用于图像审核Firebase函数的ChildProcessError [英] ChildProcessError for image moderation firebase function

问题描述

我正在尝试实施图像审核代码，以删除此处提供的成人或暴力内容: https://github.com/firebase/functions-samples/tree/master/generate-thumbnail

I'm trying implement image moderation code to remove adult or violent content as given here: https://github.com/firebase/functions-samples/tree/master/generate-thumbnail

但是每次我遇到此错误:

But every time i'm getting this error:

ChildProcessError: Command failed: convert /tmp/test folder/yes.jpg -channel RGBA -blur 0x8 /tmp/test folder/yes.jpg
convert: unable to open image `/tmp/test': No such file or directory @ error/blob.c/OpenBlob/2712.
convert: no decode delegate for this image format `' @ error/constitute.c/ReadImage/501.

    at maybeClose (internal/child_process.js:877:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:226:5)

由于此行:

// Blur the image using ImageMagick.
    return exec(`convert ${tempLocalFile} -channel RGBA -blur 0x8 ${tempLocalFile}`);

还有另一种帮助，是调节视频而不是图像的最佳方法是什么，即我是否要检查上传的视频是否令人反感(成人或暴力).

And one more help what is best way to moderate video instead of image, i.e. if i want to check if video uploaded is not offensive(adult or violent).

感谢您的帮助.

推荐答案

感谢fmw42的帮助，这是一个愚蠢的错误.命令中的问题仅包含空格，请尝试避免文件夹名称中包含空格.无论如何，如果您有认真的处理命令，例如:

Thanks fmw42 for help, it was silly mistake. Issue in command is with whitespaces only, try avoiding spaces in folder name. Anyway if you have handle command carefully like:

return exec(`convert "${tempLocalFile}" -channel RGBA -blur 0x8 "${tempLocalFile}"`);
