问题 Shortly: Is there any way to make a cross origin request for an image with the background-image property in CSS. I need something like the crossOrigin property for the img tag, but in CSS. I am running into a problem because chrome caches the response without CORS headers, and then later, when an <img> tag uses the same source I get a cross-origin error because it is using the cached response that doesn't have the necessary CORS headers. 回答1: Check this API. I guess you need to configure your

问题 Why is my 'Access-Control-Allow-Credentials' no longer being sent in response to preflight calls (OPTIONS) under Spring Boot 2.0.x (2.0.1.RELEASE in my case)? Here is my Global CORS Configuration that works fine under Spring Boot 1.5.6: @Configuration public class CorsConfig { @Bean public WebMvcConfigurer corsConfigurer() { return new WebMvcConfigurerAdapter() { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowedOrigins( "http://localhost:3000",

问题 I've tried everything to get around the CORS error I am receiving. For oauth flow, to redirect your app to the Salesforce login screen (but this url auto redirects behind the scenes from salesforce to salesforce) XMLHttpRequest cannot load salesforce url 2 Redirect from salesforce url 1 to salesforce oauth url 2 has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
