Challenge.deserialize

Deserializes a WWW-Authenticate header value to a Challenge.

Usage

import { Challenge } from 'mppx'
 
const header = 'Payment id="abc123", realm="mpp.dev", method="tempo", intent="charge", request="eyJhbW91bnQiOi..."'
const challenge = Challenge.deserialize(header)

With method type narrowing

Use a method definition to get type-safe access to method-specific request fields.

import { Challenge } from 'mppx'
import { Methods } from 'mppx/tempo'
 
const header = 'Payment id="abc123", realm="mpp.dev", method="tempo", intent="charge", request="eyJhbW91bnQiOi..."'
const challenge = Challenge.deserialize(header, { methods: [Methods.charge] })

Return type

type ReturnType = Challenge

The deserialized Challenge object. mppx decodes request and opaque from their base64url-encoded JCS strings back to structured values. If the serialized header contains an opaque parameter, the parsed value is accessible via Challenge.meta.

Parameters

options (optional)

• Type: { methods?: readonly Method.Method[] }

Optional settings to narrow the Challenge type using method intents.

value

• Type: string

The WWW-Authenticate header value.
