Retrofit 2在开发中进行更改多个baseurl

多API下的调试，如果每次都改变API然后去重新打包.apk，会比较痛苦，在调试过程中，如果要进行验证API是否成功，可以在运行时改变API达到运行一次验证各API。

/*

public class ServiceGenerator {

    private static String BASE_URL = "http://api.juheapi.com/";

    private static Retrofit.Builder builder =
            new Retrofit.Builder()
                    .addConverterFactory(GsonConverterFactory.create())
                    .baseUrl(BASE_URL);

    public static  T createServiceFrom(Class serviceClass) {
        return builder.build().create(serviceClass);
    }
}

在上面这个类里面，进行来添加更改baseurl的代码

public static void changeApiBaseUrl(String newApiBaseUrl) {
    BASE_URL = newApiBaseUrl;

    builder = new Retrofit.Builder()
            .addConverterFactory(GsonConverterFactory.create())
            .baseUrl(BASE_URL);
}

使用方式:

public void getToh(String key, String version, String month, String day, Callback callBack) {
    mWeChatQuery = ServiceGenerator.createServiceFrom(WeChatQueryService.class);
    Call call = mWeChatQuery.getToh(key,version,month, day);
    call.enqueue(callBack);
}

public void getWeChatQuery(String key, Callback callback) {
    ServiceGenerator.changeApiBaseUrl(ApiAddressPool.API_JUHE_WECHAT);//改变API
    mWeChatQuery = ServiceGenerator.createServiceFrom(WeChatQueryService.class);
    Call call = mWeChatQuery.getWeChatQuery(key, "", "", "");
    call.enqueue(callback);
}

打印结果:
