Fetch 报错 常规 排查 SocketError other side closed 在 main.js 中使用了 fetch,但是在运行 main.js 的时候时候 fetch 报错。 % node main.js (node:51258) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification. (Use `node --trace-warnings ...` to show where the warning was created) node:internal/deps/undici/undici:11730 Error.captureStackTrace(err, this); ^ TypeError: fetch failed at Object.fetch (node:internal/deps/undici/undici:11730:11) at async getFansNum (/Users/kazoottt/GitHub/bilibili-fans/main.js:11:20) { cause: SocketError: other side closed at TLSSocket.onSocketEnd (node:internal/deps/undici/undici:8280:26) at TLSSocket.emit (node:events:526:35) at endReadableNT (node:internal/streams/readable:1589:12) at process.processTicksAndRejections (node:internal/process/task_queues:82:21) { code: 'UND_ERR_SOCKET', socket: { localAddress: '198.19.0.1', localPort: 55306, remoteAddress: '198.18.2.185', remotePort: 443, remoteFamily: 'IPv4', timeout: undefined, bytesWritten: 607, bytesRead: 0 } } } Node.js v20.10.0 从报错信息中可以看出来是 getFansNum 这个方法中的 fetch 方法报了错。 解决方法: 关闭 MitM
