json - 使用 SwiftyJSON 或 Alamofire 将图像文件发布到服务器

Question

我正在尝试在 iPad 上拍照，然后使用 SwiftyJSON 或 Alamofire 将该图像文件发布到服务器。我必须将文件转换为 base64EncodedString 还是可以直接上传文件？

Answer 1

- (void) sendImageToServer
{
   UIImage *yourImage= [UIImage imageNamed:@"image.png"];
   NSData *imageData = UIImagePNGRepresentation(yourImage);
   NSString *postLength = [NSString stringWithFormat:@"%d", [imageData length]];

   // Init the URLRequest
   NSMutableURLRequest *request = [NSMutableURLRequest new];
   [request setHTTPMethod:@"POST"];
   [request setURL:[NSURL URLWithString:[NSString stringWithString:@"http://yoururl.domain"]]];
   [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
   [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
   [request setHTTPBody:imageData];

   NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
   if (connection) {
          // response data of the request
   }
}
