# Individual file
|
|
|
|
It is possible to serve static files with a custom path pattern and `NamedFile`. To
|
|
match a path tail, we can use a `[.*]` regex.
|
|
|
|
```rust
|
|
extern crate actix_web;
|
|
use std::path::PathBuf;
|
|
use actix_web::{App, HttpRequest, Result, http::Method, fs::NamedFile};
|
|
|
|
fn index(req: &HttpRequest) -> Result<NamedFile> {
|
|
let path: PathBuf = req.match_info().query("tail")?;
|
|
Ok(NamedFile::open(path)?)
|
|
}
|
|
|
|
fn main() {
|
|
App::new()
|
|
.resource(r"/a/{tail:.*}", |r| r.method(Method::GET).f(index))
|
|
.finish();
|
|
}
|
|
```
|
|
|
|
# Directory
|
|
|
|
To serve files from specific directories and sub-directories, `StaticFiles` can be used.
|
|
`StaticFiles` must be registered with an `App::handler()` method, otherwise
|
|
it will be unable to serve sub-paths.
|
|
|
|
```rust
|
|
extern crate actix_web;
|
|
use actix_web::{App, fs};
|
|
|
|
fn main() {
|
|
App::new()
|
|
.handler(
|
|
"/static",
|
|
fs::StaticFiles::new(".")
|
|
.unwrap()
|
|
.show_files_listing())
|
|
.finish();
|
|
}
|
|
```
|
|
|
|
The parameter is the base directory. By default files listing for sub-directories
|
|
is disabled. Attempt to load directory listing will return *404 Not Found* response.
|
|
To enable files listing, use
|
|
[*StaticFiles::show_files_listing()*](../../actix-web/actix_web/fs/struct.StaticFiles.html#method.show_files_listing)
|
|
method.
|
|
|
|
Instead of showing files listing for directory, it is possible to redirect
|
|
to a specific index file. Use the
|
|
[*StaticFiles::index_file()*](../../actix-web/actix_web/fs/struct.StaticFiles.html#method.index_file)
|
|
method to configure this redirect.
|
|
|
|
# Configuration
|
|
|
|
Generic trait `StaticFileConfig` can be used to specify various options
|
|
for serving files:
|
|
|
|
- `content_disposition_map` - function to be used for mapping file's mime to corresponding `Content-Disposition` type
|
|
- `is_use_etag` - specifies whether `ETag` shall be calculated and included in headers.
|
|
- `is_use_last_modifier` - specifies whether file modified timestamp should be used and added to `Last-Modified` header.
|
|
- `is_method_allowed` - allows to control which HTTP methods are allowed to be used when accessing file.
|
|
|
|
All of the above methods are optional and provided with the best defaults.
|
|
But it is possible to customize any of them by implementing the trait onto own struct.
|
|
|
|
```rust
|
|
extern crate mime;
|
|
extern crate actix_web;
|
|
use actix_web::{App, HttpRequest, Result, http::Method};
|
|
use actix_web::fs::{StaticFileConfig, NamedFile};
|
|
use actix_web::http::header::DispositionType;
|
|
|
|
use std::path::PathBuf;
|
|
|
|
#[derive(Default)]
|
|
struct MyConfig;
|
|
|
|
impl StaticFileConfig for MyConfig {
|
|
fn content_disposition_map(typ: mime::Name) -> DispositionType {
|
|
DispositionType::Attachment
|
|
}
|
|
}
|
|
|
|
fn index(req: &HttpRequest) -> Result<NamedFile<MyConfig>> {
|
|
let path: PathBuf = req.match_info().query("tail")?;
|
|
Ok(NamedFile::open_with_config(path, MyConfig)?)
|
|
}
|
|
|
|
fn main() {
|
|
App::new()
|
|
.resource(r"/a/{tail:.*}", |r| r.method(Method::GET).f(index))
|
|
.finish();
|
|
}
|
|
```
|
|
|
|
The Configuration cal also be applied to directory service:
|
|
|
|
```rust
|
|
extern crate actix_web;
|
|
|
|
use actix_web::{App};
|
|
use actix_web::fs::{StaticFileConfig, StaticFiles};
|
|
|
|
#[derive(Default)]
|
|
struct MyConfig;
|
|
|
|
impl StaticFileConfig for MyConfig {
|
|
fn is_use_etag() -> bool {
|
|
false
|
|
}
|
|
|
|
fn is_use_last_modifier() -> bool {
|
|
false
|
|
}
|
|
}
|
|
|
|
fn main() {
|
|
App::new()
|
|
.handler(
|
|
"/static",
|
|
StaticFiles::with_config(".", MyConfig).unwrap()
|
|
.show_files_listing()
|
|
).finish();
|
|
}
|
|
```
