Question

我们使用连接到mongodb的pymongo在python脚本中编写了一段代码。

username = 'abc'
password = 'xxxxxx'
server = 'dns name of that server'
port = 27017

在程序中，代码如下：

import pymongo
from pymongo import MongoClient
client = MongoClient(url, serverSelectionTimeoutMS=300)
database = client.database_name
data_insert = database.collection_name.insert_one({'id': 1, 'name': xyz})

当我尝试执行这些操作时，会引发错误：

  File "/usr/local/lib/python2.7/dist-packages/pymongo/cursor.py", line 1114, in next

在MongoDB中，在执行查询时，我们会正常收到回复，而不会产生任何错误。

由于您的问题的其他答案对我不起作用，因此我将从a similar question复制并粘贴我的答案。

如果您尝试了上述答案，但仍然出现错误：

*This program block sets up our data set;
data episodes; 
INPUT ID_NO $ ADMIT_DATE mmddyy10. TOTAL_COST DISC_DATE mmddyy10.;
DATALINES;
1 01/01/2017 3000 01/03/2017
2 01/01/2017 14000 01/14/2017
;
run;

data new_episodes (keep= ID_NO XDATE DAILY_COST);
  set episodes;
  NUM_DAYS= DISC_DATE-ADMIT_DATE;
DAILY_COST= TOTAL_COST/(DISC_DATE-ADMIT_DATE);
*Using the Do While loop to create a matrix of date observations;
XDATE=ADMIT_DATE;*initializing our variable;
   do while(XDATE<DISC_DATE);
      put XDATE=;
      XDATE+1;
      output;*outputting the date variable;
   end;

format XDATE mmddyy10.;
run;

proc print data=new_episodes;
run;

您很有可能需要在您的uri末尾添加pymongo.errors.OperationFailure: Authentication failed.。

这是我在MongoDB服务器版本4.2.6和MongoDB Shell版本v3.6.9中使用的有效解决方案。

?authSource=admin

类似的命令行修复程序正在添加from pymongo import MongoClient # Replace these with your server details MONGO_HOST = "XX.XXX.XXX.XXX" MONGO_PORT = "27017" MONGO_DB = "database" MONGO_USER = "admin" MONGO_PASS = "pass" uri = "mongodb://{}:{}@{}:{}/{}?authSource=admin".format(MONGO_USER, MONGO_PASS, MONGO_HOST, MONGO_PORT, MONGO_DB) client = MongoClient(uri)

Answer 2

您有身份验证错误，因此首先需要

{{1}}

现在您可以尝试插入文档。

取自official mongodb documentation

Answer 3

好吧，我被大约3-4个小时的相同错误困扰。我遇到了以下步骤的解决方案：

通过输入以下内容从您的Shell连接到MongoDB：mongo

然后，创建一个数据库：use test_database

现在使用以下命令创建具有readWrite和dbAdmin特权的用户。

db.createUser(
   {
     user: "test_user",
     pwd: "testing12345",
     roles: [ "readWrite", "dbAdmin" ]
   }
);

这将提示Successfully added user: { "user" : "test_user", "roles" : [ "readWrite", "dbAdmin" ] }

您可以通过输入以下内容进行检查：show users。它还会显示您之前在json中创建的数据库名称。

现在您应该可以将数据插入数据库了

client = MongoClient("mongodb://test_user:myuser123@localhost:27017/test_database")
db = client.test_database

data = {"initial_test":"testing"}
db["my_collection"].insert_one(data).inserted_id

Answer 4

我遇到了这个错误，我的问题是密码。

我认为主帐户中有一个特殊字符。将密码更改为仅字母数字为我修复了它。

代码片段

client = pymongo.MongoClient(
        'mongodb://username:alphaNumericPassword@localhost:27017/?ssl=true&ssl_ca_certs=rds-combined-ca-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false'
    )

    # Specify the database to be used
    db = client['prod-db']

身份验证无法使用pymongo连接到mongodb
