Question

What are the steps to verify a query's accuracy and effectively manage any errors that may arise

When using my API, the endpoint '/api/students' will display all student names. If a req.query is input with a specific name, such as "John", the endpoint becomes '/api/students?name=John'. I have implemented regex to ensure that only characters and spaces are allowed in the input:

const re = /^[a-zA-Z ]*$/;
if (!re.test(name)) {//error code

However, if a user accidentally inputs the endpoint as '/api/students?firstnames=John', they will still receive all names instead of triggering an error handling response as a bad request. How can this situation be addressed?

Answer №1

If I grasp your issue correctly, it seems to revolve around distinguishing between the query parameter name and firstnames. It might be beneficial to limit user input choices for query parameters (e.g., name,

age</code) through UI controls known as "filters."</p>

<p>It appears that the API is disregarding the unfamiliar query parameter <code>firstnames

and returning all student data instead. To address this, consider handling unexpected query parameters in the API endpoint implementation by returning a 400 BAD REQUEST error when receiving an unknown parameter like firstnames.

To verify these parameters, employing regex checks seems like a promising approach. Whether implementing validation on the UI or API side, these strategies can help regulate query parameter types:

UI Approach:

Restrict direct user entry of query parameter types
Prompt users to input specific query parameters like name
Construct the query string with user-inputted parameters

API Approach:

Validate query parameters to ensure they are recognized
Return a 400 BAD REQUEST response for any unrecognized parameters rather than ignoring them
