[Nancy on. Net Core Docker] Lightweight web framework

. NET core is now a big development, although I am now engaged in Python development, but has been concerned about the development of. NET, in the blog park, when we find that everyone will mention the framework of Nancy, after simple use, found that it is so simple and elegant

public class samplemodule:nancy.nancymodule{public    samplemodule ()    {        get["/"] = _ = "Hello world!";    }}

The code has been uploaded to git, including source code and docker packaging scripts, and you are interested in self-study

This is similar to the flask in Python and is easy to use. Today we're going to make a very easy-to-use. NET Core version of the Nancy app, then package the program into Docker and publish and use it.

• Development environment: Marc Pro
• Ide:vscode
• . Net Core
• Docker

Before the development, please ensure that the above environment has been installed

1. Create a folder Webapi execute a command

dotnet New

2. After the implementation will be the first to make some necessary documents, open the Package.json, the following content copied into

{  "version":"1.0.0-*",  "buildoptions": {    "Debugtype":"Portable",    "Emitentrypoint": true},"Dependencies": {    "Microsoft.NETCore.App": {      "version":"1.0.0",      "type":"Platform"    },    "Microsoft.AspNetCore.Server.Kestrel":"1.0.0",    "Microsoft.AspNetCore.Owin":"1.0.0",    "Nancy":"2.0.0-barneyrubble"  },  "commands": {    "Web":"Microsoft.AspNet.Server.Kestrel"  },  "Frameworks": {    "netcoreapp1.0": {}  }}

3. OK. Vscode will automatically import the relevant DLL file when it is saved, we'll create the StartUp.cs file after the successful introduction.

using Microsoft.AspNetCore.Builder; using Nancy.owin; namespace nancyapplication{    publicclass  Startup    {        public void Configure (Iapplicationbuilder app)        {            = = x.usenancy ())        ;     }}}

4. Create a HomeModel.cs file after saving

usingNancy;namespacenancyapplication{ Public classHomemodule:nancymodule { PublicHomemodule () {Get ("/", args ="Hello World, it's Nancy on. NET Core"); }    }     Public classPagemodule:nancymodule { PublicPagemodule () {Get ("/person/{name}", args =NewPerson () {Name =args.name}); }    }     Public classPerson { Public stringName {Get;Set; } }}

Routing and Return values have been written, I do not explain the relevant code here, interested in the self-knowledge can be

4. Edit the Program.cs file

usingSystem.IO;usingMicrosoft.AspNetCore.Builder;usingMicrosoft.AspNetCore.Hosting;namespacenancyapplication{ Public classProgram { Public Static voidMain (string[] args) {            varHost =NewWebhostbuilder (). Usecontentroot (Directory.GetCurrentDirectory ()). Usekestrel (). Useurls ("http://*:5000")                . Usestartup<Startup>()                .             Build (); Host.        Run (); }    }}

5. OK, the necessary files are ready, then run the dotnet run, access http://127.0.0.1:5000 to see the results,

6. Using Docker to deploy programs

To access our API address:

±|master?:1 ? | →curl http://127.0.0.1:5000/person/bruce{"name":"  Bruce"}

Program and code I have been packaged into git, there are related instructions, the program is easily packaged into Docker, so it can be easily clustered or deployed.
