研究方向

從連結的 StreamLambdaHandler.java 範例開始，檢查 serverless 容器針對 AWS 回應的二進位內容設定。使用 springdoc-openapi-starter-webmvc-ui 重現問題，接著判斷是否應預設辨識 application/javascript 和 text/css；當 Swagger UI 資產能透過 API Gateway 載入，且涵蓋預期的回應行為時，即表示完成。

由索引模型根據 Issue 內容生成。

描述

I don't know which component in the stack is wrong.

  • springdoc-openapi-starter-webmvc-ui will serve up swagger-ui/index.html, locally 100% and when deployed to a AWS API Gateway (HTTP-style) only some .js files and the .html file serve, the rest blowing up in the API Gateway response with no error message

I think the minimal repro is to add springdoc-openapi-starter-webmvc-ui (via pom.xml) to the ping controller example (which is a bad name for an endpoint because it clashes with the automatically provided route of AWS API Gateway, I usually have to rename it to pong)

I told the container to treat application/javascript and text/css as binary and API Gateway stopped trying to do something (unnecessary encoding/decoding) to the response and now swagger-ui loads.

I'm leaving this here because other issues have run into the same problem and came up with worse workarounds (like stop even trying to serve some content types on API Gateway at all)

That this works locally in tomcat makes me think that something is wrong with API Gateway or serverless-container.

public class StreamLambdaHandler implements RequestStreamHandler, Resource {
    private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
    static {
        try {
            handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);
            LambdaContainerHandler.getContainerConfig().addBinaryContentTypes("application/javascript");
            LambdaContainerHandler.getContainerConfig().addBinaryContentTypes("text/css");
        } catch (ContainerInitializationException e) {
            // if we fail here. We re-throw the exception to force another cold start
            e.printStackTrace();
            throw new RuntimeException("Could not initialize Spring Boot application", e);
        }
    }
}
