I am developing an application with REST full web service .Now i have some problem in this case ,ie string sent to a servier using put method. I am using the following code.
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"http://176.31.113.164/app/profil/add"]];
[request setValue:#"Digest adf#email.com:test" forHTTPHeaderField:#"Authorization"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"content-type"];
//[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSDictionary *dic=[[NSDictionary alloc]init ];
dic=[NSDictionary dictionaryWithObjectsAndKeys:#"15",#"#idUsers",#"17",#"#idProfils",#"ddduu",#"address",#"ddd",#"city",#"ddd",#"country",#"adf#email.com <mailto:adf#email.com>",#"email",#"1",#"enabled",#"fff55",#"firstName",#"fffdd3",#"lastName",#"fffffcc",#"nickName",#"test",#"password",#"0",#"phone",#"0",#"postCode",#"ROLE_USER",#"role", nil];
NSString *jsonString = [jsonWriter stringWithObject:dic];
NSData *postData= [jsonString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
[request setHTTPBody:postData];
[request setHTTPMethod:#"PUT"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
NSURLConnection* _loginConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (_loginConnection==NULL)
{
NSLog(#"Problem");
}
[_loginConnection start];
The received data is handled as this:
NSString* tempString =[NSJSONSerialization
JSONObjectWithData:_receivedData
options:kNilOptions
error:&error];
You can use ASIHTTP wrapper class to perform REST operations in your iOS application.
Download the latest ASIHTTP from here.

I am trying to make POST request using NSURLConnection sendSynchronousRequest. It works great when I run app on Simulator, but on real device I got timeout error (NSURLErrorDomain" - code: -1001), my server works ok
My code:
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:30];
[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 = nil;
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
Why I see timeout? and it is only on device?
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 am sending two array and multiple value throw json but when i send this i am getting success code 200 and its response showing access denied pls any one give me right way to solve it **

Wanted to see your php code as well..Anyways please check whether the following example helps you out... Here I am not sending any dictionary values, adjust the code to your requirement :)
NSString *jsonRequest = #"{\"username\":\"user\",\"password\":\"pwd\"}";
NSLog(#"Request: %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"http://xxxyyyzzzz.php"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[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];
[NSURLConnection connectionWithRequest:[request autorelease] delegate:self];
try this code
NSDictionary *dict = [NSDictionary
dictionaryWithObjectsAndKeys:oneRowColumn,#"oneRowCols",memberTid,#"table_title_id",totalRowStr,#"totRow",rowandColumn,#"tempColName",tableOptIdArray ,#"tempOptid",companyId,#"companyid",#"savecolumniphone",#"tag",nil];
NSString *jsonRequest = [dict JSONRepresentation];
NSURL *url = [NSURL URLWithString:#"http://xxxyyyzzzz.php"];
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];
connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];

Dilshand's answer is ok , but you can use ASIFormDataRequest for ease. like follow
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setRequestMethod:#"POST"];
[request setPostValue:mobileApplicationId forKey:#"mobileApplicationId"];
[request setPostValue:mobileApplicationVersion forKey:#"mobileApplicationVersion"];
[request setPostValue:userID forKey:#"userId"];
[request setPostValue:pass forKey:#"password"];
[request setValidatesSecureCertificate:NO];
[request setDelegate:self];
[request setTimeOutSeconds:60];
[request startAsynchronous];

I make iphone application, post parametes to JSP (test.jsp in server) from iphone. The following is my codes:
NSData *postData = [#"&test=123&field=456" dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
// Init and set fields of the URLRequest
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
[request setURL:[NSURL URLWithString:[NSString stringWithString:#"http://mydomain.com/test.jsp"]]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:postData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
// Return data of the request
NSData *receivedData = [[NSMutableData data] retain];
}
[request release];
But my problem is: I can not get return result from JSP server.
How I can setup in JSP to get return result in iPhone? and in iPhone too?
Thank all
Do you implement this in your delegate:
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
Data won't just magically appear in your receivedData instance. You need to implement the delegate methods for NSURLConnection. Take a look at Apple's documentation on how to this all properly.
