# json-rpc NV <= 1.2.7

*( node version <= v1.2.7 )*

JSON is a lightweight data exchange format. It can represent numbers, strings, ordered value sequences and key-value pairs.

JSON-RPC is a stateless, lightweight Remote Procedure Call (RPC) protocol. It defines several data structures and the relevant rules to handle them. JSON-RPC is transmission-agnostic, because it can be used in situations like process, socket, HTTP, or different message transmission environments. It uses JSON(RFC 4627) as the data format.

## Curl Examples Explained

The curl options below might return a response where the node complains about the content type, this is because the --data option sets the content type to application/x-www-form-urlencoded .

## JSON-RPC Support

#### Call

This method is used to execute a given transaction on a statedb of a given block height. It does not affect the statedb or blockchain and is useful for executing and retrieving values. However, the height currently does not support optional and will remove the from parameter in the next version or more.

| Type | Template                                                                 |
| ---- | ------------------------------------------------------------------------ |
| RPC  | `{"jsonrpc":"2.0","method":"seele_call ","params":[CallRequest],"id":1}` |

**Parameters**

* `to`:`string` - to address
* `payload`:`string` - transaction payload info
* `Height`:`int64` - block height (default: -1)

**Returns**

* `contract`:`string` - contract address
* `failed`:`bool` - contract executes successfully or not
* `poststate`:`string` - state trie root hash after transaction execution
* `result`:`string` - transaction result
* `totalFee`:`int64` - transaction fee
* `txhash`:`string` - transaction hash
* `usedGas`:`int64` - transaction gas

**Example**

When using the example below, the contract must be deployed first. The solidity code file:

```
pragma solidity ^0.4.0;

contract SimpleStorage {
    uint storedData=23;

    function set(uint x) {
        storedData=x;
    }

    function get() constant returns(uint) {
        return storedData;
    }
}
```

As you can see, the example is testing the get function.

* Request

  ```javascript
  curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"seele_call","params":["0x9df8ed11ea024183bd584480e80952c9b04e0122","0x6d4ce63c",-1],"id":1}' localhost:8037
  ```
* Result

  ```javascript
  {
    "jsonrpc": "2.0",
    "id": 1,
    "result": {
        "contract": "0x",
        "failed": false,

        "usedGas": 424
    }
  }
  ```

#### GetLogs

This method gets the event logs by block height, the contract address, and the event name.

| Type | Template                                                                       |
| ---- | ------------------------------------------------------------------------------ |
| RPC  | `{"jsonrpc":"2.0","method":"seele_getLogs ","params":[GetLogsRequest],"id":1}` |

**Parameters**

* `height`:`int64` - block height (default: -1)
* `contract`:`string` - contract address
* `abi`:`string` - contract abi
* `event`:`string` - event name

**Returns**

* `address`:`string` - contract address
* `topics`:`array` - topic array
* `data`:`string` - data
* `blocknumber`:`uint64` - block height
* `transactionNumber`:`uint` - the index of the transaction in the block

**Example**

When using the example below, the contract must be deployed first. The solidity code file:

```
pragma solidity ^0.4.0;

contract simple_storage_1 {
    uint storedData=23;

    event getLog(address addr, string message);
    event getLog1(string message);
    event getLog2(string message);

    function set(uint x) public{
        getLog1("set getLog1");
        getLog2("set getLog2");
        storedData=x;
    }

    function get() constant public returns(uint) {
        getLog(msg.sender, "get getLog");
        getLog1("get getLog1");
        set(16);
        return storedData;
    }
}
```

As you can see, this example is testing the get function. In this situation, the height is the block height of the block containing the get transaction.
