Mongodb与集群连接时节点获取错误?

我从mongodb复制了连接字符串,如下所示。

mongodb://username:<PASSWORD>@clusterstring,clusterstring1,clusterstring2/dbname?ssl=true&replicaSet=replicaSet&authSource=admin&retryWrites=true

但是当我试图用上面的字符串连接时,我得到了下面的错误。

MongoError: seed list contains no mongos proxies, replicaset connections requires the parameter replicaSet to be supplied in the URI o r options object, mongodb://server:port/db?replicaSet=name

所以上面的信息给了我两个错误

2. 要在URI或option对象中提供的复制集——我的URI中有复制集。不知道为什么会这样。

知道我做错了什么吗?

如果你想知道我在申请中是如何联系的,

this is in config

module.exports = {
    secret: 'sectreKey',
    session: { session: false },
    database: aboveconnectionstring
  }



//the above values are passed here 
module.exports = (mongoose, config) => {
    const database = mongoose.connection;
    mongoose.Promise = Promise;
    mongoose.connect(config.database, {
      promiseLibrary: global.Promise,
       useNewUrlParser: true 
    });
    database.on('error', error => console.log(`Connection to sample  service database failed: ${error}`));
    database.on('connected', () => console.log('Connected to sample  Service database'));
    database.on('disconnected', () => console.log('Disconnected from sample  Service database'));
    process.on('SIGINT', () => {
      database.close(() => {
        console.log('sampleVueService terminated, connection closed');
        process.exit(0);
      })
    });
  };

编辑:已解决

我从下面的堆栈溢出问题中找到了答案。 Mongoose cluster connection with Mongo 。但它与参数&retryWrites=true不连接。所以我删除了参数并成功连接。

所以我的新数据库连接如下

module.exports = (mongoose, config) => {
    if(config.database.indexOf('replicaSet') > - 1) {
      dbOptions = {
        db: {native_parser: true},
        replset: {
          auto_reconnect:false,
          poolSize: 10,
          socketOptions: {
            keepAlive: 1000,
            connectTimeoutMS: 30000
          }
        },
        server: {
          poolSize: 5,
          socketOptions: {
            keepAlive: 1000,
            connectTimeoutMS: 30000
          }
        }
      };
    }

    const database = mongoose.connection;
    mongoose.Promise = Promise;
    mongoose.connect(config.database, dbOptions);
    database.on('error', error => console.log(`Connection to sample  service database failed: ${error}`));
    database.on('connected', () => console.log('Connected to sample  Service database'));
    database.on('disconnected', () => console.log('Disconnected from sample  Service database'));
    process.on('SIGINT', () => {
      database.close(() => {
        console.log('sampleVueService terminated, connection closed');
        process.exit(0);
      })
    });
  };

希望它也能帮助别人。
