# SUI Move开发必知必会——如何使用Sui TypeScript SDK进行交易发送和事件监听?

*rzexin 2024.04.14*

# 1 前言

`Sui TypeScript SDK`是一个用于与`SUI`区块链交互的模块化工具库。后续提及的`SDK`特指`Sui TypeScript SDK`。

本文将围绕**发送签名交易**和**获取合约事件**介绍涉及到的接口。

将要通过`SDK`进行交互的合约采用先前部署的**抢红包合约**，详细的介绍请参看：[《SUI Move合约学习与实践——抢红包合约（sui-red-packet）》](https://learnblockchain.cn/article/7772)

# 2 SDK介绍

## 2.1 官方文档

`SDK`的详细介绍及用法可以参看官方文档：https://sdk.mystenlabs.com/typescript

## 2.2 SDK包组成

`SDK`包含以下的库，开发者可以根据需要选择使用，本文将会涉及到的库有：`client`、`keypairs`、`transaction`、`utils`。

-   **`@mysten/suit.js/bcs`**：一个`BSC`构建器，具有预定义的`Sui`类型
-   **`@mysten/suit.js/client`**：用于与`Sui RPC`节点交互的客户端库
-   **`@mysten/sui.js/cryptography`**：用于加密的共享类型和类
-   **`@mysten/suit.js/faucet`**：水龙头库
-   **`@mysten/sui.js/keypairs`**：用于特定`KeyPair`实现的模块化导出
-   **`@mysten/sui.js/multisig`**：用于多签的库
-   **`@mysten/sui.js/transaction`**：用于构建交易和与交易交互的库
-   **`@mysten/suit.js/utils`**：工具类库
-   **`@mysten/sui.js/verify`**：用于验证交易和消息的库
-   **`@mysten/sui.js/zklogin`**：用于`zkLogin`库

## 2.3 SDK安装

>   `SDK`安装比较简单，在初始化好的`node.js`工程中执行如下命令安装`@mysten/sui.js`

-   **npm**

```bash
$ npm i @mysten/sui.js
```

-   **pnpm**

```bash
$ pnpm add @mysten/sui.js
```

-   **yarn**

```bash
$ yarn add @mysten/sui.js
```

# 3 交易发送

SDK中提供了两个发送签名交易的接口：`executeTransactionBlock`、`signAndExecuteTransactionBlock`。

前者进行交易签名和交易发送是分开的，后者交易签名和交易发送是二合一的。

将交易签名和交易发送分开，可以用于一些特殊场景，如离线签名、`zkLogin`签名等。

接下来，将具体介绍下这两个方法，再使用这两个方法分别调用抢红包合约中的两个主要合约接口：**发红包（`send_new_red_packet`)** 、 **抢红包（`claim_red_packet`）**。

## 3.1 接口说明

### 3.1.1 `executeTransactionBlock`

#### （1）函数功能

发送已签名交易。

#### （2）函数签名

```tsx
executeTransactionBlock(input: ExecuteTransactionBlockParams): Promise<SuiTransactionBlockResponse>;
```

#### （3）函数入参

-   `transactionBlock`：`BSC`序列化后的交易数据，格式为字节流或`base64`编码的字符串
-   `signature`：交易签名，`base64`编码的字符串
-   `requestType`：取值为`WaitForEffectsCert`或`WaitForLocalExecution`，确定`RPC`节点应何时返回响应
-   `option`：响应是否返回指定的信息，默认值都是`Fasle`，可选值为：`showBalanceChanges`、 `showEffects`、 `showEvents`、 `showInput`、 `showObjectChanges`、 `showRawInput`

```ts
/**
 * Execute the transaction and wait for results if desired. Request types: 1. WaitForEffectsCert: waits
 * for TransactionEffectsCert and then return to client. This mode is a proxy for transaction
 * finality. 2. WaitForLocalExecution: waits for TransactionEffectsCert and make sure the node executed
 * the transaction locally before returning the client. The local execution makes sure this node is
 * aware of this transaction when client fires subsequent queries. However if the node fails to execute
 * the transaction locally in a timely manner, a bool type in the response is set to false to indicated
 * the case. request_type is default to be `WaitForEffectsCert` unless options.show_events or
 * options.show_effects is true
 */
export interface ExecuteTransactionBlockParams {
    /** BCS serialized transaction data bytes without its type tag, as base-64 encoded string. */
    transactionBlock: Uint8Array | string;
    /**
     * A list of signatures (`flag || signature || pubkey` bytes, as base-64 encoded string). Signature is
     * committed to the intent message of the transaction data, as base-64 encoded string.
     */
    signature: string | string[];
    /** options for specifying the content to be returned */
    options?: RpcTypes.SuiTransactionBlockResponseOptions | null | undefined;
    /** The request type, derived from `SuiTransactionBlockResponseOptions` if None */
    requestType?: RpcTypes.ExecuteTransactionRequestType | null | undefined;
}
```

