AndServer

Logo

AndServer is an HTTP and reverse proxy server.

Web server and Web framework of Android platform. It provides annotations like SpringMVC, and if you are familiar with SpringMVC, you can master it very quickly.

  • Static html website deployment.
  • Dynamic http api deployment.
  • Reverse proxy server.

Web Server

Deploy a web server:

Server server = AndServer.webServer(context)
    .port(8080)
    .timeout(10, TimeUnit.SECONDS)
    .build();

// startup the server.
server.startup();

...

// shutdown the server.
server.shutdown();

It also has some features, such as inetAddress(InetAddress), serverSocketFactory(ServerSocketFactory) and sslContext(SSLContext), depending on what you want to achieve.

@RestController
@RequestMapping(path = "/user")
public class UserController {

    @PostMapping("/login")
    public String login(@RequestParam("account") String account,
                        @RequestParam("password") String password) {

        ...
        return "Successful.";
    }

    @GetMapping(path = "/{userId}")
    public User info(@PathVariable("userId") String userId,
                     @QueryParam("fields") String fields) {

        User user = findUserById(userId, fields);
        ...

        return user;
    }

    @PutMapping(path = "/{userId}")
    public void modify(@PathVariable("userId") String userId
                       @RequestParam("age") int age) {
        ...
    }
}

The above code will generate the following two http apis:

POST http://.../user/login
GET http://.../user/uid_001?fields=id,name,age
PUT http://.../user/uid_001

Get connection information with the client:

@GetMapping(path = "/connection")
void getConnection(HttpRequest request, ...) {
    request.getLocalAddr();   // HostAddress
    request.getLocalName();   // HostName
    request.getLocalPort();   // server's port

    request.getRemoteAddr();  // HostAddress
    request.getRemoteHost();  // Especially HostName, second HostAddress
    request.getRemotePort();  // client's port

    ...
}

For documentation and additional information see the website.

Reverse Proxy Server

Deploy a reverse proxy server:

Server server = AndServer.proxyServer()
    .addProxy("www.example1.com", "http://192.167.1.11:8080")
    .addProxy("example2.com", "https://192.167.1.12:9090")
    .addProxy("55.66.11.11", "http://www.google.com")
    .addProxy("192.168.1.11", "https://github.com:6666")
    .port(80)
    .timeout(10, TimeUnit.SECONDS)
    .build();

// startup the server.
server.startup();

...

// shutdown the server.
server.shutdown();

Note: It is just a reverse proxy and does not have the ability to take care of loading balance.

Download

Add the plugin to your project build script :

buildscript {
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.yanzhenjie.andserver:plugin:2.1.9'
        ...
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
...

And then add AndServer dependency to your module:

apply plugin: 'com.yanzhenjie.andserver'

...

dependencies {
    implementation 'com.yanzhenjie.andserver:api:2.1.9'
    annotationProcessor 'com.yanzhenjie.andserver:processor:2.1.9'
    ...
}

If you are using Kotlin, replace annotationProcessor with kapt.
