接入准备
﻿获取 SDK 文件 并复制到 Unity 项目的 Assets/Plugins/Android目录中
初始化 HTTPDNS。代码示例如下：
 private static AndroidJavaObject sHttpDnsObj;
 public static void Init() {
     AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
     if (unityPlayerClass == null) {
         return;
     }	
     AndroidJavaObject activityObj = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");
     if (activityObj == null) {
         return;
     }
     AndroidJavaObject contextObj = activityObj.Call<AndroidJavaObject>("getApplicationContext");
     // 初始化 HTTPDNS
     AndroidJavaObject httpDnsClass = new AndroidJavaObject("com.tencent.msdk.dns.MSDKDnsResolver");
     if (httpDnsClass == null) {
         return;
     }
     sHttpDnsObj = httpDnsClass.CallStatic<AndroidJavaObject>("getInstance");
     if (sHttpDnsObj == null) {
         return;
     }
     
     // V4.0.0开始（推荐使用），具体可查看Android SDK接入﻿
     AndroidJavaObject dnsConfigBuilder = new AndroidJavaObject("com.tencent.msdk.dns.DnsConfig$Builder");
     dnsConfigBuilder.Call<AndroidJavaObject>("dnsId", "XXX");
     dnsConfigBuilder.Call<AndroidJavaObject>("dnsIp", "XXX");
     dnsConfigBuilder.Call<AndroidJavaObject>("dnsKey", "XXX");
     // 其他配置信息...
     AndroidJavaObject dnsConfig = dnsConfigBuilder.Call<AndroidJavaObject>("build");
      
     sHttpDnsObj.Call("init", contextObj, dnsConfig);
     
     // V4.0.0之前
     sHttpDnsObj.Call("init", contextObj, appkey, dnsid, dnskey, dnsIp, debug, timeout);
 }
调用 getAddrByName 接口解析域名。代码示例如下：
// 该操作建议在子线程中或使用 Coroutine 处理
// 注意在子线程中调用需要在调用前后做 AttachCurrentThread 和 DetachCurrentThread 处理 
public static string GetHttpDnsIP(string url) {
    string ip = string.Empty;
    AndroidJNI.AttachCurrentThread(); // 子线程中调用需要加上
    // 解析得到 IP 配置集合
    string ips = sHttpDnsObj.Call<string>("getAddrByName", url);
    AndroidJNI.DetachCurrentThread(); // 子线程中调用需要加上
    if (null != ips) {
        string[] ipArr = ips.Split(';');
        if (2 == ipArr.Length && !"0".Equals(ipArr[0]))
        ip = ipArr[0];
    }
    return ip;
}
IP 直连 HTPPS 证书校验，请参见 unity官方指引。代码示例如下：
 UnityWebRequest www = UnityWebRequest.Get(url);
 www.certificateHandler = new CertHandler();
 yield return www.SendWebRequest();
   
 // CertHandler是一个自定义的证书处理器类，重写ValidateCertificate方法，实现自定义的证书验证逻辑。 
 public class CertHandler : CertificateHandler
 {
     protected override bool ValidateCertificate(byte[] certificateData)
     {
         X509Certificate2 certificate = new X509Certificate2(certificateData);
         X509Certificate2Collection collection = new X509Certificate2Collection();
         collection.Import(Application.dataPath + "/Certificates/server.cer");
         return certificate.Issuer == collection[0].Issuer;
     }
 }
