OK, thanks to everyone who contributed, but especially
Michael for the suggestion and the code snippet. If
anyone is curious, here's my code:
NSString *urlString = [NSString
stringWithFormat:@"
http://www.usps.com:80/zip4/zip4_response.jsp?%@";,
[self parameterString]];
NSString *escapedString;
NSURL *aURL;
//NSURL *aURL = [NSURL
URLWithString:@"
http://www.usps.com/zip4/zip4_response.jsp?";];
NSMutableURLRequest *request;
NSLog(urlString);
escapedString = (NSString
*)CFURLCreateStringByAddingPercentEscapes(NULL,
(CFStringRef)urlString, NULL, NULL,
kCFStringEncodingUTF8);
NSLog(@"%@", escapedString);
[escapedString autorelease];
aURL = [NSURL URLWithString:escapedString];
request = [NSMutableURLRequest requestWithURL:aURL
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:@"www.usps.com"
forHTTPHeaderField:@"Host"];
[request addValue:@"text/html"
forHTTPHeaderField:@"Accept"];
[request setHTTPMethod:@"GET"];
connection = [[NSURLConnection alloc]
initWithRequest:request
delegate:self];
([self parameterString] returns a set of parameters
laying out the address I'm interested in.)
Using this code, I was able to get my batch
application to communicate with the USPS website and
retrieve the address data for a given address. Then I
parse the resulting data for the XML tags associated
with the address line, city/state/zip line and county
line.
Michael - you rock!
