Question

帖子似乎很长，但仅仅是因为数据（样本和错误）。

我正在尝试使用cep 2.1.0模拟buildFailed示例。（此示例有效）。

我创建了自己的流和我自己的示例数据。

然而它接触到了cep的输入处理程序，他的事件出了问题。

到目前为止，我还没有找到问题。

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"
        }
    ]
}

事件数据：

[
{
 "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"] 
 }
]

当我发送streamdef时，除了admin连接之外没有错误和没有日志我们可能需要更多反馈。我使用curl post命令。

当我发送事件时，我有错误：

请有人，你有任何提示吗？我真的需要这个继续我的概念证明CEP项目。

祝你好运，西里尔

我已经详细介绍了您在上面提供的详细信息...但是如果没有存储桶配置和完整的错误日志，很难说出现了什么问题...但我已经检查了您上面给出的流定义和事件...它完美无缺地工作......我希望你在创建存储桶时可能会犯一个简单的错误...这里我正在共享我创建的存储桶xml（注意：更改输出主题中的电子邮件地址）

事件json：link [1]

stream json：link [2]

bucket xml：link [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

事件的curl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
