How does uniapp obtain push permission?

With the popularity of mobile applications, push services have gradually become an indispensable part of app development. Push services can provide users with timely message notifications and reminders, adding more functions and convenience to applications. Among them, obtaining push permission in uniapp is one of the skills that must be mastered during the development process.

In uniapp, you can obtain push permission through the following steps:

1. Add relevant configurations in the manifest.json file

First, in the uniapp project In the manifest.json file, you need to add the following configuration:

"manifest": {
    "app-plus": {
        "modules": {
            "push": {
                "provider": "yourProviderName"
            }
        }
    }
}

In this configuration, we added a submodule named "push" to the "app-plus" module of the application and specified the application The name of the program provider. This name can be anything you like, just make sure it's not repeated.

2. Create a push service provider

Next, we need to create a push service provider on the backend server of the application. It is recommended to use third-party push service providers, such as Huawei and Xiaomi, because the SDK they provide has encapsulated the push logic and can be easily integrated into the application. Of course, you can also use your own push service, but it requires more work.

3. Import push service provider SDK

After the push service provider has been created, we need to import its SDK into our uniapp project and call Related APIs to obtain push permissions. Take Huawei Push as an example:

(1) Add the configuration of Huawei Push Provider in the manifest.json file

"app-plus": {
    "modules": {
        "push": {
            "provider": "HuaweiPush",
            "multiProvider": true,
            "appId": "yourAppId",
            "apiKey": "yourApiKey",
            "secretKey": "yourSecretKey"
        }
    }
}

In this configuration, we use Huawei Push Service Provider, and Its appId, apiKey and secretKey are specified. These parameters can be found in the Huawei Developer Center.

(2) Import Huawei Push SDK in the main.js file

In the main.js file, we need to import Huawei Push SDK and initialize it:

import push from "@hadeeth/hms-push";
const APP_ID = "yourAppId";
push.initHuaweiPush({
    appId: APP_ID,
});

Among them, @hadeeth/hms-push is the Uni-app plug-in package corresponding to Huawei push SDK. We need to install it first. During the initialization process, we only need to pass in the appId.

(3) Obtain push permissions and related operations

When the application starts, we need to request the user to allow push services. You can use the following code to obtain push permission:

push.requestPermission().then(result => {
    console.log("permission result:" + result);
});

This will pop up a dialog box to the user asking whether to allow the push service. After the user agrees, we can register the device with the Huawei push service provider:

push.getToken(result => {
    console.log("token result:" + result);
}, err => {
    console.log("get token error:" + err);
});

In this way, we can obtain the push token of the device and use it to send push messages.

In addition to Huawei Push, other push service providers also have similar APIs and operating procedures, but the specific calling methods may be different. At the same time, we need to note that obtaining push permissions and related operations need to be called at the right time, otherwise it may cause some strange errors.

Summary

To obtain push permissions in uniapp, you need to complete the following steps: add relevant configurations to the manifest.json file, create a push service provider, import the push service provider's SDK, and obtain push Permissions and related operations. It should be noted that these operations need to be called at the right time, otherwise some errors may occur. By mastering these skills, we can easily implement push service functions in uniapp.
