FutureSocket connectRustDeskRelay(String host, int port) async { try { // TLS加密连接底层走Flutter内置BoringSSL SecureSocket socket await SecureSocket.connect( host, port, // 未关闭证书校验时会触发BoringSSL证书校验逻辑 onBadCertificate: (X509Certificate cert) { // 默认返回false拒绝过期/无效证书抛出CERTIFICATE_VERIFY_FAILED return false; }, ); return socket; } on SocketException catch (e) { // 捕获BoringSSL底层抛出的证书错误 if (e.message.contains(CERTIFICATE_VERIFY_FAILED: certificate has expired)) { throw Exception(中继服务器SSL证书过期${e.message}); } rethrow; } }三、RustDesk Rust 后端原生 TLS 校验另一套触发同源错误代码RustDesk 核心服务端 / 桌面端使用rustls同样会报证书过期逻辑补充源码use rustls::{ClientConfig, RootCertStore, ServerName}; use std::net::TcpStream; use std::sync::Arc; fn tls_connect(host: str, port: u16) - Result(), Boxdyn std::error::Error { let mut root_store RootCertStore::empty();

tls_stream.flush()?; // 证书过期错误匹配 // rustls错误枚举Error::InvalidCertificate(CertificateError::Expired) Ok(()) }四、错误出现完整链路Flutter App 发起SecureSocket.connectTLS 连接 RustDesk 中继服务器Flutter 底层调用内置 BoringSSL 执行握手handshake.ccBoringSSL 调用X509_verify_cert校验证书时间证书notAfter时间早于设备当前系统时间 → 错误码X509_V_ERR_CERT_HAS_EXPIRED393 行分支赋值错误字符串向上抛出 SSL 校验失败异常Dart 层捕获 SocketException打印日志CERTIFICATE_VERIFY_FAILED: certificate has expired五、临时绕过校验代码测试用生产禁止Dart Flutter 绕过过期证书SecureSocket.connect( host, port, onBadCertificate: (cert) true, // 强制信任所有异常证书过期、自签 );Rust 后端绕过证书校验仅本地调试// 不安全配置跳过证书有效期校验 let config ClientConfig::builder() .with_custom_certificate_verifier(Arc::new(NoOpVerifier)) .with_no_client_auth();
