Medis 是薄雾算法 Mist 的工程实践,其名取自 Mist 和 Redis。薄雾算法是一款性能强到令我惊喜的全局唯一 ID 算法,我将它与业内同样高性能的 Redis 和 Golang 结合到一起,碰撞出了 TPS 为 2.5w/sec 这样超高性能的工程。. 有了 Mist 和 Medis,你就拥有了和美团 Leaf、微信 Seqsvr、百度 UIDGenerator 性能相当(甚至超过)的全局唯一 ID 服务了。相比复杂的 UIDGenerator 双 Buffer 优化和 Leaf-Snowflake,薄雾算法 Mist 简单太多了。.

But suddenly i have this problem, help me to solve this :'(

Answered 2021-Jul-31 at 12:21The signature of your getAllServicesUserRequest
is incorrect. According to the provided json, it should receive ServiceResponse
, also when you enqueue the call you also defined there that you expect ServiceResponse
. So updating the signature of getAllServicesUserRequest
to Call
should fix your issue:

QUESTION
I want to create only one Asp.Net Core API Service for multiple website. they are almost same but have different content.
i want to know which website call API to return that website's contents.
for example :
Web Site One(angular client) : http://Game.medis.land
Web Site Two(angular client) : http://Tech.medis.land
API(/api/getservices) => return All Services (depend on which site call the API, method return different values)
if Site-One call =>{"previews","reviews"}
if Site-Two call =>{"software","hardware"}
how should i manage this? can i get URL from Header of request? or something else?
...ANSWER
Answered 2020-Oct-16 at 22:43There are many ways that you can handle it:
1- ClientType: every clients should introduce theirself for example Client B set a header key in all requests (ex: ClientType:client-b
) and you can determine your clients.
2- Origin: you can read the Origin
from request headers and determine clients by their domains but I think it's not good idea because may be domains changed any times.
3-Api key: you can generate a unique key for every clients( Guid
is a good choice) and clients should set their api key in all request header(ex api-key: XXXXXXXX
) and in server side determine the clients by key.
Finally I suggest you that handle clients in a middleware and pass it with http features to your controllers.

You aren't seeing any errors because you aren't printing any errors. It might make sense to print a list of errors if the form hasn't submitted. There are a variety of ways you can do that, such as printing errors on each field, or printing a list of errors at the top of the form:

QUESTION
Every little help is appreciated very much!
I got an Avatar as a Navigator, which should allow me to navigate through some screens! Some other Screens should be reached only by the my home screen. But when I press on the Button in the Avatar, nothing happens. I don't understand how and why, but I believe I made a mistake in the stackNavigator somewhere? Just to avoid any misunderstanding, the code below is shortened to avoid filling the page with unnecessary information, so it doesn't reflect 1:1 what you see in the screenshots.
Home Screen which should change
Avatar Screen through which I should be able to change the Home Screen
The goal is to be able to change which Screen is displayed in the through the
component below.
I tried with a onPress function inside the Avatar.js to call this.props.navigation.navigate("Agenda")
but the screen didn't change. At least I got rid of the errors thanks to passing the navigation prop. I believe I made kind of a scrub mistake since i'm not experienced with react native, I hope some of the more experienced users can help me with that :) furthermore I don't think the screen itself is important to solve this, it's just a class component with panresponder and animated view.
ANSWER
Answered 2020-May-22 at 18:44The problem is you are trying to access navigation outside the Appcontainer where the navigation is not available.
Easy fix : Moving the Avatar component inside one of your main screens(ScHome,ScNewMedi,ScCalendar) then you will have access to navigation and everything will work as expected.
Workaround : Let say the requirement is to have the Avatar outside the AppContainer then you have to use something like a navigation service.
The code would be as below
