Go语言服务网格egress：外部服务访问

Go语言服务网格egress：外部服务访问

1. Egress代理

package egress import ( "net/http" "net/url" ) type EgressProxy struct { dialer *net.Dialer transport *http.Transport } func NewEgressProxy() *EgressProxy { return &EgressProxy{ dialer: &net.Dialer{ Timeout: 30 * time.Second, }, transport: &http.Transport{ DialContext: func(ctx context.Context, network, addr string) (net.Conn, error) { return e.dialer.DialContext(ctx, network, addr) }, }, } } func (e *EgressProxy) RoundTrip(req *http.Request) (*http.Response, error) { return e.transport.RoundTrip(req) }

2. 外部服务配置

type ServiceEntry struct { Address string Ports []Port } type Port struct { Name string Port int } func NewServiceEntry(address string, ports ...Port) *ServiceEntry { return &ServiceEntry{ Address: address, Ports: ports, } }

3. 总结

Egress控制微服务对外部服务的访问，提供统一的管理和安全控制能力。
