# 托管Kratos应用
#### 概述
Kratos是轻量级Go微服务框架，包含大量微服务相关功能及工具，更多Kratos框架相关信息详见[Kratos官方文档](https://go-kratos.dev/docs/)。
#### 前提条件
创建ServiceComb引擎，请参考[创建ServiceComb引擎](https://support.huaweicloud.com/usermanual-cse/cse_usermanual_0005.html)。
#### 代码接入
- Provider端：
  ```
  package main
  import (
          "crypto/tls"
          "log"
          "net/url"
          "github.com/go-chassis/sc-client"
          "github.com/go-kratos/kratos/contrib/registry/servicecomb/v2"
          "github.com/go-kratos/kratos/v2"
  )
  func main() {
  c, err := sc.NewClient(sc.Options{
                  // EndPoints填写servicecomb中service center的地址
  Endpoints: []string{"127.0.0.1:30100"},
                  EnableSSL: true,
                  TLSConfig: &tls.Config{   
                      InsecureSkipVerify: true, 
                  },
  })
  if err != nil {
  log.Panic(err)
  }
  r := servicecomb.NewRegistry(c)
  app := kratos.New(
                  //需要传入注册实例的endpoint
                  kratos.Endpoint(&url.URL{Scheme: "{endpoint}"}),
                  //服务名
  kratos.Name("helloServicecomb"),
                  //接入servicecomb注册中心service center
  kratos.Registrar(r),
  )
  if err := app.Run(); err != nil {
  log.Fatal(err)
  }
  }
  ```
  
- Consumer端：
  ```
  package main
  import (
          "context"
          "crypto/tls"
          "log"
          "github.com/go-chassis/sc-client"
          "github.com/go-kratos/kratos/contrib/registry/servicecomb/v2"
           "github.com/go-kratos/kratos/v2/transport/grpc"
  )
  func main() {
  c, err := sc.NewClient(sc.Options{
                  EnableSSL: true,
                  TLSConfig:  &tls.Config{  
                      InsecureSkipVerify: true,
                  },
                  // EndPoints填写servicecomb中service center的地址
  Endpoints: []string{"127.0.0.1:30100"},
  })
  if err != nil {
  log.Panic(err)
  }
  r := servicecomb.NewRegistry(c)
  ctx := context.Background()
  conn, err := grpc.DialInsecure(
  ctx,
                  //Endpoint格式:<schema>://[namespace]/<service-name>
  grpc.WithEndpoint("discovery:///helloServicecomb"),
  grpc.WithDiscovery(r),
  )
  if err != nil {
  return
  }
  defer conn.Close()
  }
  ```
