There will be no IO function like `http_get_content` because we can't securely rely on them. Instead the method will be to rely on a trusted entity (or a group of trusted entities) to sign an ethereum transaction containing some data that will be used by the contract. For instance you could take a look at Reality Keys, a "trusted data feeds" platform [1]. If you want to reduce the need to trust a single party you can also use a SchellingCoin system, described as a "decentralized data feed" in the ethereum white paper v2 [2].
