Curlite

Curlite is developed as a lightweight wrapper over cURL library with the following points in mind:

• Support of C++11 features
• Type safety of curl options
• Ease-of-use
• No external dependencies (except libcurl)

The project is in development stage. Currently only Easy interface is implemented.

Examples

Example 1. Write web page source to stdout

try
{
    curlite::Easy easy;
    easy.set( CURLOPT_URL, "http://example.com" );
    easy.set( CURLOPT_FOLLOWLOCATION, true );

    // start download
    std::cout << easy;
}
catch( std::exception &e ) {
    std::cerr << "Got an exception: " << e.what() << std::endl;
}

or just use curlite::download() method:

try
{    
    curlite::download( "http://example.com", std::cout, true );
}
catch( std::exception &e ) {
    std::cerr << "Got an exception: " << e.what() << std::endl;
}

Example 2. Upload file to remote FTP server and show transfer time

try
{
    curlite::Easy easy;
    easy.set( CURLOPT_URL, "ftp://example.com/file.txt" );
    easy.set( CURLOPT_USERNAME, "username" );
    easy.set( CURLOPT_PASSWORD, "password" );
    easy.set( CURLOPT_UPLOAD, true );

    // open input file stream
    std::ifstream ifs( "file.txt", std::ios::binary );

    // start upload
    ifs >> easy;
    
    double totalSecs = easy.getInfo<double>( CURLINFO_TOTAL_TIME );
    std::cout << "Upload time: " << totalSecs << " s" << std::endl;
}
catch( std::exception &e ) {
    std::cerr << "Got an exception: " << e.what() << std::endl;
    return 1;
}

And the same with curlite::upload() method:

try
{
    std::ifstream ifs( "file.txt", std::ios::binary );  
    auto easy = curlite::upload( ifs, "ftp://example.com/file.txt", "username", "password" );
    
    double totalSecs = easy.getInfo<double>( CURLINFO_TOTAL_TIME );
    std::cout << "Upload time: " << totalSecs << " s" << std::endl;
}
catch( std::exception &e ) {
    std::cerr << "Got an exception: " << e.what() << std::endl;
}

FAQ

What is minimum supported libcurl version?

Curlite should work with libcurl 7.32 and later.

What compilers are supported?

Curlite requires from compiler a basic support of C++11. The minimum supported version are: g++ 4.6, clang 3.2, VS 2010 and later.

What is the difference between Easy::onWrite() and Easy::onWrite_()?

The latter (with underscore) sets simplified handler, while the first sets usual cURL handler.

Are curlite objects thread-safe?

No, they are not.

Why the hell would anyone use libcurl, when there is Qt / POCO / cpp-netlib / urdl / ...

I like those libraries, but in some cases libcurl is the best choice: it's easy, stable and supports a huge number of protocols. Download via HTTPS? - ok. Send email? - no problem.
