android - Volley Kotlin 协程抛出 CompilationException

我需要使用 Volley 从 API 检索各种 JSONObject。 API 需要使用 Basic 进行 header 身份验证。如果我不添加 header ，它会起作用，但当我添加 header 时，我会不断收到 org.jetbrains.kotlin.codegen.CompilationException 。以下是我编写的函数:

private suspend fun readData(url: String): JSONObject = suspendCancellableCoroutine { continuation ->
    val request: JsonObjectRequest = object: JsonObjectRequest(Request.Method.POST, url, null, Response.Listener<JSONObject> {
        continuation.resume(it)
    }, Response.ErrorListener {
        continuation.resumeWithException(Exception(it.cause))
    }) {
        override fun getHeaders(): Map<String, String> = mapOf("Content-Type" to "application/json", "charset" to "utf-8", "Authorization" to "Basic ".plus(android.util.Base64.encode(String.format("%s:%s", getString(R.string.api_login_username), getString(R.string.api_login_password)).toByteArray(), android.util.Base64.DEFAULT)))
    }
    request.setShouldCache(false)
    this.queue?.add(request)
}


fun data(url: String) = async(CommonPool) { readData(url) }

他们像这样实现它们:

val brands = data(getString(R.string.api_url).plus("/api/brand"))
val models = data(getString(R.string.api_url).plus("/api/model"))

launch(UI) {
    val brandsJsonArray = brands.await().getJSONArray("recordset")
    val modelsJsonArray = models.await().getJSONArray("recordset")
}

但这是我尝试编译项目时不断遇到的异常:

org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't inline method call 'suspendCoroutine' into
    public final suspend fun readData(queue: com.android.volley.RequestQueue?, url: kotlin.String, continuation: kotlin.coroutines.experimental.Continuation<org.json.JSONObject>): kotlin.Any? defined in com.universales.inspeccion.activities.InspectionCreateActivity
    suspend fun readData(url: String): JSONObject = suspendCancellableCoroutine { continuation ->
            val request = object : JsonObjectRequest(Request.Method.GET, url, JSONObject(), Response.Listener {
                continuation.resume(it)
            }, Response.ErrorListener {
                continuation.resumeWithException(Exception(it.cause))
            }) {
                override fun getHeaders(): Map<String, String> = mapOf("Content-Type" to "application/json", "charset" to "utf-8", "Authorization" to "Basic ".plus(android.util.Base64.encode(String.format("%s:%s", getString(R.string.api_login_username), getString(R.string.api_login_password)).toByteArray(), android.util.Base64.DEFAULT)))
            }
            queue?.add(request)
            continuation.invokeOnCompletion {
                request.cancel()
            }

最佳答案

将对象:JsonObjectRequest的定义推送到一个命名类，该类将延续作为构造函数参数。这样，您就可以使 suspendCancellableCoroutine 内的代码更简单，并避免此编译器错误。

suspend fun readData(url: String): JSONObject = suspendCancellableCoroutine { continuation ->
    RequestWithHeaders(url, continuation).also {
        it.setShouldCache(false)
        queue.add(it)
    }
}

class RequestWithHeaders(
        url: String,
        continuation: Continuation<JSONObject>
) : JsonObjectRequest(Request.Method.POST, url, null, Response.Listener {
    continuation.resume(it)
}, Response.ErrorListener {
    continuation.resumeWithException(Exception(it.cause))
}) {
    override fun getHeaders(): Map<String, String> = mapOf(
            "Content-Type" to "application/json; charset=utf-8",
            "Authorization" to "Basic")
}
