How to handle errors with boto3?
提问by SQDK
I am trying to figure how to do proper error handling with boto3.
我试图弄清楚如何使用 boto3 进行正确的错误处理。
I am trying to create an IAM user:
我正在尝试创建一个 IAM 用户：
def create_user(username, iam_conn):
try:
user = iam_conn.create_user(UserName=username)
return user
except Exception as e:
return e
When the call to create_user succeeds, I get a neat object that contains the http status code of the API call and the data of the newly created user.
当调用 create_user 成功时，我得到一个整洁的对象，其中包含 API 调用的 http 状态代码和新创建用户的数据。
Example:
例子：
{'ResponseMetadata':
{'HTTPStatusCode': 200,
'RequestId': 'omitted'
},
u'User': {u'Arn': 'arn:aws:iam::omitted:user/omitted',
u'CreateDate': datetime.datetime(2015, 10, 11, 17, 13, 5, 882000, tzinfo=tzutc()),
u'Path': '/',
u'UserId': 'omitted',
u'UserName': 'omitted'
}
}
This works great. But when this fails (like if the user already exists), I just get an object of type botocore.exceptions.ClientError with only text to tell me what went wrong.
这很好用。但是当这失败时（比如如果用户已经存在），我只会得到一个 botocore.exceptions.ClientError 类型的对象，只有文本告诉我出了什么问题。
Example: ClientError('An error occurred (EntityAlreadyExists) when calling the CreateUser operation: User with name omitted already exists.',)
示例：ClientError('调用 CreateUser 操作时发生错误 (EntityAlreadyExists)：名称省略的用户已经存在。',)
This (AFAIK) makes error handling very hard because I can't just switch on the resulting http status code (409 for user already exists according to the AWS API docs for IAM). This makes me think that I must be doing something the wrong way. The optimal way would be for boto3 to never throw exceptions, but juts always return an object that reflects how the API call went.
这 (AFAIK) 使错误处理变得非常困难，因为我不能只打开生成的 http 状态代码（根据 IAM 的 AWS API 文档，用户的 409 已经存在）。这让我觉得我一定是在以错误的方式做某事。最佳方式是 boto3 从不抛出异常，但 juts 始终返回一个反映 API 调用方式的对象。
Can anyone enlighten me on this issue or point me in the right direction?
任何人都可以在这个问题上启发我或指出我正确的方向吗？

Use the response contained within the exception. Here is an example:
使用异常中包含的响应。下面是一个例子：
import boto3
from botocore.exceptions import ClientError
try:
iam = boto3.client('iam')
user = iam.create_user(UserName='fred')
print("Created user: %s" % user)
except ClientError as e:
if e.response['Error']['Code'] == 'EntityAlreadyExists':
print("User already exists")
else:
print("Unexpected error: %s" % e)
The response dict in the exception will contain the following:
异常中的响应字典将包含以下内容：
['Error']['Code']e.g. 'EntityAlreadyExists' or 'ValidationError'['ResponseMetadata']['HTTPStatusCode']e.g. 400['ResponseMetadata']['RequestId']e.g. 'd2b06652-88d7-11e5-99d0-812348583a35'['Error']['Message']e.g. "An error occurred (EntityAlreadyExists) ..."['Error']['Type']e.g. 'Sender'
['Error']['Code']例如“EntityAlreadyExists”或“ValidationError”['ResponseMetadata']['HTTPStatusCode']例如 400['ResponseMetadata']['RequestId']例如'd2b06652-88d7-11e5-99d0-812348583a35'['Error']['Message']例如“发生错误（EntityAlreadyExists）...”['Error']['Type']例如“发件人”

The AWS Python SDK has begun to expose service exceptions on clients(though not on resources) that you can explicitly catch, so it is now possible to write that code something like this:
AWS Python SDK 已经开始在客户端（尽管不是在资源上）公开您可以明确捕获的服务异常，因此现在可以编写如下代码：
import boto3
from botocore.exceptions import ClientError, ParamValidationError
try:
iam = boto3.client('iam')
user = iam.create_user(UserName='fred')
print("Created user: %s" % user)
except iam.exceptions.EntityAlreadyExistsException:
print("User already exists")
except ParamValidationError as e:
print("Parameter validation error: %s" % e)
except ClientError as e:
print("Unexpected error: %s" % e)
Unfortunately, there is currently no documentation for these exceptions.
不幸的是，目前没有关于这些例外的文件。

