useEffect 中的 setState 取决于 props.location.state，不起作用

Question

我不明白我在这里遗漏了什么，非常感谢您的帮助！

我正在通过命令 history.push (urlState) 从另一个功能组件进入我的“测试”功能组件。

"urlState" 是一个对象，我在 "Test" 组件的 useEffect 函数中检查它的值。

根据 urlState 中的值，我决定是否执行“setRequestNumber”和“setRequestSubNumber”，以及向它们发送哪些值。

但是set函数不起作用！！

我做错了什么？？

（我希望 useEffect 只运行一次，所以我将依赖项数组留空。）

这是我的代码-

import React, { useState, useEffect } from "react";
import {URL} from "../../config/Constants"

const Test = (props) => {
  const [requestNumber, setRequestNumber] = useState(0);
  const [requestSubNumber, setRequestSubNumber] = useState(1);

  const getRequestDetails = async (fetchURL) => {
    try {
      const response = await fetch(fetchURL);
      if (!response.ok) {
        throw new Error("something went wrong!");
      }
      const body = await response.json();
      const result = body.results;
      console.log(result); //result will be rendered instead of <h1>Hi there!</h1>
    } catch (error) {}
  };

  const getNextRequestCounter = async () => {
    try {
      const response = await fetch(`${URL}/requests/requestCounter`);
      if (!response.ok) {
        throw new Error("something went wrong!");
      }
      const body = await response.json();
      const result = body.results[0];
      setRequestNumber(result);
    } catch (error) {
    }
  };
  useEffect(() => {
    var urlState = {
      request: 1,
      subRequest: 2,
      isNewRequest: false,
      originalSubRequest: 1,
    }; // That what I have in props.location.state;
    
    var fetchURL = "";
    if (urlState.isNewRequest) {
      getNextRequestCounter();
      fetchURL = `${URL}/requests/${requestNumber}/${requestSubNumber}`;
    } else {
      setRequestNumber(urlState.request);
      setRequestSubNumber(urlState.subRequest);
      fetchURL = `${URL}/requests/${requestNumber}/${urlState.originalSubRequest}`;
    }
    getRequestDetails(fetchURL);
  }, []);
  return <h1>Hi there!</h1>;
};
export default Test;

谢谢！
