Enumeration Type Documentation

enum websocketpp::processor::error::processor_errors

Enumerator
general	Catch-all error for processor policy errors that don't fit in other categories.
bad_request	Error was the result of improperly formatted user input.
protocol_violation	Processor encountered a protocol violation in an incoming message.
message_too_big	Processor encountered a message that was too large.
invalid_payload	Processor encountered invalid payload data.
invalid_arguments	The processor method was called with invalid arguments.
invalid_opcode	Opcode was invalid for requested operation.
control_too_big	Control frame too large.
invalid_rsv_bit	Illegal use of reserved bit.
fragmented_control	Fragmented control message.
invalid_continuation	Continuation without message.
masking_required	Clients may not send unmasked frames.
masking_forbidden	Servers may not send masked frames.
non_minimal_encoding	Payload length not minimally encoded.
requires_64bit	Not supported on 32 bit systems.
invalid_utf8	Invalid UTF-8 encoding.
not_implemented	Operation required not implemented functionality.
invalid_http_method	Invalid HTTP method.
invalid_http_version	Invalid HTTP version.
invalid_http_status	Invalid HTTP status.
missing_required_header	Missing Required Header.
sha1_library	Embedded SHA-1 library error.
no_protocol_support	No support for this feature in this protocol version.
reserved_close_code	Reserved close code used.
invalid_close_code	Invalid close code used.
reason_requires_code	Using a reason requires a close code.
subprotocol_parse_error	Error parsing subprotocols.
extension_parse_error	Error parsing extensions.
extensions_disabled	Extension related operation was ignored because extensions are disabled.
short_key3	Short Ke3 read. Hybi00 requires a third key to be read from the 8 bytes after the handshake. Less than 8 bytes were read.

close::status::value websocketpp::processor::error::to_ws ( lib::error_code  ec )

inline

Converts a processor error_code into a websocket close code.

Looks up the appropriate WebSocket close code that should be sent after an error of this sort occurred.

If the error is not in the processor category close::status::blank is returned.

If the error isn't normally associated with reasons to close a connection (such as errors intended to be used internally or delivered to client applications, ex: invalid arguments) then close::status::internal_endpoint_error is returned.
