Guzzle 422 Unprocessable Entity error - php

Question

I'm using browserstack screenshots API - https://www.browserstack.com/screenshots/api The following curl is working:
curl -u "username:password" -H "Content-Type: application/json" -H "Accept: application/json" -d '{"browsers": [{"os": "Windows", "os_version": "7", "browser_version": "8.0", "browser": "ie"}], "url": "http://google.com"}' http://www.browserstack.com/screenshots
However, when I try the same call call with guzzle I get 422 Unprocessable Entity error.
$client = new GuzzleHttp\Client();
$request = $client->post('http://www.browserstack.com/screenshots', [
'headers' => ['Content-type' => 'application/json'],
'auth' => ['username', 'password']
]
);
$data = ['browsers' => ['os' => 'Windows', 'os_version' => '7', 'browser_version' => '8.0', 'browser' => 'ie'], 'url' => 'http://google.com'];
$request->setBody($data);
$response = $request->send();
dd($response);
Can you suggest how to debug this issue?

Answer 1

I had a mistake in method. It should be $client->createRequest instead of $client->post
Also, I had a mistake in data being passed. Browsers should be array of arrays
There is another library that could be used with browserstack and guzzle: https://github.com/ksenzee/browserstack-screenshots-php
$client = new GuzzleHttp\Client();
$request = $client->createRequest('POST', 'http://www.browserstack.com/screenshots', [
'headers' => ['Content-type' => 'application/json'],
'auth' => ['user', 'pwd'],
'body' => '{"browsers": [
{"os": "Windows", "os_version": "7", "browser_version": "8.0", "browser": "ie"},
{"os": "android", "os_version": "4.4", "device": "HTC One M8", "browser": "Android Browser"}
],
"url": "http://www.lipsum.com"}'
]
);
$response = $client->send($request);
dd($response->json());

To send JSON to the Screenshots API, you would need to format it as a JSON string.
$client = new GuzzleHttp\Client();
$request = $client->post('http://www.browserstack.com/screenshots', [
'headers' => ['Content-type' => 'application/json'],
'auth' => ['username', 'access_key'],
'body' => '{"browsers": [
{"os": "Windows", "os_version": "7", "browser_version": "8.0", "browser": "ie"},
{"os": "android", "os_version": "4.4", "device": "HTC One M8", "browser": "Android Browser"}
],
"url": "http://www.lipsum.com"}'
]
);
You will then be able to view the progress on your BrowserStack Screenshots page.
For a guide on how to send POST requests using Guzzle, you can refer this documentation — https://media.readthedocs.org/pdf/guzzle/latest/guzzle.pdf.

In my case uses 'json' in options's argument (https://es.stackoverflow.com/questions/185183/porqu%C3%A9-guzzle-5-0-lanza-el-error-422-si-estoy-armando-bien-la-consulta#185192), example:
$client = new GuzzleHttp\Client(['base_url' => 'http://www.browserstack.com/']);
$request = $client->post('screenshots', [
'headers' => ['Content-type' => 'application/json'],
'auth' => ['username', 'access_key'],
'json' => '{"browsers": [
{"os": "Windows", "os_version": "7", "browser_version": "8.0", "browser": "ie"},
{"os": "android", "os_version": "4.4", "device": "HTC One M8", "browser": "Android Browser"}
],
"url": "http://www.lipsum.com"}'
]
);
