我将我的合约部署到basic-erc 20.hash-rush.testnet帐户。它只是erc20扩展，在rust上实现了铸造和可燃烧扩展。
当我尝试拨打电话时，例如：

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet

我收到消息：

Scheduling a call: basic-erc20.hash-rush.testnet.inc_allowance({ "escrow_account_id": "facebook.testnet", "amount": "5" })
Receipt: baKLR7NHbUpSRgAr5GVdKXqkJs7PLKS6azHFz183wkN
        Failure [basic-erc20.hash-rush.testnet]: Error: Smart contract panicked: panicked at &#39;The required attached deposit is 33100000000000000000000, but the given attached deposit is is 0&#39;, src&#x2F;lib.rs:462:13

  panic_msg: "panicked at 'The required attached deposit is 33100000000000000000000, but the given attached deposit is is 0', src/lib.rs:462:13"
}

然后我发现我可以用**--gas**参数来连接gas。然后，我做了另一个tx：

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --gas 33100000000000000000000
Scheduling a call: basic-erc20.hash-rush.testnet.inc_allowance({ "escrow_account_id": "facebook.testnet", "amount": "5" })

所以我试着减少气体的量：

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --gas 33100000000000000      
Scheduling a call: basic-erc20.hash-rush.testnet.inc_allowance({ "escrow_account_id": "facebook.testnet", "amount": "5" })
Error:  InvalidTxError: {}

    at async Object.handler (/Users/bohdan_malkevych/.nvm/versions/node/v13.12.0/lib/node_modules/near-shell/utils/exit-on-error.js:37:9) {
  type: 'InvalidTxError'
}

而且它再次没有成功。
所有默认测试运行正常，没有任何错误。先谢谢你了！

您收到的原始错误消息是：
要求的附加存款是3310000000000000000000000000000，但给出的附加存款是0
请注意，这是来自合同本身。你可以看到抛出这个错误的行：

assert!(
    required_deposit <= attached_deposit,
    "The required attached deposit is {}, but the given attached deposit is is {}",
    required_deposit,
    attached_deposit,
);

使用near-cli时，可以在命令后添加--help，以查看可以传递哪些选项。near call --help返回大量信息;这里的相关位是：

near call <contractName> <methodName> [args]

Options:
    ...
    --gas                      Max amount of gas this call can use  [string] [default: "100000000000000"]
    --amount                   Number of tokens to attach  [string] [default: "0"]

您是否尝试过将gas保留为默认值，但将--amount设置为33100000000000000000000？命令看起来像：

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --amount "33100000000000000000000"

使用depositYocto为我工作。
您可以像这样重试该命令：

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --depositYocto "33100000000000000000000"
