Swift HTTP Types are version-independent HTTP currency types designed for both clients and servers. They provide a common set of representations for HTTP requests and responses, focusing on modern HTTP features.
Add the following dependency clause to your Package.swift:
dependencies: [
.package(url: "https://github.com/apple/swift-http-types.git", from: "1.0.0")
]The HTTPTypes library exposes the core HTTP currency types, including HTTPRequest, HTTPResponse, and HTTPFields.
The HTTPTypesFoundation library provides conveniences for using new HTTP types with Foundation, including bidirectional convertors between the new types and Foundation URL types, and URLSession convenience methods with the new types.
The NIOHTTPTypes, NIOHTTPTypesHTTP1, and NIOHTTPTypesHTTP2 libraries provide channel handlers for translating the version-specific NIO HTTP types with the new HTTP types. They can be found in swift-nio-extras.
let request = HTTPRequest(method: .get, scheme: "https", authority: "www.example.com", path: "/")var request = HTTPRequest(method: .get, url: URL(string: "https://www.example.com/")!)
request.method = .post
request.path = "/upload"let response = HTTPResponse(status: .ok)extension HTTPField.Name {
static let myCustomHeader = Self("My-Custom-Header")!
}
// Set
request.headerFields[.userAgent] = "MyApp/1.0"
request.headerFields[.myCustomHeader] = "custom-value"
request.headerFields[values: .acceptLanguage] = ["en-US", "zh-Hans-CN"]
// Get
request.headerFields[.userAgent] // "MyApp/1.0"
request.headerFields[.myCustomHeader] // "custom-value"
request.headerFields[.acceptLanguage] // "en-US, zh-Hans-CN"
request.headerFields[values: .acceptLanguage] // ["en-US", "zh-Hans-CN"]var request = HTTPRequest(method: .post, url: URL(string: "https://www.example.com/upload")!)
request.headerFields[.userAgent] = "MyApp/1.0"
let (responseBody, response) = try await URLSession.shared.upload(for: request, from: requestBody)
guard response.status == .created else {
// Handle error
}channel.configureHTTP2Pipeline(mode: .server) { channel in
channel.pipeline.addHandlers([
HTTP2FramePayloadToHTTPServerCodec(),
ExampleChannelHandler()
])
}.map { _ in () }final class ExampleChannelHandler: ChannelDuplexHandler {
typealias InboundIn = HTTPTypeServerRequestPart
typealias OutboundOut = HTTPTypeServerResponsePart
func channelRead(context: ChannelHandlerContext, data: NIOAny) {
switch unwrapInboundIn(data) {
case .head(let request):
// Handle request headers
case .body(let body):
// Handle request body
case .end(let trailers):
// Handle complete request
let response = HTTPResponse(status: .ok)
context.write(wrapOutboundOut(.head(response)), promise: nil)
context.writeAndFlush(wrapOutboundOut(.end(nil)), promise: nil)
}
}
}For the most part, HTTP Types development is as straightforward as any other SwiftPM project. With that said, we do have a few processes that are worth understanding before you contribute. For details, please see CONTRIBUTING.md in this repository.
Please note that all work on HTTP Types is covered by the Swift HTTP Types Code of Conduct.
