我正在尝试使用go-ethereum库通过移动设备(android)与智能合约进行交互。
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;
}
}
预期行为
与Rinkeby区块链上已部署的智能合约成功互动。
实际行为
对于setter(合约): 'abi:不能将slice用作类型字符串作为参数'
对于getter(合约): 'abi:无法将字符串解组到[] interface {}'
重现行为的步骤
1。)通过手机
连接到Rinkeby Testnet2。)通过手机创建帐户
3.。)通过桌面部署智能合约
4.尝试通过移动设备与智能合约进行互动
底线
如果有人能通过go-ethereum android与智能合约互动, 我将不胜感激。
