Uploading Image to the web service - Beginner

问题


I have to upload an image taken via the camera or uploaded via uiimagepickerview. I am using ASIHTTPRequest.

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

[request setFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photo"];

1.) Since i am taking the photo from the iPhone camera or uploading it from the uiimagepickerview, i need to know what value should i set for setFile (replacement text for @"/Users/ben/Desktop/ben.jpg") ?

2.) I also need to test this application, so does anyone know the corresponding PHP code where i could display the image taken (on the web browser). Tutorials or sample codes

To get answer on the 1st question, please, take a look on the following code fragment:

#import <MobileCoreServices/MobileCoreServices.h>

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    BOOL isImage = ([[info objectForKey:UIImagePickerControllerMediaType] isEqualToString:kUTTypeImage]);
    if (isImage) {
        self.request = [ASIFormDataRequest requestWithURL:url];
        UIImage *originalImage = [info objectForKey:UIImagePickerControllerOriginalImage];
        NSData *imageData = UIImageJPEGRepresentation(originalImage, 0.7);
        [self.request setData:imageData
                 withFileName:@"photo.jpg"
               andContentType:@"image/jpeg"
                       forKey:@"photo"];
        [self.request start];
    }
}

Please consider to add property into your UIImagePiclerController delegate class

@property(nonatomic, retain) ASIFormDataRequest *request;

It will allow you to stop request or at least set it's delegate to nil, if your object is deallocated, by simply implementing

- (void) dealloc {
    [self.request cancel];
    self.request.delegate = nil;
    [request release];
    [super dealloc];
}

You should Add Image to the Request Body as image data.
