当我从另一个 url 下载图像时，将图像上传到特定 url 的正确方法是什么？

Question

I am successfully completed 75% of my task.The main problem is image uploading. Connection is established.but encoding data cannot be uploaded.here i am writing my code like this way

UIImage *naveen = [UIImage  imageWithData: [NSData dataWithContentsOfURL:[NSURL  

URLWithString:@"http://www.watblog.com/wp-content/uploads/2011/11/b.jpg"]]];

myimages.image=naveen; 

by using the above code i load the image very successfully.

the above code i write in did load method.

After that i take an IBAction in that i write below code

NSData *imageData = UIImageJPEGRepresentation(myimages.image, 90);

NSString *encodedImage = [Base64 encode:imageData];

NSLog(@"my encoded image is 6666%@",encodedImage);

//here i am getting encoded image data

it is also successful

NSString *urlString = @"http://192.168.1.105:9966/PC/store";


NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

    [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:@"rn--%@rn",boundary] 

dataUsingEncoding:NSUTF8StringEncoding]];


  [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; 

name=\"encodedImage\"; filename=\"http://www.watblog.com/wp-

content/uploads/2011/11/b.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];


[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] 

dataUsingEncoding:NSUTF8StringEncoding]];

    [body appendData:[NSData dataWithData:imageData]];

    [body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] 

dataUsingEncoding:NSUTF8StringEncoding]];

[request setHTTPBody:body];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil 

error:nil];

NSString *returnString = [[NSString alloc] initWithData:returnData 

encoding:NSUTF8StringEncoding];

NSLog(returnString);

}

Answer 1

That seems more like a problem with backend server. Try to upload file with any other method - ie from simple HTML form.

This may not be a clue, but why you're using full URL for a filename?

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"encodedImage\"; filename=\"http://www.watblog.com/wp-content/uploads/2011/11/b.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
