本快速指南介绍了如何 使用 Python 将 URL 转换为 PDF。包括环境设置、步骤列表以及示例代码，帮助您完成 链接转 PDF（Python）。此外，您还将学习如何根据需求自定义输出 PDF 文件。
使用 Python 将网页转换为 PDF 的步骤
- 设置环境以使用 Aspose.PDF for Python via .NET 将 URL 转换为 PDF
- 定义网页 URL 并声明 HtmlLoadOptions 以自定义输出页面设置
- 发送 GET 请求到指定 URL 并以字节流获取网页内容
- 从网页流创建 PDF 文档
- 将输出文档保存为 PDF 文件
以上步骤详细说明了 如何使用 Python 将 URL 转换为 PDF。设置目标 URL、自定义 PDF 页面选项，并发送 GET 请求以获取网页内容。然后，将网页流加载到 Document 类对象并将其保存为 PDF 文件。
