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)
}

# queryBlock(), queryTransaction(), etc. Default: true
ledgerQuery: true

#[Optional] the number of blocks from the highest block number of a group of peers that a peer
#can lag behind and still be considered to be up-to-date. These peers will be sorted using the

# [Optional] resolverStrategy specifies the peer resolver strategy to use when connecting to a peer
# Possible values: [PreferOrg (default), MinBlockHeight, Balanced]
#
# PreferOrg:
# Determines which peers are suitable based on block height lag threshold, although will prefer the peers in the
# current org (as long as their block height is above a configured threshold). If none of the peers from the current org
# are suitable then a peer from another org is chosen.
# MinBlockHeight:
# Chooses the best peer according to a block height lag threshold. The maximum block height of all peers is
# determined and the peers whose block heights are under the maximum height but above a provided "lag" threshold are load
# balanced. The other peers are not considered.
# Balanced:
# Chooses peers using the configured balancer.
resolverStrategy: PreferOrg
# [Optional] balancer is the balancer to use when choosing a peer to connect to
# Possible values: [Random (default), RoundRobin]
balancer: RoundRobin
# [Optional] blockHeightLagThreshold sets the block height lag threshold. This value is used for choosing a peer
# to connect to. If a peer is lagging behind the most up-to-date peer by more than the given number of
# blocks then it will be excluded from selection.
# Note that this parameter is applicable only when minBlockHeightResolverMode is set to ResolveByThreshold.
# Default: 5
blockHeightLagThreshold: 2
# [Optional] reconnectBlockHeightLagThreshold - the event client will disconnect from the peer if the peer's
# block height falls behind the specified number of blocks and will reconnect to a better performing peer.
# Note that this parameter is only applicable if peerMonitor is set to Enabled (default).
# Default: 10
# NOTES:
# - Setting this value too low may cause the event client to disconnect/reconnect too frequently, thereby
# affecting performance.
reconnectBlockHeightLagThreshold: 5
# [Optional] peerMonitorPeriod is the period in which the connected peer is monitored to see if

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？
