Google Cloud - BigQuery - PHP use proxy - php

Question

I created a PHP script to retrieve some datas from my Google Cloud Platform account. Below is how I did :
<?php
require __DIR__ . '/vendor/autoload.php';
use Google\Cloud\BigQuery\BigQueryClient;
putenv('GOOGLE_APPLICATION_CREDENTIALS=key.json');
$projectId = 'xxxxx';
$datasetId = 'xxxxxx';
$table = 'xxxxx';
$bigQuery = new BigQueryClient([
'projectId' => $projectId
]);
// etc...
Everything works fine on my local computer (WAMP) but when I migrate my script to my company production environment, there is a problem :
Fatal error: Uncaught exception
'Google\Cloud\Core\Exception\ServiceException' with message 'cURL
error 6: Couldn't resolve host 'www.googleapis.com'
In fact I was excepting this message because every time I use Curl, I need to set our company proxy info :
<?php
curl_setopt($curl, CURLOPT_HTTPPROXYTUNNEL, true);
curl_setopt($curl, CURLOPT_PROXY, 'xxx.xxx.xxx.xxx');
By the way, i'm 100% sure that googleapis.com is white-listed by our proxies... but how to do it with the BigQueryClient ? I searched in the official documentation, no way to find how to use a proxy.

Answer 1

I would try passing blindly these constructions to one of the connection builder classes, hopefully one picks this up
'restOptions' => [
'proxy', 'xxx.xxx.xxx.xxx'
]
on the other hand if you have a trace log you could see if Guzzle or something else is used. Consider opening an issue tracking at: https://github.com/GoogleCloudPlatform/google-cloud-php/issues

Answer 2

Bigquery uses www.googleapis.com as its endpoint.
The command line instructions have global flags to specify an address, password, port and user name regarding a proxy usage, however, for client libraries you'll need to verify the access with your infrastructure team.

Answer 3

Use php's putenv() to set the proxy before using BigQueryClient.
putenv('HTTPS_PROXY=192.168.1.1:8080');

Answer 4

use Google\Cloud\BigQuery\BigQueryClient;
use GuzzleHttp\Client;
use Psr\Http\Message\RequestInterface;
$guzzleClient = new Client();
$config = [
'projectId' => 'xxx',
'keyFilePath' => 'key_path',
'restOptions' => [
'proxy' => 'xxx.xxx.xxx.xxx:xx'
],
'authHttpHandler' => function (RequestInterface $request, array $options = []) use ($guzzleClient) {
return $guzzleClient->send(
$request,
$options + [
'proxy' => 'xxx.xxx.xxx.xxx:xx'
]
);
}
];
$bigQueryClient = new BigQueryClient($config);
It works for me with php library google/cloud-bigquery version 1.8.0
