OpenAPI is an open API platform. What function can it achieve?

OpenAPI is an OpenAPI platform. What functions can it achieve? OpenAPI is an open API platform, which mainly realizes the following functions:

1) dynamically manage consumers.

2) Dynamically manage API methods and their parameters.

3) Dynamically generate API method instructions.

4) Build an online test environment.

5) Online API calls file wizard.

6) Unified REST call path and API implementation strategy, which is convenient for writing API implementation logic.

What is QoS and how do I configure it? What function can it achieve? QoS is called "quality of service" in English and "quality of service" in Chinese. QoS is a security mechanism of the network and a technology to solve the problems of network delay and congestion.

? Under normal circumstances, if the network is only used for a specific application system and there is no time limit, it does not need QoS, such as Web applications or email settings. But it is necessary for critical applications and multimedia applications. When the network is overloaded or congested, QoS can ensure that important traffic is not delayed or discarded, and at the same time ensure the efficient implementation of the network. Configuration depends on what network switches, different brands of switches, different configurations, but have one thing in common, that is, priority must be set.

What are the functions of the wifi module, and can it control the mobile APP? The function of wifi module can realize different functions according to different interfaces. For example, wireless network cards generally use wifi modules with USB interfaces. There is also a wifi module with SPI interface, which is generally used to transmit slightly larger data; There is also a SDIOwifi module, which is generally used for mobile phone wifi modules; There is also a serial wifi module, which is widely used and can connect some serial devices, and it is also the key application of Internet of Things technology in the future. When we talk about mobile APP control, it is generally a serial wifi module and a SPIwifi module. My friend has been studying these wifi things recently. He saw that he was learning with a STM32 microcontroller wifi development board: HX-WL.../STM 32-WiFi/ They provided the source code of the microcontroller and the source code of the APP, which is a necessary weapon for Internet of Things technology enthusiasts. I hope it helps you.

I am going to buy a projector, and I have recently paid attention to the handsome UFO. Can you realize 3D function? Many projection devices can be realized! The holographic projection of Nanjing Hann is good! With 3D function!

Ucenter api which interface can realize the registration function? Use special objects provided by MySql Connector/

MySqlDataReader myreader = mycmd。 ExecuteReader()；

And (myreader. Read())

What function can VPDN achieve? Answer: Thought is the slave of life, and life is the trick of time.

What function can WPF achieve? Microsoft's Visual Studio is all developed by WPF. Think about it.

These needs you mentioned are nothing to him.

What function can a life cycle achieve? Following the last article, this paper analyzes the implementation principle of RxLifecycle and learns RxJava operators.

First, RxLifecycle defines the behavior subject in the basic class and binds the life cycle of the activity or fragment. When the life cycle is called, the behavior subject passes the data of the corresponding cycle. As the observed person, BehaviorSubject is observed by the user-defined operator at any time.

` ` Java private final behavior subject life cycle subject = behavior subject . create()； @ Override @ call super protected void onStart(){ super . onStart()； life cycle subject . on next(activity event。 Start); } @ Override @ call super protected void on resume(){ super . on resume()； life cycle subject . on next(activity event。 Resume); } @ Override @ call super protected void on pause(){ life cycle subject . on next(activity event。 Pause); super . on pause()； } @ Override @ call super protected void onS(){ life cycle subject . on next(activity event。 Stop); super . ons()； } ```

Let's see how to provide defined conversion operators in the base class. The bindActivity method provided by RxLifecycle is passed into BehaviorSubjec, and the defined operators are converted according to the life cycle data. ` ` Java @ Override @ NonNull @ check result public final observable。 transformer bindToLifecycle(){ return rx life cycle . bind activity(life cycle subject)； Paste the code of core transformation operation, and be familiar with several unfamiliar operators while analyzing ideas. Several key operational applications are implemented here, and the change of binding life cycle is realized. # # # Takeuntill Takeuntill subscribes and starts to reflect the original observable value, and it also monitors the second observable value provided by you.

If the second observable sends data or termination notice, the observable returned by TakeUtil will stop reflecting the original observable and terminate. The source code uses this operation to determine whether to transmit the original observable. Understand the code of takeUntil ``` Java Observable function. Just (1). Takeuntil (observable. Create (a new observable object. On subscribe () {@ override public void call (subscriber) {subscriber. on Next(" ABC "))； If "abc" is not sent, the log information will be received back to on next =1; } })).subscribe(utils . get subscriber())； ` ```` Java 04-26 18: 19:59.886 14- 157 14/qu lei . rx Java . demo D/rx Java:on next: 1 04-26 1 8: 19:59.886 654338 Here, according to the change of the life cycle of BehaviorSubject, it is judged whether to transmit data, and at the same time, the second observable provided by you is monitored. ` ` Java observable . bine latest(shared life cycle . take( 1)。 map(correspondingEvents)，sharedLifecycle.skip( 1)，new func 2(){ @ Override public Boolean call(R bindutilevent，R lifecycleEvent){ return lifecycleEvent . equals(bindutilevent)； } }) ``` ###takeFirst？ If the original observable object does not transmit any qualified data, takeFist will return an empty observable object (instead of calling onNext (), call onCompleted). If the life cycle is not a binding cycle, it will continue to match the time of the next cycle. If they are the same, it will send an empty observable object and stop the original observable object from transmitting data. ? The principle analysis here hopes to bring help.
