I have seen this question, and read this documentation, but still i cannot get the url as string value.
I know that in protractor, you should use the below code to get url:
import {browser} from 'protractor'
browser.waitForAngular();
var url = browser.getCurrentUrl()
console.log("URL is: "+url);
But, when i run the code in the console i have:
URL is: ManagedPromise::253 {[[PromiseStatus]]: "pending"}
Also, the documentation specifies that the result of function is a promise that will be resolved with the current URL.
But, i am wondering, why i am not able to get it as a string?
browser.getCurrentUrl() returns a promise.
You have to resolve the promise to get the current URL.
var currentUrl = browser.getCurrentUrl().then(function(url){
console.log(url);
return url;
});
As you could see from documentation the getCurrentUrl() method return !webdriver.promise.Promise.<string>, translated to people language the method return Promise that contains string. So you need, firstly, to resolve Promise. I highly recommended to read this article for getting understanding.
Example with async ... await:
async function pageUrl() {
const url = await browser.getCurrentUrl();
return url;
}
import {browser} from 'protractor'
browser.getCurrentUrl().then((url) => {
console.log("URL is: "+url);
})

I am struggling to find a solution to proceed with my program when a listener completes.
So my main goal is it to return a queryParameter of the DeepLink that leads back to my app. I already found out how to get the params with uni_links :
String function(){
linkStream.listen((String? link) async {
if (link!.startsWith(redirectUri)) {
param = Uri.parse(link).queryParameters['code'].toString();
print(param);
}
});
}
But now I want to return param instead of just printing it into the console. The problem is, because the return type of a listener is Future<void>, I am not able to just return the String without some kind of a workaround.
Is there a way to solve this?
I'm having some problems with a line in the function below. The function is handling async gets from Firebase Storage. I'm using it to get the names and urls of files I have stored there.
The issues is with getting the Urls. Specifically on the line:
String url = element.getDownloadURL().toString();
getDownloadedURL() is a Firebase future. I tried to await it, but it won't recognise the await, I guess due to "element".
The over all effect is that when I'm using this in my UI via a Future builder, the name comes out fine but the Url doesn't. It is being retrieved as the print statement shows it. But it's not being waited for, so the UI is already updated.
Been trying lots of things, but haven't found a solution, so any help would be greatly appreciated.
Future<void> getImageData() async {
final imagesFromStorage = await fb
.storage()
.refFromURL('gs://little-big-deals.appspot.com')
.child('images')
.listAll();
imagesFromStorage.items.forEach((element) {
print(element.name);
String url = element.getDownloadURL().toString();
print(url.toString());
imageData.add(ImageData(element.name, url.toString()));
});
}
Many thanks
You can't use async in forEach.
Just use a for loop:
Future<void> getImageData() async {
final imagesFromStorage = await fb
.storage()
.refFromURL('gs://little-big-deals.appspot.com')
.child('images')
.listAll();
for (var element in imagesFromStorage.items) {
print(element.name);
String url = (await element.getDownloadURL()).toString();
print(url.toString());
imageData.add(ImageData(element.name, url.toString()));
}
}
I'm trying to query a collection of users using Mongoose in a Node API.
The handler looks like this:
exports.getUsers = async function(req, res, next) {
try {
let users = db.User.find();
return res.status(200).json(users);
} catch(e) {
return next(e);
}
};
This returns an error that reads Converting circular structure to JSON. When I console.log() the results of db.User.find(), I get a Query object. I've checked everything else. All of my other routes are working normally.
Well...I figured it out. I'll post the answer that I discovered in case anyone else is trying to figure this out. It turns out, through a little bit more careful reading of the documentation, that the Query object that is returned has to be executed. There are two ways to execute it - with a callback function or by returning a promise (but not both). I found this page on queries in the mongoose docs helpful. My final handler looked like this.
exports.getUsers = async function(req, res, next) {
try {
db.User.find()
.then(users => {
return res.status(200).json(users);
});
} catch(e) {
return next(e);
}
};
Next time I guess I'll dig around for a few more minutes before asking.
Edit to add:
Found a second solution. Due to the use of the async function, I also was able to use following inside the try block.
let users = await db.User.find();
return res.status(200).json(users);
I am running an automation script. We have a scenario where Java makes a callback REST call to UI. Below is the code where am doing httpGet to that URL. I want to know when the response comes. If it comes how to know that. I searched a lot I din't find a clear answer anywhere. Please give some hints!
http.get(siteUrl, function(response) {
var bodyString = '';
response.setEncoding('utf8');
response.on("data", function(chunk) {
bodyString += chunk;
});
response.on('end', function() {
defer.fulfill({
statusCode: response.statusCode,
bodyString: bodyString
});
});
}).on('error', function(e) {
defer.reject("Got http.get error: " + e.message);
});
//If we are sure that response has come, then extract it
httpGet("http://testurl").then(function(result) {
//alert('inside test automation');
console.log(result);
});
You can use the response detail whether success or fail with "response code", there are lots of way using interface as callback, using methods by checking response code, lots of network library available - volley, okhttp rest client etc...
help : response code detail
if(response.statusCode == 200) {
// do success work read response etc...
// you can call methods what you want if success happen
} else {
// you can check other status code too..
// call methods if api get fail.
}
Hope this would help
good luck.
I am using Redux and trying to make a call to Facebook API with their JS SDK. I've only ever used promises with Redux and so since the method FB.getLoginStatus just returns a simple JS object, I'm not sure how to ensure that the payload doesn't return undefined.
With redux-promise, you add it to the applyMiddleware(ReduxPromise)... and then it ensures nothing is returned until the promise resolves. But I don't know how to do that here.
I've also used async/await functions with React Native without an issue, but I tried using them here and for some reason the code still returns the payload, before the asynchronous request (await ...) is finished. So I tried working with redux-await, but couldn't get it to work.
export function getLoginStatus() {
var res = FB.getLoginStatus(function(res) {
console.log(res);
});
console.log("res ", res);
return {
type: GET_LOGIN_STATUS,
payload: res
}
}
Hm, things can get a little tricky as I've not used redux-promise. And I can't tell exactly what else you have tried. But this would be my first shot:
async function _getLoginStatus() {
var payload = new Promise( (resolve, fail) => {
FB.getLoginStatus((res)=>resolve(res));
});
return {
type: GET_LOGIN_STATUS,
payload: payload
}
}
// Last time I exported an async function I needed this HYMMV
export let getLoginStatus = _getLoginStatus;
And then elsewhere in the code:
import {getLoginStatus} from 'whatever.js';
var payloadResult = await getLoginStatus();