You need to do something when it fails to handle the issue. Right now you are returning the actual exception. For example, if its not a problem that the user exists already and you want to use it as a get_or_create function maybe you handle the issue by returning the existing user object.
当它无法处理问题时，您需要做一些事情。现在您正在返回实际的异常。例如，如果用户已经存在这不是问题，并且您想将其用作 get_or_create 函数，那么您可以通过返回现有用户对象来处理该问题。
try:
user = iam_conn.create_user(UserName=username)
return user
except botocore.exceptions.ClientError as e:
#this exception could actually be other things other than exists, so you want to evaluate it further in your real code.
if e.message.startswith(
'enough of the exception message to identify it as the one you want')
print('that user already exists.')
user = iam_conn.get_user(UserName=username)
return user
elif e.message.some_other_condition:
#something else
else:
#unhandled ClientError
raise(e)
except SomeOtherExceptionTypeYouCareAbout as e:
#handle it
# any unhandled exception will raise here at this point.
# if you want a general handler
except Exception as e:
#handle it.
That said, maybe it is a problem for your app, in which case you want to want to put the exception handler around the code that called your create user function and let the calling function determine how to deal with it, for example, by asking the user to input another username, or whatever makes sense for your application.
也就是说，这可能是您的应用程序的问题，在这种情况下，您希望将异常处理程序放在调用您的创建用户函数的代码周围，并让调用函数确定如何处理它，例如，通过询问用户输入另一个用户名，或任何对您的应用程序有意义的用户名。

Or a comparison on the class name e.g.
或者类名的比较，例如
except ClientError as e:
if 'EntityAlreadyExistsException' == e.__class__.__name__:
# handle specific error
Because they are dynamically created you can never import the class and catch it using real Python.
因为它们是动态创建的，所以您永远无法导入该类并使用真正的 Python 捕获它。

Just an update to the 'no exceptions on resources' problem as pointed to by @jarmod (do please feel free to update your answer if below seems applicable)
只是对@jarmod 指出的“资源无例外”问题的更新（如果以下似乎适用，请随时更新您的答案）
I have tested the below code and it runs fine. It uses 'resources' for doingthings, but catches the client.exceptions- although it 'looks' somewhat wrong... it tests good, the exception classes are showing and matching when looked into using debugger at exception time...
我已经测试了下面的代码，它运行良好。它采用“资源”为做的事情，但抓住了client.exceptions-当看着在异常时使用调试器，虽然它看起来“有点错......它测试好，异常类都出现了和匹配...
It may not be applicable to all resources and clients, but works for data folders (aka s3 buckets).
它可能不适用于所有资源和客户端，但适用于数据文件夹（又名 s3 存储桶）。
lab_session = boto3.Session()
c = lab_session.client('s3') #this client is only for exception catching
try:
b = s3.Bucket(bucket)
b.delete()
except c.exceptions.NoSuchBucket as e:
#ignoring no such bucket exceptions
logger.debug("Failed deleting bucket. Continuing. {}".format(e))
except Exception as e:
#logging all the others as warning
logger.warning("Failed deleting bucket. Continuing. {}".format(e))
Hope this helps...
希望这可以帮助...

I found it very useful, since the Exceptions are not documented, to list all exceptions to the screen for this package. Here is the code I used to do it:
我发现它非常有用，因为没有记录异常，列出这个包的屏幕的所有异常。这是我用来做的代码：
import botocore.exceptions
def listexns(mod):
#module = __import__(mod)
exns = []
for name in botocore.exceptions.__dict__:
if (isinstance(botocore.exceptions.__dict__[name], Exception) or
name.endswith('Error')):
exns.append(name)
for name in exns:
print('%s.%s is an exception type' % (str(mod), name))
return
if __name__ == '__main__':
import sys
if len(sys.argv) <= 1:
print('Give me a module name on the $PYTHONPATH!')
print('Looking for exception types in module: %s' % sys.argv[1])
listexns(sys.argv[1])
Which results in:
结果是：
Looking for exception types in module: boto3

