登錄到對等網絡-hyperledger結構（eca.user）有什么問題？

Question

有人可以幫我嗎？ 我不確定對等網絡（超級賬本結構）的登錄出了什么問題。

在http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/ ，我按照有關安全功能的說明進行了操作。 我嘗試了所說的。 我做了流浪的ssh， cd $GOPATH/src/github.com/hyperledger/fabric/peer ，然后是

peer network login admin 

（membersrvc.yaml的默認文件）。

我確實嘗試了其他用戶名和密碼，但是由於顯示錯誤，它們均無效。 據我了解，當顯示錯誤時，將意味着用戶名和密碼不正確。 但是，我復制並粘貼了用戶名和密碼，但沒有成功。 我能否知道登錄對等網絡（hyperledger fabric-使用git bash）的用戶名和密碼有什么問題？

用戶名和密碼（eca.user-顯示用戶名和密碼）將顯示在下面（membersrvc.yaml）：

    eca:


              # This hierarchy is used to create the Pre-key tree, affiliations is the top of this hierarchy, 'banks_and_institutions' is used to create the key associated to auditors of both banks and
                # institu

tions, 'banks' is used to create a key associated to auditors of banks, 'bank_a' is used to create a key associated to auditors of bank_a, etc.
            affiliations:

                      - bank_c
                  institutions:
                      - institution_a
            users:
                    #
                    # The fields of each user are as follows:
                    #    <EnrollmentID>: <system_role (1:client, 2: peer, 4: validator, 8: auditor)> <EnrollmentPWD> <Affiliation> <Affiliation_Role> <JSON_Metadata>
                    #
                    # The optional JSON_Metadata field is of the following format:
                    #   { "registrar": { "roles": <array-of-role-names>, "delegateRoles": <array-of-role-names> } }
                    # The 'registrar' section is used to control access to registration of new users directly via the ECAA.RegisterUser GRPC call.
                    # (See the 'fabric/membersrvc/protos/ca.proto' file for the definition of ECAA.RegisterUser.)
                    # Note that this also controls who can register users via the client SDK.
                    #
                    # Only users with a 'registrar' section may be a registrar to register other users.  In particular,
                    # 1) the "roles" field specifies which member roles may be registered by this user, and
                    # 2) the "delegateRoles" field specifies which member roles may become the "roles" field of registered users.
                    # The valid role names are "client", "peer", "validator", and "auditor".
                    #
                    # Example1:
                    #    The 'admin' user below can register clients, peers, validators, or auditors; furthermore, the 'admin' user can register other
                    #    users who can then register clients only.
                    #
                    # Example2:
                    #    The 'WebAppAdmin' user below can register clients only, but none of the users registered by this user can register other users.

以下代碼將是我鍵入git bash以便登錄對等網絡（hyperledger架構）的代碼：

vagrant@hyperledger-devenv:v0.0.11-c6e56d6:/opt/gopath/src/github.com/hyperledger/fabric/peer$ peer network login admin

Enter password for user 'admin': Xurw3yU9zI0l

輸入密碼后，將出現以下錯誤：

2016/09/14 07:05:33 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051: getsockopt: connection refused"; Reconnecting to {"0.0.0.0:7051" <nil>}

Usage:
  peer network login <username> [flags]

Flags:

Global Flags:
      --logging-level string       Default logging level and overrides, see core.yaml for full syntax
      --test.coverprofile string   Done (default "coverage.cov")
  -v, --version                    Display current version of fabric peer server

vagrant@hyperledger-devenv:v0.0.11-c6e56d6:/opt/gopath/src/github.com/hyperledger/fabric/peer$

更新：是的，我能夠實現類似的目標

06:04:34.617 [crypto] RegisterClient -> INFO 017 Registering client [admin] with                               name [admin]...
06:04:34.737 [crypto] Info -> INFO 018 [client.admin]  Register crypto engine...
06:04:34.738 [crypto] Info -> INFO 019 [client.admin]  Register crypto engine...                              done.
06:04:34.739 [crypto] RegisterClient -> INFO 01a Registering client [admin] with                               name [admin]...done!

但是，我可以知道為什么我只能登錄一次嗎？ 例如，如果我想再次登錄admin，它不會提示您輸入密碼，並且會有類似這樣的內容

vagrant@hyperledger-devenv:v0.0.11-087d2ea:/opt/gopath/src/github.com/hyperledger/fabric/peer$ peer network login admin
vagrant@hyperledger-devenv:v0.0.11-087d2ea:/opt/gopath/src/github.com/hyperledger/fabric/peer$

Answer 1

您出錯的原因，

2016/09/14 07:05:33 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: dial tcp 0.0.0.0:7051: getsockopt: connection refused"; Reconnecting to {"0.0.0.0:7051" <nil>}

是沒有在0.0.0.0:7051運行的peer 。

這是你應該做的，

從織物目錄運行membersrvc第一（讀取此 ，然后在一個單獨終端，運行下面的命令以啟動關於如何設置CA） peer的方法，

CORE_SECURITY_ENABLED=true CORE_SECURITY_PRIVACY=true peer node start --peer-chaincodedev

請注意，我正在dev模式下運行它。

打開另一個終端並運行以下命令，

peer network login lukas

出現提示時輸入（或粘貼）密碼。

在第二個窗口（已啟動對等方）中，將看到以下輸出，

08:48:18.978 [crypto] RegisterClient -> INFO 01b Registering client [lukas] with name [lukas]...
08:48:19.179 [crypto] Info -> INFO 01c [client.lukas]  Register crypto engine...
08:48:19.181 [crypto] Info -> INFO 01d [client.lukas]  Register crypto engine...done.
08:48:19.183 [crypto] RegisterClient -> INFO 01e Registering client [lukas] with name [lukas]...done!

讓我知道是否有幫助。

Answer 2

問題“為什么我只能登錄一次？”第二部分的答案如下：

用戶只能擁有一張注冊證書。 會員服務將在第一個用戶登錄到網絡時生成唯一的注冊證書。 簽發注冊證書后，會員服務將通過覆蓋注冊密碼來“禁用”用戶帳戶。

在您的示例中，當您向同一對等方發送“ login”命令時，該對等方將檢查用戶是否已注冊，並且不會向會員服務發送任何請求。

在具有多個對等方的配置中，用戶只能登錄其中之一。 第二次嘗試通過另一個對等方登錄將導致：

Error: Error on client login: roc error: code = 2 desc = Identity or token does not match.
