小编use*_*518的帖子

我正在尝试将now的日期戳转换为Unix TimeStamp,但是下面的代码似乎被点击但是然后跳转到我的应用程序的末尾,因为似乎不喜欢time.mktime部分.

from datetime import datetime
import time

now = datetime.now()
toDayDate = now.replace(hour=0, minute=0, second=0, microsecond=0)
newDate = time.mktime(datetime.strptime(toDayDate, "%Y-%m-%d %H:%M:%S").timetuple())
print(newDate)

我正在尝试为 Nestjs TypeORM 设置迁移，在我的文件中，TypeOrmModule.forRoot()我已添加了所需的迁移文件夹，但它不断将迁移添加到根文件夹。

TypeOrmModule.forRoot({
  type: 'mssql',
  host: 'test',
  port: 1,
  username: 'test',
  password: 'test',
  database: 'test',
  entities: [__dirname + '/**/entities/*{.ts,.js}'],
  synchronize: false,
  options: {
    useUTC: true,
  },
  migrations: [__dirname + '/**/migration/*.ts'],
  cli: {
    migrationsDir: __dirname + '/**/migration',
  },
})

我尝试创建服务，但是当我尝试添加任何可观察项时，会引发以下错误， Property 'map' is missing in type 'Observable<any[]>'.

以下是我的服务

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { environment } from 'environments/environment';
import { Observable } from 'apollo-client/util/Observable';
import { catchError } from 'rxjs/operators';
import { throwError } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class TestService {

  protected apiURL = 'http://localhost:3000';

  constructor(private http: HttpClient) {}

  getTestCount(): Observable<any[]> {
    return this.http
      .get<any[]>(`${this.apiURL}/test-count`)
      .pipe(
        catchError(err => {
          return throwError(new Error(err));
        })
      );
  }
}
