AnyProxy 无法解析请求方法为 VIEW 的请求

```
$ curl --proxy http://127.0.0.1:8001 \
-H ':method: VIEW' \
-H 'content-type: application/json' \
--data-binary '{"pin" : 8213,"id" : "0911D5D6-6354-21F7-9E0A-XXXXXXXXXXXX"}' \
-X VIEW \
'https://api.some.app.io/trial'
```
经过测试， anyproxy 无法解析请求方法为 VIEW 的请求，在 Charles 和 mitmproxy 可以正常解析。
并且遇到 VIEW 的请求， beforeSendRequest 都不会触发。

Reproduce the VIEW request with the provided curl command and trace how AnyProxy handles it before beforeSendRequest. Compare the request-method parsing path with the expected proxy flow; done means VIEW requests are parsed successfully and beforeSendRequest is triggered.
