我的Zuul过滤器的一个请求是URI / hello / World ,我想重定向到 / myapp / test 即可。此/ myapp / test是在Eureka注册的服务。
zuul:
routes:
xyz:
path: /hello/World
url: http://localhost:1234/myapp/test
stripPrefix: true
当我尝试上述配置时,传入的URI会作为配置的URL的后缀,如 http://localhost:1234/myapp/test/World 。我遇到的链接似乎很少说明在Zuul中尚未提供URL重写功能。
还有其他方法可以在Zuul层完成吗?
注意:此时,我无法在Web服务器或任何其他层执行此反向代理,因为我的Zuul过滤器是直接接收请求的过滤器。

这是@Vikash链接中的已发布解决方案
@Component
public class CustomPathZuulFilter extends ZuulFilter
{
@Override
public String filterType() {
return "pre";
}
@Override
public int filterOrder() {
return PreDecorationFilter.FILTER_ORDER + 1;
}
@Override
public boolean shouldFilter() {
return true;
}
@Override
public Object run() {
RequestContext context = RequestContext.getCurrentContext();
Object originalRequestPath = context.get(REQUEST_URI_KEY);
String modifiedRequestPath = "/api/microservicePath" + originalRequestPath;
context.put(REQUEST_URI_KEY, modifiedRequestPath);
return null;
}
}

使用@Adelin解决方案,几乎没有改善
使用'url'属性作为添加自定义Url重写的路径(在我的示例中,我禁用了Eureka):
ribbon.eureka.enabled=false
zuul.routes.route1.path=/route1/**
zuul.routes.route1.serviceId=service1
zuul.routes.route1.url=/path/to/prepend
service1.ribbon.listOfServers=http://server1
然后实施以下过滤器:
/**
* Fixing missing URL rewriting when using ribbon
*/
@Component
public class CustomPathZuulFilter extends ZuulFilter {
@Autowired
private ZuulProperties zuulProperties;
@Override
public String filterType() {
return FilterConstants.PRE_TYPE;
}
@Override
public int filterOrder() {
return FilterConstants.PRE_DECORATION_FILTER_ORDER + 1;
}
@Override
public boolean shouldFilter() {
// override PreDecorationFilter only if executed previously successfully
return RequestContext.getCurrentContext().getFilterExecutionSummary().toString()
.contains("PreDecorationFilter[SUCCESS]");
}
@Override
public Object run() {
final RequestContext context = RequestContext.getCurrentContext();
if (context.get(FilterConstants.SERVICE_ID_KEY) == null || context.getRouteHost() != null) {
// not a Ribbon route
return null;
}
// get current ZuulRoute
final String proxy = (String) context.get(FilterConstants.PROXY_KEY);
final ZuulRoute zuulRoute = this.zuulProperties.getRoutes().get(proxy);
// patch URL by prefixing it with zuulRoute.url
final Object originalRequestPath = context.get(FilterConstants.REQUEST_URI_KEY);
final String modifiedRequestPath = zuulRoute.getUrl() + originalRequestPath;
context.put(FilterConstants.REQUEST_URI_KEY, modifiedRequestPath);
// patch serviceId because :
// - has been set to route.location in PreDecorationFilter
// - route.location has been set to zuulRoute.location in SimpleRouteLocator
// - zuulRoute.location return zuulRoute.url if set
context.set(FilterConstants.SERVICE_ID_KEY, zuulRoute.getServiceId());
return null;
}
}
现在对 / route1 的呼叫将被代理为 http://server1/path/to/prepend
此解决方案还与不使用功能区的共存路由兼容。
不使用功能区的共存路由示例:
zuul.routes.route2.path=/route2/**
zuul.routes.route2.url=http://server2/some/path
对 / route2 的调用将由SimpleHostRoutingFilter(如果未禁用)代理为 http://server2/some/path
