This is a library for using Twitter API from C++

Features

you can use these endpoint

• statuses/destroy/:id
• statuses/retweet/:id
• statuses/unretweet/:id
• statuses/user_timeline
• favorites/create
• favorites/destroy
• media/upload(support: jpg, jpeg, png, gif, mp4)
• direct_messages/events/new (message_create)

Dependency

• libcurl(openssl version)
• libssl

Installation

Ubuntu

# apt install clang cmake git libboost-dev libcurl4-openssl-dev libssl-dev ninja-build
$ git clone https://github.com/koron0902/CocoaTweet
$ cd CocoaTweet
$ mkdir build
$ cd build
$ cmake .. -G Ninja
$ ninja

macOS

$ brew install cmake curl git ninja openssl pkg-config
$ git clone https://github.com/koron0902/CocoaTweet
$ cd CocoaTweet
$ mkdir build
$ cd build
$ cmake .. -G ninja -DOPENSSL_ROOT_DIR=<path/to/openssl/install> # CANNOT detect libssl automatically with homebrew and cmake bug
$ ninja

Windows

• Get MinGW32 from here(start download automatically at open link)
• Install mingw32-base-bin and mingw32-gcc-g+-bin via MinGW32
• Add PATH in System Environment
• Get libcurl-32bit and OpenSSL-32bit from here
• Get ninja from here and add PATH(Optional, but build faster)

and then....

$ git clone https://github.com/koron0902/CocoaTweet
$ cd CocoaTweet
$ mkdir build
$ cd build

// if install ninja
$ cmake .. -G Ninja -DOPENSSL_ROOT_DIR=<path/to/openssl/install> -DCURL_ROOT_DIR=<path/to/curl/install> -DCMAKE_CXX_COMPILER=mingw32-g++ -DCMAKE_C_COMPILER=mingw32-gcc -DCMAKE_MAKE_PROGRAM=ninja 
$ ninja

// if NOT install ninja
$ cmake .. -G "MinGW Makefiles" -DOPENSSL_ROOT_DIR=<path/to/openssl/install> -DCURL_ROOT_DIR=<path/to/curl/install> 
$ mingw32-make

How

API Key Registration

1.Write Key into code

write api key into code and create Key object use it.

#include "cocoatweet/authentication/key.h"

auto consumerKey       = "your consumer key";
auto consumerSecret    = "your consumer secret";
auto accessToken       = "your access token";
auto accessTokenSecret = "your access token secret";

CocoaTweet::Authentication::Key key(consumerKey, consumerSecret, accessToken, accessTokenSecret);

2. Load Key from JSON file

prepare file which written 'api-key' with json format.

{
  "consumer_key" : "your consumer key",
  "consumer_secret" : "your consumer secret",
  "access_token" : "your access token",
  "access_token_secret" : "your access token secret"
}

then you can load api key from json file.

#include "cocoatweet/authentication/key.h"

CocoaTweet::Authentication::Key key = CocoaTweet::Authentication::Key::fromJsonFile("api_key.json");

3. Authenticate with API call

※ consumer key, consumer secret are needed. in this case, get access token with api call.

CocoaTweet::API::API api(key);

auto oAuthToken = api.oauth1().requestToken("oob");
const auto signInUrl = api.oauth1().authorize(oAuthToken);
std::cout << "signin : " << signInUrl << std::endl;
std::string pin = "";
std::cout << "pincode : ";
std::cin >> pin;

const auto validOAuthToken = api.oauth1().accessToken(oAuthToken, pin);
key.accessToken(validOAuthToken.oauthToken());
key.accessTokenSecret(validOAuthToken.oauthTokenSecret());
api.swapKey(key);

4. Get BearerToken with AIP call

if you want to call Twitter API using Bearer Token; OAuth2, you can do.

CocoaTweet::API::API api(key);
auto bearerToken = api.oauth2().token();
key.bearerToken(bearerToken);
key.authType(CocoaTweet::Authentication::Key::AUTH_TYPE::OAUTH2);
api.swapKey(key);

After call it, always use Bearer Token to access API which kinds of GET method.
no affect to POST method.
then, if you use this, and ONLY use kind of GET API, you DO NOT need acess token.

Generate API object

generating API object with Key.
this object is API entry point.

#include "cocoatweet/api/api.h"

CocoaTweet::API::API api(key);

Use API

// Post a tweet
api.status().update("Hello, World!!\nTweet from Cocoa Twitter Library");

// Upload a media
auto media1 = api.media().Upload("path/to/file/image.jpeg");
auto media2 = api.media().Upload("path/to/file/image2.png");
api.status().update("Upload media from Cocoa Twitter Library", std::vector<std::string>{media1.id(), media2.id()});

// Retweet a tweet
api.status().retweet("tweet id");

// un RT a tweet
api.status().unretweet("tweet id")

// Delete a tweet
api.status().destroy("tweet id");

// Fav. a tweet
api.favorite().create("tweet id");

// un Fav. a tweet
api.favorite().destroy("tweet id");

// get a timeline with screen name
auto timeline = api.status().userTimeline("milkcocoa0902");

// send a direct message
// you cau get recipient_id using https://idtwi.com/
api.directMessage().messageCreate("<recipient_id>", "Sent message using Cocoa Twitter Library");
