How to consume my webservice with PHP - php

Question

I have a question ..
My app gives me the following information:
HTTP + JSON
The following are sample HTTP requests and responses. The placeholders shown need to be replaced with actual values.
POST /json/reply/Zona
HTTP/1.1
Host: equatepro.azurewebsites.net
Content-Type: application/json
Content-Length: length
{"zonaId":0,"nombre":"String","creadoPor":"String","creadoFecha":"/Date(-62135596800000-0000)/","modificadoPor":"String","modificadoFecha":"/Date(-62135596800000-0000)/","estado":"String","nota":"String","borrar":false}
AND then
The following routes are available for this service:
POST /api/zonas
PUT /api/zonas/{zonaId}
enter image description here
enter image description here
I'm trying to communicate with my webservice using PUT method
My code
<?php
$pantalla="zonas";
%id =8;
$url= "http: //miapp.com /api/zonas/8".$pantalla ;
$url = $url ."/" . $id;
// complete url http://miapp.com/api/zonas/8
//build json
$ConstructorJson = array(
'ZonaId' => $Datos['txt_codigo'],
'Nombre' => $Datos['txt_Nombre'],
'CreadoPor' => $Datos['txt_CreadoPor'],
'CreadoFecha' => $Datos['txt_CreadoFecha'],
'ModificadoPor' => $Datos['txt_ModificadoPor'],
'ModificadoFecha' => $Datos['txt_ModificadoFecha'],
'Estado' => $Datos['cbo_Estado'],
'Nota' => $Datos['txt_Notas']
);
$json = json_encode($ConstructorJson);
$opts = array(
"http" => array(
"method" => "PUT",
"header" => "Accept: application/xml\r\n",
"content" => $json
)
);
$context = stream_context_create($opts);
$response = file_put_contents($url,'8',false,$context);
?>
Give me the following error
Warning: file_put_contents(http: //miapp .com/api/zonas/8): failed to open >stream: HTTP wrapper does not support writeable connections in C:\xampp\htdocs\Codigo2.0\models\zonas.model.php on line 34
and nothing happens.

Answer 1

I would rather connect using PHP curl.
$ConstructorJson = array(
'ZonaId' => $Datos['txt_codigo'],
'Nombre' => $Datos['txt_Nombre'],
'CreadoPor' => $Datos['txt_CreadoPor'],
'CreadoFecha' => $Datos['txt_CreadoFecha'],
'ModificadoPor' => $Datos['txt_ModificadoPor'],
'ModificadoFecha' => $Datos['txt_ModificadoFecha'],
'Estado' => $Datos['cbo_Estado'],
'Nota' => $Datos['txt_Notas']
);
$json = json_encode($ConstructorJson);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http: //miapp.com/api/zonas/8/zonas",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "PUT",
CURLOPT_POSTFIELDS => $json
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache",
"Accept: application/xml\r\n",
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}

Answer 2

HTTP wrapper does not support writeable connections - basically, PHP is telling you "Hey, you can't use this function to write to a file that lives on the internet. How do you expect me to write a file # http: //miapp .com/api/zonas/8? Not gonna happen".
I assume what you're trying to do is to send a PUT request # that location to update a zonas resource with ID 8.
Solution
Consider using a proper HTTP client that can send actual HTTP request methods and conform to the HTTP spec.
My personal favourite inside PHP is Guzzle -
http://docs.guzzlephp.org/en/stable/. Guzzle is a standalone package and can be downloaded from their site. You can use it in any PHP project - without or without a framework.
With Guzzle, you'd do something like the following:
$client = new GuzzleHttp\Client();
$json = json_encode($ConstructorJson);
$headers = [
"Accept" => "application/xml\r\n"
]
$request = new Request('PUT', $url, ['body' => $json, 'headers' => $headers]);
$client->send($request);

I finally solved the problem (thank you Kyle O'Brien)
Code
<?php
// web service url + tabla + id
$url = "mywebservice.com/zonas/8";
$Datos = $_POST;
//create a array with dates
$ConstructorJson = array(
'Nombre' => $Datos['txt_Nombre'],
'CreadoPor' => $Datos['txt_CreadoPor'],
'CreadoFecha' => $Datos['txt_CreadoFecha'],
'ModificadoPor' => $Datos['txt_ModificadoPor'],
'ModificadoFecha' => $Datos['txt_ModificadoFecha'],
'Estado' => $Datos['cbo_Estado'],
'Nota' => $Datos['txt_Notas']
);
//convert array to json
$json = json_encode($ConstructorJson);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "PUT",
CURLOPT_POSTFIELDS => $json,
CURLOPT_HTTPHEADER => array(
'Accept: application/json',
'Content-Type: application/json',
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
?>
