集成redux-form和redux-observable可以通过以下步骤完成:
import { createStore, applyMiddleware, combineReducers } from 'redux';
import { createEpicMiddleware } from 'redux-observable';
import { reducer as formReducer } from 'redux-form';
import { combineEpics } from 'redux-observable';
const formEpic = (action$, state$) =>
action$.pipe(
ofType('SUBMIT_FORM'), // 替换为你的表单提交action类型
mergeMap(action => {
// 在这里处理表单提交的逻辑
// 可以使用ajax请求发送表单数据到服务器
return ajax.post('/api/submit', action.payload).pipe(
map(response => ({
type: 'SUBMIT_FORM_SUCCESS',
payload: response
})),
catchError(error => ({
type: 'SUBMIT_FORM_ERROR',
payload: error
}))
);
})
);
const rootEpic = combineEpics(formEpic); // 将所有的epic合并成一个根epic
const epicMiddleware = createEpicMiddleware();
const rootReducer = combineReducers({
form: formReducer, // 将redux-form的reducer加入到根reducer中
// 其他的reducer...
});
const store = createStore(
rootReducer,
applyMiddleware(epicMiddleware)
);
epicMiddleware.run(rootEpic); // 运行根epic
import React from 'react';
import { Field, reduxForm } from 'redux-form';
const MyForm = props => {
const { handleSubmit } = props;
const onSubmit = values => {
// 在这里触发表单提交的action
props.submitForm(values);
};
return (
<form onSubmit={handleSubmit(onSubmit)}>
<div>
<label htmlFor="name">Name</label>
<Field name="name" component="input" type="text" />
</div>
<div>
<label htmlFor="email">Email</label>
<Field name="email" component="input" type="email" />
</div>
<button type="submit">Submit</button>
</form>
);
};
const ConnectedForm = reduxForm({
form: 'myForm' // 替换为你的表单名称
})(MyForm);
export default ConnectedForm;
在上述代码中,我们使用redux-form的reduxForm高阶组件将表单组件连接到Redux的store,并使用handleSubmit函数来处理表单的提交。在onSubmit函数中,我们可以调用props.submitForm来触发表单提交的action。
这样,就完成了redux-form和redux-observable的集成。当用户提交表单时,redux-observable的epic会捕获到相应的action,并处理表单提交的逻辑。你可以根据具体的业务需求,自定义epic中的逻辑。
