             Summary: camel-openapi-validator doesn't work for contract-first api's
                 Key: CAMEL-22116
                 URL: https://issues.apache.org/jira/browse/CAMEL-22116
             Project: Camel
          Issue Type: Bug
    Affects Versions: 4.11.0, 4.10.4
            Reporter: Bjorn Beskow


Using camel-openapi-validator with an contract-first api such as [https://github.com/apache/camel-spring-boot-examples/openapi-contract-first] results in an HTTP 404 for all endpoints:

 
{code:java}
> curl http://localhost:8080/api/v3/pet/1
Validation failed.
[ERROR][GET ] No API path found that matches request ''.{code}
This is caused by the CamelHttpPath set to '' by camel-platform-http, which is used to select endpoint from the openapi specification.

The "CamelPlatformHttpContextPath" is however correctly set, and hence the correct value for path can be calculated:
{code:java}
String path = exchange.getMessage().getHeader(Exchange.HTTP_PATH, String.class);
// Workaround for camel-platform-http which does not properly set HTTP_PATH header
if (StringUtils.isEmpty(path)) {
    String uri = exchange.getMessage().getHeader(Exchange.HTTP_URI, String.class);
    String contextPath = exchange.getMessage().getHeader("CamelPlatformHttpContextPath", String.class);
    if (StringUtils.isNotEmpty(contextPath) && uri.startsWith(contextPath)) {
        path = uri.substring(contextPath.length());
    }
} {code}
With path correctly set, the corresponding endpoint can be found in the openapi specification, which corrects the problem.

 

I'll submit a merge request with the above patch.
