Upload A File Into A Server - Objective C/Xcode/Mediawiki
提问by kamalbhai
I want to upload a UIImageinto a server. For this I am using the following lines of code ::
我想上传UIImage到服务器。为此，我使用以下代码行 ::
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
imageView.image = image;
NSData *pngData = UIImagePNGRepresentation(imageView.image);
NSString *imageFile = @"image.png";
NSString *docDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *filePath = [docDir stringByAppendingPathComponent:imageFile];
NSString *dataIS=[NSString base64StringFromData:pngData length:[pngData length]];
[pngData writeToFile:filePath atomically:YES];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"image\"; filename=\"image.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:pngData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
[self.parentViewController dismissModalViewControllerAnimated:YES];
}
But, I am getting the following error in gdb ::
但是，我在 gdb 中收到以下错误::
Your request could not be processed. Request could not be handled.
Your request could not be processed. Request could not be handled.
I am also confused over the proper use of urlStringi.e. I am doubtful over my correct use of it.
我也对urlStringie的正确使用感到困惑，我怀疑我正确使用它。
If I however use the following urlString, I am able to upload my image file into the server ::
但是urlString，如果我使用以下内容，则可以将图像文件上传到服务器 ::
NSString *urlString = [NSString stringWithFormat:@"http://xxxx.com/mediawiki/api.php?action=upload&filename=image.png&url=%@&token=%@", url, token] ;
With reference to the APIfor mediawiki(http://www.mediawiki.org/wiki/API:Upload), can someone help me to sort it out ?? Thanks and Regards.
参考APIfor mediawiki(http://www.mediawiki.org/wiki/API:Upload)，有人可以帮我整理一下吗？？感谢致敬。

If you want to send image to server,send by data in encoded form,server can handle encoded form of image and they will get image data in encoded from.
如果你想将图像发送到服务器，通过编码形式的数据发送，服务器可以处理图像的编码形式，他们将从编码中获取图像数据。

I have same problem to upload multiple images and data but i am use AFNetworking class and Upload multiple images into server.
我在上传多个图像和数据时遇到同样的问题，但我使用 AFNetworking 类并将多个图像上传到服务器。
NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"your URL"]];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
path = [[NSString alloc] initWithString:[URL absoluteString]];
vdict = @{
// Your Parameter Pass
};
[self checkmultiple:vdict];
-(void)checkmultiple:(NSDictionary*)vdict
{
AFHTTPRequestOperation *op = [manager POST:path parameters:vdict constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
for(i = 0;i<[appDelegate.gblarrydata count];i++)
{
NSString *paths = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"New Folder"];
// NSLog(@"%@",paths);
NSString *documentsDirectory = paths;
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[[appDelegate.gblarrydata objectAtIndex:i]valueForKey:@"nameimage"]];
NSData *data1 =[[NSData alloc]initWithContentsOfFile:getImagePath];
NSString *data2 =[[appDelegate.gblarrydata objectAtIndex:i] valueForKey:@"Note"];
[formData appendPartWithFileData:data1 name:[NSString stringWithFormat:@"pimage%d",i+1] fileName:[NSString stringWithFormat:@"pimage%d.jpg",i+1] mimeType:@"image/jpeg"];
if(![data2 isEqualToString:@""])
{
[formData appendPartWithFormData:[data2 dataUsingEncoding:NSUTF8StringEncoding]
name:[NSString stringWithFormat:@"pnotes%d",i+1]];
}
}
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(@"Upload success");
NSString *returnString = [NSString stringWithFormat:@"%@",[responseObject JSONRepresentation]];
NSLog(@"Reg Date:%@",returnString);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(@"Error:%@",error);
}];
[op start];
}

I had the same problem. I used ASIHTTPRequest, for uploading files, it works fine.
我有同样的问题。我使用 ASIHTTPRequest上传文件，它工作正常。
Uploading:
上传：
Imagefile:
图像文件：
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request addPostValue:@"Ben" forKey:@"names"];
[request addPostValue:@"George" forKey:@"names"];
[request addFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photos"];
[request addData:imageData withFileName:@"george.jpg" andContentType:@"image/jpeg" forKey:@"photos"];
With Other data simultaneously:
与其他数据同时：
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
// Upload a file on disk
[request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg"
forKey:@"photo"];
// Upload an NSData instance
[request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];
for Downloading to desired Path:
下载到所需路径：
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadDestinationPath:@"/Users/ben/Desktop/my_file.txt"];
