我正在尝试将由Blob存储触发的Azure函数“退出”到Cosmos db。但是Cosmos db是否具有Cassandra Api或连接字符串？ 我需要SQL api吗？
function.json
{ "scriptFile": "__init__.py", "bindings": [
{
"name": "inputBlob",
"type": "blobTrigger",
"direction": "in",
"path": "myblobcontainer/input/{name}",
"connection": "AzureWebJobsStorage"
},
{
"direction": "out",
"type": "cosmosDB",
"name": "$return",
"databaseName": "solar_system",
"collectionName": "mercury",
"leaseCollectionName": "leases",
"createLeaseCollectionIfNotExists": true,
"connectionStringSetting": "AzureWebJobsDocumentDBConnectionString",
"createIfNotExists": false
} ] }
初始化 .py
import logging
import azure.functions as func
import json
def main(inputBlob: func.InputStream) -> func.Document:
logging.info(f"Blob trigger executed with cosmo {inputBlob.name} >>>")
logging.info(f"Blob Name: {inputBlob.name} ({inputBlob.length}) bytes")
logging.info(f"Full Blob URI: {inputBlob.uri}")
# for testing purpose, the below data dictonary is inserted.
newdoc_dict = {
"area":1234,
"name":"mmmmm",
"tim":1234567890,
"info":"bbbb"
}
newdocs = (func.Document.from_dict(newdoc_dict))
return newdocs
在
“ connectionStringSetting”：“ AzureWebJobsDocumentDBConnectionString”
，AzureWebJobsDocumentDBConnectionString设置为我的cosmos db cassandra API