#### （4）函数出参

```tsx
export interface SuiTransactionBlockResponse {
    balanceChanges?: BalanceChange[] | null;
    /**
     * The checkpoint number when this transaction was included and hence finalized. This is only returned
     * in the read api, not in the transaction execution api.
     */
    checkpoint?: string | null;
    confirmedLocalExecution?: boolean | null;
    digest: string;
    effects?: TransactionEffects | null;
    errors?: string[];
    events?: SuiEvent[] | null;
    objectChanges?: SuiObjectChange[] | null;
    /**
     * BCS encoded [SenderSignedData] that includes input object references returns empty array if
     * `show_raw_transaction` is false
     */
    rawTransaction?: string;
    timestampMs?: string | null;
    /** Transaction input data */
    transaction?: SuiTransactionBlock | null;
}
```

### 3.1.2 `signAndExecuteTransactionBlock`

#### （1）函数功能

进行交易签名并发送交易。

#### （2）函数签名

```tsx
signAndExecuteTransactionBlock({ transactionBlock, signer, ...input }: {
        transactionBlock: Uint8Array | TransactionBlock;
        signer: Keypair;
    } & Omit<ExecuteTransactionBlockParams, 'transactionBlock' | 'signature'>): Promise<SuiTransactionBlockResponse>;
```

#### （3）函数入参

-   `transactionBlock`：`BSC`序列化后的交易数据，格式为字节流或`base64`编码的字符串
-   `signer`：`Keypair`对象用于交易签名
-   `requestType`：取值为`WaitForEffectsCert`或`WaitForLocalExecution`，确定`RPC`节点应何时返回响应
-   `option`：响应是否返回指定的信息，默认值都是`Fasle`，可选值为：`showBalanceChanges`、 `showEffects`、 `showEvents`、 `showInput`、 `showObjectChanges`、 `showRawInput`

#### （4）函数出参

同接口`executeTransactionBlock`。

## 3.2 代码说明

### 3.2.1 发红包（`send_new_red_packet`)

> 使用`executeTransactionBlock`实现发红包。

#### （1）代码实现

# 4 事件相关

`SDK`中提供了两种获取合约事件的方法，一种 **查询合约事件（`queryEvents`）** 、一种 **订阅合约事件（`subscribeEvent`）** 。

前者采用轮询方式查询特定事件，实时性不高；后者采用`Websocket`连接实时监听并获取链上事件，实时性较高。

但这两种方式可靠性似乎都不高，容易遗漏事件。

## 4.1 查询合约事件

### （1）接口定义

```tsx
    /**
     * Get events for a given query criteria
     */
    queryEvents(input: QueryEventsParams): Promise<PaginatedEvents>;
```

