async-await

问题 I have been trying to understand asynchronous programming, particularly in Python. I understand that asyncio is built off of an event loop which schedules the execution of coroutines, but I have read about several different ways to define coroutines, and I am confused how they all relate to each other. I read this article for more background information on the topic. Although it covers each of the four types of coroutines I have mentioned, it does not entirely describe how they differ.

问题 When I run my app it throws a lot of errors, and the red/yellow error screen on my device, which refreshes automatically and shows me the expected output then. From the log I can see that first my object is return as null, which somehow later updates and I get the output. I have recently started Android Dev (Flutter) I tried to follow a number of online guides and also read related questions on async responses but no troubleshooting has been helping me. My biggest problem being that I can't

问题 I imported a function from an internal utility library that I am unfamiliar with. There is no documentation for this library and I just assumed it was asynchronous due to its name getUserDetails . I thought it was doing an http request. I used it in an async function like this async function getAllUserInfo(event) { const details = await getUserDetails(event); // other stuff } I was wrong in my assumption. A co-worker pointed out that is was not asynchronous. I ended up changing it, but when I

问题 I am working on Dotnet Core Blazor and getting below error while using EventCallBack to bind the parent grid after delete events. Below the code for using Child component <tbody> @foreach (var employee in Employees) { <BlazorAppDemo.Pages.Controls.EmployeeList Employee="employee" ShowFooter="ShowFooter" OnEmployeeSelectionChange="onEmployeeSelectionChanged" btnDeleteClick="OnEmployeeDeleted" > </BlazorAppDemo.Pages.Controls.EmployeeList> } </tbody> EmployeeList child component is below <tr> @

问题 Currently I am developing a Xamarin App which is using IdentityModel.OidcClient to authenticate against my server, and it is being done using the automatic mode presented on the documentation (https://github.com/IdentityModel/IdentityModel.OidcClient2). Everything is working just fine as var result = await client.LoginAsync(); is returning the LoginResult with the AccessToken, etc. What I am trying to figure out is how the backbutton, the recent apps button (both on android) and the close

问题 I've looked at several questions on using async/await with a forEach loop but nothing seems to cover my user case... How can I get the code below to work? Right now I'm getting the following error: await is a reserved word Here's the code: export const fetchUserBookmarks = ( bookmarksIDs ) => async ( dispatch, getState, api ) => { dispatch({ type: 'IS_FETCHING_BOOKMARKS' }); try { bookmarks = []; bookmarksIDs.forEach( bookmarkID => { const bookmark = await api.get( selectedPostByIdEP +

问题 where This is on Linux, Python 3.5.1. what I'm developing a monitor process with asyncio , whose tasks at various places await on asyncio.sleep calls of various durations. There are points in time when I would like to be able to interrupt all said asyncio.sleep calls and let all tasks proceed normally, but I can't find how to do that. An example is for graceful shutdown of the monitor process. how (failed assumption) I thought that I could send an ALRM signal to that effect, but the process
