When i try to parse special char like "care&love", it just shows "care", the part after "&" truncated How can i make it to show the complete string???
NSURL *url = [NSURL URLWithString:urlStr];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSString *postJson = [NSString stringWithFormat:#"&json=%#", jsonRequest];
NSData *requestData = [postJson dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
Assuming that we are speaking about the value of jsonRequest, you have to URL encode that string before passing it to the postJson, otherwise & is seen as parameter separator.
json=care&love is interpreted as json="care" and love="" by the receiving server.
Url encoding the value will look like json=love%26care and will be decoded by the server as json="love&care"
use stringByAddingPercentEscapesUsingEncoding for escaping, see at: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/stringByAddingPercentEscapesUsingEncoding:
You could use Cocoa's built-in JSON serialization. This would rule out improper string escaping (which is most likely the problem in your current code).
Sample:
NSError* error = nil;
NSDictionary* jsonDict = #{#"json": #"EL- STR 261: HAUL & SPOT"};
NSData* requestData = [NSJSONSerialization dataWithJSONObject:jsonDict options:kNilOptions error:&error];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];

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"];
I'm trying to connect to a server which requires a username and password for Authentication. My code is the following:
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:#"username:password" forHTTPHeaderField:#"Authorization"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
But this does not work, I always get an error message:
title>401 Authorization Required</title>
</head><body>
<h1>Authorization Required</h1>
<p>This server could not verify that you
are authorized to access the document
requested. Either you supplied the wrong
credentials (e.g., bad password), or your
browser doesn't understand how to supply
the credentials required.</p>
When I try to connect to a server which doesn't nee an Authentication this code code works great. So, how to set the username and password correctly?
You should specify the domain of server, try this format:
NSString *authen = [NSString stringWithFormat:#"%#\\%#:%#", m_domain,
m_account, m_password];
[request setValue:authen forHTTPHeaderField:#"Authorization"];
this work for me!
I am using objective C JSON parsing library. My web service returns the JSON response. My parser fails as there is an '\' character in the response string. The response string is like ":\/\/68.491.5.780\/iphoneapplication" but I want to be like "://68.491.5.780/".
My code is here:
NSURL *url=[NSURL URLWithString:
#"http:// url address/Accountservice/Security/ValidateAccess?accesscode=abcd&type=0"];
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];
So how can I remove all back slash "\" in the response receive from web service?
you can replace \ with whitespace like:-
NSString *str =[NSString stringWithFormat:#"%#",#" hi \ hoowoer"];
str = [str stringByReplacingOccurrencesOfString:#"\""
withString:#""];
NSLog(#"==%#",str);
OUTPUT
hi hoowoer
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];
