Getting started

Setting up the development environment

There are a few technical requirements before we start. Please install the following:

• Python 3.7
• Git

Introduction

In order to call the method in the contract, we need to fill in the default-config.json file. The following describes the meaning of each parameter in default-config.json in detail.

{
    "defaultWallet": "wallet.json",
    "password": {
        "AUr5QUfeBADq6BMY6Tp5yuMsUNGpsD7nLZ": "password",
        "AecaeSEBkt5GcBCxwz1F41TvdjX3dnKBkJ": "password",
        "AQvZMDecMoCi2y4V6QKdJBtHW1eV7Vbaof": "password"
    },
    "deployConfig": {
        "name": "contract name ",
        "version": "contract version",
        "author": "the author of contract",
        "email": "email address",
        "desc": "a description for your contract",
        "needStorage": true,
        "payer": "AUr5QUfeBADq6BMY6Tp5yuMsUNGpsD7nLZ",
        "gasPrice": 0,
        "gasLimit": 31000000
    },
    "invokeConfig": {
        "abi": "hello_ontology_abi.json",
        "sleepTime":0,
        "defaultPayer": "AUr5QUfeBADq6BMY6Tp5yuMsUNGpsD7nLZ",
        "gasPrice": 0,
        "gasLimit": 20000,
        "functions": [            
        ]
    }
}

defaultWallet: Wallet file name under the wallet folder.

password: Used to configure the password corresponding to the address in the wallet corpus.

deployConfig: Basic contract information, used when contract deployment.

invokeConfig: Parameters needed to configure for invoking function in contract.

• abi Used to configure the abi file directory, the default is contracts/build/.
• sleepTime Used to specify the time required to perform a non-pre-execution method.
• defaultPayer Used to specify the payer for transaction fee.
• gasPrice Used to set the value of gasPrice.
• gasLimit Used to set the value of gasLimit.
• functions Parameters needed to configure functions in the contract.

Function detailed configuration:

{
    "operation": "testByteArrayListAndStr",
    "args": [
        {
            "name": "bytearrayList",
            "value": [
                "ByteArray:Hello",
                "ByteArray:world"
            ]
        },
        {
            "name": "msgStr",
            "value": "String:hello"
        },
        {
            "name": "msgInt",
            "value": 10
        },
        {
            "name": "msgBool",
            "value": true
        }
    ],
    "signature": {
        "m":1,
        "signers":[
            "AUr5QUfeBADq6BMY6Tp5yuMsUNGpsD7nLZ"
        ]
    },
    "preExec": true
}

• operation Used to set function name.
• args Used to set parameter required by function.
  • name: parameter name.
  • value: parameter value. In this example, the first parameter value is array and it should be configurated like this example.Elements in the array support basic data types, if the data type of element is int or boolean, you don't need to declare the parameter type, if the data type of element is String or byte[], you need to explicitly declare the data type and the declaration format is "data type: data value".
• signature Used to set signer.
  • m indicates the minimum number of signatures required in the multi-signature. m=1 indicate Single sign, m > 2 indicates multi-signature.
  • signers indicates all the addresses of signers.
• preExec Used to set the execution mode of the function, true indicates this transaction will not update state of blockchain, false indicates this transaction will update state of blockchain and this operation need pay transaction fee.
