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'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!
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 am currently posting json data using an asynchronous NSURLConnection to a ASP.Net WebAPI resource. The connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite: is being called, and the correct amount of data is being written. But the connection:didReceiveResponse:, connection:didReceiveData: or connectionDidFinishLoading: are not being called, but eventually it gives up, and the connection is lost.
I am setting up the connection as follows:
NSURL *url = [[NSURL URLWithString:[Common baseUrl]] URLByAppendingPathComponent:#"api/iCat/wishlists/upload"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.f];
NSString *jsonString = [self generateStrippedJsonForWishlist:wishlist];
NSData *requestData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [jsonString lengthOfBytesUsingEncoding:NSUTF8StringEncoding]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:requestData];
And initiating the connection with:
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
Eventually the request will time out with a "The network connection was lost" error message. To me it seems like the app is never completely finished writing the body of the message.
From the api side, the method is never actually being called (break point is not being hit). But if I send the request with no body, then it does.
I have tested the same call using curl, and it is working as expected:
curl -v -i -X POST -H "Content-Type: application/json" -d '{"CreatedBy":"iPad Simulator","ContactName":"Ddd","ContactEmail":"ddd","Products":[{"ProductId":117,"ProductName":"Internal doors - deco","Specification":""}]}' http://SCMOBILE02:1861/api/iCat/wishlists/upload
Try library https://github.com/AFNetworking/AFNetworking while posting json data.
Can you try the following code below ?
-(void) post
{
NSString * a = #"{company_name : \"com\"}";
NSString * URL = #"yourUrl";
NSString *post = [NSString stringWithFormat: #"%#",a];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu", (unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:URL]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setTimeoutInterval:20.0];
[request setHTTPBody:postData];
[NSURLConnection connectionWithRequest:request delegate:self];
}
In your web api you should have the following class and post method like below
public class company
{
public string company_name { get; set; }
}
// POST api/values
public void Post([FromBody]company value)
{
var t = value;
}
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 developing an ipad app for hospital management were information is filled in the user interface and on the click of a button the data is to be transfered to an external database(which later be viewed)...what are the steps required
You need to set up a webservice (like Saurabh said), for instance a PHP file using an mySQL connection would do fine.
To post the data (unsecured) to the service you can dome something like this:
NSString *post = #"key1=val1&key2=val2";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://www.someurl.com"]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content- Type"];
[request setHTTPBody:postData];
NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
Read the NSURLConnection documentation
