7. sendrawtransaction

send transaction.

Parameter instruction

Hex: Serialized signed transactions constructed in the program into hexadecimal strings. Building the parameter,please refer to NewNativeInvokeTransaction in ontology-go-sdk/rpc.go

PreExec : set 1 if want prepare exec smartcontract

How to build the parameter?

    // get sdk instance
    sdk := goSdk.NewOntologySdk()
    rpcClient := sdk.Rpc
    // generate invoke native contract transaction; if you want to invoke neo vm contrace,
    // use NewNeoVMSInvokeTransaction
    // cversion is contract version, method is contract method name, params is []interface{}type,
    // represent the contract method param
    // For example: 
    // NewNativeInvokeTransaction(0, 200000, byte(0),utils.ParamContractAddress,
    //      "getGlobalParam", []interface{}{global_params.ParamNameList{"gasPrice"}})
    tx, err := rpcClient.NewNativeInvokeTransaction(gasPrice, gasLimit, cversion, contractAddress, method, params)
    if err != nil {
    	return common.UINT256_EMPTY, err
    }
    // sign for tx, signer is sender of transaction
    err = rpcClient.SignToTransaction(tx, signer)
    if err != nil {
        return common.UINT256_EMPTY, err
    }

    txbf := new(bytes.Buffer)
    err = tx.Serialize(txbf);
