折腾：
【未解决】PySpider中把结果保存到MongoDB数据库中
期间，涉及到本地开发测试和在线生产等不同环境，传递不同参数给pymongo的MongoClient，去打开和连接MongoDB。
而关于mongodb的uri，此处希望可以根据参数不同自动生成。
参考之前用过的代码，另外再去整合
先参考：
经过调试，目前用代码：
from urllib.parse import quote_plus
def generateMongoUri(host=None,
port=None,
isUseAuth=False,
username=None,
password=None,
authSource=None,
authMechanism=None):
""""generate mongodb uri"""
mongodbUri = ""
if not host:
# host = "127.0.0.0"
host = "localhost"
if not port:
port = 27017
mongodbUri = "mongodb://%s:%s" % (
host, \
port
)
# '
mongodb://localhost:27017
'
# '
mongodb://xxx:27017
'
if isUseAuth:
mongodbUri = "mongodb://%s:%s@%s:%s" % (
quote_plus(username), \
quote_plus(password), \
host, \
port \
)
print(mongodbUri)
if authSource:
mongodbUri = mongodbUri + ("/%s" % authSource)
print("mongodbUri=%s" % mongodbUri)
if authMechanism:
mongodbUri = mongodbUri + ("?authMechanism=%s" % authMechanism)
print("mongodbUri=%s" % mongodbUri)
print("return mongodbUri=%s" % mongodbUri)
#
mongodb://username:quoted_password@host:port/authSource?authMechanism=authMechanism
#
mongodb://localhost:27017
return mongodbUri
if __name__ == "__main__":
# test default
defaultMongoUri = generateMongoUri()
print("defaultMongoUri=%s" % defaultMongoUri)
# test normal host port
normalMongoUri = generateMongoUri(host="1.2.3.4", port=34567)
print("normalMongoUri=%s" % normalMongoUri)
# test use auth
useAuthMongoUri = generateMongoUri(host="1.2.3.4",
port=34567,
isUseAuth=True,
username="normal_user",
password="complexP@D",
authSource="admin",
authMechanism="SCRAM-SHA-1")
print("useAuthMongoUri=%s" % useAuthMongoUri)输出：
return mongodbUri= mongodb://localhost:27017 defaultMongoUri= mongodb://localhost:27017 return mongodbUri= mongodb://1.2.3.4:34567 normalMongoUri= mongodb://1.2.3.4:34567 mongodb://normal_user:complexP%[email protected]:34567 mongodbUri= mongodb://normal_user:complexP%[email protected]:34567/admin mongodbUri= mongodb://normal_user:complexP%[email protected]:34567/admin?authMechanism=SCRAM-SHA-1 return mongodbUri= mongodb://normal_user:complexP%[email protected]:34567/admin?authMechanism=SCRAM-SHA-1 useAuthMongoUri= mongodb://normal_user:complexP%[email protected]:34567/admin?authMechanism=SCRAM-SHA-1 [1] 4243 terminated env "PYTHONIOENCODING=UTF-8" "PYTHONUNBUFFERED=1" /usr/local/bin/python3
貌似满足需求了。
