Post request from iPhone using ASIFormDataRequest not working - iphone

Newbie to Rails/iOS here. I have a rails blog application. I'm trying to upload a post from iOS using an HTTP POST method with ASIFormDataRequest. Here's the code that get's called:
NSURL *url=[[NSURL alloc] initWithString:#"http://localhost:3000/posts"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"Ben" forKey:#"name"];
[request setFile:#"star.png" forKey:#"image"];
[request startSynchronous];
NSString *response = [request responseString];
NSLog(#"response:: %#", response);
When I run this code, nothing happens. My server does not get contacted. I get response:: (null). Any idea why?
EDIT I found out that star.png needed to have its full file address. Now the POST works fine, but neither the name or image get saved into the db. A new post with empty name and image gets created. Any idea why?

why you are using localhost here?
NSURL *url=[[NSURL alloc] initWithString:#"http://localhost:3000/posts"];
use your web server ip instead of localhost
NSURL *url=[[NSURL alloc] initWithString:#"http://yourservername:3000/posts"];

NSData *imageData = [NSData dataWithContentsOfFile:imagePath];
NSURL *url=[[NSURL alloc] initWithString:#"http://localhost:3000/posts"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"Ben" forKey:#"name"];
[request setPostValue:imageData forKey:#"image"];
[request startSynchronous];
For the "imagePath" is the path to your image. The full path.

Iphone image uploading -- 500 Error

I am new to iphone development. I want to share image from my device to server which is handled by myself. I done this in both android as well as from iphone device. Its very well posted from Android, but i get 500 error message from server whenever i posted through iphone. I really dont know where i made mistake. Is there any protocol blocks iphone whenever i communicate with server.
NSString *uploadUrl = [NSString stringWithFormat:#"--My url-- "];
NSURL *url = [NSURL URLWithString:uploadUrl];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
NSMutableString *m_strUploadedFileName = [NSMutableString stringWithFormat:#"pic_%#_%#.png",dateString,[prefs objectForKey:#"EmailId"]];
NSData *imageData = UIImageJPEGRepresentation(m_imageFish.image, 0.2);
NSLog(#"image data is %#",imageData);
[request setData:imageData withFileName:m_strUploadedFileName andContentType:#"image/jpg" forKey:#"--server parameter to send-- "];
[request setDefaultResponseEncoding:NSISOLatin1StringEncoding];
[request setDelegate:self];
[request setRequestMethod:#"POST"];

Upload a image on server iPhone

I am new to iPhone. I want to upload an image to a server. I have url
http://lifestander.com:8080/fileupload/uploadfile.html?username=tom&password=1234&directory=ebay&filename=fantacy.jpg
I use the following method for uploading the file, but the result in console is: {"success":"false", "message":"Authentication Failed"}
I do not understand the output in the console. So please tell me what do I do wrong, or improve my code. What to do?
Thanks.
-(void)uploadFile{
UIImage* theImage = [UIImage imageNamed:#"images.jpg"];
NSString* path = [[NSBundle mainBundle] pathForResource:#"images" ofType:#"jpg"];
NSString *photoUploadURLString=#"http://lifestander.com:8080/fileupload/uploadfile.html";
NSURL *url = [NSURL URLWithString: photoUploadURLString];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setUseKeychainPersistence:YES];
// Upload an image
NSData *imageData = UIImageJPEGRepresentation(theImage,1.0);
[request addPostValue:#"tom" forKey:#"username"];
[request addPostValue:#"1234" forKey:#"password"];
[request addPostValue:#"ebay" forKey:#"directory"];
[request setData:imageData withFileName:#"images.jpg" andContentType:#"image/jpg" forKey:#"filename"];
[request setDelegate:self];
[request setDidFinishSelector:#selector(uploadRequestFinished:)];
[request setDidFailSelector:#selector(uploadRequestFailed:)];
[request startAsynchronous];
}
I'm not sure whether it's a code fault, since there is no crash and you receive a response. {"success":"false", "message":"Authentication Failed"} means that there is something wrong with the authentication. Check if there is any login/password/acces key required to upload your file and if yes, implement it.

Log into website with ASIHttpRequest

I have a website that i want to log into from my iphone in a iphone app i am making, i followed the documentation on ASIHttpRequests website but all i get from the response string is the html code for the login page , but i get a OK http code, Why is this happening?
Here is my code :
-(IBAction)fetchData:(id)sender
{
NSURL *url = [NSURL URLWithString:#"http://www.rssit.site90.com/login.php"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request shouldPresentCredentialsBeforeChallenge];
[request setRequestMethod:#"POST"];
[request setPostValue:#"" forKey:#"username"];
[request setPostValue:#"" forKey:#"password"];
[request setDelegate:self];
[request startAsynchronous];
//Add finish or failed selector
[request setDidFinishSelector:#selector(requestLoginFinished:)];
[request setDidFailSelector:#selector(requestLoginFailed:)];
}
- (void)requestLoginFinished:(ASIHTTPRequest *)request
{
NSString *yourResponse = [request responseString];
NSLog(#"%#", yourResponse);
}
The form on that page is doing a get, not a post. Your server is probably not expecting POST data, and is looking at query string params instead. Change to
[NSURL URLWithString:#"http://www.rssit.site90.com/login.php?username=YOURUSERNAME&password=YOURPASSWORD"];
and set the requestMethod to GET.

upload image to server

i want to upload an
UIImage
to a server.
the problem i dont know how to add it to my post to the server.
until now i sent post with thia:
NSString *reqURL = [NSString stringWithFormat:#"url"];
reqURL = [reqURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:reqURL]];
NSURLResponse *resp = nil;
NSError *err = nil;
NSData *response = [NSURLConnection sendSynchronousRequest: theRequest returningResponse: &resp error: &err];
there is any different way to do for image?
Use ASIHttpRequest
-(void)uploadImage{
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:UIImageJPEGRepresentation(myUIImage) withFileName:#"myphoto.jpg" andContentType:#"image/jpeg" forKey:#"photo"];
[request setDelegate:self];
[request setDidFinishSelector:#selector(uploadRequestFinished:)];
[request setDidFailSelector:#selector(uploadRequestFailed:)];
[request startAsynchronous];
}
This answer points to this wrapper framework that should make it easy to do what you want without dealing with HTTP header strings and so on.
Basically, you'll turn your UIImage into an NSData object using a function like UIImagePNGRepresentation() and then upload it over HTTP.
