I 'm a newbie to twitter api/twitterizer. I get the following exception for the code shown below. The error occurs when i request access token. Any suggestion on how to fix this??
I downloaded the latest dll(2.3.1) from the twitterizer website.
{"Value cannot be null. Parameter name: String"}
Dim OAuthTokens As New OAuthTokens
Dim accessToken As New Twitterizer.OAuthTokenResponse
accessToken = OAuthUtility.GetAccessToken(ConsumerKey, ConsumerSecretkey, "oauth_token", "oauth_verifier")
thanks
As I said on the forums, the oauth_token and oauth_verifier are given to you in previous steps of the authorization process. Calling the GetAccessToken method is the last step in the process.
Here's an over-simplification of the steps:
1. Get a request token
2. Send/Redirect the user to the authorization/authentication url
3. (The user logs in, grants you access, and Twitter directs them back to your application)
4. Exchange the request token for an access token

Having problem getting security token generated from my server to work properly. I modified the basicLive.js of the demo in AgoraWebSDK-NG to work with my server. I'm using the Golang api provided by Agora to generate the token. Some information:
AppID: ---
App Certificate: ---
channel name: liveshow10
uid: 51495 (I assume Agora does not care about this as long as it is uint32)
token expiration seconds: 3600
generated token: 006cb08a5a2ddc049f79f29d9b52e5909b0IABKKxbI64sFWnkyEICQrL+0DeTsrN9ckKMkDj/oir36aV+tq536WyGcIgCHHmUFHNv6XgQAAQCsl/leAgCsl/leAwCsl/leBACsl/le
But I'm getting bunch of error in the console. I think it boils down to an authorization error the token generated somehow is invalid. Below is the browser console and thanks for any help:
For anyone following along, the issue was related to UID. In the above code the token is generate specifically for UID 51495 but in the Agora Demo, the JoinChannel method passes null as the UID value which tells the SDK to generate its own UID for that user.
When attempting to join a channel with a different UID than the one used to generate the token, you will receive an error.
If you want to generate a token that can be used by any user, you need to set the UID to 0 in the token generation, and then you can use any UID join the channel with this token.
Update: The UID 0 detail can be found in the Token Server API reference within the UID parameter description docs.agora.io/en/video/token_server#api-reference
I have some troubles with getting Access token with grant type authorization code using Robot framework with Oauth2.
We use also a username/password authentication and after give the following parameters we get back our access token:
Grant Type, Callback URL, Auth URL, Access Token URL, Client ID, Client Secret, Scope, State.
I tried with RequestsLibrary and ExtendedRequestsLibrary as well, but no success so far.
Actually I do not know how to add parameters: callback url, auth url, access token url and state.
First try - using RequestsLibrary
Get admin token
&{HEADER_TOKEN}= Create Dictionary Content-Type=${CONTENT_TYPE}
&{DATA_TOKEN}= Create Dictionary token_name=backend_token grant_type=${GRANT_TYPE} redirect_uri =${CALLBACK_URL} auth_url=${AUTH_URL} access_token_url=${ACCESS_TOKEN_URL} client_id=${CLIENT_ID} client_secret=${CLIENT_SECRET} scope=${SCOPE} state=${STATE} username=${USERNAME} ${PASSWORD}
${BACKEND_RESPONSE}= RequestsLibrary.Post Request ${BACKEND_SESSION} /oauth/token data=${DATA_TOKEN} headers=${HEADER_TOKEN}
Log to console ${BACKEND_RESPONSE}
Should Be Equal As Strings ${BACKEND_RESPONSE.status_code} 200
Second try - using ExtendedRequestsLibrary
Get brand new admin token
${SESSION_RESPONSE}= Create Password Oauth2 Session client ${TOKEN_URL} ${CLIENT_ID} ${CLIENT_SECRET} ${USERNAME} ${PASSWORD} base_url=${BASE_URL}
&{HEADER_TOKEN}= Create Dictionary Content-Type=${CONTENT_TYPE}
&{DATA_TOKEN}= Create Dictionary token_name=client grant_type=${GRANT_TYPE} callback_url=${CALLBACK_URL} auth_url=${AUTH_URL} access_token_url=${ACCESS_TOKEN_URL} client_id=${CLIENT_ID} client_secret=${CLIENT_SECRET} scope=${SCOPE} state=${STATE}
${BACKEND_RESPONSE}= ExtendedRequestsLibrary.Post Request client /oauth/token data=${DATA_TOKEN} headers=${HEADER_TOKEN}
Log to console ${BACKEND_RESPONSE}
Should Be Equal As Strings ${BACKEND_RESPONSE.status_code} 200
Log to console ${BACKEND_RESPONSE.status_code}
If you have any idea just let me know.
thx!
