@CrossOrigin

@CrossOrigin is a Spring annotation that allows for cross-origin resource sharing (CORS) in web applications. It is used to enable communication between a client-side application and a server-side application that are hosted on different domains. CORS is a security feature that restricts web pages from making requests to a different domain than the one that served the web page. By using @CrossOrigin, developers can specify which domains are allowed to make requests to their server-side application, thus enabling cross-domain communication. This annotation can be applied to a controller class or method to enable CORS for that specific endpoint.

@crossorigin
@crossorigin 是一个 HTML 和 JavaScript 中的属性,用于指定跨域请求时是否允许携带凭证(如cookie、HTTP认证及客户端SSL证明等)。它可以设置为 "anonymous" 或 "use-credentials"。其中 "anonymous" 表示不允许携带凭证,而 "use-credentials" 表示允许携带凭证。在一些情况下,比如跨域 AJAX 请求,需要设置 @crossorigin 属性以进行跨域访问。
@CrossOrigin作用
`@CrossOrigin`是一个Spring WebFlux或Spring MVC中的注解,用于处理跨域资源共享(Cross-Origin Resource Sharing, CORS)。它允许特定的JavaScript代码访问来自其他源的Web资源,通常是因为浏览器的安全策略(同源策略)限制了这种交互。
当你在一个API端点上应用`@CrossOrigin`,例如:
```java
@GetMapping("/api/data")
@CrossOrigin(allowedOrigins = "*", allowCredentials = true)
public Mono<DataResponse> getData() {
// 数据获取逻辑...
}
```
这个注解告诉浏览器和服务器,这个特定的GET请求可以接受任意来源的请求头,并允许发送凭据(如cookies),这对于需要身份验证的跨域请求特别重要。`allowedOrigins`属性指定了哪些域名可以发起请求,这里的"*"表示所有。
