ktor封装

代码如下：

object KtorClient {
//    private const val BASE_URL = "http://***.**.***.62:8002"
    private const val BASE_URL = "https://mock.***.cn"

    val client = HttpClient(CIO) {
        install(ContentNegotiation) {
            json(Json {
                prettyPrint = true
                isLenient = true
            })
        }

        install(HttpTimeout) {
            requestTimeoutMillis = 10000
        }
        install(Logging) {
            logger = Logger.DEFAULT
            level = LogLevel.NONE
        }
        install(DefaultRequest) {
            url(BASE_URL)
        }
//        install(HttpRequestRetry) {
//            maxRetries = 1
//            retryIf { request, response ->
//                response.status.value in listOf(408, 429, 500, 502, 503)
//            }
//            retryOnExceptionIf { _, exception ->
//                exception is SocketTimeoutException || exception is ConnectException || exception is UnresolvedAddressException
//            }
//            delayMillis { retry ->
//                retry * 3000L
//            }
//        }
    }

    fun close() {
        client.close()
    }

    inline fun <reified T> get(url: String, params: Map<String, String> = emptyMap()): Flow<T> {
        return flow {
            val response = client.get(url) {
                params.forEach { parameter(it.key, it.value) }
            }
            val result = response.body<T>()
            emit(result)
        }.catch { throwable: Throwable ->
            throw throwable
        }.onCompletion { cause ->
            close()
        }.flowOn(Dispatchers.IO)
    }

    inline fun <reified T> post(url: String, params: Map<String, String> = emptyMap()): Flow<T> {
        return flow {
            val response = client.post(url) {
                params.forEach { parameter(it.key, it.value) }
            }
            val result = response.body<T>()
            emit(result)
        }.catch { throwable: Throwable ->
            throw throwable
        }.onCompletion { cause ->
            close()
        }.flowOn(Dispatchers.IO)
    }
}

请求：

Log.e("TAG", "111开始请求网络")
                KtorClient.get<BaseResponse<List<String>>>(
                    "m1/****/api/user",
                    hashMapOf("id" to "1")
                ).collect {
                    Log.e("TAG", "请求结果=》$it")
                }
