.js

var router = express.Router();

router.get('/:anime/:id', function(req, res) {
});```

module.exports = router;

Answer 1

由于您在watch.js中的路线是'/:anime/:id'，您需要在app.js中将app.use('/watch/:anime/:id', watchRouter);更改为app.use('/watch', watchRouter);，否则您的完整路线将是'/watch/:anime/:id/:anime/:id'.

因此，例如：

app.js:

app.use('/watch', watchRouter);

watch.js:

router.get('/:anime/:id', (req, res) => {
  return res.json({ anime: req.params.anime, id: req.params.id });
});
