How to realize taking pictures and photo editing in uni-app

1. Introduction

With the popularity of mobile devices, taking pictures and photo editing functions increasingly common in a variety of applications. This article will introduce how to use uni-app to implement photo taking and photo editing functions, and provide relevant code examples. I hope it can provide some reference for developers to implement these functions in uni-app.

2. Implement the camera function

The camera function can be implemented through the native API of uni-app. The following is a simple code example of the camera function:

<template>
  <view>
    <button @click="takePhoto">拍照</button>
  </view>
</template>

<script>
export default {
  methods: {
    takePhoto() {
      uni.chooseImage({
        count: 1,
        success: (res) => {
          const tempFilePaths = res.tempFilePaths
          // 将照片路径存储到本地或上传到服务器
        },
      })
    },
  },
}
</script>

In the above code, we trigger the camera function through the uni.chooseImage() function, and obtain the temporary file path of the photo in the success callback function .

3. Realize the photo editing function

The photo editing function can be realized through the uni-app plug-in. There are many useful photo editing plug-ins on the market, such as the u-cropper plug-in in uView-ui. The following is a code example for a simple photo editing function:

First, add "uView": "uview-ui"## to pages.json in the project root directory #rely.

Then, introduce the u-cropper plug-in into the page where you need to use the photo editing function:

<template>
  <view>
    <button @click="editPhoto">编辑照片</button>
    <u-cropper ref="cropper"></u-cropper>
  </view>
</template>

<script>
import { uCropper } from '@/uview-ui'

export default {
  components: {
    uCropper,
  },
  methods: {
    editPhoto() {
      uni.chooseImage({
        count: 1,
        success: (res) => {
          const tempFilePaths = res.tempFilePaths[0]
          this.$refs.cropper.show(tempFilePaths)
        },
      })
    },
  },
}
</script>

In the above code, we pass ## in the

editPhoto method #uni.chooseImage()The function selects a photo and passes its path to the show method of the u-cropper plug-in for editing. 4. Summary

Through the native API and plug-ins of uni-app, we can easily realize the taking and photo editing functions. This article gives a simple sample code, but in actual development, further customized development can be carried out according to your own needs and project characteristics. I hope this article has provided some help for you to implement photo taking and photo editing functions in uni-app.
