sdk实例化客户端时遇到报错

sdk相关代码如下:

package main

import (
	"fmt"
	"github.com/hyperledger/fabric-sdk-go/pkg/client/channel"
	"github.com/hyperledger/fabric-sdk-go/pkg/core/config"
	"github.com/hyperledger/fabric-sdk-go/pkg/fabsdk"
)

func main(){}

//封装全局变量
var (
	sdk *fabsdk.FabricSDK
	configFile = "./config.yaml"
	channelID = "testchannel"
	org = "Org1"
	user = "Admin"
	chaincodeID = "test"

	cli *channel.Client
)

func init(){
	//实例化sdk
	var sdkErr error
	sdk,sdkErr=fabsdk.New(config.FromFile(configFile))

	if sdkErr!=nil{
		panic(sdkErr)
	}

	//生成通道上下文环境
	ctx := sdk.ChannelContext(channelID,fabsdk.WithOrg(org),fabsdk.WithUser(user))

	//实例化客户端
	var cliErr error
	cli,cliErr=channel.New(ctx)
	if cliErr!=nil{
		panic(cliErr)
	}

	fmt.Println(cli)

}

sdk配置如下:

提问:
1、entityMatchers配置是否正确？
2、为何尝试连接peer2.org1.example.com:7051端口？(配置的是9051)
3、客户端在做什么？应该如何解决这个问题？

1 不对哈，我们首先看的是partten。你前三个partten都一样呢

2 因为你partten设置的不对，所以匹配了地一个设置，也就是7051

3 没懂什么意思。干什么？不是在初始化channel的cli么？解决什么问题？
