IOS Application to send data to a REST API service content-type definition error

Question

I managed to make an application to send data to a rest api service. The content type must be text/html. But whenever i run my app i get a 415 http code response which means not supported type of content. Here is my code:

NSURL *url = [NSURL new];

NSData *body = nil;

NSString *contentType = @"text/html"; 

NSURL *finalURL = [NSURL URLWithString:[NSString stringWithFormat:@"http://telesto.zapto.org:81/SMART_EdgeNode/EdgeNode/DataFeeds/3/addMeasurement"]];
NSString *yourString = @"geoX#35#geoY#65";





contentType = @"application/x-www-form-urlencoded; charset=utf-8";

body = [[NSString stringWithFormat:@"%@", yourString] dataUsingEncoding:NSUTF8StringEncoding];
NSString *putLength = [NSString stringWithFormat:@"%d",[body length]];



if (nil==finalURL) {

    finalURL = url;
}


NSMutableDictionary* headers = [[[NSMutableDictionary alloc] init] autorelease];
[headers setValue:contentType forKey:@"Content-Type"];
[headers setValue:@"mimeType" forKey:@"Accept"];
[headers setValue:@"no-cache" forKey:@"Cache-Control"];
[headers setValue:@"no-cache" forKey:@"Pragma"];
[headers setValue:@"close" forKey:@"Connection"];






NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:finalURL
                                                       cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                   timeoutInterval:60.0];
[request setHTTPMethod:@"PUT"];

[request setAllHTTPHeaderFields:headers];


[request setHTTPBody:body];
[request setValue:putLength forHTTPHeaderField:@"Content-Length"];

self.conn = [NSURLConnection connectionWithRequest:request delegate:self];

I guess atm there is something wrong with defining the content-type . Any help??

Thanks in advance

Answer 1

Ok i found it at last. It was this specific line that was causing the problem and had to do something with the content-type :

contentType = @"application/x-www-form-urlencoded; charset=utf-8";

After removing that i was able to send properly my string to the server.

Answer 2

I think the server's complaining that it doesn't know how to generate a response with the content type "mimeType".

Your Accept header should be "text/html" or whatever the content type you expect in the response, not "mimeType".

Update

After reading this again, I notice that you are setting the contentType to @"text/html", then to @"application/x-www-form-urlencoded; charset=utf-8". Which do you need? From the description, you want to sent text/html, but that is not what your sending. When you set contentType to @"application/x-www-form-urlencoded; charset=utf-8", text/html is lost.
