在包中找不到 React js 函数

Question

当使用来自 import { ElvWalletClient } from "@eluvio/elv-wallet-client";

的 ElvWalletClient.Item({"x":"1","y":"2"}) 时

我收到以下错误

eluvio_elv_wallet_client__WEBPACK_IMPORTED_MODULE_1_.ElvWalletClient.Item is not a function

在查看 source code 时，我确实看到了方法（第 338 行）

exports.Item = async function ({contractAddress, tokenId}) {
  Assert("Item", "Contract address", contractAddress);
  Assert("Item", "Token ID", tokenId);

  return await this.SendMessage({
    action: "item",
    params: {
      contractAddress,
      tokenId: tokenId.toString()
    }
  });
};

代码

import React, { useEffect, useState } from 'react'
import { ElvWalletClient } from "@eluvio/elv-wallet-client";

const Methods = ({client, userProfile}) => {
    const [itemData, setItemData] = useState(undefined);
    const popupClient = ElvWalletClient.Item({contractAddress: "0x48341be85e735322862d654a3f3c69854a16ccaf",itemId: "407"})
    .then(data => {
        itemData(data)

      })
      .catch(error => console.error(error));

    return (
        <div>
            <div>{itemData}</div>
        </div>
    )
}

export default Methods

初始化钱包

ElvWalletClient.InitializeFrame({
      walletAppUrl: "https://wallet.contentfabric.io",
      target: element,
      requestor: "WWE Moonsault",
      loginOnly: true,
      darkMode: true,
      // NOTE: This should be changed to tenant slug + marketplace slug when the marketplace is published
      marketplaceId: "iq__2zMYXQ6SwRFhjAc73ppcn4RP5KX3"
    })
      .then(client => {
        SetClient(client)

        // If previously used client is present, ensure it is destroyed
        if(previousClient) {
          previousClient.Destroy();
        }
      })
      .catch(error => console.error(error));

在尝试调用该函数之前，您是否初始化了钱包？从您包含的代码来看，似乎并非如此。

根据此包的 source 代码，您不应使用默认构造函数，而应使用以下之一：

InitializeFrame: 在新的 iframe 中初始化媒体钱包
InitializePopup: 在新的 window

尝试以下方法之一：

import { ElvWalletClient } from "@eluvio/elv-wallet-client";

// Initialize in iframe at target element
const walletClient = await ElvWalletClient.InitializeFrame({
  requestor: "My App",
  walletAppUrl: "https://wallet.contentfabric.io",
  target: document.getElementById("#wallet-target")
});
    
// Or initialize in a popup
const walletClient = await ElvWalletClient.InitializePopup({
  requestor: "My App",
  walletAppUrl: "https://wallet.contentfabric.io",
});

如果您已经初始化了钱包并且它是您作为道具传递给 Method 的值，请尝试在 client 上调用 Item():

const Methods = ({client, userProfile}) => {
    const [itemData, setItemData] = useState(undefined)

    // Change this to const popupClient = client.Item({...})
    const popupClient = ElvWalletClient.Item({contractAddress: "0x48341be85e735322862d654a3f3c69854a16ccaf",itemId: "407"})
    
    ...
}

作为旁注，由于 InitializeFrame 和 InitializePopup 方法是 async，在尝试调用其他方法之前检查 promise 是否已解决可能是有益的client.
