为什么我在合约上调用 change 方法时 NEAR 请求授权？

Question

我的 NEAR AssemblyScript 合约有一个更改方法，我从我的前端（浏览器）代码调用它。用户已经登录并且可以阅读合同上的视图方法。只有在尝试调用 change 方法后，用户才会收到 NEAR 钱包请求授权的提示。

如何在没有再次请求权限的提示下调用更改方法？

Answer 1

我正在回答我自己的问题，因为我花了一些时间试图弄明白。

当我在钱包上调用函数requestSignIn()时，我还必须指定合约名称。

import {
  connect,
  WalletConnection
} from 'near-api-js';

...

const near = await connect(nearConfig);
const wallet = new WalletConnection(near);
wallet.requestSignIn('dev-xxxx-yyyy'); // Need to pass the correct contract name to be able to call change methods on behalf of the user without requesting permission again

Answer 2

您还可以在此处查看一些示例：

这里基本上有2个接口：

// pass the contract name (as you did)
wallet.requestSignIn('dev-1634098284641-40067785396400');

// pass an object with contract and empty list of methods
wallet.requestSignIn({
  contractId: 'dev-1634098284641-40067785396400',
  methodNames: []
});

// add a list of methods to constrain what you can call
wallet.requestSignIn({
  contractId: 'dev-1634098284641-40067785396400',
  methodNames: ['write']
});

为什么我在合约上调用 change 方法时 NEAR 请求授权？

Why is NEAR requesting authorization when I call a change method on the contract?
