I want to create sample script to login at my website.
My script like this :
var page = require("webpage").create();
var system = require("system");
var data = {
"username": system.args[1],
"password": system.args[2]
}
function login(data){
page.open("http://localhost/mywebsite/login.php", function(){
page.includeJs("https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js", function(){
console.log("Come in here.");
phantom.exit();
)}
)}
}
login(data);
When I run phantomjs in terminal, example : phantomjs myscript.js admin admin
i dont get anything in my terminal.
what's wrong in my code?
The way you closing callbacks is wrong. you are closing like this )}.it should be });
Your code here
var page = require("webpage").create();
var system = require("system");
var data = {
"username": system.args[1],
"password": system.args[2]
}
function login(data){
page.open("http://localhost/mywebsite/login.php", function(){
page.includeJs("https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js", function(){
console.log("Come in here.");
phantom.exit();
});
})
}
login(data);

I'm using cypress to test my VueJS application. The one thing I'm having trouble with is mocking an image to be displayed on the page. For my use case, I'm simply loading a user profile with the following code:
describe('Test Login', () => {
it('Can Login', () => {
cy.server();
cy.route({
method: 'GET',
url: '/api/account/',
response: 'fx:profile.json',
});
cy.route('**/media/demo1.png', 'fx:demo1.png');
});
});
fixtures/profile.json
{
"avatar": "http://localhost:8080/media/demo1.png",
"username": "cypress",
"email": "email#cypress.io",
"pk": 1,
"is_staff": true,
"is_superuser": true,
"is_active": true
}
The profile fixture data is loading correctly in the test. In my fixtures folder, I also have a demo1.png file. I am expecting this image to be loaded and displayed on the page during my test, but it is being displayed as a broken image.
In the network tab, it shows demo1.png as a broken image with a 200 response code and type of text/html.
The cypress documentation mostly discusses images in the context of uploading images, but I haven't been able to find an example of how I can mock an image that is loaded through a <img> tag. Is there an easier way of doing this?
I am not sure if this answer can help you. But at least it is a workaround for this problem ;-)
Say we have a HTML like this:
<html>
<body>
<button id="button">load</button>
<div id="profile">
</div>
<script>
function httpGetAsync(theUrl, callback)
{
var xmlHttp = new XMLHttpRequest();
xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4 && xmlHttp.status == 200)
callback(JSON.parse(xmlHttp.responseText));
}
xmlHttp.open("GET", theUrl, true); // true for asynchronous
xmlHttp.send(null);
}
document.getElementById("button").addEventListener("click", () => {
httpGetAsync("/api/account/", (result) => {
var div = document.querySelector("#profile");
var img = document.createElement("img");
img.src = result.avatar;
div.appendChild(img)
})
})
</script>
</body>
</html>
source: HTTP GET request in JavaScript?
And you want to load the profile after the click was done. Then you can use MutationObserver to replace the img.src.
First, write the MutationObserver:
var observeDOM = (function(){
var MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
return function( obj, callback ){
if( !obj || !obj.nodeType === 1 ) return; // validation
if( MutationObserver ){
// define a new observer
var obs = new MutationObserver(function(mutations, observer){
callback(mutations);
})
// have the observer observe foo for changes in children
obs.observe( obj, { childList:true, subtree:true });
}
else if( window.addEventListener ){
obj.addEventListener('DOMNodeInserted', callback, false);
obj.addEventListener('DOMNodeRemoved', callback, false);
}
}
})();
(heavily copy & pasted from Detect changes in the DOM)
Now you are able to do this:
describe('Test Login', () => {
it('Can Login', () => {
var win = null;
cy.server();
cy.route({
method: 'GET',
url: '/api/account/',
response: 'fx:profile.json'
});
cy.visit("index.html").then(w => {
cy.get("#profile").then(pro => {
var e = pro[0];
observeDOM(e, (m) => {
// add a red dot image
m[0].addedNodes[0].src = "data:image/png;base64,"+
"iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAABGdBTUEAALGP"+
"C/xhBQAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9YGARc5KB0XV+IA"+
"AAAddEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIFRoZSBHSU1Q72QlbgAAAF1J"+
"REFUGNO9zL0NglAAxPEfdLTs4BZM4DIO4C7OwQg2JoQ9LE1exdlYvBBeZ7jq"+
"ch9//q1uH4TLzw4d6+ErXMMcXuHWxId3KOETnnXXV6MJpcq2MLaI97CER3N0"+
"vr4MkhoXe0rZigAAAABJRU5ErkJggg=="
})
})
cy.get("button").click()
})
});
});
(yeah at least some lines of code are written on my own ;-P)
You can read the image from the img.src attribute from the fixtures folder. For the sake of simplicity I have used a static base64 string here.
