相关项目:

• boyachain
• regchainvm
• new_wasm_sdk

当前合约与链完整测试流程:

1.下载编译boyachain

2.启动boyachain(单独启动模式)

./boyachain clean
./boyachain init
./boyachain node bootstrap
./boyachain node --debug=true

具体命令以boyachain为主

3.下载wasm虚拟机regchainvm

4.在目录下启动wasm虚拟机

cargo run --bin web_service --features "web_service"

5.编译部署调用合约,以calculator为例

(0)调用blockchain start

Url: http://127.0.0.1:5678/vm/config/start

Methods : GET

Parameters :无 成功返回:

{
    "result": "success"
}

(1)编译合约

cd contract_test/calculator
./build.sh

(2)获取合约二进制文件

python3 readhex.py

(3)调用 部署合约接口

Url: http://127.0.0.1:5554/vm/exec_tx

Methods : GET

Parameters :(json格式)

{
"tx": {
    "hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "nonce": "0",
    "block_hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "block_number": "0",
    "transaction_index": "0",
    "from": "0x0000000000000000000000000000000000000000",
    "to": null,
    "value": "0",
    "gas": "0",
    "gas_price": "0",
    "input": "", // 合约中constructor函数参数
    "code": ""   // 合约16进制可通过http://10.0.0.20:3680/liusk/new_wasm_sdk/src/branch/master/readhex.py获取
    },
"blockheader": {
    "coinbase": "0x0000000000000000000000000000000000000000",
    "timestamp": 0,
    "number": "0",
    "difficulty": "0",
    "gas_limit": "0"
    }
}

客户端返回:

{
    "writeset": {
        "accounts": {
            "0x5943996084de04ffa21570dd6c1b91ea35af51ba": {
                "code": "0x..........", 
                "storage": {}
            }
        },
        "logs": []
    },
    "return_val": "0x"
}

(4)将writeset写入链中

Url: http://127.0.0.1:5678/vm/test/edit_account

Methods : GET

Parameters :(json格式)

{
        "accounts": {
            "0x5943996084de04ffa21570dd6c1b91ea35af51ba": {
                "code": "0x......",
                "storage": {}
            }
        },
        "logs": []
    }    

成功返回:

{
    "res": "success"
}

(5)调用 调用合约接口

Url: http://127.0.0.1:5554/vm/exec_tx

Methods : GET

Parameters :(json格式)

{
    "tx": {
        "hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
        "nonce": "0",
        "block_hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
        "block_number": "0",
        "transaction_index": "0",
        "from": "0x0000000000000000000000000000000000000000",
        "to": "0x5943996084de04ffa21570dd6c1b91ea35af51ba",
        "value": "0",
        "gas": "0",
        "gas_price": "0",
        "input": "", // 通过ethabi编码的函数名及参数
        "code": null
    },
    "blockheader": {
        "coinbase": "0x0000000000000000000000000000000000000000",

    "writeset": {
        "accounts": {},
        "logs": []
    },
    "return_val": "" //ethabi编码的函数调用返回
}
