[英]How to specify multiple path patterns for a CloudFront Behavior?
I have a CloudFront distribution with an s3 origin and a custom origin.我有一个带有 s3 源和自定义源的 CloudFront 分配。 I would like all traffic on
/api/*
and /admin/*
to go to the custom origin, and all other traffic to go to the s3 origin.我希望
/api/*
和/admin/*
上的所有流量到 go 到自定义源,以及到 go 的所有其他流量到 s3 源。 Currently I have it working with only /api/*
:目前我只使用
/api/*
:
cloudfront.SourceConfiguration(
custom_origin_source=cloudfront.CustomOriginConfig(
domain_name=alb,
origin_protocol_policy=cloudfront.OriginProtocolPolicy.MATCH_VIEWER,
),
behaviors=[
cloudfront.Behavior(
allowed_methods=cloudfront.CloudFrontAllowedMethods.ALL,
path_pattern="/api/*",
forwarded_values={
"headers": ["*"],
"cookies": {"forward": "all"},
"query_string": True,
},
)
],
),
I could probably repeat the behavior with /api/*
, but I will eventually have some additional paths to add that will need to be routed to the custom origin (ALB), so I'm wondering if there is a way to do this that is more DRY.我可能会重复使用
/api/*
的行为,但我最终会添加一些额外的路径,这些路径需要路由到自定义源 (ALB),所以我想知道是否有办法做到这一点更干燥。
Does path_pattern
accept /{api,admin,other}/*
style patterns? path_pattern
是否接受/{api,admin,other}/*
样式模式? Or should I refactor the Behaviors section to reuse allowed_methods
and forwarded_values
and then repeat multiple behaviors with a different path_pattern
?或者我应该重构 Behaviors 部分以重用
allowed_methods
和forwarded_values
,然后使用不同的path_pattern
重复多个行为?
Does path_pattern accept
/{api,admin,other}/*
style patterns?path_pattern 是否接受
/{api,admin,other}/*
样式模式?
No, this pattern style is not supported based on the documentation .不,根据文档不支持这种模式样式。
should I refactor?
我应该重构吗?
Yes, you can simply save all the path_pattern
corresponding to this custom origin into a list, say path_patterns
.是的,您可以简单地将与此自定义原点对应的所有
path_pattern
保存到一个列表中,例如path_patterns
。 Then use a simple handy Python list comprehension,然后使用一个简单好用的 Python 列表推导,
behaviors=[
cloudfront.Behavior(
allowed_methods=cloudfront.CloudFrontAllowedMethods.ALL,
path_pattern=pp,
forwarded_values={
"headers": ["*"],
"cookies": {"forward": "all"},
"query_string": True,
},
) for pp in path_patterns
]
