功能演示

项目包含三个主要功能演示页面：

1. Flow风格请求 (FlowRequestActivity)

  • 基础响应式请求（BaseResponse格式）
  • 对象响应式请求（直接解析为对象）
  • 字符串响应式请求（原始数据）
  • 组合多个API请求

2. 挂起函数风格请求 (SuspendRequestActivity)

  • 传统挂起函数方式请求
  • 同步风格的数据获取
  • 多请求组合处理

3. 文件操作 (FileOperationActivity)

  • 文件选择和上传
  • 普通文件下载
  • 断点续传下载
  • 文件信息获取

使用说明

0.快速引用

repositories {...maven(url = "https://gitee.com/laujiangtao/maven-repo/raw/main/")...
}

dependencies {...implementation("me.laujiangtao.net:easynet:1.0.0")...
}

1. 初始化网络库

在Application中初始化网络模块：
多服务器配置

class MyApplication : Application() {override fun onCreate() {super.onCreate()// 初始化网络模块val server1Config = HttpConfig(serverUrl = server1Url, cacheDir = cacheDir)HttpClient.init(server1Url, server1Config)// 初始化网络模块val server2Config = HttpConfig(serverUrl = server2Url)HttpClient.init(server2Config)// 初始化网络模块HttpClient.init(server3Url)}
}

2. 定义API接口

/*** @author jiangtao on 2025/9/20* 网络请求API接口定义* 定义了应用程序所需的各种网络请求方法*/
interface ApiService {/*** 查询域名的Whois信息* @param domain 域名参数* @return 返回封装了Whois信息的BaseResponse对象*/@GET("/api/whois")@Cacheable(ttl = 30 * 1000,strategy = CacheStrategy.CACHE_FIRST,includeQueryParams = true)suspend fun whois(@Query("domain") domain: String): BaseResponse<Whois?>?/*** 查询城市天气信息* @param city 城市名称参数* @return 返回天气信息对象*/@GET("/api/weather")suspend fun tianqi(@Query("city") city: String): Tianqi/*** 获取美女图片信息（示例接口）* @return 返回任意类型的数据*/@GET("/api/pcmeinvpic")suspend fun pcmeinv(): Any?
}

2.1 动态添加请求头

interface ApiService {@Headers("X-Force-Network: true")@GET("users")suspend fun getUsersForceNetwork(): BaseResponse<List<User>>
}

interface ApiService {@GET("users")suspend fun getUsers(@Header("X-Force-Network") forceNetwork: Boolean = false): BaseResponse<List<User>>
}// 使用时强制从网络获取
apiService.getUsers("true")

