Send HTTP GET Request using Java 11 HttpClient and parse JSON response into objects

[@nakuldighe8638]

I almost thought it is impossible to learn http requests in java from the internet until i saw this video, thanx man. Great video by the way

[@DanVega]

Wow, that is so awesome of you to say. Thank you for watching.

[@raymondkosos]

Nice! Lot's of API's out there with data returned in JSON format - this tutorial is exactly what I needed to get started! Learning about the .forEach was also a bit of a bonus. I think all I need to do is find this done asynchronously and I'm all set ...

[@DanVega]

Glad it helped!

[@pablohernandez4305]

You saved my life, thank you for this video i had about two days with this topic and it was so easy.

[@rogeriosartori5644]

Thanks man. Great tutorial! Simple and easy to understand. The best tutorial of http request in the internet.

I used to hate Java, but you just did make I love it.

[@nurba_nurba]

video starts from 6:03. thank me later

[@shwetaadurkar562]

Thank you!!..you made it simple and easy to understand.

[@DanVega]

Glad it helped!

[@praveens2272]

Is it possible to map the response with body handler itself ?

[@laponiec]

Is it possible to set multiple headers in our GET/POST method? In my program I need to set the authorization header (basicAuth), and I wonder if I can also set the content type.

[@Armanhannani]

How can I return only one part of json string ?

[@QwinTube]

Its great! Thanks very much!!! Please do more....

[@kostiantynkarzhanov9216]

Great tutorial! Thank you so much! 💛

Clean and clear Sir

how to add password and username for authentication?

[@pajeetsingh]

Do you think adding application related functionality directly into a programming language somehow defeat incentive to learn the language itself?

[@DanVega]

Not at all. Having to write low level code to interact with Http doesn't sound like fun to me. Program languages give us the ability to perform common tasks and I think this is a great abstraction here.

[@devinbaack3578]

How would this work for nested Json?

[@_kishorroy]

This video helped me a lot in my learning phase. Thanks.

[@7thwik]

Can someone explain on how to unit test these requests, responses using mockito ?

[@grrlgd3835]

Tks Dan , very useful. how about to get an image ?

[@zorfrak]

I'm able to retrieve the data from the API, but but I get IllegalStateException("Cipher not initialized"). Can I prevent this?

[@cypherliquid]

what if we want to send a jwt token.

[@vanshrana9508]

It was very helpful, thanks a lot :)

[@DanVega]

You're welcome!

[@michaelnewman2993]

This may be a dumb question, but what if you only need to access a few specific fields of your Json object? For instance if I was using a geocoding api and only needed to return the latitude and longitude. Thanks for the video extremely helpful!

[@conradpeterson1387]

You've probably already figured this out, but you can just add the annotation "@JsonIgnoreProperties(ignoreUnknown=true)" to the object class and then you only have to include variables in the class for the specific fields you want.

[@wiliamferraciolli5380]

Can you show us how to unit test it please? with mockito

[@nidhishah9701]

how can we achieve this with localhost?

[@kriszteblade]

Perfect tutorial.

If i want to consume this web service then how can get object reference of Post class

[@marlegagaming1274]

I'm getting this error, could you please help me out readValue(JsonParser, Class) in the type ObjectMapper is not applicable for the arguments (Object, new TypeReference(){})

[@marlegagaming1274]

Never mind, fixed it, programming in a nut shell🤣 One second : no idea what's going on After making minor changes : I'm the best 🤣😉 Thanks for the great video.

[@hariprasadbs966]

I need this option in single java class file without any server like tomcat,glassfish or others When I try in single java class, I says error: No classdef error HTTPurirequest not found How to fix this

[@FellTheSky]

I need to send first an authentication request to get SESSION ID cookie and then make another request to get the data. Do you have a video about this, or know where i can read it? Im having a hard time finding material

[@alpanajyoti7774]

did you get solution of above query? I have same problem, let me know , If you got solution.

[@FellTheSky]

@@alpanajyoti7774 String cookie = response.headers().firstValue("Set-Cookie").toString(); String cCookie = cookie.replaceAll(".+\\[", ""); String cleanCookie = cCookie.split(";")[0]; System.out.println(cleanCookie) Then on the second request: .setHeader("Cookie",cleanCookie)

[@Hector21211]

[@amirbeheshtian8426]

Great toturial man thanks. Could you please make a toturial for Post method ? specially for this scenario : - Post a Json object ( which include user and pass) - get the value for token in response body.

[@srinivasmurthy3386]

Nice!. Thanks for the g8 video.

[@DanVega]

Thanks for watching!

[@nikhilbansal196]

Thanks for the information. I have a question : how can we send a get request with parameters using HttpClient in java 11?

[@lieutenantflogy6183]

I am curious about this as well. I've been looking for an answer and have yet to find one.

[@abigailedwards1238]

Thanky ou this is exactly what i needed

[@DanVega]

Glad I could help out, let me know if you have any other questions about clients in Java

[@Pritam252]

Why my one says GET() is undefined?

[@DanVega]

Do you have the correct imports? docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpRequest.Builder.html

[@edwinkipruto7125]

that was very easy to understand, would you kindly make a video in consuming rest services using authentications , and web tokens

[@ritiksoni8487]

what was that intro ?

[@DanVega]

It was an old intro I had made. I don't use it anymore though

[@alexandroskourtis5268]

awesome tutorial :)

[@haydn.murray]

Hey Dan - great tutorial!! - What would you recommend when your JSON is a map....ie `{"someData": [{a: 1, b: 2}]}` and all I want is the "someData" value. Map posts = mapper .readValue(response.body(), new TypeReference() {}); posts.get("someData") //

[@DanVega]

Thanks for watching 😊

[@MegaMoses91]

Great Tutorial!

[@andrii5866]

Thanks man. Great tutorial! Have you ever thought about a new video about Spring boot + GraphQl or Spring boot + GraphQl + security? I think it's a great topic for 2020.

[@DanVega]

Thank you. I have really been enjoying using GraphQL on my personal site this past year. Yes, Spring Boot + GraphQL is on my list.

[@jafd7806]

Good content Bro 👌

[@TTYounga]

Thank you so much!

[@ruhnet]

Fantastic video! Thanks so much for taking the time to share it. I'm not fluent in Java but your video was still understandable and useful! One thing though, for future reference, the proper pronunciation of JSON is "jaysun", rather than "jay-sawn". 😀

[@arkanglegeibriel]

"There's a lot of argument about how you pronounce that. I strictly don't care. I think the proper pronunciation is probably..." and then the guy uses a strange french-sounding pronunciation. So who said this? Well that'd be Douglas Crockford, the guy who invented the format. He says it like you do "jaysun". And I know this comment is old, but it's one of the top of this video so I'ma just... correct that number and that statement and move on, have a nice day ^_^

[@30sana]

Honestly after all that ima just consider learning python to use requests easier wtf xD
