Url parameters not using provided value in Swagger UI

[akuchcik]

I'm resending conversation and issue report from https://github.com/springdoc/springdoc-openapi :

Any value provided inside the parameter input field is ignored and the resulted url only has {parameter} inside it instead of the actual value.

• What version of spring-boot you are using? 3.3.4
• What modules and versions of springdoc-openapi are you using? springdoc-openapi-starter-webmvc-ui 2.6.0

Issue occurs when using springdoc-openapi-starter-webmvc-ui with custom yaml file Using the same file with docker image swaggerapi/swagger-ui doesn't result with this issue and works as expected

I found out that the reason for this is the "=" (equals sign) in the path. This path works: /data/logging-status/broker/{broker-identifier} but this path doesn't work: /data/logging-status/broker={broker-identifier}

I created a new spring boot application with minimal requirements https://github.com/akuchcik/springdoc-url-parameter-bug :

• springdoc-openapi-starter-webmvc-ui 2.6.0 dependency
• custom yaml file (which I mentioned earlier) in class path (in resources folder)
• and OpenApiConfig class

Custom yaml file (same problem on 3.1.0 version):

Reply from @bnasslahsen : Your expected behavior is invalid. You are declaring broker-identifier as path variable, whereas it should be declared as query parameter.

NOTE: OpenAPI defines a unique operation as a combination of a path and an HTTP method:

Answer: if I define it as query the resulted url looks like this: "http://localhost:8080/data/logging-status/broker={broker-identifier}?broker-identifier=test"

It just adds a query at the end of the url. I am not using a query as I'm not using "?" after the path. I am specifying an entry in a list. This describing of entries/keys in a list of elements is defined in RESTCONF Protocol - RFC 8040. When using docker image swaggerapi/swagger-ui it is working as expected.

REPLY: @akuchcikm,

Is the OpenAPI spec correct ? If it's the case, then it's not a sprindoc issue. You should reach the https://github.com/swagger-api/swagger-ui/issues instead.

[akuchcik]

When using env variable URL instead of URLS in docker image swaggerapi/swagger-ui I get the same error, but when using springdoc that problem persists in both cases (setting url or urls in custom swagger controller).

Looks similar to https://github.com/swagger-api/swagger-ui/issues/9979 It looks like a regression introduced in 5.17.8 and later
