Android Studio 多版本地址切换

来源：互联网发布：js 瀑布流布局插件编辑：程序博客网时间：2024/06/05 05:42

在app开发过程中，从测试到发布至少有两个接口域名或者二级域名，以便区别开发版本与上线版本。因为在开发过程中是绝对不能影响到正式上线的版本。所以需要方便地切换测试接口地址和正式接口地址。

接下来介绍本人使用的方法，如果您们有更好的方式，请尽情交流哦。

前提：所有的接口域名都抽离出来，如下所示

/** * <pre> *     author : Haitao *     e-mail : haitao_ni@foxmail.com *     time   : 2017/05/16 *     desc   : 接口地址 *     version: 1.0 * </pre> */public class HttpInterface {    static String SERVICE_STOCK_OA = "/api/";    private static String getPrefixAuto() {        switch (BuildConfig.API_ENV) {            case 0:                return getPrefixHttps(GlobalVar.OA_HOST, GlobalVar.OA_PORT_HTTPS);            case 1:                return getPrefixHttp(GlobalVar.OA_HOST, GlobalVar.OA_PORT_HTTP);            default:                return getPrefixHttp(GlobalVar.OA_HOST, GlobalVar.OA_PORT_HTTP);        }    }    private static String getPrefixAuto(String sub) {        switch (BuildConfig.API_ENV) {            case 0:                return getPrefixHttps(GlobalVar.OA_HOST, GlobalVar.OA_PORT_HTTPS, sub);            case 1:                return getPrefixHttp(GlobalVar.OA_HOST, GlobalVar.OA_PORT_HTTP, sub);            default:                return getPrefixHttp(GlobalVar.OA_HOST, GlobalVar.OA_PORT_HTTP, sub);        }    }    private static String getPrefixHttp(String host) {        return String.format(Locale.CHINA, "http://%s", host);    }    private static String getPrefixHttp(String host, int port) {        return String.format(Locale.CHINA, "http://%s:%d", host, port);    }    private static String getPrefixHttp(String host, int port, String sub) {        return String.format(Locale.CHINA, "http://%s:%d%s", host, port, sub);    }    private static String getPrefixHttps(String host, int port) {        return String.format(Locale.CHINA, "https://%s:%d", host, port);    }    private static String getPrefixHttps(String host, int port, String sub) {        return String.format(Locale.CHINA, "https://%s:%d%s", host, port, sub);    }    public interface Stock {        String URL_HOST = getPrefixAuto();        String URL_PREFIX = getPrefixAuto(SERVICE_STOCK_OA);        String URL_QUOTATION_DETAIL = URL_PREFIX + "quotation";        String URL_QUOTATION_SIMPLE = URL_PREFIX + "quotation/list";        String URL_QUOTATION_MINUTES = URL_PREFIX + "quotation/minute";        String URL_QUOTATION_KLINE = URL_PREFIX + "quotation/k-line";        String URL_STOCK_INFO = URL_PREFIX + "purchase";        String URL_HOME_INDEX = URL_PREFIX + "index";        String URL_ALL_STOCK_LIST = URL_PREFIX + "stock-list";        String URL_MINE_STOCK_LIST = URL_PREFIX + "user-stock";        String URL_ADD_MINE_STOCK = URL_PREFIX + "user-stock/add";        String URL_REMOVE_MINE_STOCK = URL_PREFIX + "user-stock/destroy";        String URL_SERVICE_TIME = URL_PREFIX + "server/time";        String URL_QUERY_UPDATE = URL_PREFIX + "version-detection";        String URL_QUERY_TRADE_RANK = URL_PREFIX + "policy-release-list";        String URL_POLICY_RANK = URL_PREFIX + "trader";        String URL_POLICY_RANK_LOGINED = URL_PREFIX + "trader-with-followed";        String URL_QUERY_NOTICS = URL_PREFIX + "announcement-list";        String URL_NOTICE_DETAIL_PRE = URL_PREFIX + "announcement-content/";        String URL_CONFIG = URL_PREFIX + "configs";        String URL_BUY_CONTRACT = URL_PREFIX + "buy-agreement-list";        String URL_DEL_ALIAS = URL_PREFIX + "delete-alias";    } }

其中GlobalVar是地址切换的配置，其中最主要的是toggleServiceAddres(BuildConfig.API_ENV);中的BuildConfig.API_ENV，默认情况下BuildConfig中是没有API_ENV这个值的，这需要处理一下，GlobalVar代码如下

/** * <pre> *     author : Haitao *     e-mail : haitao_ni@foxmail.com *     time   : 2017/05/16 *     desc   :请求地址配置 *     version: 1.0 * </pre> */public class GlobalVar {    public static String OA_HOST;    public static int OA_PORT_HTTP = 0;    public static int OA_PORT_HTTPS = 0;    public static String TEST_HOST;    public static int TEST_PORT_HTTP = 0;    public static int TEST_PORT_HTTPS = 0;    public static int COLOR_RED_UP;    public static int COLOR_GREEN_DOWN;    public static int COLOR_GRAY;    static {        toggleServiceAddres(BuildConfig.API_ENV);    }    public static void toggleOperatingEnvironment(int sRunTimeHttp) {        toggleServiceAddres(sRunTimeHttp);    }    private static void toggleServiceAddres(int runTimeHttp) {        switch (runTimeHttp) {            case 0: {//测试地址                OA_HOST = "api.dullme.com";                OA_PORT_HTTPS = 443;                OA_PORT_HTTP = 80;                TEST_HOST = "nhtzj.com";                TEST_PORT_HTTPS = 443;                TEST_PORT_HTTP = 80;                break;            }            case 1: { //正式地址                OA_HOST = "api.zjzyjt.cn";                OA_PORT_HTTPS = 443;                OA_PORT_HTTP = 80;                break;            }            default: {            }        }    }}

在BuildConfig中的API_ENV值是通过gradle文件配置的自定义值，只需在app的build.gradle文件内的android内添加如下代码

  buildTypes {        debug {            buildConfigField "boolean", "LOG_DEBUG", "true"            buildConfigField "int", "API_ENV", "0"        }        release {            buildConfigField "boolean", "LOG_DEBUG", "false"            buildConfigField "int", "API_ENV", "1"        }    }

buildTypes是用于打包apk时选择打包的版本的配置信息。buildConfigField用于在BuildConfig中添加自定义值，其中第一个参数是添加值的类型，第二个值是新添值的名称，第三个参数是新添值的值。
build.gradle文件修改后需要点击“Sync Now“，或者是build一下。之后就可以直接调用BuildConfig类中新添的全局变量了。
之后调试时需要切换服务器地址，遍只要修改build.gradle中对应的值便可以了。

其中LOG_DEBUG是我用来控制log输出的控制变量
API_ENV变量的类型也可以根据各位的需求进行修改
