Get the password from the webservices URL and access through that password

cocoa, ios, iphone, objective-c

Solution

In Your case

 NSURL *url=[NSURL URLWithString:[NSString stringWithFormat:@"http://my example.com/Accountservice/Security/ValidateAccess?accesscode=abcd&type=1"]];

You can not pass parameter with `URL in POST` method such like , `....?accesscode=abcd&type=1"`

You can use the following code snippet, as described in this article:

Here, I simple describe how can use of POST method.

1. Set post string with actual username and password.

NSString *post = [NSString stringWithFormat:@"&Username=%@&Password=%@",@"username",@"password"];

2. Encode the post string using `NSASCIIStringEncoding` and also the post string you need to send in NSData format.

NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

You need to send the actual length of your data. Calculate the length of the post string.

NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];

3. Create a Urlrequest with all the properties like `HTTP` method, http header field with length of the post string. Create `URLRequest` object and initialize it.

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

Set the Url for which your going to send the data to that request.

[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.abcde.com/xyz/login.aspx"]]];

Now, set HTTP method (POST or GET). Write this lines as it is in your code.

[request setHTTPMethod:@"POST"];

Set `HTTP` header field with length of the post data.

[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

Also set the Encoded value for HTTP header Field.

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];

Set the `HTTPBody` of the urlrequest with postData.

[request setHTTPBody:postData];

4. Now, create URLConnection object. Initialize it with the URLRequest.

NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];

It returns the initialized url connection and begins to load the data for the url request. You can check that whether you `URL` connection is done properly or not using just if/else statement as below.

if(conn)
{
NSLog(@”Connection Successful”)
}
else
{
NSLog(@”Connection could not be made”);
}

5. To receive the data from the HTTP request , you can use the delegate methods provided by the URLConnection Class Reference. Delegate methods are as below.

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData*)data

Above method is used to receive the data which we get using post method.

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error

This method , you can use to receive the error report in case of connection is not made to server.

- (void)connectionDidFinishLoading:(NSURLConnection *)connection

The above method is used to process the data after connection has made successfully.

Also Refer This and This documentation for `POST` method.

And here is best example with source code of HTTPPost Method.
