Express.js POST 处理程序中的异步/等待

Question

我正在尝试在 POST 处理程序中调用异步 function。

我试图调用的 function 如下（此代码有效）：

const seaport = require("./seaport.js");

// This function creates a fixed price sell order (FPSO)
async function createFPSO(ownerAddress, contractAddress, tokenId, startAmount, expirationTime = 0) {
  const fixedPriceSellOrder = await seaport.createSellOrder({
    asset: {
      tokenId: tokenId,
      tokenAddress: contractAddress,
    },
    startAmount: startAmount,
    expirationTime: expirationTime,
    accountAddress: ownerAddress,
  });
  console.log(`Successfully created a fixed-price sell order! ${fixedPriceSellOrder.asset.openseaLink}\n`);
}

createFPSO(MY_ADDRESS, NFT_CONTRACT_ADDRESS, "2", 0.01);

由于上面的代码有效，我现在尝试将其传输到 POST 处理程序，如下所示：

const express = require('express');
const app = express();
app.use(express.json());
const seaport = require("./seaport.js");

app.post('/create/fixedprice', async (req, res, next)=> {
  try {
    const fixedPriceSellOrder = await seaport.createSellOrder({
      asset: {
        tokenId: req.body.tokenId,
        tokenAddress: req.body.contractAddress,
      },
      startAmount: req.body.startAmount,
      expirationTime: req.body.expirationTime,
      accountAddress: req.body.ownerAddress,
    });
    console.log(`Successfully created a fixed-price sell order! ${fixedPriceSellOrder.asset.openseaLink}\n`);
    res.send(fixedPriceSellOrder);
  } catch (error) {
    return next(error);
  }
});

const port = process.env.PORT || 13579;
app.listen(port, () => console.log(`Service is listening on port ${port}..`));

但是，这会导致错误（我怀疑错误消息是否相关，但仍然共享它）：

我要说的一点是，当我将第一个清单中的相同功能转移到 POST 处理程序时，它现在失效了，所以我怀疑它与 OpenSea SDK 被破坏有什么关系。

错误消息非常相关。 错误消息是Error: No wallet address found 。 这意味着处理钱包地址的任何参数，最有可能设置为accountAddress的req.body.ownerAddress是 null 或无效。

我会仔细检查您的请求正文中的值，因为它们是可能的原因。
