I am using csharp code to generate the access token but this token is not working when i try to join a call

[fullstack10]

[Hoang-Minh]

I also run into the same issue. Any help ? I'm using the code below to generate my token:

AccessToken token = new AccessToken(_appId, _appCertificate, _channelName, _uid, _ts, _salt);
token.message.ts = _ts;
token.message.salt = _salt;
token.addPrivilege(Privileges.kJoinChannel, _expiredTs);

string result = token.build();

[Hoang-Minh]

The c# code is broken. I was able to generate the token by using node js. Please fix the package to generate code in c#. Thank you !!!

[fullstack10]

i just prefix variable values in accesstoken.cs class which is mentioned below ,

    private uint _ts = 1111111;
    private uint _salt = 1;
    private uint _expiredTs = 1446455471;
    
    and while calling    AccessToken token = new AccessToken(appId, appCertificate, channelName, uid, ts, salt);

i am passing uid = "0"; and its working

string uid = "0"; means you can use the same token for connecting a video call specific uid means you need two / more different access token to connect video call

[Hoang-Minh]

Thanks @fullstack10 . Its not working for me even if I passed uid = "0". This is my generated token when passing uid = "0". However, when I used it for the demo (https://github.com/AgoraIO-Community/AgoraWebSDK-NG) it is not working. 0063fb869e0755144ae9cd4a714201cf921IAA2bQNquudi3rrKnZFQfe6VdO/mPvqiZPHswcCB1DZuJlsFw2wh39v0EAABAAAAR/QQAAEAAQCvKDdW

What does your token look like @fullstack10 ? Thank you

[fullstack10]

hi @Hoang-Minh , i am using https://github.com/AgoraIO/Tools/tree/master/DynamicKey/AgoraDynamicKey/csharp this code , and my token is 006970CA35de60c44645bbae8a215061b33IADNg9bfcUDIC1Qs1EedxluwYPEhU8Z66b8WHMWwqz0L9wx+f9gh39v0EAABAAAAR/QQAAEAAQCvKDdW

[Hoang-Minh]

@fullstack10 Have you tried to use your key with the demo ? https://webdemo.agora.io/agora-web-showcase/examples/Agora-Web-Tutorial-1to1-Web/

For me, key cannot be used to join if using csharp. However, if I use the key generated from nodejs then it's working for me.

[fullstack10]

Yes I tried and now i am using this in my live project and its working

@fullstack10 hmmm, that is so weird. It does not work for me at all. Its giving me this error in c#

@yoreland Can you help me out please ? Thank you

[fullstack10]

Hi can you please provide me your appid and app secret so i will create a token for you and tested with my code if anything different then i will update you . On Mon, 15 Nov 2021 at 11:48 PM, Hoang Minh @.***> wrote:

I think Github censors your email. Anyway, here is my agora info:

AppId: 3fb869e0755144ae9cd4a714201cf921
AppCertificate: edb6e4236aec4bf7a181898255dec8da

Thank you

[fullstack10]

hi , just replace below method in accesstoken.cs class. then it starts working.

accesstoken.cs

public void addPrivilege(Privileges kJoinChannel, uint expiredTs) { // this.message.messages.Add((ushort)kJoinChannel, expiredTs); }

Hmmm, commenting that part of code out will take out the privilege and expire time for your token. It will have impact on the generated token. I thought you said that the code is working for you without commenting that out ? Am I correct ? Thank you

[fullstack10]

I tried with expiration time as well but its not working and then i did this but the token which we generated from this code with comment this line it will expire in 24 hours so its work for me.

Got it. Thank you @fullstack10

[Hoang-Minh]

@fullstack10 FYI, my token is still not working even though I have commented the code that you said. @yoreland : Are not not supporting/maintaining this package anymore ? I've been asking for help for more than a week and I have not got any response yet.

[fullstack10]

I will send you a code just use that and try again.

Thank you @fullstack10

[Hoang-Minh]

@fullstack10 I figured out how to generate a token with expiration time. The problem lies in the _ts and _salt value. We need not to pass them in to the access token constructor. Below is my snippet code:

      ` var expireTime = 3600;
        var test = new DateTimeOffset(DateTime.UtcNow).ToUnixTimeSeconds();
        _expiredTs = (uint)(test + expireTime);

        string expected = "006970CA35de60c44645bbae8a215061b33IACV0fZUBw+72cVoL9eyGGh3Q6Poi8bgjwVLnyKSJyOXR7dIfRBXoFHlEAABAAAAR/QQAAEAAQCvKDdW";
        
        AccessToken token = new AccessToken(_appId, _appCertificate, _channelName, _uid);

        token.addPrivilege(Privileges.kJoinChannel, _expiredTs);
        string result = token.build();
        Assert.Equal(expected, result);`

[fullstack10]

Great , thank you so much now do you need the c# code. On Fri, 19 Nov 2021 at 1:27 PM, Hoang Minh @.***> wrote:

Hi @ken39arg,

I getting problem of expiring time.

My code for generating the token in the dotnet, below is my code.

public AgoraResponseDto testGenerateDynamicKey(AgoraRequestDto agoraRequestDto)
        {
            AgoraResponseDto agoraResponseTest = new AgoraResponseDto();

            var expireTime = 3600;
            var test = new DateTimeOffset(DateTime.UtcNow).ToUnixTimeSeconds();
             _expiredTs = (uint)(test + expireTime);


            //string expected = "006970CA35de60c44645bbae8a215061b33IACV0fZUBw+72cVoL9eyGGh3Q6Poi8bgjwVLnyKSJyOXR7dIfRBXoFHlEAABAAAAR/QQAAEAAQCvKDdW";
            AccessToken token = new AccessToken(_appId, _appCertificate, _channelName, _uid, _ts, _salt);
            token.message.ts = _ts;
            token.message.salt = _salt;
            token.addPrivilege(Privileges.kJoinChannel, _expiredTs);

            string result = token.build();
            agoraResponseTest.AppCertificate = _appCertificate;
            agoraResponseTest.AppId = _appId;
            agoraResponseTest.Channel = _channelName;
            agoraResponseTest.Token = result;
            return agoraResponseTest;
        }

and the response is :

{
  "channel": "123456789",
  "appId": "43608641637444738faddaf9f89c62ed",