And the result:
We are not using this kind of stuff in our aurelia app but I tried similar things in a private project some time ago.
i have installed the phantomjs 1.9.7 & casperjs 1.1.0 and now i see that all my scripts need to be updated and to remove the first line since it makes the below fatal error:
Fatal: you can't override the preconfigured casper instance in a test environment.
Docs: http://docs.casperjs.org/en/latest/testing.html#test-command-args-and-options
Reading also in another question i understand that i have to remove now this line from my scripts:
var casper = require('casper').create();
Which is a lot of work since i have meanwhile more then 200 script that needs to be updated!!!
So my question is how can i overcome this issue without updating all the scripts (mentioned in Can't run the testing framework in CasperJS)
var casper = require('casper').create();
if (casper.cli.has("ip") === false) {
casper.echo("Usage: casper.js test get_info.js --ip=<x.x.x.x>").exit();
}
casper.test.begin('get info', 1, function suite(test) {
casper.start("http://" + casper.cli.get("ip") + ":xxxx/man/", function() {
test.assertTitle("TEST GUI", "GUI has the correct title");
test.assertExists('form[name="loginForm"]', "login form is found");
this.fill('form[name="loginForm"]', {
'userId': 'xxxxx',
'password': 'yyyyy'
}, true);
});
casper.then(function() {
test.assertTextExists("Welcome", "Login into TEST GUI");
this.click('a#test_menu.menu1itemUnSel[tabindex="4"]');
});
casper.then(function() {
casper.wait(5000, function() {
this.echo('should appear after 5s');
});
});
casper.then(function() {
test.assertTextExists("TEST Data", "Login into Data");
this.click('a#test_menu_data.menu2itemUnSel[tabindex="4"]');
});
casper.then(function() {
casper.wait(5000, function() {
this.echo('should appear after 5s');
});
});
casper.then(function() {
test.assertTextExists("Logout", "Loggin out from TEST GUI");
this.click('a.minorLinkshighlight');
});
casper.run(function() {
test.done();
this.exit();
});
});
The above script was working before i installed the phantomjs 1.9.7 & casperjs 1.1.0, the only thing that i can't recall is which version i had before my server had to be reinstalled!
Thanks in adv.
Yes this is my way of avoiding updating old casperjs scripts due to the overriding of the preconfigured casper instance in a test environment!
go to the casperjs path and edit in path modules:
/../casperjs/modules/casper.js
and remark out the below lines:
exports.create = function create(options) {
"use strict";
// This is a bit of a hack to check if one is trying to override the preconfigured
// casper instance from within a test environment.
// if (phantom.casperTest && window.casper) {
// console.error("Fatal: you can't override the preconfigured casper instance in a test environment.");
// console.error("Docs: http://docs.casperjs.org/en/latest/testing.html#test-command-args-and-options");
// phantom.exit(1);
// }
return new Casper(options);
};
This worked for me. You should use it only on your own risk!
consider the following snippet.how can i access the value of the page url outside the page context?globally accessing the value was not working either.callbacks wasn't clear to me in approach.
page.onUrlChanged = function(targetUrl) {
console.log('New URL: ' + targetUrl);
};
page.onConsoleMessage = function (msg) {
console.log(msg);
};
var abc=page.open(url,function(status){
page.evaluate(function(){
//some code;
})
return page.url;
});
console.log(abc);
the code always gives undefined page url.
