我试图通过使用go-ethereum库的移动(android)与智能合约进行交互。Go-Ethereum:Android智能合约交互问题
的Android
final String address_string = "0x8607e627604495ae9812c22bb1c98bdcba581978";
String abi = "[{\"constant\":false,\"inputs\":[],\"name\":\"get_s\",\"outputs\":[{\"name\":\"\",\"type\":\"string\"}],\"payable\":false,\"type\":\"function\"},{\"constant\":false,\"inputs\":[{\"name\":\"new_s\",\"type\":\"string\"}],\"name\":\"set_s\",\"outputs\":[],\"payable\":false,\"type\":\"function\"},{\"inputs\":[{\"name\":\"d_s\",\"type\":\"string\"}],\"payable\":false,\"type\":\"constructor\"}]";
Address address = Geth.newAddressFromHex(address_string);
BoundContract contract = Geth.bindContract(address, abi, ec);
CallOpts callOpts = Geth.newCallOpts();
callOpts.setContext(ctx);
callOpts.setGasLimit(31500);
System.out.println("OUTPUT: " + getString(contract, callOpts));
//Setter String to Test Contract
Interfaces params = Geth.newInterfaces(1);
Interface anInterface = Geth.newInterface();
anInterface.setString(teststring);
params.set(0,anInterface);
return contract.transact(opts, "set_s", params);
//Getter String from Test Contract
Interfaces args = Geth.newInterfaces(0);
Interfaces results = Geth.newInterfaces(1);
Interface result = Geth.newInterface();
result.setDefaultString();
results.set(0, result);
contract.call(opts, results, "get_s", args);
String string = results.get(0).getString();
return string;
合同
pragma solidity ^0.4.9;
contract echo {
string s;
function echo(string d_s) {
s = d_s;
}
function set_s(string new_s) {
s = new_s;
}
function get_s() returns (string) {
return s;
}
}
预期的行为
与上Rinkeby blockchain部署智能合同成功的互动。
实际行为
对于设定部(合同): 'ABI:不能使用切片类型字符串作为参数'
对于吸气剂(合同): “ABI:不能解组串在为[]接口{}”
步骤来重现行为
1通过移动
2)连接到Rinkeby Testnet)创建通过移动
3.帐户)通过部署桌面智能合同
4)尽量W /通过移动智能交互合同
底线
如果有人已经能够通过中间人复仇的Android智能合同进行互动, 我希望得到一些assistanc即
