# Fazendo solicitações

Aprenda os métodos de autenticação de Dedicated ISP Proxies, incluindo nome de usuário/senha e lista de permissões de IP. Configure portas e credenciais para solicitações de proxy sem interrupções.

Por padrão, os Proxies da Oxylabs e o Proxy Rotator usam uma autenticação básica [**autenticação HTTP**](https://en.wikipedia.org/wiki/Basic_access_authentication) que exige que você forneça um nome de usuário e uma senha. Você pode obter suas credenciais entrando em contato com seu Gerente de Conta Dedicado ou com nossa Equipe de Suporte em [**support@oxylabs.io**](mailto:support@oxylabs.io).

Também oferecemos suporte à autenticação com base em endereços IP permitidos; veja [**Lista de IPs permitidos**](/products/pt-br/proxies/dedicated-isp-proxies/enterprise/restful.md). Dependendo do seu método de autenticação, talvez seja necessário alterar a porta do proxy.

| Porta do proxy | Uso                                                                                                                                                                                                                                                                                            |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `60000`        | Esta porta é necessária com Proxies quando as credenciais de login são usadas (nome de usuário e senha). Ela também é usada com [**Proxy Rotator** ](/products/pt-br/proxies/dedicated-isp-proxies/enterprise/proxy-rotator-optional.md)com credenciais de login e IPs na lista de permissões. |
| `65432`        | Necessária com Proxies quando a autorização é feita por IPs na lista de permissões.                                                                                                                                                                                                            |

#### Exemplos de código

Se você quiser usar Dedicated ISP Proxies com o método de autenticação por nome de usuário e senha:

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

```shell
curl -x 1.2.3.4:60000 -U user1:pass1 http://ip.oxylabs.io/location
```

```php
<?php
    $username = 'user1';
    $password = 'pass1';
    $proxy = '1.2.3.4:60000';
    $query = curl_init('https://ip.oxylabs.io/location');
    curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($query, CURLOPT_PROXY, "http://$proxy");
    curl_setopt($query, CURLOPT_PROXYUSERPWD, "$username:$password");
    $output = curl_exec($query);
    curl_close($query);
    if ($output)
        echo $output;
?>
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

response = requests.get(
    'https://ip.oxylabs.io/location',
    proxies={'http': 'http://username:password@1.2.3.4:60000',
            'https': 'http://username:password@1.2.3.4:60000'}
)
print(response.text)
```

{% endtab %}

{% tab title="C#" %}

```csharp
using System;
using System.Net;

class Example
{
    static void Main()
    {
        var proxy = new WebProxy
        {
            Address = new Uri($"http://1.2.3.4:60000"),
            BypassProxyOnLocal = false,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential("username", "password")

        var handler = new HttpClientHandler
        {

        task.Wait();
        Console.WriteLine(task.Result);

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developers.oxylabs.io/products/pt-br/proxies/dedicated-isp-proxies/enterprise/making-requests.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
