I'm trying to recreate Post JSON from angular 2 to php but it doesn't work as there's nothing in the $_REQUEST
variable on php side
The code:
searchHttp({body}: any): Promise<any>
{
let headers = new Headers ({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers, method: "post" });
let test_this = {"search": "person"};
return this.http.post(this.post_url, JSON.stringify(test_this), options)
.toPromise()
.then(response =>
{
return response.text();
})
.catch(this.handleError);
}
Is there something I'm missing? I know that posts works with another format because I have that answered in another question.
Also, is http.request
better than http.post
?
Edit:
After much consultation with Angular/Javascript experts, they believe this is a php issue. So anyone with knowledge of how to accept JSON objects on php side will be gladly welcomed.
angular 2 client side part
ngOnInit() {
let body=Api+'product.php'+'?id=' + this.link_id;
this._callservice.callregister(body)
.subscribe( data => {
this.outputs=data;
},
error => console.log("Error HTTP Post"),
() => console.log("completed") );
}
}
call.service.ts
import {Injectable} from '@angular/core';
import {Router} from '@angular/router';
import {Http, Response, Headers, RequestOptions} from '@angular/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/observable/throw';
@Injectable()
export class AuthenticationService {
constructor(private _http:Http){}
postregister(api:any){
// console.log(api);
let headers = new Headers({'Content-Type':'application/x-www-form-urlencoded'});
let options = new RequestOptions({ headers: headers, method: "post"});
return this._http.get(api,options)
.map(res => res.json())
.catch(this.handleError);
}
private handleError (error: Response) {
console.error(error);
return Observable.throw(error.json().error || ' error');
}
}
Server side PHP make sure on server side you have these three lines in php code.
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: X-Requested-With');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
Php file:
<?php
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: X-Requested-With');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
$servername = "localhost";
$username1 = "root";
$password = "root";
$dbname = "product";
$e=array("error"=>1,"message"=>"Account Already Exists");
$accountCreated = array( "error" =>0,
"data" => array(
"username" => "amit" ,
"password" => "anypassword",
"role"=> "user",
"id" => "anyid" ) );
// Create connection
$conn = mysqli_connect($servername, $username1, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$username = $_GET["username"];
$Pass = $_GET["password"];
$role= $_GET["role"];
$sql="SELECT COUNT(*) as user FROM users WHERE username = '$username'";
$result = mysqli_query($conn,$sql);
$line = mysqli_fetch_assoc($result);
$count = $line['user'];
if($count!=0)
{
echo json_encode($e);
}
else
{
$sql="INSERT INTO users(username,password,role)VALUES('$username','$Pass','$role')";
$result=mysqli_query($conn,$sql);
$sql="select * from users where username ='$username'";
$result=mysqli_query($conn,$sql);
$line=mysqli_fetch_assoc($result);
{
$accountCreated['data']['username']=$line['username'];
$accountCreated['data']['password']=$line['password'];
$accountCreated['data']['role']=$line['role'];
$accountCreated['data']['id']=$line['id'];
}
echo json_encode($accountCreated);
}
?>
i hope this will work for you .. for json i guess you should pass as options and use json decode for values you get in options.
