WebSocket

Websocket API Reference

By default, Websocket API listens on 20335 port.

After a local node has been installed, Websocket can be started on the client end using the following command:

ontology --ws

The following option can be used to change the port at which the Websocket API listens:

ontology --wsport 1024

Interface definition

Ontology's client side Websocket interface has been standardized as follows:

sendrawtransaction

Send a raw transaction to be recorded on the chain.

The PreExec field in the request object is used to specify whether the contract needs to be pre-run. If the contract is to be pre-run, set the value to 1, else 0.

Sample request

{

    "Version": "1.0.0"
}

The result obtained is the transaction hash of the raw transaction.

getstorage

Fetches the value stored in a contract using the contract hash and the storage key.

The contract hash passed to the method can be generated in the following manner:

addr := types.AddressFromVmCode([]byte{0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

fmt.Println(addr.ToHexString())
