Question

我试图删除所有堆栈，这些环境（实例）已终止。在将stack_name传递给delete_stack时，它会抛出一个错误。我试图将特殊字符（例如＆＃39;＆＃39;）添加到stack_name的值，但没有运气。有人可以帮我解决这个问题。提前谢谢！

#!/usr/bin/env python

import boto
import boto.ec2
import boto.cloudformation
import re
from datetime import datetime, timedelta

utclast = datetime.utcnow() - timedelta(2)

conn = boto.cloudformation.connect_to_region('us-west-1',aws_access_key_id = '<access_key>',aws_secret_access_key = '<secret_key>')
conn_ec2 = boto.ec2.connect_to_region('us-west-1',aws_access_key_id = '<access_key>',aws_secret_access_key = '<secret_key>')

stacks = conn.list_stacks()
for stackSumm in stacks:
    pattern = re.compile("Testupload-env([a-zA-Z0-9]+)")
    match = pattern.match(stackSumm.stack_name)
    if stackSumm.stack_status in "CREATE_COMPLETE" and match and stackSumm.stack_name in match.string:
        m = re.split(r'Testupload-', stackSumm.stack_name)
        instance = conn_ec2.get_all_instances(filters={"tag:Name": m[1]})
        if not instance:

            try:
                    print "Trying to delete stack: %s" % stackSumm.stack_name
                    conn.delete_stack(stackSumm.stack_name)

            except boto.exception.BotoServerError, e:
                    print e.error_message

错误：

File "delete_stack.py", line 7, in <module>
    conn.delete_stack(Testupload-envmeraleb8b01739116b0f36d17a2b5445b949f592bb625-6293)
NameError: name 'Testupload' is not defined

你们都没有发布代码生成错误，但是NameError说你没有提供有效的堆栈名称

delete_stack（stack_name_or_id）   删除指定的堆栈。呼叫成功完成后，将开始堆栈删除。如果删除已成功完成，则已删除的堆栈不会显示在DescribeStacks API中。

参数：stack_name_or_id（string） - 与堆栈关联的名称或唯一标识符。

名称/ id应该是一个字符串，python中的字符串必须用单引号或双引号引用

stack_name = "Testupload-envmeraleb8b01739116b0f36d17a2b5445b949f592bb625-6293"
conn.delete_stack(stack_name)

将特殊字符附加到python中的值
