# 中国入口节点

```
https://a81298871.com:8000 - 香港
```

```
https://cnt9t1is.com:8000 - 北京
```

我们已在香港和北京地区配置了入口节点，以便从中国获得更好的连接。请注意，这是一个 HTTPS 代理节点。所有用户名参数都与常规入口节点相同。

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

```shell
curl -x cnt9t1is.com:8000 -U "customer-USERNAME:PASSWORD" https://ip.oxylabs.io/location
```

{% endtab %}

{% tab title="PHP" %}

```php
<?php
$username = 'USERNAME';
$password = 'PASSWORD';
$proxy = 'cnt9t1is.com:8000';
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($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@cnt9t1is.com:8000' %
    (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("cnt9t1is.com", 8000);
        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;

类 Example
{
    静态 void Main()
    {
        var client = new WebClient();
        client.Proxy = new WebProxy("cnt9t1is.com:8000");
        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('cnt9t1is.com', 8000, '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 %}

请注意，目前部分第三方工具无法与香港和北京入口节点配合使用。可与上述入口节点配合使用的第三方工具有：

1. [**Chrome 的 Oxy Proxy Extension**](/integrations/cn/proxy-integrations/residential-proxies-guides/oxy-proxy-extension-for-chrome.md)
2. [**SwitchyOmega**](/integrations/cn/proxy-integrations/residential-proxies-guides/switchyomega-1.md)
3. [**Shadowrocket**](/integrations/cn/proxy-integrations/residential-proxies-guides/shadowrocket.md)

我们目前正在修复其余集成，届时将支持 HTTPS 协议。

如果您从中国连接我们的住宅网络时，且使用所提供的入口节点仍有问题，请联系 [**support@oxylabs.io**](mailto:support@oxylabs.io)，我们会一起找到解决方案。
