在PHP中的Angular2应用程序中删除数据


Delete data in Angular2 app in PHP

如何在Angular2应用程序中使用PHP代码从MySql数据库中删除数据?最接近的建议是Angular 1,如下所示:

$scope.deleteProduct = function(id){
    // ask the user if he is sure to delete the record
    if(confirm("Are you sure?")){
        // post the id of product to be deleted
        $http.post('delete_product.php', {
            'id' : id
        }).success(function (data, status, headers, config){
            // tell the user product was deleted
            Materialize.toast(data, 4000);
            // refresh the list
            $scope.getAll();
        });
    }
}

是否可以类似地使用post方法:

import { Injectable } from '@angular/core';
import { Http, Response, Headers } from '@angular/http';
import 'rxjs/Rx';
@Injectable()
export class HttpService {
  constructor(private  http: Http) {}
  deleteData() {
    return this.http.post('delete_record.php')         
  }
}

任何关于Angular2/PHP的见解/经验都将不胜感激。

是的,http帖子在angular2中的工作原理类似。既然你想使用post,我想你也想在请求中添加一个正文。

import { Injectable } from 'angular/core';
import { Http } from 'angular/http';
@Injectable()
export class HttpService {
  constructor(private  http: Http) {}
  deleteData(data: SomeObject) {
    let url = "delete_record.php";
    let body = JSON.stringify(data);
    return this.http.post(url, body)
       .subscribe(
          result => console.log(result),
          error => console.error(error)
       );
  }
}

您也可以发送删除请求,这将是"最佳实践"。

 return this.http.delete(url)
        .subscribe(
           result => console.log(result),
           error => console.error(error)
        });
