problem in uploading sample video file to the server - iphone

I want to upload sample video file to the server wen i pressed button. I used the code like below.
-(IBAction)buttonAction
{
NSMutableURLRequest* post = [NSMutableURLRequest requestWithURL: [NSURL URLWithString: #"http://115.111.27.206:8081/vblo/upload.jsp"]];
[post setHTTPMethod: #"POST"];
NSString *boundary = [NSString stringWithString:#"---------------------------358734318367435438734347"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[post 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=\"videofile\"; filename=\"videofile.3gp\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[[NSBundle mainBundle] pathForResource:#"video" ofType:#"3gp"]
dataUsingEncoding: NSASCIIStringEncoding]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[post setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:post returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
UIAlertView *statusAlert = [[UIAlertView alloc]initWithTitle:nil message:(NSString *)returnString delegate:self cancelButtonTitle:#"cancel" otherButtonTitles:#"ok", nil];
[statusAlert show];


You will have to set HTTP header also as follows:
NSMutableURLRequest* post = [NSMutableURLRequest requestWithURL: [NSURL URLWithString: #"http://115.111.27.206:8081/vblo/upload.jsp"]];
[post setHTTPMethod: #"POST"];
NSString *boundary = [NSString stringWithString:#"---------------------------358734318367435438734347"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[post 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=\"videofile\"; filename=\"videofile.3gp\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"video" ofType:#"3gp"]]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[post setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:post returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
or if you want asynchronous request then you can call initWithRequest method of NSURLConnection.

objective-c - Doesn't upload file's content

I want to upload a local word (or rtf) file to my server. Uploads the file without content. There is no error code or anything..
NSString *urlString = #"http://myserver.com/upload-c.php";
NSString *filename=#"xx.docx";
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"xx.docx"]];
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:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#\"\r\n",filename]] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:data]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding] autorelease];
NSLog(#"%#",returnString);

One obvious problem is with how you initialize your data variable.
Assuming "xx.docx" is the file you wish to upload, you have two problems.
You need to specify the full path to the file, not just the filename.
Since you are creating an NSURL from a file path, you need to use fileURLWithPath:, not URLWithString:.
Edit: Based on your comments, the file is located in the app's resource bundle. To get its fullpath you should do this:
NSString *fullPath = [[NSBundle mainBundle] pathForResource:#"xx" ofType:#"docx"];
NSData *data = [NSData dataWithContentsOfFile:fullPath];
Also, this line:
[body appendData:[NSData dataWithData:data]];
should simply be:
[body appendData:data];
And get rid of the calls to stringWithString:. Example:
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
should be:
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
and:
NSString *boundary = [NSString stringWithString:#"---------------------------14737809831466499882746641449"];
should be:
NSString *boundary = #"---------------------------14737809831466499882746641449";

How to upload image to server from gallery as JSON on iOS

How can I upload an image to a server from the gallery on iPhone as JSON? I tried the following:
[Loading startLoading:YES];
NSString *urlString = [NSString stringWithFormat:#"http://railsboxtech.com/singing/jsn_song/register_response.php?accesstoken=%#",Access_Token];
//username, password, name, email, country
NSString *parameter = [NSString stringWithFormat:#"username=%#&password=%#&fname=%#&email=%#&lname=%#&btnImage4=%#",userField.text,passField.text,fnameField.text,emailField.text,lnameField.text,btnImage4];
NSConnection *conn = [[NSConnection alloc] initWithDelegate:self];
[conn sendRequest:urlString withParaMeter:parameter withMethod:#"POST" withTag:1];
[conn startAsynchronousRequest];

if you want to upload an image as a string you must convert your image data to Base64, then you can use your above method:-
For converting to a base64 string, refer to this Stack Overflow answer. You can then use your code for uploading.
Another Way
You can directly upload an image like so:
-(void)uploadImage
{
NSData *imageData = UIImagePNGRepresentation(yourImage);
NSString *urlString = [ NSString stringWithFormat:#"http://yourUploadImageURl.php?intid=%#",1];
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:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"userfile\"; filename=\"%#\"\r\n", 1]] 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 stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
}

File upload server from iphone app [duplicate]

I want upload image to sever in iphone app I am using following code for PHP

}
Calling method
[self uploadImage:UIImageJPEGRepresentation(imageView.image, 1.0) filename:#"pig.jpg"];

if you think error in php code then first try this print_r($_FILES); and see what did you get in the $_FILES['userfile']

try this and also did you check in php by print_r($_FILES);
NSString *urlString = #"http://localhost/upload.php";

How to send xml or image data from iphone to a rails 3 server?

I am developing a hybrid app (rails 3 + iPhone) and I want to send a number of large strings and images to a rails 3 server. I want to do a POST method from iPhone. Can someone help me on how to do this ? since in this case there will be no form in the views how should I accept the data ? Thanks in advance

Here is some code for uploading an image through POST to an URL:
UIImage *myImage = [UIImage imageNamed:#"example.png"];
NSData *imageData = UIImageJPEGRepresentation(myImage, 0.9);
NSString *url = [NSURL URLWithString:#"http://postingurl.com/posthere"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------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=\"fileid\"; filename=\"myfile.png\"\r\n"]
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil e rror:nil];
[request release];
//Log return..
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
[returnString release];
You add more lines for Content-Disposition to include other fields.