using RequestsLibrary try with this approach it should work:-
Create Session baseUri https://xxxxxx.xx.xxx/xxx/xx verify=True
&{params}= Create Dictionary client_id=${client_id} client_secret=${client_secret} grant_type=${grant_type}
&{headers}= Create Dictionary Content-Type=application/json
${resp}= Post Request baseUri /oauth/token none none ${params} ${headers}
Log to Console ${resp.json()['access_token']}
Status Should Be 200 ${resp}
you are passing data=${DATA_TOKEN} as a body in your post request. You need to send it as query params. First parameter will be alias 2nd is uri 3rd is data 4th is Json and 5th is query params so in
Post Request baseUri /oauth/token none none ${params} ${headers}
you will find 3rd and 4th parameter as none. Hope this works
I developed a chrome extension using Rally's WSAPI v2.0, and it basically does the following things:
get user and project, and store them
get current iteration everytime
send a post request to create a workitem
For the THIRD step, I sometimes get error ["Not authorized to perform action: Invalid key"] since end of last month.
[updated]Error can be reproduced everytime if I log in Rally website via SSO before using the extension to send requests via apikey.
What's the best practice to send subsequent requests via apikey in my extension since I can't control end users' habits?
I did see some similar posts but none of them is helpful... and in case it helps:
I'm adding ZSESSIONID:apikey in my request header, instead of user /
password to authenticate, so I believe no security token is needed
(https://comm.support.ca.com/kb/api-key-and-oauth-client-faq/kb000011568)
url starts with https://rally1.rallydev.com/slm/webservice/v2.0/
issue is fixed after clearing cookies for
https://rally1.rallydev.com/, but somehow it appears again some time
later
I checked the cookie when the issue was reproduced, and found one with name of ZSESSIONID and its value became something else rather than the apikey. Not sure if that matters though...
code for request:
function initXHR(method, url, apikey, cbFunc) {
let httpRequest = new XMLHttpRequest();
...
httpRequest.open(method, url);
httpRequest.setRequestHeader('Content-Type', ' application\/json');
httpRequest.setRequestHeader('Accept', ' application\/json');
httpRequest.setRequestHeader('ZSESSIONID', apikey);
httpRequest.onreadystatechange = function() {
...
};
return httpRequest;
}
...
usReq = initXHR ('POST', baseURL+'hierarchicalrequirement/create', apikey, function(){...});
Anyone has any idea / suggestion? Thanks a million!
I've seen this error when the API key had both read-only and full-access grants configured. I would start by making sure your key only has the full-access grant.
I am getting the following exception whenever i try to fetch defects from rally:

What intrigues me most is the code works perfectly fine on few machines and throws the above exception on few.
code snippet :
RallyRestApi restApi =
new RallyRestApi(new URI("http://rally1.rallydev.com"),apiKey);
QueryRequest queryRequest = new QueryRequest("defects");
queryRequest.setFetch(new Fetch("Project","FormattedID","Release"));
QueryFilter filter1 = new QueryFilter("FormattedID", "=", defetctID);
QueryResponse queryResponse1 = restApi.query(queryRequest);
Try a curl command to read the same defect using the same apiKey (in zsessionid header) on the same machine from which your java code fails.
curl --header "ZSESSIONID: _abc123" "https://rally1.rallydev.com/slm/webservice/v2.0/defect/123456789"
At least you will know if this is specific to java or not. Yes, it is strange that it fails on some machines and works on others, but the timing of those tests is not obvious from your post, and I wonder if this has anything to do with the underlying user credentials. (A user gets disabled for a period of time after a number of unsuccessful attempts). I am not positive that this is the issue you experience but I have seen when expired password caused the exact same error. API Keys are tied to a user, so when a user's password is expired, or when a user is inactivated (disabled) the same permissions(or the lack of them) is reflected in the key. For example, a user did not know that the password was expired because in the Rally UI they used SSO authentiation, but in the code they used either username/password or APIKey since the toolkit does not support SSO at this point. A 401 error would be more helpful, but instead a malformed JSON is generated.
Here's my current operations:
1./ User accepts app and the app callback stores the oauth_token and oauth_token_secret into the database (as access_token and access_token_secret).
2./ We use a cli script to handle autoposting to twitter. We load the twitter oauth object as follows:
public function post()
{
$consumerKey = $this->getConsumerKey();
$consumerSecret = $this->getConsumerSecret();
$accessToken = $this->getAccessToken();
$accessSecret = $this->getAccessSecret();
$twitteroauth = new TwitterOAuth($consumerKey,$consumerSecret,$accessToken,$accessSecret);
$message = $this->getPostMessage();
$result = $twitteroauth->post('statuses/update', array('status' =>$message));
$this->log($result);
}
Now this assumes we are using the API consumer key and secret assigned to the app and the user's stored access tokens.
The result we are getting is:
Invalid or expired token
I don't quite understand why we are receiving this. We are using the access token and access token secret provided to us by twitter.
I did notice that there is a GET parameter oauth_verifier. This isn't something we need to be using somewhere?
In any case, I'm not quite sure whats wrong here.
Do I need to log in or something before doing posting?
your code is correct.
The problem is that the library's Util.urlParameterParse() method is broken.
