AndroidServer
基于 Kotlin + Netty 开发，为 Android App 提供 Server 的功能，包括 Http、TCP、WebSocket 服务
Feature:
- 支持 Http、TCP、WebSocket 服务
- 支持 Rest 风格的 API、文件上传、下载
- 支持加载静态网页
- Http 的路由表、全局的 HttpFilter 均采用字典树(Tried Tree)实现
- 日志隔离，开发者可以使用自己的日志库
- core 模块只依赖 netty-all，不依赖其他第三方库

下载安装
将它添加到项目的 root build.gradle 中：
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Gradle:
implementation 'com.github.fengzhizi715.AndroidServer:core:<latest-version>'implementation 'com.github.fengzhizi715.AndroidServer:gson:<latest-version>'Usage:
搭建 Http 服务
AndroidServer 的 http 服务本身支持 rest 风格、支持跨域、cookies 等。
fun startHttpServer(context:Context, androidServer:AndroidServer) {
androidServer
.get("/hello") { _, response: Response ->
response.setBodyText("hello world")
}
.get("/sayHi/{name}") { request, response: Response ->
val name = request.param("name")
response.setBodyText("hi $name!")
}
.post("/uploadLog") { request, response: Response ->
val requestBody = request.content()
response.setBodyText(requestBody)
}
.get("/downloadFile") { request, response: Response ->
val fileName = "xxx.txt"
File("/sdcard/$fileName").takeIf { it.exists() }?.let {
response.sendFile(it.readBytes(),fileName,"application/octet-stream")
}?: response.setBodyText("no file found")
}
.get("/test") { _, response: Response ->
response.html(context,"test")
}
.fileUpload("/uploadFile") { request, response: Response -> // curl -v -F "file=@/Users/tony/1.png" 10.184.18.14:8080/uploadFile
val uploadFile = request.file("file")
val fileName = uploadFile.fileName
val f = File("/sdcard/$fileName")
val byteArray = uploadFile.content
f.writeBytes(byteArray)
response.setBodyText("upload success")
}
.filter("/sayHi/*", object : HttpFilter {
override fun before(request: Request): Boolean {
LogManager.d("HttpService","before....")
return true
}
override fun after(request: Request, response: Response) {
LogManager.d("HttpService","after....")
}
})
.start()
}测试：
curl -v 127.0.0.1:8080/hello

搭建 WebSocket 服务
AndroidServer 支持提供 WebSocket 服务
fun startWebSocketServer(androidServer:AndroidServer) {
androidServer
.websocket("/ws",object : SocketListener<String>{
override fun onMessageResponseServer(msg: String, ChannelId: String) {
LogManager.d("WebSocketService","msg = $msg")
}
override fun onChannelConnect(channel: Channel) {
val insocket = channel.remoteAddress() as InetSocketAddress
val clientIP = insocket.address.hostAddress
LogManager.d("WebSocketService","connect client: $clientIP")
}
override fun onChannelDisConnect(channel: Channel) {
val ip = channel.remoteAddress().toString()
LogManager.d("WebSocketService","disconnect client: $ip")
}
})
.start()
}测试：
curl -v \
--include \
--no-buffer \
--header "Connection: Upgrade" \
--header "Upgrade: websocket" \
--header "Host: echo.websocket.org" \
--header "Origin: https://echo.websocket.org" \
--header "Sec-WebSocket-Key: NVwjmQUcWCenfWu98asDmg==" \
--header "Sec-WebSocket-Version: 13" \
http://127.0.0.1:8080/ws
GET /ws HTTP/1.1
Host: echo.websocket.org
User-Agent: curl/7.67.0
Accept: */*
Connection: Upgrade
Upgrade: websocket
Origin: https://echo.websocket.org
Sec-WebSocket-Key: NVwjmQUcWCenfWu98asDmg==
Sec-WebSocket-Version: 13
HTTP/1.1 101 Switching Protocols
upgrade: websocket
connection: upgrade
sec-websocket-accept: oPhRcOTYgRvrC0D+cTPcN3XYC1k=
Socket/WebSocket 服务可以使用 ：https://github.com/fengzhizi715/NetDiagnose 进行测试。 上述 websocket 服务默认的 endpoint：ws://ip:port/ws
搭建 Socket 服务
AndroidServer 支持单独提供 Socket 服务，也支持一个端口同时提供 Socket/WebSocket 服务。
使用 androidServer 的 socketAndWS()，同时提供 Socket/WebSocket 服务：
fun startSocketServer(androidServer:AndroidServer) {
androidServer
.socketAndWS("/ws", object: SocketListener<String> {
override fun onMessageResponseServer(msg: String, ChannelId: String) {
LogManager.d("SocketService","msg = $msg")
}
override fun onChannelConnect(channel: Channel) {
val insocket = channel.remoteAddress() as InetSocketAddress
val clientIP = insocket.address.hostAddress
LogManager.d("SocketService","connect client: $clientIP")
}
override fun onChannelDisConnect(channel: Channel) {
val ip = channel.remoteAddress().toString()
LogManager.d("SocketService","disconnect client: $ip")
}
})
.start()
}androidServer 的 socket() 单独提供 Socket 服务。
TODO List：
- 提供默认的 TCP 服务
- 支持 Https
- 反向代理
- 支持 HTTP/2
