XMLHttpRequest无法在请求的资源上加载“访问-控制-允许-原产地”标头。Http://localhost:3000‘谷歌地图
提问于 2017-04-08 12:45:24
我是新的反应js，我试图简单动态地改变地图与尊重的用户输入，但对于特定的地方seach请求，这个错误上升。
XMLHttpRequest无法加载https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=undef…ined&radius=1000&keyword=fdtbf&key=myapikey。请求的资源上没有“访问-控制-允许-原产地”标题。因此，“http://localhost:3000”源是不允许访问的。
这是我的节点js代码
import express from 'express';
import path from 'path';
import bodyParser from 'body-parser';
//Import To Pord
import api from './routes/api';

let app = express();
app.use(bodyParser.json());
app.use(express.static('public'))
const compiler = webpack(webpackConfig);
app.use(webpackMiddleware(compiler, {

}));
app.use(webpackHotMidleware(compiler));
app.use(cors());
app.use(cookieParser('sdkhcvlsd684684JJJklvblsdkuvgblsduvblsidvksdjbvlsjvuywlsfvliusdgv'));

app.get('/*', (req, res,next) => {

// Server Side Rendering Starts
match({routes:routes(),location:req.url},(err,redirectLocation,renderProps) => {

if (redirectLocation) {
return res.redirect(302, redirectLocation.pathname + redirectLocation.search)
}
// if (!renderProps) {

// }
const components = renderProps.components;
const Comp = components[components.length - 1].WrappedComponent;
const fetchData = (Comp && Comp.fetchData) || (() => Promise.resolve())
const initialState = {}
const store = createStore(reducer, initialState, applyMiddleware(thunk));
const { location, params, history } = renderProps
fetchData({ store, location, params, history }).then(() => {
const body = renderToString(
<Provider store={store}>
<RouterContext {...renderProps} />
</Provider>
)
const state = store.getState();
// console.log(state)
let head = Helmet.rewind();
res.header('Access-Control-Allow-Origin', "*");
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers', 'Content-Type');
res.send(`<!DOCTYPE html>

<script>window.__STATE__=${JSON.stringify(state)}</script>

</body>
</html>`)
})
.catch((err) => next(err))
})
});
app.listen(3000 ,() => {
console.log('Listening')
});这是我的axios请求
export function getPlaceFromCoords(term,coords) {
// https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=13.0826802,80.2707184&radius=500&keyword=parks&key=AIzaSyAZbur2hq7p3UxjYrA2_G4ctpswFi0pO3A
console.log(coords)
return dispatch => {
return axios.get(`https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=${coords.lat},${coords.lng}&radius=1000&keyword=${term}&key=${config.MAP_API}`).then(response => {
return response.data
})
}

CORS头没有为Google后端服务器上的Places服务设置。因此，由于浏览器的相同来源策略，您将无法从客户端JavaScript代码调用Places服务。
为了使用客户端JavaScript上的位置，您必须使用Google API的Places。地点库的附近、雷达和文本搜索功能非常类似于相应的web服务。
欲知更多详情，请参阅下列文件：
