Yii2 how to send form request to external url

Question

How to send a redirect post request to external url? my code in controller:

    if ($model->load(Yii::$app->request->post()) && $model->validate()) {
      // send post request to external link
    }

The answer is: you can't. You can save variables in session or build html form and autosubmit it by JavaScript. — Yupik, Jul 28 '18 at 11:08

@AntonRybalko Hi, because I want to redirect to a hosted page(which is an external link) and it requires a parameters to be sent via http post request form redirect. — Sean, Jul 30 '18 at 22:22
I can't use curl on this one since it needs to be redirected. — Sean, Jul 30 '18 at 22:23
You can post data with curl and after the successful response, you can redirect it to external Url. — akshaypjoshi, Aug 01 '18 at 05:09

You can redirect your request using HTTP 301

Yii::$app->response->redirect('url', 301);
Yii::$app->end();

Or use any php http clients like Guzzle (see How do I send a POST request with PHP?).

There is no other options.

301 redirection will loose POST data - you definitely don't want to do this. – rob006 Jul 31 '18 at 13:36
You can send post data as get parameters. Or send post request via php http client. See https://stackoverflow.com/questions/2604530/a-good-way-to-redirect-with-a-post-request – Anton Rybalko Aug 01 '18 at 00:47

You need to use 307 status code to specify redirection which should be performed with the same POST data.

$this->redirect('https://example.com', 307);

The HTTP 307 Temporary Redirect redirect status response code indicates that the resource requested has been temporarily moved to the URL given by the Locationheaders.

The method and the body of the original request are reused to perform the redirected request.

Hi Rob, thank you for this one. I can send my post request and gets redirected however the server isn't acknowledging my request, but when I use regular html form(not in yii2), it accepts my request. any thoughts on this? Cheers – Sean Aug 01 '18 at 05:13

Easily you can do it with Guzzle. From the documentation I think something like the below code is exactly what you want.

if ($model->load(Yii::$app->request->post()) && $model->validate()) {
    $response = $client->request('POST', 'http://httpbin.org/post', [
        'form_params' => [
            'field_name' => 'abc',
            'other_field' => '123',
            'nested_field' => [
                'nested' => 'hello'
            ]
        ]
    ]);
}

You can send data to the external server using CURL.

You can use the following code to send the post request to URL.

if ($model->load(Yii::$app->request->post()) && $model->validate()) {
        $url = 'http://www.example-redirect.com';
        $host = "http://www.example.com";
        $postData = Yii::$app->request->post();

        $ch = curl_init($host);
        $data = http_build_query($postData);

        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $response = curl_exec($ch);
        curl_close($ch);
        // Redirect from here
        return $this->redirect(Url::to($url));
    }

Hi, Thanks man, but it needs to be redirected to a hosted page. — Sean, Aug 01 '18 at 04:49
For Redirection, you can use Url Helper. `return $this->redirect(Url::to('https://www.example.com'));` — akshaypjoshi, Aug 01 '18 at 04:57
