Retrofit2+RxJava2遇到接口返回空数据Null的拦

OKHTTP3添加一个拦截器，碰到接口只返回code200的接口，添加一个NullResponseInterceptor拦截器，再次封装Response数据

okhttp初始化处添加拦截器

okhttpBuilder.addInterceptor(new NullResponseInterceptor());

拦截器NullResponseInterceptor的代码

/**

 * Retrofit2的2.0版本不支持解析OnNext的Null数据，拦截器做规范化返回数据
 */
public class NullResponseInterceptor implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {
        Response response = chain.proceed(chain.request());

        if (response.body().contentLength() == 0 && response.code() == 200) {
            MediaType mediaType = response.body().contentType();
            //*********添加自定义的解析基类*********
            BaseJson baseJson = new BaseJson();
            baseJson.code = 200;
            baseJson.message = "Success";
             //*********添加自定义的解析基类*********
            String baseJsonString = new Gson().toJson(baseJson);
            ResponseBody responseBody = ResponseBody.create(mediaType, baseJsonString);
            return response.newBuilder().body(responseBody).build();
        } else {
            return response;
        }
    }

}
