[英]Account balance zero when trying to make an transaction on private network
EDIT: solved, was caused by declaring this.web3 instead of web3 编辑:解决,是由声明this.web3而不是web3引起的
I'm running a private network with truffle and I'm facing this weird problem where at Metamask and Mist show that I have balance of 100 eth. 我正在运行带有松露的专用网络,并且遇到了这个奇怪的问题,在Metamask和Mist处显示我的平衡为100 eth。 When I try actually to make an transaction it says that the account has ZERO eth. 当我实际尝试进行交易时,它说该帐户具有零eth。 I have a contract that is fairly complex and I'm not sure what is the problem. 我的合同相当复杂,我不确定是什么问题。
I have tried restarting truffle and recompiling and remigrating the contracts a few times and I have reinstalled metamask multiple times. 我尝试几次重新启动松露,重新编译和迁移合同,并且多次重新安装了metamask。 When I tried Mist, it also does this. 当我尝试Mist时,它也会这样做。
I'm fairly new at smart contracts, but I'm trying to create a somewhat big application with it. 我在智能合约方面还很陌生,但是我正在尝试用它创建一个更大的应用程序。 I code the contracts with Solidity and I have tested the contracts on remix without problems and I can manipulate the contracts via truffle just fine. 我使用Solidity对合同进行编码,并且已经对混音中的合同进行了测试,没有任何问题,并且可以通过松露操作合同。 I think it may be because of the front.. I'm programming it with react. 我认为可能是因为前端。我正在用react编程。 This is the specific part of code in js that I call the function. 这是我称为js的代码中的特定部分。 It's just a plain auth mechanism. 这只是一种简单的身份验证机制。 I use truffle-contract and this.database is a Contract. 我使用松露合约,this.database是合约。
authAddress(sotu, password) {
return new Promise ((resolve, reject) => {
this.database.deployed().then(instance => {
return instance.authAddress(sotu, password);
}).then(res => {
resolve();
}).catch(error => {
reject(error);
});
});
}
The solidity counterpart is follows: 坚固性对应如下:
function authAddress(string sotu, string password) public {
//Check if already logged in
require(authenticatedAddresses[msg.sender] == address(0));
Person p = persons[keccak256(sotu)];
p.login(keccak256(password), msg.sender);
authenticatedAddresses[msg.sender] = p;
}
I'm still learning these things, but I'm a bit bummed that this problem exists and nobody else seems to have countered this as far as I have tried to search. 我仍在学习这些内容,但是对于这个问题的存在我感到有些沮丧,就我尝试搜索的情况而言,似乎没有其他人对此提出反驳。 Have I missed something completely? 我完全错过了什么吗?
EDIT: 编辑:
Here's tbe web3 provider init: 这是web3提供程序init:
try {
if(web3 != null) {
this.web3 = new Web3(web3.currentProvider);
}
} catch (error) {
this.web3 = null;
}
I try to make the site only available if you have metamask or such alike. 我尝试仅当您具有metamask或类似标记时才使该站点可用。 I'd like to to wrap the web3 to a class, but if that screws things uo let me know. 我想将web3包装到一个类中,但是如果这使uo搞砸了,请告诉我。
My databasehandler init 我的数据库处理程序初始化
initDatabaseHandler() {
return new Promise((resolve, reject) => {
this.databaseHandler = new DatabaseHandler();
this.databaseHandler.loadContract(this.state.coinbase, this.web3.currentProvider)
.then(() => {
this.databaseHandler.getAccountInfo()
.then(info => {
this.setState({userinfo: info}, resolve());
}).catch(err => {
console.log(err);
});
})
.catch(err => reject(err));
});
}
And the abstracted contract loader: 和抽象的合同加载器:
loadContract(coinbase, provider) {
return new Promise((resolve, reject) => {
this.database = new Contract(Database);
this.database.setProvider(provider);
this.database.web3.eth.defaultAccount = coinbase;
this.person = new Contract(Person);
this.person.setProvider(provider);
this.person.web3.eth.defaultAccount = coinbase;
console.log(this.database.web3.eth.defaultAccount);
resolve();
});
}
解决,是由于声明了this.web3而不是web3
