我正在尝试发出一个GET请求,这可以通过POSTMAN正常工作,但是反应似乎不起作用。
出于某种原因,尽管存在CORS错误,它也会返回数据。如何解决?
index.js(Redux设置)
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import App from './App';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import ReduxPromise from 'redux-promise';
import thunk from 'redux-thunk';
import createHistory from 'history/createBrowserHistory'
import { ConnectedRouter, routerReducer, routerMiddleware, push } from 'react-router-redux'
import {assumeRole} from './libs/awsLib';
import './index.css';
import reducers from './reducers';
import {LOGIN, LOGOUT} from "./actions/UsersActions";
import {api} from "./actions/api";
const history = createHistory();
const myRouterMiddleware = routerMiddleware(history);
const createStoreWithMiddleware = applyMiddleware(ReduxPromise, thunk, myRouterMiddleware)(createStore);
ReactDOM.render(
<Provider store={createStoreWithMiddleware(reducers)}>
<ConnectedRouter history={history}>
<App />
</ConnectedRouter>
</Provider>,
document.getElementById('root')
);
FileListReducer
import {GET_DOCUMENTS} from "../actions/index";
export default function(state = [], action) {
//reducers should return a new object, never mutate the current state
switch (action.type) {
case GET_DOCUMENTS:
return action.payload;
}
return state;
}
FilesActions
import 'whatwg-fetch'
import {api} from './api';
import config from '../config.js';
export const GET_DOCUMENTS = 'GET_DOCUMENTS';
export function getDocuments() {
return (dispatch) => {
const request = api.fetch('warpig/document/?userId='+localStorage.getItem("id")).then((res) => {
dispatch({
type: GET_DOCUMENTS,
payload: {data: res, success: res.status == 200}
})
}, (err, data) => {
console.log(err, data);
});
}
}
我的方式来调用getDocuments()
...
componentDidMount() {
this.getDocuments();
}
getPrograms() {
this.props.fetchPrograms();
}
...
function mapDispatchToProps(dispatch) {
return bindActionCreators({ fetchPrograms, uploads3, login, assignToken, getDocuments }, dispatch);
}
function mapStateToProps({ programs, fileUpload, auth, filesList }) {
return { programs, fileUpload, auth, filesList };
}
export default connect(mapStateToProps, mapDispatchToProps)(FileUpload)
主要问题是通过POSTMAN工作,但是当我通过React在我的浏览器上发出HTTP GET请求时,尽管它返回了数据,但是,它可能是什么?
