我有一个nodejs包，可以使用
在控制台中读取myapps.app({appId: '123'}).then(console.log); //return json result in console
我想使用可变结果来读取它：
var result = myapps.app({appId: '123'});
console.log(result);
但是它不起作用！

是一个异步函数，它返回一个promise，要在同步样式代码中使用它，必须像这样使用myapps.app语法
async/await但是请确保此代码包含var result = await myapps.app({appId: '123'})
console.log(result)
函数。
async或者像这样立即调用异步函数
async function() { ... }
这里有一种资源可以帮助您(async function() { ... })()
