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!

Is it possible to check the data which I have sent in HTTP POST request, by logging the request in XCode.
Here is my code:
NSString *post = [NSString stringWithFormat:#"Firstname=%#&Lastname=%#&Email=%#",firstName,lastName,emailId];
NSLog(#"%#", post);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"http://www.abcde.com/xyz/login.aspx"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
**NSLog(#"%#", request );**
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
I am logging the request as shown above in Bold. But here I am able to see only my Url and not any post data.
If it is not possible to see data here where can I see the data sent in http request.
If you want just check what data are you sending then I suggest you to use this awesome tool http://www.charlesproxy.com. It's very simple and powerful.
Just run Charles and do your request via simulator.
I want to build up a login page and the values of this page i want to submit in server through a specific link. can any one send the code that how i will send the data into server?
Here's an example using NSURLConnection to send POST parameters:
// Note that the URL is the "action" URL parameter from the form.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL #"http://www.whereq.com:8079/answer.m"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
//this is hard coded based on your suggested values, obviously you'd probably need to make this more dynamic based on your application's specific data to send
NSString *postString = #"paperid=6&q77=2&q80=blah";
NSData *data = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
[request setValue:[NSString stringWithFormat:#"%u", [data length]] forHTTPHeaderField:#"Content-Length"];
[NSURLConnection connectionWithRequest:request delegate:self];
Im trying to send a data or what it seems to a form that is on the website, the action is freecontactformprocess.php and my code goes like this,
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://www.irabwah.com/freecontactformprocess.php"]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
NSString *postString = [NSString stringWithFormat:#"Full_Name=%#&Email_Address=%#&Telephone_Number=%#&Your_Message=%#&AntiSpam=25",_fNameLabel.text, _emailLabel.text,_phoneLabel.text, _commentText.text];
NSData *data = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
[request setValue:[NSString stringWithFormat:#"%u", [data length]] forHTTPHeaderField:#"Content-Length"];
NSURLConnection *conn = [NSURLConnection connectionWithRequest:request delegate:self];
if(conn){
NSLog("Successfull!!");
}
the purpose of this form is to send an email into my account which I integrated into the form on installation of this plugin, but the thing is I doesn't seems to get a the email when I run my test app, and when Im inputing values I don't include spaces yet.
The form looks like this,
I've sent this URL via post:
https://api.instagram.com/v1/users/XXX/relationship?action=unfollow&access_token=YYY
XXX is a valid userid, I've checked that multiple times. The token (YYY) is correct too.
This is the response:
{"meta":{"error_type":"APIInvalidParametersError","code":400,"error_message":"please supply action=approve,ignore,follow,block,unblock,unfollow"}}
I've tried action=follow and action=unfollow. Is it possible, that this is a bug? Where can I report it?
Instagram API Documentation: http://instagram.com/developer/endpoints/relationships/
The problem is that you are not sending the action as postdata. I had the exact problem just yesterday.
The access_token should be sent in the url, but the action=follow should be in the postdata of the request!
NSString *initialURL = [NSString stringWithFormat:#"https://api.instagram.com/v1/users/USER_ID/relationship?access_token=ACCESS TOKEN"];
NSURL *url=[NSURL URLWithString:initialURL];
NSString *key = [NSString stringWithFormat:#"action=follow"];
NSData *mastData = [key dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *mastLength = [NSString stringWithFormat:#"%d",[mastData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:mastLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:mastData];
NSURLConnection *con=[[NSURLConnection alloc]initWithRequest:request delegate:self];
[con start];
Also make sure to use proper scope while authenticating.
Add scope=like+comments+relationships in that authentication URL.
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)
