Question

我有一个mongolab(mlab)帐户。我正在尝试使用Chrome浏览器中的postman加载项为用户发布数据。我总是得到错误。我无法发布数据。我尝试过其他不同的方式。但没有运气。

是否有人帮我解决这个问题？

这是我的api.js：

var
    User        = require('../models/user'),
    config      = require('../../config'),
    secretKey   = config.secretKey; 


module.exports = function( app, express ) {

    var api = express.Router();

    api.post('/signup', function (req, res) {

        var user = new User({

            name:req.body.name,
            username:req.body.username,
            password:req.body.password

        });

        user.save(function(err){

            if(err){
                res.send(err);
                return;
            }

            res.json({message:'User has been Created!'});
        });
    });


    api.get('/users', function(req, res) {

        User.find({}, function( req, users){
            if(err) {
                res.send(err);
                return;
            }

            res.json(users);
        })

    });

    return api;

}

config.js：

module.exports = {
    "database":"mongodb://xxx:xxxx@ds015700.mlab.com:15700/arifstory",
    "port" : process.env.PORT || 3000,
    "secretKey" : "YourSecretKey"
}

user.js：

var
    mongoose    = require('mongoose'),
    Schema      = mongoose.Schema,
    bcrypt      = require('bcrypt-nodejs');


var UserSchema = new Schema({

    name : String,
    userName:{ type:String, required:true, index : { unique: true }},
    password : { type:String, required : true, select : false }

});

UserSchema.pre('save', function(next) {

    var user = this;

    if(!user.isModified('password')) return next();

    bcrypt.hash( user.password, null, null, function(err, hash) {
        if(err) return next(err);

        user.password = hash;
        next();
    });

});

UserSchema.methods.comparePassword = function( password ) {

    var user = this;

    return bcrypt.compareSync(password, user.password);

}

module.exports = mongoose.model('User', UserSchema);

我真的无法理解这里的问题。请任何人帮助我？

从chrome发送的数据可能未定义。

在api.js文件中的user.save函数上面包含以下2行，在控制台中打印：的console.log（req.body.username）; 的console.log（req.body.password）;

如果显示为未定义，请务必检查＆＃34; x-www-form-urlencoded＆＃34;在＆＃34;身体＆＃34;在Postman中，并提供用户名和密码。
