Enum vector::http::HttpClientAuthorizationStrategy

pub enum HttpClientAuthorizationStrategy {
    Basic {
        user: String,
        password: SensitiveString,
    },
    OAuth2 {
        token_endpoint: String,

        grace_period: u32,
    },
}

Configuration of the authentication strategy for HTTP requests.

HTTP authentication should be used with HTTPS only, as the authentication credentials are passed as an HTTP header without any additional encryption beyond what is provided by the transport itself.

Variants

Basic

Basic authentication.

The username and password are concatenated and encoded via base64.

Fields

user: String

The basic authentication username.

password: SensitiveString

The basic authentication password.

OAuth2

Authentication based on OAuth 2.0 protocol.

This strategy allows to dynamically acquire and use token based on provided parameters. Both standard client_credentials and mTLS extension is supported, for standard client_credentials just provide both client_id and client_secret parameters:

Example

strategy:
 strategy: "o_auth2"
 client_id: "client.id"
 client_secret: "secret-value"
 token_endpoint: "https://yourendpoint.com/oauth/token"

In case you want to use mTLS extension rfc8705, provide desired key and certificate, together with client_id (with no client_secret parameter).

Example

strategy:
 strategy: "o_auth2"
 client_id: "client.id"
 token_endpoint: "https://yourendpoint.com/oauth/token"
tls:
 crt_path: cert.pem
 key_file: key.pem

Fields

token_endpoint: String

Token endpoint location, required for token acquisition.

client_id: String

The client id.

client_secret: Option<SensitiveString>

The sensitive client secret.

grace_period: u32

The grace period configuration for a bearer token. To avoid random authorization failures caused by expired token exception, we will acquire new token, some time (grace period) before current token will be expired, because of that, we will always execute request with fresh enough token.