3. 创建Repository

/*** @author jiangtao on 2025/9/20* 网络请求仓库类* 继承自NetRepository，提供应用程序所需的网络请求方法* 包含Flow风格和普通挂起函数风格的网络请求方法*/
class MyNetworkRepository : NetworkRepository {/*** 创建单个实例*/private val service = RetrofitClient.create(server1Url)private val apiService1 = service.createService(ApiService::class.java)private val apiService2 = service.createService<ApiService>()//请求返回非json数据private val apiService3 = service.createService<ApiService>(false)/*** 通过 HttpClient 从 Application创建的实例获取*/// 注入具体的API服务private val apiService: ApiService = HttpClient.createService(server1Url)//用于请求返回非json数据private val rawApiService = HttpClient.createService<RawApiService>(server1Url, false)private val fileApiService = HttpClient.createService(server1Url, FileApiService::class.java)// ===================================================================// Flow 风格的网络请求方法// ===================================================================/*** 查询域名信息* @param domain 域名* @return 返回包含Whois信息的Flow*/fun whois(domain: String): Flow<FlowResult<BaseResponse<Whois?>?>> = apiCall {apiService.whois(domain)}/*** 查询天气信息* @param city 城市名* @return 返回包含天气信息的Flow*/fun tianqi(city: String): Flow<FlowResult<Tianqi?>> {return apiCall {apiService.tianqi(city)}}/*** 获取美女图片接口（示例接口）* @return 返回图片数据的Flow*/fun pcmeinv(): Flow<FlowResult<String?>> {return apiCall {rawApiService.pcmeinv()}}// ===================================================================// 普通挂起函数风格的网络请求方法// ===================================================================/*** 同步风格的挂起函数 - 查询域名信息* @param domain 域名* @return 返回Whois信息的BaseResponse包装对象*/suspend fun getWhoIsInfo(domain: String): BaseResponse<Whois?>? {// 这里应该是实际的 API 调用return apiService.whois(domain)}/*** 同步风格的挂起函数 - 查询天气信息* @param city 城市名* @return 返回天气信息对象*/suspend fun getTianqiInfo(city: String): Tianqi? {// 这里应该是实际的 API 调用return apiService.tianqi(city)}/*** 同步风格的挂起函数 - 获取美女图片接口* @return 返回图片数据字符串*/suspend fun getPcmeinvInfo(): String? {// 这里应该是实际的 API 调用return rawApiService.pcmeinv()}suspend fun fetchMultipleDataDirect(domain: String, city: String): MultipleDataResult {// 并行执行所有API调用val whoisResult = apiService.whois(domain)val tianqiResult = apiService.tianqi(city)val pcmeinvResult = rawApiService.pcmeinv()// 等待所有结果val whoisData = whoisResult?.dataval tianqiData = tianqiResultval pcmeinvData = pcmeinvResult// 组合结果并返回return MultipleDataResult(whoisData, tianqiData, pcmeinvData)}/*** 合并多个网络请求结果的Flow方法*/fun fetchMultipleData(domain: String, city: String): Flow<FlowResult<MultipleDataResult?>> =combineApiCalls({ getWhoIsInfo(domain) },{ getTianqiInfo(city) },{ getPcmeinvInfo() },// ... 可以继续添加更多API调用) { results ->// 在这里处理所有结果并组合成最终数据val data1 = results[0] as? BaseResponse<Whois?>?val data2 = results[1] as? Tianqival data3 = results[2]// ... 处理其他结果MultipleDataResult(data1?.data, data2, data3)}/*** 使用Flow方式合并多个网络请求结果*/fun fetchMultipleDataWithFlow(domain: String,city: String): Flow<FlowResult<MultipleDataResult>> =combineFlows(whois(domain),tianqi(city),pcmeinv(),// ... 添加更多Flow) { results ->// 在这里处理所有结果并组合成最终数据val data1 = results[0] as? BaseResponse<Whois?>?val data2 = results[1] as? Tianqival data3 = results[2]// ... 处理其他结果MultipleDataResult(data1?.data, data2, data3)}fun uploadFile(request: FileUploadBean): Flow<FlowResult<String?>> {return apiCall {fileApiService.upload(request.build())}}/*** 普通文件下载* @param fileUrl 文件下载地址* @return Flow<FlowResult<ResponseBody>> 返回文件流的Flow*/fun downloadFile(fileUrl: String): Flow<FlowResult<ResponseBody?>> {return apiCall {fileApiService.downloadFile(fileUrl)}}/*** 带参数的文件下载* @param fileUrl 文件下载地址* @param params 下载参数* @return Flow<FlowResult<ResponseBody>> 返回文件流的Flow*/fun downloadFileWithParams(fileUrl: String,params: Map<String, String>): Flow<FlowResult<ResponseBody?>> {return apiCall {fileApiService.downloadFileWithParams(fileUrl, params)}}/*** 断点续传下载* @param fileUrl 文件下载地址* @param startByte 开始下载的字节位置* @return Flow<FlowResult<ResponseBody>> 返回文件流的Flow*/fun downloadFileWithResume(fileUrl: String,startByte: Long = 0): Flow<FlowResult<ResponseBody?>> {return if (startByte > 0) {// 断点续传val rangeHeader = "bytes=$startByte-"apiCall {fileApiService.downloadFileWithRange(fileUrl, rangeHeader)}} else {// 普通下载apiCall {fileApiService.downloadFile(fileUrl)}}}/*** 获取文件信息（用于断点续传前检查）* @param fileUrl 文件地址* @return Flow<FlowResult<Response>> 返回响应信息的Flow*/fun getFileInfo(fileUrl: String): Flow<FlowResult<Response?>> {return apiCall {fileApiService.getFileInfo(fileUrl)}}
}

