我的 kmz 生成器应用程序未在远程用户的机器上显示自定义图标

Question

我使用 google places API 编写了一个 .kmz 文件生成器。该程序在我的本地机器上运行良好，但一旦我在 Azure 上启动它，用户在谷歌地球上打开时就不会收到自定义图标。它只显示中心带有红色 x 的白色框作为图标。我已经通过让远程用户将 .kmz 更改为 .zip 并解压缩文件以查看内容来验证图标正在与 kml 文件一起下载到 .kmz 文件中。他们在那里找到了 kml 文件和自定义图标 png 文件，所以它一定与我放置它的位置有关，或者 google earth 如何引用 kmz 中的图标......？我迷路了我已经尝试了一切。这是我的应用程序的主要部分：

只是想更新这个，因为我最终自己找到了答案。问题是 Bank Icon.png 需要位于名为“files”的目录中，我必须更新 kml_generator 以引用新位置。这是更新后的代码：

# Get the path of the current script
script_dir = os.path.dirname(os.path.abspath(__file__))

# Construct the path to the icon file
icon_filename = 'Bank Icon.png'
icon_path = os.path.join('files', icon_filename)

# Create the 'files' directory if it doesn't exist
files_dir = os.path.join(script_dir, 'files')
pathlib.Path(files_dir).mkdir(parents=True, exist_ok=True)

# Copy the 'Bank Icon.png' to the 'files' directory if it doesn't exist
icon_src_path = os.path.join(script_dir, icon_filename)
icon_dest_path = os.path.join(files_dir, icon_filename)
if not os.path.exists(icon_dest_path):
    shutil.copy(icon_src_path, icon_dest_path)
