HTTP Post Request with Body Contents fails - objective-c

Question

i'm trying to send an HTTP post request from my objective-c application to my server. i tried many different things, but i can't get the request to work with the content on request body. With the parameters on the url it work just fine, but i need to send a string with reserved characters.
This is my class responsible for the request:
#import "CLPUtilRequest.h"
static NSString *baseURL = #"http://localhost:8080/cl-mobile";
#implementation CLPUtilRequest
//Parameteres on the URL (working!!)
+ (NSData *) makeHttpRequest:(NSString *)url {
//Set info for webservice
NSString *urlString = baseURL;
urlString = [urlString stringByAppendingString:url];
NSURL *resquestUrl = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:resquestUrl];
[request setHTTPMethod: #"POST"];
[request setValue:#"application/http" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
//Call the webservice
NSError *errorReturned = nil;
NSHTTPURLResponse *theResponse =[[NSHTTPURLResponse alloc]init];
return [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
}
//Parameteres on the bodt (not working!!)
+ (NSData *) makeHttpRequestContentOnBody:(NSString *)url withContent:(NSString *)content {
NSData *postData = [content dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *errorReturned = nil;
NSHTTPURLResponse *theResponse =[[NSHTTPURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
return data;
}
#end
And this is where i call the request.
NSString *contentString = #"chaveUsuarioEmpresa=";
contentString = [contentString stringByAppendingString:appDelegate.clinica.chave];
contentString = [contentString stringByAppendingString:#"&chaveAgendamento="];
contentString = [contentString stringByAppendingString:appDelegate.agendamento.chave];
contentString = [contentString stringByAppendingString:#"&anamnese="];
contentString = [contentString stringByAppendingString:self.texto.text];
NSData *dataResponse = [CLPUtilRequest makeHttpRequestContentOnBody:#"/agendamento/anamnese/save" withContent:contentString];
After calling the request, my errorReturned gives me the following (debugging): NSURLError * domain: #"NSURLErrorDomain" - code: -1002
I tried to do as described in this link (but didn`t make it): Sending an HTTP POST request on iOS
Thanks in advance!

Answer 1

according to Apple's Error Codes -1002 is the code for an unsupported url. and actually you are sending it to /agendamento/anamnese/save, as you don't prepend baseURL as you do in the other call
+ (NSData *) makeHttpRequest:(NSString *)url {
//Set info for webservice
NSString *urlString = baseURL;
urlString = [urlString stringByAppendingString:url];
NSURL *resquestUrl = [NSURL URLWithString:urlString];
while in makeHttpRequestContentOnBody:withContent: you use the unchanged passed in url string /agendamento/anamnese/save
Try
+ (NSData *) makeHttpRequestContentOnBody:(NSString *)url withContent:(NSString *)content
{
NSData *postData = [content dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSString *urlString = baseURL;
urlString = [urlString stringByAppendingString:url];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *errorReturned = nil;
NSHTTPURLResponse *theResponse =[[NSHTTPURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
return data;
}
