我希望有人能帮助我确定我在代码中做错了什么。
该应用程序是一个使用新APP目录和NextJS的Employee Search。

Works:过滤和捕获用户输入的输入字段。API端点返回JSON。
不起作用:如果我在/header/page中包含<SearchResults query={query} />语句。js代码,然后代码连续运行API获取,直到我删除该语句并再次编译。

我会清理一些代码,一旦我有它的工作,但我做错了什么?
/header/page.js

'use client'
import { useState } from 'react';
import Header from './header/page.js';
import SearchText from './search-text/page.js';
//import SearchResults from './search-results/page.js';

export default function Home() {
  const [query, setQuery] = useState('');

  return (
    
    <>
      
      <Header />
      <SearchText 
         query={query} 
         onQueryChange={setQuery} />
      
      
    </>

  )
}

/search-text/page.js

export default function SearchText({ query, onQueryChange }) {
  
  return (
      
    <>
      
      <form id='EmployeeSearchText'>
        <div className="container-fluid p-3">
          <div id='Row1' className={`row ${utilStyles.divPadding}`}>

尝试在获取数据时添加UseEffect
在你的第三个代码片段中,尝试这样做:

import utilStyles from '/styles/utils.module.css';
import { faPhone, faEnvelope } from '@fortawesome/free-solid-svg-icons';
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { useEffect, useState } from 'react';

export default async function SearchResults( {query} ) {

  const [employees, setEmployees] = useState([]);

  useEffect(()=>{
      async function getEmployees() {
        const res = await fetch('https:xxxxxx?searchinput=${query}');
    
        const directory = await res.json();
        return directory;
      }
      console.log({query});
      const data = await getEmployees();
      setEmployees(data);
  }, [])
  
  const emp = employees.map((employee, index, array) => {
    
    return (
        
      <div className="col col-12 col-sm-6 col-xl-4 mb-4">
        <div className="col-12 mb-4">
          <div className={`card ${utilStyles.cardBody}`}>
            <div className="card-body">
              <div className={`${utilStyles.ribbonLight} ${utilStyles.ribbonBottomRight}`}><span>{employee.CAMPUS}</span></div>
              <h3 className="card-title card-name">{employee.NAME}</h3>
              <h5 className={`${utilStyles.cardSubtitle} ${utilStyles.cardJobtitleNew} mb-2`}>{employee.JOBTITLE}</h5>
              <p className={`${utilStyles.cardText} ${utilStyles.cardDepartment}`}>{employee.DEPARTMENT}</p>
              <div>
                <p className={utilStyles.cardTextBottom}><FontAwesomeIcon icon={faPhone} className={utilStyles.cardTextIcons} /><span className={utilStyles.cardPhoneEmail}>W:</span>{employee.PHONE}</p>
                <p className={utilStyles.cardTextBottom}><FontAwesomeIcon icon={faEnvelope} className={utilStyles.cardTextIcons} /><span className={utilStyles.cardPhoneEmail}>W:</span></p>
              </div>
            </div>
          </div>
        </div>
      </div>
    
    )
      
  });
  
  return (
    
    <div className="container">
      <div className="row">{emp}</div>
    </div>
       
  );
}
