在Azure函数中使用Python文件-只读文件系统 [英] Working with Python Files in Azure Function - Read Only File System

问题描述

Azure函数的新功能，但希望利用ADF管道中的Function来调用第三方并写回json以进行提取.

New to Azure functions, but looking to utilize a Function in an ADF pipeline to call out to a third party and write the json back for ingestion.

但是，我收到结果:失败异常:OSError:[Errno 30]只读文件系统:..."/home/site/wwwroot/AzureFunctionFileTest/init.py"，第10行，主要带有open('test.json'，'w')作为文件.

However, I receive Result: Failure Exception: OSError: [Errno 30] Read-only file system: ... "/home/site/wwwroot/AzureFunctionFileTest/init.py", line 10, in main with open('test.json', 'w') as file.

我的脚本在下面:

logging.info('Python HTTP trigger function processed a request.')

logging.info('opening file')

with open('test.json', 'rb') as file:
    logging.info('creating data')
    data = "Hello world"
    logging.info('writing file')
    file.write(data)

return func.HttpResponse(f"This HTTP triggered function executed successfully with {data}.")

是否缺少我想要的Azure Function配置?

Is there an Azure Function config that I'm missing?

推荐答案

当前目录确实是只读的.将/tmp 用于临时文件(例如， open('/tmp/test.json'，...).有关更多详细信息，请参见

The current directory is indeed read-only. Use /tmp for temporary files (for example, open('/tmp/test.json', ...). For more details, see https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-python#temporary-files.
