peer chaincode¶
peer chaincode コマンドは、管理者がピアに対してチェーンコードに関連する操作、
例えば、インストール、インスタンス化、呼び出し、パッケージング、クエリ、アップグレードを行うことを可能にします。
Syntax¶
peer chaincode コマンドには以下のサブコマンドがあります:
- install
- instantiate
- invoke
- list
- package
- query
- signpackage
- upgrade
それぞれのサブコマンドオプション（install、instantiate...）は、ピアに関連する異なるチェーンコード操作に関連しています。
例えば、ピアにチェーンコードをインストールするには peer chaincode install サブコマンドオプションを使用し、
ピアの台帳の現在の値をチェーンコードに問い合わせる (クエリする) には peer chaincode query サブコマンドオプションを使用します。
いくつかのサブコマンドはフラグ --ctor を取り、その値はキー 'Args' または 'Function' と 'Args' を持つ JSON 文字列でなければなりません。
これらのキーは大文字と小文字を区別しません。
JSON 文字列が Args キーだけを持つ場合、キーの値は配列であり、配列の最初の要素が呼び出す対象の関数名で、
それ以降の要素はその関数の引数です。
JSON 文字列が 'Function' と 'Args' の両方を持つ場合、Function の値は呼び出す対象の関数名で、
Args の値はその関数の引数の配列となります。
例えば、{"Args":["GetAllAssets"]} は {"Function": "GetAllAssets", "Args":[]} と等価です。
peer chaincode の各サブコマンドは、このトピックの各セクションでそのオプションとともに説明されています。
Flags¶
それぞれの peer chaincode サブコマンドには、
個々のサブコマンドに固有のフラグと、
すべての peer chaincode サブコマンドに関連するグローバルフラグの両方があります。
すべてのサブコマンドがこれらのフラグを使用するわけではありません。
例えば、query サブコマンドは --orderer フラグを必要としません。
個々のフラグについては、関連するサブコマンドで説明します。 グローバルフラグは以下の通りです。
--cafile <string>オーダリングサービスのエンドポイントのための PEM エンコードされた信頼できる証明書を含むファイルへのパス
--certfile <string>オーダリングサービスのエンドポイントとの相互 TLS 通信に使用する PEM エンコードされた X509 公開鍵を含むファイルへのパス
--keyfile <string>オーダリングサービスのエンドポイントとの相互 TLS 通信に使用する PEM エンコードされた秘密鍵を含むファイルへのパス
-oor--orderer <string><hostname or IP address>:<port>で指定されたオーダリングサービスのエンドポイント--ordererTLSHostnameOverride <string>オーダリングサービスのエンドポイントとの TLS 接続を検証する際に使用するホスト名オーバーライド
