golang prohibits cross-domain
Article Introduction:As web application development becomes more and more complex, cross-domain issues become more common. Cross-domain means that in a browser, a web page cannot directly access resources or data under another domain name. This security restriction is the basic security mechanism of the browser. However, in some cases, it is necessary to allow cross-domain resource sharing between different domain names, because some applications need to obtain resources under other domain names to implement functions. As an emerging language, golang's built-in http package also provides support for cross-domain resource sharing. This article will explore how to use g

How to configure cross-domain filters in SpringBoot to allow cross-domain access
Article Introduction:SpringBoot cross-domain filter configuration allows cross-domain access Cross-domain requests When a resource requests a resource from a different domain or port than the server where the resource itself resides, the resource initiates a cross-domain HTTP request. For security reasons, browsers restrict cross-origin HTTP requests initiated from within scripts. For example, XMLHttpRequest and FetchAPI follow the same-origin policy. This means that web applications using these APIs can only request HTTP resources from the same domain where the application is loaded, unless CORS headers are used. Problem background: If the front end prompts "Access-Control-Allow-Origin" problem XMLHttpRequestcann

location.hash cross-domain solution principle
Article Introduction:When we request resources from a web page in one domain name to another domain name, the browser will send a preflight request to the server to determine whether the server supports cross-domain requests. After the server receives the preflight request, it can determine whether the cross-domain request is allowed based on the request header information. If it is allowed, it will return the corresponding response header, allowing the browser to make the cross-domain request successfully.
