nacos-client 1.4.1可以正常注册。

debug info:

when

rpcClient.request(request)

request header accessToken was gone。

已解决此问题：我的nacos自建账号没有分配public命名空间权限，在nacos-client 1.4.1上可以正常使用。升级nacos-client2.0后无法注册，分配public命名空间权限后，已可以正常注册。

jackwang-wangcb commented 3 years ago

想问下那个端口 - "9555:9555" 是干啥用的？

warthur1214 commented 3 years ago

@jackwang-wangcb 我没关注，是按官方部署文档下载的yaml。 https://github.com/nacos-group/nacos-docker.git

KomachiSion commented 3 years ago

返回码403，说明打开了鉴权但是没有输入用户名密码，所以鉴权失败导致了注册失败。或者是用户名密码错误

KomachiSion commented 3 years ago

可以试着debug一下，getSecurityHeader 方法，看下里面的用户名密码是不是正确的

@KomachiSion 在 rpcClient.request(request) 之前鉴权token是存在的，我用nacos-client 1.4.1客户端是可以正常注册。debug信息如下：

KomachiSion commented 3 years ago

我复现不出来这个问题。我试了下发起请求前request里是有token的，返回后可能被grpcCLient回收了，但是确实是可以注册的

KomachiSion commented 3 years ago

然后我故意把密码改错，得到了403的返回。我认为应该还是设置有问题吧。

或者你提供下你的赋权等信息。

warthur1214 commented 3 years ago

@KomachiSion 没法复现，确实不好定位问题来源。主要是我配置信息都不变，把nacos-client版本改成1.4.1可以正常注册我的bootstrap.yaml文件如下：

spring:
  application:
    name: spring-cloud-nacos-demo
  main:
    allow-bean-definition-overriding: true
  cloud:
    nacos:
      username: nacos
      password: nacos
      discovery:
        server-addr: localhost:8848
        group: DEFAULT_GROUP
      config:
        server-addr: ${spring.cloud.nacos.discovery.server-addr}
        file-extension: yaml
        namespace: ${spring.cloud.nacos.discovery.namespace}
        extension-configs:
          - refresh: true
            dataId: redis.yaml
          - refresh: true
            dataId: jdbc.yaml
          - refresh: true
            dataId: logback.yaml
          - refresh: true
            dataId: mybatis.yaml
        group: ${spring.cloud.nacos.discovery.group}

调试信息截图：

warthur1214 commented 3 years ago

@KomachiSion 我用的是自建账号密码，当我改成nacos账号后可以注册了。可能是我的账号权限问题，奇怪的是在客户端1.4.1上没有遇到这个问题。我再研究下，感谢你抽时间帮我排查问题。
