## zuul过滤器 |
演示在网关追加一个header |
||||||
|
|
||||||
zuul过滤器列表如下： |
|
||||||
|
|
||||||
| 类型 | 顺序 | 过滤器 | 功能 | |
|
||||||
| ----- | ---- | ----------------------- | ---------------------------- | |
|
||||||
| pre | -1000 | PreValidateFilter (SOP自带) | 校验签名 | |
|
||||||
| pre | -998 | PreLimitFilter (SOP自带) | 限流拦截器 | |
|
||||||
| pre | -3 | ServletDetectionFilter | 标记处理 Servlet 的类型 | |
|
||||||
| pre | -2 | Servlet30WrapperFilter | 包装 HttpServletRequest 请求 | |
|
||||||
| pre | -1 | FormBodyWrapperFilter | 包装请求体 Servlet30WrapperFilter | |
|
||||||
| pre | 1 | DebugFilter | 标记调试标志 | |
|
||||||
| pre | 5 | PreDecorationFilter | 决定路由转发过滤器 | |
|
||||||
| route | 10 | RibbonRoutingFilter | serviceId 请求转发 | |
|
||||||
| route | 100 | SimpleHostRoutingFilter | url 请求转发 | |
|
||||||
| route | 500 | SendForwardFilter | forward 请求转发 | |
|
||||||
| post | 0 | SendErrorFilter | 处理有错误的请求响应 | |
|
||||||
| post | 1000 | SendResponseFilter | 处理正常的请求响应 | |
|
||||||
|
|
||||||
顺序值小的优先执行，`-3`之前是sop自带的过滤器，`-3`开始是zuul自带的过滤器。 |
|
||||||
|
|
||||||
创建自定义过滤器可以从`-500`开始（-1000 ~ -501留给SOP）。下面是一个自定义过虑器的例子： |
|
||||||
|
|
||||||
```java |
|
||||||
public class PreXXXFilter extends BaseZuulFilter { |
|
||||||
@Override |
|
||||||
protected FilterType getFilterType() { |
|
||||||
return FilterType.PRE; |
|
||||||
} |
|
||||||
|
|
||||||
@Override |
|
||||||
protected int getFilterOrder() { |
|
||||||
return -500; |
|
||||||
} |
|
||||||
|
|
||||||
@Override |
|
||||||
protected Object doRun(RequestContext requestContext) throws ZuulException { |
|
||||||
HttpServletRequest request = requestContext.getRequest(); |
|
||||||
ApiParam apiParam = ZuulContext.getApiParam(); |
|
||||||
String appKey = apiParam.fetchAppKey(); |
|
||||||
// ...业务处理 |
|
||||||
|
|
||||||
// 固定返回null |
|
||||||
return null; |
|
||||||
} |
|
||||||
} |
|
||||||
``` |
|
||||||
|
|
||||||
过滤器编写完毕后，在Config中使用： |
|
||||||
|
|
||||||
```java |
|
||||||
@Configuration |
|
||||||
public class ZuulConfig extends AlipayZuulConfiguration { |
|
||||||
|
|
||||||
... |
|
||||||
|
|
||||||
@Bean |
|
||||||
PreXXXFilter preXXXFilter() { |
|
||||||
return new PreXXXFilter(); |
|
||||||
} |
|
||||||
... |
|
||||||
|
|
||||||
} |
|
||||||
``` |
|
||||||
|
|
||||||
## spring cloud gateway |
|
||||||
|
|
||||||
跟zuul同理 |
|
||||||
|
|
||||||
```java |
```java |
||||||
public class XXXFilter implements GlobalFilter, Ordered { |
public class CustomFilter implements GlobalFilter, Ordered { |
||||||
|
|
||||||
@Override |
@Override |
||||||
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) { |
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) { |
||||||
ApiParam apiParam = (ApiParam)exchange.getAttribute(SopConstants.CACHE_API_PARAM); |
// 演示在网关追加header |
||||||
String appKey = apiParam.fetchAppKey(); |
ApiParam apiParam = ServerWebExchangeUtil.getApiParam(exchange); |
||||||
// ...业务处理 |
String token = apiParam.fetchAccessToken(); |
||||||
... |
ServerWebExchange serverWebExchange = ServerWebExchangeUtil.addHeaders(exchange, httpHeaders -> { |
||||||
return chain.filter(exchange); |
httpHeaders.add("token", token); |
||||||
|
}); |
||||||
|
return chain.filter(serverWebExchange); |
||||||
} |
} |
||||||
|
|
||||||
@Override |
@Override |
||||||
public int getOrder() { |
public int getOrder() { |
||||||
return -500; |
// 自定义过滤器可以从0开始 |
||||||
|
return 0; |
||||||
} |
} |
||||||
} |
} |
||||||
``` |
``` |
||||||
|
|
||||||
使用过滤器： |
使用过滤器，在sop-gateway中找到MyConfig，添加： |
||||||
|
|
||||||
```java |
```java |
||||||
@Configuration |
@Configuration |
||||||
public class GatewayConfig extends AlipayGatewayConfiguration { |
public class MyConfig { |
||||||
|
|
||||||
... |
... |
||||||
@Bean |
@Bean |
||||||
XXXFilter xxxFilter() { |
CustomFilter customFilter() { |
||||||
return new XXXFilter(); |
return new CustomFilter(); |
||||||
} |
} |
||||||
... |
... |
||||||
} |
} |
||||||
|
|||||||
