Referenční informace o konfiguraci Azure blockchain Workbench

Aplikace Azure blockchain Workbench jsou pracovní postupy s více stranami, které jsou definovány pomocí metadat konfigurace a kódu inteligentního kontraktu. Metadata konfigurace definují pracovní postupy vysoké úrovně a model interakce aplikace blockchain. Inteligentní kontrakty definují obchodní logiku aplikace blockchain. Workbench používá ke generování uživatelského prostředí aplikace blockchain kód konfigurace a inteligentního kontraktu.

Metadata konfigurace určují pro každou aplikaci blockchain následující informace:

• Název a popis aplikace blockchain
• Jedinečné role pro uživatele, kteří můžou pracovat s aplikací blockchain nebo se do ní zúčastnit
• Jeden nebo více pracovních postupů. Každý pracovní postup funguje jako Stavový počítač pro řízení toku obchodní logiky. Pracovní postupy mohou být nezávislé nebo vzájemně spolupracují.

Každý definovaný pracovní postup určuje následující:

• Název a popis pracovního postupu
• Stavy pracovního postupu. Každý stav je fáze v toku řízení obchodní logiky.
• Akce přechodu do dalšího stavu
• Role uživatelů, kterým se povoluje zahájení každé akce
• Inteligentní kontrakty, které reprezentují obchodní logiku v souborech kódu

Aplikace

Aplikace blockchain obsahuje metadata konfigurace, pracovní postupy a role uživatelů, kteří se můžou chovat nebo se zúčastnit v rámci aplikace.

Příklad najdete v tématu příklad konfiguračního souboru.

Pracovní postupy

Obchodní logika aplikace může být modelována jako Stavový počítač, který přijímá akci způsobí, že tok obchodní logiky se přesune z jednoho stavu do druhého. Pracovní postup je kolekce takových stavů a akcí. Každý pracovní postup se skládá z jedné nebo více inteligentních kontraktů, které reprezentují obchodní logiku v souborech kódu. Spustitelný kontrakt je instancí pracovního postupu.

Příklad najdete v tématu příklad konfiguračního souboru.

Typ

Podporované datové typy.

Příklad konfigurace typu Array

{
  "Name": "Quotes",
  "Description": "Market quotes",
  "DisplayName": "Quotes",
  "Type": {
    "Name": "array",
    "ElementType": {
        "Name": "int"
    }
  }
}

Použití vlastnosti Array typu

Definujete-li vlastnost jako pole typu v konfiguraci, je nutné zahrnout funkci get, která vrátí veřejnou vlastnost typu pole v hustotě. Například:

function GetQuotes() public constant returns (int[]) {
     return Quotes;
}

Příklad konfigurace typu String

{
  "Name": "description",
  "Description": "Descriptive text",
  "DisplayName": "Description",
  "Type": {
    "Name": "string"
  }
}

Příklad konfigurace typu Enum

{
  "Name": "PropertyType",
  "DisplayName": "Property Type",
  "Description": "The type of the property",
  "Type": {
    "Name": "enum",
    "EnumValues": ["House", "Townhouse", "Condo", "Land"]
  }
}

Použití typu výčtu v hustotě

Po definování výčtu v konfiguraci můžete použít typy výčtu v hustotě. Můžete například definovat výčet s názvem PropertyTypeEnum.

enum PropertyTypeEnum {House, Townhouse, Condo, Land} PropertyTypeEnum public PropertyType; 

Seznam řetězců musí být v rámci konfigurace a inteligentních kontraktů shodný s platnými a konzistentními deklaracemi v blockchain Workbench.

Příklad přiřazení:

PropertyType = PropertyTypeEnum.Townhouse;

Příklad parametru funkce:

function AssetTransfer(string description, uint256 price, PropertyTypeEnum propertyType) public
{
    InstanceOwner = msg.sender;
    AskingPrice = price;
    Description = description;
    PropertyType = propertyType;
    State = StateType.Active;
    ContractCreated();
}

Konstruktor

Definuje vstupní parametry pro instanci pracovního postupu.

Příklad konstruktoru

    {
      "Name": "description",
      "Description": "The description of this asset",
      "DisplayName": "Description",

  {
    "AllowedRoles": [],
    "AllowedInstanceRoles": [ "InstanceOwner" ],

Aplikační role

Aplikační role definují sadu rolí, které mohou být přiřazeny uživatelům, kteří chtějí v rámci aplikace jednat nebo se do ní zúčastnit. Aplikační role lze použít k omezení akcí a účasti v rámci aplikace blockchain a odpovídajících pracovních postupů.

Příklad aplikačních rolí

"ApplicationRoles": [
  {
    "Name": "Appraiser",
    "Description": "User that signs off on the asset price"
  },
  {
    "Name": "Buyer",
    "Description": "User that places an offer on an asset"
  }
]

Identifikátory

    "DisplayName": "Description",
    "Description": "Describes the asset being sold",
    "Type": {
      "Name": "string"
    }
  }
]

Příklad konfiguračního souboru

Přenos prostředků je scénář inteligentního kontraktu pro nákup a prodej prostředků s vysokou hodnotou, který vyžaduje inspektora a hodnocení. Prodejci můžou vypsat své prostředky vytvořením instance inteligentního kontraktu přenosu prostředků. Účastníci můžou nabídky dělat na základě akce v rámci inteligentních smluv a další strany mohou podniknout kroky ke kontrole nebo posouzení assetu. Jakmile je Asset označený jako zkontrolovaný a vyhodnocený, kupující a prodávající si tento prodej znovu potvrdí, než se smlouva nastaví na dokončeno. V každém okamžiku procesu mají všichni účastníci přehled o stavu kontraktu, jak je aktualizován.
