如何将 JSON 导入 Cosmos DB

Question

我有一个包含多个数据库的现有 CouchDB 实例。使用 Postman，我将 10 个文档导出到一个 .json 文件。使用 DocumentDB 数据迁移工具，我能够将此文件的内容导入 Cosmos。

但是，我似乎有效地导入了一个文档。 Azure 数据资源管理器表明我的“集合”中有一个文档。

在 CouchDB 中，最高级别的 Identifier 是 doc._id。我尝试将“doc._id”、“id”和“_id”指定为我的 ID 字段，但均无济于事。我究竟做错了什么？如何分别导入每个 JSON 文档？

Answer 1

我使用 DocumentDB 数据迁移工具导入了一个包含 4 个文档的 .json 文件，它对我来说效果很好。

我的.json 文件：

[
    {
        "name":"jay1",
        "age":20
    },
    {
        "name":"jay2",
        "age":20
    },
    {
        "name":"jay3",
        "age":20
    },
    {
        "name":"jay4",
        "age":20
    }
]

文档分别导入到集合中。

JSON 文件源导入器选项允许您导入一个或多个 单个文档 JSON 文件或 JSON 文件，每个文件都包含一个数组 JSON 文档。添加包含要导入的 JSON 文件的文件夹时， 您可以选择递归搜索子文件夹中的文件。

您可以检查您是否遵循official tutorial 中所述的上述规则来创建您的 .json 文件。 （例如，您的文档是否在数组中？）

希望对你有帮助。

更新答案：

我厌倦了将遵循您在回复中提到的格式的数据导入cosmos db。

我的更新.json文件：

[
    {
        "id":"001",
        "name":"jay1",
        "age":20,
        "array": {
            "a":1,
            "b":2,
            "c":{
                "d":3,
                "e": {
                    "f":4
                }
            }
        }
    },
    {
        "id":"002",
        "name":"jay2",
        "age":20,
        "array": {
            "a":1,
            "b":2,
            "c":{
                "d":3,
                "e": {
                    "f":4
                }
            }
        }
    },
    {
        "id":"003",
        "name":"jay3",
        "age":20,
        "array": {
            "a":1,
            "b":2,
            "c":{
                "d":3,
                "e": {
                    "f":4
                }
            }
        }
    }
]

文档成功导入集合。

更新答案 2：

我按照您提供的文档格式在我的 .json 文件中创建了 3 个示例文档。（我只是将“_id”属性更新为“testX”）

我的.json 文件：

文档已导入数据库，没有发生错误。

如果你我之间有什么不同，请告诉我。

Answer 2

另一个答案是大约一年前，它使用dtui.exe。

dtui.exe 是一个 GUI 工具
dt.exe 是一个命令行工具

即日起可从https://www.microsoft.com/en-us/download/details.aspx?id=46436下载两者

以下解决方案使用 dt.exe（自动化您的流程，以便将来可以重复且不会出现问题）

`"C:\path-to-your-dt-exe\dt.exe"  /s:JsonFile   /s.Files:"C:\path-to-your-json-files-of-one-collection-only\*.json"   /t:DocumentDB    /t.ConnectionString:"AccountEndpoint=https://localhost:8081/;AccountKey=<big account key here>;Database=<your db name here>"   /t.Collection:<your collection name here>   /t.PartitionKey:<your partition key here>   /t.CollectionThroughput:2500`

注意
- 上面的数据库（<your db name here>）和集合（<your collection name here>），必须已经存在
- 将<...> 替换为上面的数据，然后在cmd 中运行。
- /s是源，/t是目标，这里源是JSON文件，目标是本地documentBD

希望对您有所帮助。
