KeyLogWriter不生效

[1992w]

使用基础库的http client通过设置KeyLogWriter可以用来保存密钥，像下面这样：

	client := http.Client{
		Transport: &http.Transport{
			TLSClientConfig: &tls.Config{
				KeyLogWriter: file,
			},
		},
	}

使用req.Client设置KeyLogWriter,密钥不会保存到文件中：

	tc := c.GetTLSClientConfig()
	tc.KeyLogWriter = file
	c.SetTLSClientConfig(tc)

看了下源码，是设置指纹时没有设置KeyLogWriter这个参数，加上就正常了:

func (c *Client) SetTLSFingerprint(clientHelloID utls.ClientHelloID) *Client {
	fn := func(ctx context.Context, addr string, plainConn net.Conn) (conn net.Conn, tlsState *tls.ConnectionState, err error) {
		colonPos := strings.LastIndex(addr, ":")
		if colonPos == -1 {
			colonPos = len(addr)
		}
		hostname := addr[:colonPos]
		utlsConfig := &utls.Config{
			ServerName:         hostname,
			RootCAs:            c.GetTLSClientConfig().RootCAs,
			NextProtos:         c.GetTLSClientConfig().NextProtos,
			InsecureSkipVerify: c.GetTLSClientConfig().InsecureSkipVerify,
			KeyLogWriter:       c.GetTLSClientConfig().KeyLogWriter, //这里加上就好了
		}
		uconn := &uTLSConn{utls.UClient(plainConn, utlsConfig, clientHelloID)}
		err = uconn.HandshakeContext(ctx)
		if err != nil {
			return
		}
		cs := uconn.Conn.ConnectionState()
		conn = uconn
		tlsState = &tls.ConnectionState{
			Version:                     cs.Version,
			HandshakeComplete:           cs.HandshakeComplete,
			DidResume:                   cs.DidResume,
			CipherSuite:                 cs.CipherSuite,
			NegotiatedProtocol:          cs.NegotiatedProtocol,
			NegotiatedProtocolIsMutual:  cs.NegotiatedProtocolIsMutual,
			ServerName:                  cs.ServerName,
			PeerCertificates:            cs.PeerCertificates,
			VerifiedChains:              cs.VerifiedChains,
			SignedCertificateTimestamps: cs.SignedCertificateTimestamps,
			OCSPResponse:                cs.OCSPResponse,
			TLSUnique:                   cs.TLSUnique,
		}
		return
	}
	c.Transport.SetTLSHandshake(fn)
	return c
}
