How to exec ink contract method ?

[mohaijiang]

Can I exec ink contract function with go-substrate-rpc-client ?

The following picture is an example of js, does go have a similar method?

// Construct the API as per the API sections
// (as in all examples, this connects to a local chain)
const api = await ApiPromise.create();

// Construct our Code helper. The abi is an Abi object, an unparsed JSON string
// or the raw JSON data (after doing a JSON.parse). The wasm is either a hex
// string (0x prefixed), an Uint8Array or a Node.js Buffer object

const json =　JSON.parse(fs.readFileSync('src/contract/flipper.contract','utf8'));

const contractAbi = new Abi(json,api.registry.getChainProperties())



const keyring = new Keyring({ type: 'sr25519',ss58Format: 42 });
const pair = keyring.addFromUri('//Alice');

const contract = new ContractPromise(api, contractAbi, "some-address");
const value = 0;
const incValue = 1;
await contract.tx
    .flip({ value, gasLimit },) // 方法名({value,gasLimit}, ...params )  此处flip 是合约方法名
    .signAndSend(pair, (result) => {
        if (result.status.isInBlock) {
            console.log('in a block');
        } else if (result.status.isFinalized) {
            console.log('finalized');
        }
    });

We have not tested this nor any EVM-related calls so far. Is there a specific chain that we can use for checking this? We need to take a look at the pallet and see the arguments for the extrinsic that you're trying to call.
