一、思路，从后台获取七牛token，上传图片到七牛，获取返回图片路径放入el-upload。

二、代码。

<el-input v-model="listVideoQuery.orgLogo" @change="orgLogoChange"></el-input>
  <el-col :span="10" class="mt10">
  <el-upload class="upload-demo" :file-list="fileList2" :action="domain" :before-upload="beforeAvatarUpload" :data="form"
  :on-remove="handleRemoveQrgLogo" :on-success="handleAvatarSuccess" list-type="picture" :limit="1" multiple>
  <el-button size="small" type="primary" @click="upPicName='orgLogo'">点击上传</el-button>
  <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
  </el-upload>
  </el-col>

export default {
 name: 'edit',
 data() {
 return {
 upPicName:'', //上传图片名字
 fileList1:[],
 form: {}, //上传到七牛的token 
 bucketQuery:{
  bucket: 'website-image' //这是我用来获取token传给后台的字段
 },
 domain: 'http://upload.qiniu.com', // 七牛云的上传地址
 qiniuaddr: 'pd6rnk9ck.bkt.clouddn.com' // 这是七牛云空间的外链默认域名
 }
 },
 methods: {
 // 上传图片规格
 beforeAvatarUpload (file) {
 const isJPG = file.type === 'image/jpeg' || file.type === 'image/png'
 const isLt2M = file.size / 1024 / 1024 < 5
 if (!isJPG) {
  return this.$message.error('上传文件只能是 JPG或PNG 格式!')
 }
 if (!isLt2M) {
  return this.$message.error('上传图片大小不能超过 5MB!')
 }
 return upQiniu(this.bucketQuery).then(res => {
  this.form = {
  token:res.data
  }
 })
 },
 //图片改变及上传
 bannerPicChange(value) {
 this.fileList1 = []
 this.fileList1.push({
  name: value, 
  url: value
 }) 
 },
 handleBannerPicRemove(file, fileList) {
 this.fileList1 = []
 this.listVideoQuery.orgLogo= ''
 },
 handleAvatarSuccess(response) {
 if(this.upPicName =='orgLogo'){
  this.fileList1 = []
  this.fileList1.push({
  name: 'http://' + this.qiniuaddr + '/' + response.key, 
  url: 'http://' + this.qiniuaddr + '/' + response.key
  }) 
  this.listVideoQuery.orgLogo= 'http://' + this.qiniuaddr + '/' + response.key
 }
 this.$message({
  type: 'success',
  message: '上传成功!',
  duration: 2000
 }) 
 },
 }
 }

三、效果。
