【问题描述】：

我正在尝试遵循How to use GitHub Actions build matrix to deploy artifacts to multiple servers 教程。我已经完成了一半的教程，但是在构建应用程序时出现以下错误。

Error when evaluating 'strategy' for job 'prepare-release-on-servers'. (Line: 53, Col: 17): Error reading JToken from JsonReader. Path '', line 0, position 0.,(Line: 53, Col: 17): Unexpected value ''

我已经检查了 validation 的 JSON 文件，并且无数次地检查了部署文件。

这是 deploy-application.yml 文件。

name: Deploy Application

on:
  push:
    branches:
      - main

jobs:
  create-deployment-artifacts:
    name: Create deployment artifacts
    runs-on: ubuntu-latest
    outputs:
      deployment-matrix: $ steps.export-deployment-matrix.outputs.deployment-matrix 

    steps:
      - uses: actions/checkout@v2
      - name: Compile CSS and javascript
        run: |
          npm install
          npm run prod

      - name: Configure php 8.0
        uses: shivammathur/setup-php@v2
        with:
          php-version: 8.0
          extensions: mbstring, ctype, fileinfo, openssl, PDO, bcmath, json, tokenizer, xml
      - name: composer install
        run: |
          composer install --no-dev --no-interaction --prefer-dist
      - name: Create deployment artifact
        env:
          GITHUB_SHA: $ github.sha 
        run: tar -czf "$GITHUB_SHA".tar.gz --exclude=*.git --exclude=node_modules --exclude=tests *
      - name: Store artifact for distribution
        uses: actions/upload-artifact@v2
        with:
          name: app-build
          path: $ github.sha .tar.gz
      - name: Export deployment matrix
        id: export-deployment-matrix
        run: |
          JSON="$(cat ./deployment-config.json)"
          JSON="$JSON//'%'/'%25'"
          JSON="$JSON//$'\n'/'%0A'"
          JSON="$JSON//$'\r'/'%0D'"
          echo "::set-output name=deployment-matrix::$(echo $JSON)"
  prepare-release-on-servers:
    name: "$ matrix.server.name : Prepare release"
    runs-on: ubuntu-latest
    needs: create-deployment-artifacts
    strategy:
      matrix:
        server: $ fromJson(needs.create-deployment-artifacts.outputs.deployment-matrix) 
    steps:
      - uses: actions/download-artifact@v2
        with:
          name: app-build

这是 JSON 文件。

["name":"server-1","ip":"216.656.30.240","username":"root","password":"sdddssafilgwzxcxvgvggfdassa","port":"22","beforeHooks":"","afterHooks": "","path": "/var/www/html" ]

我在这里找不到问题。你能帮忙的话，我会很高兴。提前致谢。

【参考方案1】：

当set-output应该被fromJSON加载时，所有双引号"应该被替换（转义）到$JSON字符串中的\"。见this post。
