PyMongo 身份验证失败：{'ok'：0.0，'errmsg'：'身份验证失败。'，'code'：18，'codeName'：'AuthenticationFailed'

Question

奇怪的是，我在 Docker 容器中运行 SLS Python Lambda，而 MongoDB 实例在单独的容器中。我能够从主机上的公开端口进行身份验证以连接到实例。

但是，从 SLS 容器内部出于某种原因它不想连接：S

# mongodb://root:password@mongodb/test_db?retryWrites=true&w=majority
db_uri = "mongodb://" + usr + ":" + pwd + "@" + url + "/test_db?retryWrites=true&w=majority"
client = pymongo.MongoClient(db_uri)

db = client[mongo_db_name]
collection = db[mongo_collection_name]

version: "3.8"
services:
  mongodb:
    image : mongo
    environment:
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=password
      - MONGO_INITDB_DATABASE=test_db
      - PUID=1000
      - PGID=1000
    ports: 
      - "27000:27017"
    restart: unless-stopped
    volumes:
      - ./mongodb/init.js:/docker-entrypoint.initdb.d/init.js

  python:
    build: python
    depends_on:
      - mongodb
    ports: 
      - "3000:3000"
    restart: unless-stopped
    volumes:
      - ./python:/usr/src/app

Answer 1

需要添加 authSource ( https://pymongo.readthedocs.io/en/stable/examples/authentication.html#default-database-and-authsource )

db_uri = "mongodb://" + usr + ":" + pwd + "@" + \
    url + "/test_db?authSource=admin&retryWrites=true&w=majority"
