I am writing a web API to get data from a multi-index table by passing its key which is the primary key?
Is there any method available?

I wrote web API to get all records of table using:

var result = await eos.GetTableRows(new GetTableRowsRequest() {
    json = true,
    code = "eosio.token",
    scope = "EOS",
    table = "stat"
});

By default, it gives first 10 records only. I know, if I want more I can give limit option parameter. But what if I need all records from a table? What value should I set the limit value to get all records of the table? Please guide.

EOS contract code

struct  airquality_struct
    {
        uint64_t        air_id;
        std::string     air_place;
        std::string     air_pm2_5;
        std::string     air_voc;
        std::string     air_carbon;
        std::string     air_nitrogen;
        std::string     air_sulfur;
        std::string     air_longitude;
        std::string     air_latitude;
    };
    typedef std::vector<airquality_struct> airquality_list;

To Reproduce

1. Setup a contract with a single action, where one of the parameters is signature type.
   ACTION test(signature sig);
2. Write code using scatter-sharp (or eos-sharp) that creates and pushes a transaction that contains the above action.
3. The CreateTransaction function should fail with the above exception regardless of the value of the sig parameter.

Analysis

The exception is being thrown in CryptoHelper.cs#L178. I took the code from CryptoHelper and created a small script that runs the same code and generated the below output. I appears that not only do the checksums not match, but they aren't even the same length.

It appears that packing of the transaction is dropping the last byte of the signature?

I use the following method for signing a hash of data (the resulting sig seems to be valid):

        public static string SignHash(byte[] hash, string privateKey) {
            var sign = Secp256K1Manager.SignCompressedCompact(hash, EosSharp.Core.Helpers.CryptoHelper.GetPrivateKeyBytesWithoutCheckSum(privateKey));
            var check = new List<byte[]>() { sign, Encoding.UTF8.GetBytes("K1") };
            var checksum = Ripemd160Manager.GetHash(EosSharp.Core.Helpers.SerializationHelper.Combine(check)).Take(4).ToArray();
            return "SIG_K1_" + Base58.Encode(EosSharp.Core.Helpers.SerializationHelper.Combine(new List<byte[]>() { sign, checksum }));
        }

SerializationHelper.DecimalToBinary does not convert correctly to byte array

uint64 10001 converted to 17 
uint64 10002 converted to 18 

How to get the total count of Actions. I am doing this,

var r = getEos();
var resultaction = await r.GetActions("groupaccount", 0, 1000);

Instead of 1000, I want to give the maximum count. I need to display all actions. Please help

Hey there guys,
Wanted to bring to attention that eos-sharp is not actively maintained anymore.

I'm open to discussing possible viable solutions to continue this if it is in the interest of the EOSIO community

Regards

If the value of a "dictionary type Transaction Data" contain a comma, It will response "Input string is not in a correct format" error when sending transaction.

For example:

Data = new Dictionary<string, string>()
 {
    { "owner", "tester112345" },
    { "sym", "4,HVT" }
 }

If the value of "sym" is "4,HVT", the transaction can't be send out, but "4.HVT" can.

When casting an object to a float, using parenthesis casting causes an InvalidCastException. I only just started reading a few of the articles linked below to catch myself up with this issue and learn more about how casting works in C#, but our testing shows that changing the code to use the conversion tool handles this just fine.

 private static void WriteFloat32(MemoryStream ms, object value)
 {
    // ms.Write(BitConverter.GetBytes((float)value), 0, 4);
    ms.Write(BitConverter.GetBytes(Convert.ToSingle(value), 0, 4);
 }

Currently we're running in Unity and just pulled down this repository straight into our project out of simplicity so we are able to use this work around now. If there's anything we're missing please let us know and we appreciate your help!

Currently, eos sharp is failing on iOS due to the following error:

System.Reflection.Emit is not supported.

This is called by FastMember.TypeAccessor.Create

Unfortunately, for iOS support we need to replace all functions using System.Reflection.Emit.

Has anybody generated unique id like UUID in eos smart contract? I need to generate, trying boost library but not sure. Please help.

