从Apps脚本中的URL调用图像 [英] call an image from URL in Apps Script

问题描述

我编写了一个调用Google文档的程序，该文档中有一个名为#Name#的变量，该变量被存储在SpreadSheet中的名称代替.

I programmed one that calls a Google Doc and in said Doc there is a variable called #Name# this is replaced by the name that is stored in a SpreadSheet.

我的问题是，我想向该文档添加一个名为#Photo#的变量，并将其替换为存储在Drive URL中的照片，并且此URL位于SpreadSheet中.

My question is that to that Doc I want to add a variable called # Photo # and it is replaced by the photo stored in a Drive URL and this URL is in a SpreadSheet

如何调用电子表格中的URL，并能够替换字段#photo#

How can I call that URL that is in Spreadsheet and be able to replace the field #photo#

名称与该功能配合得很好

With the name it does well with the function

body.replaceText('#name#'，名称);

但是有了图片，我不知道该怎么称呼

but with the image I don't know what to call it

推荐答案

由于 #Photo#是其自身的一个段落，因此您可以执行以下操作:

Since #Photo# is a paragraph of its own, you can do the following:

• 使用文档正文，找到文本通过 findText(searchPattern) #Photo#并通过 getElement().
• 检索到此元素后，可以删除文本( #Photo#)，因为即使文本为空字符串，元素本身也将存在.您可以为此使用 setText(")
• 通过 UrlFetchApp.fetch(url)和 getBlob().
• 获取检索到的元素的父级，该父级是 #Photo#的一部分，并使用

• Using the Document Body, find the text #Photo# via findText(searchPattern) and get the Element that corresponds to this text via getElement().
• Once you have retrieved this element, you can remove the text (#Photo#), since the element itself will exist even if the text is an empty string. You can use setText("") for that.
• Get the Blob from the image URL via UrlFetchApp.fetch(url) and getBlob().
• Get the retrieved element's parent, which is the paragraph #Photo# was part of, and use insertInlineImage to insert the retrieved image to the beginning of this paragraph.

function replaceTextWithImage() {
  var body = DocumentApp.getActiveDocument().getBody(); // Get current document's body
  var element = body.findText("#Photo#").getElement(); // Get element of #Photo#
  element.asText().setText(""); // Remove #Photo# placeholder
  var url = "YOUR_IMAGE_URL"; // Change this accordingly
  var blob = UrlFetchApp.fetch(url).getBlob(); // Get blob from image URL
  var image = element.getParent().asParagraph().insertInlineImage(0, blob); // Insert image
}

注意:

• 我假设您的问题只是关于将图像插入到文档中，而不是关于填充电子表格，检索图像URL等之前的步骤.
• 此示例引用了绑定到Google文档的脚本(因此，该脚本使用的是 openById(id)或 openByUrl(url).

Notes:

• I'm assuming that your question was only about inserting the image to the Document, not about the previous steps of populating the spreadsheet, retrieving the image URL, etc.
• This sample refers to a script that is bound to the Google Doc (hence, it's using getActiveDocument() to retrieve the Doc). If that's not the case, you should retrieve the document via openById(id) or openByUrl(url).
