python - "AttributeError: 'dict' object has no attribute 'filename'"
python2.7版本，使用Pycharm运行python项目的gui.py文件时提示app.py的第17行代码（也就是filename = i.file.filename）出错，错误信息：AttributeError: 'dict' object has no attribute 'filename'
但是代码已经对file进行了初始化了：
i = web.input(file = {}) #接收数据
filename = i.file.filename #获取文件名
file = i.file.file.read() #获取文件请问为啥还是出现这个错误？
html代码为：
<!DOCTYPE html>
<html>
<body>
<form action="/upload" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="post">
</form>
</body>
</html>gui.py代码为：
