我已经查询了查询以获取所有事件数据实体列表。结果是谷歌数据存储中的这样。
[{
"key": {
"id": 5678669024460800,
"kind": "Event",
"path": [
"Event",
5678669024460800
]
},
"data": {
"createdAt": "2017-03-27T06:28:58.000Z",
"users":["test1@xxx.com","test2@xxx.com","test3@xxx.com"]
}
},
{
"key": {
"id": 5678669024460800,
"kind": "Event",
"path": [
"Event",
5678669024460800
]
},
"data": {
"createdAt": "2017-03-27T06:28:58.000Z",
"users":["test1@xxx.com"]
}
},
{
"key": {
"id": 5678669024460800,
"kind": "Event",
"path": [
"Event",
5678669024460800
]
},
"data": {
"createdAt": "2017-03-27T06:28:58.000Z",
"users":["test2@xxx.com","test3@xxx.com"]
}
}]
但我需要编写一个查询来过滤电子邮件ID。意味着我需要获取与电子邮件ID匹配的实体。例如,如果我将emailid传递为" test1@xxx.com" ,我应该得到这样的最终结果。任何人都可以帮助我。

答案 0 :(得分:3)
GQL查询类似于 -
SELECT * FROM Event WHERE users='test1@xxx.com'
您需要确保将users
属性编入索引才能使搜索生效,否则您可能无法获得任何结果。
