Question

我有一个使用Google Apps脚本构建的网络应用，它使用外部API服务将html网页转换为整洁的PDF文件，并将其下载到用户的本地计算机上 - 没有任何问题。

现在我需要接受该响应（PDF文件）并使用驱动器文件夹ID将其上传到Drive上的特定文件夹。

我的问题是尝试捕获该API响应对象。我在一个单独的Web应用程序中使用不同的html-to-pdf API完成了这项工作，因此我知道我的大部分代码都是合理的。但我没有正确捕捉那个物体。也许有一种Google Apps脚本方法可以让这更容易，但我无法弄明白。

奇怪的是，在Google Apps脚本中运行Drive API的文档是不存在的。

请为gawd的爱，帮助编码器！

所以不要从你的Javascript（客户端）调用你的Api，而是使用UrlFetch在服务器端这样做

f:validateRegex

然后，您可以使用function convert(html) { var urltoconvert = "https://pdflayer.com/documentation"; var authkey = "XXXXXX"; var url = "http://api.pdflayer.com/api/convert" + "?access_key=" + authkey + "&document_name=Purchase_Order.pdf" + "&page_size=A4" + "&css_url=https://s3-us-west-2.amazonaws.com/www.fortlauderdaletech.org/postyles.css"; var payload = { "document_html": html } var options = { "method" : "POST", payload : payload } var response = UrlFetchApp.getRequest(url,options) doSomethingForTheLoveOfGawd(response) return JSON.stringify(response) }功能

处理对云端硬盘文件的回复

要在客户端下载文件，请将响应传递回客户端并使用doSomethingForTheLoveOfGawd处理返回的数据

注意我不确定API的响应结构，所以这是通用代码。根据需要修改

.withSuccessHandler

捕获API响应并将其上传到云端硬盘
