friend
I am trying so much but I didn't get any solution
if he or she enter their username and password then i want cheek there value from webserver database.
If his username and password is much there only after then he will use the application .
other then that he doesn't have permission use this application.
You can try this code:-
NSString *post = [NSString stringWithFormat:#"Loginkey=%#&Password=%#&DeviceCode=%#&Firmware=%#&IMEI=%#",txtUserName.text,txtPassword.text,model,sysver,udid];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSLog(#"%#",postLength);
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://191.16.0.6:91/JourneyMapperAPI?RequestType=Login"]]; //add your web service url here
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
Take a look at ASIHTTPRequest, which includes simple methods for basic HTTP authentication.

I have an webservices url which appends with password. When I run the application by giving correct password, the application is running and at the same time when I run the app with wrong credentials. the app is running, I didn't have an idea to get rid out of the issue. My code is here:
NSString *post =[[NSString alloc] initWithFormat:#"password=%#",[password text]];
NSLog(#"PostData: %#",post);
NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:#"http://myexample.com/Accountservice/Secure/ValidateAccess?password=abcd&type=1"]];
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];
NSURLRequest *request1 = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:post] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request1 delegate:self startImmediately:YES];
if(!connection){
NSLog(#"connection failed");
}
else{
NSLog(#"connection succeeded");
}
If I gave 'abcd' as password connection is successfully is displaying. If I gave wrong password connection successfully is displaying. How can I solve the issue? If I gave wrong password need to display an alert.
This control structure here is the problem:
if(!connection){
NSLog(#"connection failed");
}
else {
NSLog(#"connection succeeded");
}
This doesn't check for a bad connection, this checks whether or not the connection object is equal to 0 (nil). Obviously, having initialized it on the line above, the else statement will always log, giving you the false impression that your connection had succeeded. You should become the connection's delegate, and respond to the appropriate delegate methods instead.
The issue may be with the url you are using
Fire the url in the browser and see what it returnes
try add the url params with single quotes accesscode='abcd'
It is not a good practice to pass the credentials via this way.
You could use POST method with some valid encryption to prevent the security issues that can occur
SOLUTION
Try this
NSString *urlString=#"http://myexample.com/Accountservice/Secure/ValidateAccess?";
self.responseData = [NSMutableData data];
NSString *post =[NSString stringWithFormat:#"username=%#&password=%#",userNameTextField.text,passwordTextField.text];
NSData *postData=[post dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[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];
NSURLConnection *connection0= [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection0 start];
I have the following details, for get the data from server. What is the use of methodIdentifier and web service name ?
{"zip":"12345","methodIdentifier":"s_dealer"}
url:- http://xxxxxxxxxxxxxxx.com/api.php
method: post
web service name: s_dealer
response : {"success":"0","dealer":[info...]}
I don't know how to send zip number "12345" with the url. Please direct me on right direction. I use the following.
-(void)IconClicked:(NSString *)zipNumber
{
NSString *post = [NSString stringWithFormat:#"&zipNumber=%#",zipNumber];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://xxxxxxxxxxxxxxxxxxx.com/api.php"]]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if(conn)
{
NSLog(#"Connection Successful");
}
else
{
NSLog(#"Connection could not be made");
}
receivedData = [[NSMutableData alloc]init];
}
when i print the response in console :\"Unexpected end of string\"
Without knowing more about the API, I can't be certain about your requirements, but it seems that the server is expecting the request to contain JSON. The way you currently are creating the body for the request is using standard POST variables.
Have you tried changing:
NSString *post = [NSString stringWithFormat:#"&zipNumber=%#",zipNumber];
to:
NSString *post = [NSString stringWithFormat:#"{\"zip\":\"%#\",\"methodIdentifier\":\"s_dealer\"}",zipNumber];
Regarding your other questions, I'm guessing that there is a single URL for the API. The methodidentifier is used by the server in order to determine which server method(s) to run.
You get this error because you do not get a json as a response, but an error from Apache (or whatever), that has different structure, and json cannot parse it. Try my method to initiate the connection, in order to gain a successful one.
