Access Request Data sent, inside requestFailed Function ASIHttpRequest - objective-c

Question

How to access the (POST)data sent with the request from the requestFailed/requestFinished function.
- (void) abc {
NSString *postString = #"john";
NSURL *url = [NSURL URLWithString:#"http://abc.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setPostValue:postString forKey:#"name"];
[request setDelegate:self];
[request startAsynchronus];
}
- (void) requestFinished:(ASIHTTPRequest *)request
{
// Question is whether the request holds the sent post values.
// If it holds. how can we access them.
// i tried using [request valueForKey:#"name"];
// but it won't work.
}

Answer 1

Handling success and failure for multiple requests in delegate methods
If you need to handle success and failure on many different types of
request, you have several options:
If your requests are all of the same broad type, but you want to
distinguish between them, you can set the userInfo NSDictionary
property of each request with your own custom data that you can read
in your finished / failed delegate methods. For simpler cases, you can
set the request’s tag property instead. Both of these properties are
for your own use, and are not sent to the server.
If you need to handle success and failure in a completely different way for each
request, set a different setDidFinishSelector / setDidFailSelector for
each request For more complex situations, or where you want to parse
the response in the background, create a minimal subclass of
ASIHTTPRequest for each type of request, and override requestFinished:
and failWithError:.
That provided me a good solution to handle different requests.

Answer 2

You could try this -
- (void)requestFinished:(ASIHTTPRequest *)request {
NSLog(#"Response %d ==> %#", request.responseStatusCode, [request responseString]);
}
You can also handle other methods if you choose, such as:
- (void)requestStarted:(ASIHTTPRequest *)request;
- (void)requestFailed:(ASIHTTPRequest *)request;
The docs are located at http://allseeing-i.com/ASIHTTPRequest/ and are fantastic.

Answer 3

You can cast your request into a ASIFormDataRequest:
if ([request isKindOfClass:[ASIFormDataRequest class]]) {
ASIFormDataRequest *requestWithPostDatas = (ASIFormDataRequest *)request;
NSArray *myPostData = [requestWithPostDatas getPostData];
}
You will also have to make "postData" accessible with a "getPostData" public function in ASIFormDataRequest.
