title: How to get parameters from request in cloud functions? Firebase
body: <p>I made https cloud functions, and I make a request to it with the iOS app. The Cloud function is called, since I can see the log, but I can not get the parameters from the request that I sent from the iOS app. I tried several different options but they helped me, please tell me how I can achieve the result?</p>
  
  <pre><code>const functions = require('firebase-functions');
  const admin = require('firebase-admin');
  
  module.exports = functions.https.onRequest((req, res) =&gt; {
      console.log("getChatGroupConversationAvatars start", req.params);
      const requestDict = req.params;
      console.log("requestDict", requestDict);
      const queryFormat = req.query.format;
      console.log("queryFormat", queryFormat);
      const conversationID = requestDict["conversationID"];
      const currentUserID = requestDict["currentUserID"];
  
      console.log("conversationID", conversationID, "currentUserID", currentUserID);
  
      return console.log("getChatGroupConversationAvatars");
  });

  <p>iOS app code </p>
  
  <pre><code>class ChatAvatarsManager {
  
      func getChatGroupConversationAvatars(_ conversationID: String) {
          DispatchQueue.main.async {

                  guard let url = URL(string: path) else { return }
                  let parameters = ["conversationID" : conversationID, "currentUserID" : currentUserID]

  <p>For example I got this result in logs </p>
  
  <pre><code>conversationID undefined currentUserID undefined
  </code></pre>
  
  <p>I also tried it</p>
  
  <pre><code>module.exports = functions.https.onRequest((req, res) =&gt; {
  
      const conversationID = req.params.conversationID;
      const currentUserID = req.params.currentUserID;
  
      console.log("conversationID", conversationID, "currentUserID", currentUserID);
  
      return console.log("getChatGroupConversationAvatars");
  });
