如何通过AppScript实现Google幻灯片中文字的“形状适配文字”调整？

尝试调整Google Slides中已渲染文字的自动适配效果，调用自定义的updateTextAutoFit函数时触发API错误：

Failed with error API call to slides.presentations.batchUpdate failed with error: Invalid requests[0].updateShapeProperties: The object (SLIDES_API1782835896_0) could not be found.

附相关代码：

function updateTextAutoFit(presentationId: string, objectId: string) {
  const requests: GoogleAppsScript.Slides.Schema.Request[] = [
    {
      updateShapeProperties: {
        objectId: objectId,
        fields: "autofit",
        shapeProperties: {
          // @ts-ignore
          autofit: {
            autofitType: "SHAPE_AUTOFIT",
          },
        },
      },
    },
  ];
  try {
    const slide = Slides.Presentations?.batchUpdate(
      { requests: requests },
      presentationId
    );
    return slide;
  } catch (e: any) {
    Logger.log("Failed with error %s", e.message);
  }
}

const titleText = createTextBox({
  slide,
  text: title,
  fontSize: 28,
  isBold: true,
  position: titlePosition,
  presentationId,
});

updateTextAutoFit(presentationId, id); 

1. 修正变量传递错误 #

你调用updateTextAutoFit时传入的id并非刚创建的文本框对象ID，应该使用createTextBox返回的titleText中的对象ID：

// 替换原调用代码
updateTextAutoFit(presentationId, titleText.objectId);

注意：确保createTextBox函数正确返回包含objectId的对象（通常创建形状后，Slides API会自动生成并返回该ID）。

2. 验证自动适配类型 #

根据需求确认autofitType的取值：

• SHAPE_AUTOFIT: 调整形状大小以适配文本
• TEXT_AUTOFIT: 调整文本字号以适配形状
• NONE: 关闭自动适配

3. 可选：创建文本框时直接设置自动适配 #

如果不需要单独调用函数，也可以在创建文本框的请求中直接添加自动适配配置，避免后续调用出错：

// 示例：在createTextBox内部的batchUpdate请求中加入autofit设置
function createTextBox(options) {
  const customObjectId = "TEXT_BOX_" + Date.now(); // 生成唯一ID
  const requests = [
    {
      createShape: {
        objectId: customObjectId,
        shapeType: "TEXT_BOX",
        elementProperties: {
          pageObjectId: options.slide.objectId,
          size: { width: { magnitude: 500, unit: "PT" }, height: { magnitude: 100, unit: "PT" } },
          transform: { scaleX: 1, scaleY: 1, translateX: options.position.x, translateY: options.position.y, unit: "PT" }
        }
      }
    },
    {
      insertText: {
        objectId: customObjectId,
        text: options.text
      }
    },
    {
      updateShapeProperties: {
        objectId: customObjectId,
        fields: "autofit",
        shapeProperties: {
          autofit: {
            autofitType: "SHAPE_AUTOFIT"
          }
        }
      }
    },
    {
      updateTextStyle: {
        objectId: customObjectId,
        textRange: { type: "ALL" },
        style: {
          fontSize: { magnitude: options.fontSize, unit: "PT" },
          bold: options.isBold
        },
        fields: "fontSize,bold"
      }
    }
  ];
  
  const response = Slides.Presentations.batchUpdate({ requests }, options.presentationId);
  return { objectId: response.replies[0].createShape.objectId };
}
