[OGo-Developer] NSURL different in libFoundation and GNUstep base?

[Sebastian Reitenbach]

Hi,

i try to create a NSURL and then to retrieve some data from it. This is 
working with my test program on gnustep-base, but not with libFoundation.

below are the two test program sources, and their output. In gnustep-base 
environment, everything is working as I expect it, with libFoundation, it 
acts strange. Does anybody know, what I'm missing, or whats wrong with my 
code for libFoundation?

here the code I run with gnustep-base:

#include <Foundation/Foundation.h>

int
main(int argc, const char *argv[])
{
  id pool = [[NSAutoreleasePool alloc] init];

  NSString *GKey = 
@"ABQIAAAAvp3__HwvT3VkixIIbsW0axQuKI_6t1bH2P0vCI_Q8jfpn8qdNBQMnneljxh9czilkau_bYSCXteS_A";

  NSString *Address = @"Potsdamer+Platz+Berlin+Germany";
  NSString *URLString = [NSString 
stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv&key=%@", 
Address, GKey];
  URLString = [URLString 
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
  NSLog(@"URL: %@", URLString);
  NSURL *url = [NSURL URLWithString:URLString];
  NSLog(@"NSURL *url: %@", url);
  NSString *coordinates = [NSString stringWithContentsOfURL:url];
  NSArray *coordItems = [coordinates componentsSeparatedByString:@","];
  NSLog(@"Latitude: %@ Longitude: %@", [coordItems objectAtIndex:2], 
[coordItems objectAtIndex:3]);
  NSString *GeoCacheURL = [NSString 
stringWithFormat:@"http://www.geocaching.com/seek/nearest.aspx?origin_lat=%@&origin_long=%@",

[coordItems objectAtIndex:2], [coordItems objectAtIndex:3]];
  NSLog(@"NewURL: %@", GeoCacheURL);
  [pool release];

  return 0;
}

and here the output:

http://www.geocaching.com/seek/nearest.aspx?origin_lat=52.509328&origin_long=13.375837



here the code I run with libFoundation:
#include <Foundation/Foundation.h>
#include <NGExtensions/NSString+misc.h>

int
main(int argc, char **argv, char **envp)
{
  [NSProcessInfo initializeWithArguments:argv count: argc environment: 
envp];
  id pool = [[NSAutoreleasePool alloc] init];

  NSString *GKey = 
@"ABQIAAAAvp3__HwvT3VkixIIbsW0axQuKI_6t1bH2P0vCI_Q8jfpn8qdNBQMnneljxh9czilkau_bYSCXteS_A";

  NSString *Address = @"Potsdamer+Platz+Berlin+Germany";
  NSString *URLString = [NSString 
stringWithFormat:@"maps.google.com:80/maps/geo?q=%@&output=csv&key=%@", 
Address, GKey];
//  URLString = [URLString 
stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
  URLString = [URLString stringByEscapingURL];
  URLString = [@"http://" stringByAppendingString:URLString];
  NSLog(@"URL: %@", URLString);
  NSURL *url = [NSURL URLWithString:URLString];
  NSLog(@"NSURL *url: %@", url);
  NSString *coordinates = [NSString stringWithContentsOfURL:url];
  NSArray *coordItems = [coordinates componentsSeparatedByString:@","];
  NSLog(@"Latitude: %@ Longitude: %@", [coordItems objectAtIndex:2], 
[coordItems objectAtIndex:3]);
  NSString *GeoCacheURL = [NSString 
stringWithFormat:@"http://www.geocaching.com/seek/nearest.aspx?origin_lat=%@&origin_long=%@",

[coordItems objectAtIndex:2], [coordItems objectAtIndex:3]];
  NSLog(@"NewURL: %@", GeoCacheURL);
  [pool release];

  return 0;
}

and the corresponding output:

Uncatched Objective-C exception:
exceptionClass <class RangeException>
Reason: objectAtIndex: in NSArray
UserInfo: {
    index = 3;
    size = 1;
}

libFoundation adds a :80 to the end of the URL, I wonder why, and whether 
this is the problem?

kind regards
Sebastian
