Question

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

$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')         
  }
}

任何有关Angular2 / PHP的见解/经验都将受到赞赏。

是的，http post在angular2中的工作方式类似。由于你想使用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)
       );
  }
}

您还可以发送删除请求，这将是“最佳做法”。

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