Mix Path, Query and body parameters¶First, of course, you can mix Path, Query and request body parameter declarations freely and FastAPI will know what to do.And you can also declare body parameters as optional, by setting the default to None:...
Example: /users/{user_id} where user_id is a path parameter. Query Parameters: These are appended to the URL after a question mark. They're used for filtering, sorting, or passing optional data. Example: /users?age=30&city=NewYork Body Parameters: These are sent in the request body, ...
Check if there is an optional query parameter namedq(as inhttp://127.0.0.1:8000/items/foo?q=somequery) forGETrequests. As theqparameter is declared with= None, it is optional. Without theNoneit would be required (as is the body in the case withPUT). ...
