I tried to call this function through the React app:

我试图通过Reaction应用程序调用此函数：


function getData(address _userAddress, string [] memory _attribute) public payable returns ( string[] memory, Person[] memory){
Some logic . . .

}

It includes emit and its return array, I always can't see logs from ether scan https://sepolia.etherscan.io/ and from Metamask, the transaction label was Send :
enter image description here

它包括发射和它的返回数组，我总是看不到来自以太扫描https://sepolia.etherscan.io/的日志和来自MetamASK的交易标签被发送：在这里输入图像描述


but if I call this function by Remix Platform I can see logs :

但是如果我通过Remix Platform调用这个函数，我可以看到日志：


enter image description here

在此处输入图像描述


In Metamask, the transaction label was Contract Interaction:

在Metamask中，交易标签是合同交互：


enter image description here

在此处输入图像描述


This is the way how to interact with my smart contract from the fronted :

以下是如何从正面与我的智能合同进行交互的方式：


const result = await  contract.methods.getDataWithSharing(userAddress,selectedAttributes).send({
            from: defaultAccount,
            value:3
        });

In my contract, I have many functions that I can interact with through fronted except the above function (payable type).

在我的合同中，我有许多功能，我可以通过前端交互，除了上面的功能(支付型)。


Dose any one can help me to resolve this issue?

有谁能帮我解决这个问题吗？


Regards,

向您致敬，

Not sure I follow. What is the exact issue here? If you are looking for logs, you wont get that from contract.methods.getDataWithSharing response.

我不确定我听懂了。这里的确切问题是什么？如果您正在寻找日志，那么您将无法从以下响应中获得该结果。

@RobinThomas Hi Robin, Yes I want see logs for getDataWithSharing method, but I can't see it after I call it from frontend app, but if I call it through Remix I can see logs on ether scan.

@RobinThomas Hi Robin，是的，我想看到getDataWithSharing方法的日志，但在前端APP调用后看不到，但如果我通过Remix调用，我可以在以太扫描上看到日志。

Hi @RobinThomas, I will try it and tell you what happen. Thanks.

嗨@罗宾·托马斯，我会试一试，然后告诉你发生了什么。谢谢。

To retrieve the logs of a transaction, you need to retrieve the transaction receipt.

要检索事务的日志，您需要检索事务收据。


You can do that by:

您可以通过以下方式做到这一点：


const tx = await contract.methods.getDataWithSharing(attributes).send({
    from: defaultAccount,
    value: 3
});

const txReceipt = await tx.wait();

console.log(txReceipt.logs);

The logs are not available when you make a transaction. You have to wait for the transaction to be mined onto a block (which is what tx.wait does).

当您进行交易时，日志不可用。您必须等待事务被挖掘到块上(这就是tx.Wait所做的)。


The logs will be available once you get the transaction receipt.

一旦您收到交易收据，日志就可以使用了。
