Question

我正在尝试使用axios渲染从API提取的数据，但屏幕上没有任何渲染。请注意，数据实际上是可用的，如控制台日志中所示。这是代码和我尝试过的内容。

create or replace
algorithm = UNDEFINED view `all_testi_view` as (
select
    `all_testi_with_sub_typ`.`TEXT_ID` as `TEXT_ID`,
    `all_testi_with_sub_typ`.`NOME_AUTORE` as `NOME_AUTORE`,
    `all_testi_with_sub_typ`.`TIPOLOGIA` as `TIPOLOGIA`,
    `all_testi_with_sub_typ`.`SUB_TIPOLOGIA` as `SUB_TIPOLOGIA`,
    `all_testi_with_sub_typ`.`TESTO` as `TESTO`,
    `all_testi_with_sub_typ`.`COMMENTO` as `COMMENTO`,
    `all_testi_with_sub_typ`.`DATA_EVENTO` as `DATA_EVENTO`,
    `all_testi_with_sub_typ`.`COUNTER` as `COUNTER`
from
    `all_testi_with_sub_typ`)
union (
select
`all_testi_without_sub_typ`.`TEXT_ID` as `TEXT_ID`,
`all_testi_without_sub_typ`.`NOME_AUTORE` as `NOME_AUTORE`,
`all_testi_without_sub_typ`.`TIPOLOGIA` as `TIPOLOGIA`,
`all_testi_without_sub_typ`.`SUB_TIPOLOGIA` as `SUB_TIPOLOGIA`,
`all_testi_without_sub_typ`.`TESTO` as `TESTO`,
`all_testi_without_sub_typ`.`COMMENTO` as `COMMENTO`,
`all_testi_without_sub_typ`.`DATA_EVENTO` as `DATA_EVENTO`,
`all_testi_without_sub_typ`.`COUNTER` as `COUNTER`
from
`all_testi_without_sub_typ`)

为什么搜索查询结果没有显示在屏幕上，我该如何继续？

Answer 1

电影被定义为一个数组，显然是数据。搜索也是一个数组。
您需要遍历电影数组以获得有关每个电影的数据。
像这样：

  return (
    <div>
      <input
        type="text"
        value={query}
        onChange={(e) => {
          setQuery(e.target.value);
        }}
      />
      <button onClick={handleClick}>Fetch movies</button>
      <div>{movie.map((el)=>el.Title)}</div>
    </div>
  );

为什么useState不呈现API响应？
