# Proxy Rotator - Opcional

Este serviço é opcional; se você quiser usar Proxy Rotator, entre em contato com seu Gerente de Conta para receber um domínio.

Em vez de se conectar a IPs individuais, fornecemos um único endpoint para sua lista de proxies atribuída. A cada solicitação, o endpoint busca um IP diferente. Veja o exemplo abaixo para aprender como usar o endpoint como um proxy.

{% hint style="info" %}
A [vm.oxylabs.io](http://vm.oxylabs.io) domínio é apenas um exemplo. Entre em contato com seu Gerente de Conta para obter um domínio encaminhado para você.
{% endhint %}

{% hint style="success" %}
Proxy Rotator deve ser usado apenas com a porta `60000`.
{% endhint %}

### Controle de sessão usando Proxy Rotator

É possível manter o mesmo endereço IP com o Proxy Rotator. Primeiro, você precisará saber quantos proxies o seu Proxy Rotator possui. Em seguida, adicione o `--proxy-header "Proxy-Server: sXXX"` cabeçalho à sua solicitação, onde `sXXX` é o número do proxy, por exemplo, `s5` ou `s2541`.

#### Exemplos de código

{% tabs %}
{% tab title="cURL" %}

```shell
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
user1@machine:~$ curl -x vm.oxylabs.io:60000 -U user1:pass1 https://ip.oxylabs.io/location --proxy-header "Proxy-Server: s10"
1.2.30.40
```

{% endtab %}

{% tab title="PHP" %}

```php
<?php
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, 'http://vm.oxylabs.io:60000');
curl_setopt($query, CURLOPT_PROXYUSERPWD, "username:password");
curl_setopt($query, CURLOPT_PROXYHEADER, [
    "Proxy-Server: s10",
]);

$output = curl_exec($query);
curl_close($query);
if ($output) {
    echo $output;
}
```

{% endtab %}

{% tab title="Python" %}

```python
import requests


class ProxyAdapter(requests.adapters.HTTPAdapter):
    def proxy_headers(self, proxy):
        headers = super(ProxyAdapter, self).proxy_headers(proxy)
        headers['Proxy-Server'] = 's10'
        return headers


s = requests.Session()
s.proxies = {'http': 'http://username:password@vm.oxylabs.io:60000',
             'https': 'http://username:password@vm.oxylabs.io:60000'}
s.mount('http://', ProxyAdapter())
s.mount('https://', ProxyAdapter())
response = s.get('https://ip.oxylabs.io/location')
print(response.text)
```

{% endtab %}

{% tab title="C#" %}

    {
        var client = new WebClient();
        client.Proxy = new WebProxy("http://vm.oxylabs.io:60000");
