使用Helm部署Pact Broker失败：仓库无效或无法访问求助

按照Pact Broker Kubernetes官方文档操作时，添加helm仓库遇到报错：

C:\temp\helm-v3.11.1-windows-amd64\windows-amd64>helm repo add bitnami https://charts.bitnami.com/bitnami
"bitnami" has been added to your repositories

C:\temp\helm-v3.11.1-windows-amd64\windows-amd64>helm repo add pact-broker https://pact-foundation.github.io/pact-broker-chart/
Error: looks like "https://pact-foundation.github.io/pact-broker-chart/" is not a valid chart repository or cannot be reached: Get "https://pact-foundation.github.io/pact-broker-chart/index.yaml": dial tcp 185.199.110.153:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

已确认网络、代理正常（添加bitnami仓库成功），能直接打开报错中的index.yaml文件，但访问不带.yaml的URL返回404，怀疑官方文档存在问题。

• 先清掉helm本地缓存，重新尝试添加仓库：

  helm repo remove pact-broker
  helm repo update
  helm repo add pact-broker https://pact-foundation.github.io/pact-broker-chart/
  

• 如果还是不行，直接用index.yaml的完整URL作为仓库地址（有些环境下helm对仓库根路径的解析有问题）：

  helm repo add pact-broker https://pact-foundation.github.io/pact-broker-chart/index.yaml
  

• 刷新本地DNS缓存（Windows下执行ipconfig /flushdns），排除DNS解析异常导致的连接超时。
• 要是确定是文档的问题，直接下载官方chart包本地安装：

  # 下载最新chart包
  wget https://github.com/pact-foundation/pact-broker-chart/releases/latest/download/pact-broker.tgz -OutFile pact-broker.tgz
  # 本地安装
  helm install pact-broker ./pact-broker.tgz
