如何使用ID数组在Angular 4中进行大规模删除

问题描述

我正在尝试进行大规模删除，以使我拥有要删除的ID的 Array< number> .我无法将此数组作为参数传递给方法 this._httpService.delete(uri，options). _httpService 的类型为 Http .

I'm trying to make a massive delete, in order to do that I have an Array<number> of the ids I want to delete. I can't pass this array as a parameter to the method this._httpService.delete(uri,options). The type of _httpService is Http.

因此，我正在循环数组并在循环内进行单个调用，但是每个调用都是异步的，并且在循环结束时我有一定的逻辑可以运行.

So I'm looping the array and inside the loop I'm making single calls, but each call is async and I have certain logic to run when the loop ends.

推荐答案

实际上，根据，例如:

http.delete('/api/something', new RequestOptions({
    headers: headers,
    body: anyObject    // this would contain your ids
}))

因此，您的应用程序不发出数百个请求，而仅发出一个带有所有ID的请求.

So instead of issuing hundreds of requests, have your app make just one with all ids in the body.
