常见问题
在zuul过滤器中获取请求参数
ApiParam param = ZuulContext.getApiParam();
在SpringCloudGateway中获取请求参数
ApiParam apiParam = ServerWebExchangeUtil.getApiParam(exchange);
微服务端如何获取appId等参数
OpenContext openContext = ServiceContext.getCurrentContext().getOpenContext();
String appId = openContext.getAppId();
在其它地方获取业务参数
OpenContext openContext = ServiceContext.getCurrentContext().getOpenContext();
Story bizObject = (Story)openContext.getBizObject();
或
OpenContext openContext = ServiceContext.getCurrentContext().getOpenContext();
Story bizObject = openContext.getBizObject(Story.class);
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
@Configuration
public class ZuulConfig extends AlipayZuulConfiguration {
static {
...
ApiConfig.getInstance().setIgnoreValidate(true);
...
}
}
注册到eureka显示hostname,非ip
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=${spring.cloud.client.ip-address}:${server.port}

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
// 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:
# 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
ribbon.ReadTimeout: 60000
指定了context-path
微服务项目定义了server.servlet.context-path=/story-service
,同时必须指定:
spring.cloud.nacos.discovery.metadata.server.servlet.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
在sop-gateway项目中配置
# 排除服务,多个用,隔开
sop.service.exclude=your-serviceId1,your-serviceId2
或者使用正则:
# 排除以"test-"开头的
# 多个正则用英文分号(;)隔开
sop.service.exclude-regex=test\\-.*