PhantomJS documents are very much recommended: http://phantomjs.org/api/webpage/method/evaluate.html
page.open(url,function(status){
var current_url = page.evaluate(function(){
return document.location.href;
})
console.log(current_url);
});
I have a SqlDataAdapter and I want to store it in a JsonStore collection in MobileFirst and Display it in table form. I have tried using Load() method but its not working.
this is my resultSetCollection.js file
;(function () {
WL.JSONStore.init({
resultSet : {
searchFields: {"EMP_NAME":"string","EMP_ID":"integer"}
}
}, {
// password : 'PleaseChangeThisPassword'
})
.then(function () {
return WL.Client.invokeProcedure({
adapter : 'EmployeeList',
procedure : 'getEmployeeLists',
parameters : []
});
})
.then(function (responseFromAdapter) {
alert('responseFromAdapter:' + JSON.stringify(responseFromAdapter.invocationResult.resultSet));
var accessor = WL.JSONStore.get('resultSet');
var data=responseFromAdapter.invocationResult.resultSet;
var changeOptions = {
replaceCriteria : ['EMP_ID', 'EMP_NAME'],
addNew : true,
markDirty : false
};
return accessor.change(data, changeOptions);
})
.then(function (response) {
console.log(response);
//Here I want to retrieve the collection and display it in a table
})
.fail(function (errObj) {
WL.Logger.ctx({pretty: true}).error(errObj);
});
}());
An adapter procedure request from a client application will have a response object in its success and failure callbacks. So lets assume that the request was successfull and data was returned from the backend server.
Lets also assume you have a JSONStore initialized and properly setup with a collection. You then only need to get the collection and add data to it.
The below example takes the full response from an HTTP adapter request and puts it as-is into a collection. You will of course need to create a better setup for your specific scenario...
Note that the code is not optimised and performance or with 100% proper logic. It's just a demonstration flow.
Tested in MobileFirst Platform Foundation 7.0.0.00.
main.js:
var collectionName = 'mydata';
var collections = {
mydata : {
searchFields : {data: 'string'},
}
};
function wlCommonInit(){
WL.JSONStore.init(collections).then(
function() {
var resourceRequest = new WLResourceRequest("/adapters/myadapter/getStories", WLResourceRequest.GET);
resourceRequest.send().then(resourceRequestSuccess, resourceRequestFailure);
}
);
}
function resourceRequestSuccess(response) {
WL.JSONStore.get(collectionName).add(response).then(
function(){
WL.Logger.info("successfully added response to collection");
displayDataFromCollection();
},
function() {
alert("failed adding response to collection");
}
);
}
function resourceRequestFailure() {
alert ("failure");
}
If you then like to fetch the data from the JSONStore and display it in the HTML, you could do something like this:
// get a specific item from the stored response and display it in a table
function displayDataFromCollection() {
WL.JSONStore.get(collectionName).findAll().then(
function(result) {
$("#mytable").append("<tr><td>" + result[0].json.responseJSON.rss.channel.title + "</td></tr>");
},
function() {
alert ("unable to display collection");
}
);
}
The index.html looks like this:
<table id="mytable">
</table>
I've followed examples for injecting jQuery from the getting started page and that works just fine. I have a local copy of jQuery in the same directory, and do something like...
if(page.injectJs('jquery.min.js')) {
page.evaluate(function(){
//Use jQuery or $
}
}
When I try to inject my own script(s), none of the functions are available to me. Say I have a script called myScript.js that just has
function doSomething() {
// doing something...
}
I cannot then use doSomething like...
if(page.injectJs('myScript.js')) {
console.log('myScript injected... I think');
page.evaluate(function() {
doSomething();
});
} else {
console.log('Failed to inject myScript');
}
I've tried
window.doSomething = function() {};
and
document.doSomething = function() {};
as well with no luck, as well as trying to call them with window.doSomething() or document.doSomething() in the subsequent page.evaluate().
The following works for me, maybe some other part of your app logic is wrong:
inject.coffee
page = require('webpage').create()
page.onConsoleMessage = (msg) -> console.log msg
page.open "http://www.phantomjs.org", (status) ->
if status is "success"
page.includeJs "http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js", ->
if page.injectJs "do.js"
page.evaluate ->
title = echoAndReturnTitle('hello')
console.log title
phantom.exit()
do.coffee:
window.echoAndReturnTitle = (arg) ->
console.log "echoing '#{arg}'"
console.log $(".explanation").text()
return document.title
Result:
> phantomjs inject.coffee
echoing 'hello'
