小编Mys*_*que的帖子

您好，我是firestore的新手，我正尝试使用rest API从名为“用户”的集合中查询，查找所有具有名为test2的字段的用户

这是我的POST请求：

https://firestore.googleapis.com/v1beta1/projects/ {myprojectid} / databases /（默认）/ documents / Users：runQuery

身体：

{
"structuredQuery": {
    "where" : {
        "fieldFilter" : { 
        "field": {"fieldPath": "about"}, 
        "op":"EQUAL", 
        "value": {"string": "test2"}
        }
    },
    "from": [{"collectionId": "Users"}]
    }
}

我得到回应

                        "description": "Invalid JSON payload received. Unknown name \"structured_query\" at 'document': Cannot find field."
                    } …
