当我尝试将网络调用从“com.jakewharton.retrofit:retrofit2-kotlin-coroutines-adapter”迁移到内置的改造 2.6 挂起功能时，我遇到了这个问题。

场景，我正在进行多个顺序网络调用以从 API 获取数据。我的第一个电话成功了，没有任何问题，但第二次改造电话。它给了我以下错误。

我在代码中所做的更改，

  1. 从 app.gradle 中删除了适配器库并将我的改造更新到 2.7。
  2. 移除了 await() 调用执行行，并在改造接口方法中添加了“挂起”功能。
  3. 删除了延迟变量改造接口方法。

改造后 2.6

override suspend fun fetchUserProfile() {
        try {
            val result = chilindoAPI.fetchProfile()
            if (result.isSuccessful) {
                _userProfileTable.postValue(result.body())
            }
        } catch (e: HttpExceptionExtended) {
            e.printStackTrace()
        } catch (e: NoConnectivityException) {
            e.printStackTrace()
        }
    }

    override suspend fun fetchCategoriesResponse(domain: String, language: String) {
        try {
            val categoriesRequest = CategoriesRequest()
            categoriesRequest.countryName = domain
            categoriesRequest.language = language
            val result = chilindoAPI.fetchCategories(categoriesRequest)
            if (result.isSuccessful) {
                _categoriesResponse.postValue(result.body())
            }
        } catch (e: HttpExceptionExtended) {
            e.printStackTrace()
            _categoriesResponse.postValue(null)
        } catch (e: NoConnectivityException) {
            e.printStackTrace()
        }
    }

和 API 接口

    @POST(ServiceTypes.USER_PROFILE)
    suspend fun fetchProfile(): Response<UserProfileTable>

    @POST(ServiceTypes.CATEGORIES)
    suspend fun fetchCategories(@Body categoriesRequest: CategoriesRequest): Response<List<CategoriesResponse>>

错误是您的拦截器（com.chilindo.base.network.ChilindoAPIL）在发出另一个请求之前没有关闭响应。这是对旧 OkHttp 版本的无声泄漏；今天它被检测到，所以你可以避免泄漏。
