I am having 1 webservice in php which is having browser url mentioned bel :
http:Domain/webservice/ACTEC_WebService.php?lastupdate=2012-09-01 01:00:00
Now when I try to fetch url in my iphone app, it is taking this url:
http://Domain/webservice/ACTEC_WebService.php?lastupdate=2012-09-01%2001:00:00
This is creating problem.
i have used this code for fetching data from my url.
SBJSON *json = [SBJSON new];
json.humanReadable = YES;
responseData = [[NSMutableData data] retain];
NSString *service = @"";
NSString *str;
str = @"LastUpdated";
NSString *requestString = [NSString stringWithFormat:@"{\"LastUpdated\":\"%@\"}",str];
// [[NSUserDefaults standardUserDefaults] setValue:nil forKey:@"WRONGANSWER"];
NSLog(@"request string:%@",requestString);
NSData *requestData = [NSData dataWithBytes: [requestString UTF8String] length: [requestString length]];
NSString *fileLoc = [[NSBundle mainBundle] pathForResource:@"URLName" ofType:@"plist"];
NSDictionary *fileContents = [[NSDictionary alloc] initWithContentsOfFile:fileLoc];
NSString *urlLoc = [fileContents objectForKey:@"URL"];
//urlLoc = [urlLoc stringByAppendingString:service];
NSLog(@"URL : %@",urlLoc);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:
[NSURL URLWithString:urlLoc]];
NSString *postLength = [NSString stringWithFormat:@"%d", [requestData length]];
[request setHTTPMethod: @"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:requestData];
NSError *respError = nil;
NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: &respError ];
NSString *responseString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
NSLog(@"Resp : %@",responseString);
if (respError)
{
// NSString *msg = [NSString stringWithFormat:@"Connection failed! Error - %@ %@",
// [respError localizedDescription],
// [[respError userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"ACTEC"
message:@"check your network connection" delegate:self cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alertView show];
[alertView release];
}
else
{
......
}
here,i am getting null response as url is getting decoded...How can I make this solved... Help me out. Thanks in advance.
NSString *urlLoc = [[fileContents objectForKey:@"URL"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableData *postData = [NSMutableData data];
NSMutableURLRequest *urlRequest;
[postData appendData: [[NSString stringWithFormat: @"add your data which you want to send"] dataUsingEncoding: NSUTF8StringEncoding]];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
urlRequest = [[NSMutableURLRequest alloc] init];
[urlRequest setURL:[NSURL URLWithString:urlLoc]];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
[urlRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[urlRequest setHTTPBody:postData];
NSString *temp = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
NSLog(@"\n\nurl =%@ \n posted data =>%@",urlLoc, temp);
check nslog. that which data u send to service.
NSData *response = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSLog(@"json_string >> %@",json_string);
Maybe this will help you.
hey dear just for an another example i just post my this code..
first Create new SBJSON parser object
SBJSON *parser = [[SBJSON alloc] init];
NSURLRequest *request = [NSURLRequest requestWithURL:
[NSURL URLWithString:@"http:Domain/webservice/ACTEC_WebService.php?lastupdate=2012-09-01%2001:00:00"]];
Perform request and get JSON back as a NSData object
NSData *response = [NSURLConnection sendSynchronousRequest:request
returningResponse:nil error:nil];
Get JSON as a NSString from NSData response
NSString *json_string = [[NSString alloc]
initWithData:response encoding:NSUTF8StringEncoding];
Parse the JSON response into an object Here we're using NSArray since we're parsing an array of JSON status objects
NSArray *statuses = [parser objectWithString:json_string error:nil]
And in statuses array you have all the data you need.
i hope this help you...
