Hello please i have problem with markalive i have markalive falsr but iam permanently active on fb by my bot so markalive not working i think

Error information:

{"Error when sending request: Got InternalServerError response"}

Iam able to login with with no authentication and everything is working fine. I turned on 2 step authentication and now its not working. Im using this sample project with no code changes. The Inputbox comes up asking to enter my code but I never get the code to my phone. If I login from the browser it works fine. I get the sms and I can login. But for the app it does not work. I tried both uwp and wpf. The only thing that happens is that Facebook sees a login request and blocks that request. There is no sms being sent. It only gets blocked. Seems like sms 2 step is not being initiated from the app. If i use anything else such as browser or Facebook Messenger I get the sms code and I can login. Please can you help with this? Everything else is working great just this one last thing. Thank you. Here is the error I get from facebook when I check from the browser ===

I want to perform a validation before list all my contacts and check which of my contacts are currently online.

Hi! I've recently started using your library in my project. Unluckily, sending images doesn't work for me.

Code (FBClient is the the same as in the example):

using System;
using System.IO;
using System.Threading.Tasks;
using fbchat_sharp.API;

namespace bot
{
    class Program
    {
        private static readonly FBClient client = new FBClient();
        static async Task Main()
        {
            Console.WriteLine("fbchat-sharp test");
            await client.DoLogin("login", "password");
            using (FileStream stream = File.OpenRead("image.png"))
            {
                await client.sendLocalImage("image.png", stream, null, "0000", ThreadType.GROUP);
            }
        }
    }
}

Exception:

I don't know if it's a mistake in my code or the library just doesn't work properly. If it's my mistake, I'd be thankful for pointing it out!

I'm compiling the latest version of the library from source, I'm not using the NuGet package.

Client client = new Client();
await client.doLogin(login, password);

throws error

in fbchat (python) same loggining info passes fine

It would be interesting to add a solution folder in the project with some examples as well as we have in fbchat, such as EchoBot.

FB_User.color always returns null and I think it should be ThreadColor not Stringand if it should be a String then it must returns the color hex code

Hello please its will be possible to make simple project for you quick guide to your repository?
Thanks in advance for your answer

Hello please i have problem with onMessage event.
This event stop working after few hours without any error i think its stop listening. and i dont know how to print debug messages :( to console and better to file

Hey!

Does this library continue to function?

I can't log in, but email and password are correct.
I have done all as you, also checked your examples and they also don't work.
I installed Gave.Libs.Fbchat.

Use Visual Studio 2017.

I tested library, found Null reference exception in company chats (quick replies) - see file Message.cs, line 281:

var quick_replies = JToken.Parse(data.get("platform_xmd_encoded")?.Value<string>()).get("quick_replies");
if (quick_replies.Type == JTokenType.Array)
    rtn.quick_replies = quick_replies.Select((q) => FB_QuickReply.graphql_to_quick_reply(q)).ToList();
else
    rtn.quick_replies = new List<FB_QuickReply>() { FB_QuickReply.graphql_to_quick_reply(quick_replies) };

In two company chats I received quick_replies == null.
Propose small fix:

                var quick_replies = JToken.Parse(data.get("platform_xmd_encoded")?.Value<string>()).get("quick_replies");
                if (quick_replies != null)
                {
                    if (quick_replies.Type == JTokenType.Array)
                        rtn.quick_replies = quick_replies.Select((q) => FB_QuickReply.graphql_to_quick_reply(q)).ToList();
                    else
                        rtn.quick_replies = new List<FB_QuickReply>() { FB_QuickReply.graphql_to_quick_reply(quick_replies) };
                }

This error message happend from Facebook.

"We want to make sure your account is secure
We have recently noticed an unusual activity on your account. We have disconnected you for your safety and that of other users.
To re-access your account, we will guide you through a few steps."

I read it might be cause of creating too much session, so I used this code:

        `bool islogged = false;
        ConstVars.client = new FBClient_Cookies();
        var client = new FBClient_Cookies();
        islogged =  await ConstVars.client.TryLogin();
        if (islogged)
        {
            Console.WriteLine("got last session.");
        }
        else
        {
            Console.WriteLine("new session.");
            await ConstVars.client.doLogin("mail", "pass", 1);
        }
        await ConstVars.client.WriteCookiesAsync();`

It always returns "new session".
Any idea about how to process ?

I cant login. Session is null. Is there something i dont understand?

I have problems doing login. I do type the correct username/password, but still login is not succesful - boolean from DoLogin is false and no details seem available?
I have an old NodeJS application using facebook-chat-api and with this I can login.

I'm using this under dotnet core (2.1).

Any ideas?

Whenever I try to write a chat message facebook locks my account and forces me to change my password. With this great app my code is simple:

MessengerClient client = new FBClient_Simple();
var result = client.DoLogin(Email, Password).Result;
var group = client.searchForGroups(Group).Result;
var msg_uid = client.SendMessage(Message, group[0].uid, ThreadType.GROUP).Result;
r = client.DoLogout().Result;

Does anyone else have this problem? Is there a workaround?

Cannot login in when using release mode in UWP app (in Debug it works) and shows this error

Hello i using this app for logging my messages but now not working onMessage on netcore logging is without problem but onmessage not works :(

Is there any way to retrieve data for a page (threads, messages, etc)?
I was looking for any options on the doLogin method to input the page ID but couldn't found anything.😊Thanks

By the way, amazing library, it's just very hard to find, once this becomes more visible in google im sure it will be huge.

Is wrong, because throws errors.

Greetings. Earlier this year my app worked perfectly, but now it hangs on these two methods indefinitely.

