Set proxy in Guzzle
提问by mohammad shafiee
I have a problem with set proxy in guzzle that a blank page was shown while with curl everything works perfect. The code that I used in guzzle and curl came below. What is wrong with this code: Guzzle:
我在 guzzle 中设置代理时遇到问题，显示空白页面，而 curl 一切正常。我在 guzzle 和 curl 中使用的代码如下。这段代码有什么问题：Guzzle：
use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;
require_once "vendor/autoload.php";
try {
$client = new Client();
$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
$response = $client->send($request, [
'timeout' => 30,
'curl' => [
'CURLOPT_PROXY' => '*.*.*.*',
'CURLOPT_PROXYPORT' => *,
'CURLOPT_PROXYUSERPWD' => '*:*',
],
]);
echo '</pre>';
echo($response->getBody());
exit;
} catch (RequestException $e) {
echo $e->getRequest();
if ($e->hasResponse()) {
echo $e->getResponse();
}
}
And The code with CURL:
以及带有 CURL 的代码：
$url = 'http://httpbin.org';
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
curl_setopt($ch, CURLOPT_PROXY, '*.*.*.*');
curl_setopt($ch, CURLOPT_PROXYPORT, *);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, '*:*');
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$page = curl_exec($ch);
echo $page;
Thanks.
谢谢。

As for Guzzle 6.
至于狂饮6。
Guzzle docsgive info about setting proxy for a single request
Guzzle 文档提供有关为单个请求设置代理的信息
$client->request('GET', '/', ['proxy' => 'tcp://localhost:8125']);
But you can set it to all requests when initializing client
但是你可以在初始化客户端时将其设置为所有请求
$client = new Client([
'base_uri' => 'http://doma.in/',
'timeout' => 10.0,
'cookie' => true,
'proxy' => 'tcp://12.34.56.78:3128',
]);
UPD. I don't know why, but I face a strange behaviour. One server with guzzle version 6.2.2 works great with config as above, and the other one with the same version receives 400 Bad RequestHTTP error from a proxy. It is solved with another config structure (found in docs for guzzle 3)
更新。我不知道为什么，但我面临着一种奇怪的行为。一台 guzzle 版本 6.2.2 的服务器与上面的配置配合得很好，而另一台具有相同版本400 Bad Request的服务器从代理收到HTTP 错误。它是用另一个配置结构解决的（在guzzle 3 的文档中找到）
$client = new Client([
'base_uri' => 'http://doma.in/',
'timeout' => 10.0,
'cookie' => true,
'request.options' => [
'proxy' => 'tcp://12.34.56.78:3128',
],
]);

Had the same problem right now , and all i needed to do was use curl array keys as constants instead of strings ..
现在遇到了同样的问题，我需要做的就是使用 curl 数组键作为常量而不是字符串。
$response = $client->send($request, [
'timeout' => 30,
'curl' => [
CURLOPT_PROXY => '*.*.*.*',
CURLOPT_PROXYPORT => *,
CURLOPT_PROXYUSERPWD => '*:*',
],
]);
See CURL options Keys , they are not strings anymore.
请参阅 CURL 选项 Keys ，它们不再是字符串。

for a proxy, if you have the username and password, you can use:
对于代理，如果您有用户名和密码，则可以使用：
$client = new GuzzleHttp\Client();
$res = $client->request("POST", "https://endpoint.com", [
"proxy" => "http://username:[email protected]:10",
]);
this worked with guzzle in php.
这在 php 中与 guzzle 一起使用。

For Guzzle6, I think the best way is to implement a middleware for setting proxy.
对于Guzzle6，我认为最好的方法是实现一个设置代理的中间件。
From Guzzle6 docs:
来自 Guzzle6 文档：
We can set proxy as below:
我们可以设置代理如下：
use Psr\Http\Message\RequestInterface;
use GuzzleHttp\HandlerStack;
use GuzzleHttp\Handler\CurlHandler;
use GuzzleHttp\Client;
use GuzzleHttp\Middleware;
use Util\Api;
function add_proxy_callback($proxy_callback) {
return function (callable $handler) use ($proxy_callback) {
return function (RequestInterface $request,$options) use ($handler,$proxy_callback) {
$ip = $proxy_callback();
$options['proxy'] = $ip;
return $handler($request,$options);
};
};
}
$stack = new HandlerStack();
$stack->setHandler(new CurlHandler());
$stack->push(add_proxy_callback(function() {
return Api::getIp(); //function return a ip
}));
$client = new Client(['handler'=>$stack]);
$response = $client->request('GET','http://httpbin.org/ip');
var_dump((string)$response->getBody());

The procedure for psr-7 may be different, but if you're using the standard way to instantiate a client,
psr-7 的过程可能会有所不同，但如果您使用标准方式来实例化客户端，
path\to\project\vendor\guzzlehttp\guzzle\src\Client.php, lines 164-170includes code to read the environment variables to see if HTTP_PROXY and HTTPS_PROXY are set on the current machine, and if yes, Guzzle will use those values.
path\to\project\vendor\guzzlehttp\guzzle\src\Client.php，第 164-170 行包含读取环境变量的代码，以查看当前机器上是否设置了 HTTP_PROXY 和 HTTPS_PROXY，如果是，Guzzle 将使用这些值。
Additionally, I had to set my HTTPS_PROXY = http://ip:port(not https), because our workplace proxy seems to handle both https and http requests via the http protocol.
此外，我必须设置我的 HTTPS_PROXY = http://ip:port（不是 https），因为我们的工作场所代理似乎通过 http 协议处理 https 和 http 请求。
The advantage of this configuration is that you don't have to chnge proxy settings in your source code.
这种配置的优点是您不必在源代码中更改代理设置。

$response = \Drupal::httpClient()->post($settings['base_url'] . 'api/search/', [
'verify' => true,
'body' => $post_data,
'headers' => [
'Content-type' => 'application/json',
],
'curl' => [
CURLOPT_SSLVERSION => CURL_SSLVERSION_TLSv1_2,
CURLOPT_PROXY => 'proxyip:58080'],
]
)->getBody()->getContents();
Set proxy/https in Guzzle and SSL its work perfect.
在 Guzzle 和 SSL 中设置代理/https 其工作完美。
