OkHttp3在拦截器中动态改变schema,host等

最近在写wanandroid app,之前登录和注册接口是http请求,今天登录app发现无法登录了.

去www.wanandroid.com看了下,原来是鸿洋大神登录和注册接口改成了https了,
那么怎么优雅处理这个问题呢

当然是在拦截器中处理了

这是登录和注册接口

  /**
     * 登陆
     * http://www.wanandroid.com/user/login
     *
     * @param username user name
     * @param password password
     * @return 登陆数据
     */
    @POST("user/login")
    @FormUrlEncoded
    Observable> getLoginData(@Field("username") String username, @Field("password") String password);

    /**
     * 注册
     * http://www.wanandroid.com/user/register
     *
     * @param username user name
     * @param password password
     * @param repassword re password
     * @return 注册数据
     */
    @POST("user/register")
    @FormUrlEncoded
    Observable> getRegisterData(@Field("username") String username, @Field("password") String password, @Field("repassword") String repassword);

处理之后是这个样子滴

   OkHttpClient provideClient(OkHttpClient.Builder builder) {
        if (BuildConfig.DEBUG) {
            HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
            loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
            builder.addInterceptor(loggingInterceptor);
            builder.addNetworkInterceptor(new StethoInterceptor());
        }
        File  cacheFile = new File(Constants.PATH_CACHE);
        Cache cache     = new Cache(cacheFile, 1024 * 1024 * 50);
        Interceptor cacheInterceptor = chain -> {
            Request request = chain.request();
            if (!CommonUtils.isNetworkConnected()) {
                request = request.newBuilder()
                                 .cacheControl(CacheControl.FORCE_CACHE)
                                 .build();
            }
          //看这里,开始处理了
          //处理的当url是login或者regist接口时,将schema设置成https
            String url = request.url().toString();
            if (url.endsWith("user/login") || url.endsWith("user/register")) {
                HttpUrl httpUrl = request.url()
                                         .newBuilder()
                                         .scheme("https")
                                         .host("www.wanandroid.com")
                                         .build();
                request = request.newBuilder()
                                 .url(httpUrl)
                                 .build();
            }
            //处理结束了,完美搞定
            Response response = chain.proceed(request);
            if (CommonUtils.isNetworkConnected()) {
                int maxAge = 0;
                // 有网络时, 不缓存, 最大保存时长为0
                response.newBuilder()
