[Question]: How to retrieve form data from Playwright Request object?

[yannsartori]

Your question

I am adding a custom route handler to a Playwright page and I am trying to inspect the request passed into the handler. For context here is a following code snippet:

def handler(route: Route, request: Request):
    # Do things with `request`
    ...

await page.route('**/*', handler=handler)

For POST/PUT requests with a Content-Type of application/json, I have been able to successfully inspect the payload by using request.post_data_buffer. However, when the Content-Type is multipart/form-data, I have not been able locate where I can get the form data. All of the post_data, post_data_buffer, and post_data_json properties have a value of None, and I couldn't see anything else in the documentation which could contain the form_data.

I added a similar question to the generic playwright GitHub here

Could this also be a bug? I was not sure which is why I hesitated to open this as a bug
