这可能听起来很新,但我一直在关注angularjs组件的本教程.
我是组件的新手,我如何注入常量Utils或authService像我这样的组件?
app.component('tlOverallHeader', {
bindings: {
data: '='
},
templateUrl: 'js/indexTimeline/components/tl_overallHeader/templates/tl_overallHeader.html',
controller: function() {
this.ms = 'tlOverallheader!'
}
})

我正在学习,我想念setTimeoutGolang的Nodejs.我还没有读过多少,我想知道我是否可以像间隔或环回一样实现相同的功能.
有没有办法可以将它从节点写入golang?我听说golang处理并发很好,这可能是一些goroutines或者其他?
//Nodejs
function main() {
//Do something
setTimeout(main, 3000)
console.log('Server is listening to 1337')
}

我在kubernetes环境中运行分片mongodb,有3个分片,每个分片上有3个实例.出于某些原因,我的mongodb实例已被重新安排到另一台机器上.
问题是当一个mongodb实例被重新安排到另一个实例时,replica config它将被无效.导致此错误如下.