Need to add some basic examples for highly used methods like

• GetInfo
• GetBlock
• GetTableRows

I am writing web API to get users data from multi-index table data. Below is my API method:

[HttpGet]
        public async IAsyncEnumerable<GetTableRowsResponse>  GetUsers()
            //public async Task<IHttpActionResult> GetUsers()
        {
            Eos eos = new Eos(new EosConfigurator()
            {
                HttpEndpoint = "http://127.0.0.1:8888/v1/chain", //running nodeos on localhost
                ChainId = "nodeoschainid",
                ExpireSeconds = 60,
                SignProvider = new DefaultSignProvider("MyPK")
            });

            var result = await eos.GetTableRows(new GetTableRowsRequest()
            {
                json = true,
                code = "groupacc",
                scope = "groupacc",
                table = "users"
            });

            yield return result;
        }

This is throwing exception:

ApiErrorException: Exception of type 'EosSharp.Core.Exceptions.ApiErrorException' was thrown.

I have users data in multi-index table users and return all users from API. can anybody help me with the error and return types?

Hi, I generate a keypair using

eosKeyPair = EosSharp.Core.Helpers.CryptoHelper.GenerateKeyPair();

and then create a new EOS account with the public key. This works fine.

But when I try to sign a transaction in eos-sharp I get a check-sum-error-exception.
When I try to import the private key to Scatter I get "Private key not long enough".

This is an example of a private key generated that don't work:
2jTY92qynZetndq69sPif3Yp4hyBd3wduwaar7BafNUKx7K5vp

What am I doing wrong?

Steps to reproduce:

var keyPair = EosSharp.Core.Helpers.CryptoHelper.GenerateKeyPair();
var pubKeyBytes = [EosSharp.Core.Helpers.CryptoHelper.PubKeyStringToBytes(keyPair.PublicKey);
var encrypted = EosSharp.Core.Helpers.CryptoHelper.AesEncrypt(pubKeyBytes, "Testing testing"); // The error throws here

Hell, I could be doing this wrong but I couldn't find any documentation on these functions.

I tried to send a "newaccount" transaction, but got "Out of Range" message from EOS node.

Hey - Nuget packages is out of date. Would you mind update it ?

thanks

var result = await eos.CreateTransaction(new EosSharp.Api.v1.Transaction() { Actions = new List<EosSharp.Api.v1.Action>() { new EosSharp.Api.v1.Action() { Account = "eosio", Authorization = new List<PermissionLevel>() { new PermissionLevel() {Actor = "myeosaccount", Permission = "owner" } }, Name = "voteproducer", Data =new { voter = "myeosaccount", proxy = "", producers =new string[] { "eosbeijingbp", "eoscannonchn" } } } } });

The above code can run, but if the producers order is changed, it won't run:

var result = await eos.CreateTransaction(new EosSharp.Api.v1.Transaction() { Actions = new List<EosSharp.Api.v1.Action>() { new EosSharp.Api.v1.Action() { Account = "eosio", Authorization = new List<PermissionLevel>() { new PermissionLevel() {Actor = "myeosaccount", Permission = "owner" } }, Name = "voteproducer", Data =new { voter = "myeosaccount", proxy = "", producers =new string[] { "eoscannonchn", "eosbeijingbp"} } } } });

The EOS mainnet will response "voteproducer eosio_assert_message assertion failure" for this code.

Tested this using cleos and eosjs and this works as expected.

I use a 50 thread loop queue to perform "get_block" , total of 100,000 blocks, and finally there will always be 1-3 threads in the "runing" state can not exit.

I found that the code for these threads is running to line 115 of the HttpHelper.cs:
return JsonSerializer.Create(jsonSettings).Deserialize(jtr);

Class CryptoHelper contains an incorrect constant 'SIGN_KEY_DATA_SIZE', expected 65, current 64

EOS 1.5.0 made a number of changes to Get Table: https://github.com/EOSIO/eos/releases/tag/v1.5.0
We need to add support for reverse search and showing ram payer.

I installed eos-sharp in the visual studio using the NuGet package. My code is as below:

using EosSharp;
using EosSharp.Core;
using EosSharp.Core.Providers;
using System.Windows.Forms;

namespace eostest
{
    public partial class Form1 : Form
    {
        Eos eos = new Eos(new EosConfigurator()
        {
            HttpEndpoint = "https://127.0.0.1:8888",
            ChainId = "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
            ExpireSeconds = 60,
            SignProvider = new DefaultSignProvider("myprivatekey")
        });

        public Form1()
        {
            InitializeComponent();
            getinfo();
        }

        public async void getinfo()
        {
            var result = await eos.GetInfo();
        }
    }
}

Nodeos is running on the localhost. I confirmed by using http://localhost:8888/v1/chain/get_info which shows the output. When I run this program, nothing happens.
After 1:40 minutes it throws an exception as below:

This exception was originally thrown at this call stack:

How would I confirm whether the parameters are correct and the chain is connected or not? Any help would be appreciated.

