firebase-Firestore REST API开始查询

Question

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

{
    "error": {
        "code": 400,
        "message": "Invalid JSON payload received. Unknown name \"structured_query\" at 'document': Cannot find field.",
        "status": "INVALID_ARGUMENT",
        "details": [
            {
                "@type": "type.googleapis.com/google.rpc.BadRequest",
                "fieldViolations": [
                    {
                        "field": "document",
                        "description": "Invalid JSON payload received. Unknown name \"structured_query\" at 'document': Cannot find field."
                    }
                ]
            }
        ]
    }
}

有人可以告诉我我在做什么错吗？非常感谢。我被卡住了，无法继续。

在你的 URL 中去掉用户。

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