Shoutout to @anzharip.
This piece of code did wonders for me. We're utilizing the @anzp/azure-function-multipart module in our code.
Here's my implementation:
HttpTrigger1/index.ts:
import { AzureFunction, Context, HttpRequest } from "@azure/functions";
import parseMultipartFormData from "@anzp/azure-function-multipart";
const httpTrigger: AzureFunction = async function (
context: Context,
req: HttpRequest
): Promise<void> {
const { fields, files } = await parseMultipartFormData(req);
context.log("HTTP trigger function processed a request.");
const name = req.query.name || (req.body && req.body.name);
const fileContent = files.length > 0 ? Buffer.from(files[0].bufferFile).toString('utf-8') : null;
const responseMessage = {
fields,
files:[
{
...files[0],
fileContent,
},
],
};
context.res = {
body: responseMessage,
};
};
export default httpTrigger;
hello.txt:
Hello, this is file data of hello.txt
