node.js - 猫鼬无法连接到数据库

问题描述

您好，在我的 nodejs 应用程序中，我正在使用 mongo db 并尝试使用 mongoose 连接到数据库。它正在工作，即使我从未接触过连接部分，它也会突然停止。

这是用于连接的代码

    if (!process.env.MONGODB) {
      throw Error("Mongodb url is not defined.");
    }
    mongoose.set("useCreateIndex", true);
    mongoose.Promise = bluebird;
    mongoose.set("debug", false);

    await mongoose.createConnection(process.env.MONGODB, {
      useNewUrlParser: true,
      useUnifiedTopology: true,
      useFindAndModify: false,
    });
    // db = mongoose.connection;
    // db.on("connect", () => console.log("database connected"));
    // db.on("error", () => console.log("error happened!"));

    return "Succesfully Connected to the Mongodb Database at URL: "+process.env.MONGODB;
  } catch (e) {
    e.type = "initMongoDb";
    throw e;
  }//*/

这是我得到的堆栈

    "  name: 'MongoError',\n" +
    "  message: 'read ECONNRESET'\n" +
    '}]'
}

我的 IP 已列入白名单且连接字符串正确 我该怎么办？
