What is a JWT?The full name of the JWT is the JSON Web Token, a concise, URL-safe declarative specification for communicating security information between the two parties. JWT, as an open standard (RFC 7519), defines a concise, self-contained method for communicating information between two communication parties in the form of a JSON object. Because of the presence of digital signatures, this information is trustworthy, and JWT can be signed using the HMAC algorithm or the public-private key pai

: boolean; isOperationSuccess: boolean; isEditing: boolean;}At this time, we need to remember in mind, never to modify the model field! MessageThe Message is used to define the events that the application may trigger during the run, for example, in a stopwatch application, we define three events such as "Start Time", "Pause Timer", "Reset". In ELM, you can use the union type to define message, and if you use TypeScript, you can define multiple message classes and then create a union type d

rolling back, which uses a transport connection to transmit requests and responses at the same time (for example, transfer requests and responses over an HTTP connection). In transport-level asynchrony, different transport connections are used to send requests and receive responses individually, such as when using SMTP for transport.

header sent by my browser: After receiving the handshake request, the server extracts the "Sec-WebSocket-Key" field in the Request Header, recovers a fixed string '258eafa5-E914-47DA-95CA-C5AB0DC85B11 ', and then performs sha1 encryption, finally, it is converted to base64 encoding. The key is returned to the client using the "Sec-WebSocket-Accept" field. After the client matches the key, the connection is established and the handshake is completed;Data Transmission Websocket has its own defin

restructure the packet sequence of the sender, and the serial number can also be used to determine the appropriate packet location. For example, in video decoding, sequential decoding is not required. The RTP protocol consists of two closely linked parts: RTP: transfers data with real-time attributes; RTP Control Protocol (RTCP)-monitors service quality and transmits information about ongoing session participants. The second feature of RTCP is sufficient for "loose controlled" sessions, that is
