简单地模拟 `Upload.Img` 所支持的 Props

```jsx
const link = "http://wxa.wxs.qq.com/images/preview/img-placeholder_320x180.png"

const [progress, setProgress] = useState(null)
const [src, setSrc] = useState(link)
const upload = useRef(null)

useEffect(() => {
  if (upload.current) {
    const { uploadElement } = upload.current
    console.log(uploadElement)
    uploadElement.addEventListener("click", () => {
      console.log("click")
    })
  }
}, [])

const handleUpload = () => {
  const x = document.createElement("INPUT")
  x.setAttribute("type", "file")
  x.setAttribute("accept", "image/x-png,image/gif,image/jpeg")
  x.addEventListener("change", () => {
    // 模拟进度
    setProgress(0)
    setTimeout(() => {
      setProgress(20)
    }, 200)
    setTimeout(() => {
      setProgress(80)
    }, 500)
    setTimeout(() => {
      setProgress(100)
    }, 1000)
    setTimeout(() => {
      setProgress(null)
      setSrc(link)
    }, 1300)
  })
  x.click()
}

return (
  <Upload.Img
    ref={upload}
    progress={progress}
    src={src}
    onIconClick={(e) => {
      e.stopPropagation()
      setSrc("")
    }}
    previewDisabled
    onUpload={handleUpload}
    icon="replace"
    hoverOperations={[
      {
        text: "更改",
        onClick: (e) => {
          e.stopPropagation()
          setSrc("")
          handleUpload()
        },
      },
      {
        text: "删除",
        onClick: (e) => {
          e.stopPropagation()
          setSrc("")
        },
      },
    ]}
  />
)
```
