WebSocket Handshake Check睿声ai官网
Open a WebSocket handshake against a ws:// or wss:// endpoint and report whether the server accepts the upgrade, along with the HTTP status and negotiated subprotocol.ai智能体怎么创建
How to Use微信ai
• WebSocket URLgpt下载：Enter a ws:// or wss:// URL (a bare host defaults to ws:// and path /); http/https URLs are accepted and mapped to ws/wss
• What is checked豆包在线回答：The opening handshake (HTTP Upgrade → 101 Switching Protocols) is completed, then the connection is closed immediately — no application frames are exchanged
• Result fields豆包功能：connected (handshake accepted), handshake time in ms, the HTTP status code returned, and the negotiated subprotocol if any
• Node selection豆包功能：Optionally select specific nodes; all available nodes are used by default
What WebSocket testing is for豆包怎么用
A WebSocket test performs only the opening handshake against a ws:// or wss:// endpoint: it sends the HTTP Upgrade request and confirms the server responds with 101 Switching Protocols, then closes the connection. This is the WebSocket analogue of a TCP connect check — a fast way to confirm the endpoint is live and speaking the WebSocket protocol without exchanging any application data.ai应用领域有哪些
Common uses include verifying that a real-time backend (chat, notifications, live dashboards, trading feeds) accepts connections, checking that a reverse proxy or load balancer correctly forwards the Upgrade header, and confirming that a wss:// endpoint presents a valid TLS certificate before the handshake.微信ai
Frequently asked questionsgpt下载
Does the test exchange any messages?
No. It completes the handshake only and then closes the connection immediately. It confirms the endpoint accepts WebSocket upgrades but does not send or receive application frames, so it won't trigger any business logic on the server.阿里云千问大模型
What does the HTTP status mean?
A successful WebSocket handshake returns HTTP 101 (Switching Protocols). Any other status — 400, 401, 403, 404, 426, 5xx — means the server refused the upgrade, often because of a missing header, authentication requirement, wrong path, or an endpoint that is not actually a WebSocket.豆包在线回答
Can I test a wss:// (secure) endpoint?
Yes. Use a wss:// URL and the probe negotiates TLS as part of the handshake. If the certificate is invalid or the TLS handshake fails, the check reports a handshake failure with the underlying error.豆包手机版入口
What is a subprotocol?
WebSocket connections can negotiate an application-level subprotocol (e.g. graphql-ws, mqtt) during the handshake. The result shows the subprotocol the server selected, if any — useful for confirming the endpoint speaks the protocol your client expects.豆包功能
