Using app.set to set trust proxy

由 假如想象 提交于 2020-03-04 06:47:28
问题 When setting the application variable trust proxy , does the second argument in app.set mean that the server trusts all the requests FROM 127.0.0.1 or TO 127.0.0.1? For example: app.set('trust proxy', 'loopback'); // or app.set('trust proxy', '127.0.0.1'); and then var sess = { proxy: true cookie: { httpOnly: true, secure: true } } According to the documentation, several types of value are allowed as the second argument: Boolean If true, the client’s IP address is understood as the left-most

Express app - Change base url

由 对着背影说爱祢 提交于 2020-03-03 05:50:07
问题 I'm building a Q&A app following this tutorial and everything goes well, but I need to change the chance to change the base root where the app is being served via config files. Now the app is served in localhost:8080 and I need to be served over localhost:8080/qae (for example). I think the answer is near this piece of code: // Setup server var app = express(); var server = http.createServer(app); var socketio = require('socket.io')(server, { serveClient: config.env !== 'production', path: '

用n多的框架写同一个demo

由 我只是一个虾纸丫 提交于 2020-02-29 17:27:41
发表日期2016年年末 最近有了比较长的空闲时间。 所以看了很多很多不同的语言，框架。 java用了很多年了，总觉得眼界都被java影响了，所以想从新开始学一点新的东西。 而一旦开始选择开始的路径，完美主义的小心思就出来作祟了。 泛泛的接触了好多好多东西，基本上主流的语言，框架都把入门文档看了个遍。 到最后都没有达到最初想学点东西的目的，反而看文档的能力提高不少...... 所以，我决定不再单纯的看了。 我觉得执行下面的计划，动手写写。这也是为什么文章开始就要写明发表时间，因为未来会发生什么谁也不知道，我得到的结果只是当下我认为的好结果而已。 仅此而已 测试方式：controller层上返回服务器当前时间 new Date（）.getTime() //long类型 开发方式：使用各个框架的引导教程默认设置去写代码，尽量写最少的代码完成demo 测试的框架：jfinal（java），grails（groovy），play（scala），springboot-undertow（java），express（js），beego（golang），compojure（clojure）....看情况增加 测试内容：ab进行压测测试，开发效率（完成所花费的时间），上手难度，扩展性（面对需求频繁更改的可维护性） 压测命令：ab -n 100000 -c 1000 -k http:/

How to properly do a createReactionCollection

由 ↘锁芯ラ 提交于 2020-02-29 06:55:29
问题 I've been wanting to create an event when a user presses a reaction that is a Check or X. Although, when I use the function I get an error that it doesn't exist for the message object. I've already from awaitReactions back to this and it hasn't worked. EDIT: I did a console.log to the messageSent object and I got this Promise { <pending> } var messageSent = user.send({embed}) .then(function (message) { message.react('✅') message.react('❎') }); messageSent.createReactionCollection(r => ['✅','❎

Express js redirect with cookie, cookie not present

由 。_饼干妹妹 提交于 2020-02-28 06:30:14
问题 So I've implemented facebook login using Passport-js. I've also implemented Cookie-strategy for using good ole username/password login. My setup is Express-js backend and a React front-end. Backend and frontend runs on different servers and domains(backend-client.com, frontend-client.com). Everything works like a charm on localhost but not in stage and production environment. Don't know if it matters but I'm using Heroku for hosting my applications. The issue: When the facebook authentication

Rate limiting for Google/Firebase cloud functions?

由 感情迁移 提交于 2020-02-27 08:27:20
问题 I am using Firebase to develop an app that uses Cloud Functions as a REST API internally. My question is, is there an easy way to implement per-IP/per-user rate-limiting similar to what slack uses, except on a per-IP and per-user basis, rather than per-app (since it's all one app). Optional support for small bursts is preferable as well. Example code (see the // TODO: comments): exports.myCoolFunction = functions.https.onRequest((req, res) => { // TODO: implement IP rate-limiting here

Express - better pattern for passing data between middleware functions

由 淺唱寂寞╮ 提交于 2020-02-27 07:10:00
问题 I just brought up this issue with Express and I am interested in what StackOverflow thinks about it: https://github.com/strongloop/express/issues/2831 my question is why Express opts to disallow the developer from passing data directly between middleware functions and basically forces you to assign temporary data to the request object in what I have always considered to be a quite awkward assignment. to be more specific: passing data between middleware functions usually involves doing this
