Response Headers的Content-Type值为image/jpeg，如何展示在前端页面
const blob = new Blob([response.data], { type: imageTypes[index] })
const blobUrl = window.URL.createObjectURL(blob)
// 响应拦截器
service.interceptors.response.use(
(response) => {
const contentType = response.headers['content-type']
const imageTypes = ['image/png', 'image/jpeg', 'image/jpg']
const index = imageTypes.indexOf(contentType)
if (contentType && index > -1) {
const blob = new Blob([response.data], { type: imageTypes[index] })
const blobUrl = window.URL.createObjectURL(blob)
// console.log('URL.createObjectURL(blob) to blobUrl', blobUrl)
return { data: blobUrl }
}
// ...
},
(error) => {
// ...
return Promise.reject(error)
}
)
