I want to upload one image to server using http post method.
the requirement is like in the body data should be attached as byte stream.
I converted image to NSData and attached that data to body of NSUrlrequest.
but i am getting 404 in status code of response.
NSMutableData *body = [NSMutableData data];
[body appendData:[NSData dataWithData:UIImageData]];
[request setHTTPBody:body];
but i am getting 404 error in status code.
is byte stream is same as NSData ?
if not then how to send byte stream data to server using NSURLConnection ?
Thanks in advance.
What about the URL you're using to send the image to?
A 404 error code translates to Not Found (http://en.wikipedia.org/wiki/HTTP_404), so the first step should be making sure yore using a valid URL.
Try to make the upload that way:
NSData *yourData = //load your data here;
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:UPLOAD_URL]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"%#\"\r\n", UPLOAD_FILE, UPLOAD_FILE] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:yourData]];
[postbody appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
[connection start];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

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 developing an iOS app and I am using node.js for server side scripting. I am facing problem in uploading image to server from iOS app. It is working fine if I am uploading image from webpage form. But if uploading from app side it is not working.
//test file
h3 Pic Upload
form(action='/pic_upload', method='post',enctype='multipart/form-data')
| user_pic:
input(type='file', name='user_pic')
input(type='submit')
//app.js
var userlogin =require('./routes/userlogin');
app.post('/pic_upload', userlogin.picUpload);
//userlogin.js
//picUpload function
exports.picUpload = function(req, res) {
console.log(req.files); // showing undefined, when called from IOS app
// pic upload script...
});
I have tried sending image from app side as data or file parameter but it did not work. How to send the file parameter from app side so that I can easily upload the image to server? Kindly suggest a way to tackle the problem.
This code works in my app. Try this.
NSData *imgData = UIImageJPEGRepresentation(newImg, 0.2);
NSString *str = #"displayImage";
NSString *urlString = #"http://some.url.com/post";
// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSString *boundary = [NSString stringWithFormat:#"---------------------------14737809831464368775746641449"];
// 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:#"\r\n--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"currentEventID\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"52344457901000006" dataUsingEncoding:NSUTF8StringEncoding]];
// add image data
if (imgData) {
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// [body appendData:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"displayImage\"; filename=\"image.jpg\"\r\n"]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"image.jpg\"\r\n", str] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imgData];
[body appendData:[[NSString stringWithFormat:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// set URL
[request setURL:[NSURL URLWithString:urlString]];
NSString *bodyStr = [[NSString alloc]initWithData:body encoding:NSUTF8StringEncoding];
NSLog(#" %#",bodyStr);
NSURLConnection *lot_Connection=[[NSURLConnection alloc]initWithRequest:request delegate:self];

I have a simple question- I'm currently writing a specific part in my app related to sending data to server.
I tried to send text, succeeded. Sent image, succeeded.
What I'm trying to do now is to send them both within one POST request.
I figured out that I need to use something that is called multipart/form-data and boundaries, but I haven't found anymore info about it.
So how can I send both text and image in one, simple POST request? And how can I check for errors during upload, afterwards etc.?
Thanks!
Reference code I've written but sending 0 bytes of info:
NSData *imageData = UIImageJPEGRepresentation(sendImage, 1.0);
// setting up the request object now
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://posttestserver.com/post.php?dir=something"]];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------54737809831466490885746641449";
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:[#"Content-Disposition: form-data; name=\"userfile\"; filename=\"reportingImage.jpg\"rn" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-streamrnrn" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"rn--%#--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: text/xml" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[[alertView textFieldAtIndex:0] text] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
This is a working snippet that sends text and image, optionally a few texts with a few params per each
//After dismissing the alert, we get its text (user location and notes) and the picture he took
NSMutableData *body = [NSMutableData data];
NSURL *url = [NSURL URLWithString:#"http://posttestserver.com/post.php?dir=Doda"]; //Test server, you can access it online to see the upload
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
[req setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449"; //I have no idea what this is, but without it the code won't work

You probably want to use a network library like AFNetworking, and save yourself some time :)
Here it is my code to upload an audio file. I tried lot of questions and answers in stackoverflow. But still i am not getting any improvement on this. I have to upload an audio file with a php link. If i do that, i am getting response like "already exists" always. I tried to change the filename and upload it. still getting same response. Actually i have to receive a response from the server as link of a file i uploaded. I am not having any knowledge about php. Anyone help me with this. Any help would be appreciated to clear my issue.

I suspect this line
Also check your input variable
