Migrate legacy req.param(name)

The req.param(name) helper that used to magically look up values from multiple places has been removed. This potentially confusing and dangerous method of retrieving form data has been removed. You will now need to specifically look for the submitted parameter name in the req.params, req.body, or req.query object.

Examples

Replacing req.param('body') and req.param('query')

Replace req.param('body') with req.body and
req.param('query') with req.query.

diff
Copy
app.get('/', (req, res) => {
  // Before
- const reqBody = req.param('body');
- const reqQuery = req.param('query');
  // After
+ const reqBody = req.body;
+ const reqQuery = req.query;
});

Replacing req.param('paramName')

Replace req.param('paramName') with req.params.paramName.

diff
Copy
app.get('/user/:id', (req, res) => {
  // Before
- const userId = req.param('id');
  // After
+ const userId = req.params.id;
});
