The WebSocket protocol. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source. WebSockets are often used for chat-based apps and other apps that need to continuously talk between server and client. Although the text opcode, 0x01, is the most commonly used value, the websocket-client library makes it possible to customize which opcode is used. The WebSocket Protocol enables two-way communication between a client running untrusted code in a controlled environment to a remote host that has opted-in to communications from that code. WebSocket is designed to be implemented in web browsers and web servers, but it can be used by any client or server application. The code We will start our code by importing the websocket module, which will expose the functionality we need to connect to the server. WebSockets 是一个托管在 GitHub 上的基于. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

Object com. Websocket principle (handshake, decryption, encryption) The WebSocket protocol is a new protocol based on TCP. 14+ Mac Catalyst 13. so that a single port can be used by both HTTP clients talking to that server and WebSocket clients talking to that server. Detailed Description Constants and utility functions related to WebSocket opcodes. Kết nối WebSocket được khởi tạo bằng việc nâng cấp từ giao thức HTTP sang giao thức WebSocket trong quá trình handshake giữa client và server thông qua cùng một kết nối TCP. The opcode is an integer number. The WebSocket Protocol WebSocket is a framed protocol, meaning that a chunk of data (a message) is divided into a number of discrete chunks, with the size of the chunk encoded in the frame. To view the data it must first be decrypted and then unmasked. Essentially, the WebSocket API is an advanced technology that makes it possible to open up a two-way interactive communication session between your user's browser and your server. The MASK bit, payload length and masking-key are handled on the fly when parsing and serializing frames. Protocol namespace. Unlike HTTP, which uses a request and response pattern, WebSocket peers can send messages in either direction at any point in time. decode("utf-8") if PY3 else data Example #2 Source Project: python-base Author: kubernetes-client File: ws_client. 16 трав.

WebSocket 有什么优点 开销少、时时性高、二进制支持完善、支持扩展、压缩更优。 较少的控制开销。 在连接创建后，服务器和客户端之间交换数据时，用于协议控制的数据包头部相对较小。 在不包含扩展的情况下，对于服务器到客户端的内容，此头部大小只有2至10字节（和数据包长度有关）；对于客户端到服务器的内容，此头部还需要加上额外的4字节的掩码。 相对于HTTP请求每次都要携带完整的头部，此项开销显著减少了。 更强的实时性。 由于协议是全双工的，所以服务器可以随时主动给客户端下发数据。 相对于HTTP请求需要等待客户端发起请求服务端才能响应，延迟明显更少；即使是和Comet等类似的长轮询比较，其也能在短时间内更多次地传递数据。 保持连接状态。. This means that you don't have to bloat your server code with cookie and authentication handlers (for example). Note: It is a good idea to include the namespace with the using keyword in order to write less. 我们知道，http 是一问一答的模式，客户端向服务器发送 http 请求，服务器返回 http 响应。这种模式对资源、数据的加载足够用，但是需要数据推送的场景就不合适了。有同学说，http2 不是有 server push 么？那只是推资源用的：比如浏览器请求了 html，服务端可以连带把 css 一起推送给浏览器。浏.
