尝试在Fn :: FindInMap中使用Fn :: Join，如下所示：

"SubnetId": {
    "Fn::FindInMap": [
        {
            "Ref": "OrganizationName"
        },
        "AZ",
        {
            "Fn::Join": [
                "",
                [
                    {
                        "Ref": "Environment"
                    },
                    {
                        "Ref": "Member1AZ"
                    }
                ]
            ]
        }
    ]
}

OrganizationName，Environment和Member1AZ都是参数。本质上，它应该连接到我的映射并生成，例如：

"SubnetId" : { "Fn::FindInMap" : [ "Organization2", "AZ", "prod1c" ]}

但是，它似乎没有将Fn :: Join的输出作为Fn :: FindInMap上的单个实体使用，如果我对模板的该部分进行硬编码，它将正确验证。

A client error (ValidationError) occurred when calling the ValidateTemplate operation: Template error: every Fn::FindInMap object requires three parameters, the map name, map key and the attribute for return value

我的映射如下：

Mappings" : …

尝试使用自定义SSL协商策略设置云信息模板.我得到的cloudformation错误是:

无法启用CREATE_FAILED AWS :: ElasticLoadBalancing :: LoadBalancer BackendELB SSLNegotiationPolicy

我的cloudformation模板部分如下:

"Policies" : [
                {
                    "PolicyName": "SSLNegotiationPolicy",
                    "PolicyType": "SSLNegotiationPolicyType",
                    "Attributes": [
                        { "Name" : "Protocol-TLSv1", "Value" : "true" },
                        { "Name" : "Protocol-TLSv1.1", "Value" : "true" },
                        { "Name" : "Protocol-TLSv1.2", "Value" : "true" },
                        { "Name" : "Protocol-SSLv2", "Value" : "false" },
                        { "Name" : "Protocol-SSLv3", "Value" : "false" },
                        { "Name" : "ECDHE-RSA-AES128-GCM-SHA256", "Value" : "true" },
                        { "Name" : "ECDHE-ECDSA-AES128-SHA256", "Value" : "true" },
                        { "Name" : "ECDHE-RSA-AES128-SHA256", …
