## 微服务端如何获取appId等参数

## 如何关闭签名验证
|
||||
|
||||
- 针对某一个接口关闭签名验证
|
||||
`@Open(value = "alipay.story.get", ignoreValidate = true)`
|
||||
|
||||
- 针对所有接口关闭签名验证
|
||||
|
||||
```java
|
||||
@Configuration
|
||||
public class ZuulConfig extends AlipayZuulConfiguration {
|
||||
|
||||
static {

## 指定了context-path(拉取路由404)
|
||||
|
||||
微服务项目定义了`server.servlet.context-path=/story-service`,同时必须指定:
|
||||
|
||||
```properties
|
||||
spring.cloud.nacos.discovery.metadata.context-path=${server.servlet.context-path}
|
||||
```
|
||||
|
||||
yml配置如下:
|
||||
|
||||
```yaml
|
||||
spring:
|
||||
cloud:
|
||||
nacos:
|
||||
discovery:
|
||||
metadata:
|
||||
context-path: ${server.servlet.context-path}
|
||||
```
|

不然网关无法拉取路由信息

## 其它微服务没有开放接口,需要排除
