che in modalità POST . The object NSMutableURLRequest can be used in either GET that mode POST . . The parameters, however, are formatted as if they were in GET , ie in the sequence nome_campo1=valore1&nome_campo2=valore2&... . Here's a handy snippet to simplify the construction of golf:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | BOOL ) connectionPOST : ( NSURLRequest * ) aRequest - (BOOL) connectionPOST: ( NSURLRequest *) aRequest NSDictionary * ) aDictionary { withParams: ( NSDictionary *) {aDictionary aDictionary count ] > 0 ) { if ([aDictionary count]> 0) { request = [ [ NSMutableURLRequest alloc ] NSMutableURLRequest * request = [[ NSMutableURLRequest alloc] aRequest URL ] ] ; initWithURL: [aRequest URL]]; @ "POST" ] ; [Request setHTTPMethod: @ "POST"]; postString = [ [ NSMutableString alloc ] init ] ; NSMutableString * postString = [[ NSMutableString alloc] init]; allKeys = [ aDictionary allKeys ] ; NSArray * allKeys = [aDictionary allKeys]; int i = 0 ; i < [ allKeys count ] ; i ++ ) { for (int i = 0; i <[allKeys count]; i + +) { key = [ allKeys objectAtIndex : i ] ; NSString * key = [allKeys objectAtIndex: i]; value = [ aDictionary objectForKey : key ] ; NSString * value = [aDictionary objectForKey: key]; ( ( i == 0 ) ? @ "%@=%@" : @ "&%@=%@" ) , key, value ] ; [PostString AppendFormat: ((i == 0)? @ "% @ =% @" @ "&% @ =% @"), Key, value]; } [ postString dataUsingEncoding : NSUTF8StringEncoding ] ] ; [Request setHTTPBody: [postString dataUsingEncoding: NSUTF8StringEncoding]]; connectionWithRequest : request delegate : self ] ; [ NSURLConnection connectionWithRequest: request delegate: self]; ; [PostString release]; ; postString = nil; ; [Request release]; ; request = nil; ; return YES; { Else {} ; return NO; } } |
This method makes it possible to send POST data in the dictionary in the past inputs, more readable and easy:
1 2 3 4 5 6 7 8 9 10 11 | url = [ NSURL URLWithString : @ "http://www.undolog.com" ] ; NSURL * url = [ NSURL URLWithString: @ "http://www.undolog.com"]; request = [ NSURLRequest requestWithURL : url ] ; NSURLRequest * request = [ NSURLRequest requestWithURL: url]; / / Send name = name = Pluto & Goofy params = [ [ NSDictionary alloc ] NSDictionary * params = [[ NSDictionary alloc] initWithObjectsAndKeys: , @ "nome" , @ "Foo", @ "name", , @ "cognome" , nil ] ; @ "Pluto", @ "name", nil]; request withParams : params ] ; [Self connectionPOST: withParams request: params]; ; [Params release]; ; params = nil; |
