如果您使用HTTP解析器，AppSync还可以代表您计算Api网关所需的sigv4签名

无法通过控制台对HTTP数据源进行配置更改，但可以使用AWS CLI传递以下参数：

aws appsync update-data-source --api-id yojcj4cdzzhizkscqocnr5xhem --name ApiGatewayTest --type HTTP --service-role-arn arn:aws:iam::769682826941:role/ApiGatewayRole --http-config file:///home/yourdir/apigateway.json

    "authorizationConfig": {
       "authorizationType": "AWS_IAM",
       "awsIamConfig": {
         "signingRegion": "us-east-1",
         "signingServiceName": "apigateway"
       }
    }
}

AppSync确实在您提供的角色上承担角色，因此它需要允许AppSync承担角色并调用您的API网关API

您可以在其文档中找到API网关期望的标题的更多信息，如下所示：

Hi-Ionut，在这种情况下，我们不需要使用共享api网关端点，而不需要使用部署的端点url，比如XXXX.execute-api.region.amazonaws.com？
