因为浏览器和微信浏览器区别，导致直接使用capture=”camera”，浏览器会调用相机。解决方案，就是在组件加载时候，判断一下内核
代码如下
<template> <p id="info-container"> <ul class="nav-wrapper"> <li class="head-item"> <p class="item-wrapper"> <p class="left-item">头像</p> <p class="right-item"> <img :src="login.avatar_url?login.avatar_url: ''" class="head" :onerror="errImage" > <img class="point" src="../../assets/images/mine/point.png"> </p> </p> <!-- 这是需要样式控制input，让其定位到父集元素顶层，透明度为0 --> <input type="file" accept="image/*" ref="uploadFile" @change="changeFileHandler" capture="camera" v-if="iswx" /> <input type="file" accept="image/*" ref="uploadFile" @change="changeFileHandler" v-if="!iswx" /> </li> </ul> </p></template><script>import { USER_DEFAULT_BASE64, HEAD_IMAGE_SIZE_TO_BIG} from '../../utils/Constants'import { mapGetters, mapActions } from 'vuex'export default { name: 'info-container', computed: { ...mapGetters([ 'getAuthLogin' ]), login () { return this.$store.getters.getAuthLogin } }, created () { const agent = navigator.userAgent.toLowerCase() this.iswx = agent.indexOf('qqbrowser') >= 0 }, methods: { ...mapActions([ 'authUpdateAvatarUrl' ]), showTextHandler (text = '') { this.$vux.toast.text(text) }, changeFileHandler (e) { const files = e.target.files const uploadFile = this.$refs.uploadFile const localFile = files[0] const fileSize = localFile.size / 1024 const fileName = localFile.name if (fileSize > 1024 * 3) { this.showTextHandler(HEAD_IMAGE_SIZE_TO_BIG) } else { // 表单文件上传 this.authUpdateAvatarUrl({fileName, localFile}) } // 延迟一段事件清除内容 setTimeout(() => { uploadFile.value = '' }, 200) } }, data () { return { iswx: false, errImage: USER_DEFAULT_BASE64 } }}</script><style scoped lang="less"> //TODO 样式</style>
