使用VisualStudio代码文本编辑器在mongodb（node.js）中实现搜索功能

node.js mongodb visual-studio-code

使用VisualStudio代码文本编辑器在mongodb（node.js）中实现搜索功能,node.js,mongodb,visual-studio-code,full-text-search,partial,Node.js,Mongodb,Visual Studio Code,Full Text Search,Partial,我在前端（userlist.ejs）中完成了搜索功能，但我不知道如何在mongodb中执行搜索功能，也不知道如何从mongodb获取数据，但我将文档从mongodb（index.js，变量为“userlist”）传递到前端（userlist.ejs）。我在下面附上我的代码，请找到它并解决我的问题在这里，我附上app.js的代码 var createError = require('http-errors'); var express = require('express'); var path

我在前端（userlist.ejs）中完成了搜索功能，但我不知道如何在mongodb中执行搜索功能，也不知道如何从mongodb获取数据，但我将文档从mongodb（index.js，变量为“userlist”）传递到前端（userlist.ejs）。我在下面附上我的代码，请找到它并解决我的问题

在这里，我附上app.js的代码

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');

// New Code
var monk = require('monk');
var db = monk('localhost:27017/nodetest1');

var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');

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')));

// Make our db accessible to our router
app.use(function(req,res,next){
  req.db = db;
  next();
});

app.use('/', indexRouter);
app.use('/users', usersRouter);

// 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;

这里是我的index.js文件

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

/* GET Userlist page. */
router.get('/userlist', function(req, res) {
  var db = req.db;
  var collection = db.get('cust');
  collection.find({},{},function(e,docs){
      res.render('userlist', {
          "userlist" : docs
      });
  });
})
module.exports = router;

这是我的userlist.ejs文件
