具有字符串参数的事件不起作用(未编入索引)

Question

我正在尝试听一个在本地运行的rinkeby测试事件。当我的参数是int时，比如event EventTester(int values);，当我将事件参数更改为string (它没有被索引)时，每件事情都正常工作，它不工作，我也看不到日志。event EventTester(string values);。知道为什么吗？在https://rinkeby.etherscan.io上检查事务时，我没有看到Events选项卡。

谢谢

我只是在罗普斯滕身上试了一试，看起来很管用。下面是事务：https://gist.github.com/pabloruiz55/d73fabb23677f146c58d8c4d3950c0fa

你可以在日志上看到我发送了一个字符串"hola“。

我使用的代码与您编写的代码完全相同，并在Remix上进行了测试。

(无法在Rinkeby上测试它，因为我刚刚用完了以太，但如果您给我寄来一些，我很乐意尝试一下:0x0fC20E774EA6674087494a36F8F8F8f09a4Ee3a131)

更新:在Rinkeby上工作也很好。https://rinkeby.etherscan.io/tx/0x5cf1cfd9c401b9b2d2c0d7a7d967f50e33aaa9bf9cfc97afad9f90b247a93ee9#eventlog

这是Remix的屏幕截图，以防万一。

如果这不是使用web3的约束，我建议您使用它来调用该方法，这将避免大量常见错误(已在包装器中解决)。

与web3@^0.20.6：

contractInstance.getOut.sendTransaction('hi', (err, result) => {
  if (err) {
    console.error(err);
  }

  console.log(result);
});

与web3@^1.0.0

contractInstance.methods.getOut('hi').send({ from: address }).then((result) => {
  console.log(result);
})
.catch((err) => {
  console.error(err);
});
