我有一个返回包装结果的 API，我想制作一个通用包装器而不是 20 个。

但是，我无法将结果值转换为我的泛型类型。这是代码：

来自 api 的响应：

override fun onResponse(call: Call, response: Response) {

        val userResponse = response.getResultAs<UserResponse>()

        userResponse?.let { user ->
            App.shared.userSettings.edit().putString(UserSettingsKeys.ACTIVE_USER.key,
                    ObjectMapper().writeValueAsString(user)).apply()
            App.shared.userSettings.edit().putString(UserSettingsKeys.TOKEN.key,
                    response.header("Authorization")).apply()
            presenter?.onLoginSuccess(user)
        } ?: presenter?.onLoginFailure("No response returned")
}

结果类的扩展：

fun <T> Response.getResultAs(): T? {

    this.body()?.string()?.let {
        val mapper = jacksonObjectMapper()
        val obj = JsonParser().parse(it).asJsonObject.toString()
        val baseResponseWrapper: BaseResponseWrapper<T> = mapper.readValue(obj)

        when {
            baseResponseWrapper.errorValues != null -> {
                baseResponseWrapper.logErrorMessage = "invalid credentials"
            }

            baseResponseWrapper.returnVal == null -> {
                baseResponseWrapper.logErrorMessage = "returnVal could not be parsed"
            }

            else -> {
                return baseResponseWrapper.returnVal
            }
        }
    }
    return null
}

响应包装类：

data class BaseResponseWrapper<T>(

    @field:JsonProperty("returnVal")
    val returnVal: T? = null,

    @field:JsonProperty("errorDescription")
    val errorDescription: String? = null,

    @field:JsonProperty("errorCode")
    val errorCode: Int? = null,

    @field:JsonProperty("errorValues")
    val errorValues: Any? = null,

    var logErrorMessage: String? = null

)

它将数据解析为格式正确的链接哈希映射，而不是我的类。这是我在调试崩溃之前的状态：

baseResponseWrapper.returnVal = {LinkedHashMap@7400}  size = 9  
0 = {LinkedHashMap$LinkedHashMapEntry@7409} "isInfluencer" -> "false"  
1 = {LinkedHashMap$LinkedHashMapEntry@7410} "currentUserBranchUsername" -> "000"  
2 = {LinkedHashMap$LinkedHashMapEntry@7411} "parentUser" -> " size = 4"  
3 = {LinkedHashMap$LinkedHashMapEntry@7412} "profile" -> " size = 3"  
4 = {LinkedHashMap$LinkedHashMapEntry@7413} "currentUserProfile" -> "null"  
5 = {LinkedHashMap$LinkedHashMapEntry@7414} "email" -> "null"  
6 = {LinkedHashMap$LinkedHashMapEntry@7415} "userName" -> "null"  
7 = {LinkedHashMap$LinkedHashMapEntry@7416} "muviId" -> "null"  
8 = {LinkedHashMap$LinkedHashMapEntry@7417} "userId" -> "0000-0000-0000"

这是我的控制台错误：

2018-10-29 12:56:15.401 1916-1962/com.appshack.livetree E/AndroidRuntime：致命异常：OkHttp 调度程序进程：com.appshack.livetree，PID：1916 java.lang.IllegalStateException：在 okio.RealBufferedSource 关闭.rangeEquals(RealBufferedSource.java:408) at okio.RealBufferedSource.rangeEquals(RealBufferedSource.java:402) at okhttp3.internal.Util.bomAwareCharset(Util.java:469) at okhttp3.ResponseBody.string(ResponseBody.java:175)在 com.appshack.livetree.utililty.extensions.OkHttpResult_getResultAsKt.getResultAs(OkHttpResult+getResultAs.kt:17) 在 com.appshack.livetree.ui.outside.login.LoginInteractor$loginResponseCallback$1.onResponse(LoginInteractor.kt:43) 在okhttp3.internal.NamedRunnable 处的 okhttp3.RealCall$AsyncCall.execute(RealCall.java:153)。在 java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1133) 在 java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:607) 在 java.lang.Thread 运行(NamedRunnable.java:32) .run(Thread.java:761)

我是泛型新手，但有什么办法可以使这项工作？
