Web3.providers with httpProvider

[hatshu]

I have see all provable-things/ethereum-examples/solidity/truffle-examples/ are in the js this variable
const web3 = new Web3(new Web3.providers.WebsocketProvider('ws://localhost:9545'))

Can we have any example with Web3.providers.HttpProvider('http://localhost:9545'))
I cant use in my node websocket and i need to use oraclizeAPI.sol.

Thx a lot¡¡¡¡
