如何使用Google Script（非Google Script API）在Google幻灯片中替换文本为图片

Let’s walk through two approaches to achieve this—one using the Advanced Slides Service (your initial code, adjusted for clarity) and a native SlidesApp method if you prefer avoiding advanced services.

Option 1: Fixing Your Advanced Service Code #

Your code uses the Advanced Slides Service (a built-in part of Google Apps Script, not the external REST API). To get it working, first enable the service:

1. Open your Apps Script project.
2. Go to Services > Add Service.
3. Select Google Slides API and click Add.

Here’s your code with explanatory comments:

function insertImageCentered() { 
  var presentation = SlidesApp.getActivePresentation(); 
  var requests = [{ 
    "replaceAllShapesWithImage": { 
      "imageUrl": "https://docs.google.com/drawings/d/e/2PACX-1vR5mi6ujksb_2WtTFmk39IPYBIBlJ6WkzM1nsys9cT4Wquik627DDIRXzoYTgHPKX3fcvJzG9inDmJt/pub?w=960&h=720", 
      "imageReplaceMethod": "CENTER_INSIDE", // Centers image within the original shape's bounds
      "pageObjectIds": [presentation.getSlides()[0].getObjectId()], // Target only the first slide
      "containsText": { 
        "text": "{{CENTERED_SHAPE}}", // Text string to match and replace
        "matchCase": false // Ignore uppercase/lowercase differences
      } 
    } 
  }]; 
  // Send the batch update to replace all matching shapes
  Slides.Presentations.batchUpdate({'requests': requests}, presentation.getId()); 
}

This method is efficient for bulk replacements across slides, as it uses a single API call to handle all matches.

Option 2: Native SlidesApp Method (No Advanced Service) #

If you want to avoid enabling the Advanced Slides Service, you can manually iterate through shapes and replace them with images. This gives you more control over individual elements:

function replaceTextWithImageNative() {
  var presentation = SlidesApp.getActivePresentation();
  var targetSlide = presentation.getSlides()[0]; // Focus on the first slide
  var targetText = "{{CENTERED_SHAPE}}";
  var imageUrl = "https://docs.google.com/drawings/d/e/2PACX-1vR5mi6ujksb_2WtTFmk39IPYBIBlJ6WkzM1nsys9cT4Wquik627DDIRXzoYTgHPKX3fcvJzG9inDmJt/pub?w=960&h=720";
  
  // Get all shapes on the target slide
  var shapes = targetSlide.getShapes();
  
  // Loop backwards to avoid index issues when deleting shapes
  for (var i = shapes.length - 1; i >= 0; i--) {
    var shape = shapes[i];
    var shapeText = shape.getText().asString().trim();
    
    // Check if the shape contains the exact target text
    if (shapeText === targetText) {
      // Capture the shape's position and size
      var left = shape.getLeft();
      var top = shape.getTop();
      var width = shape.getWidth();
      var height = shape.getHeight();
      
      // Insert the image at the same location and dimensions
      targetSlide.insertImage(imageUrl, left, top, width, height);
      
      // Remove the original text shape
      shape.remove();
    }
  }
}

Key Notes: #

• Ensure your image URL is publicly accessible (your Google Drawing link works since it’s published).
• Test both methods on a copy of your presentation first to avoid accidental changes.
• The Advanced Service method is faster for large presentations, while the native method is better for custom logic (e.g., replacing only specific instances).
