我有这段代码
/* GET */
router.get('/mycol', function(req, res) {
var db = req.db;
var collection = db.get('mycol');
collection.find({}, {}, function(err, docs) {
res.json(docs);
});
});
/* POST */
router.post('/mycol', function(req, res) {
var db = req.db;
var collection = db.get('mycol');
collection.insert({"test":"testing"}, function(err, docs) {
if (err) {
res.json({"error":err});
}
else {
res.json(docs);
}
});
});
GET工作正常,但POST没有 - 插入返回错误,错误json只是:
{"error":{"name":"MongoError"}}
如果我将它输入mongo控制台,完全相同的插入工作正常:
> db.mycol.insert({"test":"testing"})
WriteResult({ "nInserted" : 1 })
我是node.js的新手,到目前为止一切看起来都不错,除了这个......完全坚持下去,不知道该尝试什么
编辑:
这是我的app.js代码,与路由有关吗?也许数据库附加到GET的req对象而不是POST?...
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/skdb');
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.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('/', routes);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;

您需要从MongoError实例生成.message
以诊断您的问题。
http://mongodb.github.io/node-mongodb-native/core/api/MongoError.html
版本问题:
Monk使用MongoDB和Mongoskin 1.4,请参阅package.json: https://github.com/Automattic/monk/blob/master/package.json
您可能需要使用支持更高版本驱动程序的其他模块(例如MongoDB节点包)。
在npm安装修士:
npm WARN peerDependencies The peer dependency mongodb@~1.4 included from mongoskin will no
npm WARN peerDependencies longer be automatically installed to fulfill the peerDependency
npm WARN peerDependencies in npm 3+. Your application will need to depend on it explicitly.
//other stuff
├── mpromise@0.5.1
├── debug@2.2.0 (ms@0.7.1)
├── mongodb@1.4.40 (kerberos@0.0.11, bson@0.2.22)
└── mongoskin@1.4.13

正如Kinetics在评论中所说的 - 只需要查看res.json(err.message)而不仅仅是res.json(错误)
原来我有这个问题:MongoError: driver is incompatible with this server version
