web.py获取上传文件名的正确方法

web.py

直接切入主题,从HTML页面上传文件,Python接收处理。但其中发现有些小问题,把它写出来,算是积累吧!

HTML页面代码:

代码如下:



   


Python处理部分代码:

代码如下:


i=web.input()
return i.image.filename


执行结果切提示:

代码如下:


at /admin/addgoodsaction/
'str' object has no attribute 'filename'


提示这个对象没有找到filename这个属性,一开始以为是接收对象错了,于是我直接

代码如下:


i=web.input()
return i.image


结果能正常打印上传的图片。证明接收对象没有错误,可为什么接收的对象正确,却提示没有filename这个属性呢?
我改写了一下代码:

代码如下:


i=web.input(image={})
return i.image.filename


上传一个hello.jpg的图片,结果打印hello.jpg,问题解决。从以上代码看如果不初始化image对象就找不到filename这个属性,而初始化以后才能获取filename属性从而获取上传的文件名。
