使用 Azure 乙太坊聯盟部署智能合約不起作用

  • March 9, 2017

我創建了一個 Azure 乙太坊聯盟。部署的乙太坊網路在負載均衡器後面有 2 個事務節點。通過 Putty，我連接到其中一個交易節點。

然後我進入

geth attach

現在控制台已打開。安裝了solidity編譯器。然後我解鎖要使用的帳戶：

personal.unlockAccount(eth.accounts[1], "{your password}");

賬戶餘額為：

400000000000000000000

然後我編譯程式碼：

var greeterSource = 'pragma solidity ^0.4.9; /** @title Mortal.*/ contract mortal { /* Define variable owner of the type address*/ address owner; /**@dev this function is executed at initialization and sets the owner of the contract. */ function mortal() { owner = msg.sender; } /**@dev Function to recover the funds on the contract. */ function kill() { if (msg.sender == owner) { selfdestruct(owner); } } } /** @title Greeter.*/ contract greeter is mortal { /* define variable greeting of the type string */ string greeting; /**@dev This function runs when the contract is executed. * @param _greeting Greeting message. */ function greeter(string _greeting) public { greeting = _greeting; } /* main function */ /**@dev This function returns the greeting message. * @return greeting The greeting message. */ function greet() constant returns (string) { return greeting; } }';

var greeterCompiled = web3.eth.compile.solidity(greeterSource);

結果：

{
 <stdin>:greeter: {
   code: "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",

Address: " + contract.address); console.log(contract); } } })

結果是：

   {
 abi: [{
     constant: false,
     inputs: [],
     name: "kill",
     outputs: [],
     payable: false,
     type: "function"
 }, {
     constant: true,
     inputs: [],
     name: "greet",
     outputs: [{...}],
     payable: false,
     type: "function"
 }, {
     inputs: [{...}],
     payable: false,
     type: "constructor"
 }],
 address: undefined,
 transactionHash: null
}

如您所見，應該包含足夠的氣體。但隨後什麼也沒有發生，也不會分配任何地址。賬戶餘額也保持不變。我沒有正確連接（當我執行 admin.peers 時，我看到所有其他連接的節點）或者可能是什麼問題？

現在有一個解決方案（感謝幫助我解決這個問題的同事 :) 但這有點令人不滿意，因為我不知道為什麼它現在有效而不是以前有效。

我的同事使用了不同的氣體值（1000000 而不是 45000000000）並且不得不web3從var greeter = greeterContract.new(_greeting,{from:web3.eth.accounts[1], ...

我只需要更改氣體值，但可以使用web3…

所以現在對我有用的程式碼如下所示：

var greeter = greeterContract.new(_greeting,{from:web3.eth.accounts[1], data: greeterCompiled["<stdin>:greeter"].code, gas: 1000000}, function(e, contract){
   if(!e) {
       if(!contract.address) {
           console.log("Contract transaction send: TransactionHash: " + contract.transactionHash + " waiting to be mined...");
       } else {
           console.log("Contract mined! Address: " + contract.address);
           console.log(contract);
       }
   }
})

和我的同事

var greeter = greeterContract.new(_greeting,{from:eth.accounts[1], data: greeterCompiled["<stdin>:greeter"].code, gas: 1000000}, function(e, contract){
   if(!e) {
       if(!contract.address) {
           console.log("Contract transaction send: TransactionHash: " + contract.transactionHash + " waiting to be mined...");
       } else {
           console.log("Contract mined! Address: " + contract.address);
           console.log(contract);
       }
   }
})
