如何在livedata协程中调用函数

Question

如何多次在liveData协程中调用内部方法

我想每次调用此函数时都调用这部分代码：

    try {
        emit(LiveDataResult.Success(configApi.getConfig(ConfigurationRequest())))
    } catch (exception: Exception) {
        emit(LiveDataResult.Failure(exception.message, exception))
    }

在此功能中：

 fun getConfig(): LiveData<LiveDataResult<ConfigurationResponse>?> {
    return liveData<LiveDataResult<ConfigurationResponse>?>(dispatcher.IO) {
        emit(
            LiveDataResult.Success(
                cacheHelper.getApiResponse(
                    GET_CONFIG,
                    ConfigurationResponse::class.java
                )
            )
        )
        try {
            emit(LiveDataResult.Success(configApi.getConfig(ConfigurationRequest())))
        } catch (exception: Exception) {
            emit(LiveDataResult.Failure(exception.message, exception))
        }
    }
}