If you are calling the sign_up API (AWS Cognito) using Python3, you can use the following code.
如果您使用 Python3 调用 sign_up API (AWS Cognito)，则可以使用以下代码。
def registerUser(userObj):
''' Registers the user to AWS Cognito.
'''
# Mobile number is not a mandatory field.
if(len(userObj['user_mob_no']) == 0):
mobilenumber = ''
else:
mobilenumber = userObj['user_country_code']+userObj['user_mob_no']
secretKey = bytes(settings.SOCIAL_AUTH_COGNITO_SECRET, 'latin-1')
clientId = settings.SOCIAL_AUTH_COGNITO_KEY
digest = hmac.new(secretKey,
msg=(userObj['user_name'] + clientId).encode('utf-8'),
digestmod=hashlib.sha256
).digest()
signature = base64.b64encode(digest).decode()
client = boto3.client('cognito-idp', region_name='eu-west-1' )
try:
response = client.sign_up(
ClientId=clientId,
Username=userObj['user_name'],
Password=userObj['password1'],
SecretHash=signature,
UserAttributes=[
{
'Name': 'given_name',
'Value': userObj['given_name']
},
{
'Name': 'family_name',
'Value': userObj['family_name']
},
{
'Name': 'email',
'Value': userObj['user_email']
},
{
'Name': 'phone_number',
'Value': mobilenumber
}
],
ValidationData=[
{
'Name': 'email',
'Value': userObj['user_email']
},
]
,
AnalyticsMetadata={
'AnalyticsEndpointId': 'string'
},
UserContextData={
'EncodedData': 'string'
}
)
except ClientError as error:
return {"errorcode": error.response['Error']['Code'],
"errormessage" : error.response['Error']['Message'] }
except Exception as e:
return {"errorcode": "Something went wrong. Try later or contact the admin" }
return {"success": "User registered successfully. "}
error.response['Error']['Code'] will be InvalidPasswordException, UsernameExistsException etc. So in the main function or where you are calling the function, you can write the logic to provide a meaningful message to the user.
error.response['Error']['Code'] 将是 InvalidPasswordException、UsernameExistsException 等。因此，在主函数或调用函数的地方，您可以编写逻辑以向用户提供有意义的消息。
An example for the response (error.response):
响应示例（error.response）：
{
"Error": {
"Message": "Password did not conform with policy: Password must have symbol characters",
"Code": "InvalidPasswordException"
},
"ResponseMetadata": {
"RequestId": "c8a591d5-8c51-4af9-8fad-b38b270c3ca2",

Following @armod's update about exceptions being added right on clientobjects. I'll show how you can see all exceptions defined for your client class.
遵循@armod 关于在client对象上添加异常的更新。我将展示如何查看为客户端类定义的所有异常。
Exceptions are generated dynamically when you create your client with session.create_client()or boto3.client(). Internally it calls method botocore.errorfactory.ClientExceptionsFactory._create_client_exceptions()and fills client.exceptionsfield with constructed exception classes.
使用session.create_client()或 来创建客户端时会动态生成异常boto3.client()。它在内部调用方法botocore.errorfactory.ClientExceptionsFactory._create_client_exceptions()并client.exceptions用构造的异常类填充字段。
All class names are available in client.exceptions._code_to_exceptiondictionary, so you can list all types with following snippet:
所有类名都在client.exceptions._code_to_exception字典中可用，因此您可以使用以下代码段列出所有类型：
client = boto3.client('s3')
for ex_code in client.exceptions._code_to_exception:
print(ex_code)
Hope it helps.
希望能帮助到你。

As a few others already mentioned, you can catch certain errors using the service client (service_client.exceptions.<ExceptionClass>) or resource (service_resource.meta.client.exceptions.<ExceptionClass>), however it is not well documented (also which exceptions belong to which clients). So here is how to get the complete mapping at time of writing (January 2020) in region EU (Ireland) (eu-west-1):
正如其他一些人已经提到的，您可以使用服务客户端 ( service_client.exceptions.<ExceptionClass>) 或资源 ( service_resource.meta.client.exceptions.<ExceptionClass>)捕获某些错误，但是没有很好的文档记录（以及哪些异常属于哪些客户端）。因此，以下是如何在撰写本文时（2020 年 1 月）在欧盟（爱尔兰）地区 ( ) 获取完整映射eu-west-1：
import boto3, pprint
region_name = 'eu-west-1'
session = boto3.Session(region_name=region_name)
exceptions = {
service: list(boto3.client('sts').exceptions._code_to_exception)
for service in session.get_available_services()
}
pprint.pprint(exceptions, width=20000)

回答by Alexander Fortin
In case you have to deal with the arguably unfriendly logsclient (CloudWatch Logs put-log-events), this is what I had to do to properly catch Boto3 client exceptions:
如果您必须处理可以说是不友好的logs客户端 ( CloudWatch Logsput-log-events)，这就是我必须做的才能正确捕获 Boto3 客户端异常：
try:
### Boto3 client code here...
except boto_exceptions.ClientError as error:
Log.warning("Catched client error code %s",
error.response['Error']['Code'])
if error.response['Error']['Code'] in ["DataAlreadyAcceptedException",
"InvalidSequenceTokenException"]:
Log.debug(
"Fetching sequence_token from boto error response['Error']['Message'] %s",
error.response["Error"]["Message"])
# NOTE: apparently there's no sequenceToken attribute in the response so we have
# to parse response["Error"]["Message"] string
sequence_token = error.response["Error"]["Message"].split(":")[-1].strip(" ")
Log.debug("Setting sequence_token to %s", sequence_token)
This works both at first attempt (with empty LogStream) and subsequent ones.
这在第一次尝试（使用空 LogStream）和后续尝试时都有效。
