multipartform-data

问题 I need to POST a request. The request has 3 parameters, 'email_id' , 'location' and 'image_data'. The value for 'image_data' contains NSData jpeg representation of a UIImage. The request must be submitted using a content type of multipart/form-data. How can I create the NSMutableRequest for posting this request? How should I set the boundary? Is the boundary required for the entire packet or is it enough only for the image part? 回答1: This link: http://iphone.zcentric.com/2008/08/29/post-a

问题 This may sound, or actually be, a stupid question but I need to find the best way to proceed with a project I am on. I have a multipage webform, using the multiview control. That multiview is in an updatepanel control, and everything works great so far. My question is about users with javascript disabled.
