Question

我最近使用本教程为我的Node / Express / Angular项目实现了用户授权模型：https://devdactic.com/restful-api-user-authentication-1/

在我的本地计算机上运行它很有效，但是当我将它上传到我的数字海洋帐户时，到目前为止我已成功托管该项目，我收到了502 Bad Gateway错误。即使我使用直接IP地址和端口。

我在Ubuntu 14上运行它的MEAN实例，并在其他实例上运行其他网站。

我也在该实例上运行Nginx。

我只是不知道如何在我的＆＃34; localhost：3000＆＃34;本地运行应用程序。但是在VH上运行会让我拒绝连接。

我认为问题是＆＃34; bcrypt＆＃34;。由于某种原因，它导致了问题。

有没有人遇到这个以及有关调试的任何建议？

这是我在Nginx日志中看到的内容。据我所知，我没有在这台服务器上使用PHP，但我在那里看到了一个条目。

这是我的user.js文件。当我注释掉对bcrypt的引用时，一切正常。好吧，除了bcrypt方法。所以我知道这与它有关：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var bcrypt = require('bcrypt');

// Thanks to http://blog.matoski.com/articles/jwt-express-node-mongoose/

// set up a mongoose model
var UserSchema = new Schema({
    name: {
        type: String,
        unique: true,
        required: true
    },
    password: {
        type: String,
        required: true
    },
    email:{
        type: String,
        required: true
    }
});

UserSchema.pre('save', function(next) {
    var user = this;
    if (this.isModified('password') || this.isNew) {
        bcrypt.genSalt(10, function(err, salt) {
            if (err) {
                return next(err);
            }
            bcrypt.hash(user.password, salt, function(err, hash) {
                if (err) {
                    return next(err);
                }
                user.password = hash;
                next();
            });
        });
    } else {
        return next();
    }
});

UserSchema.methods.comparePassword = function(passw, cb) {
    bcrypt.compare(passw, this.password, function(err, isMatch) {
        if (err) {
            return cb(err);
        }
        cb(null, isMatch);
    });
};

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

服务器上的网关不良，但使用端口3000不在本地
