捕捉異常：錯誤：升級後在結束後寫入節點版本

Question

我的Node.js應用程序在節點v10.29下運行正常。

，當「節點」的版本。

我升級的節點到12.0版本後，我開始一個Caught exception: Error: write after end錯誤：

Caught exception: Error: write after end at ServerResponse.OutgoingMessage.write (_http_outgoing.js:413:15) at ServerResponse.res.write (/home/node_app_name/node_modules/express/node_modules/connect/lib/middleware/compress.js:110:17) at ServerResponse.res.end (/home/node_app_name/node_modules/express/node_modules/connect/lib/middleware/compress.js:116:14) at ServerResponse.res.send (/home/node_app_name/node_modules/express/lib/response.js:152:8) at /home/node_app_name/models/file_name.js:1205:61 at /home/node_app_name/node_modules/mongoose/lib/utils.js:414:16 at /home/node_app_name/node_modules/mongoose/node_modules/mongodb/lib/mongodb/collection.js:497:9 at Server.Base._callHandler (/home/node_app_name/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/base.js:382:41) at /home/node_app_name/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/server.js:472:18 at MongoReply.parseBody (/home/node_app_name/node_modules/mongoose/node_modules/mongodb/lib/mongodb/responses/mongo_reply.js:68:5)

我尋覓了很多關於上述錯誤，但我仍然不能夠得到有效的解決方案吧。

什麼是導致此錯誤，我該如何解決它？

Answer 1

如果您正在使用res.send（...）; （在路徑代碼app.get（'path'，function（req，res）{}）;）中的代碼中不止一次。將其改爲res.write（....）;

Answer 2

我想你應該把response.end（）;在聲明路徑的每一端（「/」或「/ etc」）中。
