i dont mean to be so offtopic but does anybody know of a method to get back into an instagram account?
I somehow forgot the account password. I appreciate any help you can offer me
This is the best video about http request together with promise. You know how to illustrate the concept top-down and step-by-step. Thank you! Such a wonderful job！
wooow... i think you are the only tutorial on youtube... that actually explains what they are doing, and doesn't waste time building out an entire interface. You actually explain what each line is doing, instead of saying just write this! thank you!
This video proved to be a lifesaver for me. Your Javascript course on Udemy is awesome and there is so much to explore in it. Keep Up the good work Sir.
After a long time , good tutorials on request, thankyou max
I'm in a front end and backend bootcamp and did the javascript classwork for both. Neither explained sending xml requests this well. Thanks man.
Great video. I watch as many of your tutorials as possible from both here and Udemy. I currently on the journey to be a MEAN stack dev and your work has been extremely helpful. Please continue to create great content.
Happy to read that you like my videos Alfred! I'll do my best to keep the videos coming and I wish you all the best on your journey :)
Awesome, the best video about XMLHttpRequest EVER!! Thanks so much for making videos. I'm learning so much!
ERROR:
has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin'
Great Max, Can you add a video about CORS options ?
Yes is there one?
legit godly video. I am using ebay find api to make a ecommerce style app and needed this. our axios request went through but CORS did not allow us to work with it. This is great.
Max, I'm in most of your Udemy courses !! You're my favorite instructor. Thanks so much for making Udemy videos. I'm learning so much!
I really want to thank you for your awesome support here and on Udemy Kerry!
Just what I needed. Thanks a lot Academind. All the broke students thank you :)
Thank you Max. By the way, yes, XHR object is the "old way". It seems to me a bit more complicated than Jquery, Angular or the fetch API way of working the communication between front and backend
Hi, at 5:24.... can anyone explain why xhr.onload comes before xhr.send ()? Thanks
Big fan of you, Max. Just started my RUclips dev channel as well. Thanks a lot for inspiring.
All the best dude
Thank you so much - and good luck for your channel!
@@academind Thanks a lot, Max.
Native is gold, I'm using angular HttpClient daily, but found this way more enjoyable than just using pre-defined things, Thanks lovely max ^^
i used the idea to see how can i validate website if its active or not. but because of CORS error i could not. is there way to do that using the Javascript? thanks
i am following you on udemy..you are best teacher i have seen ..its like whenever i want to learn something new, i wish you had created tutorials for that..i get an absolute understanding after watching your videos.
Hey Max, i've been doing your react course in udemy and I seriously can't thank you enough. Love you ❤️
Wow, thanks so much for your support and your awesome feedback Hamouda!
Thank you! It's a pleasure to watch you! Hello from Moscow.
Very thorough! Thank you, Max!
i started javascript 3 months ago and thnx god they come up with the fetch api
this XML is a nightmare to look at
Hi, Max.
Thanks a lot for your work, you are the best instructor and teacher I have ever met.
Greetings from Ukraine!
Thanks so much Katerina, greetings from Germany :)
Thank you so much, you make learning easier and faster
how to create an javascript interceptor, that intercept every xmlHttpRequest, and show an alert each time the xmlHttpRequest goes in error or errorCode is != 200?
Love your content and the way you cover every important aspect that matters. :)
Thank you very much, I'm very happy to hear you're liking it!
I dont see the point of using promises here? Am i missing something? couldnt we had just returned the response directly? We have the onload method for us.
Did you use promises just to make it analogous to using fetch() api?
Thanks!
It would be cool to look at CORS correct options, abort/canceling requests
Interesting topic, I agree! I'll write that down as a future idea!
@@academind, please do, Max! Struggling with CORS-related issues myself right now :(
Amazing, very helpful and simple to understand
This is the video that I have been looking for, Thank you!
Nice explanation, thanks!
Thanks Max - did you just gotten married? Your face look fresh and younger haha
Thank you, no marriage though ;)
The opposite, he got divorced.
@@academind fall in love then ))) just kidding ) but maybe it's true. Hi, from Köln!)
The would mean he got divorced
I'm not to sure how to make a javascript fetch URL where you paste it in the bar on a browser then it sends back the cookies
Please help me!
in 8:49 you mistyped the 'url' at first, with the 'z' instead of the 'u'. I assume that those two keys are very close to each other in the keyboard you use. What type of keyboard layout do you have?
I got this message: "WSDoAllReceiver: Request does not contain required Security header" :( What can i do?
I'm glad I found this, thank you, and were you able to do a video about CORS options?
Great video Max, could you also throw some light on WebAssembly?
Thanks Max! Cool video, as always!
Thanks Max! You out this topic in pieces. Very clear
Thank you so much!
I'm so glad `fetch()` exists
But does fetch work in prod?
How can I use it whilst avoiding SPA frameworks?
@@FordExplorer-rm6ew fetch is great for simple async requests and it's built into javascript. For production you might be better off using Axios for all of the built in features.
Good one! It would be great if you will make more videos about native js
Wonderful...thank you a lot for this lesson...
im applying for a payment integration on my website
and the merchant gave me files to send xml request
but im totally confused
any helP>>>>
?????????????????????????????
