Struct Intercept

pub struct Intercept {
    pub temp_dir_path: Option<PathBuf>,
    pub file_size_limit: u64,
    pub file_count_limit: u32,
    pub limit_behavior: LimitBehavior,
}

A BeforeMiddleware for Iron which will intercept and read-out multipart requests and store the result in the request.

Successful reads will be placed in the extensions: TypeMap field of iron::Request as an Entries instance (as both key-type and value):

extern crate iron;
extern crate qiniu_multipart;

use iron::prelude::*;

use qiniu_multipart::server::Entries;
use qiniu_multipart::server::iron::Intercept;

fn main() {
    let mut chain = Chain::new(|req: &mut Request| if let Some(entries) =
        req.extensions.get::<Entries>() {

        Ok(Response::with(format!("{:?}", entries)))
    } else {
        Ok(Response::with("Not a multipart request"))
    });

    chain.link_before(Intercept::default());

    Iron::new(chain).http("localhost:80").unwrap();
}

Any errors during which occur during reading will be passed on as IronError.

Fields

temp_dir_path: Option<PathBuf>

The parent directory for all temporary directories created by this middleware. Will be created if it doesn’t exist (lazy).

If omitted, uses the OS temporary directory.

Default value: None.

file_size_limit: u64

The size limit of uploaded files, in bytes.

Files which exceed this size will be rejected. See the limit_behavior field for more info.

Default value: DEFAULT_FILE_SIZE_LIMIT

file_count_limit: u32

The limit on the number of files which will be saved from the request. Requests which exceed this count will be rejected.

Default value: DEFAULT_FILE_COUNT_LIMT

limit_behavior: LimitBehavior

What to do when a file count or size limit has been exceeded.

See LimitBehavior for more info.
