我正在使用Nextjs，并从Coindesk的API获取比特币的当前价格：
第一个月
我在Home组件中获取了数据，在这个组件中，我得到了正确的json数据。我将此数据作为prop发送到Prices组件，但它在此组件中没有正确记录。axios是否有问题？
下一篇：bpi: { USD: {...}, GBP: {...}, EUR: {...} }
我得到了这个：bpi: { USD: [Object], GBP: [Object], EUR: [Object] }
Home.js

import Layout from "../components/Layout"
import Prices from "../components/Prices"
import axios from "axios"

const Home = (props) => {
  return (
    <Layout>
      <div>
        <h1>Welcome to Bitzprice</h1>
        <Prices bpiData={props.bpiData} />
      </div>
    </Layout>
  )
}

Home.getInitialProps = async function () {
  const res = await axios.get(
    "https://api.coindesk.com/v1/bpi/currentprice.json"
  ) 
  const data = res.data
  console.log("DATA=>", data)
  return {
    bpiData: data,
  }
}

export default Home

价格.js

class Prices extends React.Component {
  state = {
    currency: "USD",

  render() {

    return (
      <div>
        ....
      </div>
    )
  }
}

export default Prices
