前言

简单记录集成阿里云HTTPDNS服务的过程

什么是HTTPDNS

HTTPDNS是面向多端应用（移动端APP，PC客户端应用）的域名解析服务，具有域名防劫持、精准调度、实时解析生效的特性。

以上来自阿里云HTTPDNS文档。

接入流程

服务开通

HTTPDNS是移动研发平台提供的服务，请参考EMAS 快速入门开通服务。

开通服务后，进入控制台，点击添加产品，如图所示

完成添加产品后，点击添加应用，如图所示
添加应用完成后，点击刚才添加的应用
查看Account ID,这个id后面配置dns会用到
在域名列表中添加域名

Android SDK 接入

在项目根目录下的build.gradle文件中添加Maven仓库地址

allprojects {repositories {maven {url 'http://maven.aliyun.com/nexus/content/repositories/releases/'}}
}

在需要引入HTTPDNS服务的模块下的build.gradle中添加依赖

dependencies {compile ('com.aliyun.ams:alicloud-android-httpdns:1.3.3@aar') {transitive true}
}

按照以上官方文档配置，在同步工程后，会报错

Could not find com.aliyun.ams:alicloud-android-utdid:1.1.5.4.
Searched in the following locations:- http://maven.aliyun.com/nexus/content/repositories/releases/com/aliyun/ams/alicloud-android-utdid/1.1.5.4/alicloud-android-utdid-1.1.5.4.pom- https://dl.google.com/dl/android/maven2/com/aliyun/ams/alicloud-android-utdid/1.1.5.4/alicloud-android-utdid-1.1.5.4.pom- https://jcenter.bintray.com/com/aliyun/ams/alicloud-android-utdid/1.1.5.4/alicloud-android-utdid-1.1.5.4.pom
Required by:project :app > com.aliyun.ams:alicloud-android-httpdns:1.3.3 > com.aliyun.ams:alicloud-android-beacon:1.0.4.3

修改如下

implementation('com.aliyun.ams:alicloud-android-httpdns:1.3.3@aar') {transitive trueexclude group: 'com.aliyun.ams', module: 'alicloud-android-utdid'
}
implementation 'com.aliyun.ams:alicloud-android-utdid:1.1.5.3'

引入Retrofit及gson

增加依赖

implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'
implementation 'com.google.code.gson:gson:2.8.6'

配置DNS

新建一个类，继承Dns

public class AliDns implements Dns {private HttpDnsService httpDns;public AliDns(Context context) {//传入account_id，account_id为HTTPDNS控制台添加应用时生成的httpDns = HttpDns.getService(context, "account_id");}@Overridepublic List<InetAddress> lookup(String hostname) throws UnknownHostException {//通过异步解析接口获取ipString ip = httpDns.getIpByHostAsync(hostname);//Android9.0系统及以后版本，https请求无法直接访问，方便起见，直接在AndroidManifest.xml中配置android:usesCleartextTraffic="true"if (ip != null) {//如果ip不为null，直接使用该ip进行网络请求Log.e("AliDns", "ip:" + ip);List<InetAddress> inetAddresses = Arrays.asList(InetAddress.getAllByName(ip));return inetAddresses;}//如果返回null，走系统DNS服务解析域名return Dns.SYSTEM.lookup(hostname);}
}

设置OkHttpClient的dns

OkHttpClient client = new OkHttpClient.Builder().dns(new AliDns(getApplicationContext())).build();

调用请求

Retrofit retrofit = new Retrofit.Builder().client(client).baseUrl("域名").addConverterFactory(GsonConverterFactory.create()).build();
Api api = retrofit.create(Api.class);
Call<Bean> call = api.getBanner();
call.enqueue(new Callback<Bean>() {@Overridepublic void onResponse(Call<Bean> call, Response<Bean> response) {if (!response.isSuccessful()) {tv.setText("请求失败，错误码:" + response.code());return;}Bean bean = response.body();tv.setText(bean.toString());}@Overridepublic void onFailure(Call<Bean> call, Throwable t) {tv.setText(t.getMessage());}
});
