Intermediate Response headers not printed for Digest Auth

针对 digest-auth 端点运行提供的 HTTPie 命令，并将其与 curl 输出进行比较。跟踪 DigestAuthPlugin、requests.request 调用以及 --all/--print 处理如何表示中间响应；完成的标准是初始的 401 标头和最终的 200 响应都按文档所述显示。

Minimal reproduction code and steps

1. show with curl

curl https://httpbin.io/digest-auth/auth/user/pass -i --digest --user 'user:pass'
HTTP/1.1 401 Unauthorized
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Content-Type: application/json; charset=utf-8
Www-Authenticate: Digest qop=auth, realm="httpbin.io", algorithm=MD5, nonce=0466467c2af05e1dc3647666a0881e5f, opaque=dace930722adc22226b9b442aa01127f
Date: Fri, 04 Oct 2024 14:18:46 GMT
Content-Length: 52

HTTP/1.1 200 OK
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Content-Type: application/json; charset=utf-8
Date: Fri, 04 Oct 2024 14:18:46 GMT
Content-Length: 43

{
  "authorized": true,
  "user": "user"
}

2. show with http

http --verbose --print=HhBbm -A digest -a 'user:pass' --all https://httpbin.io/digest-auth/auth/user/pass
GET /digest-auth/auth/user/pass HTTP/1.1
Accept: */*
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Host: httpbin.io
User-Agent: HTTPie/3.2.3



HTTP/1.1 200 OK
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Content-Length: 43
Content-Type: application/json; charset=utf-8
Date: Fri, 04 Oct 2024 14:17:26 GMT

{
    "authorized": true,
    "user": "user"
}

The 401 Response is missing although I have specified --all and the documentation explicitely states that "The intermediary HTTP communication include followed redirects (with --follow), the first unauthorized request when HTTP digest authentication is used (--auth=digest), etc."

See https://httpie.io/docs/cli/viewing-intermediary-requestsresponses

Current result

The 401 Response is missing

Expected result

The 401 Response should be displayed

Debug output

Please re-run the command with --debug, then copy the entire command & output and paste both below:

http --debug --print=HhBbm -A digest -a 'user:pass' --all https://httpbin.io/digest-auth/auth/user/pass
