## 如何关闭签名验证
|
|
|
|
- 针对某一个接口关闭签名验证
|
|
`@ApiMapping(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 {
|
|
...
|
|
ApiConfig.getInstance().setIgnoreValidate(true);
|
|
...
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
## 注册到eureka显示hostname，非ip
|
|
|
|
```yaml
|
|
eureka:
|
|
instance:
|
|
prefer-ip-address: true
|
|
instance-id: ${spring.cloud.client.ip-address}:${server.port}
|
|
```
|
|
|
|
```xml
|
|
<dependency>
|
|
<groupId>org.springframework.cloud</groupId>
|
|
<artifactId>spring-cloud-commons</artifactId>
|
|
</dependency>
|
|
```

## 直接访问服务的swagger-ui.html ，提示access forbidden
|
|
|
|
找到微服务的`OpenServiceConfig.java`，重写内部类Swagger2中的swaggerAccessProtected()方法，返回false。线上请设置成true
|
|
|
|
```java
|
|
// 开启文档
|
|
@Configuration
|
|
@EnableSwagger2
|
|
public static class Swagger2 extends SwaggerSupport {
|
|
@Override
|
|
protected String getDocTitle() {
|
|
return "故事API";
|
|
}
|
|
|
|
@Override
|
|
protected boolean swaggerAccessProtected() {
|
|
return false;
|
|
}
|
|
}
|
|
```

## 调试网关出现服务不可用
|
|
|
|
打断点调试，网关出现Read Timeout
|
|
|
|
参考：https://blog.csdn.net/qq_36872046/article/details/81058045
|
|
|
|
yml添加：
|
|
|
|
```yaml
|
|
ribbon:
|
|
# https://blog.csdn.net/qq_36872046/article/details/81058045
|
|
# 路由转发超时时间，毫秒，默认值1000，详见：RibbonClientConfiguration.DEFAULT_READ_TIMEOUT。
|
|
# 如果微服务端 处理时间过长，会导致ribbon read超时，解决办法将这个值调大一点
|
|
ReadTimeout: 60000
|
|
``` |
