c# - How to parse form data using Azure Functions -

i trying form data within azure function.

public static async task<httpresponsemessage> run(httprequestmessage req, tracewriter log) {     log.info("c# http trigger function processed request.");     namevaluecollection col = req.content.readasformdataasync().result;        return req.createresponse(httpstatuscode.ok, "ok"); } 

i getting following error:

exception while executing function: system.net.http.formatting: no mediatypeformatter available read object of type 'formdatacollection' content media type 'multipart/form-data'.

i trying parse inbound emails via sendgrid described here. https://sendgrid.com/docs/classroom/basics/inbound_parse_webhook/setting_up_the_inbound_parse_webhook.html

the incoming request looks correct.

--xyzzy content-disposition: form-data; name="attachments"

0 --xyzzy content-disposition: form-data; name="text"

hello world --xyzzy content-disposition: form-data; name="subject"

subject --xyzzy content-disposition: form-data; name="to"

based on error message, using multipart/form-data request content type. haven't post media type data server.

if want send plain data server, change content type application/x-www-form-urlencoded , modify request body following format.

name=attachments&anothername=anothervalue 

if want form data multi part post, using multipartformdatastreamprovider.

string filepath = "set temp path store uploaded file"; var provider = new multipartformdatastreamprovider(filepath); var multipartprovider = await req.content.readasmultipartasync(provider); var formdata = multipartprovider.formdata; 

manually parse content of request body.

string content = await req.content.readasstringasync(); string formdata = content.split(';')[1]; string[] namevalues = formdata.split('&'); namevaluecollection col = new namevaluecollection(); foreach (string item in namevalues) {     string[] namevalueitem = item.split('=');     col.add(namevalueitem[0], namevalueitem[1]); }
