我正在实现通过 POST 向外部 API 发出请求的 Office JS 自定义函数。目前，我在桌面上使用自定义函数运行时收到错误“网络错误”。

此错误仅在发送数据时发生（带有 axios 的数据配置选项）。发送时，data: undefined我收到一个成功的发布请求。Fetch/XMLHttp 给出同样的错误。这些发布请求在 excel Web 客户端上运行良好。

有问题的代码很简单：

    return axios.post('api endpoint', {...data})
        .then(response =>{ 
            console.log(response)
        });

函数.html

    <script src="https://appsforoffice.microsoft.com/lib/1.1/hosted/custom-functions-runtime.js" type="text/javascript"></script>

错误：

这可能是因为自定义函数尚不支持完整的 CORS。团队正在努力，应该很快就会在这里更新：
