[][src]Struct actix_web::http::header::ContentDisposition

pub struct ContentDisposition {
    pub disposition: DispositionType,
    pub parameters: Vec<DispositionParam>,
}

A Content-Disposition header. It is compatible to be used either as a response header for the main body as (re)defined in RFC6266, or as a header for a multipart body as (re)defined in RFC7587.

In a regular HTTP response, the Content-Disposition response header is a header indicating if the content is expected to be displayed inline in the browser, that is, as a Web page or as part of a Web page, or as an attachment, that is downloaded and saved locally, and also can be used to attach additional metadata, such as the filename to use when saving the response payload locally.

In a multipart/form-data body, the HTTP Content-Disposition general header is a header that can be used on the subpart of a multipart body to give information about the field it applies to. The subpart is delimited by the boundary defined in the Content-Type header. Used on the body itself, Content-Disposition has no effect.

ABNF

content-disposition = "Content-Disposition" ":"
                      disposition-type *( ";" disposition-parm )

disposition-type    = "inline" | "attachment" | disp-ext-type
                      ; case-insensitive

disp-ext-type       = token

disposition-parm    = filename-parm | disp-ext-parm

filename-parm       = "filename" "=" value
                    | "filename*" "=" ext-value

disp-ext-parm       = token "=" value
                    | ext-token "=" ext-value

ext-token           = <the characters in token, followed by "*">

Note: filename* must not be used within multipart/form-data.

Example

use actix_web::http::header::{
    Charset, ContentDisposition, DispositionParam, DispositionType,
    ExtendedValue,
};

let cd1 = ContentDisposition {
    disposition: DispositionType::Attachment,
    parameters: vec![DispositionParam::FilenameExt(ExtendedValue {
        charset: Charset::Iso_8859_1, // The character set for the bytes of the filename
        language_tag: None, // The optional language tag (see `language-tag` crate)
        value: b"\xa9 Copyright 1989.txt".to_vec(), // the actual bytes of the filename
    })],
};
assert!(cd1.is_attachment());
assert!(cd1.get_filename_ext().is_some());

let cd2 = ContentDisposition {
    disposition: DispositionType::FormData,
    parameters: vec![
        DispositionParam::Name(String::from("file")),
        DispositionParam::Filename(String::from("bill.odt")),
    ],
};
assert_eq!(cd2.get_name(), Some("file")); // field name
assert_eq!(cd2.get_filename(), Some("bill.odt"));

WARN

If "filename" parameter is supplied, do not use the file name blindly, check and possibly change to match local file system conventions if applicable, and do not use directory path information that may be present. See RFC2183 .