### （2）接口说明

-   该接口将根据给定条件查询事件
-   采用轮训查询方式，实时性不高，且会订阅到重复数据也容易遗漏订阅

### （3）代码实现

```ts
import { SuiClient } from "@mysten/sui.js/client";
import dotenv from "dotenv";
dotenv.config();
export const FULLNODE_URL: string = process.env.FULLNODE_URL!;
export const SUI_CLIENT = new SuiClient({ url: FULLNODE_URL });

async function queryEvents() {
  const eventType =
    "0xe5417558cf7edc87840fef347f294dc0fa7bdcd82c043e630c504d233c6b4784::red_packet::ClaimRedPacket<0x2::sui::SUI>";
  const events = await SUI_CLIENT.queryEvents({
    query: {
      MoveEventType: eventType,
    },
    order: "descending",
    limit: 1,
  });

events.data.forEach((event, index) => {
    console.log(`\nEvent Index: ${index}`);
    console.log(`    Transaction Digest: ${event.id.txDigest}`);
    console.log(`    Package ID: ${event.packageId}`);
    console.log(`    Event Sequence: ${event.id.eventSeq}`);
    console.log(`    Transaction Module: ${event.transactionModule}`);
    console.log(`    Sender: ${event.sender}`);
    console.log(`    Type: ${event.type}`);
    console.log(`    Parsed JSON: ${JSON.stringify(event.parsedJson)}`);
    console.log(`    BCS: ${event.bcs}`);
    console.log(`    Timestamp: ${event.timestampMs}`);
  });

setTimeout(queryEvents, 5000);
}

async function main() {
  await queryEvents();
}

main();
```

    Timestamp: 1713363283705
```

## 4.2 订阅合约事件

### （1）接口定义

```tsx
    /**
     * Subscribe to get notifications whenever an event matching the filter occurs
     */
    subscribeEvent(input: SubscribeEventParams & {
        /** function to run when we receive a notification of a new event matching the filter */
        onMessage: (event: SuiEvent) => void;
    }): Promise<Unsubscribe>;
```

### （2）接口说明

-   该接口将建立`Websocket`连接，实时监听链上事件，一旦有相关事件产生，便会触发
-   该接口实时性高，节省资源，但只能订阅实时事件，但可能会出现事件丢失的情况，可靠性不高（希望未来过滤器可以增加区块高度，可以指定从某一个区块开始进行订阅）

### （3）测试代码

```ts
import { SuiClient } from "@mysten/sui.js/client";
import dotenv from "dotenv";
dotenv.config();
export const WSS_URL: string = process.env.WSS_URL!;
export const SUI_WSS_CLIENT = new SuiClient({ url: WSS_URL });

async function subscribeEvent() {
  const eventType =
    "0xe5417558cf7edc87840fef347f294dc0fa7bdcd82c043e630c504d233c6b4784::red_packet::ClaimRedPacket<0x2::sui::SUI>";

process.on("SIGINT", async () => {
    console.log("Interrupted...");
    if (unsubscribe) {
      await unsubscribe();
    }
  });
}

