[英]How to write to a text file in a blob container using Azure function with python?
I am trying to run a timer trigger in Azure function which will write into my file saved in the blob storage container output
as log.txt
.我正在尝试在 Azure 函数中运行计时器触发器,该触发器将写入保存在 blob 存储容器output
中的我的文件中,输出为log.txt
。 Below is my init .py -下面是我的初始化.py -
import datetime
import logging
import azure.functions as func
def main(mytimer: func.TimerRequest, outputblob : func.Out[str]) -> None:
utc_timestamp = datetime.datetime.utcnow().replace(
tzinfo=datetime.timezone.utc).isoformat()
outputblob.set('some text')
if mytimer.past_due:
logging.info('The timer is past due!')
logging.info('Python timer trigger function ran at %s', utc_timestamp)
below are the bindings for function.json
-以下是function.json
的绑定 -
{
"scriptFile": "__init__.py",
"bindings": [
{
"name": "mytimer",
"type": "timerTrigger",
"direction": "in",
"schedule": "0 */5 * * * *"
},
{
"name": "outputblob",
"type": "blob",
"dataType": "string",
"path": "output/log.txt",
"connection": "AzureWebJobsStorage",
"direction": "out"
}
]
}
Also this is the output of the log stream which I checked today, maybe this could help这也是我今天检查的日志流的输出,也许这会有所帮助
The function is running but it is not writing anything to the log.txt
.该函数正在运行,但它没有向log.txt
写入任何内容。 I am a beginner in the azure functions, so please pardon silly mistakes.我是天蓝色函数的初学者,所以请原谅愚蠢的错误。
This was working fine after reproducing from our end.从我们的末端复制后,这工作正常。 Make sure you are adding the connection string of your storage account in local.settings.json.确保在 local.settings.json 中添加存储帐户的连接字符串。 Also the corn expression in your timer function 0 */5 * * * *
runs 12 times an hour which means for every 5 mins a trigger is going to occur.此外,计时器函数0 */5 * * * *
中的玉米表达式每小时运行 12 次,这意味着每 5 分钟就会发生一次触发器。 so make sure you wait until the function gets triggered.所以一定要等到函数被触发。
just to check if the result is getting reflected I have changed the corn expression to 5-7 * * * * *
which runs Three times a minute.只是为了检查结果是否得到反映,我已将玉米表达式更改为5-7 * * * * *
,它每分钟运行 3 次。
