||
## Installation | ||
|
||
Clone the Github repository, then add all files in *src* to your Qt project, by including *src/src.pri*. | ||
|
||
## Basic Usage | ||
|
||
This example assumes a hypothetical Twitter client that will post tweets. Twitter is using OAuth 1.0. | ||
|
||
### Setup | ||
|
||
Include the required header files, and have some member variables that will be used for authentication and sending requests: | ||
|
||
#include "o1twitter.h" | ||
#include "o1requestor.h" | ||
O1Twitter *o1; | ||
|
||
### Initialization | ||
|
||
Instantiate one of the authenticator classes, like O1Twitter, set your application ID and application secret, and install the signal handlers: | ||
|
||
o1 = new O1Twitter(this); | ||
o1->setClientId(MY_CLIENT_ID); | ||
o1->setClientSecret(MY_CLIENT_SECRET); | ||
connect(o1, SIGNAL(linkedChanged()), this, SLOT(onLinkedChanged())); | ||
connect(o1, SIGNAL(linkingFailed()), this, SLOT(onLinkingFailed())); | ||
connect(o1, SIGNAL(linkingSucceeded()), this, SLOT(onLinkingSucceeded())); | ||
connect(o1, SIGNAL(openBrowser(QUrl)), this, SLOT(onOpenBrowser(QUrl))); | ||
connect(o1, SIGNAL(closeBrowser()), this, SLOT(onCloseBrowser())); | ||
|
||
**Note:** For browserless Twitter authentication, you can use the OXTwitter specialized class which can do Twitter XAuth. You will need to additionally provide your Twitter login credentials (username & password) before calling *link()*. | ||
|
||
### Handling Signals | ||
|
||
O2 is an asynchronous library. It will send signals at various stages of authentication and request processing. | ||
|
||
To handle these signals, implement the following slots in your code: | ||
|
||
void onLinkedChanged() { | ||
// Linking (login) state has changed. | ||
// Use o1->linked() to get the actual state | ||
} | ||
|
||
void onLinkingFailed() { | ||
// Login has failed | ||
} | ||
|
||
void onLinkingSucceeded() { | ||
// Login has succeeded | ||
} | ||
|
||
void onOpenBrowser(const QUrl *url) { | ||
// Open a web browser or a web view with the given URL. | ||
// The user will interact with this browser window to | ||
// enter login name, password, and authorize your application | ||
// to access the Twitter account | ||
} | ||
|
||
void onCloseBrowser() { | ||
// Close the browser window opened in openBrowser() | ||
} | ||
|
||
### Logging In | ||
|
||
To log in (e.g. to link your application to the OAuth service), call the link() method: | ||
|
||
o1->link(); | ||
|
||
This initiates the authentication sequence. Your signal handlers above will be called at various stages. Lastly, if linking succeeds, onLinkingSucceeded() will be called. | ||
|
||
### Logging Out | ||
|
||
To log out, call the unlink() method: | ||
|
||
o1->unlink(); | ||
|
||
Logging out always succeeds, and requires no user interaction. | ||
|
||
### Sending Authenticated Requests | ||
|
||
Once linked, you can start sending authenticated requests to the service. We start with a simple example of sending a text-only tweet or as it's known in Twitter docs, a 'status update'. | ||
|
||
First we need a Qt network manager and an O1 requestor object: | ||
|
||
QNetworkAccessManager *manager = new QNetworkAccessManager(this); | ||
O1Requestor *requestor = new O1Requestor(manager, o1, this); | ||
|
||
Next, create parameters for posting the update: | ||
|
||
QByteArray paramName("status"); | ||
QByteArray tweetText("My first tweet!"); | ||
|
||
QList<O1RequestParameter> requestParams = QList<O1RequestParameter>(); | ||
requestParams << O1RequestParameter(paramName, tweetText); | ||
|
||
QByteArray postData = O1::createQueryParams(requestParams); | ||
|
||
// Using Twitter's REST API ver 1.1 | ||
QUrl url = QUrl("https://api.twitter.com/1.1/statuses/update.json"); | ||
|
||
QNetworkRequest request(url); | ||
request.setHeader(QNetworkRequest::ContentTypeHeader, O2_MIME_TYPE_XFORM); | ||
