uniapp cannot receive offline push

With the rapid development of mobile Internet, mobile applications have become an indispensable part of our lives. As APPs become more and more widely used, the push function becomes more and more important. Offline push is a type of push function that can send notification messages to users when the APP is in the background or closed. However, in the process of using uniapp to develop applications, you may encounter the problem of not receiving offline push.

1. What is uniapp

uni-app is a cross-platform development framework based on Vue.js, which allows developers to use a set of codes to run on iOS, Android, H5, Xiaomi programs on multiple platforms. The emergence of the uni-app development framework allows developers to quickly develop high-performance, cross-platform applications, thereby greatly improving development efficiency.

2. Implementation of offline push in uniapp

In uniapp, the implementation of offline push can be completed by calling the API of the third-party push platform. uniapp can call the APIs of multiple push platforms such as Huawei, Xiaomi, Jiguang, and Baidu to build its own push service. In order to achieve offline push, we need to register the application on the platform and obtain the corresponding APPID, APPKEY and other necessary parameters. In the process of integrating the push platform SDK, you need to follow the relevant documents of the platform for development.

3. Reasons why offline push messages cannot be received in uniapp

In uniapp development, we may encounter situations where offline push messages cannot be received. This may be caused by the following reasons ：

1. The push service is not opened correctly

During the development process, we need to confirm whether the push service is opened correctly. We need to check how to open the push service in the document, and configure and start it according to the requirements in the document.

2. Push configuration error

During the process of configuring the push service, we may set the wrong login account, APPID or APPKEY. If these parameters are configured incorrectly, the push service will not be used correctly. Therefore, we need to pay attention to careful inspection when configuring parameters.

3. The application is closed

If our application has been closed, the push service cannot be used normally. In this case, we need to restart the application and confirm whether the push service can send offline push messages normally.

4. How to solve the problem of not receiving offline push messages

When encountering the problem of not receiving offline push messages, we can try the following solutions:

1 .Check the push service configuration

We can check the push service configuration to ensure that the login account, APPID, APPKEY and other parameters are set correctly, and the push service has been started correctly.

2. Check whether the application code is correct

Check whether the application code is correct. We must pay special attention to whether the code correctly calls the push service API. If the necessary API calls are missing, the push service will not work properly.

3. Check whether the platform push service is normal

We can check the platform push service status and check whether the platform service is working properly. If there is a problem with the platform service, we need to promptly notify the platform administrator to handle it.

4. Check whether the device is normal

If there is a problem with our device, the push service will not work properly. We can check the network connection status of the device and ensure whether the device has enough storage space and other conditions.

5. Summary

Offline push is an important function of mobile applications, and there is also a set of simple and easy-to-use API calls in uniapp. When we encounter the problem of not receiving offline push messages, we can investigate from many aspects such as service configuration, code implementation, platform push services and equipment, etc. to find the problem and solve it. Once we successfully solve this problem, we can make the application have a better user experience and increase the value of the application.
