Amazon web services 如何使用terraform在AWS上启用CORS

我正在尝试在aws项目上启用CORS，该项目由

API网关

和

Lambda

函数组成。 我正在使用

GET

和

OPTIONS

方法创建一个API网关。

选项

是根据aws启用CORS的模拟端点。 有一个lambda函数（

aws\u lambda\u function.app\u lambda

），由

GET

方法调用，响应头中有：

"Access-Control-Allow-Origin": "*",
"Access-Control-Allow-Headers": "Content-Type",
"Access-Control-Allow-Methods": "OPTIONS,POST,GET"

但我还是不能通过CORS考试

任何帮助都会被告知。

找到了一个简单的解决方案。问题是，在对现有API网关应用更新的更改时，没有重新部署这些网关。因此，我不得不自己手动重新部署它们，并考虑如何在terraform中实现这一点。

您可以使用terraform模块启用cors：

module "api-gateway-enable-cors" {
source  = "squidfunk/api-gateway-enable-cors/aws"
version = "0.3.1"
api_id          = "<your_api_id>"
api_resource_id = "<your_api_resource_id>"
}

模块“api网关启用cors”{
source=“squidfunk/api网关启用cors/aws”
version=“0.3.1”
api_id=“”
api_资源_id=“”
}
