I'm using DataServices and OData protocol. I need to generate HTTP Get, Post, Delete, and Update from a C++ application. How I can do this? What is the easiest way?
Try cURL. check out this SO post. Perform a simple HTTP request using C++ / Boost via a proxy?
Boost.Asio. There's an example of a simple HTTP client (with a GET request).
The POCO library is another alternative to cURL
You can use MS stuff: Wininet or WinHTTP.
Adding to this old post.
Beast is a cross-platform, header-only, modern C++11 library built on Boost.Asio that provides implementations of the HTTP and WebSocket protocols.
The project is under evaluation to be included in Boost, so it may be worth looking at it.

I'm rewriting a Java project in C++ where I used okhttp. Is there a similar lib to easily send GET/POST requests? I tried to setup cURLpp but can't find a guide to compile it.
You can try to use cpp-netlib based on C++11
It's pretty much the tittle.
Im not expecting the whole code to just copy and paste (but feel free to do it). Im just having difficulties to find some data related. If someone knows how to do it, please post some hints, article links, specific words to make some research on it.
Thank you.
As Christian mentioned in his comment, your problem can be solved by implementing an HTTP client that parses JSON responses, independently of the technology used by your server. To do this in C++, I would refer you to the following resources:
High-level library for C++ HTTP client.
libcurl (lower level library for HTTP requests).
RapidJSON library to parse the responses you will get from your server (see this benchmark for a comparison of JSON parsing libraries).
If your C++ application uses a framework such as Qt, it likely includes facilities for requests (e.g. Qt HTTP example).
On the server side, you will have to define HTTP endpoints that return the data you are interested in, encoded as JSON. The beginning of this tutorial shows an easy way to do that.

I am new to boost lib. I need a client program which will communicate with the server even in proxy environment also. I have tried with the poco lib,in that i got struck at creation of web socket after Handshake. After i am trying with this boost package and i have downloaded a sample chat client program from the boost examples.In that i don't know where to set proxy requirements. I searched in the all .cpp file inside the boost package. But i didn't understand any thing.
Can any body plz help me whether it is possible to do client communication in proxy environment with this.if it is possible tell me how.if not with this,please suggest any possible way.
Thanks,
vvk.
Boost Asio does not have proxy support.
I'd use libcurl for this myself. Libcurl has some integrations with Boost Asio floating around on github.
There's also CppNetlib which (undoubtedly) will have proxy support, and is integrated with Boost Library like Asio is (although it's not a part of the boost library distribution like Asio is).
Lastly, there's some hints on getting "manual" proxying started using just Boost Asio here:
how to add proxy support to boost::asio?
Although this will leave you implementing your own authentication too :/
I am working on a project where I need to communicate with a server using a network library in C++. Currently im using POCO/Net
Is there any C++ library that has support for response caching, authentication, HTTP and HTTPS similar to the Java version?
Greatful for help!
wwwlib seems to provide the kind of persistant cache you are after and is http 1.1 compliant according to W3lib. I have not yet tried it though, it seems very low level in comparison to POCO. Someone else might have a simpler library...
I'm quite a newbie with Boost, and my only experience of surfing though a proxy using a library is using .NET (that is really convenient for that purpose). I'm now trying to perform a simple HTTP request through a HTTP proxy.
Is there a tidy way to do it using boost directly?
My proxy use a NTLM authentification.
No, Boost provides neither an HTTP client nor a way to interface with proxies. You would necessarily have to implement those features yourself.
To be clear, yes, it is possible to implement an HTTP client using Boost.Asio. But implementing a client that can reliably talk through a proxy is significantly more complex, and Asio does not provide any support for that beyond the low-level socket itself. It certainly does not include the framework for performing NTLM authentication, which may prove difficult to get right.
More complex libraries like cURL provide that support.
