HarmonyOS 鸿蒙Next：rcp进行网络请求,request.configuration与 rcp.createSession({ requestConfiguration: requestConfig })中的configuration设置有什么不同吗

1,rcp进行网络请求时,在创建Request时,可以传Configuration,

const request = new rcp.Request(kHttpServerAddress, “GET”);

request.configuration = {

security: {

certificate: {

content: n,

type: “PEM”,

key: " ",

keyPassword: “”

}

}

}

2,在进行创建会话时,通过rcp.createSession()也可以添加Configuration

const requestConfig: rcp.Configuration = {

  tracing: {

    verbose: true,

  },

  proxy: “system”,

  dns: {

    dnsRules: [

      { host: “https://example.com”, port: 443, ipAddresses: [“192.168.1.1”, “192.168.1.2”] }

    ]

  },

  security: {

    certificate: {

      content: “-----BEGIN CERTIFICATE-----\n…”,

      type: “PEM”,

      key: “/path/dir/”, // 请根据自身业务对key进行修改

      keyPassword: “your-password”,

    }

  },

};

const session = rcp.createSession({ requestConfiguration: requestConfig });

以上两者传入的Configuration有什么区别吗,流程有什么问题吗
