ganache跟 hardhat 一样,是运行在本地的ethereum网络。不一样的是,ganache 带有友好的操作界面。具备explorer,这个太给力了。

注意事项

1. 务必安装好一个nodejs , 例如16.x  这样ganache才可以查看truffle项目中的contract

2. 关掉防火墙(如果你是在虚拟机,wsl 或者docker中使用的话) 否则无法访问ganache rpc server

3. 特别特别注意:关掉Linux 下的代理(例如http_proxy, https_proxy )  否则无法访问ganache rpc server

windows下的安装方式

1. 到官网,下载exe, 安装

2. 运行后,编辑它。

3. 填写个名字

4. 看一下其他配置

5. 其他选项: 记录日志,选择日志文件夹等

6. 主界面的说明

使用之前:

使用curl 命令确认是否可以访问:

curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getBalance","params": ["0xDEC781c67a86570c004c7840BE1AddAF51C39487", "latest"],"id":1}' http://192.168.10.54:3355 -vvv

Note: Unnecessary use of -X or --request, POST is already inferred.
*   Trying 192.168.10.54:3355...
* TCP_NODELAY set
* Connected to 192.168.10.54 (192.168.10.54) port 3355 (#0)
> POST / HTTP/1.1
> Host: 192.168.10.54:3355
> User-Agent: curl/7.68.0
> Accept: */*
> Content-Type: application/json
> Content-Length: 117
>
* upload completely sent off: 117 out of 117 bytes
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK
< Content-Type: application/json
< Date: Tue, 21 Jun 2022 00:22:24 GMT

<
* Connection #0 to host 192.168.10.54 left intact
{"id":1,"jsonrpc":"2.0","result":"0x56266a7b7dbf06000"}

如果是上面这样,就没问题。

使用 浏览器打开 该地址: 如果能看到 400 Bad Request, 就说明 该server已经在运行了

7. 在truffle中使用:  修改truffle-config.js 增加对应的network:

require('dotenv').config();
const HDWalletProvider = require('@truffle/hdwallet-provider');

module.exports = {
  networks: {
// 这个就是需要我们增加的 ganache: { provider: () => new HDWalletProvider("gym host tag slow tent leopard woman emerge pear ??? ??? ???", "http://192.168.10.54:3355"), network_id: "5777", networkCheckTimeout: 30000, timeoutBlocks: 200, addressIndex: 2 }, }, compilers: { solc: { // version: "^0.8.0", version: "0.8.15", } }, plugins: ['truffle-plugin-verify'], api_keys: { etherscan: '4ANBPF8KQQHJ6J9BBU7WU53BNPDMXHYJMW' } };

8. 运行前,确保你没有使用 http_proxy , 例如 

9. 部署:truffle deploy --network ganache --verbose-rpc --interactive --reset

可以说是非常的爽歪歪了。在本地运行速度奇快,瞬间结束(goerli等网络需要一个30秒左右)

10. 查看Ganache Dashboard

可以看出,上面出现的3个Contract Creation tx, 都依次出现在了这里(时间倒叙排序)

(创建的时间顺序: 从上到下)

MyTestNft      0x4ca4fe4f388e9b124554975c0bae0e02a1ad9f49181356b8c66dbb2ee9dbbe9d

MyTestNftB    0xef23e81d51c704699b3eb73cd846db363efbcdcbc57a41b6527429221fbc7ff8

MyTestNftC    0xf5d1849fd5356881f33b4ce696e318d47a87a8204a657bc3c1009ceafc19caa2

在Ganache 中的Transactions :越在上面的,就是越新的 tx

点击可以查看详情:

可以看到目前还没有event

点击对应的account, 发现balance在变少

每个tx对应一个block

可以看到都已经部署了

点击 Contract的详情,就可以看到下面的页面:

点击查看log:

最常见的问题

1. code -32603  , socket hang up

truffle deploy --network ganache

Compiling your contracts...
===========================
> Everything is up to date, there is nothing to compile.

/mnt/d/workspace/test_erc_721_in_truffle/node_modules/eth-block-tracker/src/polling.js:51
        const newErr = new Error(`PollingBlockTracker - encountered an error while attempting to update latest block:\n${err.stack}`)
                       ^

  }
} {
  code: -32603,
  message: 'socket hang up',
  data: { originalError: { code: 'ECONNRESET' } }
}

跟ganache 没有连通。 解决办法:

1. 重启ganache 

2. 重启terminal 不要使用代理   (这里最关键, 我被这里卡了大半个下午+2小时上午+一晚上琢磨这个事儿)

3. 关闭防火墙  

4. 检查truffle-config.js 中的network是否正确

2. connect ECONNREFUSED 0.0.0.0:7545

在js 中,凡是带有 EXX 开头的,都是 Error, 
这里表示 0.0.0.0  7545 的rpc server无法连接。
检查一下该node是否运行,或者该node 的配置是否是你要的
