使用 Invoke-RestMethod post 到 cosmosDB Returns a 400

Question

我正在尝试 post 使用 powershell 将文档发送到 cosmosdb，我已按照此 post https://www.systemcenterautomation.com/2018/06/cosmos-db-rest-api-powershell/ 中的步骤进行操作，但每次仍然收到 400 错误

$SomeObject = [PSObject]@{ id = 1 ; Application = "Ops"; Environment = "Dev"; adKey = "555-555-5555"; } 
Post-CosmosDocuments -EndPoint $CosmosDBEndPoint -MasterKey $MasterKey -DBName $DBName -CollectionName $CollectionName -JSON ($SomeObject | ConvertTo-Json)

returns每次都是400，不知道请求有什么问题。

Answer 1

根据 Powershell script samples，我发现您缺少 headers：

x-ms-documentdb-partitionkey
User-Agent
2018-12-31 为 x-ms-version

添加您收到的回复 body 也会有所帮助。

Answer 2

它正在工作

我不确定为什么我得到了 400。也许我创建 collection 的时间不对。

使用 Invoke-RestMethod post 到 cosmosDB Returns a 400
