WebStorm 警告: Promise returned from xxx is ignored 解决办法
WebStorm 提示内容:
Promise returned from xxx is ignored less… (Ctrl+F1)
This inspection reports function calls that return a Promise that is not later used. These are usually unintended and indicate an error.
这是因为调用的函数加了async, 而 async 声明的函数返回的是一个promise.
在调用这个函数前加一个await声明就可以了, 同时await的这个方法段也要添加async声明才能生效.
async componentDidMount() {
await Common.checkSth();
}
还没有评论,来说两句吧...
