So,
I want to send a request from my app to Firebase using cloud funtions and then process process url and send back JSON file from places api
WHAT I HAVE ALREADY DONE/HAVE=>
After Setting up the project in console and getting firebase CLI created a cloud function as follows
After following your comments
this is my full function code:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const rp = require('request-promise');
exports.fetch = functions.https.onCall((req, res) => {
const url = req.url + '&key=MY_API_KEY';
var options = {
uri: url, // Automatically parses the JSON string in the response
json: true
};
rp(options)
.then(result => {
console.log('Get response:' + response.statusCode);
return res.type('application/json').send(result);
}).catch(err => {
// API call failed...
return res.send({'Error': err});
});
})
and in java class passed values like this
private Task<String> addMessage(String url) {
// Create the arguments to the callable function.
Map<String, Object> data = new HashMap<>();
data.put("url", url);///PASSING VALUES HERE
return mFunctions
.getHttpsCallable("fetch")
.call(data)
.continueWith(task ->
(String) Objects.requireNonNull(task.getResult()).getData());
}
Now What my problem is while deploying new function code with firebase CLI I am getting 16:8 error Each then() should return a value or throw promise/always-return
as error
Can anyone guide me please..,
URL will be like this :
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=17.4369681,78.4473887&radius=5000&type=airport&sensor=true&key=MY_KEY
Here are the log details from console
