我的结构版本是1.1.0预览版,同伴,订购者,configtxgen是新生成的.

当我执行configtxgen工具时:

configtxgen -profile SoloOrdererGenesis -outputBlock genesis.block 
configtxgen -profile mych -outputCreateChannelTx channel-artifacts/mych.tx -channelID mych

它生成genesis.block和mych.tx,channelName是mych.

然后orderer以genesis.block开头,执行以下命令:

peer channel create -f mych.tx -o orderer.example.com:7050 -c mych

它抛出错误,

错误:出现意外状态:FORBIDDEN - 无法达到1个子策略的隐含阈值,需要1个剩余:权限被拒绝

哪一步错了？

我的configtx.yaml文件是:

从Fabric文档create-join-channel,当我执行命令时

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

它会返回以下消息的错误代码段:

在kotlin源代码中,我无法理解如何实现String.kt的长度,如下:

package kotlin                                                  
public class String : Comparable<String>, CharSequence {
companion object {}

/**
 * Returns a string obtained by concatenating this string with the string representation of the given [other] object.
 */
public operator fun plus(other: Any?): String

public override val length: Int

public override fun get(index: Int): Char

public override fun subSequence(startIndex: Int, endIndex: Int): CharSequence

public override fun compareTo(other: String): Int}

var len:Int = "abc".length; // len = 3 where to run the length??

在哪里实现长度函数？

当我启动orderer,peer node,然后我启动example01.go来实例化链代码,并指定:

peer.address 192.168.120.189:7051 
chaincode.id.name simple-token:1.0.0

example01.go的主要代码是:

func main() {
    viper.Set("chaincode.id.name","simple-token:1.0.0")
    err := shim.Start(new(SimpleChaincode))
    if err != nil {
        fmt.Printf("Error starting Simple chaincode: %s", err)
    }
}

在方法shim.Start()中,错误发生在下面的句子中:

err = chatWithPeer(chaincodename, stream, cc)//causes the error

但它显示错误: 未实现的desc =未知服务protos.ChaincodeSupport进程完成退出代码0

当我使用 Goland 1.0 EAP IDE 调试 Fabric 源代码 orderer 模块时，它可以调试并提示：

GOROOT=/usr/local/Cellar/go/1.8.3/libexec #gosetup
GOPATH=/Users/friends/Documents/VirtualMachine/share/gopath #gosetup
/usr/local/Cellar/go/1.8.3/libexec/bin/go build -i -o /private/var/folders/cg/mwzlhrjs5y55ny553g6xz9tr0000gn/T/___orderer_start -gcflags "-N -l" /Users/friends/Documents/VirtualMachine/share/gopath/src/github.com/hyperledger/fabric/orderer/main.go #gosetup

# command-line-arguments
orderer/main.go:76: undefined: NewServer
orderer/main.go:207: undefined: createLedgerFactory

调试配置如下：

事实上，NewServer 存在于 server.go 中

当我删除 server.go 和 util.go，并将代码移动到 main.go.It 工作。我认为可能是 GoLand 1.0 EAP BUG。

我对goroutine，用户线程和内核线程概念感到困惑

1. 从有效的介绍goroutine，那么os threads本文提到的是什么意思？是用户线程还是内核线程？

2. 我从go-scheduler论文中了解到M G P，为什么的数量P等于CPU的数量？如果所有的cpus用于go程序，但是os系统中的其他程序没有cpu线程要执行？

3. os系统生成了多少个内核线程？

docker run  -v /Users/xx/var/temp:/ -it alpine bash

但它提示：

invalid mount config for type bind: invalid specification: destination can't be /

为什么 alpine 主机目录无法挂载？

从Fabric MSP,admincert:

1.a folder admincerts to include PEM files each corresponding to an administrator certificate

signcerts:

a folder signcerts to include a PEM file with the node’s X.509 certificate

我的shell脚本如下:

#!/bin/bash
account0=0xf2de2e86b9b634f655e441a4e8353c9bf59352d7
passwd=123456
data={"jsonrpc":"2.0","method":"personal_unlockAccount","id":1,"params":[$account0,$passwd]}
echo $data

我的期望是(通知"):

{"jsonrpc":"2.0","method":"personal_unlockAccount","id":1,"params":[0xf2de2e86b9b634f655e441a4e8353c9bf59352d7,123456]}

不

{jsonrpc:2.0,method:personal_unlockAccount,id:1,params:[0xf2de2e86b9b634f655e441a4e8353c9bf59352d7,123456]}

:我不希望使用转义字符,怎么样？像内容插入到xml标签" <![CDATA[..."..]]>"
