在 PHP 中删除 Angular2 应用程序中的数据
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:
$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 insight/experience 与 Angular2/PHP 将不胜感激。
是的,http post 在 angular2 中的工作方式类似。既然你想使用 post,我猜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,"best practice"。
return this.http.delete(url)
.subscribe(
result => console.log(result),
error => console.error(error)
});
