使用https的golang http客户端空闲

我有一个http客户端空闲测试，如果我运行它，我总是通过https conn获得空闲conn。 日志在下面

=== RUN   TestWithOneClient2
work1 start
work1 Connection reused for {Conn:0xc0000a8058 Reused:false WasIdle:false IdleTime:0s} ,172.26.33.1:49356 => 58.250.137.36:80

我发现如果我更改

work1

请求url为

其工作原理如下所示

---通过：TestWithOneClient2（5.03s）
通过

它看起来总是在康涅狄格州

添加问题

我读了代码http/transport.go
从

cc获取https连接，错误：=t.connPool（）.GetClientConn（req，addr）

和
http连接从

idlecon映射[connectMethodKey][]*persistConn

他们之间似乎没有什么影响。

---

但是为什么它不能重用最后一个http连接。

“为什么ilde连接是https而不是最后一个连接？”您能尝试重新表述这个问题吗？我真的不明白你想问什么。“它看起来总是在康涅狄格州吗？”是的。你感到惊讶吗？如果是，为什么？我重新编辑了它。我想知道为什么它不能重用HTTP连接@我会更仔细地阅读代码@彼得
