如何解决智能契约的错误？

Question

我第一次尝试叫。请告诉我如何解决以下错误。

1. 我在帐户附近创建了Testnet。
2. 我用这个例子"https://github.com/near-examples/rust-counter/blob/master/contract/src/lib.rs"“编译了”计数器“契约。
3. 我已使用“近cli”将此合同部署到testnet，并取得了成功。
4. 我称之为近cli的"veiw函数“，错误返回。

Answer 1

Counter不是一个有效的帐户id.帐户内不允许大写字母-id。)。您需要传递正确的account-id。

我希望您的帐户id是某种形式的takahashi.testnet或dev-1623565709996-68004511819798 (如果契约是使用near dev-deploy命令部署的)。

这就是如何使用dev-deploy部署到testnet，以及如何使用near-cli调用视图函数。

❯ near --version
2.0.2

❯ near dev-deploy out/main.wasm
Starting deployment. Account id: dev-1623565709996-68004511819798, node: https://rpc.testnet.near.org, helper: https://helper.testnet.near.org, file: out/main.wasm
Transaction Id 5eTde2dUw5QTA8hbpWvAw4ABary64Tsnj9FzBCPS9Ne
Done deploying to dev-1623565709996-68004511819798

❯ near view dev-1623565709996-68004511819798 get_num '{}'
View call: dev-1623565709996-68004511819798.get_num({})
0

如果您使用的是mainnet网络(而不是testnet)，则需要通过设置环境变量让近-cli知道这一点：

❯ export NEAR_ENV=mainnet
