ClientConfig¶

Redirect client log output to a Python logger. Write-only.

Request timeout in milliseconds.

Server URL to connect to. Required before any connect.

A complete EndpointDescription that pins the exact endpoint.

Usually taken from Client.getEndpoints(), and set instead of letting the client select an endpoint from endpointUrl and the security settings.

MessageSecurityMode to request; see o6.SecurityMode.

Full URI of the security policy to request.

Security policy as a short name, e.g. "Basic256Sha256".

An enum-friendly view of securityPolicyUri; the setter also accepts an o6.SecurityPolicy member.

URI advertised in the ApplicationDescription.

On a secured channel this must match the URI inside the client certificate.

The whole ApplicationDescription, for full control over discovery data.

User identity token sent on ActivateSession, as an ExtensionObject.

The setUsernamePassword and setAuthenticationCert methods fill this in for the common cases.

UserTokenPolicy that the identity token is encrypted for.

Operate on the SecureChannel alone, without creating a Session.

Set by Client.connectSecureChannel(); assigning it directly is not how a channel-only connection is established.

Do not reconnect automatically after the connection is lost.

Do not create a replacement Session when the old one cannot be reused.

Set SO_REUSEADDR on the client socket.

Permit a username/password token on an unencrypted channel.

Off by default, because it sends the password in clear text.

Session name shown by the server's session diagnostics.

Requested SecureChannel lifetime in milliseconds, before renewal.

Requested Session timeout in milliseconds.

Keepalive interval in milliseconds. 0 disables the check.

How many Publish requests are kept in flight for subscriptions.

Security policy URI used to encrypt the user identity token.

Defaults to the channel's own policy.

Byte limit for the trust list. 0 means no limit.

Maximum number of rejected certificates kept. 0 means no limit.

Preferred locale IDs for the Session, most preferred first.

Namespace URIs the client itself declares, indexed as given.

Transport send-buffer size in bytes.

Transport receive-buffer size in bytes.

Largest message the client accepts, in bytes. 0 means no limit.

Largest number of chunks the client accepts. 0 means no limit.

The client's own certificate, as DER bytes.

Accepts a path string, a Path, or raw DER or PEM bytes; reads back as DER. Setting it stores the value until it is applied on connect.

The client's own private key, as DER bytes.

Accepts a path string, a Path, or raw DER or PEM bytes.

Certificates the client trusts, as DER bytes.

Accepts path strings, Path objects, or raw DER or PEM bytes.

Certificate revocation lists for trustList, as DER bytes.
