2023年微信小程序API 背景音频·监听暂停事件

1. The Importance of Audio in Mini-Programs

WeChat mini-programs offer a range of features to help businesses engage with customers. One such feature is background audio, which allows music or other sound effects to be played in the background while the app is running.

This is particularly useful for businesses that are looking to create an immersive experience for their customers. For example, a restaurant could use background audio to play ambient sounds such as sizzling pans and clinking glasses, creating a more realistic environment for customers who are browsing the menu.

However, in order to use background audio effectively, it is important to be able to listen for pause events. This will allow the app to respond appropriately when the user pauses the audio or when it is interrupted for some other reason.

2. Understanding the wx.onBackgroundAudioPause Event

The wx.onBackgroundAudioPause() function is used to listen for music pause events. When a pause event occurs, the specified callback function is called.

2.1 Parameters

The only parameter of the wx.onBackgroundAudioPause() function is the callback function. This function will be called when the pause event occurs.

3. Migrating from wx.onBackgroundAudioPause to wx.getBackgroundAudioManager

It is worth noting that the wx.onBackgroundAudioPause() function has been deprecated since version 1.2.0 of the WeChat mini-program API. Developers are now encouraged to use the wx.getBackgroundAudioManager function instead.

The wx.getBackgroundAudioManager function provides a more comprehensive set of controls for managing background audio, including the ability to play, pause, and seek within audio tracks. It also allows developers to query the current playback status, duration, and other metadata about the audio being played.

If you are planning to develop a new WeChat mini-program or update an existing one, we recommend using the wx.getBackgroundAudioManager function instead of wx.onBackgroundAudioPause(). This will ensure your app is using the latest technologies and is less likely to encounter compatibility issues in the future.

4. Conclusion

In summary, background audio is a powerful tool for enhancing the user experience of WeChat mini-programs. However, it is important to be able to listen for pause events in order to provide a seamless and responsive experience for users.

The wx.onBackgroundAudioPause() function is one way to achieve this, but developers should be aware that it has been deprecated in favor of the more feature-rich wx.getBackgroundAudioManager function.
