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：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 | from urllib.parse import quote_plusdef 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 host, \ port ) # 'mongodb://localhost:27017' # 'mongodb://xxx:27017' if isUseAuth: 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 mongodbUriif __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) |

貌似满足需求了。