async function main() {
  await subscribeEvent();
}

main();
```

SUI Move开发必知必会——如何使用Sui TypeScript SDK进行交易发送和事件监听?

rzexin 2024.04.14

1 前言

Sui TypeScript SDK是一个用于与SUI区块链交互的模块化工具库。后续提及的SDK特指Sui TypeScript SDK。

本文将围绕发送签名交易和获取合约事件介绍涉及到的接口。

将要通过SDK进行交互的合约采用先前部署的抢红包合约，详细的介绍请参看：《SUI Move合约学习与实践——抢红包合约（sui-red-packet）》

2 SDK介绍

2.1 官方文档

SDK的详细介绍及用法可以参看官方文档：https://sdk.mystenlabs.com/typescript

2.2 SDK包组成

SDK包含以下的库，开发者可以根据需要选择使用，本文将会涉及到的库有：client、keypairs、transaction、utils。

@mysten/suit.js/bcs：一个BSC构建器，具有预定义的Sui类型
@mysten/suit.js/client：用于与Sui RPC节点交互的客户端库
@mysten/sui.js/cryptography：用于加密的共享类型和类
@mysten/suit.js/faucet：水龙头库
@mysten/sui.js/keypairs：用于特定KeyPair实现的模块化导出
@mysten/sui.js/multisig：用于多签的库
@mysten/sui.js/transaction：用于构建交易和与交易交互的库
@mysten/suit.js/utils：工具类库
@mysten/sui.js/verify：用于验证交易和消息的库
@mysten/sui.js/zklogin：用于zkLogin库

2.3 SDK安装

SDK安装比较简单，在初始化好的node.js工程中执行如下命令安装@mysten/sui.js

npm

$ npm i @mysten/sui.js

pnpm

$ pnpm add @mysten/sui.js

yarn

$ yarn add @mysten/sui.js

3 交易发送

SDK中提供了两个发送签名交易的接口：executeTransactionBlock、signAndExecuteTransactionBlock。

前者进行交易签名和交易发送是分开的，后者交易签名和交易发送是二合一的。

将交易签名和交易发送分开，可以用于一些特殊场景，如离线签名、zkLogin签名等。

接下来，将具体介绍下这两个方法，再使用这两个方法分别调用抢红包合约中的两个主要合约接口：发红包（send_new_red_packet) 、 抢红包（claim_red_packet）。

3.1 接口说明

3.1.1 `executeTransactionBlock`

（1）函数功能

发送已签名交易。

（2）函数签名

executeTransactionBlock(input: ExecuteTransactionBlockParams): Promise&lt;SuiTransactionBlockResponse>;

（3）函数入参

transactionBlock：BSC序列化后的交易数据，格式为字节流或base64编码的字符串
signature：交易签名，base64编码的字符串
requestType：取值为WaitForEffectsCert或WaitForLocalExecution，确定RPC节点应何时返回响应
option：响应是否返回指定的信息，默认值都是Fasle，可选值为：showBalanceChanges、 showEffects、 showEvents、 showInput、 showObjectChanges、 showRawInput

/**
 * Execute the transaction and wait for results if desired. Request types: 1. WaitForEffectsCert: waits
 * for TransactionEffectsCert and then return to client. This mode is a proxy for transaction
 * finality. 2. WaitForLocalExecution: waits for TransactionEffectsCert and make sure the node executed
 * the transaction locally before returning the client. The local execution makes sure this node is
 * aware of this transaction when client fires subsequent queries. However if the node fails to execute
 * the transaction locally in a timely manner, a bool type in the response is set to false to indicated
 * the case. request_type is default to be `WaitForEffectsCert` unless options.show_events or
 * options.show_effects is true
 */
export interface ExecuteTransactionBlockParams {
    /** BCS serialized transaction data bytes without its type tag, as base-64 encoded string. */
    transactionBlock: Uint8Array | string;
    /**
     * A list of signatures (`flag || signature || pubkey` bytes, as base-64 encoded string). Signature is
     * committed to the intent message of the transaction data, as base-64 encoded string.
     */
    signature: string | string[];
    /** options for specifying the content to be returned */
    options?: RpcTypes.SuiTransactionBlockResponseOptions | null | undefined;
    /** The request type, derived from `SuiTransactionBlockResponseOptions` if None */
    requestType?: RpcTypes.ExecuteTransactionRequestType | null | undefined;
}

（4）函数出参

export interface SuiTransactionBlockResponse {
    balanceChanges?: BalanceChange[] | null;
    /**
     * The checkpoint number when this transaction was included and hence finalized. This is only returned
     * in the read api, not in the transaction execution api.
     */
    checkpoint?: string | null;
    confirmedLocalExecution?: boolean | null;
    digest: string;
    effects?: TransactionEffects | null;
    errors?: string[];
    events?: SuiEvent[] | null;
    objectChanges?: SuiObjectChange[] | null;
    /**
