javascript - TypeError：从 API 获取时无法读取未定义的属性“地图”

问题描述

我一直在尝试进行简单的 API 获取，但我不明白我做错了什么我已经阅读了很多问题，但我真的觉得我错过了一些东西，因为一切似乎都是正确的（显然不是）

import { useState } from "react";
import ProductCard from "./ArticleCard/ProductCard.js";

export default function ProductsIndex() {
  const [searchText, set_searchText] = useState("");
  const [state, set_state] = useState({ status: "idle" });
  const search = async () => {
    if (searchText === "") {
      set_state({ status: "idle" });
      return;
    }
    set_state({ status: "searching" });
    const queryParam = encodeURIComponent(searchText);
    const data = await fetch(
      /* base browser fetch  https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch*/
      `https://omdbapi.com/?apikey=6a06f383&s=${queryParam}`
    ).then((r) => r.json());
    set_state({ status: "done!", data: data.Search });
  };
  console.log(state.data);
  return (
    <div className="ProductsIndex">
      We sell movies for a high price.
      <h1>Discover some movies!</h1>
      <p>
        <input
          value={searchText}
          onChange={(e) => set_searchText(e.target.value)}
        />
        <button onClick={search}>Search</button>
      </p>{" "}
      <p>
        {state.data.map((movie) => (
          <ProductCard
            poster={movie.poster}
            title={movie.title}
            year={movie.year}
            type={movie.type}
          />
        ))}
      </p>
    </div>
  );
}

console.log(state.data) 给出了想要的结果，所以就好像数据没有被传递下去..我不明白为什么

来自 console.log(state.data) 的结果：

[

        "Title": "Finding Nemo",
