Google AnalyticsAPI文档显示,为获取生命周期值,不应指定日期范围。但是当我提出这样的请求(没有日期范围)时,它会返回空维度和度量结果。但是当我使用日期范围时,它会返回该日期范围的维度和指标值。
以下摘自API documentation:
不应为群组或生命周期值指定日期范围 请求。
例如,如果我发出没有日期范围的请求,如下所示:
{
"reportRequests": [
{
"viewId": "XXXXXXXXX",
"dimensions": [
{
"name": "ga:date"
},
{
"name": "ga:eventLabel"
}
],
"metrics": [
{
"expression": "ga:totalEvents"
}
]
}
]
}
我收到以下回复:
{
"reports": [
{
"columnHeader": {
"dimensions": [
"ga:date",
"ga:eventLabel"
],
"metricHeader": {
"metricHeaderEntries": [
{
"name": "ga:totalEvents",
"type": "INTEGER"
}
]
}
},
"data": {
"totals": [
{
"values": [
"0"
]
}
]
}
}
]
}
但是,如果我包含日期范围,
{
"reportRequests": [
{
"viewId": "XXXXXXXX",
"dimensions": [
{
"name": "ga:date"
},
{
"name": "ga:eventLabel"
}
],
"metrics": [
{
"expression": "ga:totalEvents"
}
],
"dateRanges": [
{
"startDate": "2016-01-01",
"endDate": "2016-04-30"
}
]
}
]
}
我收到以下回复:
{
"reports": [
{
"columnHeader": {
"dimensions": [
"ga:date",
"ga:eventLabel"
],
"metricHeader": {
"metricHeaderEntries": [
{
"name": "ga:totalEvents",
"type": "INTEGER"
}
]
}
},
"data": {
"rows": [
{
"dimensions": [
"20160412",
"http://mytestblog.com/"
],
"metrics": [
{
"values": [
"1"
]
}
]
},
{
"dimensions": [
"20160412",
"http://mytestblog.com/2016/04/first-post.html"
],
"metrics": [
{
"values": [
"3"
]
}
]
},
{
"dimensions": [
"20160419",
"http://mytestblog.com/"
],
"metrics": [
{
"values": [
"4"
]
}
]
},
{
"dimensions": [
"20160419",
"http://mytestblog.com/2016/04/fourth.html"
],
"metrics": [
{
"values": [
"13"
]
}
]
}
],
"totals": [
{
"values": [
"21"
]
}
],
"rowCount": 4,
"minimums": [
{
"values": [
"1"
]
}
],
"maximums": [
{
"values": [
"13"
]
}
]
}
}
]
}
为什么即使在文档中指定,我还必须在ReportRequest中指定日期范围才能获取值?我在这里误解了终身价值的含义吗?
答案 0 :(得分:0)
reportRequest
对象应具有dateRanges
的值或cohortGroup
的定义值。如果省略这两个请求,则会假定startDate
7daysAgo
和endDate
yesterday
的默认值。
对文档的正确解释是,reportRequest
不应为群组和LTV请求定义dateRange
。但是,为了进行同类群组或生命周期值请求,您必须添加同类群组定义。对于终身价值请求,除dateRange
字段设置为 true 外,群组定义应具有特定lifetimeValue
