我正在使用fetch polyfill和'no-cors'模式并获得响应状态0.在开发人员工具中,我可以看到响应具有所请求的数据.
客户端代码:
const BASE_CONFIG = {
credentials: 'include',
mode: 'no-cors'
};
let checkStatus = (response) => {
if (response.status >= 200 && response.status < 300) {
return response;
} else {
var error = new Error(response.statusText);
error.response = response;
throw error;
}
};
function GET(url, urlParams={}, config={}) {
let requestConfig = {
method: 'get'
};
Object.assign(requestConfig, BASE_CONFIG, config);
return fetch(url, requestConfig)
.then(checkStatus)
.then(parseJSON);
}
GET('http://other.domain,{})Beckend nodejs(Express.js)简化的响应处理程序:
function getData(req, res) {
var responseData = {data: 'test'};
res.header("Access-Control-Allow-Origin", "*"); …
