报错全文

pymongo.errors.ServerSelectionTimeoutError: Could not reach any servers in [('localhost', 27017)]. Replica set is configured with internal hostnames or IPs?, Timeout: 30s, Topology Description: <TopologyDescription id: 6673d766f36938e3f8b3bc51, topology_type: ReplicaSetNoPrimary, servers: [<ServerDescription ('localhost', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('localhost:27017: [WinError 10061] 由于目标计算机积极拒绝，无法连接。')>]>

已经配置了ip，还显示localhostxxx，网上说是因为MongoClient默认HOST是localhost

这个其实不重要，参考google上搜到的，然后自己测试，得出解决办法

myclient = pymongo.MongoClient("mongodb://root:xxx@192.168.30.xxx:27017/?directConnection=true")
mydb = myclient["xxx"]
mycol = mydb["xxx"]

重点是directConnection=true，不太理解，反正解决了
