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.
It is suitable performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The included ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.
It provides:
- A straightforward interface for submitting data to and fetching data from webservers
- Download data to memory or directly to a file on disk
- The ability to submit files on local drives as part of POST data, compatible with the HTML file input mechanism
- Easy access to request and response HTTP headers
- Progress delegates (NSProgressIndicators and UIProgressViews) to show information about download AND upload progress
- Auto-magic management of upload and download progress indicators for operation queues
- Basic + Digest authentication support, credentials are automatically re-used for the duration of a session, and can be stored for later in the Keychain.
- Cookie support
- GZIP support for response data
- Based on NSOperation to make queuing requests and background operation easy
- Comes with a broad range of unit tests