Thanks Max, Your contents are very well explained.
stuck with the CORS issue.. please help
Hi, I am getting access-control-allow-origin error when using the Tesla API, xmlHttpRequest via javascript, do you have any advice
I am having problem when I implement POST method error 404 (Not Found). But it works perfectly on GET method. Please help.
Back to the basics :) Thanks. helped me understand the concept of promises.
Happy to read that Moran, thank you!
How do you get around hard coding the url?
Is it possible to send an SSL request via axion or xml or fetch or how can I make my nodesjs app does the request in the browser
The google API doesn’t recognise the XMLHttpRequest function
Is this normal? What should I do
I'm lost - when I add xhr.setRequestHeader('Content-Type', 'application/json');
I get a "Access to XMLHttpRequest at 'api.......' from origin 'localhost:4200' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values 'localhost:4200, *', but only one is allowed."
When I delete the xhr.setRequestHeader bit, I get this error message: "Content type 'text/plain;charset=UTF-8' not supported". So I have to go back to set the headers to read json, right? It's a catch 22!!!!!!
Thank you Max!
Nice explanations and examples, so I understood all the material of the video !
Thanks a lot Dimitris!
hello my API keeps retruning HTML and so i cant run my search box to call the API
do you know how to solve this issue?
in your code i get null and so i have to comment out responseType line and then i just get HTML code in the console
this is a sample API call
gigablast.com/search?format=json&q=Lisa
thxz for any help i been trying to solve this myself and online for 3 weeks
Lisa
does anyone know the fix for this?
i followed the code for fetch from david ceccia but i still get only HTML
and so i will also get cant parse error < because thats the 1st caracter of an HTML page
i am blocked by CORS Policy while trying to getData :(
can anybody make me understand the sequence of execution of that code???????
how to get json using param (id) ?
Very good instructor! Thank you for sharing your knowledge
really great tut man, clear explanations.
One more bonus as usual. Thanks
Hello
I am very new to JavaScript and API Automation.
My project uses POST APIs with XML request (with input value tags and userid and password) and XML response. and using JEST framework.
Can you please help me building a simple test with handling XML request response, Headers, URL, authorization key ?
That was soo cleann
Great subject - very well explained!!
Very informative.
Thank you so much
Thanks that was extremely helpful.
Thank you, I am following you very long time and I learnt a lot from your video but my one concept is never clear about promises and async and await. I would like to ask could you please comment here function getData using async, await this will clear my doubt.
Thanks you!!!
can i save the responce value in a var?
Can you make video about extension chrome
GENIAL!
thanks you.
What font are you using?
Hi.
I have some problems :)
I have trying to call from js, like you, into a django-api-rest which is created by me and it s on localhost the same :)
i have this error :
access has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
you need to download cors package for django using pip and add some code in settings.py middleware to enable policy
And then in reality, you don't always direct access to JSON. At my job the reason for this is that the JSON data is dynamically generated. At which point you will have to manually build the http request header and then use a decompression algorithm to get the JSON data on the response header.
Wow, this is really hard to wrap my head around. This video helps a lot, but Idk man, this stuff is hard
Nice one! I started back then with XMLHttpRequests, and made a jump later to the fetch API / jQuery's ajax-API. Old-used thing, those XMLHttpRequests, but they remind me of my beginning in web development. I remember a time, when i loaded whole HTML pages via XMLHttpRequests - something i would never do nowadays. But "ich schweife ab" ... - nice video!
Thanks for sharing this video. Yeah I did understood something but after 12 minutes it was difficult to understand .
Will it work with nodejs on server side?
hope subtitles for future
It's sad that there is no eng sub
i feel u
fun fact: axios uses xhr in browser and http/https modules in nodejs
Can we send request with custom header ?
great tutorial. thanks!
Jquery, 3 lines, done 😉
Not the idea behind the video though ;-)
not worth the shame ;)
Plz, max more explain http2 and how to use it?
really thanks
I don't get why start using recent methods when the whole point of using XMLHttpRequest is to use it in legacy projects where those methods are not available, I think you should've stayed with the traditional way of doing XMLHttpRequest and not introduce promise or async await etc
Nice , thanks
9:11 promise example
Thank you for this video
What happenes if given url is wrong
nothing are raten in the console and no error just nothing happen
Now that I've been building and deploying applications for some time now...
My question really isn't so much about Ajax , libraries , or the xhr object itself, but...
More so,
*How do these things work in prod?*
How can I avoid those icky CORS errors?
What is best practice for stuff like that?
I see all of these tutorials , and it's like, yeah... that's nice for my local machine...
But I'm concerned about prod and others.
The duct tape and glue way to avoid it seems to be, to make hybrid php/JS applications on apache and express (2 servers)
Or figure out how to connect websockets (to work in prod mind you)
Idk, kinda wanna avoid the whole hybrid php/js thing.
Or is that just something one has to go through?
Surely there are better ways?
Idk.
Vielen Dank!:)
Thanks for Good Work :)
Max, please include subtitles for this video, thank you...
Great! Thank you :-)
