-----------------------------------
Summary: camel-openapi-java - Empty server url due to
X-Forward-Headers
Key: CAMEL-20490
URL: https://issues.apache.org/jira/browse/CAMEL-20490
Project: Camel
Issue Type: Improvement
Components: camel-rest-openapi
Reporter: Claus Ibsen
Fix For: 4.x
This looks a bit mysterious as restConfiguration has `useXForwardHeaders=true`
as default which causes the url to be empty or just the base path (but you can
have / as base-path)
{code}
{
"openapi" : "3.0.0",
"info" : { },
"servers" : [ {
"url" : ""
} ],
"paths" : {
"/account" : {
"get" : {
"operationId" : "get-c5d3",
"responses" : {
"200" : {
"description" : "Output type",
"content" : {
"application/json" : {
"schema" : {
"$ref" : "#/components/schemas/Account"
}
}
}
}
}
}
}
},
"components" : {
"schemas" : {
"Account" : {
"type" : "object",
"properties" : {
"accountNumber" : {
"type" : "string"
},
"accountName" : {
"type" : "string"
},
"balance" : {
"type" : "number",
"format" : "double"
}
}
}
}
}
}
{code}
Notice how the server urls is "" (empty).
But the server url has been computed to http://0.0.0.0:8080 by default prior to
setupXForwardedHeaders is invoked.
I am not sure why this line is as-is
