Root Cause
Server closed WebSocket connection due to a policy violation such as invalid authentication, unsupported subprotocol, or message format violation.
generic中文
服务器因策略违规关闭WebSocket连接,例如无效身份验证、不支持的子协议或消息格式违规。
Official Documentation
https://datatracker.ietf.org/doc/html/rfc6455#section-7.4.1Workarounds
-
90% success Check and refresh authentication token before reconnecting: `ws = new WebSocket('wss://api.example.com/ws', { headers: { Authorization: `Bearer ${newToken}` } })`
Check and refresh authentication token before reconnecting: `ws = new WebSocket('wss://api.example.com/ws', { headers: { Authorization: `Bearer ${newToken}` } })` -
80% success Verify the subprotocol matches server expectations: `ws = new WebSocket('wss://api.example.com/ws', ['graphql-ws'])`
Verify the subprotocol matches server expectations: `ws = new WebSocket('wss://api.example.com/ws', ['graphql-ws'])` -
85% success Ensure messages are in the expected format (e.g., JSON): `ws.send(JSON.stringify({ type: 'subscribe', channel: 'updates' }))`
Ensure messages are in the expected format (e.g., JSON): `ws.send(JSON.stringify({ type: 'subscribe', channel: 'updates' }))`
中文步骤
重新连接前检查并刷新身份验证令牌:`ws = new WebSocket('wss://api.example.com/ws', { headers: { Authorization: `Bearer ${newToken}` } })`验证子协议是否与服务器期望匹配:`ws = new WebSocket('wss://api.example.com/ws', ['graphql-ws'])`确保消息格式符合预期(例如JSON):`ws.send(JSON.stringify({ type: 'subscribe', channel: 'updates' }))`
Dead Ends
Common approaches that don't work:
-
85% fail
Reconnecting without addressing the underlying policy violation (e.g., expired token)
-
60% fail
Assuming it's a network timeout and increasing timeout values
-
70% fail
Changing WebSocket URL path without verifying authentication credentials
