誰でもこれで私を助けることができますか？ピア ネットワーク (hyperledger fabric) のログインの何が問題なのかわかりません。
http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/のセキュリティ機能に関する注記の手順に従いました
。言われた通りにしてみました。私はvagrant sshを実行し
cd $GOPATH/src/github.com/hyperledger/fabric/peer、続いて
peer network login admin
(membersrvc.yaml のデフォルト ファイル)。
他のユーザー名とパスワードを試してみましたが、エラーが表示されたため、どれも機能しませんでした。私の理解では、エラーが表示された場合、ユーザーとパスワードが正しくないことを意味します。ただし、ユーザーとパスワードをコピーして貼り付けましたが、機能しませんでした。ピア ネットワーク (ハイパーレジャー ファブリック - git bash を使用) にログインするためのユーザーとパスワードの何が問題なのか教えてください。
ユーザーとパスワード (ユーザーとパスワードを示す eca.user) は、次の (membersrvc.yaml) に表示されます。
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:
banks_and_institutions:
banks:
- bank_a
- bank_b
- 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.

次のコードは、ピア ネットワーク (hyperledger fabric) にログインするために git bash に入力するものです。
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
パスワードを入力した後のエラーは次のとおりです。

しかし、なぜ一度だけしかログインできないのかわかりますか? たとえば、管理者に再度ログインしたい場合、パスワードの入力を求めるプロンプトは表示されず、次のようなメッセージが表示されます
