Question

我对YAML语法不太熟悉，在验证我的bitbucket-pipelines.yaml文件时遇到了一些麻烦。

我从在线YAML解析器中获得以下内容：

ERROR:

while scanning for the next token
found character '%' that cannot start any token
  in "<unicode string>", line 18, column 234:
     ... CKET_BRANCH, \"Date\": $(date +"%m-%d-%y"), \

语法有什么问题？如何更正此错误？

pipelines:
  branches:
    master:
      - step:
          script:
            - echo "Runing pip-lee-nes for ARGUS"
            - echo "Deploy to live"
            - export AWS_ACCESS_KEY_ID=$LIVE_AWS_ACCESS_KEY_ID
            - export AWS_SECRET_ACCESS_KEY=$LIVE_AWS_SECRET_ACCESS_KEY
            - export AWS_DEFAULT_REGION=$LIVE_AWS_REGION
            - node -v
            - npm --version
            - npm run config $LIVE_BUCKET_NAME $LIVE_AWS_REGION
            - npm run setup
            - "aws sns publish --topic-arn arn:aws:sns:$LIVe_REGION:$LIVE_AWS_ACCOUNT_ID:new_release --subject \"$BITBUCKET_REPO_SLUG\" --message \"{\"Commit\": $BITBUCKET_COMMIT, \"Branch\": $BITBUCKET_BRANCH, \"Date\": $(date +"%m-%d-%y"), \"Time\": $(date +"%T")}\"

    develop:
      - step:
          script:
            - echo "Runing pip-lee-nes for ARGUS"
            - echo "Deploy to staging"
            - export AWS_ACCESS_KEY_ID=$STAGING_AWS_ACCESS_KEY_ID
            - export AWS_SECRET_ACCESS_KEY=$STAGING_AWS_SECRET_ACCESS_KEY
            - export AWS_DEFAULT_REGION=$DEFAULT_REGION
            - node -v
            - npm --version
            - npm run config $STAGING_BUCKET_NAME $DEFAULT_REGION
            - npm run setup
            - "aws sns publish --topic-arn arn:aws:sns:$DEFAULT_REGION:$STAGING_AWS_ACCOUNT_ID:new_release --subject \"$BITBUCKET_REPO_SLUG\" --message \"{\"Commit\": $BITBUCKET_COMMIT, \"Branch\": $BITBUCKET_BRANCH, \"Date\": $(date +"%m-%d-%y"), \"Time\": "$(date +"%T")}\"

如果你稍微缩短有问题的标量：

"aws ... \"Branch\": $BITBUCKET_BRANCH, \"Date\": $(date +"%m-%d-%y"), \"Time\": $(date +"%T")}\"

您可以看到它以双引号开头，以\之后的第一个未转义（即无: $(date +）双引号结束。解析器读取的下一个标记，以%开头来自%m-%d-%y并且不允许这样做。你可能想这样做：

"aws ... \"Branch\": $BITBUCKET_BRANCH, \"Date\": $(date +\"%m-%d-%y\"), \"Time\": $(date +\"%T\")}"

（请注意，我插入了4个反斜杠和删除了尾部双引号的反斜杠）。这样你就得到一个有效的双引号YAML标量。

由于你只是转义双引号并且你的字符串中没有单引号，你可能最好使用整个单引号并删除反斜杠：

- 'aws sns publish --topic-arn arn:aws:sns:$LIVe_REGION:$LIVE_AWS_ACCOUNT_ID:new_release --subject "$BITBUCKET_REPO_SLUG" --message "{"Commit": $BITBUCKET_COMMIT, "Branch": $BITBUCKET_BRANCH, "Date": $(date +"%m-%d-%y"), "Time": $(date +"%T")}'
