Hello,
I have noticed that only the query parameters marked as required are validated. For example let's say I have some optional parameter:
paths:
/things/{namespace}:
get:
parameters:
- $ref: '#/components/parameters/namespace'
- name: foo
required: false
in: query
schema:
$ref: '#/components/schemas/foo'
When I do GET /things/test_namespace?bla=something
validation passes, but changing required
to true
makes it fail with code 400 (expected behavior).
In parameters.js
file you can see the code:
function buildSchema(parameterObjects) {
const schema = { query: {}, headers: {}, params: {}, cookies: {} };
parameterObjects.forEach(parameterObject => {
const location = parameterObject.in;
const name = location === "header"
? parameterObject.name.toLowerCase()
: parameterObject.name;
const parameterSchema = {
type: "object",
properties: {
[name]: parameterObject.schema,
},
};
if (parameterObject.required) {
parameterSchema.required = [name];
}
lodash_1.default.mergeWith(schema[parameterLocationToRequestField(location)], parameterSchema, concatArraysCustomizer);
});
return schema;
}
As I checked the if statement is responsible for this behavior. I did a quick test and when you comment out the condition the optional parameter will also be validated. Of course I assume this condition is there for a reason and solution for the problem will be more sophisticated.
//if (parameterObject.required) {
parameterSchema.required = [name];
//}
In my opinion the optional parameters should also be validated, as we don't want to accept anything sent with GET request. At least the other framework for validation express-openapi-validator
I used before verified that.
Hello, It seems that we are unable to detect extra parameters in the query of a request. For example: GET /pets?foo=bar passes without error even if the parameter "foo" is not defined in my OAS 3 spec. Is it normal behavior? Is there any option to set in the library or ajv in order to get a sort of "additionalProperties : false" for the query parameters? Thanks
