Requests_IDNAEncoder
云策文档标注
概述
Requests_IDNAEncoder 是一个用于 IDNA URL 编码的类，提供 Punycode 编码和 ASCII 转换功能，但当前 nameprep 实现不完整，不完全符合规范。
关键要点
- 类名：Requests_IDNAEncoder，用于处理 IDNA 编码相关任务。
- 主要方法包括 encode、to_ascii、punycode_encode 等，支持主机名编码和 UTF-8 到 ASCII 的转换。
- 注意事项：nameprep 方法目前未完全实现，可能影响 IDNA 规范的完全合规性。
- 参考规范：RFC3490（IDNA 规范）和 RFC3492（Punycode/Bootstrap 规范）。
