An HTTP 302 status code indicates redirection, often caused by:
- Authentication requirements.
- Backend misconfigurations.
Quick Fixes
- Check Backend Logic: Ensure no unintended redirection occurs.
- Add Authentication Headers:
const response = await axios.get(
`http://localhost:8080/api/product/${id}`,
{ headers: { Authorization: `Bearer ${token}` } }
);
- Debug with Tools: Use Postman to inspect backend responses.
Backend Adjustment
Return the correct status code in the controller:
@GetMapping("/product/{id}")
public ResponseEntity<Product> getProductById(@PathVariable int id) {
Product product = service.getProductById(id);
return product != null
? new ResponseEntity<>(product, HttpStatus.OK)
: new ResponseEntity<>(HttpStatus.NOT_FOUND);
}
By addressing these issues, you can eliminate unexpected redirections and ensure proper API responses.
