当使用具有blob存储输出绑定的azure函数时,如何获取创建的blob的名称,路径或URL?我想保存它后将其保存到数据库中。
我正在使用Python,但任何一个例子都可以:
blob = open(os.environ['outputBlob'], 'wb')
blob.write(attachment.get_payload(decode=True))
print blob.name # this is not the correct name, but actually the temp file name I think
blob.close()

对于C#: 正如在https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob#input中所讨论的,您可以使用以下类型的blob绑定
下面是绑定json文件和代码的示例。我在http返回中返回outpuBlob.Uri以获取Blob的主要位置路径。
绑定: -
{
"bindings": [
{
"authLevel": "function",
"name": "req",
"type": "httpTrigger",
"direction": "in",
"methods": [
"get",
"post"
]
},
{
"name": "$return",
"type": "http",
"direction": "out"
},
{
"type": "blob",
"name": "outputBlob",
"path": "outcontainer/{rand-guid}",
"connection": "AzureWebJobsDashboard",
"direction": "inout"
}
],
"disabled": false
}
功能代码(C#):
#r "Microsoft.WindowsAzure.Storage"
using System.Net;
using Microsoft.WindowsAzure.Storage.Blob;
public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log,CloudBlockBlob outputBlob)
{
log.Info("C# HTTP trigger function processed a request.");
// parse query parameter
string name = req.GetQueryNameValuePairs()
.FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
.Value;
if (name == null)
{
// Get request body
dynamic data = await req.Content.ReadAsAsync<object>();
name = data?.name;
}
return name == null
? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
: req.CreateResponse(HttpStatusCode.OK, "Hello " + outputBlob.Uri);
}

查看Python脚本的处理空间中的环境变量。你应该有一个包含blob绑定路径的文件。
