pub struct AuthMiddleware { /* private fields */ }Expand description
A middleware that adds basic authentication to requests.
Uses a cache to propagate credentials from previously seen requests and fetches credentials from a netrc file, TOML file, and the keyring.
Implementations§
Source§impl AuthMiddleware
impl AuthMiddleware
pub fn new() -> Self
Sourcepub fn with_netrc(self, netrc: Option<Netrc>) -> Self
pub fn with_netrc(self, netrc: Option<Netrc>) -> Self
Configure the Netrc credential file to use.
None disables authentication via netrc.
Sourcepub fn with_text_store(self, store: Option<TextCredentialStore>) -> Self
pub fn with_text_store(self, store: Option<TextCredentialStore>) -> Self
Configure the text credential store to use.
None disables authentication via text store.
Sourcepub fn with_keyring(self, keyring: Option<KeyringProvider>) -> Self
pub fn with_keyring(self, keyring: Option<KeyringProvider>) -> Self
Configure the KeyringProvider to use.
Sourcepub fn with_preview(self, preview: Preview) -> Self
pub fn with_preview(self, preview: Preview) -> Self
Configure the Preview features to use.
Sourcepub fn with_cache(self, cache: CredentialsCache) -> Self
pub fn with_cache(self, cache: CredentialsCache) -> Self
Configure the CredentialsCache to use.
Sourcepub fn with_cache_arc(self, cache: Arc<CredentialsCache>) -> Self
pub fn with_cache_arc(self, cache: Arc<CredentialsCache>) -> Self
Configure the CredentialsCache to use from an existing Arc.
Sourcepub fn with_indexes(self, indexes: Indexes) -> Self
pub fn with_indexes(self, indexes: Indexes) -> Self
Configure the AuthPolicys to use for URLs.
Sourcepub fn with_only_authenticated(self, only_authenticated: bool) -> Self
pub fn with_only_authenticated(self, only_authenticated: bool) -> Self
Set all endpoints as needing authentication. We never try to send an unauthenticated request, avoiding cloning an uncloneable request.
Sourcepub fn with_base_client(self, client: ClientWithMiddleware) -> Self
pub fn with_base_client(self, client: ClientWithMiddleware) -> Self
Configure the ClientWithMiddleware to use for requests within the middleware.
Sourcepub fn with_pyx_token_store(self, token_store: PyxTokenStore) -> Self
pub fn with_pyx_token_store(self, token_store: PyxTokenStore) -> Self
Configure the PyxTokenStore to use for persistent credentials.

'life2: 'async_trait,
Handle authentication for a request.
§If the request has a username and password
We already have a fully authenticated request and we don’t need to perform a look-up.
- Perform the request
- Add the username and password to the cache if successful
§If the request only has a username
We probably need additional authentication, because a username is provided. We’ll avoid making a request we expect to fail and look for a password. The discovered credentials must have the requested username to be used.
- Check the cache (index URL or realm key) for a password
- Check the netrc for a password
- Check the keyring for a password
- Perform the request
- Add the username and password to the cache if successful
§If the request has no authentication
We may or may not need authentication. We’ll check for cached credentials for the URL, which is relatively specific and can save us an expensive failed request. Otherwise, we’ll make the request and look for less-specific credentials on failure i.e. if the server tells us authorization is needed. This pattern avoids attaching credentials to requests that do not need them, which can cause some servers to deny the request.
- Check the cache (URL key)
- Perform the request
- On 401, 403, or 404 check for authentication if there was a cache miss
- Check the cache (index URL or realm key) for the username and password
- Check the netrc for a username and password
- Perform the request again if found
- Add the username and password to the cache if successful
