Conns connecting back to the original dialer, which then gets a net. Listener accepting those conns. The motivation is that sometimes you want to run a server on a machine deep inside a NAT. Rather than connecting to the machine directly which you can't, because of the NATyou have the sequestered machine connect out to a public machine.

Both sides then use revdial and the public machine can become a client for the NATed machine. A dialer to connect to it is given to NewListener and the path to reach it is given to NewDialer to use in messages to the listener.

NewDialer returns the side of the connection which will initiate new connections. The connection is typically the hijacked HTTP client connection. Done returns a channel which is closed when d is closed either by this process on purpose, by a local error, or close or error from the peer.

NewListener returns a new Listener, accepting connections which arrive from the provided server connection, which should be after any necessary authentication usually after an HTTP exchange.

The provided dialServer func is responsible for connecting back to the server and doing TLS setup. Toggle navigation GoDoc.

The configuration config must be non-nil and must include at least one certificate or else set GetCertificate. NewListener creates a Listener which accepts connections from an inner Listener and wraps each connection with Server.

The files must contain PEM encoded data. The certificate file may contain intermediate certificates following the leaf certificate to form a certificate chain. On successful return, Certificate. Leaf will be nil because the parsed form of the certificate is not retained. CertificateRequestInfo contains information from a server's CertificateRequest message, which is used to demand a certificate and proof of control from a client. SupportsCertificate returns nil if the provided certificate is supported by the server that sent the CertificateRequest.

Otherwise, it returns an error describing the reason for the incompatibility. CipherSuite is a TLS cipher suite. Note that most functions in this package accept and expose cipher suite IDs instead of this type.

CipherSuites returns a list of cipher suites currently implemented by this package, excluding those with security issues, which are returned by InsecureCipherSuites. The list is sorted by ID. Note that the default cipher suites selected by this package might depend on logic that can't be captured by a static list. InsecureCipherSuites returns a list of cipher suites currently implemented by this package and which have security issues. Most applications should not use the cipher suites in this list, and should only use those returned by CipherSuites.

SupportsCertificate returns nil if the provided certificate is supported by the client that sent the ClientHello. Note that if GetConfigForClient returns a different Config, the change can't be accounted for by this method.Toggle navigation Hot Examples. Golang Dialer.

It avoids redundant allocations and copying of not used headers or other request data. User decides by himself which data should be copied. After WebSocket handshake you can work with connection in multiple ways.

Status code ranges defined by specification. ErrHandshakeUpgradeRequired is returned by Upgrader to indicate that connection is rejected because given WebSocket version is malformed.

ErrNotHijacker is an error returned when http. ResponseWriter does not implement http. Hijacker interface. If endpoint sends close frame without status code with frame. Note that zero state 0 means that state is clean, neither server or client side, nor fragmented, nor extended.

Cipher applies XOR cipher to the payload using mask. Offset is used to cipher chunked data e. Reader implementations. To convert masked data into unmasked data, or vice versa, the following algorithm is applied.

The same algorithm applies regardless of the direction of the translation, e. CompileFrame returns byte representation of given frame. In terms of memory consumption it is useful to precompile static frames which are often used. HeaderSize returns number of bytes that are needed to encode given header.

It returns -1 if header is malformed.

If the reason is too big it will be cropped to fit the limit defined by the spec. PutReader returns bufio. Reader instance to the inner reuse pool. It is useful in rare cases, when Dialer. Dial returns non-nil buffer which contains unprocessed buffered data, that was sent by the server quickly right after handshake. RejectConnectionError constructs an error that could be used to control the way handshake is rejected by Upgrader. If server has sent frames right after successful handshake then returned buffer will be non-nil.

In other cases buffer is always nil. For better memory efficiency received non-nil bufio. Reader should be returned to the inner pool with PutReader function after use. If you want to dial non-ascii host name, take care of its name serialization avoiding bad request issues.

Write implementation, especially cleanHost function. Upgrade writes an upgrade request to the given io.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
