flutter - Dio retrofit 子库的Flutter缓存机制

我的应用程序使用的是DioRetrofit子库,在其中我不确定如何为它定义缓存机制,
我在Retrofit示例代码中找到了这一行:

@GET("")
Future<String> testCustomOptions(@DioOptions() Options options);
现在如何在此 http请求上定义缓存?
Retrofit文档:
void main(List<String> args) {
final dio = Dio(); // Provide a dio instance
dio.options.headers["Demo-Header"] = "demo header"; // config your dio headers globally
final client = RestClient(dio);

client.getTasks().then((it) => logger.i(it));
dio-http-cache文档:
QuickStart

Add a dio-http-cache interceptor in Dio :

dio.interceptors.add(DioCacheManager(CacheConfig(baseUrl: "http://www.google.com")).interceptor);

Set maxAge for a request :

Dio().get(
"http://www.google.com",
options: buildCacheOptions(Duration(days: 7)),
);
我完整的实现代码:
Provider(
create: (_) => MyApis.create(),
),


abstract class MyApis{
factory MyApis(Dio dio, {String baseUrl}) = _MyApis;

@GET("/login")
Future<HttpResponse<PageInformation>> login(@DioOptions() Options options);

static MyApis create() {
final dio = Dio();
dio.options.headers['Content-Type'] = 'application/json';
dio.options.receiveTimeout = 60000;
dio.options.connectTimeout = 120000;
return _MyApis(dio);
}
}

最佳答案

在API添加点调用中添加参数

Future<HttpResponse<PageInformation>> login(@DioOptions() Options options);
在Dio中添加拦截器
dio.interceptors.add(DioCacheManager(CacheConfig(baseUrl: 'YOUR BASE URL')).interceptor);
为Endpoint参数创建一个对象
Options options = buildCacheOptions(Duration(days: 10),forceRefresh: true);
调用您的API端点
myapi.login(options)
