example - Angular2 http.post valor de forma al servidor php

http post angularjs example

Question

Estoy tratando de enviar valores de formulario desde el proyecto Ionic2 (Mecanografía angular2) a un servidor php en el que enviaré correo de contacto.

No puedo obtener los valores que se supone que debo ...

Aquí está mi form.service.ts:

import {Injectable} from ''angular2/core'';
import {Http, Response} from ''angular2/http'';
import {Headers, RequestOptions} from ''angular2/http'';
import {Observable} from ''rxjs/Observable'';
@Injectable()
export class FormService {
constructor (private _http: Http) {}
private _contactUrl = ''http://localhost:8888/Server/email.php'';
// private _contactUrl = ''/email'';
sendMail(value: Object): Observable<any> {
const body = JSON.stringify(value);
let headers = new Headers();
headers.append(''Content-Type'', ''application/x-www-urlencoded'');
return this._http.post(this._contactUrl, body, {
headers : headers
}).map(res => res.json());
}
}

Que se utiliza desde mi función onSubmit en mi form.ts:

import { Page, NavController } from ''ionic-angular'';
import { Component } from ''angular2/core'';
import { FORM_DIRECTIVES, FormBuilder, ControlGroup, Validators, AbstractControl } from ''angular2/common'';
import { Http, Response, Headers } from ''angular2/http'';
import { Observable } from ''rxjs/Observable'';
import ''rxjs/Rx'';
import { FormService} from ''./form.service'';
@Page({
templateUrl: ''build/pages/form/form.html'',
directives: [FORM_DIRECTIVES],
providers: [FormService]
})
export class Form {
contactForm: ControlGroup;
company: AbstractControl;
name: AbstractControl;
prenom: AbstractControl;
phone: AbstractControl;
email: AbstractControl;
website: AbstractControl;
message: AbstractControl;
arrivee: AbstractControl;
projet: AbstractControl;
projets = [
{ id: 1, label: ''Site Internet'' },
{ id: 2, label: ''Site Intranet/Extranet'' },
{ id: 3, label: ''Développement PHP'' },
{ id: 4, label: ''Développement C#'' },
{ id: 5, label: ''Conception Base de Données'' },
{ id: 6, label: ''Tiers Maintenance Applicative'' },
{ id: 7, label: "Recrutement d''un collaborateur Handicapé" }
];
arrivees = [
{ id: 1, label: ''Internet'' },
{ id: 2, label: ''Recommandation'' },
{ id: 3, label: ''Evênement'' }
];
response: string;
value: any;
constructor(public nav: NavController, fb: FormBuilder, private _http: Http, private _formService: FormService) {
this.nav = nav;
// New controlGroup instance
this.contactForm = fb.group({
// Validators Rules for each field
// Champ XXX: ['''', ...] correspondants au [ngFormControl]="XXX" de la vue HTML (inpput)
name: ['''', Validators.compose([Validators.required, Validators.minLength(3), this.checkFirstCharacterValidator])],
prenom: ['''', Validators.compose([Validators.minLength(3), this.checkFirstCharacterValidator])],
company: ['''', Validators.compose([Validators.required, Validators.minLength(3), this.checkFirstCharacterValidator])],
projet: ['''', Validators.required],
arrivee: ['''', Validators.required],
phone: ['''', Validators.compose([Validators.required, Validators.minLength(10)])],
email: ['''', Validators.required],
website: ['''', Validators.minLength(3)],
message: ['''', Validators.compose([Validators.required, Validators.minLength(20)])]
});
this.name = this.contactForm.controls[''name''];
this.prenom = this.contactForm.controls[''prenom''];
this.company = this.contactForm.controls[''company''];
this.projet = this.contactForm.controls[''projet''];
this.arrivee = this.contactForm.controls[''arrivee''],
this.phone = this.contactForm.controls[''phone''],
this.email = this.contactForm.controls[''email''],
this.website = this.contactForm.controls[''website''],
this.message = this.contactForm.controls[''message'']
}
// Check if firt character is a number
checkFirstCharacterValidator(control: Control): { [s: string]: boolean } {
if (control.value.match(/^/d/)) {
return { checkFirstCharacterValidator: true };
}
}
onSubmit(value) {
this._formService.sendMail({value})
.subscribe(
response => this.response = response,
error => console.log(error)
);
}
}

Y en mi archivo email.php estoy tratando de obtener el POST:

<?php
header(''Content-type: application/json'');
if ($_SERVER[''REQUEST_METHOD''] == ''OPTIONS'') {
if (isset($_SERVER[''HTTP_ACCESS_CONTROL_REQUEST_METHOD'']))
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
if (isset($_SERVER[''HTTP_ACCESS_CONTROL_REQUEST_HEADERS'']))
header("Access-Control-Allow-Headers: {$_SERVER[''HTTP_ACCESS_CONTROL_REQUEST_HEADERS'']}");
exit(0);
}
$value = json_decode(file_get_contents(''php://input''));
// for test
echo $value->name;
?>

Revisé en la consola de Chrome, obtengo algo: Captura de pantalla de la consola

¿Cómo puedo obtener la publicación de angular2 en mi php? ¿Me estoy perdiendo de algo?

Answer 1

Puedo ver dos problemas en tu código:

• Usted crea un contenido JSON con JSON.stringify pero para formularios, necesita usar la clase URLSearchParams o crear el contenido de la cadena a mano.
• Su valor de tipo de contenido no es correcto. Es application/x-www-form-urlencoded y no application/x-www-urlencoded .

Esto es lo que deberías usar en su lugar:

sendMail(value: Object): Observable<any> {
const body = new URLSearchParams();
Object.keys(value).forEach(key => {
body.set(key, value[key]);
}
let headers = new Headers();
headers.append(''Content-Type'',
''application/x-www-form-urlencoded'');
return this._http.post(this._contactUrl, body.toString(), {
headers : headers
}).map(res => res.json());
}

Answer 2

Logré ponerlo en funcionamiento, solo fue:

 sendMail(value: any): Observable<any> {
const body = new URLSearchParams(value);
body.set(''name'', value.name);
body.set(''company'', value.company);
body.set(''projet'', value.projet);
body.set(''arrivee'', value.arrivee);
body.set(''phone'', value.phone);
body.set(''email'', value.email);
body.set(''website'', value.website);
body.set(''message'', value.message);
body.set(''name'', value.name);
let headers = new Headers();
headers.append(''Content-Type'', ''application/x-www-form-urlencoded'');
return this._http.post(this._contactUrl, body.toString(), {
headers : headers
}).map(res => res.json());
}

Y en form.php:

<?php header(''Access-Control-Allow-Origin: *'');
header(''Access-Control-Allow-Headers: X-Requested-With'');
header(''Access-Control-Allow-Methods: POST, GET, OPTIONS'');
$formData = json_decode(file_get_contents(''php://input''));
foreach ($formData as $key=>$value) {
$_POST[$key]=$value;
}
$formObject = $_POST[''name''];
(...) ?>

Gracias a Thierry Templier por su valiosa ayuda.

Answer 3

Quizás para alguien será útil. Tuve un problema con los objetos anidados, pasando a objetos PHP como este:

var obj = {
value: 1,
innerObj: {
title: "title",
innerObject: {
value: 1
}
}
};

Lo resolví usando el analizador de consultas

Ejemplo de uso:

//at top of you .ts file
let qs = require(''qs'');
return this.http.post(url, qs.stringify(data), {headers: this.postHeader})
.map((resp: Response) => resp.json())
.catch((error: any) => Observable.throw(error) || ''Server error'');

También será útil para objetos no anidados
