Struct actix_http::ResponseBuilder [−][src]
pub struct ResponseBuilder { /* fields omitted */ }
Expand description
An HTTP response builder.
Used to construct an instance of Response
using a builder pattern. Response builders are often
created using Response::build
.
Examples
use actix_http::{Response, ResponseBuilder, body, http::StatusCode, http::header}; let mut res: Response<_> = Response::build(StatusCode::OK) .content_type(mime::APPLICATION_JSON) .insert_header((header::SERVER, "my-app/1.0")) .append_header((header::SET_COOKIE, "a=1")) .append_header((header::SET_COOKIE, "b=2")) .body("1234"); assert_eq!(res.status(), StatusCode::OK); assert!(res.headers().contains_key("server")); assert_eq!(res.headers().get_all("set-cookie").count(), 2); assert_eq!(body::to_bytes(res.into_body()).await.unwrap(), &b"1234"[..]);
Implementations
Create response builder
Examples
use actix_http::{Response, ResponseBuilder, http::StatusCode}; let res: Response<_> = ResponseBuilder::default().finish(); assert_eq!(res.status(), StatusCode::OK);
Set HTTP status code of this response.
Examples
use actix_http::{ResponseBuilder, http::StatusCode}; let res = ResponseBuilder::default().status(StatusCode::NOT_FOUND).finish(); assert_eq!(res.status(), StatusCode::NOT_FOUND);
Insert a header, replacing any that were set with an equivalent field name.
Examples
use actix_http::{ResponseBuilder, http::header}; let res = ResponseBuilder::default() .insert_header((header::CONTENT_TYPE, mime::APPLICATION_JSON)) .insert_header(("X-TEST", "value")) .finish(); assert!(res.headers().contains_key("content-type")); assert!(res.headers().contains_key("x-test"));
Append a header, keeping any that were set with an equivalent field name.
Examples
use actix_http::{ResponseBuilder, http::header}; let res = ResponseBuilder::default() .append_header((header::CONTENT_TYPE, mime::APPLICATION_JSON)) .append_header(("X-TEST", "value1")) .append_header(("X-TEST", "value2")) .finish(); assert_eq!(res.headers().get_all("content-type").count(), 1); assert_eq!(res.headers().get_all("x-test").count(), 2);
Set the custom reason for the response.
Set connection type to KeepAlive
Set connection type to Upgrade
Force close connection, even if it is marked as keep-alive
Disable chunked transfer encoding for HTTP/1.1 streaming responses.
Set response content type.
