Django中的图片上传

1、View

# ImageFile类继承File类，扩展了width和height属性
    file_hpic = ImageFile(request.FILES["hpic"])
    # 检查文件的格式、大小、宽高
    if file_hpic.name.endswith(".jpg") and round(file_hpic.size / 1024, 1) <= 300 \
        and 200 <= file_hpic.width <= 300 and 200 <= file_hpic.height <= 300:
        # 对图片进行编号
        file_name = str(uuid.uuid1()) + os.path.splitext(file_hpic.name)[1]
        file_path = os.path.join(settings.MEDIA_ROOT, "book", file_name)
        # 文件上传1--上传到服务器
        with open(file_path, "wb") as file:
            for chunk in file_hpic.chunks():
                file.write(chunk)

        # 文件上传2--写入到数据库中
        hero.hpic = os.path.join("book", file_name)

2、Template

3、备注

上传的图片文件夹配置，需要在项目目录的settings.py文件添加：
MEDIA_ROOT = os.path.join(BASE_DIR, 'static/media')
