OpenAPI is an open API platform, what functions can it achieve

OpenAPI is an open API platform, and it mainly implements the following functions:

1) Dynamic consumption Management via Consumer

2) Dynamically manage API methods and their arguments

3) Dynamically generate API method usage instructions

4) Build lines Go to the Test environment

5) Online API call file wizard

6) Unified REST call path and API implementation strategy to facilitate writing API implementation logic What is QoS and how do I configure it ? What functions can it achieve?

The full name of QoS is "Quality of Service" in English and "Quality of Service" in Chinese. QoS is a security mechanism of the network and a technology used to solve problems such as network delay and congestion.

Under normal circumstances, if the network is only used for specific application systems without time restrictions, QoS is not required, such as Web applications, or E-mail settings, etc. But it is very necessary for critical applications and multimedia applications. When the network is overloaded or congested, QoS ensures that important traffic is not delayed or dropped, while ensuring efficient network performance. When configuring, you need to look at the network switch. Different brands of switches have different configurations, but one thing they have in common is that they must set priorities. What is an online advertising machine? What functions can it achieve?

The price of the online version of the advertising machine is higher than that of the stand-alone version, but the ads are updated quickly and can be controlled remotely, which saves labor. ◎The playback content can be changed anytime and anywhere (with background operating system) to implement unified publishing and scheduled release. ◎Supports the insertion function, which can promptly interrupt the latest news and emergency notifications. ◎Supports the playback of weather forecast, time/time, and PPT files. ◎Personalized layout: you can design your own page layout ◎Automatically set on/off ◎Full-screen split-screen carousel playback, support simultaneous playback of audio and video, multiple picture playback modes, and set the time for keeping pictures ◎Power-off memory. ◎ Full-featured remote control operation ◎ Equipped with anti-theft lock function to prevent the machine or storage device from being stolen. 496. What functions does the wifi module have? Can it be controlled by mobile APP?

The functions of wifi modules can realize different functions depending on the interface. For example, wifi modules with USB interface are generally used for wireless network cards; and wifi modules with SPI interface are generally used for Transmit slightly larger data; there is also the SDIO wifi module, which is generally used in mobile phone wifi modules; there is also a serial port wifi module, which is widely used and can allow some serial Networking of port devices is also a key application of the Internet of Things technology in the future; when we talk about mobile APP control, it is usually a serial port wifi module and an SPI wifi module. My friend has been working on these wifi things recently and saw him applying one. I am studying the STM32 microcontroller wifi development board: hx-wl../stm32-wifi/. They provide microcontroller source code and APP source code. It is a must-have tool for Internet of Things technology enthusiasts. I hope it will be helpful to you. I plan to buy a projector, and recently I paid attention to Xiaoshuai UFO. Can it realize 3D function?

Many projection devices can achieve this! The holographic projection in Nanjing Hann is pretty good! It has 3D function!

Answer: Thought is the slave of life, and life is the fool of time. What functions can be achieved with WPF?

Just think about it: Microsoft’s Visual Studio is all developed with WPF

The requirements you mentioned are trivial to him. What functions can lifecycle achieve

< p> Following the content of the previous article, this article analyzes the implementation principle of RxLifecycle while learning RxJava operators.

First, RxLifecycle defines BehaviorSubject in the base class and associates the life cycle of Activity or Fragment. When the life cycle is called, BehaviorSubject emits the data of the corresponding cycle. And BehaviorSubject also serves as an observer and is observed by custom operators at any time.

```java private final BehaviorSubject lifecycleSubject = BehaviorSubject.create(); @Override @CallSuper protected void onStart() { super.onStart(); lifecycleSubject.onNext(ActivityEvent.START); } @Override @CallSuper protected void onResume() { super.onResume(); lifecycleSubject.onNext(ActivityEvent.RESUME); } @Override @CallSuper protected void onPause() { lifecycleSubject.onNext(ActivityEvent.PAUSE); super.onPause(); } @Override @CallSuper protected void onS() { lifecycleSubject.onNext(ActivityEvent.STOP); super.onS(); } ``

Let’s take a look at how to provide defined transformers in the basic class, RxLifecycle The provided bindActivity method passes in BehaviorSubjec, and the defined operator is transformed according to the life cycle data. ```java @Override @NonNull @CheckResult public finalObservable.Transformer bindToLifecycle() { return RxLifecycle.bindActivity(lifecycleSubject); } ``` Paste the code of the core transformation operation, and analyze the ideas while getting familiar with some unfamiliar ones operator. Several key operational applications are implemented here to tie the changes in the life cycle. ###takeUntil TakeUntil subscribes to and starts reflecting the original Observable, and it also monitors the second Observable you provide.

If the second Observable emits an item or emits a termination notification, the Observable returned by TakeUtil will stop reflecting the original Observable and terminate. The source code uses this operation to determine whether to emit the original Observable. Program code to understand the role of takeUntil```Java Observable.just(1).takeUntil(Observable.create(new Observable.OnSubscribe() { @Override public void call(Subscriber subscriber) { subscriber.onNext("abc"); If "abc" is not emitted, the Log information is returned as onNext=1; } })).subscribe(Utils.getSubscriber()); `` ``java 04-26 18:19:59.886 15714-15714/qulei .rxjava.demo D/RxJava: onNext : 1 04-26 18:19:59.886 15714-15714/qulei.rxjava.demo D/RxJava: onCompleted ``` ###bineLatest When either of the two Observables is emitted When data is generated, a function is used to combine the most recent data item emitted by each Observable, and the data is emitted based on the result of this function. Here, based on changes in the BehaviorSubject life cycle, it is used to determine whether to emit data and terminate the original. It also monitors the second Observable you provide.

```java Observable.bineLatest( sharedLifecycle.take(1).map(correspondingEvents),sharedLifecycle.skip(1), new Func2() { @Override public Boolean call(R bindUntilEvent, R lifecycleEvent) { return lifecycleEvent.equals( bindUntilEvent); } }) ``` ###takeFirst ?If the original Observable does not emit any data that meets the conditions, takeFist will return an empty Observable (onNext() will not be called but onCompleted will be called). If the life cycle is not the tied cycle, it will continue to match the next cycle time. If it is the same, an empty Observable will be transmitted, and the original Observable will stop executing and emitting data. ?I hope this principle analysis can be helpful.
