# 概述
 这个例子提供了调用solana 上部署的一个Counter， 以及通过typescript 客户端调用Solana合约Counter
## 1. RUST 工程开发和部署
### 1.1 配置cargo 输出路径, 方便管理target， 
- 原因：因为target往往占用空间比较大，每个项目都有target目录，导致占用空间的目录太分散，不好清理
- 方法：
  - 修改文件 ~/.bashrc
```shell
export CARGO_TARGET_DIR=~/.target
export PATH=$PATH:~/.target/release:~/.target/debug
```
  - 验证, 清理.target之后，重新编译，查看.target目录
```bash 
cargo clean
ls -al ~/.target
cargo build
ls -al ~/.target
```

### 1.2 构建项目
```bash
cargo build-sbf
ls ~/.target/deploy
```
### 1.3 部署项目 
rust 提供了一个rust counter程序，可以部署到solana网络
```bash
solana program deploy ~/.target/deploy/counter_program.so
```


## 2 client nodejs 模块，调用counter程序测试
### 2.1 npm 版本说明
-  构造用户账号first，second， 并且获得airdrop
  ```bash
    nvm use 18.20.8
    npm run build
  ```
### 2.2 配置当前solana环境
#### 2.2.1  env配置
  可以配置到client/.env下面
需要配置成localnet或devnet
```bash
ljl@ljl-lenovo:learn-solana$ cat client/.env
export SOLANA_ENV=localnet
```
#### 2.2.2 localnet测试 
  需要运行一个节点
  ```bash
  solana-test-validator
  ```

#### 2.2.3 devnet配置
  devent可以从helius注册一个apikey, 可以把这个环境变量配置到client/.env 里面
  ```bash
  export HELIUS_API_KEY=${yourKey}
  ```
### 2.3 代码说明

#### 2.3.1 [地址生成](./client/src/0.create_data.ts) 
  - 命令创建目录.key
  - 生成两个用户first,second ,保存secretkey 在~/.key/first.json 和 ~/.key/second.json
  - 创建counter程序需要的输入输入数据地址key   ~/.key/pda.json
  - 调用Counter，
#### 2.3.2 [分配空间并且调用Counter](./client/src/1.create_and_call.ts)
  - 计算租用空间需要的lamports
  - 创建pda地址对应的空间， 使用first 和 pda 调用counter
#### 2.3.3 [first用户 再次调用Counter](./client/src/2.call.ts)
  - 使用first 和 pda 调用counter
#### 2.3.4 [second用户 调用Counter](./client/src/3.call_by_other_account.ts)


## 3 使用其他程序访问PDA地址,修改数据
### 3.1 新程序说明
### 3.2部署新的的程序
```bash
ljl@ljl-lenovo:update$ solana program deploy  ~/.target/deploy/counter_program.so
Program Id: BTNheJyGqcb8cMNcEx2GF1zLNRHigHYMGZ9VdWPWh7kE

Signature: 3pPzt7YDjFHR9Kf9Q3DXWdHu5sX6qCNd9bNCi32SbRmwPW6dg5dubMVGS6BHmUfgRGWWKvkw5by2F5cPnXqExAZZ


ljl@ljl-lenovo:update$ solana program deploy  ~/.target/deploy/update_account.so
Program Id: 6JhVJe6sWG6LqfzpfB9Q4LD5CTAiPBTFSSk6YssKzzBy

Signature: 2fZen3h1SQBaVHt73MqxFksdeUMLxa3ApMctqJHRJjdUGFEEA4cKYBt7yxf9vtK3UFYtirnAwT4MfZoUZFaV88vN
```
### 3.3 测试用新程序
### 新程序说明
因为新程序update 需要访问counter 相同的数据结构，因此增加一个公共数据结构data项目,GreetingAccount 定义在data/src/lib.rs
```bash
ljl@ljl-lenovo:learn-solana$ tree -L 3 ./rust
./rust
├── Cargo.lock
├── Cargo.toml
└── programs
    ├── counter
    │   ├── Cargo.lock

    │   ├── Cargo.toml
    │   └── src
    └── update
        ├── Cargo.toml
        └── src
```

### 3.4 新程序执行结果
```shell

      throw new SendTransactionError({
            ^
