HTTP client

You can use the http namespace of the Runnable API to make HTTP requests from your Runnable code. These methods are currently the only way to access the network from Runnable code.

Arbitrary socket and network access is not currently possible.

Rust

In Rust these methods are available under the http module:

# Use the "http" module
use suborbital::http;

# Invoke the "Get" method
http::get(…)

JavaScript/TypeScript 🧪

In JavaScript and TypeScript the methods live on the http import:

import { http } from "@suborbital/runnable"

All HTTP requests return a HttpResponse object supporting various payload formats:

export class HttpResponse {
  arrayBuffer(): ArrayBuffer {}

  json(): object {}

  text(): string {}
}

The headers parameter may be specified as string header name/value pairs:

type Headers = { [key: string]: string };

AssemblyScript 🧪

In AssemblyScript all methods are prefixed with http:

// Import then invoke "Get" method
import { httpGet } from '@suborbital/suborbital'

httpGet(…)

Swift 🧪

In Swift these methods are prefixed with Http:

// Invoke the "Get" method
Suborbital.HttpGet(…)

note

Swift does not yet support passing headers to a request.

The following namespace methods are available:

GET

Performs an HTTP GET request:

Rust

STATUS: STABLE

pub fn get(url: &str, headers: Option<BTreeMap<&str, &str>>) -> Result<Vec<u8>, RunErr>

JavaScript & TypeScript

STATUS: BETA

http.get(url: string, headers?: Headers): HttpResponse

AssemblyScript

STATUS: BETA

function httpGet(url: string, headers: Map<string, string> | null): ArrayBuffer

Swift

STATUS: PREVIEW

public func HttpGet(url: String) -> String

POST

Performs an HTTP POST request:

Rust

STATUS: STABLE

pub fn post(url: &str, body: Option<Vec<u8>>, headers: Option<BTreeMap<&str, &str>>) -> Result<Vec<u8>, RunErr>

JavaScript & TypeScript

STATUS: BETA

http.post(url: string, body: string | Uint8Array, headers?: Headers): HttpResponse

AssemblyScript

STATUS: BETA

function httpPost(url: string, body: ArrayBuffer, headers: Map<string, string> | null): ArrayBuffer

Swift

STATUS: PREVIEW

public func HttpPost(url: String, body: String) -> String

PATCH

Performs an HTTP PATCH request:

Rust

STATUS: STABLE

pub fn patch(url: &str, body: Option<Vec<u8>>, headers: Option<BTreeMap<&str, &str>>) -> Result<Vec<u8>, RunErr>

JavaScript & TypeScript

STATUS: BETA

http.patch(url: string, body: string | Uint8Array, headers?: Headers): HttpResponse

AssemblyScript

STATUS: BETA

function httpPatch(url: string, body: ArrayBuffer, headers: Map<string, string> | null): ArrayBuffer

Swift

STATUS: PREVIEW

public func HttpPatch(url: String, body: String) -> String

DELETE

Performs an HTTP DELETE request:

Rust

STATUS: STABLE

pub fn delete(url: &str, headers: Option<BTreeMap<&str, &str>>) -> Result<Vec<u8>, RunErr>

JavaScript & TypeScript

STATUS: BETA

http.delete(url: string, headers?: Headers): HttpResponse

AssemblyScript

STATUS: BETA

function httpDelete(url: string, headers: Map<string, string> | null): ArrayBuffer

Swift

STATUS: PREVIEW

public func HttpDelete(url: String) -> String
