android - 如何使用 Authenticator 和挂起 api 功能？改造

Question

我正在建立客户:

OkHttpClient().newBuilder()
        .authenticator(object : Authenticator {
        override fun authenticate(route: Route?, response: Response): Request? {
            val request = AppPreferences.refreshToken?.let {
                api.refreshTokenC(it).execute()
            }
            
         ...
        })

为此，我使用通常的 fun 返回 Call :

@POST("Accounts/refresh")
fun refreshTokenC(@Query("refreshToken") refreshToken: String): Call<TokenResponse>

但是如何将它与挂起功能一起使用？:

    @POST("Accounts/refresh")
suspend fun refreshToken(@Query("refreshToken") refreshToken: String): Response<TokenResponse>

Answer 1

fun authenticate(route: Route?, response: Response)不是挂起函数，我们不能从中调用挂起函数。

可以使用runBlocking :

Runs a new coroutine and blocks the current thread interruptibly until its completion. This function should not be used from a coroutine. It is designed to bridge regular blocking code to libraries that are written in suspending style, to be used in main functions and in tests.

fun authenticate(route: Route?, response: Response)在后台线程上被调用，我们可以使用 runBlocking安全。

val request = AppPreferences.refreshToken?.let { token ->
    runBlocking { api.refreshToken(token) }
}

类似代码: AuthInterceptor.kt
