I am using ASIHTTPRequest in my IOS application to call a wsdl/SOAP web services. my clients use a security mod ( with his ModSecurity / a PHP code).
i am using this :
NSData *xmlData = // I construct the soap message witk soapui
NSURL *url = [NSURL URLWithString:#"https:myUrlWSDL"];
self.currentRequest = [ASIFormDataRequest requestWithURL:url];
[self.currentRequest appendPostData:xmlData];
[self.currentRequest setDelegate:self];
[self.currentRequest startAsynchronous];
But the server send to me the 400 bed request.
How i can, please, do to call my wsdl/web services with all this security mode ? what are the http headers required to call the web services ? thanks for your answers
i have disabled the secure module. now i have this error :
WSDLSOAP-ERROR: Parsing WSDL: Couldn't load from 'http://...?wsdl' : failed to load external entity "http://...?wsdl"
That's how you use ASI to call a secure connection - you're doing everything correctly.
The problem must be in your code that creates the xmlData - what other error information can you get back from your clients server?
You might also need to add more headers to the request (though thats also something that your clients should be able to tell you) - e.g.
[request addRequestHeader:#"Referer" value:#"http://allseeing-i.com/"];

I am wondering what the difference between Get and Post with asihttprequest library..
Is this a GET?
- (IBAction)sendHttpsRequest
{
//Set request address
NSMutableString *databaseURL = [[NSMutableString alloc] initWithString:#"https://142.198.16.35"];
//call ASIHTTP delegates (Used to connect to database)
NSURL *url = [NSURL URLWithString:databaseURL];
//This sets up all other request
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request startAsynchronous];
}
is a post when you try to set elements say within a php document? any examples would be awesome!

An HTTP GET is a request from the client to the server, asking for a resource.
An HTTP POST is an upload of data (form information, image data, whatever) from the client to the server.
What you have there is an HTTP POST.
-EDIT:
Per http://allseeing-i.com/ASIHTTPRequest/:
ASIFormDataRequest
A subclass of ASIHTTPRequest that handles x-www-form-urlencoded and multipart/form-data posts. It makes POSTing data and files easy, but you do not need to add this to your project if you want to manage POST data yourself or don’t need to POST data at all.
My bad, this one was a POST, not a GET. The rest of my answer was valid, though :)
That is a POST request, which is the default for ASIFormDataRequest. The difference is the same as it would be in a normal HTTP request. You can read about that here if you don't already know.
In general, if you are just downloading a web page and do not need to send any variables to the server, a GET request is sufficient. If you want to send variables in your request, often times a POST request is the way to go since it is a bit more secure and less transparent.
I am creating my first iPad app. I have a web application that I would like to authenticate against and pull data from in a RESTful way.
If you open up the URL in the browser (https://myapp.com/auth/login), you will get a form to enter your username and password. I was thinking I could set the login credentials in the post data of the request and submit the data.
The site uses HTTPS for login so that credentials aren't passed in plain text over the internet.
How can I make a secure HTTPS connection to pass credentials? Will this remember that I am logged in for future requests? What is the best way to do this?
Further update, October 2013
Although at the time I wrote this answer, ASIHTTPRequest was maintained a widely supported, this is no longer the case. It is not recommended for new projects - instead use NSURLConnection directly, or use AFNetworking.
With AFNetworking, there is a [httpClient setAuthorizationHeaderWithUsername:username password:password]; method for http authentication, and create a POST style form is equally easy - see AFNetworking Post Request for that.
Original answer:
A lot of people use the ASIHTTPRequest class to deal with http & https on the iPhone/iPad, as it has a lot of useful features that are difficult or time consuming to achieve with the built in classes:
http://allseeing-i.com/ASIHTTPRequest/
Starting at the simplest level you'd start with something like:
NSURL *url = [NSURL URLWithString:#"http://allseeing-i.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
NSLog(#"response = %#", response);
}
If you're using HTTP authentication, ASIHTTPRequest will automatically prompt the user for the username and password.
IF you're using some other form of authentication you probably need to request the username and password from the user yourself, and submit them as a POST value or a custom http header, and then the response may either include a token in a JSON or XML response, or it could set a cookie.
If you add more details as to how the authentication scheme works I can be a bit more specific.
Update
Based on the update, to emulate a POST form you'd just need to add lines like:
[request addPostValue:usernameString forKey:#"username"];
[request addPostValue:passwordString forKey:#"password"];
You will also need to change the way you create the request, instead of:
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
do:
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
(I also forget to mention it above, there's code I put earlier is using a synchronous request, so you'd want to replace it with an asynchronous one to avoid blocking the UI once you'd proved it was working.)
There's a JSON framework for the iphone here:
http://code.google.com/p/json-framework/
which works well for me and is simple to use with ASIHTTPRequest.
I want to connect to a server using HTTP, send a string to it and recieve the response string from the server. Any ideas about how to connect to server by the url, send and recieve message from it?
// create the request
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.apple.com/"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
// Create the NSMutableData that will hold
// the received data
// receivedData is declared as a method instance elsewhere
receivedData=[[NSMutableData data] retain];
} else {
// inform the user that the download could not be made
}
See this resource.
I suggest using the excellent ASIHTTPRequest source from All-Seeing Interactive: http://allseeing-i.com/ASIHTTPRequest. I'm doing this, and so are several released iPhone apps, so you can be sure the code is pretty solid.
This is a wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications.
It is suitable for performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.
You can connect to a server, send a string, and receive the response using the NSMutableURLRequest and NSURLConnection classes. A good place to start is the Introduction to the URL Loading System.
Hi I am currently designing my second iphone app, and having a small issue.
I have the location code working correctly but I have no idea how to send the label with the location info to my server.
I was wondering and hoping someone might be able to help.
Thanks
Russell
That would depend entirely on what your PHP script expects to receive. Your most obvious choices would be to put the coordinates in the query string or in a POST request.
Use ASIHTTPRequest for http requests. http://allseeing-i.com/ASIHTTPRequest/
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:#"Josh" forKey:#"first_name"];
[request setPostValue:#"Highland" forKey:#"last_name"];
[request start];
I am searching for HTTP example for I-phone 3.0. i am doing SyncMl application , which is uses http based protocol to syncronise two databases (ie client and server ) Using POST and GET.So i will be sending data to server using POST and reading data using GET.If anybody has sample code or any hint what type framework would be used ??
I am going to assume you are interested in implementing some plain old HTTP client code. Requesting a web page etc.
I use NSURL to do my HTTP requests. It is pretty straightforward. You can read all about it on the NSURL Class Reference, but here is a snippet of sample code:
// set up your request
NSURL * url = [NSURL URLWithString:#"http://www.stackoverflow.com"];
NSURLRequest * request = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:60];
// create your connection with your request and a delegate (in this case
// the object making the request)
_connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
You just need to implement some delegate methods to handle the data responses
- (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSHTTPURLResponse*)response
- (void)connection:(NSURLConnection*)connection didReceiveData:(NSData*)data
- (void)connection:(NSURLConnection*)connection didFailWithError:(NSError*)error
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
ASIHTTPRequest is a great framework for HTTP Requests.
From the ASIHTTPRequest site:
ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications.

There is also a Google group. The code is hosted on github.
