javascript - 如何将图像发布到用户的墙上？

    }
  });

You do not want to make a post, but upload a photo to the user’s wall instead: https://developers.facebook.com/docs/reference/api/user/#photos

If you don’t want to do an actual HTTP upload of the photo data (hard to do from JS), but just have Facebook pull the photo from an URL – then use parameter url instead of source.
