"""查我改的 _post 到底发出去什么坏请求。
|

|
||
线索：隧道日志每 16 秒（= 轮询间隔）刷：
|
||
Unsolicited response received on idle HTTP channel
|
||
Error code: 400 Message: Bad request syntax ('0').
|
||
"Bad request syntax ('0')" 很像 **chunked 编码的结尾**（0\r\n\r\n）
|
||
被当成请求行了 —— 也就是 http.client 用了 Transfer-Encoding: chunked，
|
||
而 Python 的 BaseHTTPRequestHandler 默认**不解析 chunked 请求体**。
|
||
|
||
这个测试：
|
||
1. 起本地 relay
|
||
2. 用 RelayLink._post 连打几次
|
||
3. 把 relay 收到的原始请求行/头打出来
