This class is used internally by FieldStorage and is not
meant to be instantiated by the user. Each instance of a Field
class represents an HTML Form input.
Field instances have the following attributes:
- name
-
The input name.
- value
-
The input value. This attribute can be used to read data from a file
upload as well, but one has to exercise caution when dealing with
large files since when accessed via value, the whole file is
read into memory.
- file
-
This is a file object. For file uploads it points to a temporary file.
For simple values, it is a StringIO object, so you can read
simple string values via this attribute instead of using the value
attribute as well.
- filename
-
The name of the file as provided by the client.
- type
-
The content-type for this input as provided by the client.
- type_options
-
This is what follows the actual content type in the
content-type
header provided by the client, if anything. This is a dictionary.
- disposition
-
The value of the first part of the
content-disposition header.
- disposition_options
-
The second part (if any) of the
content-disposition header in
the form of a dictionary.
