我有图像数据数组，并尝试将其转换为文件数组

const images = [
  { img: "http://localhost/images/1.jpg", name: "1.png", mime_type: "image/jpeg" },
  { img: "http://localhost/images/2.jpg", name: "2.png", mime_type: "image/jpeg" },
]
const res: File[] = images.map(function (item) {
  return new File([item.img], item.name, { type: item.mime_type })
})

这不起作用:(据我了解，base24 中转换后的图像应该传递给文件构造函数？我该怎么做？

更新： 我有一个 VUE 组件来处理图像。输入组件具有数组类型的属性。如何根据数据库返回的数据创建数组。从数据库返回：图像链接、名称和类型。

UPD2答案：

let PhotosAsFile: File[] = []
const _photos = [
  { url: "http://localhost:8080/images/1.jpeg", name: "name1", mime_type: "image/jpeg" },
  { url: "http://localhost:8080/images/2.jpeg", name: "name2", mime_type: "image/jpeg" },
  { url: "http://localhost:8080/images/3.jpeg", name: "name3", mime_type: "image/jpeg" },
]

const data: Promise<File>[] = _photos.map(async function (item): Promise<File> {
  const myBlob: Blob = await getBlobFromUrl(item.url)
  const extensionsFile: RegExpMatchArray | null | undefined = item.url?.match(/\.([^.]+)$/)

  return new File([myBlob], extensionsFile && item.name ? item.name + "." + extensionsFile[1] : "image.jpeg", {
    type: item.mime_type ?? "image/jpeg",
  })
})

Promise.all(data).then((values: File[]): void => {
  PhotosAsFile = values
})

const getBlobFromUrl = (url): Promise<Blob> => {
  return new Promise((resolve, reject): void => {
    const request: XMLHttpRequest = new XMLHttpRequest()
    request.open("GET", url, true)
    request.responseType = "blob"
    request.onload = () => {
      resolve(request.response)
    }
    request.onerror = reject
    request.send()
  })
}
