以太坊 eth_sendTransaction 通过 PHP curl

Question

我正在尝试使用 PHP curl

发送以太坊交易

还有许多其他呼叫成功，但这个...

代码片段：

$url = "http://127.0.0.1:9999";

        $data = array(
                "jsonrpc" => "2.0",
                "method" => "eth_sendTransaction",
                "params" => array("from" => $f, "to" => $t, "gas" => $gv, "gasPrice" => $gp, "value" => $value),
                "id" => "1"
        );

        $json_encoded_data = json_encode($data);

        var_dump($json_encoded_data);

        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POSTFIELDS, $json_encoded_data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                'Content-Type: application/json',
                'Content-Length: ' . strlen($json_encoded_data))
        );

        $result = json_decode(curl_exec($ch));
        curl_close($ch);

        $parsed = $result->result;

        return $parsed;

JSON 编码数据：

{"jsonrpc":"2.0","method":"eth_sendTransaction","params":{"from":"0x35fa3c7edd23b23bd714fd075d243097e14ed937", "to":"0xdab9a603ed3f1cf7b2b89f1cb1b57145e4828796","gas":"0x15f90","gasPrice":"0x430e23400","value":"0x9b6e64a8ec60000"},"id":"1"}

交易未提交，除了日志 Notice 之外没有错误 PHP Notice: Undefined property: stdClass::$result in...

命令行：

curl -H "Content-type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_sendTransaction","params":[{"from":"0x35fa3c7edd23b23bd714fd075d243097e14ed937","to":"0xdab9a603ed3f1cf7b2b89f1cb1b57145e4828796","gas":"0x15f90","gasPrice":"0x430e23400","value":"0x9b6e64a8ec60000"}],"id":"1"}' http://localhost:9999

以上完美运行...

有人能指出我做错了什么吗？
