request help: upstreamNode json解析异常

[marchlhw]

Issue description

问题1：

1. admin api根据id获取upstream json数据如下：

2. apisix-ingress-controller定义的数据结构如下：

3. 注释红框中的判断，否则解析报错

3.1 不注释代码的情况下，报错：

2022-08-04 22:04:55.984	error	unexpected non-empty object

3.2 注释代码的情况下，upstreamNode解析为空：

&{Metadata:{ID:419230261889204925 Name:test Desc: Labels:map[]} Type:roundrobin HashOn: Key: Checks:<nil> Nodes:[] Scheme:http Retries:<nil> Timeout:0xc0000d80d8 TLS:<nil>}

4. 下面的json数据结构不注释代码的情况下也可以正常解析

Environment

• your apisix-ingress-controller version (output of apisix-ingress-controller version --long): 1.5.0
• your Kubernetes cluster version (output of kubectl version): 1.18
• if you run apisix-ingress-controller in Bare-metal environment, also show your OS version (uname -a): centos7.4

Thank you very much. I am trying to reproduce this problem. This problem does exist.

Can you tell me the version of your apisix-dashboard？

Can you tell me the version of your apisix-dashboard？

apisix-dashboard 我用的最新的master分支，我看manager-api的源码有做数据结构转换 https://github.com/apache/apisix-dashboard/blob/master/api/internal/core/entity/format.go

@bzp2010 Could you help confirm this if you have time?

apisix-ingress-controller调用的是admin-api，会有上面提到的数据解析问题；manager-api虽然有对upstreamNodes做数据结构转换，响应的json数据controller可以正常的解析，但是controller只支持api-key的验证，而manager-api是jwt的验证

I'll fix it #1222 .
