Azure功能状态代码500内部服务器错误 [英] Azure Function Status Code 500 internal server error
问题描述
我有一个逻辑应用程序,它将azure函数用作http触发器并获取返回字符串.当azure函数要接收Base64字符串,使用信息创建文件并上载到分配的存储帐户时,每次运行它时,我都会不断从Azure函数中获取状态代码500内部服务器错误.经过多次尝试和错误,我推断出问题发生在从Base64字符串创建文件以及创建Blob容器客户端的时候.
I have a logic app that uses azure function as a http trigger and gets a return string. When the azure function is to receive a Base64 string, create a file with the information and uploads to the assigned storage account, I keep getting status code 500 internal server error from the Azure function every time I run it. After many trial and error I deduced the problem occurs from when the file is to be created from the Base64 string and when the blob container client is created.
所以请帮助我.
更新:根据您的一些建议,我对应用程序的见解进行了几次运行,并两次出现此错误:
UPDATE: As per some of your suggestions, I implemented application insights ran it a few times and got this error occuring twice:

推荐答案
您正在尝试写入"D"磁盘.由于Azure功能无法直接访问磁盘,因此在尝试写入不存在的磁盘时会出现500错误.
You are trying to write to the "D" disk. Since the Azure function does not have direct access to disks, you get a 500 error when trying to write to a disk that does not exist.
要从Azure函数写入文件,可以使用Azure存储SDK.
To write to a file from an Azure function you can use the Azure Storage SDK.
