在AWS API网关中,我使用自定义lambda授权程序来验证请求标头。我需要根据验证结果更新现有的标头或添加新的标头。 以下是Java中的Lambda授权者逻辑,验证工作符合预期。不管更新标头值如何,后端lambda中接收的事件对象都是空的。
@Override
public AuthPolicy handleRequest(APIGatewayProxyRequestEvent event, Context context) {
LambdaLogger logger = context.getLogger();
logger.log("Loading Java Lambda handler of Proxy");
logger.log("Event Object : " + event.toString());
Pattern requestIdpattern = Pattern.compile("[0-9a-f]{4}-[0-9A-Z]{3}");
ProxyRequestContext reqContext = event.getRequestContext();
boolean isValid = false;
Map<String, String> headers = event.getHeaders();
if (requestIdpattern.matcher(headers.get("x-request-id")).matches()) {
isValid = true;
headers.put("x-jid", UUID.randomUUID().toString());
}
if (isValid) {
AuthPolicy authPolicy = new AuthPolicy("XXXX",
PolicyDocument.getAllowPolicy("us-east-1", reqContext.getAccountId(), reqContext.getApiId(),
reqContext.getStage(), HttpMethod.getHttpMethod(reqContext.getHttpMethod()),
reqContext.getResourcePath()));
return authPolicy;
} else {
AuthPolicy authPolicy = new AuthPolicy("XXXXXX",
PolicyDocument.getDenyPolicy("us-east-1", reqContext.getAccountId(), reqContext.getApiId(),
reqContext.getStage(), HttpMethod.getHttpMethod(reqContext.getHttpMethod()),
reqContext.getResourcePath()));
logger.log("Auth Policy Response Object : " + authPolicy.toString());
return authPolicy;
}
}
请让我知道如何配置授权者,以便在成功授权后将对API网关请求的输入请求发送到集成服务。
