·接入准备
·初始化 HTTPDNS。代码示例如下：
SDK 初始化配置信息，具体请参见 Android SDK 接入。
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） 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 HTTPS 证书校验，请参见 unity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; } }
