# 城市

添加一个 `城市` 参数，以缩小到城市级别的目标定位。例如， `cc-DE-city-munich` 表示来自德国慕尼黑的代理将处理该查询。 

{% hint style="info" %}
我们支持全球每一座城市，但由于移动代理的动态特性，我们无法保证在特定时刻那里一定有代理。最受欢迎的城市覆盖良好。
{% endhint %}

以下是一些有效的 `cc` 和 `城市` 参数组合示例：\
`cc-US-city-los_angeles`\
`cc-IT-city-rome`\
`cc-TH-city-bangkok`\
`cc-JP-city-tokyo`\
`cc-AU-city-sydney`\
`cc-ES-city-barcelona`

#### 代码示例

在此示例中，对 `ip.oxylabs.io` 从德国慕尼黑的随机 IP 地址执行：

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

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

{% endtab %}

{% tab title="PHP" %}

```php
<?php
$username = 'USERNAME';
$password = 'PASSWORD';
$country = 'DE';
$city = 'munich';
$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-cc-$country-city-$city:$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'
country = 'DE'
city = 'munich'
entry = ('http://customer-%s-cc-%s-city-%s:%s@pr.oxylabs.io:7777' %
    (username, country, city, 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-cc-DE-city-munich", "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;

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

{% 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-cc-DE-city-munich', 'PASSWORD')

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

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

puts result.body
```