Declare a NSURLConnection property and synthesize it. Now:
NSString *post = [NSString stringWithFormat:#"zipNumber=%#",zipNumber];
NSString *toServer = [NSString stringWithString:#"your server with the last slash character"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#api.php?", toServer]];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *urlRequest = [[[NSMutableURLRequest alloc] init] autorelease];
[urlRequest setURL:url];
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setValue:postLength forHTTPHeaderField:#"Content-Length"];
[urlRequest setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[urlRequest setValue:#"utf-8" forHTTPHeaderField:#"charset"];
[urlRequest setHTTPBody:postData];
[urlRequest setTimeoutInterval:30];
NSURLConnection *tmpConn = [[[NSURLConnection alloc] initWithRequest:urlRequest delegate:self] autorelease];
self.yourConnectionProperty = tmpConn;
Now you work with self.yourConnectionProperty in connection delegates. Cheers!
hey bro check my answer for same problem may help you... You have to use the NSURLConnection Delegates to get the data
Could not make Json Request body from Iphone
Encountered a problem on posting comment back to a comment box.
post not showing up, there is no error or whatsoever to check.
EDIT: Correct Answer
-(void)postToBoard
{
NSString *post = #"author=Jos&email=mail#domain.com.au&url=&comment=score+99.&submit=Post+Comment&comment_post_ID=1&comment_post_ID=1&comment_parent=0";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSString *URLString = #"http://site.com.au/?p=1";
NSURL *postURL = [NSURL URLWithString:URLString];
[request setURL:postURL];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
//[request setValue:#"wp-comments-post.php" forHTTPHeaderField:#"HTTP/1.1"];
[request setHTTPBody:postData];
//self.receivedData = [NSMutableData data];
self.postConnection = [NSURLConnection connectionWithRequest:request delegate:self];
}
This line looks wrong:
[request setValue:#"wp-comments-post.php" forHTTPHeaderField:#"Content-Type"];
It should be:
[request addValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
I'm not sure what you're supposed to do with "wp-comments-post.php", should that perhaps be in the URL instead?
So I am trying to log into my site using an NSMutableURLRequest which presents the credentials via a post. As a noobie, I have some questions about the functionality of this method to make sure I am understanding it.
NSString *post = [NSString stringWithFormat:#"username=%#&password=%#&TARGET=%#",LoginId,LoginPwd,target];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d",[postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setHTTPShouldHandleCookies:YES];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:#"https://somelogin.mycomp.verify.fcc"]]];
//[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Current-Type"];
[request setHTTPBody:postData];
NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
Now this will automatically handle any redirects via the delegate method correct? It will also collect any cookies along the way? Also, should I be using an asynchronous request instead? Thanks!
UPDATE:
So I have deduced that some of the cookies are being ignored by the request and subsequent redirects. Does anyone know why that may be happening?
you can do something like this when logging in synchronously... the code is not perfect, but this is the general idea.
look here for documentation
https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/URLLoadingSystem/Articles/AuthenticationChallenges.html#//apple_ref/doc/uid/TP40009507-SW1
// credentials set here
NSURLCredential *creds = [NSURLCredential credentialWithUser:LoginId password:LoginPwd
persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *protectionedSpace = [[NSURLProtectionSpace alloc]
initWithHost:#"mycomp.verify.fcc"
port:8443
protocol:#"https"
realm:nil
authenticationMethod:nil];
[[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:creds
forProtectionSpace:protectionedSpace];
// removed credentials from line...
NSString *post = [NSString stringWithFormat:#"TARGET=%#",target];
here is a tutorial that does it asynchronously

I am creating an app for the iPhone that fetches a specific page from a website, but to be able to view this site you need to log in with a username and a password.
I've created this code:
NSString *urlAddress = #"http://www.wdg-hamburg.de";
NSURL *url = [NSURL URLWithString:urlAddress];
NSString *post = #"name=loginname&pass=pass&form_id=user_login&op=Anmelden";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod: #"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
[vPlan loadRequest:request];
But I am not logged in at the UIWebView!
I am logging NSHTTPCookieStorage to the console and it shows me the necessary cookie, but I dont get logged in.
Does anybody knows how I can fix that?
Kind regards,
A. Miladinovic
Have you tried setting the cookie in the header?
NSArray* cookies = [NSArray arrayWithObjects: cookie, nil];
NSDictionary * headers = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];
[request setAllHTTPHeaderFields:headers];
