Very simple libcurl wrapper in C++

curl-cpp-wrapper

A very simple HTTP client (C++ wrapper for curl). Requires libcurl http://curl.haxx.se

If you are using Visual C++ your also have to install msinttypes (headers are provided in "include" directory).

Usage

Do a GET request:

NetworkClient nc;
nc.doGet("http://google.com/?q=" + nc.urlEncode("Smelly cat"));
std::cout << nc.responseBody();

Do a POST request:

nc.setUrl("https://www.googleapis.com/oauth2/v3/token");
nc.addQueryParam("refresh_token", refreshToken); 
nc.addQueryParam("client_id", clientId); 
nc.addQueryParam("client_secret", clientSecret); 
nc.addQueryParam("grant_type", "refresh_token"); 
nc.doPost();
std::cout << nc.responseBody();

Do a POST request with RAW data:

nc.setUrl("https://www.googleapis.com/oauth2/v3/token");
nc.doPost("param1=value&param=value");

Downloading a file:

NetworkClient nc;
nc.setOutputFile("d:\\image.png"); //only UTF-8 file names are supported on Windows
nc.doGet("http://i.imgur.com/DDf2wbJ.png");

Uploading a file:

#include "NetworkClient.h"
#include "Core/Utils/CoreUtils.h"
NetworkClient nc;
std::string fileName = "c:\\test\\file.txt"; //only UTF-8 file names are supported on Windows
//std::string fileName = IuCoreUtils::SystemLocaleToUtf8(fileName); <-- if you want to upload a file with ANSI filename on Windows
nc.setUrl("http://takebin.com/action");
nc.addQueryParamFile("file", fileName, IuCoreUtils::ExtractFileName(FileName),"");
nc.addQueryParam("fileDesc", "cool file");

nc.doUploadMultipartData();
if ( nc.responseCode() == 200 )  {
		std::cout << nc.responseBody();
}

Do a PUT request:

nc.setMethod("PUT");
nc.setUrl("https://www.googleapis.com/drive/v2/files/" + id);
nc.addQueryHeader("Authorization", "Basic ");
nc.addQueryHeader("Content-Type", "application/json");
std::string postData = "{\"title\" = \"SmellyCat.jpg\"}";
nc.doUpload("", postData);

Uploading a file to FTP:

std::string fileName = "c:\\test\\file.txt";
nc.setUrl("ftp://example.com");
nc.setMethod("PUT");
nc.doUpload(fileName, "");

Using proxy:

nc.setProxy("127.0.0.1", "8888", CURLPROXY_HTTP); // CURLPROXY_HTTP, CURLPROXY_SOCKS4, CURLPROXY_SOCKS4A, CURLPROXY_SOCKS5, CURLPROXY_SOCKS5_HOSTNAME

Custom request header:

nc.addQueryHeader("User-Agent", "Mozilla/5.0");

If you want to use HTTPS, you should compile libcurl with openssl support (you could also use WinSSL on Windows). If you compile libcurl for windows with OpenSSL support (instead of WinSSL), you should put "curl-ca-bundle.crt" file into your application's directory).
