页面没有文件上传输入框

Error message

页面没有文件上传输入框

What it means

This error is thrown by findImageUploadInput when the Xiaohongshu publish page DOM contains no `input[type="file"]` elements. The library relies on a native file input to call rod's SetFiles for image uploads; without such an input it cannot proceed. It typically means the page did not load into the expected upload state or XHS changed its upload widget markup.

Solutions

1. Verify the browser is still on the image publish page (URL contains /publish/publish) before calling uploadImages
2. Increase wait for the page/upload widget to render before the first upload (wait for `.upload-input` or the upload area to appear)
3. Check if Xiaohongshu changed the DOM; update the `input[type="file"]` selector in findImageUploadInput accordingly
4. Retry uploadImages; transient rendering races often resolve on a second run

Example fix

// before
if len(inputs) == 0 {
	return nil, errors.New("页面没有文件上传输入框")
}
// after
if len(inputs) == 0 {
	// wait briefly for lazy-rendered input
	_ = page.WaitElementsMoreThan(`input[type="file"]`, 0, 5*time.Second) // or fallback to .upload-input
}

func hasFileInput(page *rod.Page) bool {
	inputs, err := page.Elements(`input[type="file"]`)
	return err == nil && len(inputs) > 0
}

for attempt := 0; attempt < 3; attempt++ {
	if err := uploadImages(page, paths); err == nil {
		break
	} else if strings.Contains(err.Error(), "页面没有文件上传输入框") {
		time.Sleep(3 * time.Second) // 等页面渲染后重试
		continue
	}
	return err
}

When it happens

Trigger: uploadImages calls findImageUploadInput for the 2nd..Nth image (first image uses `.upload-input`); the selector `input[type="file"]` matches zero elements — e.g. page still loading, previous upload navigated away, or the DOM was re-rendered removing the hidden input.

Common situations: Slow network leaving the publish page half-rendered; XHS frontend update that lazy-creates the file input only after a click; calling uploadImages after the page already navigated; a modal/overlay replacing the upload area mid-loop.
