IPhone Chrome&iphone UC Browser Jsonp accept Bug & h5 access-control-allow-origin cross-domain

In the Chrome and UC browsers of the iphone, when JSONP is used across domains, the request's accept will be: */*;IMAGE/WEBP.

When there is no special handling of content-type on the backend, the IMAGE/WEBP will be returned directly, and chrome and UC will not be able to perform the JS returned by JSONP.

Solution:

1, abandon the Jsonp form cross-domain, instead of setting access-control-allow-origin

2. When a cookie is required to cross a domain,

Back-end settings:

Access-control-allow-credentials:true,

Ajax settings:

Xhrfields: {
Withcredentials:true
}

It is important to note that Access-control-allow-origin cannot be set to * at this time

Otherwise the error is as follows:

XMLHttpRequest Cannot load Http://api.d.driver.edaijia.cn/workbench/userInfo?appkey=51000031&ver=3&met ... 11:16&ssid=u8srbnhpv2cogetnvaudrb3974&sig=61be8551eb4f8a8e3007ef748602df5e. A Wildcard ' * ' cannot be used in the ' Access-control-allow-origin ' header when the credentials flag is true. Origin ' http://h5.d.edaijia.cn ' is therefore not allowed access.
