适用于img和video
function requestImage(fileUrl, element,token) {
const xhr = new XMLHttpRequest()
const url = fileUrl
xhr.open('get', url, true)
xhr.setRequestHeader('Authorization', `Bearer ${token}`)
xhr.responseType = 'blob'
xhr.onreadystatechange = e => {
if (xhr.readyState === XMLHttpRequest.DONE && xhr.status === 200) {
element.src = URL.createObjectURL(xhr.response)
element.onload = () => {
URL.revokeObjectURL(element.src)
}
}
}
xhr.send(null)
}
