这是我在syslog上的日志格式：
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { OnInit } from '@angular/core/src/metadata/lifecycle_hooks';
import { Observable } from 'rxjs/internal/Observable';
import { User } from './user';
import 'rxjs/add/operator/map';
@Injectable(
//providedIn: 'root'
)
export class SummaryService {
public baseurl = 'https://jsonplaceholder.typicode.com/posts'
constructor(private http: HttpClient) { }
getUsers(): Observable<User[]> {
return this.http.get<User[]>(this.baseurl);
}
}
因此，当我使用以下命令获取10分钟以上的日志，其内容为已删除时。空了。
命令：
