Setting non-default HTTP headers with AFHTTPClient

Question

I see how to set default headers using AFHTTPClient, but I would like to set certain headers only when I perform requests to certain resources. Is there a way to this than building my own NSURLRequest (with the correct headers), creating an operation and enqueuing that operation to my subclass of AFHTTPClient?

Answer 1

If your network request are going to differ significantly it might be easier to create multiple AFHTTPClient subclasses to deal with the different cases. Adding your headers in in - (id)initWithBaseURL:(NSURL *)url.

Otherwise whenever you are creating your NSURLRequest with your AFHTTPClient subclass you are able to set headers with a few different methods:

[client setDefaultHeader:@"key" value:@"value"];
[client setAuthorizationHeaderWithUsername:@"username" password:@"password"];
[client setAuthorizationHeaderWithToken:@"token"];

You can set these before creating your NSURLRequest with something like:

NSURLRequest *request = [client requestWithMethod:@"someMethod" path:@"somePath" parameters:someParameters];

Then your headers should only be in that request. You can also clear your authorization header using - (void)clearAuthorizationHeader. Taking a bit from the AFNetworking source code you can remove any necessary objects from the NSMutableDictionary if they are not otherwise removed.
