序
除了修改请求参数、设置响应header，响应body外，还有一种需求就是url重新，或者是修改url，这里简述一下怎么在zuul修改url。
转发配置
demo:
ribbon:
NIWSServerListClassName: com.netflix.loadbalancer.ConfigurationBasedServerList
listOfServers: 192.168.99.100,192.168.99.101
zuul:
routes:
demo:
path: /demo/**
stripPrefix: true
serviceId: demo
filter配置
@Component
public class UrlPathFilter extends ZuulFilter{
@Override
public String filterType() {
return FilterConstants.PRE_TYPE;
}
@Override
public int filterOrder() {
return FilterConstants.PRE_DECORATION_FILTER_ORDER + 1;
}
@Override
public boolean shouldFilter() {
final String serviceId = (String) RequestContext.getCurrentContext().get("proxy");
return "demo".equals(serviceId);
}
@Override
public Object run() {
RequestContext context = RequestContext.getCurrentContext();
Object originalRequestPath = context.get(FilterConstants.REQUEST_URI_KEY);
//http://localhost:10000/demo/list/data
//-->/api/prefix/list/data
String modifiedRequestPath = "/api/prefix" + originalRequestPath;
context.put(FilterConstants.REQUEST_URI_KEY, modifiedRequestPath);
return null;
}
}
这样就大功告成了
