"""修复 edge-tts 的 403 问题（微软 2026-10 更换 Edge Read Aloud 端点）。
|
||||
|
||||
【现象】
|
||||
合成语音时报：
|
||||
aiohttp.client_exceptions.WSServerHandshakeError: 403, message='Invalid response status'
|
||||
同时伴随这些特征（可用来确认不是自己的环境问题）：
|
||||
- `edge_tts --list-voices`（普通 HTTPS）仍然正常返回
|
||||
- 系统时钟已 NTP 同步，偏差在几秒内
|
||||
- edge-tts 已经是最新版（PyPI 上的 7.2.8）
|
||||
- 换网络 / 换机器同样 403
|
||||
|
||||
【原因】
|
||||
微软把 Edge Read Aloud 的「合成」端点从旧地址
|
||||
speech.platform.bing.com/consumer/speech/synthesize/readaloud/edge/v1
|
||||
迁到了新地址
|
||||
api.msedgeservices.com/tts/cognitiveservices/websocket/v1
|
||||
旧端点在 2026-10-10 起于多数地区开始返回 403，2026-10-12 起全球（含美国）
|
||||
全线 403。而 edge-tts 7.2.8（2025-12 发布）尚未跟进。
|
||||
上游讨论：https://github.com/rany2/edge-tts/issues/490
|
||||
上游修复：https://github.com/rany2/edge-tts/pull/491 （未合并）
|
||||
|
||||
【做法】
|
||||
把 edge_tts/constants.py 中的 WSS_URL 指向新端点。新端点同样接受旧 token，
|
||||
参数名改为 Ocp-Apim-Subscription-Key；Sec-MS-GEC / Sec-MS-GEC-Version
|
||||
继续沿用原来的 v1 形式即可，无需 v2 token。
|
||||
|
||||
【用法】
|
||||
python3 patch_edge_tts_403.py # 打补丁
|
||||
python3 patch_edge_tts_403.py --check # 只看当前状态，不改动
|
||||
python3 patch_edge_tts_403.py --verify # 打补丁后实际合成一段音频来验证
|
||||
python3 patch_edge_tts_403.py --revert # 还原成 edge-tts 的原始端点
|
||||
|
||||
【注意】
|
||||
重新安装或升级 edge-tts 会覆盖 constants.py，补丁随之丢失，重跑本脚本即可。
|
||||
新端点对同一 IP 有限流（429），脚本验证时会自动重试几次。
