Retrofit: I want to use Tag annotation to pass some data in the request, and then I would like to intercept that data from the interceptor.
Something like this
How can I use it something like this, but without using Call
@Target(AnnotationTarget.VALUE_PARAMETER,
AnnotationTarget.FUNCTION
)
@Retention(AnnotationRetention.RUNTIME)
annotation class Tagz
@GET
suspend fun getUsers(@Tagz value: CachePolicy.Type, @Url placeholder: String): Response<UserEntity?>
Using the above is throwing me this:
java.lang.IllegalArgumentException: No Retrofit annotation found. (parameter #1)
How can I pass my value in the parameter as a tag in the request?
BTW: I was able to use tag like this
@Target(AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER)
@Retention(AnnotationRetention.RUNTIME)
annotation class CachePolicyTag(val value: CachePolicy.Type)
@GET
@CachePolicyTag(CachePolicy.Type.DefaultCache)
suspend fun getUsers(@Url placeholder: String): Response<UserEntity?>
But instead of an annotation function, I want it to pass as a parameter in this suspend function.
I used retrofit @TAG to pass tag value and intercepted in the okhttp interceptor.
@GET
suspend fun getUsers(@Tag cacheType: CachePolicy.Type, @Url placeholder: String): Response<UserEntity?>
and in my Okhttp interceptor
override fun intercept(chain: Interceptor.Chain): Response {
val request = chain.request()
val response = chain.proceed(request)
request.tag(Invocation::class.java)?.let {
kotlin.runCatching {
val cachePolicyType = it.arguments()[0] as CachePolicy.Type
}
}
return response
}
In case of any errors or class cast exception, it won't throw any exception out side of the runCatching block as well.
