javascript – 警告：propType失败：使用React的类型为`array` expected`object`的prop

因此,这行代码抛出的内容类似于“Failed propType：类型数组预期对象的无效prop”.

为什么会这样？@H_675_3@

这是我的JSON：@H_675_3@

"student_records": [
      {
        "program": "PSCI-210","grade": 80
      }
    ]

JSX：@H_675_3@

import React,{ PropTypes } from 'react';


const studentRecordPropTypes = {
  studentRecordData: PropTypes.object.isrequired,};

function studentRecord(props) {
    const Records = props.studentRecordData;


  return (
    <div>
        {(Records || []).map(student_records => (
              <ul>
                    <li>{student_records.program} : {student_records.gradE} </li>
              </ul>
            ))}
    </div>
  );
}
studentRecord.propTypes = studentRecordPropTypes;

export default studentRecord;

它显示正确.经过一些谷歌搜索,我意识到它寻找一个数组,但它实际上是一个对象.我的问题是我不知道如何解决它.如何删除此错误？@H_675_3@

const studentRecordPropTypes = {
  studentRecordData: PropTypes.object.isrequired,};

const studentRecordPropTypes = {
  studentRecordData: PropTypes.array.isrequired,};
