Using SFTP File Content in Azure Logic Apps - azure-logic-apps

Question

I have to pass File Name and File content to Azure function when new file is added or modified in SFTP folder. I am able to pass them but File content is getting passed as complex type json as follows:
{
"fileContent": {
"$content-type": "application/octet-stream",
"$content": "QWxvZnQgQidoYW0gU29obyBTcSAgICAg=="
},
"fileName": "testFile"
}
I just need to pass $content to Azure Function. My current code is as follows in logic app
"body": {
"fileContent": "#triggerBody()",
"fileName": "#triggerOutputs()['headers']['x-ms-file-name']"
},
How could I pass only content form FileContent to Azure function?

Answer 1

You should be able to just pass the content as-is. Logic Apps would decode the data and pass it as binary to the azure function (assuming the function can accept the binary content). You can pass the file name as a header.
If you want to attach the content as a property on a object, then you can use
"body": {
"fileContent": "#base64(triggerBody())",
"fileName": "#triggerOutputs()['headers']['x-ms-file-name']"
}

Answer 2

As you can see, you are getting a $content property, so you just need to access that property, and as is Base64 encoded, you need to decode it. Try this
"body": {
"fileContent": "#base64ToString(triggerBody()['$content'])",
"fileName": "#triggerOutputs()['headers']['x-ms-file-name']"
},
