Python调用Adobe InDesign 2024+ JSX脚本报错求助

尝试通过Python调用Adobe InDesign 2024或更高版本执行JSX脚本，参考旧版本示例代码编写测试脚本后，运行报错。

原测试代码：

import win32com.client

def create_indesign_document_with_text():
    try:
        # Initialize COM
        print("Initializing COM...")
        app = win32com.client.Dispatch('InDesign.Application')

        # Create a new InDesign document
        print("Creating a new InDesign document...")
        doc = app.Documents.Add()

        # Define the text content
        text_content = ("This is a sample text with some bold and italic words. "
                        "The quick brown fox jumps over the lazy dog. " * 5)
        # Define text attributes
        bold_text = "This is bold text."
        italic_text = "This is italic text."

        # Create a text frame
        print("Adding a text frame with sample content...")
        page = doc.Pages.Item(1)
        text_frame = page.TextFrames.Add()
        text_frame.GeometricBounds = ["12.7mm", "12.7mm", "287mm", "200mm"]  # Adjust the bounds as needed

        # Add the main text content
        text_frame.Contents = text_content

        # Apply formatting to parts of the text
        # Note: InDesign uses 0-based index for characters
        text_range = text_frame.Characters
        text_range.Item(0).ChangeTextPreferences.appliedFont = app.Fonts.Item("Arial")
        text_range.Item(0).ChangeTextPreferences.fontStyle = "Bold"
        text_range.Item(0).ChangeTextPreferences.pointSize = 12

        # Apply bold formatting to a specific range
        bold_start = text_content.find(bold_text)
        bold_end = bold_start + len(bold_text)
        text_range.ItemByRange(bold_start, bold_end - 1).ChangeTextPreferences.fontStyle = "Bold"

        # Apply italic formatting to a specific range
        italic_start = text_content.find(italic_text)
        italic_end = italic_start + len(italic_text)
        text_range.ItemByRange(italic_start, italic_end - 1).ChangeTextPreferences.fontStyle = "Italic"

        # Save the InDesign document
        save_path = r'INDESIGN_FILE_PATH'
        print(f"Saving the InDesign document to {save_path}...")
        doc.Save(save_path)

        # Call the JSX script
        jsx_script_path = r'JSX_FILE_PATH'
        print(f"Executing JSX script: {jsx_script_path}...")
        app.DoScript(jsx_script_path, 1246973031)  # Use ScriptLanguage.JAVASCRIPT

        print("Document created and script executed successfully.")

        # Close the document
        print("Closing the InDesign document without saving changes...")
        doc.Close(1)  # 1 means save changes

    except Exception as e:
        print(f"An error occurred: {e}")

if __name__ == "__main__":
    create_indesign_document_with_text()

运行错误信息：

Initializing COM...
Creating a new InDesign document...
Adding a text frame with sample content...
An error occurred: (-2147352567, 'Exception occurred.',
 (30475, 'INDESIGN EXE PATH',  'The requested member of the collection does not exist.', None, 0, 0), None)

错误根源分析 #

• 字符索引错误：InDesign的Characters集合采用1-based索引，原代码错误使用0-based（Item(0)），导致找不到对应成员。
• 目标文本缺失：定义的bold_text和italic_text并未包含在text_content中，find()返回-1，后续ItemByRange使用无效索引触发报错。
• ChangeTextPreferences用法错误：该对象用于全局文本修改偏好设置，不能直接通过单个Character对象赋值，应直接修改文本范围的属性。
• 注释与代码矛盾：doc.Close(1)表示保存后关闭，但注释标注“不保存”，逻辑混乱。

修正后的代码 #

import win32com.client

def create_indesign_document_with_text():
    try:
        # Initialize COM
        print("Initializing COM...")
        app = win32com.client.Dispatch('InDesign.Application')

        # Create a new InDesign document
        print("Creating a new InDesign document...")
        doc = app.Documents.Add()

        # 修正：在文本内容中加入需要格式化的目标文本
        bold_text = "This is bold text."
        italic_text = "This is italic text."
        text_content = (f"This is a sample text with some bold and italic words. {bold_text} "
                        f"The quick brown fox jumps over the lazy dog. {italic_text} " * 5)

        # Create a text frame
        print("Adding a text frame with sample content...")
        # InDesign Pages集合是1-based索引，Item(1)正确
        page = doc.Pages.Item(1)
        text_frame = page.TextFrames.Add()
        # 修正：GeometricBounds使用数值（InDesign默认单位为点，12.7mm≈36pt）
        text_frame.GeometricBounds = [36, 36, 814, 567]

        # Add the main text content
        text_frame.Contents = text_content

        # Apply formatting to parts of the text
        # 修正：使用1-based索引获取字符范围，直接修改文本属性
        all_chars = text_frame.Characters
        # 设置第一个字符的格式（示例）
        first_char = all_chars.Item(1)
        first_char.appliedFont = app.Fonts.Item("Arial")
        first_char.fontStyle = "Bold"
        first_char.pointSize = 12

        # Apply bold formatting to a specific range
        bold_start = text_content.find(bold_text) + 1  # 转换为1-based索引
        bold_end = bold_start + len(bold_text) - 1
        bold_range = all_chars.ItemByRange(bold_start, bold_end)
        bold_range.fontStyle = "Bold"
        bold_range.appliedFont = app.Fonts.Item("Arial")

        # Apply italic formatting to a specific range
        italic_start = text_content.find(italic_text) + 1  # 转换为1-based索引
        italic_end = italic_start + len(italic_text) - 1
        italic_range = all_chars.ItemByRange(italic_start, italic_end)
        italic_range.fontStyle = "Italic"
        italic_range.appliedFont = app.Fonts.Item("Arial")

        # Save the InDesign document
        save_path = r'C:\test_indesign_document.indd'  # 替换为实际保存路径
        print(f"Saving the InDesign document to {save_path}...")
        doc.Save(save_path)

        # Call the JSX script
        jsx_script_path = r'C:\test_script.jsx'  # 替换为实际JSX路径
        print(f"Executing JSX script: {jsx_script_path}...")
        # ScriptLanguage.JAVASCRIPT的常量值为1246973031，正确
        app.DoScript(jsx_script_path, 1246973031)

        print("Document created and script executed successfully.")

        # Close the document
        print("Closing the InDesign document after saving changes...")
        doc.Close(1)  # 1 = 保存后关闭，修正注释

    except Exception as e:
        print(f"An error occurred: {e}")

if __name__ == "__main__":
    create_indesign_document_with_text()

额外注意事项 #

• 字体可用性：确保InDesign中已安装"Arial"字体，若未安装需替换为系统中存在的字体（如"宋体"）。
• 路径替换：需将save_path和jsx_script_path替换为实际的本地路径。
• COM权限：运行Python脚本时需确保有足够权限访问InDesign COM接口，建议以管理员身份运行或关闭UAC限制。
