英文:
Facing issues with typescript multi hierarchy key map pair
问题
我要的是这段代码在我尝试像这样做时能够平稳运行：dependencyMetric.MyService.failure或dependencyMetric.MyService.time，目前得到了很多对象和其他东西，不知道如何将其变成一个层次结构映射。
英文:
How do I change this structure so that I can get the values of this object like a map
this is my const object
const dependencyMetrics : {[dependancyName : string] : {[name : string] : MetricInfo }[]} = {
MyService : [{
failure : {
metric: new Metric({
namespace: 'namespace',
metricName: 'ABC'
}),
metricProperties: {
period: Duration.seconds(60),
statistic: 'Average'
}
},
time : {
metric: new Metric({
namespace: 'namespace',
metricName: 'age'
}),
metricProperties: {
period: Duration.seconds(60),
statistic: 'Average'
}
}
}]};
//I am using this also as a type :
type MetricInfo = {
metric : Metric;
metricProperties : MetricOptions;
}
What I want is this code to behave smoothly when I try some thing like : dependencyMetric.MyService.failure
or dependencyMetric.MyService.time
currently getting a lot of Objects and stuff don't know how to make this a hierarchy map

你目前的结构将 MyService 视为对象数组的键。这就是为什么在尝试访问 failure 或 time 时会得到意外的结果。
从我的理解，你希望 MyService 成为一个包含 failure 和 time 指标的对象键，而不是一个数组。
尝试这样做：
const dependencyMetrics : {[dependencyName : string] : {[name : string] : MetricInfo }} = {
MyService : {
failure : {
metric: new Metric({
namespace: 'namespace',
metricName: 'ABC'
}),
metricProperties: {
period: Duration.seconds(60),
statistic: 'Average'
}
},
time : {
metric: new Metric({
namespace: 'namespace',
metricName: 'age'
}),
metricProperties: {
period: Duration.seconds(60),
statistic: 'Average'
}
}
}
};
你的 `MetricInfo` 类型将保持不变
编辑:
首先，要将更多的服务添加到你的 dependencyMetrics 对象中，你只需要在对象中包含它们：
const dependencyMetrics : {[dependencyName : string] : {[name : string] : MetricInfo }} = {
MyService1 : {
// ...MyService1 的指标
},
MyService2 : {
// ...MyService2 的指标
},
// 添加所需的服务
};
然后，要动态访问特定服务的指标，你可以使用方括号表示法来获取与键关联的值：
let serviceName = 'MyService1'; // 更改为你想要的服务名称
let metricName = 'failure'; // 更改为你想要的指标
let specificMetric = dependencyMetrics[serviceName][metricName];
英文:
Your current structure treats MyService as a key for an array of objects. Which is why your getting unexpected results when trying to access failure or time
From what i understood, you want MyService to be a key for an object containing failure and time metrics, not an array.
Try this:
const dependencyMetrics : {[dependencyName : string] : {[name : string] : MetricInfo }} = {
MyService : {
failure : {
metric: new Metric({
namespace: 'namespace',
metricName: 'ABC'
}),
metricProperties: {
period: Duration.seconds(60),
statistic: 'Average'
}
},
time : {
metric: new Metric({
namespace: 'namespace',
metricName: 'age'
}),
metricProperties: {
period: Duration.seconds(60),
statistic: 'Average'
}
}
}
};
Your MetricInfo type will stay the same
Edit:
First, to add more services to your dependencyMetrics object, you can just include them in the object:
const dependencyMetrics : {[dependencyName : string] : {[name : string] : MetricInfo }} = {
MyService1 : {
// ...metrics for MyService1
},
MyService2 : {
// ...metrics for MyService2
},
// add as many services as you need
};
Then, to access the metrics of a specific service dynamically, you can use the bracket notation to get the value associated with a key:
let serviceName = 'MyService1'; // change this to the service name you want
let metricName = 'failure'; // change this to the metric you want
let specificMetric = dependencyMetrics[serviceName][metricName];
