Django里面，通过Html页面提交的数据，可以通过在View里面定义的函数通过request参数获取。简单的说，主要可以分出3种情况。
-
HTML页面传递来的单个数据, 比如radiobox或者text 可以通过request.POST.get获取
-
HTML页面传递来多个数据，比如checkbox或者option， 可以通过request.POST.getlist获取
-
HTML页面上传了一个文件，html端需要表明enctype，表示这是一个文件而不是字符串；后台需要通过request.FILES.get获取这个文件的地址，然后通过chunk分块写入指定的地址
现在来看看实例:
