这篇文章指导你如何编译和部署 Move 合约到 starcoin 区块链。
Move 是一种新的编程语言，旨在为 [Diem 区块链]（https://github.com/deim/diem）提供安全和可编程的基础。 Starcoin Blockchain 还支持 Move 语言编写智能合约。
首先按照 Run/Join Network 中的描述启动一个开发网络，并获得一些测试硬币，比如"1000000000"。
然后，我们开始吧！
- 创建一个简单的模块，比如：
MyCounter.
module MyCounter {
use StarcoinFramework::Signer;
struct Counter has key, store {
value:u64,
}
public fun init(account: &signer){
move_to(account, Counter{value:0});
}
public fun incr(account: &signer) acquires Counter {
let counter = borrow_global_mut<Counter>(Signer::address_of(account));
counter.value = counter.value + 1;
}
public(script) fun init_counter(account: signer){
Self::init(&account)
}
public(script) fun incr_counter(account: signer) acquires Counter {
Self::incr(&account)
}
}
源文件位于 my-counter
- 编译模块
修改模块地址：
- 编辑
Move.toml - MyCounter = “0xABCDE” 改为 MyCounter = “0xb19b07b76f00a8df445368a91c0547cc”
在控制台中，运行：
$ mpm release
Packaging Modules:
0xb19b07b76f00a8df445368a91c0547cc::MyCounter
Release done: release/my_counter.v0.0.1.blob, package hash: 0xa7e3c02c102c85708c6fa8c9f84064d09cf530b9581278aa92568d67131c3b6d
它将编译模块，您将获得二进制包 3. 导入 0xb19b07b76f00a8df445368a91c0547cc 账号.
starcoin% account import -i 0x05c9d09cd06a49e99efd0308c64bfdfb57409e10bc9e2a57cb4330cd946b4e83 -p my-pass
{
"ok": {
"address": "0xb19b07b76f00a8df445368a91c0547cc",
"is_default": false,
"is_readonly": false,
"public_key": "0x7932502fa3f8c9bc9c9bb994f718b9bd90e58a6cdb145e24769560d3c96254d2",
"receipt_identifier": "stc1pkxds0dm0qz5d73zndz53cp28esyfj4ue"
}
}
- 部署模块 获得 devnet 测试币
dev get-coin 0xb19b07b76f00a8df445368a91c0547cc
解锁帐户
account unlock 0xb19b07b76f00a8df445368a91c0547cc -p my-pass
starcoin% dev deploy /guide-to-move-package-manager/my-counter/release/my_counter.v0.0.1.blob -s 0xb19b07b76f00a8df445368a91c0547cc -b

},

}
}
},
.....
....
}
- 调用 init_counter 脚本函数来初始化资源
starcoin% account execute-function --function 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::init_counter -s 0xb19b07b76f00a8df445368a91c0547cc -b

{

}
},
"raw": "0x265b0000000000000000000000000000"
}
}
},
.....
.....
}
- 查看资源
starcoin% state get resource 0xb19b07b76f00a8df445368a91c0547cc 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::Counter
{
"ok": {
"json": {
"value": 0
},
"raw": "0x0000000000000000"
}
}
- 调用 incr_counter 递增计数器
starcoin% account execute-function --function 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::incr_counter -s 0xb19b07b76f00a8df445368a91c0547cc -b
txn 0x7e8d6189c144c7640cbd79617247c0e242f52df6d60c74c29250492077b1b690 submitted.
{
"ok": {
"dry_run_output": {
"events": [],
"explained_status": "Executed",
"gas_used": "17231",
"status": "Executed",
"write_set": [
{
"access_path": "0x00000000000000000000000000000001/1/0x00000000000000000000000000000001::TransactionFee::TransactionFee<0x00000000000000000000000000000001::STC::STC>",
"action": "Value",
"value": {
"Resource": {
"json": {
"fee": {
"value": 34462
}
},
"raw": "0x9e860000000000000000000000000000"
}
}
},
......
......
}
- 再次查看资源
starcoin% state get resource 0xb19b07b76f00a8df445368a91c0547cc 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::Counter
{
"ok": {
"json": {
"value": 1
},
"raw": "0x0100000000000000"
}
}
你现在可以看到计数器的值是 1。
- 使用另一个帐户再次初始化和增加计数器
假设新账户地址为 0x0da41daaa9dbd912647c765025a12e5a
starcoin% account execute-function -s 0x0da41daaa9dbd912647c765025a12e5a --function 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::init_counter -b
starcoin% contract get resource 0x0da41daaa9dbd912647c765025a12e5a 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::Counter
starcoin% account execute-function -s 0x0da41daaa9dbd912647c765025a12e5a --function 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::incr_counter -b
starcoin% contract get resource 0x0da41daaa9dbd912647c765025a12e5a 0xb19b07b76f00a8df445368a91c0547cc::MyCounter::Counter
