VistasCosmosDB REST API - Create document from node-red request node
I have a node-red flow from where I want to post a json object to Azure CosmosDB using the CosmosDB REST API. Below is a code snippet in JavaScript (node red function node) for building the POST request and as well generate the signature. I get response from Cosmos that the message is not properly formatted: "HTTP Error 400. The request is badly formed". Does anyone know what I´m doing wrong here? I´v included an image for the HTTP Request where we can see the headers and json body.
const { crypto } = context.global;
function getAuthorizationTokenUsingMasterKey(verb, resourceType, resourceId, date, masterKey) {
var key = new Buffer(masterKey, "base64");
var text = (verb || "").toLowerCase() + "\n" +
(resourceType || "").toLowerCase() + "\n" +
(resourceId || "") + "\n" +
date + "\n" +
"" + "\n";
var body = new Buffer(text, "utf8");
var signature = crypto.createHmac("sha256", key).update(body).digest("base64");
var MasterToken = "master";
var TokenVersion = "1.0";
return encodeURIComponent("type=" + MasterToken + "&ver=" + TokenVersion + "&sig=" + signature);
}
var url = "https://myurl.documents.azure.com/dbs/FamilyDatabase/colls/FamilyContainer/docs/"; //id here???
var key = "mysecretkey";
var resourceId = "FamilyContainer"; //"dbs/FamilyContainer" ??;
var authToken = getAuthorizationTokenUsingMasterKey("POST", "dbs", resourceId, new Date(), key);
msg.headers = {};
msg.headers['Authorization'] = authToken;
msg.headers['Accept'] = '*/*';
msg.headers['Accept-Encoding'] = '*/*';
msg.headers['Content-Type'] = 'application/json';
msg.headers['x-ms-documentdb-partitionkey'] = 'Andersen';
msg.headers['x-ms-version'] = "2018-12-31",
msg.headers['x-ms-date'] = new Date().toString();
msg.url = url;
msg.method = "POST";
msg.body = msg.payload;
/*
//I have tried different varaitios in the body here
msg.body = {
"data": msg.payload
//"id": "AndersenFamily"
}
msg.payload = {
"data": msg.payload
//"id": "AndersenFamily"
}
*/
return msg;
