Overview
Uni-push is an integrated and unified dcloud joint push companyDelivery services, is the preferred delivery service for all un-app developers. Before we introduce the uni-push, let's find out what a push is。
What's push
Push (pushing services) refers to the technology by which the server sends messages to clients on its own initiative. Immediate data are available without the client's continuous query server。
The client has many disadvantages:
Client applications must be on-line in real time; cell phones are severely power-consuming; servers are loaded and wasteful。
Cellular notice boards, subscriptions to small programs are a push that provides a push channel at the bottom of the cell phone operating system or micro-intelligence to shield the various faults of the inquiry. Your application can be shut down, so as long as your mobile phone is online, the push channel provided by the operating system is online in real time。
Reminder: the web browser's webnotification is in fact a local notice bar, and the browser does not provide a push channel。
When the client is online, push is achieved by the socket protocol. When the client is offline, the server does not find the client, the developer is unable to carry it on its own. It can only send the message by relying on the mobile phone operating system, offline messages from the bottom of the applet, and calling the server interface of the specified mobile phone manufacturer or small programmer。
So a push system requires three parts of collaboration: developer's business server + professional push server + developer's client application。
Its main processes are:
The developer's business server sends instructions to professional push servers about what kind of messages need to be sent to clients the professional push server then sends messages to clients if the mobile phone is applied online and received push directly; if it is not online, the mobile phone user sees push messages in the operating system's notice box, clicks and calls the client's application, the client's code receives the response message; if it is a small application, the subscriber is read in the micromail, click on the applet and get the starter parameters。
Product introduction
Uni-push is an integrated integrated delivery service launched by a joint dcloud company, which has a third-party system-level push and push for mobile phone manufacturers such as apple, huacheng, mi, oppo, vivo, iwa, google fcm。
The country’s android push is a chaotic world, because google’s push service fcm is walled up, so some android mobile phone manufacturers in the country have made their own pushes, such as huacheng, mi, oppo, vivo, imam, etc., but many national mobile phone manufacturers have not provided official push programmes. By push, the tri-partite independent company provided an independent push programme. Before the absence of uni-push, the use of a three-way push would make it impossible to keep the push process alive on many national mobile phones because of the power-saving set-up. And if the official push sdk of every android cell phone were to be developed together, there would be a huge workload and management maintenance。
Uni-push solves this problem, and developers need only develop once. The system automatically selects the most reliable delivery channel on different mobile phones to send push messages and secure service。
Un-push, which reduces the cost of development, increases the rate of push service and is free of charge, is the best solution currently delivered。
Apply scene
The following functions can be performed with uni-push
Noun interpretation noun explanation
Organisation
When you specify the title and content of a notice, you have to push the sdk to automatically display the message of the notice bar in the system notification bar and at the same time ring the bell or vibrate the alarm user (bell and vibrating is affected by the configuration of the mobile phone system)。
Passing through
This means that a custom message can be defined by a client in a message format, such as a pure text, a json string, etc. Passage only conveys data without any processing, and the client needs to follow-up action, such as displays in the notice box, bullet frames, etc., after receiving the fax。
Clientid
The external user identifier in a push business layer, used to identify the client, which was retrieved by a third-party client and kept at a third-party service end, is the only identification number for the push sdk, short cid。
Online delivery
App sends the message through a push channel when you open the front desk。
Offline
App sends messages through the manufacturer's channels when backstage, lock screen, process closes. The type cannot be driven offline without integrated android multi-manufactor, unconfigured ios certificate。

Message delivery process
Product version
Un-push currently has two versions, un-push 1. 0 and un-push 2. 0. Uni-push 2. 0 is an all-end (app, applet, web) integrated cloud delivery service introduced by dcloud, and recommends that developers prioritize uni-push 2. 0。
Watch out for the logic of the transport route
Chinese mobile phones must be installed in order to be able to use the china mobile service (wam) portal, ensuring first that the wwam mobile service application is installed on the mobile phone. If the message cannot be received after the exit from china for mobile phone applications, ensure that:
The machine version requires: chinese rom version greater than or equal to emui4. 1 and chinese version greater than or equal to 2. 5. 2 for mobile services (available in the application list or in the application market). A cloud pack is required and a certificate-signature package is required (the name of the package is to be identified as consistent with the chinese platform). "sha256 certificate fingerprints" are filled in for the platform "my project" -- "project settings" -- "general" -- cross-referenced to the right to save the certificate fingerprints. Emui10's mobile phone, check the cell phone notification access set, open the access to the [market notifications] as well, without defaulting on silence, which is to be seen by pulling down the notice bar. If the message from the mobile phone notification bar is fully stored, clear the message from the already stored message box to see if the new information can be displayed. Clear the cache of chinese mobile services (hms core) (apk (cell phone settings -- application -- application management -- click to display system processes -- search -- storage -- clean cache)
After hbuilderx 3. 0. 7, china needs a new configuration-services. Json file in addition to the original vendor information。
Vivo vendor channel
It is necessary to go online at the vvo app store to apply for attention from the vivo manufacturer:
Oppo vendor channel
We need oppo app store to go online to apply for oppo company delivery
And there are the following requirements:
The miller trail, the himalayas, the google fcm channel
The android mobile phone is already installed and the mobile phone network has access to google fcm delivery servers. For a detailed curriculum see also: how to use fcm。

Other relevant resources
With uni-push, developers should no longer use other push programmes. But we find that many developers have misperceptions that lead to the misuse of other pushes。
"uni-push is a pain in the ass. I like the simple sdk of push, aurora, and i don't want to go to the rom factory and apply for a lap."
Uni-push is not based on applying for permission from a mobile phone manufacturer, and if you do not apply for those, they are used in the same way as normal push. However, it is particularly important to note that the current situation in the export industry is that it is not possible to send push when the app is offline without the promotion of integrated rom manufacturers. Using the usual push model, the consequence is that no offline messages can be sent on chinese, mi, oppo, vivo, or the himalayan。
“uni-push service rate high? Whether or not to pay for the increase in the rate of service, plus the method of payment for the increase.”
It has already been explained that the product of a push-up fee to increase the rate of delivery is vip push, while the uni-push is vip push. Dcloud negotiated for free to dcloud developers。
Can a uni-push replace socket in its entirety
Could be partially replaced. The communication protocol for the un-push client to receive messages belongs to websocket; however, the business service sent messages to the un-push service using the http communication protocol with a delay of 1-2 seconds. An application with a very low delay is required, such as an inappropriate multi-person interactive remote drawing board. But there's no problem with ordinary im news, chatting, notification。
5+app and wap2app support un-push
Hbuilderx 2. 0. 3, 5+app and wap2app can use uni-push 1. 0 without supporting uni-push 2. 0. 5+app and wap2app upgradesuni-push do not require changes to the app front-end code, but simply open the module configuration page in hbuilderx, tick the "unipush" under "push" and click on "configuration", open the uni-push service in the backstage and configure the vendor to re-submit parameters to clouds. The back-end server needs a second step of reference for the push-over service。
How does the un-app x project use un-push
Un-app x only supports uni-push 2. 0, developing documentation references: https://doc. Dcloud. Net. Cn/uni-app-x/api/uni-push. HTML
