Strange prb wiith NSUrlRequest - objective-c

I try to send a large string 30k with NSURLRequest via NSSession downloadTaskWithRequest but all datas are not sent ?!
-(NSURLRequest*) GetMySQLCommand
{
NSString *StringToSend = [NSString stringWithFormat: POST_SEND_SQL, _myHashIdstr, _mySQLType, _mySQLStringCommand, _mySQLProcReturn, _myStrId];
NSLog(#"-----> Post Data = %#", StringToSend);
NSData *postData = [StringToSend dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%llu", (unsigned long long)[postData length]];
NSLog(#"-----> Post Data to send = %#", postLength);
_myRequest = [[NSMutableURLRequest alloc] init];
[_myRequest setHTTPMethod:#"POST"];
[_myRequest setURL:[NSURL URLWithString:_myIpAdress0]];
[_myRequest setValue:postLength forHTTPHeaderField:#"Content-Length"];
[_myRequest setValue:#"text/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[_myRequest setHTTPBody:postData];
return _myRequest;

HTTP Post Request with Body Contents fails

i'm trying to send an HTTP post request from my objective-c application to my server. i tried many different things, but i can't get the request to work with the content on request body. With the parameters on the url it work just fine, but i need to send a string with reserved characters.
This is my class responsible for the request:
#import "CLPUtilRequest.h"
static NSString *baseURL = #"http://localhost:8080/cl-mobile";
#implementation CLPUtilRequest
//Parameteres on the URL (working!!)
+ (NSData *) makeHttpRequest:(NSString *)url {
//Set info for webservice
NSString *urlString = baseURL;
urlString = [urlString stringByAppendingString:url];
NSURL *resquestUrl = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:resquestUrl];
[request setHTTPMethod: #"POST"];
[request setValue:#"application/http" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
//Call the webservice
NSError *errorReturned = nil;
NSHTTPURLResponse *theResponse =[[NSHTTPURLResponse alloc]init];
return [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
}
//Parameteres on the bodt (not working!!)
+ (NSData *) makeHttpRequestContentOnBody:(NSString *)url withContent:(NSString *)content {
NSData *postData = [content dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *errorReturned = nil;
NSHTTPURLResponse *theResponse =[[NSHTTPURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
return data;
}
#end
And this is where i call the request.
NSString *contentString = #"chaveUsuarioEmpresa=";
contentString = [contentString stringByAppendingString:appDelegate.clinica.chave];
contentString = [contentString stringByAppendingString:#"&chaveAgendamento="];
contentString = [contentString stringByAppendingString:appDelegate.agendamento.chave];
contentString = [contentString stringByAppendingString:#"&anamnese="];
contentString = [contentString stringByAppendingString:self.texto.text];
NSData *dataResponse = [CLPUtilRequest makeHttpRequestContentOnBody:#"/agendamento/anamnese/save" withContent:contentString];
After calling the request, my errorReturned gives me the following (debugging): NSURLError * domain: #"NSURLErrorDomain" - code: -1002
I tried to do as described in this link (but didn`t make it): Sending an HTTP POST request on iOS
Thanks in advance!
according to Apple's Error Codes -1002 is the code for an unsupported url. and actually you are sending it to /agendamento/anamnese/save, as you don't prepend baseURL as you do in the other call
+ (NSData *) makeHttpRequest:(NSString *)url {
//Set info for webservice
NSString *urlString = baseURL;
urlString = [urlString stringByAppendingString:url];
NSURL *resquestUrl = [NSURL URLWithString:urlString];
while in makeHttpRequestContentOnBody:withContent: you use the unchanged passed in url string /agendamento/anamnese/save
Try
+ (NSData *) makeHttpRequestContentOnBody:(NSString *)url withContent:(NSString *)content
{
NSData *postData = [content dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSString *urlString = baseURL;
urlString = [urlString stringByAppendingString:url];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *errorReturned = nil;
NSHTTPURLResponse *theResponse =[[NSHTTPURLResponse alloc]init];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&errorReturned];
return data;
}

post request to server does not send the content of textfields?