Using cleos I am using command to call action and it works:

cleos push action groupsample erase '["user2"]' -p groupsample@active

groupsample is the account used for deploying a smart contract and authorization also.

I want to do this in .Net using eos-sharp. I am trying this:

public async Task pushaction()
        {
            try
            {
                var result = await eos.CreateTransaction(new EosSharp.Core.Api.v1.Transaction()
                {
                    actions = new List<EosSharp.Core.Api.v1.Action>()
    {
                    new EosSharp.Core.Api.v1.Action()
                    {
                        account = "groupsample",
                        authorization = new List<PermissionLevel>()
                        {
                            new PermissionLevel() {actor = "groupsample", permission = "active" }
                        },
                        name = "erase",
                        data = new Dictionary<string, string>()
                        {
                            { "key", "user2" }  
                        }
                    }
    }
                });
            }
            catch(Exception ex)
            {
                
            }
        }

But this is throwing an exception:

Exception of type 'EosSharp.Core.Exceptions.ApiErrorException' was thrown.

Following the main readme.md the Memo doesn't seem to be printing. You can check under the account 'mirrorserver' on the main net.

Hi guys,

I am using eos-sharp with Xamarin to build a wallet app for eos.io bloackchain

The problem is when I tried to connect to Blockchain node which support only TLS1.2

HttpClient couldn't connect to node and thrown SSL exception:

The SSL connection could not be established.

After doing some research I found that the solution is to add

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

before connection to Blockchain node API. But unfortunately it doesn't affect HttpClient on .Net Core

Finally I found this Solution on Stackoverflow

https://stackoverflow.com/questions/49399205/how-to-use-tls-1-2-in-asp-net-core-2-0

And the solution is to use HttpHandler with HttpClient :

var handler = new HttpClientHandler
{
SslProtocols = SslProtocols.Tls12 | SslProtocols.Tls11 | SslProtocols.Tls
};

HttpClient client = new HttpClient(handler);

My question is can I addHttoClient Handler which supports TLS12 to EosSharpHttpHandler

And make it optionally to force support tls12?

Thanks

Hi, are you planning to distribute it throught nuget ?

Hi,

I couldn't find much information on how to generate the associated public key if you have a private key with you in eos-sharp. I could only see public/private key pairs being generated only when we make use of generateKeyPair. Is there a functionality to generate public key if you have only the private key with you in eos-sharp?

JsonReaderException: Could not convert string to integer: 499999950150. Path 'net_weight', line 1, position 271.

Will probably also fail on cpu_weight. Should be something larger than Int32.

I found in use that sending memo information in Korean is always truncated.

For example: "hihihi만들어드립니다만들어드립니다다만들어드립니다hihihi"
Show when viewing the transaction:
(Memo: hihihi만들어드립니다만들�)

The line 146 of EosSharp/Helpers/CryptoHelper.cs should be:

keyType == "sha256x2" ? SerializationHelper.Combine(new List<byte[]>() { new byte[] { 128 }, key }) : key,

or it will not return the correct string while keyType == "sha256x2".

Your package only contains .net standard 2.0
How about adding .NetFramework binaries?

If transfer 0.1 EOS using EOS.CreateTransaction method, It will transfer 0.0232 EOS. the EOS amount is changed.

I can't find a function to generate an eos private key in eos-sharp.

The type of EosSharp.Api.v1.BlockTransaction.Trx is BlockDetailedTransaction, but many times you only get a hash string on "trx" from EOS blockchains while run "Api.GetBlock", and if got a string, the CreateTransaction method will not run.

Hi, i am triyng to make push a transaction with Xamarin app.

Here is my code:

static async Task sendTransaction(int id, string datatx)
{
Console.WriteLine("Empieza SEND Tx");
string idTX = id.ToString();
Console.WriteLine("Tx to id: " + idTX);

        GlobalVariables.idPUT = GlobalVariables.initialLastID + 1;


        try {
            var result2 = await eos.CreateTransaction(new Transaction()
            {
                actions = new List<EosSharp.Core.Api.v1.Action>()
           {
            new EosSharp.Core.Api.v1.Action()
            {
                account = "crud",
                authorization = new List<PermissionLevel>()
                {
                    new PermissionLevel() {actor = "bob", permission = "active" }
                },
                name = "create",
                data = new { user = "bob", id = idTX, data = datatx }
                }
            }
            });
            Console.WriteLine("Tx realizada");
        }
        catch (Exception ex) { Console.WriteLine(ex); }

    }

It is returning the following error:
