我网上搜了一下，说window.URL.createObjectURL(res)可以但是没有效果fetchData() {

const id = this.$route.query.companyId

getCusInfo(id).then(res => {

const _data = res.data

this.detail = _data

getFileDetail(_data.adAvatar).then(res => {

// const blob = new Blob([res.data], { type: 'image/png' })

// const url = window.URL.createObjectURL(blob)

// this.brandLogoUrl = url

const src = window.URL.createObjectURL(res)

this.brandLogoUrl = src

console.log('res', res)

})

console.log('brandLogoUrl', this.brandLogoUrl)

})

},

class="avatar-uploader"

action="#"

:http-request="advertiserUpload2"

:show-file-list="false"

>

我暂时是这么处理的
