TypeScript:try/catch踩坑：Object is of type ‘unknown‘

在Typescript to version 4.4配置中添加了useUnknownInCatchVariables属性，默认值为true

try {
    ...
} catch(e) {
    console.log(e.message) //报错Object is of type 'unknown'
}

解决：

try {
    ...
} catch(e) {
    console.log((e as Error).message)
}
or:

try {
    ...
} catch(e) {
    if (e instanceof Error) {
        console.log(e.message)
    }
}

或者在 tsconfig.json 中更改如下：

{
    "compilerOptions": {
        "strict": true,
        "useUnknownInCatchVariables": false
    }
}

代码007普通
