I'm writing a web app with a separate frontend and backend. The frontend is written in React, and the backend is a node.js server running an Express endpoint. How do I ensure that only my frontend can access the API, and not anyone else? My API URL is exposed in my frontend client side code, so anyone can see that. I added JWT authentication to my API, but I still need to have an unprotected /login endpoint in order to generate the JWT token, and in order to login to generate the token, I must post both a username and password from my frontend, which other users can see, since it's done from

I'm writing an android application which needs to read user's fitness data (steps, calories, etc) from a back end server. this server will read the data and push notifications to android app if necessary. I managed to get the authentication part done and app is now sending the code recevied from oauth flow to the backend server (followed this example) and the server successfully exchanges the code access and refresh tokens. The problem is I did not find any resource on how to access the fitness data from a backend server in the google samples. I found the library <dependency> <groupId>com

Backend servers varnish有"后端"或者"源"服务器的概念。backend server提供给varnish加速的内容。 第一步设置是告诉varnish从哪儿找到backend server。使用你喜欢的编辑器打开varnishd引入的VCL文件。 VCL文件的开头有一小段有点像这样： # backend default { # .host = "127.0.0.1"; # .port = "8080"; # } 去掉注释后 backend default { .host = "127.0.0.1"; .port = "8080"; } 这样一段配置在varnish中定义了一个后端，被叫做default。（和c的函数定义有点相似），当varnish需要从后端获得内容时，它将连接127.0.0.1的8080端口。 varnish可以定义多个后端，也可以将几个后端放在一个后端集群里面已达到负载均衡的目的。 Multiple backends 某些情况下你可能需要让varnish缓存多个后端的内容。你可能想让varnish映射所有的url在单个后端上，或者是多个后端。这里有些参数可以满足这样的需求。 现在我们需要在PHP站点中引入java应用。java应用的链接都是以/java/开头的。 处理java应用的服务器监听在8000端口上。默认的default

In Emacs, I have installed the MELPA company-irony-c-header package. I then did some research on the web, and apparently in order to configure the package, what I took to mean "activating" it, I had to add this: (defun company-my-backend (command &optional arg &rest ignored) (interactive (list 'interactive)) (case command (interactive (company-begin-backend 'company-my-backend)) (prefix (when (looking-back "foo\\>") (match-string 0))) (candidates (when (equal arg "foo") (list "foobar" "foobaz" "foobarbaz"))) (meta (format "This value is named %s" arg)))) into something called a " back-end "
