# 发起请求

学习使用 Oxylabs 移动代理发起请求。掌握基本查询结构，并使用参数进行位置定向、城市选择和会话控制。

## 基本查询

基本查询只需传入 `用户名` 和 `密码`. 无需其他参数。此类查询将使请求从随机 IP 地址（代理）发出。每个新请求都会使用不同的代理。

### 代码示例

在此示例中，对 `ip.oxylabs.io` 从随机 IP 执行：

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

```shell
curl -x pr.oxylabs.io:7777 -U "customer-USERNAME:PASSWORD" https://ip.oxylabs.io/location
```

{% endtab %}

{% tab title="PHP" %}

```php
<?php
$username = 'USERNAME';
$password = 'PASSWORD';
$proxy = 'pr.oxylabs.io:7777';
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, "http://$proxy");
curl_setopt($query, CURLOPT_PROXYUSERPWD, "customer-$username:$password");
$output = curl_exec($query);
curl_close($query);
if ($output)
    echo $output;
?>
```

{% endtab %}

{% tab title="Python" %}

```python
import urllib.request
import random
username = 'USERNAME'
密码 = 'PASSWORD'
entry = ('http://customer-%s:%s@pr.oxylabs.io:7777' %
    (username, password))
query = urllib.request.ProxyHandler({
    'http': entry,
    'https': entry,
})
execute = urllib.request.build_opener(query)
print(execute.open('https://ip.oxylabs.io/location').read())
```

{% endtab %}

{% tab title="Java" %}

```java
package example;

import org.apache.http.HttpHost;
import org.apache.http.client.fluent.*;

public class Example {
    public static void main(String[] args) throws Exception {
        HttpHost entry = new HttpHost("pr.oxylabs.io", 7777);
        String query = Executor.newInstance()
            .auth(entry, "customer-USERNAME", "PASS")
            .execute(Request.Get("http://ip.oxylabs.io/location").viaProxy(entry))
            .returnContent().asString();
        System.out.println(query);
    }
}
```

{% endtab %}

{% tab title="C#" %}

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

class Example
{
    static void Main()
    {
        var client = new WebClient();
        client.Proxy = new WebProxy("pr.oxylabs.io:7777");
        client.Proxy.Credentials = new NetworkCredential("customer-USERNAME", "PASSWORD");
        Console.WriteLine(client.DownloadString("https://ip.oxylabs.io/location"));
    }
c
```

{% endtab %}

{% tab title="Ruby" %}

```ruby
require 'uri'
require 'net/http'

uri = URI.parse('https://ip.oxylabs.io/location')
proxy = Net::HTTP::Proxy('pr.oxylabs.io', 7777, 'customer-USERNAME', 'PASSWORD')

req = Net::HTTP::Get.new(uri.path)

result = proxy.start(uri.host,uri.port) do |http|
    http.request(req)
end

puts result.body
```

{% endtab %}
{% endtabs %}

单个 backconnect 代理允许你通过用户名中的附加参数选择特定国家/地区的代理。此方式也支持会话控制。以下是凭据结构示例：

`customer-USERNAME-cc-US-sessid-abcde12345:PASSWORD`

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers.oxylabs.io/products/cn/proxies/mobile-proxies/making-requests.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