Hello everyone. I have another error I hope you can help to fix. When building this app for UWP I get a certification error. Im building only for x64 in release mode. Here is the error.

Binary analyzer
Error Found: The binary analyzer test detected the following errors:
File clrjit.dll has failed the AppContainerCheck check.
Impact if not fixed: If the app doesn’t use the available Windows protections, it can increase the vulnerability of the customer's computer to malware.
How to fix: Apply the required linker options - SAFESEH, DYNAMICBASE, NXCOMPAT, and APPCONTAINER - when you link the app. See links below for more information:

This is when I build in release mode and run the certification program. App works fine when I deploy in debug and release on my pc. But when I run the certification on the release package of this app it fails. Also keep in mind that I did not add any nuget packages or other librarys. This is strikly only the the code from this github. Thanks.

When i use the API on Window Console. It work well
But when i use API on Window Form. The application is crash and can not close app in normal way.
This is Project i have done: https://drive.google.com/file/d/1G47jJayMH-I-xTOuZ01aZSsY1Or3RnDx/view?usp=sharing
Could you help me to fix that problem or update API?
So thank you if sending me the fixed project

I have been trying to login serveral times however I get nothing apart from a simple false boolean. Is there any way to debug why the login is failing? I have tried to use the example project as well but it also fails to login. I have checked email and password multiple times.
Regards

DoLogin() always returns false in UWP but it works in WinForms I'm using version 0.2.9

Any idea why this is happening?

Dont work any client commands like fetchProfile or fetchUser after authorization. It's just waiting a response all time without any results.

The included example works perfectly, but when I try to implement it in my project, an error is triggered "The header 'Referer' must be modified with the appropriate property or method".

The error is occurring at line 3363 of the Client.cs file

The exception is fired at the caller.

This error is really expected, as some Headers cannot be specified, as documented in HttpWebRequest.Headers.
But I did not find in MQTTnet.Client a way to specify the Referer directly in a property, in this way, I believe that the error is not in your code, but in MQTTnet.

The solution found was to add remark in 3 lines of code, as below and everything works fine.

I don't know why it works well with Net Core, because I didn't evaluate the MQTTnet code, but I believe it is a good idea to report the error to them and request a parse in the header properties and add the restricted headers in their corresponding properties.

Thank you very much and great work.

Facebook provides me a notification on attempt to login:
We noticed an unusual login from a device or location you don't usually use. Was this you?
I can select yes and also ask it to remember the browser but next login attempts also fail.
I have confirmed the username and password by typing it in manually again to login to facebook.
DoLogin returns false no matter the situation.

       // Instantiate FBClient
        FBClient client = new FBClient();
      
       // Login with username and password
       var logged_in = await client.DoLogin("username", "password");

Hi there and, firstly, thanks for the work done on this library!
I've had enough of Android and Facebook's bloated engineering so I started working on a lean UWP client for my Lumia 630 phone. Eventually I plan on porting all I need to return to WP10 and its lack of spam or bloat.

Your library exposes a On2FACode callback, which is great, unfortunately, I can't for the life of me figure out a way to ask for user input, wait for user input and read the user's input from a textbox within the same callback.

Now, the quickest, most miserable solution that came to me was polling - and, as expected, this broke the app (serves me right haha). I could set the client as a Singleton and spin the On2FACode callback in a parallel thread then put it to sleep and wake it again when the user finishes typing its 2FA code. I'll probably do just that.

Alternatively, if you could kindly consider exposing in the API something like a MessengerClient.Send2FACode(string input) method, that would be amazing!

Thanks for your time and keep on the awesome work!

When i use client.markAsRead(threadIds) i got exception "Error #1357031 when sending request: The content you requested cannot be displayed at the moment. It may be temporarily unavailable, the link you clicked on may have expired or you may not have permission to view this page."

I get this error = Unknown thread type: MARKETPLACE. I can see from your source code that there is no marketplace. Maybe Im doing something wrong? Im on Windows 10 UWP. Thanks.

I need to run multiple instances, receive and send messages on all of them at the same time.
I am able to easily send messages through the correct account, but when receiving messages, two things happen:

1. The "onMessage" event is triggered once for each account logged in, for example, if I have an account logged in, the event is triggered once. If I have 3 accounts, the same message triggers the event 3 times, each time with the same message.
2. I cannot identify the account that received the message. In all parameters of the event "onMessage", only the data of the sender is informed and at no time the recipient.

I tried in three ways and always with the same result:

• Instantiating a class multiple times:
  myClass runInctance1 = new myClass();
  myClass1.Login();
  myClass runInctance2 = new myClass();
  myClass2.Login();

• With Thread:
  Thread runInstance = new Thread (new ThreadStart (myClass.Login));
  runningInstance.Start ();

-With ThreadPool:
ThreadPool.QueueUserWorkItem (myClass.Login);

I believe I am doing something wrong, as I am not an expert in C# and your routine is very well done and working very well.
One more thing. I'm creating a .Net Standard 4.7 library (DLL) and haven't tested it with Core or any other way.

Thanks in advance.

Hi
I’m having trouble logging in to my messenger account that uses phone number instead of e-mail address as user. I only have messenger but no facebook account. If I use my dogs facebook account with e-mail it works great.

When I call Function FetchThreadMessages(thread_id:=chat_id, limit:=20) to get 20 Messages
It work very well

But if 20 Messages have Big Stikers or Like Stiker like this: https://drive.google.com/file/d/1ipHi9_AjuSvqzZPmaJUSb6kA5bOeJv_D/view?usp=sharing

And I get no Messages. Nothing Happen

Could you help me to fix that Problem?
Thank You So Much :D
