VUE 實現element upload上傳圖片到阿里雲

首先安裝依賴

cnpm install ali-oss

封裝client

VUE 實現element upload上傳圖片到阿里雲

若是想減小打包後靜態資源大小,可在index.html引入:(然後在client.js裡註釋掉const OSS = require(‘ali-oss'))

<script src="http://gosspublic.alicdn.com/aliyun-oss-sdk-4.4.4.min.js"></script>


const OSS = require('ali-oss')

export function client(data) {
 // 後端提供資料
 return new OSS({
  region: data.endpoint,// *****.aliyuncs.com
  accessKeyId: data.accessKeyId,accessKeySecret: data.accessKeySecret,bucket: data.bucketName,endpoint: data.endpoint,secure: true
 })
}

然後,在vue頁面引用,給client傳入後臺返回的阿里資料

結果如下圖:

VUE 實現element upload上傳圖片到阿里雲

1、HTML部分

<el-upload
 action=""
 :http-request="Upload"
 :data="Aliyun"
 :multiple="false"
 :show-file-list="true"
 list-type="picture-card"
 :on-preview="handlePictureCardPreview"
 :on-remove="handleRemove"
 :limit="5"
>
 <i class="el-icon-plus" />
</el-upload>
<el-dialog :visible.sync="dialogVisible">
 <img width="100%" :src="dialogImageUrl" alt="VUE 實現element upload上傳圖片到阿里雲">
</el-dialog>
<p style="color: #999;">圖片上傳限制: 1.最多5張; 2.最大1M</p>

2、JS部分

import { getAliyun,createOrder } from '@/api/order-management'
import { client } from '@/utils/alioss'
export default {
 name: 'Appeal',data() {
  return {
   dialogImageUrl: '',dialogVisible: false,Aliyun: {},// 存簽名信息
   progress: 0,// 進度條
   imgUrl: [] // 存上傳後的圖片url
  }
 },created() {
  this.getAliyun()
 },methods: {
  // 獲取阿里雲資料
  async getAliyun() {
   const { data } = await getAliyun()
   this.Aliyun = data
  },// 上傳圖片
  Upload(file) {
   const that = this
   // 判斷副檔名
   const tmpcnt = file.file.name.lastIndexOf('.')
   const exname = file.file.name.substring(tmpcnt + 1)
   const names = ['jpg','jpeg','png']
   if (names.indexOf(exname) < 0) {
    this.$message.error('不支援的格式!')
    return
   }
   if (file.size > 1024 * 1024) {
    this.$message.error('圖片大小最大1M')
    return
   }
   async function multipartUpload() {
    // const fileName = that.name + file.file.uid
    const fileName = that.Aliyun.objectName + +'/' + Date.now() + '-' + file.file.name
    // fileName = aliyunConfig.objectName+'/'+Date.now()+'-'+file.name //所要上傳的檔名拼接 (test/)
    // 定義唯一的檔名,打印出來的uid其實就是時間戳
    // client 是第一步中的 client
    client(that.Aliyun).put(fileName,file.file,{
      progress: function(p) { // 獲取進度條的值
       console.log(p)
       that.progress = p * 100
      }
     }).then(
     result => {
      // 下面是如果對返回結果再進行處理,根據專案需要
      // console.log(result)
      // that.imgUrl = 'http://' + result.bucket + '.' + that.Aliyun.endpoint + '/' + result.name
      that.dialogImageUrl = result.url
      that.imgUrl.push({
       name: file.file.name,url: result.url
      })
      console.log(that.imgUrl)
     }).catch(err => {
     console.log('err:',err)
    })
   }
   multipartUpload()
  },// 圖片預覽
  handlePictureCardPreview(file) {
   this.dialogImageUrl = file.url
   this.dialogVisible = true
  },// 刪除圖片
  handleRemove(file,fileList) {
   // console.log(file)
   for (var i in this.imgUrl) {
    if (this.imgUrl[i].name === file.name) {
     this.imgUrl.splice(i,1)
    }
   }
  }
 }
}
</script>

補充知識:vue-cli專案中,配合element_ui來實現上傳圖片與視訊到oss上。

<template>
  <div class="basicInfo">
   <el-upload class="avatar-content"
    v-loading="fileLoading"
    accept="image/*"
    drag action="https://zxcity-app.oss-cn-hangzhou.aliyuncs.com"
    :show-file-list="false"
    :data="ossParams"
    :before-upload="checkParams"
    :on-progress="progress"
    :on-error="uploadErr"
    :on-success="uploadSuccess"
    :on-remove="fileListRemove"
    multiple
    >
   </el-upload>
   <div v-for="(item,index) in fileList" :key="index" class="imgDiv">
    <img :src="item.imgUrl" alt="VUE 實現element upload上傳圖片到阿里雲">
    <p>{{item.progress}}</p>
   </div>
  </div>
</template>
<script>
import axios from 'axios'
export default {

  return {
   form: {

   },fileList: [],fileLoading: false,ossParams: {

   }
  }
 },methods: {
  // 圖片上傳前檢測引數變化
  checkParams (file) {
   var _this = this
   var promise = new Promise((resolve,reject) => {
    axios.get('https://share.zxtest.izxcs.com/zxcity_restful/ws/oss/ossUpload',{})
     .then(function (response) {
      var params = response.data
      _this.ossParams = params
      _this.ossParams.name = file.name
      _this.ossParams.OSSAccessKeyId = params.accessid
      _this.ossParams.success_action_status = '200'
      _this.ossParams.key = params.dir + '/' + _this.getUUID()
      var obj = {
       name: _this.ossParams.name,key: _this.ossParams.key,host: _this.ossParams.host,progress: 0,imgUrl: ''
      }
      _this.fileList.push(obj)
      // _this.fileLoading = true
      resolve()
     })
     .catch(function (error) {
      console.log(error,'錯誤')
      reject(error)
     })
   })
   return promise
  },// 上傳中
  progress (event,file,fileList) {
   console.log('上傳中...')
   console.log(file)
   console.log(fileList)
   this.fileList.forEach((item,index) => {
    if (item.name === file.name) {
     item.progress = parseInt(file.percentage)
    }
   })
  },// 上傳失敗提示
  uploadErr (res) {
   this.$message.error('上傳出錯!')
  },// 上傳成功後上傳到file表
  uploadSuccess (response,fileList) {
   console.log('上傳成功')
   this.fileList.forEach((item,index) => {
    if (item.name === file.name) {
     item.imgUrl = item.host + '/' + item.key
     item.progress = 100
    }
   })
  },// 檔案刪除
  fileListRemove (file,fileList) {
   this.form.url = ''
  },// 隨機名稱
  getUUID () {
   return `${this.str4()}${this.str4()}-${this.str4()}-${this.str4()}-${this.str4()}-${this.str4()}${this.str4()}${this.str4()}`
  },str4 () {
   return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1)
  }
 }
}
