OKHttp Authenticator 不适用于 Retrofit 暂停乐趣

Question

我最近将 Retrofit 更新为 2.7.0 并将 OKHttp 更新为 3.14.4 以利用 Retrofit 界面上的暂停乐趣。

除此之外，我还尝试为刷新令牌逻辑实现 Authenticator。

这是改装界面

interface OfficeApi {
    @Authenticated
    @POST
    suspend fun getCharacter(): Response<CharacterResponse>
}

这是我的身份验证器

class CharacterAuthenticator : Authenticator {

    override fun authenticate(
        route: Route?,
        response: Response
    ): Request? {
        if (responseCount(response) >= 2) return null

        return response.request()
                        .newBuilder()
                        .removeHeader("Authorization")
                        .addHeader("Authorization", "Bearer $newToken")
                        .build()

        return null
    }

    private fun responseCount(response: Response?): Int {
        var result = 1
        while (response?.priorResponse() != null) result++
        return result
    }

}

这是改装趣味电话

    override suspend fun getCharacter() = safeApiCall(moshiConverter) {
        myApi.getCharacter()
    }

这是safeApiCall:

suspend fun <T> safeApiCall(
    moshiConverter: MoshiConverter,
    apiCall: suspend () -> Response<T>
): Result<T?, ResultError.NetworkError> {
    return try {
        val response = apiCall()
        if (response.isSuccessful) Result.Success(response.body())
        else {
            val errorBody = response.errorBody()
            val errorBodyResponse = if (errorBody != null) {
                moshiConverter.fromJsonObject(errorBody.string(), ErrorBodyResponse::class.java)
            } else null

            Result.Error(
                ResultError.NetworkError(
                    httpCode = response.code(),
                    httpMessage = response.message(),
                    serverCode = errorBodyResponse?.code,
                    serverMessage = errorBodyResponse?.message
                )
            )
        }
    } catch (exception: Exception) {
        Result.Error(ResultError.NetworkError(-1, exception.message))
    }
}

身份验证器工作正常，尝试刷新令牌两次然后放弃。问题是：当它放弃时（return null），改造（safeApiCall 函数）的执行不会继续。通话成功与否，我没有任何反馈。

使用Authenticator和Coroutines有什么问题吗suspend fun？

Answer 1

删除暂停尝试以下代码

fun getCharacter(): Response<CharacterResponse>

Answer 2

这不是死循环吗？

while (response?.priorResponse() != null)

不应该吗

var curResponse: Response? = response
while (curResponse?.priorResponse() != null) {
    result++
    curResponse = curResponse.priorResponse()
}
