Hello,
I've picked up a web design project, and I would love to use
vibe.d/dlang. I need to use oauth to search on a number of web
api's, such as searching for Twitter tweets.
I tried using Adam's oauth (Thanks!). However, it doesn't
appear support the validation needed for searching Twitter.
https://github.com/adamdruppe/arsd/blob/master/oauth.d
Now I'm looking at std.net.curl, and this is my thought: is
HTTP.addRequestHeader(key, val) able to set the oauth
authentication headers? It would look a bit odd, but if
something like this works, then it wouldn't be difficult to
code for each set of headers specifically:
auto client = HTTP("https://api.twitter.com";); // not sure
if https should be set here or somewhere else
string bearerUrl = "https://api.twitter.com/oauth2/token";;
client.addRequestHeader("Authorization", "Basic
eHZ6MWV2RlM0d0VFUFRHRUZQSEJvZzpMOHFxOVBaeVJnNmllS0dFS2hab2xHQzB2SldMdzhpRUo4OERSZHlPZw");
client.postData("grant_type=client_credentials");
client.perform();
(The above example is based on Step 2 of this page)
https://dev.twitter.com/oauth/application-only
Of course, the oauth headers look a bit different, but I
imagine it being something like this:
client.addRequestHeader("Authorization", "OAuth2 token:
\"string\", tokensecret: \"string\", appkey, \"string\" ...");
\\ not sure if that's how to escape quotes in dlang
Can I get some guidance on this? I would really like to use
dlang, but I can't afford to be stuck on this for too long. I'd
be happy to try and write a modification of Adam's code, but I
lack experience, so it's a slow process for me.
I'd also be happy to write up little tutorials/blogposts about
how I accomplish various tasks.
Thanks,
You can use vibe.d to send requests rather than going the
lowlevel curl library.
Check out the requestHTTP method [1]
From code I've written in the past, your setup looks correct.
This is some vibe.d code I've used to get a refresh token from
Youtube (I know it's different from twitter, but the idea is the
same)
YoutubeToken is a local struct that contains the access_token we
need to perform searches/post videos etc in any subsequent
requests.
/**
* Returns a new YoutubeToken
*/
public YoutubeToken getRefreshToken(){
string url = "https://accounts.google.com/o/oauth2/token";;
string postBody =
"client_id=$CLIENT_ID$&client_secret=$CLIENT_SECRET$&refresh_token=$REFRESH_TOKEN$&grant_type=$GRANT_TYPE$"
.replaceMap(
[
"$CLIENT_ID$" : credentials.clientID,
"$CLIENT_SECRET$" : credentials.clientSecret,
"$REFRESH_TOKEN$" : credentials.refreshToken,
"$GRANT_TYPE$" : "refresh_token"
]
);
logInfo("Getting new refresh token with URL: %s and postBody:
%s", url, postBody);
auto response = requestHTTP(url,
(scope req){
req.method = HTTPMethod.POST;
req.contentType = "application/x-www-form-urlencoded";
req.writeBody(cast(ubyte[])postBody);
}).bodyReader.readAllUTF8().parseJsonString;
return YoutubeToken(response["access_token"].get!string,
response["expires_in"].get!long,
response["token_type"].get!string );
}
