# AndroidServer

基于 Kotlin + Netty 开发，为 Android 系统提供 Web Server 的功能，包括 Http、TCP、WebSocket
# 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
Gradle:
```groovy
implementation 'com.safframework.server:android-server-core:<latest-version>'
```
```groovy
implementation 'com.safframework.server:android-server-converter-gson:<latest-version>'
```
# Usage:
## Http 服务
通过使用 Service 来启动一个 http 服务，它的 http 服务本身支持 rest 风格、支持跨域、cookies 等。
```kotlin
class HttpService : Service() {
private lateinit var androidServer: AndroidServer
override fun onCreate() {
super.onCreate()
startServer()
}
// 启动 Http 服务端
private fun startServer() {
androidServer = AndroidServer.Builder{
converter {
GsonConverter()
}
logProxy {
LogProxyImpl
}
}.build()
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(this,"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 {
L.d("before....")
return true
}
override fun after(request: Request, response: Response) {
L.d("after....")
}
})
.start()
}
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
return super.onStartCommand(intent, flags, startId)
}
override fun onDestroy() {
androidServer.close()
super.onDestroy()
}
override fun onBind(intent: Intent): IBinder? {
return null
}
}
```
测试：
```
curl -v 127.0.0.1:8080/hello
* Trying 127.0.0.1...
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> GET /hello HTTP/1.1
> Host: 127.0.0.1:8080
> User-Agent: curl/7.50.1-DEV
> Accept: */*
>
< HTTP/1.1 200 OK
< server: monica
< content-type: text/plain
< content-length: 11
<
* Connection #0 to host 127.0.0.1 left intact
hello world
```
```
curl -v -d 测试 127.0.0.1:8080/uploadLog
* Trying 127.0.0.1...
* Connected to 127.0.0.1 (127.0.0.1) port 8080 (#0)
> POST /uploadLog HTTP/1.1
> Host: 127.0.0.1:8080
> User-Agent: curl/7.50.1-DEV
> Accept: */*
> Content-Length: 6
> Content-Type: application/x-www-form-urlencoded
>
* upload completely sent off: 6 out of 6 bytes
< HTTP/1.1 200 OK
< server: monica
< content-type: text/plain
< content-length: 6
<
* Connection #0 to host 127.0.0.1 left intact
测试
```
## Socket 服务
Socket 服务，AndroidServer 支持同一个端口同时提供 TCP/WebSocket 服务
```kotlin
class SocketService : Service() {
private lateinit var androidServer: AndroidServer
override fun onCreate() {
super.onCreate()
startServer()
}
// 启动 Socket 服务端
private fun startServer() {
androidServer = AndroidServer.Builder{
port {
8888
}
converter {
GsonConverter()
}
logProxy {
LogProxy
}
}.build()
androidServer
.socket("/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()
}
override fun onStartCommand(intent: Intent?, flags: Int, startId: Int): Int {
return super.onStartCommand(intent, flags, startId)
}
override fun onDestroy() {
androidServer.close()
super.onDestroy()
}
override fun onBind(intent: Intent): IBinder? {
return null
}
}
```
Socket 服务可以使用 ：https://github.com/fengzhizi715/NetDiagnose 进行测试
# TODO List：
* Android 上性能的优化
* 完善 Android.Builder 类
* 支持 HttpSession
* 支持 Https
* 支持 HTTP/2
