Javascript 如何将参数传递到Redux中间件？

我想将一个参数传递到自定义Redux中间件中。 但是我不知道如何在自定义中间件中使用参数

例如：

import { createStore, applyMiddleware } from 'redux';
import reducers from './reducers';

const customMiddleWare = store => next => action => {
  // how to use argument here?
};

const middlewares = [customMiddleWare(argument)];

const store = createStore(
  reducers,
  applyMiddleware(...middlewares)
);

const middlewareWrapper = customArgument => store => next => action =>
  console.log(customArgument);
}

const middlewares = [middlewareWrapper(argument)];

const store = createStore(
  reducers,
  applyMiddleware(...middlewares)
);

由于中间件是函数，您可以创建一个包装器函数，该函数将接受您的参数并返回您的中间件函数，该函数将访问提供的参数

例如：

import { createStore, applyMiddleware } from 'redux';
import reducers from './reducers';

const customMiddleWare = store => next => action => {
  // how to use argument here?
};

const middlewares = [customMiddleWare(argument)];

const store = createStore(
  reducers,
  applyMiddleware(...middlewares)
);

const middlewareWrapper = customArgument => store => next => action =>
  console.log(customArgument);
}

const middlewares = [middlewareWrapper(argument)];

const store = createStore(
  reducers,
  applyMiddleware(...middlewares)
);

你具体想做什么？您已经在向

customMiddleWare

传递一个参数，但它不是您认为的那个参数。不确定您的实际用例是什么，但一般来说，中间件不是这样构造的。@DaveNewton您是对的，我更新了这个问题。
