UniApp implements the extension and usage of native components of Alipay mini program

UniApp is a cross-platform application development framework based on the Vue development framework. The code can be written at once and published to multiple platforms at the same time. The advantage of UniApp lies in its rich native component expansion capabilities, which can easily integrate third-party native components, such as the native components of the Alipay mini program. This article will introduce how to implement the expansion and use of Alipay applet native components in UniApp, and give code examples.

1. Extension of native components

The native components of the Alipay mini program refer to components that interact with the native API of the Alipay mini program through Javascript and can achieve some special effects and functions. To use the native components of the Alipay applet in UniApp, we need to first extend the capabilities of these components.

First, add the following code to UniApp’s pages.json configuration file:

"globalStyle": {
  "navigationBarTextStyle": "black",
  "navigationBarTitleText": "UniApp",
  "navigationBarBackgroundColor": "#ffffff",
  "app-plus": {
    "useAlipayOriginalNavigationStyle": true // 支付宝小程序使用原生导航栏
  },
  "usingComponents": {} // 在这里添加扩展的支付宝小程序组件
}

Then, create a uni_modules## in the root directory of the project # folder, and then create a @dcloudio/uni-alipay-plugin folder in it to store the component extensions of the Alipay applet. Create the unpackage folder in the @dcloudio/uni-alipay-plugin folder, and then create the plugin folder in it to store the extended Alipay plug-in Code for program components.

Next, create an

index.js file in the plugin folder, which is used to introduce the component extension code of the Alipay applet. The sample code is as follows:

import "@dcloudio/uni-alipay-plugin/xxxx"  // 以实际组件路径为准，如：button/index.js

Finally, create a

components.json file in the unpackage folder, which is used to describe the information of the extended Alipay applet component . The sample code is as follows:

{
  "xxxx": {
    "path": "@dcloudio/uni-alipay-plugin/xxxx",
    "style": {
      "path": "@dcloudio/uni-alipay-plugin/xxxx/style/index.css"
    }
  }
}

2. Use of native components

Now we can use the extended Alipay applet native components in UniApp.

First of all, we need to introduce the native components of the Alipay applet that need to be used in the vue component of a certain page. The sample code is as follows:

<template>
  <view>
    <button></button>  <!-- 使用扩展的支付宝小程序原生组件 -->
  </view>
</template>

<script>
  export default {
    components: {
      button: '@dcloudio/uni-alipay-plugin/xxxx'  // 以实际组件路径为准，如：button/index.vue
    }
  }
</script>

Then, we can use the extended Alipay applet native component in the vue component like a normal component.

3. Code example

The following is a sample code that uses the native components of the Alipay applet:

<template>
  <view>
    <button></button>
  </view>
</template>

<script>
  export default {
    components: {
      button: '@dcloudio/uni-alipay-plugin/button'
    }
  }
</script>

In this sample code, we introduce Alipay into the page The

button component of the applet is then used in the page.

The above is how to implement the extension and use of the native components of the Alipay mini program in UniApp. By extending the native components of the Alipay mini program, we can use more special effects and functions in UniApp. I believe that through the introduction and sample code of this article, you have mastered how to use the native components of the Alipay applet in UniApp. Hope this article is helpful to you!
