Question

官方文档似乎缺少使用这些输出绑定的文档，https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-java没有提供使用这些绑定的任何示例。

有没有人有运气使用这些？我希望实现类似的目标：

@FunctionName("consumeNodeInfo")
fun consumeNodeInfoFromQueue(@QueueTrigger(queueName = "nodeinfos", connection = "AzureWebJobsStorage", name = "nodeinfos", dataType = "binary") addedNodeInfo: ByteArray,
                             @TableOutput(name = "networkmap", tableName = "networkmap") table: OutputBinding<SignedNodeInfoRow>) {
    table.value = SignedNodeInfoRow(addedNodeInfo)
}

open class SignedNodeInfoRow(val signedNodeInfo: ByteArray) {
    val rowKey = signedNodeInfo.deserialize<SignedNodeInfo>().raw.hash
}

<强> @BlobOutput：

请参阅我的示例代码：

@FunctionName("blob")
public String functionHandler(
            @QueueTrigger(name = "myQueueItem", queueName = "walkthrough", connection = "AzureWebJobsStorage") String queue,
            @BlobOutput(name = "blob", connection = "AzureWebJobsStorage" , path = "samples-java/2.txt") OutputBinding<String> blob) {

        blob.setValue(queue);
        return queue;
}

AzureWebJobsStorage已在local.settings.json

中配置

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "<your connection string>",
    "AzureWebJobsDashboard": ""
  }
}

<强> function.json：

{
  "scriptFile" : "..\\fabrikam-functions-1.0-SNAPSHOT.jar",
  "entryPoint" : "com.fabrikam.functions.Function.functionHandler",
  "bindings" : [ {
    "type" : "queueTrigger",
    "name" : "myQueueItem",
    "direction" : "in",
    "connection" : "AzureWebJobsStorage",
    "queueName" : "walkthrough"
  }, {
    "type" : "blob",
    "name" : "blob",
    "direction" : "out",
    "connection" : "AzureWebJobsStorage",
    "path" : "samples-java/2.txt"
  } ],
  "disabled" : false
}

<强> @TableOutput：

仅供参考：

我们可以从doc检查function.json中的属性。永远不要忘记名为RowKey的房产。

示例代码：

@FunctionName("consumeNodeInfo")
fun consumeNodeInfoFromQueue(@QueueTrigger(queueName = "nodeinfos", connection = "AzureWebJobsStorage", name = "nodeinfos", dataType = "binary") addedNodeInfo: ByteArray,
                             @TableOutput(name = "networkmap", tableName = "networkmap", connection = "AzureWebJobsStorage", partitionKey = "nodeInfos") table: OutputBinding<SignedNodeInfoRow>) {
    val nodeInfo = addedNodeInfo.deserialize<SignedNodeInfo>()
    table.value = SignedNodeInfoRow(nodeInfo.raw.hash.toString(), addedNodeInfo.toBase58())
}

data class SignedNodeInfoRow(val RowKey: String, val arrayAsBase58String: String)

希望它对你有所帮助。

经过大量调查后发现，你必须拥有一个名为“RowKey”的属性

大写R 非常重要 以下是工作实现的示例。

@FunctionName("consumeNodeInfo")
fun consumeNodeInfoFromQueue(@QueueTrigger(queueName = "nodeinfos", connection = "AzureWebJobsStorage", name = "nodeinfos", dataType = "binary") addedNodeInfo: ByteArray,
                             @TableOutput(name = "networkmap", tableName = "networkmap", connection = "AzureWebJobsStorage", partitionKey = "nodeInfos") table: OutputBinding<SignedNodeInfoRow>) {
    val nodeInfo = addedNodeInfo.deserialize<SignedNodeInfo>()
    table.value = SignedNodeInfoRow(nodeInfo.raw.hash.toString(), addedNodeInfo.toBase58())
}

data class SignedNodeInfoRow(val RowKey: String, val arrayAsBase58String: String)

如何在java azure函数中使用@BlobOutput或@TableOutput
