尝试使用 web3j 调用合约中的某些函数。我遵循了 Solidity 指南并获得了这份合同的 .abi 和 .bin - https://etherscan.io/address/0x9dda40dabd849bbb087dcbcf0c5223ec5ffa0ad7#code。然后使用 web3j 命令行制作 .java 文件包装器,输出到正确的目录。
一切正常,但以下几行:
public static final Event FUNDSWITHDRAWN_EVENT = new Event("FundsWithdrawn",
Arrays.<TypeReference<?>>asList(new TypeReference<Address>() {}, new TypeReference<Uint256>() {}));
;
public static final Event FUNDSDEPOSITED_EVENT = new Event("FundsDeposited",
Arrays.<TypeReference<?>>asList(new TypeReference<Address>() {}, new TypeReference<Uint256>() {}));
;
public static final Event SERVERADDED_EVENT = new Event("ServerAdded",
Arrays.<TypeReference<?>>asList(new TypeReference<Uint256>() {}));
;
public static final Event SERVERREMOVED_EVENT = new Event("ServerRemoved",
Arrays.<TypeReference<?>>asList(new TypeReference<Uint256>() {}));
;
public static final Event GAMESTARTED_EVENT = new Event("GameStarted",
Arrays.<TypeReference<?>>asList(new TypeReference<Uint256>() {}, new TypeReference<DynamicArray<Address>>() {}));
;
public static final Event GAMEENDED_EVENT = new Event("GameEnded",
Arrays.<TypeReference<?>>asList(new TypeReference<Uint256>() {}, new TypeReference<Address>() {}, new TypeReference<Address>() {}, new TypeReference<Address>() {}));
;
抛出错误:
Event() in Event cannot be applied to:
Expected Parameters:
Actual Arguments:
name:
String
"ServerAdded"
indexedParameters:
List<TypeReference<?>>
Arrays...new TypeReference<Uint256>() {})
nonIndexedParameters:
List<TypeReference<?>>
而这两行:
public static final Event OWNERSHIPRENOUNCED_EVENT = new Event("OwnershipRenounced",
Arrays.<TypeReference<?>>asList(new TypeReference<Address>(true) {}));
;
public static final Event OWNERSHIPTRANSFERRED_EVENT = new Event("OwnershipTransferred",
Arrays.<TypeReference<?>>asList(new TypeReference<Address>(true) {}, new TypeReference<Address>(true) {}));
;
给出错误:TypeReference 中的 TypeReference() 不能应用于 (boolean)
我不是合约的创建者,但它在 web3js 和 metamask 实现中确实可以正常工作。我在想一件事,因为这些事件是针对服务器端的,我什至需要包括它们吗?(尽管您可以看到它们稍后会被引用)但我只是想知道 .bin 文件的使用是否会迫使您不进行更改?无论如何,这是新的,所以任何帮助或指示表示赞赏,谢谢。