     * BCS encoded [SenderSignedData] that includes input object references returns empty array if
     * `show_raw_transaction` is false
     */
    rawTransaction?: string;
    timestampMs?: string | null;
    /** Transaction input data */
    transaction?: SuiTransactionBlock | null;
}

3.1.2 `signAndExecuteTransactionBlock`

（1）函数功能

进行交易签名并发送交易。

（2）函数签名

signAndExecuteTransactionBlock({ transactionBlock, signer, ...input }: {
        transactionBlock: Uint8Array | TransactionBlock;
        signer: Keypair;
    } & Omit&lt;ExecuteTransactionBlockParams, 'transactionBlock' | 'signature'>): Promise&lt;SuiTransactionBlockResponse>;

（3）函数入参

transactionBlock：BSC序列化后的交易数据，格式为字节流或base64编码的字符串
signer：Keypair对象用于交易签名
requestType：取值为WaitForEffectsCert或WaitForLocalExecution，确定RPC节点应何时返回响应
option：响应是否返回指定的信息，默认值都是Fasle，可选值为：showBalanceChanges、 showEffects、 showEvents、 showInput、 showObjectChanges、 showRawInput

（4）函数出参

同接口executeTransactionBlock。

4 事件相关

SDK中提供了两种获取合约事件的方法，一种 查询合约事件（queryEvents） 、一种 订阅合约事件（subscribeEvent） 。

前者采用轮询方式查询特定事件，实时性不高；后者采用Websocket连接实时监听并获取链上事件，实时性较高。

但这两种方式可靠性似乎都不高，容易遗漏事件。

4.1 查询合约事件

（1）接口定义

    /**
     * Get events for a given query criteria
     */
    queryEvents(input: QueryEventsParams): Promise&lt;PaginatedEvents>;

（2）接口说明

该接口将根据给定条件查询事件
采用轮训查询方式，实时性不高，且会订阅到重复数据也容易遗漏订阅

（3）代码实现

import { SuiClient } from "@mysten/sui.js/client";
import dotenv from "dotenv";
dotenv.config();
export const FULLNODE_URL: string = process.env.FULLNODE_URL!;
export const SUI_CLIENT = new SuiClient({ url: FULLNODE_URL });

async function queryEvents() {
  const eventType =
    "0xe5417558cf7edc87840fef347f294dc0fa7bdcd82c043e630c504d233c6b4784::red_packet::ClaimRedPacket&lt;0x2::sui::SUI>";
  const events = await SUI_CLIENT.queryEvents({
    query: {
      MoveEventType: eventType,
    },
    order: "descending",
    limit: 1,
  });

  events.data.forEach((event, index) => {
    console.log(`\nEvent Index: ${index}`);
    console.log(`    Transaction Digest: ${event.id.txDigest}`);
    console.log(`    Package ID: ${event.packageId}`);
    console.log(`    Event Sequence: ${event.id.eventSeq}`);
    console.log(`    Transaction Module: ${event.transactionModule}`);
    console.log(`    Sender: ${event.sender}`);
    console.log(`    Type: ${event.type}`);
    console.log(`    Parsed JSON: ${JSON.stringify(event.parsedJson)}`);
    console.log(`    BCS: ${event.bcs}`);
    console.log(`    Timestamp: ${event.timestampMs}`);
  });

  setTimeout(queryEvents, 5000);
}

async function main() {
  await queryEvents();
}

main();

    Timestamp: 1713363283705

4.2 订阅合约事件

（1）接口定义

    /**
     * Subscribe to get notifications whenever an event matching the filter occurs
     */
    subscribeEvent(input: SubscribeEventParams & {
        /** function to run when we receive a notification of a new event matching the filter */
        onMessage: (event: SuiEvent) => void;
    }): Promise&lt;Unsubscribe>;

（2）接口说明

该接口将建立Websocket连接，实时监听链上事件，一旦有相关事件产生，便会触发
该接口实时性高，节省资源，但只能订阅实时事件，但可能会出现事件丢失的情况，可靠性不高（希望未来过滤器可以增加区块高度，可以指定从某一个区块开始进行订阅）

（3）测试代码

import { SuiClient } from "@mysten/sui.js/client";
import dotenv from "dotenv";
dotenv.config();
export const WSS_URL: string = process.env.WSS_URL!;
export const SUI_WSS_CLIENT = new SuiClient({ url: WSS_URL });

async function subscribeEvent() {

  let unsubscribe = await SUI_WSS_CLIENT.subscribeEvent({
    filter: {
      MoveEventType: eventType,
    },
    onMessage: (event) => {
      console.log("Got Event");
      console.log(`    Transaction Digest: ${event.id.txDigest}`);
      console.log(`    Package ID: ${event.packageId}`);

      console.log(`    Timestamp: ${event.timestampMs}`);
    },
  });

  process.on("SIGINT", async () => {
