Redux-Saga与Redux-Thunk对比

⭐ 核心区别对比表

🌟 实现原理详解

Redux-Thunk

// Redux-Thunk核心实现(仅10行左右)
function createThunkMiddleware(extraArgument) {return ({ dispatch, getState }) => next => action => {if (typeof action === 'function') {return action(dispatch, getState, extraArgument);}return next(action);};
}

// 使用Redux-Thunk的异步Action
const fetchUser = (userId) => {// 返回一个函数而非普通action对象return async (dispatch, getState) => {dispatch({ type: 'FETCH_USER_START' });try {const response = await fetch(`/api/users/${userId}`