|
||
Finally we authenticate and send the request using the O1 requestor object: | ||
|
||
QNetworkReply *reply = requestor->post(request, reqestParams, postData); | ||
|
||
Continuing with the example, we will now send a tweet containing an image as well as a message. | ||
|
||
We create an HTTP request containing the image and the message, in the format specified by Twitter: | ||
|
||
QString imagePath("/tmp/image.jpg"); | ||
QString message("My tweet with an image!"); | ||
|
||
QFileInfo fileInfo(imagePath); | ||
QFile file(imagePath); | ||
file.open(QIODevice::ReadOnly); | ||
|
||
QString boundary("7d44e178b0439"); | ||
QByteArray data(QString("--" + boundary + "\r\n").toAscii()); | ||
data += "Content-Disposition: form-data; name=\"media[]\"; filename=\"" + fileInfo.fileName() + "\"\r\n"; | ||
data += "Content-Transfer-Encoding: binary\r\n"; | ||
data += "Content-Type: application/octet-stream\r\n\r\n"; | ||
data += file.readAll(); | ||
file.close(); | ||
data += QString("\r\n--") + boundary + "\r\n"; | ||
data += "Content-Disposition: form-data; name=\"status\"\r\n"; | ||
data += "Content-Transfer-Encoding: binary\r\n"; | ||
data += "Content-Type: text/plain; charset=utf-8\r\n\r\n"; | ||
data += message.toUtf8(); | ||
data += QString("\r\n--") + boundary + "--\r\n"; | ||
|
||
QNetworkRequest request; | ||
// Using Twitter's REST API ver 1.1 | ||
request.setUrl(QUrl("https://api.twitter.com/1.1/statuses/update_with_media.json")); | ||
request.setHeader(QNetworkRequest::ContentTypeHeader, "multipart/form-data; boundary=" + boundary); | ||
request.setHeader(QNetworkRequest::ContentLengthHeader, data.length()); | ||
|
||
QNetworkReply *reply = requestor->post(request, QList<O1RequestParameter>(), data); | ||
|
||
That's it. Tweets using the O2 library! | ||
|
||
### Storing OAuth Tokens | ||
|
||
O2 provides simple storage classes for writing OAuth tokens in a peristent location. Currently, a QSettings based backing store **O2SettingsStore** is provided in O2. O2SettingsStore keeps all token values in an encrypted form. You have to specify the encryption key to use while constructing the object: | ||
|
||
O0SettingsStore settings = new O0SettingsStore("myencryptionkey"); | ||
// Set the store before starting OAuth, i.e before calling link() | ||
o1->setStore(settings); | ||
... | ||
|
||
You can also create it with your customized QSettings object. O2SettingsStore will then use that QSettings object for storing the tokens: | ||
|
||
O0SettingsStore settings = new O0SettingsStore(mySettingsObject, "myencryptionkey"); | ||
|
||
Once set, O2SettingsStore takes ownership of the QSettings object. | ||
|
||
**Note:** If you do not specify a storage object to use, O2 will create one by default (which QSettings based), and use it. In such a case, a default encryption key is used for encrypting the data. | ||
|
||
### Extra OAuth Tokens | ||
|
||
Some OAuth service providers provide additional information in the access token response. Eg: Twitter returns 2 additional tokens in it's access token response - *screen_name* and *user_id*. | ||
|
||
O2 provides all such tokens via the property - *extraTokens*. You can query this property after a successful OAuth exchange, i.e after the *linkingSucceeded()* signal has been emitted. | ||
|
||
## More Examples | ||
|
||
The *examples* folder contains complete example applications: | ||
|
||
Name | Description | ||
:-- | :-- | ||
facebookdemo | Command line application authenticating with Facebook | ||
sialis | QT Quick Twitter client using OAuth 1 | ||
twitterdemo | Command line client for authenticating with Twitter and posting status updates. Uses OAuth 1 or Twitter XAuth | ||
|
||
## Change Log | ||
|
||
### 0.1.0 | ||
|
||
* Persist the extra tokens, too | ||
* Add Qt Quick Twitter client example | ||
