If the web service URL has a different host (by domain name or port) than the one from which the HTML page is served then your JavaScript is violating the same origin policyand any browser will prevent the web service request from loading.
如果 Web 服务 URL 的主机（按域名或端口）与提供 HTML 页面的主机不同，则您的 JavaScript 违反了同源策略，任何浏览器都将阻止加载 Web 服务请求。
