I am uploading the image to server by this code. It works fine in iOS deployment target 8.1 version but when I try to change the deployment target to 9.1 version the return data is getting null because [NSURLConnection sendSynchronousRequest:request1 returningResponse:nil error:nil]; is deprecated in 9.0.
Here is the issue.
sendAsynchronousRequest:queue:completionHandler:' is deprecated: first deprecated in iOS 9.0 - Use [NSURLSession dataTaskWithRequest:completionHandler:] (see NSURLSession.h).
But I am unable to do this using NSURLSession. Please help to modify this code to NSURLSession.
NSData *imageData = UIImageJPEGRepresentation(cameraImageViewOutlet.image, compression);
while ([imageData length] > maxFileSize && compression > maxCompression)
{
compression -= 0.1;
imageData = UIImageJPEGRepresentation(cameraImageViewOutlet.image, compression);
}
// Here is the uploading the image to server by POST
NSString *urlString1 = #"bfkgfdkhkghghj";
NSMutableURLRequest *request1 = [[NSMutableURLRequest alloc] init];
[request1 setURL:[NSURL URLWithString:urlString1]];

// Here we are doing the image to multipart...
NSString *boundary = #"---------------------------14737809831466499882746641449";

I am new IOS developer and I am facing a headache issue regarding to use multipart for uploading file and some text, i have tried a lot on here
The status code always return 400. I tired to test my web service with another way, such as build Rest client by HttpComponent API, using RestEASY client and both of them worked successfully, how funny!
I am using Xcode 6.1.1, my source code:
-(void)uploadPhoto {
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"http://localhost/my-rest-service"]];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:60];
[request setHTTPMethod:#"POST"];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:#"avatar_temp"], 1.0);
NSString *boundary = #"12345-6789-abc"; //
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
[body appendData:[[NSString stringWithFormat:#"%#--", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=%#\r\n\r\n", #"type"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", #"HELLO"] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the request
[request setHTTPBody:body];
// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%d", [body length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if(data.length > 0){
//success
NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"[String] %#", str);
}
}];
}
Any suggestions will help my investigation
Thanks

You forgot to add imageData so add:
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
A full working example:
[request setHTTPMethod:#"POST"];
NSData *imageData = UIImageJPEGRepresentation(imageToSave,0.9); //change imageToSave with your own UIImage defined
NSString *filenames = #"first field";
NSString *token = #"second field";
NSString *boundary = #"---------------------------14738723651466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
////+++ first form field for post -> for example a field called filenames see NSString above
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];
////--- the second field for form post-> we named token see above NSString
////+++
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
////---
////+++ the file used to upload /post
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"ceva.jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

// setting the body of the post to the reqeust

Now all the you want to make is check your php code on server side.
NSString *filenames = [NSString stringWithFormat:#"front_img"];

[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
/*Sending First Image ends here*/
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#",returnString);
A typical upload http body will look like:
--BOUNDARY_TEXT
Content-Type/Content-Disposition info key values
Base64 encoded file data ...
--BOUNDARY_TEXT
Content-Type/Content-Disposition info key values
Base64 encode file data.
--BOUNDARY_TEXT
You've done the first one, just continue append files according to the format seperatored by the BOUNDARY.
I am doing small project in which I need to send image file to server for that I am using multipart request.

This is my web service request.
I am setting content type like
[postbody appendData:[#"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
but still at server side I am getting #content-type =nill
*At server side we used ROR for webservice*
Please help me to solve this.
thanks in advance..
You should be setting content type by header parameters as
[request setValue:#"image/jpeg" forHTTPHeaderField:#"Content-Type"];
Please make the change.
For every multipart/form element, you need to set a proper Content-Type, e.g. the following for text-parameters:
[postbody appendData:[[NSString stringWithFormat:#"Content-Type: text/plain;charset=utf-8"] dataUsingEncoding:NSUTF8StringEncoding]];
I am very much new to ios.I have to upload an image to rest server from ios application. I have referred stackoverflow. But everytime the response is 400 which is bad request from client side. I am taking image from device document directory.Could some one post the exact code for image upload.Please refer the code I am using. I am not sure what to use as file name since I am downloading image from documents directory.

Hope it Helps!!
First convert UIImage to NSData as follows
UIImage *image = [UIImage imageNamed:#"example.png"];
NSData *data = UIImagePNGRepresentation(image);
or
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
Then form your request string
NSURL *url = [NSURL URLWithString:serverURL];
//Time out interval need to be tuned
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPMethod:#"POST"];
[request setHTTPBody: [requestString dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection sendAsynchronousRequest:request queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){
if (!data)
{
NSLog(#"Error downloading data: %#", error);
return;
}
NSError *error1;
NSDictionary *theDict = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error1];
DLog(#"Data received :%#", theDict);
}];
How can I create a post with an image and attach it as a featured image from iPhone app?
I am using wordpress with JSON API plugin
My url to create post: <-- Reference to this
http://www.example.com/api/create_post/?nonce=eea4bb4ce5&status=publish&title=Test&content=test%20content&categories=animals
Now I need to attach an image from the phone gallery to this url. How can I do this?
Try this. Use JSON POST method. You can append all your parameters like this.
-(void)uploadImage
{
NSString *method = #"";
NSString *username = #"";
NSString *token = #"";
NSString *urlString = [NSString stringWithFormat:#"%#",#"yoururl"];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSMutableData *body = [NSMutableData data];
// file
NSData *imageData = UIImageJPEGRepresentation( imageView.image, 0.8);
NSString *boundary = [NSString stringWithString:#"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition: form-data; name=\"image\"; filename=\".jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// parameter username
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"username\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[username dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// parameter token
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"auth_token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// // parameter method
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"method\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[method dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// close form
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#",returnString);
[returnString release];
}
Hope this may help you.
To full fill your requirement you need to send image file on web-service using by POST method
First chose image from Photo Library or take it from the camera and make data of that Image using following code.
NSString *imgName = [NSString stringWithFormat:#"ImageTest"];
NSData *imgData=UIImagePNGRepresentation(imgView.image);
NSString* urlstring = [NSString stringWithFormat:#"http://www.example.com/api/create_post/?nonce=eea4bb4ce5&status=publish&title=Test&content=test%20content&categories=animals&imageFile=%#",imgName];
NSLog(#"URL >> %#",urlstring);
NSURL url = [NSURL URLWithString:[urlstring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
//===============================================
NSMutableURLRequest postRequest = [[[NSMutableURLRequest alloc] init] autorelease];
[postRequest setURL:url];
[postRequest setHTTPMethod:#"POST"];
NSString boundary = [NSString stringWithString:#"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[postRequest addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [[NSMutableData alloc] init];
[postRequest addValue:contentType forHTTPHeaderField: #"Content-Type"];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition: form-data; name=\"userfile\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
imgName this is very important object in this code it's image which you need to pass in your web service which is shown as above.
[body appendData:[[NSString stringWithString:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#.png\"\r\n",imgName]] dataUsingEncoding:NSUTF8StringEncoding]]; //img name
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// Add Image imgData is Declare as Above.
[body appendData:[NSData dataWithData:imgData]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postRequest setHTTPBody:body];
NSURLResponse *response;
NSError error = nil;
NSData* data = [NSURLConnection sendSynchronousRequest:postRequest returningResponse:&response error:&error];
NSString *result=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
// NSString * jsonRes = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
NSLog(#"result = %#",[result JSONValue]);
It perfectly working with me ! I hope you may get help from here!
