I tried to deploy my contract on Ropsten TestNet with infura and web3.js, however when I used some functions it returned 405 error. I notice that maybe I could not use web3.eth.getTransaction() when infura, however when I use following script

    <script src="./node_modules/web3/dist/web3.min.js"></script>

this function is called several times.

How can Iavoid the error, do I need to modity web3.min.js? Or is there any way to replace infura?
