如何使用 aws_apigatewayv2 将 Lambda 链接到 React 静态应用程序

Question

我正在尝试构建一个 cdk 堆栈来通过 api 网关将 lambda 函数连接到 React 静态网站。

from aws_cdk import (

    Stack,

    aws_lambda as _lambda,

    # aws_s3_notifications as s3_notify,

    aws_s3 as s3,

    aws_iam as iam,

    aws_s3_deployment as s3_deployment,

)

 

from aws_cdk.aws_apigatewayv2 import HttpApi, HttpMethod

from aws_cdk.aws_apigatewayv2_integrations import (

    HttpLambdaIntegration,

)

# Create the Lambda function

        lambda_function = _lambda.Function(

            self,

            id="MtLambdaFunction",

            runtime=_lambda.Runtime.PYTHON_3_8,

            handler="main.handler",  # Replace with your actual handler

            code=_lambda.Code.from_asset("./Backend/main.zip"),

            # Add other Lambda function configurations

        )

 

        # Grant the Lambda function permission to read from the S3 bucket

        models_bucket.grant_read(lambda_function)  #

 

        # create the api gateway

 

        react_ui_integration = HttpLambdaIntegration(

            id="ReactIntegration", handler=lambda_function

        )

 

        http_api = HttpApi(self, "ReactHttpApi")

 

        http_api.add_routes(

            path="/translate",

            methods=[HttpMethod.ANY],

            integration=react_ui_integration,

        )

 

我从文档获取了api网关的代码示例。

导入时收到以下消息

aws_apigatewayv2_integrations

Import "aws_cdk.aws_apigatewayv2_integrations" could not be resolved

我安装了该软件包，因此收到一条消息错误，指出该构建包已从 10.3.0 降级至 3.4.344

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behavior is the source of the following dependency conflicts.

aws-cdk-lib 2.110.0 requires constructs<11.0.0,>=10.0.0, but you have constructs 3.4.344 which is incompatible.

顺便说一句，我使用的是虚拟环境并安装了以下软件包：

aws-cdk-lib==2.110.0

constructs>=10.0.0,<11.0.0

那么如何直接从 aws-cdk-lib 使用

aws_apigatewayv2_integrations

而无需手动安装呢？ 我选择了 v2 版本，这样我就可以使用 HTTP Api。您认为这是最好的选择吗？或者，最好使用 v1

aws_apigateway

。

如果您在部署此网关以链接 React 静态应用程序和 lambda 函数时需要考虑任何其他事项，请告诉我，因为这是我的第一个项目

cdk

Answer 1

升级

aws-cdk-lib

到最新版本：

aws-cdk-lib==2.114.1
constructs>=10.0.0,<11.0.0
