尝试进行第二次网络调用时出现OkHttp Dispatcher IllegalStateException

Question

当我试图将我的网络呼叫从"com.jakeharton.reformit:retrofit2 kotlin coroutines adapter"迁移到内置的reforming 2.6挂起功能时，我遇到了这个问题。

场景中，我正在进行多个连续的网络调用以从API中获取数据。我的第一个电话成功了，没有任何问题，但第二个改装电话。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更新了我的改装至2.7
2. 删除了await((调用执行行，并在改装接口方法中添加了"suspend"函数
3. 删除了延迟变量改造接口方法

我的Logcat控制台

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>>

Answer 1

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