Struct actix_web::dev::ServiceRequest

pub struct ServiceRequest { /* private fields */ }

A service level request wrapper.

Allows mutable access to request’s internal structures.

Implementations

impl ServiceRequest

pub fn into_parts(self) -> (HttpRequest, Payload)

Deconstruct ServiceRequest into inner parts.

pub fn parts_mut(&mut self) -> (&mut HttpRequest, &mut Payload)

Returns mutable accessors to inner parts.

pub fn parts(&self) -> (&HttpRequest, &Payload)

Returns immutable accessors to inner parts.

pub fn request(&self) -> &HttpRequest

Returns immutable accessor to inner HttpRequest.

pub fn extract<T>(&mut self) -> <T as FromRequest>::Futurewhere
    T: FromRequest,

Derives a type from this request using an extractor.

Returns the T extractor’s Future type which can be awaited. This is particularly handy when you want to use an extractor in a middleware implementation.

Examples

use actix_web::{
    dev::{ServiceRequest, ServiceResponse},
    web::Path, Error
};

async fn my_helper(mut srv_req: ServiceRequest) -> Result<ServiceResponse, Error> {
    let path = srv_req.extract::<Path<(String, u32)>>().await?;
    // [...]
}

pub fn from_parts(req: HttpRequest, payload: Payload) -> Self

Construct request from parts.

pub fn from_request(req: HttpRequest) -> Self

Construct ServiceRequest with no payload from given HttpRequest.

pub fn into_response<B, R: Into<Response<B>>>(self, res: R) -> ServiceResponse<B>

Create ServiceResponse from this request and given response.

pub fn error_response<E: Into<Error>>(self, err: E) -> ServiceResponse

Create ServiceResponse from this request and given error.

pub fn head(&self) -> &RequestHead

Returns a reference to the request head.

pub fn head_mut(&mut self) -> &mut RequestHead

Returns a mutable reference to the request head.

pub fn uri(&self) -> &Uri

Returns the request URI.

pub fn method(&self) -> &Method

Returns the request method.

pub fn version(&self) -> Version

Returns the request version.

pub fn headers(&self) -> &HeaderMap

Returns a reference to request headers.

pub fn headers_mut(&mut self) -> &mut HeaderMap

Returns a mutable reference to request headers.

pub fn path(&self) -> &str

Returns request path.

pub fn query_string(&self) -> &str

Counterpart to HttpRequest::query_string.

pub fn peer_addr(&self) -> Option<SocketAddr>

Returns peer’s socket address.

Peer address is the directly connected peer’s socket address. If a proxy is used in front of the Actix Web server, then it would be address of this proxy.

To get client connection information ConnectionInfo should be used.

Will only return None when called in unit tests.

pub fn connection_info(&self) -> Ref<'_, ConnectionInfo>

Returns a reference to connection info.

pub fn match_info(&self) -> &Path<Url>

Returns reference to the Path parameters.

Params is a container for URL parameters. A variable segment is specified in the form {identifier}, where the identifier can be used later in a request handler to access the matched value for that segment.

pub fn match_info_mut(&mut self) -> &mut Path<Url>

Returns a mutable reference to the path match information.

pub fn match_name(&self) -> Option<&str>

Counterpart to HttpRequest::match_name.

pub fn match_pattern(&self) -> Option<String>

Counterpart to HttpRequest::match_pattern.

pub fn resource_map(&self) -> &ResourceMap

Returns a reference to the application’s resource map.

pub fn app_config(&self) -> &AppConfig

Returns a reference to the application’s configuration.

pub fn app_data<T: 'static>(&self) -> Option<&T>

Counterpart to HttpRequest::app_data.

pub fn conn_data<T: 'static>(&self) -> Option<&T>

Counterpart to HttpRequest::conn_data.

pub fn cookies(&self) -> Result<Ref<'_, Vec<Cookie<'static>>>, CookieParseError>

Return request cookies.

pub fn cookie(&self, name: &str) -> Option<Cookie<'static>>

Return request cookie.

pub fn set_payload(&mut self, payload: Payload)

Set request payload.

pub fn add_data_container(&mut self, extensions: Rc<Extensions>)

Add data container to request’s resolution set.

In middleware, prefer extensions_mut for request-local data since it is assumed that the same app data is presented for every request.

pub fn guard_ctx(&self) -> GuardContext<'_>

Creates a context object for use with a guard.
