How to implement electronic photo albums and photo sharing in uniapp
Title: Tutorial on realizing electronic photo albums and photo sharing using Uniapp
In modern society, photo albums and photo sharing have become an indispensable part of people's lives. Using the Uniapp development framework, we can easily implement electronic photo albums and photo sharing functions. This article will introduce how to use Uniapp to develop a simple but powerful electronic photo album and photo sharing application, and provide specific code examples.
-
Create Uniapp project
First, you need to install the uni-app development tool, which can be downloaded from the official website. After the installation is complete, you can create a Uniapp project in the command line through the following command:vue create -p dcloudio/uni-preset-vue 项目名称
- Project structure
After the project is successfully created, some files and folder. We will focus on the following folders:
- pages: The folder that stores page files
- components: The folder that stores component files
- static: Folder to store static resource files
- Create pages and components
Create two page files under the pages folder: Album.vue and PhotoShare.vue. Album.vue is used to display photo albums, and PhotoShare.vue is used to share photos. We also need to create a component Photo.vue to display the detailed information of each photo.

Album.vue code example:
<template> <view> <view v-for="(album, index) in albums" :key="index"> <image :src="album.coverUrl"></image> <text>{{ album.name }}</text> </view> </view> </template> <script> export default { data() { return { albums: [ { name: '相册1', coverUrl: 'static/album1_cover.jpg' }, { name: '相册2', coverUrl: 'static/album2_cover.jpg' }, { name: '相册3', coverUrl: 'static/album3_cover.jpg' }, ], }; }, }; </script>
-
PhotoShare.vue code example:
<template> <view> <button @click="sharePhoto">分享照片</button> <image v-for="(photo, index) in photos" :src="photo.url" :key="index"></image> </view> </template> <script> export default { data() { return { photos: [], }; }, methods: { sharePhoto() { // 调用系统相机拍摄照片 uni.chooseImage({ success: (res) => { this.photos.push({ url: res.tempFilePaths[0] }); }, }); }, }, }; </script>
-
Photo.vue code example:
<template> <view> <image :src="photo.url"></image> <text>{{ photo.name }}</text> </view> </template> <script> export default { props: { photo: Object, }, }; </script>
-
Page navigation
Set page navigation in the App.vue file and set Album.vue as the homepage , set PhotoShare.vue as the photo sharing page. Configure the page path and title in the pages.json file:{ "pages": [ { "path": "pages/album/Album", "style": { "navigationBarTitleText": "电子相册" } }, { "path": "pages/photoShare/PhotoShare", "style": { "navigationBarTitleText": "照片共享" } } ] }
-
Test application
Now you can deploy the code to a real machine for testing. Execute the following command in the command line to compile the code to the real device:npm run dev:mp-weixin
Then import it into the WeChat developer tool for real device preview.
The above are the basic steps to use the Uniapp framework to realize electronic photo albums and photo sharing. You can expand and optimize these codes according to actual needs to achieve richer functions and interactive experiences.
