先决条件
- 安装了near-cli
获取example代码并编译wasm
git clone https://github.com/near-examples/NFT
cd NFT
./build.sh
检查res下的wasm是否生成
创建账户
浏览器进入https://wallet.testnet.near.org/,输入用户名pld2(替换成你自己的用户名),保存好助记词
登录
登录方式一
near login
登录方式二
没有浏览器的登录方式,创建access key
near generate-key pld2.testnet --seedPhrase="助记词"
检查~/.near-credentials/testnet/pld2.testnet.json文件是否创建好
部署智能合约
为了更易于复制/粘贴，我们将为我们的帐户 ID 设置一个环境变量。
ID=pld2.testnet
检查环境变量是否生效
echo $ID
执行部署
near deploy --wasmFile res/non_fungible_token.wasm --accountId $ID
返回内容如下
