[英]What protocol does an app server and nginx communicate through?
Background: Imagine you have a web app with this architecture: A Node App Server(Koa) and an Nginx Web Server in front. 背景:假设您有一个具有以下架构的Web应用程序:前面有一个Node App Server(Koa)和一个Nginx Web Server。
Scenario: Client browser makes a request to Server. 场景:客户端浏览器向服务器发出请求。 It gets picked up by nginx and sent through to app server and app server responses back to nginx and nginx response back to client.
它被nginx拾取并发送到应用服务器,应用服务器响应返回给nginx,nginx响应返回给客户端。
Question: From this interaction, What are the protocols at each request and response? 问题:通过这种交互,每个请求和响应都有哪些协议? Do you configure them, is it http/1 or 1.1 or 2?
您是否配置它们,是http / 1还是1.1或2? is it tcp/ip
tcp / ip
Browser Request: TCP/IP ??? 浏览器请求:TCP / IP ??? Nginx Request: ???
Nginx请求:??? App Server Response: ???
应用服务器响应:??? Nginx Request: ???
Nginx请求:???
What protocol does an app server and nginx communicate through?
应用服务器和Nginx通过什么协议进行通信?
Whatever protocol you've configured. 无论您配置了什么协议。
Imagine you have a web app with this architecture: A Node App Server(Koa) and an Nginx Web Server in front.
假设您有一个具有此体系结构的Web应用程序:前面有一个Node App Server(Koa)和一个Nginx Web Server。
Your Koa app is going to use HTTP. 您的Koa应用将使用HTTP。 Therefore, HTTP is used between Nginx and your app server.
因此,在Nginx和您的应用服务器之间使用HTTP。
Browser Request: TCP/IP ???
浏览器请求:TCP / IP ???
HTTP is always ran over TCP. HTTP始终通过TCP运行。 The browser will use whichever version of HTTP is supported by itself and the server.
浏览器将使用自身和服务器支持的HTTP版本。
Do you configure them, is it http/1 or 1.1 or 2?
您是否配置它们,是http / 1还是1.1或2?
Yes, you configure it. 是的,您配置它。 Although, Node.js doesn't support HTTP/1.0 properly.
虽然,Node.js不正确支持HTTP / 1.0。 And, HTTP/2 is typically terminated by your web server (Nginx in this example).
并且,HTTP / 2 通常由您的Web服务器(在此示例中为Nginx)终止。 So, it's typical that HTTP/1.1 is used between Nginx and your Node.js app server.
因此, 通常在Nginx和Node.js应用服务器之间使用HTTP / 1.1。 This, obviously, can change if you change it.
显然,如果您进行更改,它可能会更改。
