要在uni小程序中生成当前页面的二维码,可以使用uni-app官方提供的uni-qrcode组件。首先,在需要展示二维码的页面引入该组件:
```vue
<template>
<view>
<uni-qrcode :text="qrcodeText"></uni-qrcode>
</view>
</template>
<script>
export default {
data() {
return {
qrcodeText: 'https://www.example.com' // 这里填入需要生成二维码的链接或文本
}
}
}
</script>
```
这样就可以在页面上展示二维码了。如果需要将当前页面的链接作为二维码内容,可以使用uni.getSystemInfoSync()获取当前页面的链接,然后将其赋值给qrcodeText即可:
```vue
<template>
<view>
<uni-qrcode :text="qrcodeText"></uni-qrcode>
</view>
</template>
<script>
export default {
data() {
return {
qrcodeText: ''
}
},
onLoad() {
// 获取当前页面链接
const pages = getCurrentPages()
const currentPage = pages[pages.length-1]
const url = `/${currentPage.route}`
const query = Object.keys(currentPage.options).map(key => `${key}=${currentPage.options[key]}`).join('&')
const fullUrl = `${url}?${query}`
// 将链接作为二维码内容
this.qrcodeText = fullUrl
}
}
</script>
```
注意,uni-qrcode组件需要在manifest.json文件中声明使用,例如:
```json
{
"mp-weixin": {
"usingComponents": {
"uni-qrcode": "@dcloudio/uni-ui/lib/uni-qrcode/uni-qrcode"
}
}
}
```
以上代码仅适用于微信小程序平台,其他平台可能会略有不同。
