Firestore云功能http onRequest'POST'

Question

i've set my firestore cloud function to receive an object from the request, but i get an empty body, i get he data from a Form, then pass it to a variable which i want to send in post request to my cloud firestore function, but i get an empty body, even that the cloud function runs, and i can see the log between the result. My angular side :

 onSubmit(form:NgForm){
    let data = Object.assign({},form.value);
    // const httpOptions = {
    //   headers: new HttpHeaders({
    //     'Authorization': 'secret-key'
    //   }),
    //   body: 'test'
    //  };
     const dataUser = {
       displayName:data.displayName,
       email: data.email,
      password:data.password
     }


    console.log(data);
     this.http.post(this.endpoint,dataUser).subscribe(res => console.log(res));
 }

My node side :

   const functions  = require('firebase-functions');

const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

exports.AddUser = functions.https.onRequest((req, res) =>{

    console.log("B123oo");
     console.log(req.body);
     console.log("Boo");
    // admin.auth().createUser({
    //     email: body.email,
    //     emailVerified: false,
    //     password: body.password,
    //     displayName: body.displayName,
    //     disabled: false
    // }).then(function(userRecord){
    //     console.log("OK !!! UID: ",userRecord.uid);
    // });

 });

result log :

info: User function triggered, starting execution
B123oo
info: {}
Boo

Answer 1

To have a value show as req.body you don't actually assign a value to body. Body is just populated with whatever you send as your data with the request. That body would end up being your second value, dataUser. I noticed you're not passing in your httpOptions, which would normally be the 3rd argument passed to post(). That last part might be your problem. this.http.post(this.endpoint,dataUser,httpOptions)
