获取请求源ip时，https会取得127.0.0.1，访问http是正常的

requestDetail._req.socket.remoteAddress 使用内网访问时会出现127.0.0.1，而外网没有问题。看到——req的_peername: { address: '::ffff:127.0.0.1', family: 'IPv6', port: 50939 }很疑惑，求解答

No source file or test is named. Reproduce the internal HTTP and HTTPS requests, then inspect requestDetail._req.socket.remoteAddress and the _req._peername values shown in the report. Done means explaining why HTTPS reports 127.0.0.1 or identifying a concrete correction, with coverage for the affected request path.
