序
除了修改請(qǐng)求參數(shù)旦万、設(shè)置響應(yīng)header棋恼，響應(yīng)body外湘纵，還有一種需求就是url重新脂崔，或者是修改url，這里簡(jiǎn)述一下怎么在zuul修改url梧喷。
轉(zhuǎn)發(fā)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;
}
}
這樣就大功告成了
