GitHub Actions报错：Unrecognized named-value: 'github' 求助

核心问题 #

可复用工作流（被其他工作流调用的）不能通过github.events.inputs获取调用方传递的参数，正确的引用方式是直接使用inputs.xxx，同时必须在工作流的on: workflow_call中显式定义输入参数（仅workflow_dispatch无法支持跨工作流调用的参数传递）。

具体修改步骤 #

1. 更新工作流触发配置，添加workflow_call并定义输入参数
   在on字段中同时保留workflow_dispatch（支持手动触发）和workflow_call（支持被其他工作流调用），两者的输入参数定义保持一致：

   on:
     workflow_dispatch:
       inputs:
         context:
           description: The context used for the "docker build" command.
           required: true
         dockerfile:
           description: The dockerfile used for the "docker build" command.
           required: true
         image_name:
           description: The name of the image to publish
           required: true
         registry:
           description: The registry where the image will be uploaded.
           required: true
         registry-user:
           description: The username used for the login.
           required: true
         registry-password:
           description: The password used for the login to the registry.
           required: true
     workflow_call:
       inputs:
         context:
           description: The context used for the "docker build" command.
           required: true
           type: string
         dockerfile:
           description: The dockerfile used for the "docker build" command.
           required: true
           type: string
         image_name:
           description: The name of the image to publish
           required: true
           type: string
         registry:
           description: The registry where the image will be uploaded.
           required: true
           type: string
         registry-user:
           description: The username used for the login.
           required: true
           type: string
         registry-password:
           description: The password used for the login to the registry.
           required: true
           type: string
   

2. 替换所有参数引用为inputs.xxx
   将代码中所有github.events.inputs.xxx替换为inputs.xxx，例如：

   • 原context: ${{ github.events.inputs.context }}改为context: ${{ inputs.context }}
   • 原tags: ${{ github.events.inputs.image_name }}:${{ github.sha }}改为tags: ${{ inputs.image_name }}:${{ github.sha }}

3. 处理发布标签的上下文（可选）
   如果需要在可复用工作流中获取调用方的release标签，github.event.release.tag_name仅在调用方的工作流由release事件触发时可用，无需修改（该上下文属于触发调用方工作流的事件，可正常访问）。

调用方式无需修改 #

你原来的调用代码保持不变即可，调用方通过with传递的参数会自动映射到可复用工作流的inputs对象中。
