The reason is Subscribe needs topicfilter Resource and not topic原因是 Subscribe 需要topicfilter资源而不是 topic
Here's an Example:这是一个例子:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"iot:Connect"
],
"Resource": [
"*"
]
},
{
"Effect": "Allow",
"Action": [
"iot:Publish",
"iot:Receive"
],
"Resource": [
"arn:aws:iot:us-east-1:xxx:topic/$aws/certificates/create/*",
"arn:aws:iot:us-east-1:xxx:topic/$aws/provisioning-templates/test/provision/*"
]
},
{
"Effect": "Allow",
"Action": [
"iot:Subscribe"
],
"Resource": [
"arn:aws:iot:us-east-1:xxx:topicfilter/$aws/certificates/create/*",
"arn:aws:iot:us-east-1:xxx:topicfilter/$aws/provisioning-templates/test/provision/*"
]
}
]
}
