node.js - 如何从nodejs请求捕获像MaxListenersExceededWarning这样的错误？

Question

例如，以下错误不会被请求的常规 try/catch 捕获:

(node:6432) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 pipe listeners added. Use emitter.setMaxListeners() to increase limit
Error: Exceeded maxRedirects. Probably stuck in a redirect loop https://9.20.65.117/
    at Redirect.onResponse (/XXX/node_modules/request/lib/redirect.js:98:27)
    at Request.onRequestResponse (/XXX/node_modules/request/request.js:990:22)
    at emitOne (events.js:115:13)
    at ClientRequest.emit (events.js:210:7)
    at HTTPParser.parserOnIncomingClient [as onIncoming] (_http_client.js:565:21)
    at HTTPParser.parserOnHeadersComplete (_http_common.js:116:23)
    at TLSSocket.socketOnData (_http_client.js:454:20)
    at emitOne (events.js:115:13)
    at TLSSocket.emit (events.js:210:7)
    at addChunk (_stream_readable.js:266:12)

Answer 1

您可以简单地在请求选项对象中禁用遵循 3xx 重定向请求({followRedirect: false}, ...)

或者将 Nodejs process.setMaxListeners(0); 更改为 0(无限制)
