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"];

Any suggestions? The code works perfectly with http but not https://. I wonder if it's the port. The certificate is valid. I get a "server pretending to be another server" error.
NSString *post=[[NSString alloc] initWithFormat:#"strEmail=%#&strPassword=%#", [self.txtUsername text], [self.txtPassword text]];
NSLog(#"PostData%#", post);
// NSURL *url= [NSURL URLWithString:#"http://dipinkrishna.com/jsonlogin.php"]; // does work
NSURL *url= [NSURL URLWithString:#"https://dev.myrdcm.com/felipe.asmx?op=GetSignIn”];// does not work
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu",(unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-fore-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSLog(#"%#",request);
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse * response = nil;
NSData *urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
If you get a "server pretending to be another server" error, then certificate is not valid. I have opened yours url in browser and see that certificate is expired.
Im using codes posted here:
connection release method in connectionDidFinishLoading, causes error
now first execute returns didFail log.
second execute; returns old response data.
albeit my (localhost) server is totally offline.
and cachePolicy is NSURLCacheStorageNotAllowed (check the code on the link I posted above)
NSMutableURLRequest *request=
[NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:3.0f];
the response data seems cached somewhere and still exists.
but if I use NSURLRequestReloadIgnoringLocalAndRemoteCacheData //which is commented as -not implemented-
not returns old cache.
but if so what is the difference between:
NSURLRequestReloadIgnoringLocalAndRemoteCacheData
and
NSURLCacheStorageNotAllowed
what shall I do ?
NSURLCacheStorageNotAllowed refers to NSCachedURLResponse and is an value of enum NSURLCacheStoragePolicy. Since the cache policy of NSMutableURLRequest is also an enum (NSURLRequestCachePolicy) you just pass wrong int to the static method creating NSMutableURLRequest. In this case NSURLCacheStorageNotAllowed is just 2 which equals to NSURLRequestReturnCacheDataElseLoad - and that is why you get old data.
Try This
NSString *Post = [[NSString alloc] initWithFormat:#"Post Parameters"];
NSURL *Url = [NSURL URLWithString:#"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:#"Accept"];
[Request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[Request setHTTPBody:PostData];
NSError *error;
NSURLResponse *response;
NSData *Result = [NSURLConnection sendSynchronousRequest:Request returningResponse:&response error:&error];
if (!Result)
{
NSLog(#"Error");
}
else
{
//Parse the result
}
I'm making a HTTP Post and I would like to know how to convert the response to NSDictionary, or NSArray. Here's my code:
NSString *post = [NSString stringWithFormat: #"SomeData=text", text];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"https://www.my.site/receiver"]];
[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];
EDIT:
The response looks like this after converting like this:
NSString *string = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];

You need to use some kind of parser for that. If the response is in XML you could use NSXMLParser. Here you can find a tutorial on how to use it. The same concept applies for any other kind of data. You have to know beforehand what to expect so you can parse it properly.
I hope it helps
I'm trying to do a simple POST request to a server, with this code:
NSString *post = [[NSString alloc] initWithFormat:#"email=%#&password=%#", self.email.text, ..]; // .. simplified keychainItem
NSData *postEncoded = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%d", [postEncoded length]];
NSURL *url = [NSURL URLWithString:#"http://eng.studev.groept.be/web2.0/a11_web02/testApp.php"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postEncoded];
self.connection = [NSURLConnection connectionWithRequest:request delegate:self];
When debugging on the server, this actually results in a GET request. That explains why I'm getting a PHP error when trying to read $_POST[ ] variables. Bottom line: why isn't the setHTTPMethod: being accepted?
(extra information: when just coding in PHP on the server, use of POST works normally)
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];
