Testing callable cloud functions with the Firebase CLI shell

问题

I have been trying new firebase callable cloud functions in firebase functions:shell I keep on getting following error

Request has incorrect Content-Type.

and

RESPONSE RECEIVED FROM FUNCTION: 400, {"error":{"status":"INVALID_ARGUMENT","message":"Bad Request"}}

Here is ho w I am trying to call this function on shell

myFunc.post(dataObject)

I have also tried this

myFunc.post().form(dataObject)

But then I get wrong encoding(form) error. dataObject is valid JSON.

Update:

I figured that I need to use firebase serve for local emulation of these callable https functions. Data needs to be passed in post request like this(notice how its nested in data parameter)

{
 "data":{
    "applicantId": "XycWNYxqGOhL94ocBl9eWQ6wxHn2",
    "openingId": "-L8kYvb_jza8bPNVENRN"
 }
}

What I can't figure still is how do I pass dummy auth info while calling that function via a REST client

回答1:

I managed to get it working running this from within the functions shell:

myFunc.post('').json({"message": "Hello!"})

回答2:

As far as I can tell, the second parameter to the function contains all of the additional data. Pass an object that contains a headers map and you should be able to specify anything you want.

myFunc.post("", { headers: { "authorization": "Bearer ..." } });

If you're using Express to handle routing, then it just looks like:

myApp.post("/my-endpoint", { headers: { "authorization": "Bearer ..." } });

回答3:

If you take a look at the source code, you can see that it is just a normal https post function With an authentication header that contains a json web token, I'd recommend using the unit test api for https functions and mocking the header methods to return a token from a test user as well as the request body

[Update] Example

const firebase = require("firebase");
var config = {
  your config
};
firebase.initializeApp(config);
const test = require("firebase-functions-test")(
  {
    your config
  },
  "your access token"
);
const admin = require("firebase-admin");
const chai = require("chai");
const sinon = require("sinon");

const email = "test@test.test";
const password = "password";
let myFunctions = require("your function file");
firebase
  .auth()
  .signInWithEmailAndPassword(email, password)
  .then(user => user.getIdToken())
  .then(token => {
    const req = {
      body: { data: { your:"data"} },
      method: "POST",
      contentType: "application/json",
      header: name =>
        name === "Authorization"
          ? `Bearer ${token}`
          : name === "Content-Type" ? "application/json" : null,
      headers: { origin: "" }
    };
    const res = {
      status: status => {
        console.log("Status: ", status);
        return {
          send: result => {
            console.log("result", result);
          }
        };
      },
      getHeader: () => {},
      setHeader: () => {}
    };
    myFunctions.yourFunction(req, res);
  })
  .catch(console.error);
