我发现了一个错误:
ValueError:{'code':-32601,'message':'方法eth_sendTransaction不存在/不可用'}
当我在infura.io(ropsten测试网络)中部署Solidity智能合约时。但是,当我尝试使用ganache时,该合同已在ganache testRPC上成功部署。 这是我的Python文件下面的代码。
from web3 import Web3
from solcx import compile_files, link_code
import json
w3 = Web3(Web3.HTTPProvider("https://ropsten.infura.io/v3/<PROJECT_ID>"))
def separate_main_n_link(file_path, contracts):
# separate out main file and link files
# assuming first file is main file.
main = {}
link = {}
all_keys = list(contracts.keys())
for key in all_keys:
if file_path[0] in key:
main = contracts[key]
else:
link[key] = contracts[key]
return main, link
def deploy_contract(contract_interface):
# Instantiate and deploy contract
contract = w3.eth.contract(
abi=contract_interface['abi'], bytecode=contract_interface['bin'])
acct = w3.eth.account.privateKeyToAccount("<PRIVATE_KEY>")
# Get transaction hash from deployed contract
tx_hash = contract.deploy(transaction={'from': acct.address})
# Get tx receipt to get contract address
tx_receipt = w3.eth.getTransactionReceipt(tx_hash)
return tx_receipt['contractAddress']
def deploy_n_transact(file_path, mappings=[]):
# compile all files
contracts = compile_files(file_path, import_remappings=mappings)
link_add = {}
contract_interface, links = separate_main_n_link(file_path, contracts)
# print (contract_interface)
# first deploy all link libraries
# here link is refers to the second contarct "stringUtils.sol"
for link in links:
link_add[link] = deploy_contract(links[link])
# now link dependent library code to main contract binary
# https://solidity.readthedocs.io/en/v0.4.24/using-the-compiler.html?highlight=library
if link_add:
contract_interface['bin'] = link_code(contract_interface['bin'], link_add)
# return contract receipt and abi(application binary interface)
return deploy_contract(contract_interface), contract_interface['abi']
contract_address, abi = deploy_n_transact(['./contracts/Adoption.sol'])
with open('Adoption.json', 'w') as outfile:
data = {
"abi": abi,
"contract_address": contract_address
}
json.dump(data, outfile, indent=4, sort_keys=True)
并且Solidity文件的版本为0.5.0。
pragma solidity ^0.5.0;
contract Adoption {
address[16] public adopters;
// Retrieving the adopters
function getAdopters() public view returns (address[16] memory) {
return adopters;
}
// Adopting a pet
function adopt(uint petId) public returns (uint) {
require(petId >= 0 && petId <= 15);
adopters[petId] = msg.sender;
return petId;
}
}
但是我认为这不会影响在区块链测试网络上部署固态智能合约的过程。 预先感谢。
