Google Apps 脚本 - 使用文本按钮和网址时出错

Question

我在为 gmail 开发的附加组件上遇到问题，我需要创建一个文本按钮，单击该按钮后，用户可以转到某个 URL。但是当用户单击它时，控制台上会显示以下消息：

Refused to run the JavaScript URL because it violates the following Content Security Policy directive: "script-src 'report-sample' 'nonce-meBQMySza2c9vxRO9k5EAQ' 'unsafe-inline'". Note that 'unsafe-inline' is ignored if either a hash or nonce value is present in the source list.

Refused to run the JavaScript URL because it violates the following Content Security Policy directive: "script-src 'nonce-meBQMySza2c9vxRO9k5EAQ' 'self' https://apis.google.com https://ssl.gstatic.com https://www.google.com https://www.gstatic.com https://www.google-analytics.com". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution. Note that hashes do not apply to event handlers, style attributes and javascript: navigations unless the 'unsafe-hashes' keyword is present.

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'location')

我尝试过这两种解决方案：

解决方案 1 - 使用 setOpenLink

  function getLink(link) {
    return CardService.newTextButton()
             .setText("Go to URL")
             .setOpenLink(CardService.newOpenLink()
             .setUrl(link));
  }

解决方案 2 - 使用 setOnClickOpenLinkAction

  function openLinkCallback(state) {    
    return CardService.newActionResponseBuilder()
             .setOpenLink(CardService.newOpenLink()
             .setUrl(state.parameters.link))
             .build();
  }

  function getLink(link) {
    var action = CardService.newAction().setFunctionName('openLinkCallback').setParameters({ link: link });

    return CardService.newTextButton()
             .setText("Go to URL")
             .setOnClickOpenLinkAction(action)
  }

哪一种是向用户显示链接的正确方式？还有一件事我可能忘记在这里实现吗？

我的 appsscript.json 文件是：

{
  "timeZone": "America/Denver",
  "dependencies": {},
  "addOns": {
    "common": {
      "homepageTrigger": {
        "runFunction": "handleHomePageStart",

          }
        ],
        "draftAccess": "METADATA"
      }
    },
    "calendar": {}
  },

  ]
}

提前致谢！

更新：似乎这个问题无法在 Firefox 上重现，只能在 Chrome 上重现......

Answer 1

在您的问题中，您没有确切指定要尝试打开的链接，但请确保其网址前缀包含在 appsscript.json 中的“openLinkUrlPrefixes”中。

因此，如果您想打开“https://leprosy.com/a”，您应该将“https://leprosy.com”添加到“openLinkUrlPrefixes”中。可能有帮助。
