如何检查React Saga中API post的成功/错误

// saga.js

import { put, takeLatest } from "redux-saga/effects";
import { postApi } from "./api"; // 导入封装的API post请求方法
import { postSuccessAction, postErrorAction } from "./actions"; // 导入成功和错误的action

function* postSaga(action) {
  try {
    const response = yield postApi(action.payload); // 调用API post请求
    yield put(postSuccessAction(response.data)); // post请求成功，派发成功的action
  } catch (error) {
    yield put(postErrorAction(error.message)); // post请求错误，派发错误的action
  }
}

export function* watchPost() {
  yield takeLatest("POST_REQUEST", postSaga); // 监听post请求的action
}

// actions.js

export const postSuccessAction = (data) => ({
  type: "POST_SUCCESS",
  payload: data,
});

export const postErrorAction = (error) => ({
  type: "POST_ERROR",
  payload: error,
});

// reducer.js

const initialState = {
  data: null,
  error: null,
};

const postReducer = (state = initialState, action) => {
  switch (action.type) {
    case "POST_SUCCESS":
      return {
        ...state,
        data: action.payload,
        error: null,
      };
    case "POST_ERROR":
      return {
        ...state,
        data: null,
        error: action.payload,
      };
    default:
      return state;
  }
};

export default postReducer;
