Recently, I'm building an application this must request to server to get data from this. I use GTK+ to coding.
I search in the internet many times. but I don't get result i can use. So anyone can taught me how to request to server by json to get data from server
Take a look at Libsoup, it does what you want and integrates with GLib and GTK. Here is a tutorial that explains how to use it and how to do a HTTP POST.

I've started to learn backend development, focus on http server mainly.
But I'm really new to this, so it's a little out of focus for me, and I could really use some advice.
For example, if I try to implement something like this
A http server runs on linux/Windows
A private REST API which allows to POST a json object, plus a login mechanism, so only authorised user can do the POST.
Implement a public REST API which allows to GET the same json object
And here is my question:
Can I use Nodejs and express to implement all these? I also know little about them.
Do I need a Database to implement the login mechanism?
Is there any similar tutorial or best practise I can study from?

Yes, you can use NodeJS for this.
Not necessarily. You just need a way to authorise users. Most common is to use a database to store a username/email and password, but you could also look into using a third-party service for this, for example facebook or google
Yes, there is a lot of tutorials and especially best practices on this subject. Your question is too broad to link relevant material, but some terms you can use to google this yourself is "nodejs rest api" "rest api best practice". Passport.js is a good place to start for getting into authorising users. For REST-api, the closer you get to normal web standards, the better - Especially if other people than you are going to consume the api.
Node.js is a run-time environment/framework/platform for developing non-blocking I/O server side processes, services, or RESTful API's. You can start by learning what Node.js can do before you go on developing a login story and, and a restful endpoint here
Next if you intend to go all the way and learn full-stack web development start from here, This will guide you to learn Node.js , Express.js, Mongodb, and finally Angular.js for front-end. Good luck and happy coding
Yes, you can use Node.js and Express.js. I recomend you to read some articles about REST and TDD from this amazing blog, especialy this or this.
I'm new to Node so maybe someone can help me in this decision, I want to create RESTFul API that are accessible from a web site and from mobile application returning JSON response.
I have decided to use the same API for the website and for the mobile applications for a maintain purpose, I went from a disastrous platform where the two logic part were separated. Also I want to use only RESTFul API without session for a scalability purpose, using an OAuth2 authentication and maybe Memcache to serve same JSON response thanks to the hash algorithm used.
I begin with Node+Express.js+MongoDB for the backend, but I have noticed that Express come with a lot of package to control and use cookie, template engine and so on...
So my question is: Express.js is the right package for my purpose? Or is better to not use this Framework? In your opinion what is the best way to achieve speed of access and speed of serving without any type of session and without any type of cookie?
I developed some RESTful APIs with Express. The good thing about Express is that you don`t need to use all the additional stuff like session handling and template engines.
In addition there are some really good modules that enables you to set up an API very fast.
For example if you are using mongoose have a look at Baucis.
If you still feel uncomfortable with Express, there are many other node.js frameworks for building RESTful APIs. Maybe give Restify a try?
Restify is somehow like a specialized version of Express, so it is really easy to migrate existing code.
You can go for Strongloop as well. Strongloop is a wrapper on express, but it has many features which makes it very powerful for building RESTful APIs.Please check this link https://strongloop.com/
I am looking for a API or Documentation for developing a IMAP-Client for POSTFIX. I am planning to use html5 for front end and php for backend.
The fact that your mail server runs on postfix is completely irrelevant. You should learn about the IMAP protocol, and to be able to use it, you can start with the PHP IMAP functions.
Sorry for pointing directly to the manual but when you have some code to show us, you can go back and explain where you got stuck and then we can try to help again.
I am really a beginner in delphi, as the client request the project to be done in delphi, so I have to ask to get some help as possible as I can. This project will be involved in HTML5 and websockets as well, so there are some questions I need your advices.
Sorry let me explain more, this application have two parts mainly, one is HTML5 client web app (this app will be loaded from web server, and run locally in browser), and the other is its service located in server. The HTML5 web app is doing some product editing job, as well send its final output to server, during this process, there will be many communications between client app and service, and I planed to use Websockets.
I did plan this application in HTML5 and Node.js before, but as client send request to ask for the Delphi XE as primary development tool also it will be compiled to DLL (ISAPI, have to be) at last. For consistency of UI, I also was required to use uniGUI (http://www.unigui.com/demo)for Delphi. Now I have these questions:
Is there any other way to do this application with HTML5 as web front exclude uniGUI in Delphi?
What good libraries support Websockets in Delphi?
What book you can recommend me to read, as I don't know Delphi at all.
Thanks.
1: yes, make a "single page app" (static html + js) and communicate with server using xml or json.
At least with indy 10 it is quite straight forward to implement static file serving (response.contentstream := tfilestream.create(sfilename) or something like that)
2: yes, if you search for it on google you will find some :)
WebSocket server implementations for Delphi
btw, I'm busy with delphi socket.io implementation, which makes it easier to use websockets instead of plain low level tcp-like websockets itself
Is there any other way to do this application with HTML5 as web front exclude uniGUI in Delphi?
First concept : HTML5 applications are a bunch of HTML files and JS's wich can be processed by browsers.
Second concept : You need an application that can bind HTTP queries and return files from the first concept.
Third concept (paradigm) : With first two concepts, a third concept arises. Dynamic HTML. What is dynamic HTML? HTML that generates at runtime at the backend server and/or at frontend with JS.
Solution :
Yes, with Delphi as a backend server you can manipulate and return HTML5 views, if you know (MVC paradigmn for example) you can program an HTTPServer application that binds HTTP request from network and responses your HTMLs and JS.
What good libraries support Websockets in Delphi?
You need a multilayer library. The best library I know is mORMot. mORMot is like a swiss razor for Object Pascal.
You can create an HTTP server with websocket published interfaces. mORMot's Site
What book you can recommend me to read, as I don't know Delphi at all.
I have more than 10 years with Delphi and Free Pascal and I didn't read a book at all. But I read a lot from internet and a lot of computer architecture and another languages like C and C++.
If you like Delphi there are tons of documentation via Internet. I cannot recomend you a book because I will lie you.
We have project developed in Silverlight/DevForce services, currently we plain to move code into HTML5. My question is it possible to reuse server side part of project, I means is it possible to reuse DevForce services or better migrate to WebAPI services? IdeaBlade has Breeze Js for HTML5, but it looks more as dataservice provider and not support DevForce services.
You might be asking whether BreezeJS offers a mechanism for handling arbitrary service calls between the client and the Web API running on the server ... in the manner of the DevForce "invokeServerMethod".
BreezeJS does not . The DevForce "invokeServerMethod" is helpful when you need to talk to the server for non-data reasons. You don't have to open and secure your own channel; instead you can share the DevForce secure data channel between client and server. It's also a convenient way to sent a package of entities. Setting up your own independent channel is not much fun.
But writing and communicating with a Web API service endpoint is much easier. Our thought is that you can manage your non-data communications quite well without the help of the BreezeJS EntityManager. So we don't see the need to implement the equivalent of "invokeServerMethod"
However, perhaps you have a scenario that would cause us to reconsider. We'd love to learn more.
Breeze doesn't integrate with DevForce today. I'd recommend adding the request to the Breeze UserVoice site. The Breeze team uses UserVoice to judge interest when incorporating new features.
A quick look shows me that there is already one DevForce related suggestion there: Support for DevForce models.
