使用dagger Handle作为依赖注入来处理多个改装客户端？
使用dagger Handle作为依赖注入来处理多个改装客户端？
提问于 2021-08-05 12:23:18
我想在我的android应用程序中使用两个不同的后端与不同的响应格式，我正在使用句柄作为依赖注入与网络调用的改进，这是很好的工作。
因为我已经添加了我的第二个服务器网络文件和应用程序模块，它给我的错误在末尾列出。
在这种情况下，我需要知道如何在不做任何显著的架构更改的情况下解决问题。

如果您想使用Dagger或Hilt返回Retrofit client，那么您应该使用@Named注释。此注释帮助Hilt或Dagger理解具有相同Retrofit返回类型的您，您需要获取哪个Retrofit实例。
按照下面的方法，您可以提供多个带柄或短剑的改装实例。
首先，我在这里看到您提供了2个改造实例。为您提供的每个改造实例放置@Named注释。
object AppModule {
@Singleton
@Provides
@Named("Normal")
fun provideRetrofit(gson: Gson, @ApplicationContext appContext: Context): Retrofit = ...
@Singleton
@Provides
@Named("Email")
fun provideRetrofitEmall(gson: Gson, @ApplicationContext appContext: Context): Retrofit = ...
}接下来，当您提供api服务时，向Hilt或Dagger指定它需要哪个改装实例。
object AppModule {
@Provides
fun providePostsService(@Named("Normal") retrofit: Retrofit): ApiService = retrofit.create(ApiService::class.java)
@Provides
fun providePostsServiceEmall(@Named("Email") retrofit: Retrofit): EmallApiService = retrofit.create(EmallApiService::class.java)
}最后，清理项目并重新构建项目以查看结果。
