如何在我的 java fie 中添加跨源资源共享

Question

我写的不对

HttpClient httpClient = HttpClientBuilder.create().header("Access-Control-Allow-Origin", "*")
                .header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT")
                .allow("OPTIONS").build();

Answer 1

您可以为 CORS 源过滤器编写组件 class

 @Component
public class CorsFilterConfiguration implements Filter {
    public void doFilter(ServletRequest req, ServletResponse res,
                         FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, PATCH, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, Content-Type, authToken"); //TODO: Fix 'token' to 'OAuth' / 'SAML' header.
        chain.doFilter(req, res);
    }
    public void init(FilterConfig filterConfig) {
    }
    public void destroy() {
    }
}