4. 在ViewModel中使用

/*** @author jiangtao on 2025/9/20*/
class MyViewModel : ViewModel() {private val repository = MyNetworkRepository()// ===================================================================// Flow 风格的网络请求方法// ===================================================================fun getWhoIs(domain: String, cb: ((resp: FlowResult<BaseResponse<Whois?>?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.whois(domain).collect { result ->cb?.invoke(result)}}}fun getTianqi(city: String, cb: ((resp: FlowResult<Tianqi?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.tianqi(city).collect { result ->cb?.invoke(result)}}}fun getPcmeinvpic(cb: ((resp: FlowResult<String?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.pcmeinv().collect { result ->cb?.invoke(result)}}}// ===================================================================// 普通挂起函数风格的网络请求方法// ===================================================================// 提供同步风格的挂起函数suspend fun getWhoIsSuspend(domain: String): BaseResponse<Whois?>? {return try {// 这里使用 withContext 确保在 IO 线程执行网络请求withContext(Dispatchers.IO) {// 实际调用 API 获取 whois 信息repository.getWhoIsInfo(domain)}} catch (e: Exception) {// 记录错误日志Log.e("UserViewModel", "获取WhoIs信息失败", e)null // 返回 null 表示失败}}suspend fun getTianqiSuspend(city: String): Tianqi? {return try {withContext(Dispatchers.IO) {repository.getTianqiInfo(city)}} catch (e: Exception) {Log.e("UserViewModel", "获取天气信息失败", e)null}}suspend fun getPcmeinvpicSuspend(): String? {return try {withContext(Dispatchers.IO) {repository.getPcmeinvInfo()}} catch (e: Exception) {Log.e("UserViewModel", "获取PC妹纸图片失败", e)null}}// ===================================================================// Flow 风格的多个网络请求合并// ===================================================================suspend fun fetchMultipleDataDirect(domain: String, city: String): MultipleDataResult? {return try {withContext(Dispatchers.IO) {repository.fetchMultipleDataDirect(domain, city)}} catch (e: Exception) {Log.e("UserViewModel", "获取PC妹纸图片失败", e)null}}// 使用 combineResults 方法合并多个网络请求fun fetchMultipleData(domain: String,city: String,cb: ((resp: FlowResult<MultipleDataResult?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.fetchMultipleData(domain, city).collect { result ->cb?.invoke(result)}}}// 使用 combineResultsWithFlow 方法合并多个网络请求fun fetchMultipleDataWithFlow(domain: String,city: String,cb: ((resp: FlowResult<MultipleDataResult?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.fetchMultipleDataWithFlow(domain, city).collect { result ->cb?.invoke(result)}}}fun uploadFile(file: File, params: Map<String, String>, cb: ((resp: FlowResult<String?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {val uploadBean = FileUploadBean(file, params)repository.uploadFile(uploadBean).collect { result ->cb?.invoke(result)}}}fun downloadFile(fileUrl: String, cb: ((resp: FlowResult<ResponseBody?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.downloadFile(fileUrl).collect { result ->cb?.invoke(result)}}}fun downloadFileWithParams(fileUrl: String,params: Map<String, String>,cb: ((resp: FlowResult<ResponseBody?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.downloadFileWithParams(fileUrl, params).collect { result ->cb?.invoke(result)}}}fun downloadFileWithResume(fileUrl: String,startByte: Long = 0,cb: ((resp: FlowResult<ResponseBody?>?) -> Unit)? = null) {viewModelScope.launch(CoroutineExceptionHandler { _, _ ->cb?.invoke(null)}) {repository.downloadFileWithResume(fileUrl, startByte).collect { result ->cb?.invoke(result)}}}
}

5. 在Activity中调用

Flow风格网络请求

/*** @author jiangtao on 2025/9/20*/
class FlowRequestActivity : MyBaseActivity<ActivityFlowRequestBinding>() {private val TAG = "FlowRequestActivity"private lateinit var viewModel: MyViewModelprivate var time: Long = 0private var cost: Long = 0override fun setup(savedInstanceState: Bundle?) {viewModel = ViewModelProvider(this)[MyViewModel::class.java]binding.result.movementMethod = ScrollingMovementMethod.getInstance()setOnClick()}private fun setOnClick() {// ===================================================================// Flow 风格的网络请求方法// ===================================================================binding.flowRequestBaseResponse.setOnClickListener {viewModel.getWhoIs("xxhzm.cn") {handlerData(it as FlowResult)}}binding.flowRequestObject.setOnClickListener {viewModel.getTianqi("上海") {handlerData(it as FlowResult)}}binding.flowRequestString.setOnClickListener {viewModel.getPcmeinvpic() {handlerData(it as FlowResult)}}binding.flowRequestCombinedData1.setOnClickListener {viewModel.fetchMultipleData("xxhzm.cn", "上海") {handlerData(it as FlowResult)}}binding.flowRequestCombinedData2.setOnClickListener {viewModel.fetchMultipleDataWithFlow("xxhzm.cn", "上海") {handlerData(it as FlowResult)}}}/*** 简便起见，返回数据统一处理*/override fun <T> handlerData(result: FlowResult<T?>) {result.handle(onSuccess = {hideProgress()showData(it.toString())},onError = { code, message ->hideProgress()showError("错误: $code, $message")},onException = { e ->hideProgress()showError("异常: ${e.message}")},onPrepare = {showProgress()})}private fun showProgress() {time = System.currentTimeMillis()Log.i(TAG, "showProgress")Toast.makeText(this, "showProgress", Toast.LENGTH_SHORT).show()}private fun hideProgress() {cost = System.currentTimeMillis() - timeLog.i(TAG, "hideProgress")Toast.makeText(this, "hideProgress", Toast.LENGTH_SHORT).show()}private fun showData(str: String?) {Log.i(TAG, "showData: $str")binding.result.text = "耗时: $cost ms\n"val jsonObject: JSONObject = JSONObject(str)binding.result.append(jsonObject.toString(4).toString())}private fun showError(message: String) {Log.e(TAG, "showError: $message")Toast.makeText(this, message, Toast.LENGTH_SHORT).show()}
