To install 15 | it, simply add the following line to your Podfile: 16 | 17 | ```ruby 18 | pod 'KIDDNS' 19 | ``` 20 | 21 | Podfile中需要添加VIPKID的Spec源，以及阿里云的Spec源 22 | 23 | ```ruby 24 | source "https://github.com/VIPKID-OpenSource/Specs" 25 | source "https://github.com/aliyun/aliyun-specs" 26 | ``` 27 | 28 | ## 前提条件 29 | 30 | 需要拥有阿里云账号，并创建了开通HTTPDNS服务的应用。且阿里云控制台中配置好了app里需要开通HTTPDNS服务的域名。 31 | 32 | ## 使用方法 33 | 34 | 通过`CocoaPods`将`KIDDNS`库集成到工程后，只需简单配置，即可开始使用. 35 | 36 | 使用配置项初始化`HTTPDNS`服务，配置项包含阿里云应用的appId和appKey, 以及app需要预解析的域名列表。 37 | 38 | ```objc 39 | NSArray *presolvedHostlist = @[@"api.abc.com", @"gateway.abc.com"]; 40 | KIDDNSConfig *config = [KIDDNSConfig new]; 41 | config.accountId = 100000; 42 | config.key = @"your app key"; 43 | config.presolvedHosts = presolvedHostlist; 44 | [[DNSCenter defaultCenter] initializeDNSServiceWithConfig:config]; 45 | ``` 46 | 47 | *建议将初始化服务放在`didFinishLauch`中，尽可能放在网络请求之前。* 48 | 49 | 在app内部，你也可以针对某域名设置黑名单或者白名单，其规则是： 50 | * 如果域名在黑名单内，则该域名相关的请求不会走`HTTPDNS`服务； 51 | * 如果域名不在黑名单内，而在白名单内，则该域名相关的请求会尝试走`HTTPDNS`服务； 52 | * 如果域名既不在黑名单内，且不在白名单内，并且白名单不为空，则该域名相关请求不走`HTTPDNS`服务； 53 | * 如果域名既不在黑名单内，且不在白名单内，且白名单为空，则该域名相关请求会尝试走`HTTPDNS`服务； 54 | 55 | 黑白名单均是域名列表，支持正则匹配。 56 | 57 | ```objc 58 | [DNSCenter defaultCenter].whiteList = @[@".vipkid.com.cn",@"api.abc.com"]; 59 | ``` 60 | 61 | 当app不需要`KIDDNS`服务运行时，也可以通过`automaticDNS`属性关闭KIDDNS服务。关闭之后KIDDNS中的`NSURLProtocol`就不再起作用。 62 | 63 | ```objc 64 | [DNSCenter defaultCenter].automaticDNS = NO; 65 | ``` 66 | 67 | 初始化`KIDDNS`服务之后，`automaticDNS`默认开启。 68 | 69 | 在`KIDDNS`服务开启的情况下，每个经过KIDDNS服务的请求都会被记录其是否走了`HTTPDNS`服务，以及是否最终成功。接入方如果关心这类记录，可以实现一个遵循`KIDDNSLogger`协议的日志类，并将该类添加到`KIDDNS`的日志服务中。*KIDDNS本身并不保存这些记录，请求结束后，记录即被销毁。* 70 | 71 | ```objc 72 | @interface KIDLogger : NSObject 73 | 74 | @end 75 | 76 | @implementation KIDLogger 77 | 78 | - (void)logLevel:(KIDDNSLogLevel)level result:(KIDDNSResult *)result 79 | { 80 | NSLog(@"[DNSLog][%@] result: %@", @(level), result); 81 | } 82 | 83 | @end 84 | 85 | ... 86 | 87 | 88 | [[DNSCenter defaultCenter] addLogger:[KIDLogger new]]; 89 | 90 | ``` 91 | 92 | ## 容错重试 93 | 94 | KIDDNS在底层拿到了请求域名的IP后，才会对请求进行拦截并进行重写。如果使用IP的方式进行网络请求而导致请求失败，KIDDNS会尝试使用原域名的方式再发起一次网络请求，如果仍然失败，则请求最终以失败结束，如果请求成功，则对请求发起方来说，请求依然成功，对中间的失败过程无感。 95 | 96 | ## 注意事项 97 | 98 | *注意: 由于WKWebView页面及Cookie在HTTPDNS场景中很难处理，因此对于WebView请求KIDDNS并没有进行处理，仍然将使用系统默认的DNS服务* 99 | 100 | ## Author 101 | 102 | yiyangest, y31210@gmail.com 103 | 104 | ## License 105 | 106 | KIDDNS is available under the MIT license.
