I have one text field I need to send two data's to API.
NSString *post =[NSString stringWithFormat:#"val1=%#,val2=%#",[[NSUserDefaults standardUserDefaults] objectForKey:#"val1"],val2];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://api.test.com/send"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(#"log%#",str);
}
I need to send only raw data to API this is my code.Please check and let me know thanks

NSData *postData = [someStringToPost dataUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:someURLString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:[NSString stringWithFormat:#"%d", postData.length] forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error = nil;
NSHTTPURLResponse *response = nil;
NSData *retData = [NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&error];
if (error)
{
//error
}
else
{
//no error
}
Try this

Have you tried converting it to NSData and sending that?
Here's the conversion:
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:array];
That will give you the data in bytes, then just pass it in with the normal networking function calls.

How to post JSON data to server in iOS?

I am trying to send JSON data to server, but it is not go to server. I am getting nil data to print from server side but no use . Here I am using code for post data to server
NSError *error;
NSDictionary *dict=#{
#"allgroups": #{
#"groupname": #"prasad",
#"group_id":#"26",
#"user_id":#"8",
#"contacts": #[contactsArray]
}
};
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:dict
options:NSJSONWritingPrettyPrinted
error:&error];
NSString *saveString = [[NSString alloc] initWithData:jsonData
encoding:NSUTF8StringEncoding];
NSString *myRequestString = [NSString stringWithFormat:#"%#",saveString];
NSData *myRequestData = [NSData dataWithBytes: [myRequestString UTF8String] length: [myRequestString length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: [NSString stringWithFormat:#"http://example.php"]]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setHTTPMethod: #"POST"];
//post section
[request setHTTPBody: myRequestData];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

NSMutableArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];
NSLog(#"String value is:: %#",returnString);
please help me.thanks in advance
Following function is working for me .You can use it:
-(NSMutableArray*)Post_method:(NSString*)post_string posturl:(NSString *)post_url
{
NSString *post =post_string;
NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:#"%#%#",kBaseURL,post_url]];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error;
NSURLResponse *response;
NSData *responseData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString* aStr = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ;
SBJSON *json=[[SBJSON alloc]init];
NSMutableArray *resultp=[json objectWithString:aStr];
//NSLog(#"result %# ",resultp);
return results;
}
And call this function as:
[self Post_method:[NSString stringWithFormat:#"%#",jsonString] posturl:#""];
You should directly pass your jsonData to NSMutableURLRequest like this:
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&error];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: [NSString stringWithFormat:#"http://example.php"]]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setHTTPMethod: #"POST"];
[request setHTTPBody:jsonData];

Unable to post data to WCF service from iPhone

I am trying to post data to WCF service from iPhone Application but somehow service doesn't seems to be call through the iPhone. I received a Status Code = 999.
NSString *urlString = #"http://192.168.1.192/MSservice/SecureRegistration";
NSURL *URL = [NSURL URLWithString:
[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *postData = [bodyData stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
[request setValue:#"gzip" forHTTPHeaderField:#"Accept-Encoding"];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:[postData dataUsingEncoding:NSUTF8StringEncoding]];
NSError *errorReturned = nil;
NSURLResponse *theResponse =[[NSURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
if (errorReturned)
{
NSLog(#"Error %#", errorReturned.localizedDescription);
}
else
{
NSLog(#"Data %#", data);
NSString *responseString=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Response %#", responseString);
}

unsupported URL error code -1002

Hi Please help me how to prepare NSMutableURLRequest for below api
URL : www.XXXXXXXX.com/api.php
For Login :-
www.XXXXXXXXXXXX.com/api.php?task=login
POST Data :-
"email" => User's email
"pw" => User's Password
json response: session id on successful login
Am trying like this.
NSMutableURLRequest *request;
request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"www.XXXXXXXX.com/api.php?task=login"]];
[request setHTTPMethod:#"POST"];
NSString *postString =#"email=xxxxxxxx#gmail.com&pw=1234";
[request setValue:[NSString
stringWithFormat:#"%d", [postString length]] forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:[postString
dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
One reason could be that you forgot to add the "http:" scheme:
[NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://www.XXXXXXXX.com/api.php?task=login]];
HERE --^
Note also that the correct way to set body data and in particular the length is
NSString *postString =#"email=xxxxxxxx#gmail.com&pw=1234";
NSData *postData = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setValue:[NSString stringWithFormat:#"%d", [postData length]]
forHTTPHeaderField:#"Content-length"];
[request setHTTPBody:postData];
because the length of the UTF-8 encoded data can be different from the (Unicode) string length.
I ran into this error when I specified my base URL with a variable that accidentally contained a new line.
Try this:
NSError *error;
NSString *jsonString;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonData1
options:0 error:&error];
if (!jsonData) {
NSLog(#"Got an error: %#", error);
} else {
jsonString= [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
}
NSData *postData = [[[NSString alloc] initWithFormat:#"method=methodName&email=%#&password=%#", user_name, pass_word] dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%ld",[postData length]];
jsonData=[jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:URL]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"\"Accept\""];
[request setValue:#"application/json" forHTTPHeaderField:#"\"Content-Type\""];
[request setValue:postLength forHTTPHeaderField:#"\"Content-Length\""];
[request setValue:#"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:jsonData];
NSError *requestError = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response
error:&requestError];
if ([response statusCode] >= 200 && [response statusCode] < 300) {
NSError *serializeError = nil;
NSString* newStr = [NSString stringWithUTF8String:[urlData bytes]];
NSDictionary *jsonData = [NSJSONSerialization
JSONObjectWithData:urlData
options:NSJSONReadingAllowFragments
error:&serializeError];
NSLog(#"recdata %#",jsonData);
}
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection)
{
NSLog(#"theConnection is succesful");
}
[connection start];

Sending to PHP file on server using Post in iOS application

Simple POST message to server

I want to send a simple message(NSString) to my php script. I am trying to do a POST request. I am unable to do this and I am not sure what I am doing wrong. Can someone tell me my mistake?
Thank you!
PHP Code
<?php
if($_POST['error'])
{
$date= time();
$error=$_POST['error'];
$message=$date." ".$error;
echo $message;
//Rest of code just writes to a log file
?>
---------------------
NSString *post =[[NSString alloc] initWithFormat:#"error=%#",serverError];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://mysite.com/error.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSLog(#"responseData is %#", responseData);
Try this
NSString *post = [NSString stringWithFormat:#"error=%#", serverError];
rather than
NSString *post = [[NSString alloc] initWithFormat:#"error=%#", serverError];
