nsurlrequest

问题 I have been googling this problem for hours now, and I can't seem to find a solution.

问题 I am writing the swift code to send a http post request to the php server. But my php script always get the strange post body because the parameters are wrapped by the Option(), If I send parameters like "id=john&password=1234", the server will get Optional(id=john&password=1234).
