Question

我在tomcat8上使用了swagger ui实例。它会加载一个.yaml文件，该文件描述了一个摇头规格。一切正常，当我尝试使用“尝试”功能时，它将向服务器发送一个http请求并给出

TypeError: Failed to fetch

回来。在我的服务器上，我已通过

启用了CORS

    import java.io.IOException;

import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.ext.Provider;

    @Provider
    public class CORSFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, 
      ContainerResponseContext responseContext) throws IOException {
          responseContext.getHeaders().add(
            "Access-Control-Allow-Origin", "http://localhost:8080");
          responseContext.getHeaders().add(
            "Access-Control-Allow-Credentials", "true");
          responseContext.getHeaders().add(
           "Access-Control-Allow-Headers",
           "origin, content-type, accept, authorization");
          responseContext.getHeaders().add(
            "Access-Control-Allow-Methods", 
            "GET, POST, PUT, DELETE, OPTIONS, HEAD");
       }
    }

，并且在浏览器中输入了正确的证书。通过浏览器成功发送相同的请求（通过摇晃发送），并给出正确的响应。

编辑：刚刚发现我收到以下错误

Fetch API cannot load https://localhost:8184/user/info?username=mustermann. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

如何在Swagger / UI中启用CORS？在服务器站点上应启用它。

我想念什么吗？
