WebSocketClient's TLS setup already threaded
ClientTlsSessionOptions::server_hostname_verification through
setup_client_tls_session(), the same path SSLClient uses, but never
exposed a way to set it: create_stream() called setup_client_tls_session()
without an options argument, so the default (verification on) was the
only reachable value.
Add the public setter, mirroring ClientImpl/SSLClient/Client, and wire
it into create_stream()'s ClientTlsSessionOptions. Last open item from
issue #2531's WebSocketClient/SSLClient API alignment.
Issue #2531 asked for connect() to expose error detail the way
ClientImpl/SSLClient do via Result, instead of collapsing every failure
into a bare bool. The groundwork (detail::ClientTlsSessionError) was
already laid during the WebSocketClient/SSLClient dedup but left
unwired.
- Add httplib::ws::Result: explicit operator bool(), error(), and
flattened upgrade-response accessors (status(), headers(),
get_header_value(), has_header()); ssl_error()/ssl_backend_error() on
SSL builds.
- Add Error::WebSocketHandshake for upgrade-validation failures
(non-101 status, bad Sec-WebSocket-Accept, bad Upgrade/Connection
headers).
- Extract detail::parse_status_line from ClientImpl::read_response_line
and reuse it in read_websocket_upgrade_response, replacing the
previous "HTTP/1.1 101" substring match with a proper parse. Non-101
responses now surface their status and headers instead of being read
and discarded.
- Wire WebSocketClient::create_stream() to capture ClientTlsSessionError
so TLS failures (SSLServerVerification, SSLServerHostnameVerification,
...) reach the caller with backend error codes.
- Update tests and README-websocket.md accordingly.
This is a source-breaking change for callers that assign the result to
bool (e.g. bool ok = cli.connect();); if (cli.connect()) and gtest's
ASSERT_TRUE/EXPECT_FALSE(...) macros are unaffected since operator bool
still participates in contextual conversion.
WebSocketClient::set_connection_timeout (both the time_t and
chrono overloads) was missing from README-websocket.md's API
reference and the timeout example, even though set_read_timeout
and set_write_timeout were both listed.
README.md never documented the PemMemory in-memory constructor
that SSLServer and SSLClient both have, so mTLS setup only showed
the file-path form. Add a "Mutual TLS (mTLS)" section covering
both forms for server and client, and note that
ws::WebSocketClient's wss:// constructor takes the same PemMemory
struct.
Also note, next to Client::set_interface, that WebSocketClient has
the same method, matching the existing cross-reference for
set_hostname_addr_map right below it.
Adds ws::WebSocketClient::PemMemory and a constructor overload that
installs an in-memory client certificate on the TLS context, enabling
mutual TLS for wss:// connections. The certificate is silently ignored
for ws:// URLs, consistent with the existing TLS-only setters such as
set_ca_cert_path().
Part of the interface alignment discussed in #2531.
WebSocketClient::set_ca_cert_path took a single path and create_stream()
hardcoded an empty directory when calling detail::load_client_ca_config, while
ClientImpl has always accepted (ca_cert_file_path, ca_cert_dir_path = ""). Give
WebSocketClient the same signature and store the directory, so both clients
configure CA loading identically. The one-argument form is unchanged for
callers.
Also note at both call sites why the "load the CA config once" guard differs:
SSLClient needs call_once because one client serves concurrent requests, and
WebSocketClient does not because connect() is not safe to call concurrently
anyway.
- Added `set_websocket_max_missed_pongs` method to configure unresponsive-peer detection.
- Updated README and documentation to clarify WebSocket limitations and features.
- Introduced tests for detecting non-responsive peers and ensuring responsive peers do not trigger timeouts.
