How to use the sharing function in uniapp

In mobile application development, the sharing function is one of the most common and important functions. uniapp is a front-end development framework based on Vue.js, which can enable a set of codes to run on multiple platforms at the same time, including iOS, Android and Web. In uniapp, we can implement the sharing function through some simple codes. This article will introduce in detail how to use the sharing function in uniapp.

1. Install the plug-in

First, we need to install the sharing plug-in officially provided by uniapp. Open the uniapp project, click on the plug-in market, search and select the "uni-share" plug-in, and click to install. After the installation is complete, introduce the plug-in into the project.

2. Configure sharing information

Before sharing, we need to configure the relevant information to share, including title, description, pictures, etc. In the root directory of the uniapp project, find the pages.json file and add the "share" field in it:

"share": {
  "title": "这是分享的标题",
  "imageUrl": "/static/logo.png",
  "path": "/pages/index/index"
}

Among them, title is the shared title, imageUrl is the image path displayed when sharing, and path is the shared Page path. Replace the specific value with your own sharing information.

3. Display the share button

In the page where the share button needs to be displayed, you can add a bb9345e55eb71822850ff156dfde57c8 button element under the d477f9ce7bf77f53fbcf36bec1b69b7a tag and set a click event. Trigger sharing function.

<button @click="share">分享</button>

4. Write a sharing method

Next, in the 3f1c4e4b6b16bbbd69b2ee476dc4f83a tag of the page, write a method named share. This method will be triggered when the share button is clicked.

methods: {
  share() {
    uni.share({
      provider: 'weixin',
      type: 0,
      title: this.$root.$mp.page.data.share.title,
      imageUrl: this.$root.$mp.page.data.share.imageUrl,
      path: this.$root.$mp.page.data.share.path,
      success: () => {
        uni.showToast({
          title: '分享成功',
          icon: 'none'
        });
      },
      fail: () => {
        uni.showToast({
          title: '分享失败',
          icon: 'none'
        });
      }
    });
  }
},

In the sharing method, we call the uni.share method of uniapp to perform the sharing operation. By setting the provider field to "weixin", it indicates that WeChat is selected as the sharing platform. The type field is used to set the sharing type, 0 means sharing to the conversation, 1 means sharing to the circle of friends. The title, imageUrl, and path fields respectively correspond to the previously configured sharing information. The success and failure callback functions are defined in success and fail respectively, and corresponding prompt information is provided when the sharing is successful or failed.

5. Run the test

After the configuration is completed, you can run the uniapp project. Click the share button on the page. The sharing panel should pop up normally, select the platform and perform the sharing operation. After the sharing is successful or failed, the corresponding prompt message will pop up.

Summary

Through the above steps, we can easily implement the sharing function in uniapp. With the cross-platform feature of uniapp, we only need to write code once and can use it on multiple platforms at the same time and enjoy the convenience and user experience brought by the sharing function, adding more social features to mobile applications.
