我新的反應，我想簡單的動態變化圖與尊重用戶的輸入，但對於具體的地方SEACH要求這個錯誤上升的XMLHttpRequest不能加載否「訪問控制允許來源」標題存在於所請求的資源。原產地的「http：//本地主機：3000」谷歌地圖
JS的XMLHttpRequest不能負載 https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=undef ... INED &半徑= 1000 &關鍵字= fdtbf &鍵= myapikey。 請求的 資源上沒有「Access-Control-Allow-Origin」標題。原因'http://localhost:3000'因此不允許 訪問。
這是我的節點js代碼

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 state = store.getState();
// console.log(state)
let head = Helmet.rewind();
res.header('Access-Control-Allow-Origin', "*");

})
.catch((err) => next(err))
})
});
app.listen(3000 ,() => {
console.log('Listening')
});
這是我的愛可信要求
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
})
}
}
向後端傢伙來實現CORS。與反應無關。 – Ved
我用這個中間件** app.use（CORS（））; **但是沒有用 – Nane
您需要檢查正常。但它都是後端的東西。沒有Reactjs問題。 – Ved
