If it’s really a RESTful API, then you use GET to retrieve the contents of a resource, and POST to create a new resource (without specifying a URL for it.) In general, anything that has side effects (i.e. changing the state of the data on the server) cannot be a GET request. And PUT requests only create new resources (at the given URL), and DELETE only deletes resources. So anything that doesn’t fall into those categories is going to be a POST. > If I use "GET" as http method and if the server web service is being > implemented in "POST" then I get 404 or similar http error code. > Is there any way to find out the http method type being implemented for a web > server API? Read the documentation of the service, or ask an expert for help. Seriously. HTTP is not self-documenting this way. The answer about looking at the 405 response is correct as far as it goes, and there’s also the OPTIONS method, but both of those will only tell you what methods are allowed on that URL, not what they *mean*. If you try to implement a client for a web API by guesswork, your code is likely to be fragile and break in the future if any changes are made on the server side. Unless you’re trying to reverse-engineer a proprietary API, you should really really follow the documentation. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
