quarkchain-web3.js's Issues

Does contract.method.call() support all chainshards

myContractInstance.myMethod(param1 [, param2, ...] [, transactionObject] [, callback]) seems that doesn't support chainshards 1-7 contracts. Got undefined but on chainshard0 works right.

deploy contract with quarkchain-web3.js in browser without metamask

I forked qcgg/quarkchain-web3-contract-example.js and used it in browser. With MetaMask it woked fine. However, for supporting more browsers and more friendly to noob, I need use it without MetaMask. If I don't have a server, what should I do?

Here is my code.

I run the code in Safari and Chrome. All had the error as follows:

I would appreciate any suggestion!

Above all, when I used the sample code in server, I can only get the transactionId and no second callback for address but I can see the success of the deploy in testnet explorer, I need the contract address when I deploy it and tell the customers.

You can see I only get the txid back and then timeout. It's exactly same code besides I used require instead of import.

web3.qkc.getBalance() 和 sendTransaction() 两个函数无法调通

对应node节点版本：2.5.4
1、web3.qkc.getBalance()对应node节点中的eth_getBalance()，调用时node节点报错如下：

MASTER: File "/usr/local/lib/python3.6/dist-packages/jsonrpcserver/request.py", line 35, in handle_exceptions
MASTER: yield
MASTER: File "/usr/local/lib/python3.6/dist-packages/jsonrpcserver/async_request.py", line 21, in call
MASTER: result = await callable_(*(self.args or []), **(self.kwargs or {}))
MASTER: File "<decorator-gen-76>", line 2, in eth_getBalance
MASTER: File "/code/pyquarkchain/quarkchain/cluster/jsonrpc.py", line 351, in new_f
MASTER: res = await f(*args, **kwargs)
MASTER: File "/code/pyquarkchain/quarkchain/cluster/jsonrpc.py", line 1023, in eth_getBalance
MASTER: balance = account_branch_data.balance
MASTER: AttributeError: 'AccountBranchData' object has no attribute 'balance'

这个问题应该是node节点的问题。

我的调用代码如下：

web3.qkc.setPrivateKey('0x......')
var balance = web3.qkc.getBalance("0xB2ac5a...");
console.log(balance);

2、web3.qkc.sendTransaction()中缺少gasTokenId和transferTokenId两个变量。我观察到这两个变量是固定的，自行填充后再次调用sendTransaction()函数，仍有问题，node节点报错如下：

SLAVE_S1: W0403 15:24:22.294277 shard_state.py:516] Failed to add transaction: <Transaction(673a)>: 'nonce' actual:1 target:0

我观察到node节点侧通过签名(v,r,s)解析出来的EvmTransaction.sender和我私钥对应的地址不匹配，应该是这个原因导致的。但不确定是web3还是node节点的问题。是否可以给出一个例子呢？下面是我调用的代码：

web3.qkc.setPrivateKey('0x......')

var data = {
    to:'0xb2ac5ac...',
    value: '0x4563918244f40000',

Upgrade underlying web3js to latest

current web3 dependency is ^0.20.3 (i.e. <0.21), while the latest has been stable after 1.0.0 (latest 1.2.1)

the latest version also has better support for pub/sub using subscribe endpoint instead of newFilter which is not supported yet in our JSONRPC

Create smart contract with quarkchain web3

I have built an app which aims to create an ICO smart contract with data included from form inputs. You can see the app here: https://jsfiddle.net/m81470rb/

We have not yet set up a server, but would like to test the frontend code. How should I implement it? I have looked at other examples, but cannot understand how the abi is sent off (and in fact what it does). If you could point me in a direction of what needs to be done for this contract to be created, I would be grateful. There is a js object which stores all of the form data, and which can be possibly accessed by web3.

guide to quarkchain-web3.js for the web

Hi,

I want to use the quarkchain-web3.js to create contracts for ICO projects through a web app. However, I run into a problem when installing it for use in a web app (clientside browser). Once the js is installed, how do I use it with a web app to send user inputs. That is how do I put it all together to be sent to cluster?

Thanks,
K

Is QuarkChain.getQkcAddressFromEthAddress method not long avaliable?

When I using this method in my js script, it print this error.

152 Uncaught (in promise) TypeError: QuarkChain.getQkcAddressFromEthAddress is not a function.

Add getBalances

Now, web3.qkc.getBalance only returns balance of QKC. Will we add getBalances to support native tokens as JRPC does?

web3.qkc.getTransactionReceipt.contractAddress is a qkc address

It's different in readme.

contractAddress : String - 20 Bytes - The contract address created without full shard id, if the transaction was a contract creation, otherwise null. To build a QKC contract address, append the toFullShardId used in the contract creation transaction. Normally you should use web3.qkc.contract(abi).new() which returns the QKC address in the callback.

Can't interact with Contract in browser

I deployed an ICO smart contract with abi that include:

{
    "constant": true,
    "inputs": [],
    "name": "totalSupply",
    "outputs": [
      {
        "name": "",
        "type": "uint256"
      }
    ],

In my HMTL file, I have the following javascript, I would expect this to return the totalSupply, but instead, I get "undefined".

ethAddr=QuarkChain.getEthAddressFromQkcAddress("0x13970840784104FC13664095aAb517f773dD47cd134140f7");
var MyContract = web3.qkc.contract(abi);
var myContractInstance = MyContract.at(contractAddr);
result = await myContractInstance.totalSupply();

Any ideas?

Add getTokenIdFromName

Shall we add a function like QuarkChain.getTokenIdFromName to make it easier when developing native token app?

gas or gasLimit in rawTx

The gas(gasLimit) param in rawTx is different when you use web3 or jrpc. It's 'gas' in quarkchain-web3 and 'gasLimit' in jrpc. Is it better that they are the same?