I'm trying to send the content of my textfields firstname and lastname with my button sendpost to my php server. Once I run my app and fill my textfields with some random text and press send, I receive an e-mail on my server but there is no content.
(void) sendAction{
NSError *error = nil;
NSString *postparams = [NSString stringWithFormat:#"info=%#_%#",firstname.text,lastname.text];
NSData * postdata = [postparams dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString * postlength= [NSString stringWithFormat:#"%d",[postdata length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setURL:[NSURL URLWithString:#"http://faketest.com/test/mail.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:postlength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:postdata];
NSData * rawdata = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
NSString *rawdatastring =[[NSString alloc]initWithData:rawdata encoding:NSUTF8StringEncoding];
NSLog(#"%#",rawdatastring);
}
I believe it may be because you're using a "Current-Type" header, instead of the usual "Content-Type" header. Try the following and see if it solves the problem:
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];

Sending JSON through POST not working - Objective C

I am sending a JSON string to our server using the POST method. What should happen is that it should return a response showing "Array(JSON String) Array(JSON String)". The response contains two arrays: The first array is populated if I used the POST method, while the second array is populated if I use the GET method. I tried sending the JSON through GET method and indeed, the second array was populated. However, when I tried to send JSON through POST method, both arrays are returned empty.
Here is the code I used:
NSData *requestData = [NSJSONSerialization dataWithJSONObject:sqlArray options:NSJSONWritingPrettyPrinted error:&error];
NSURL *url = [NSURL URLWithString:#"http://myurl/xmlrpc/imwebsrvcjson.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:requestData];
NSData *result =[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *returnString = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
if (error == nil){
NSLog(#"The Result string: %#", returnString);
}
Can you tell me what is wrong with my code?
Here's what I do (please note that the JSON going to my server needs to be a dictionary with one value (another dictionary) for key = question..i.e. {:question => { dictionary } } ):
NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:#"StoreNickName"],
[[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:#"user_question"], nil];
NSArray *keys = [NSArray arrayWithObjects:#"nick_name", #"UDID", #"user_question", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:#"question"];
NSString *jsonRequest = [jsonDict JSONRepresentation];
NSLog(#"jsonRequest is %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"https://xxxxxxx.com/questions"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (connection) {
receivedData = [[NSMutableData data] retain];
}
The receivedData is then handled by:
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [jsonString JSONValue];
NSDictionary *question = [jsonDict objectForKey:#"question"];
This isn't 100% clear and will take some re-reading, but everything should be here to get you started. And from what I can tell, this is asynchronous. My UI is not locked up while these calls are made. Hope that helps.

NSURLConnection freeze

I'm trying to send JSON post using NSURLConnection:
NSURL *url = [NSURL URLWithString:urlStr];
NSString *jsonPostBody = [NSString stringWithFormat:#"{\"user\":""\"%#\""",\"pass\":""\"%#\""",\"listades\":\"\"}",
[username stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
[password stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSLog(#"JSNON BODY:%#", jsonPostBody);
NSData *postData = [jsonPostBody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:10.0];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:postData];
[request setTimeoutInterval:2.0];
NSString* postDataLengthString = [[NSString alloc] initWithFormat:#"%d", [postData length]];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:postDataLengthString forHTTPHeaderField:#"Content-Length"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
App execution gets freeze when it reaches connection command, despite timeout.
I'm stucked in this issue and I can not find a solution.
Many thanks

}
It's freezing your app because you have passed YES into startImmediately. This will freeze the app until request is finished.
You need to use something like connectionWithRequest:delegate: - this will run the request in the background and tell you when it's done.
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];

Objective-C &JSONKit POST issue

I'm trying to post to a rails backend from Objective-C and JSONKit and am having difficulty getting my results published. I keep getting back a null recordset from my server.
[dictionary setValue:(#"bar") forKey:#"foo"];
NSString *JSON = [dictionary JSONString];
NSData *theData = [JSON dataUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString: myUrl];
NSString *postLength = [NSString stringWithFormat:#"%d", [theData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
NSError *error = NULL;
NSURLResponse *response = nil;
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json-rpc" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:theData];
NSData *result = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response error:&error];
NSString *resultString = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
NSLog(resultString);
Is there something I'm missing? the JSON seems to be serializing correctly
{"foo":"bar"}
Any help would be greatly appreciated.
Thanks!
Just changed the setValue from json-rpc to json and it worked like a champ.
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
**[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];**
[request setCachePolicy:NSURLRequestReloadIgnoringCacheData];
[request setHTTPBody:theData];
