Please tell me how to submit the url parameter username=test&userpwd=test&confirm=test&Submit= when logging in to the PHP user system. Why can't the registration be submitted? It shows that the submission failed. Direct form submission can be successful.
If the url is submitted directly, maybe your server does not support get submission, or the "registration" in username=test&userpwd=test&confirm=test&Submit=registration needs to be converted to the encoding
