事件列表中的wso2 CEP錯誤

Question

該帖子似乎很長，但僅是因為數據（示例和錯誤）。

我正在嘗試制作一個桶來模擬cep 2.1.0中的buildFailed示例。 （此示例有效）。

我創建了自己的流和示例數據。

然而，這似乎暗示了輸入處理程序cep在我的事件中遇到了麻煩。

到目前為止，我還沒有發現問題。

流def：

    {
    "name":"eu.ima.event.stream",
    "version": "1.2.0",
    "nickName": "poc sample",
    "description": "poc sample stream",
    "metaData":[
    {
        "name":"host",
        "type":"string"
    }
    ], 
   "correlationData":[
    {
        "name":"processus",
        "type":"string"
    },
    {
        "name":"flux",
        "type":"string"
    },
    {   
        "name":"reference",
        "type":"string"
    }
    ],   
 "payloadData":[
        {
                "name":"timestamp",
                "type":"string"
        },
        {       "name":"code",
                "type":"string"
        },
        {
                "name":"category",
                "type":"string"
        },
        {
                "name":"msg",
                "type":"string"
        }
    ]
}

事件數據：

[
{
 "metaData" : ["192.168.1.2"] , 
 "correlationData" : ["PSOR", "Appli2", "Ref-1"] , 
 "payloadData" : ["1363700128138496600", "6", "BIZ", "6"] 
 }
 ,
{
 "metaData" : ["192.168.1.2"] , 
 "correlationData" : ["PSOR", "Appli2", "Ref-0"] , 
 "payloadData" : ["1363700126353394500", "6", "BIZ", "6"] 
 }
 ,
{
 "metaData" : ["192.168.1.2"] , 
 "correlationData" : ["PSOR", "Appli2", "Ref-3"] , 
 "payloadData" : ["1363700131731702100", "6", "BIZ", "6"] 
 }
 ,
{
 "metaData" : ["192.168.1.2"] , 
 "correlationData" : ["PSOR", "Appli2", "Ref-2"] , 
 "payloadData" : ["1363700129894597000", "6", "BIZ", "6"] 
 }
 ,
{
 "metaData" : ["192.168.1.2"] , 
 "correlationData" : ["PSOR", "Appli2", "Ref-4"] , 
 "payloadData" : ["1363700133472801700", "6", "BIZ", "6"] 
 }
]

當我發送streamdef時，除了已連接的管理員外，沒有錯誤，也沒有日志。我們可能需要更多反饋。 我使用curl post命令。

發送事件時出現錯誤：

請任何人，您有什么提示嗎？ 我真的需要這個，以繼續進行我的概念證明CEP項目。

最好的問候，西里爾

我已經仔細閱讀了上面給出的詳細信息...但是沒有存儲桶配置和完整的錯誤日志，很難說出問題所在...但是我已經檢查了上面給出的流定義和事件...它運行正常，沒有任何問題...希望您在創建存儲桶時可能犯了簡單的錯誤...在這里，我將共享我創建的存儲桶xml（請注意：更改輸出主題中的電子郵件地址）

事件json：鏈接[1]

流json：鏈接[2]

桶xml：鏈接[3]

Stream的curl命令：

curl -k --user admin:admin https://localhost:9443/datareceiver/1.0.0/streams/ --data @streamdefn2.json -H "Accept: application/json" -H "Content-type: application/json" -X POST

curl事件的命令：

curl -k --user admin:admin https://localhost:9443/datareceiver/1.0.0/stream/eu.ima.event.stream/1.2.0/ --data @events2.json -H "Accept: application/json" -H "Content-type: application/json" -X POST
