android—ktor-client封装使用，请求网络

ktor-client封装使用步骤：

1.导入依赖：

设置版本号：

java 复制代码

buildscript {
    ext.ktor_version = '2.3.1'
}

添加依赖：

java 复制代码

    implementation "io.ktor:ktor-client-okhttp:$ktor_version"
    implementation "io.ktor:ktor-client-auth:$ktor_version"
    implementation "io.ktor:ktor-client-core:$ktor_version"
    implementation "io.ktor:ktor-client-logging:$ktor_version"
    implementation("io.ktor:ktor-serialization-kotlinx-json:$ktor_version")
    implementation("io.ktor:ktor-client-cio:$ktor_version")
    implementation("io.ktor:ktor-client-content-negotiation:$ktor_version")

2.封装网络工具类：

java 复制代码

class HttpUtils {
    var baseUrl = "https://test.demo.cn"
    val httpClient = HttpClient(OkHttp) {
        install(ContentNegotiation) {
            json(Json {
                prettyPrint = true
                isLenient = true
            })
        }
        install(HttpTimeout) {
            requestTimeoutMillis = 5000
            connectTimeoutMillis = 5000
        }
        install(DefaultRequest) {
            url { baseUrl }
        }
    }

    fun close() {
        httpClient.close()
    }

    inline fun <reified T> get(url: String, params: Map<String, String> = emptyMap()): Flow<T> {
        return flow {
            val response = httpClient.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 = httpClient.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)
    }


}

3.进行请求:

java 复制代码

 private suspend fun testHttpClint(){
        HttpUtils().get<BaseResponse>("", mapOf("id" to "1"))
            .collect{
                it.flag
            }
    }

PS: 网络请求需要放在协程里面使用
