框架及祕鑰支持

框架	祕鑰
fabric	SM2，secp256r1

-fabric框架應用使用secp256r一、SM2 祕鑰的祕鑰託管和祕鑰上傳兩種模式javascript

1. 調用前準備

應用參數java

應用參數是用戶在建立應用成功以後在應用詳情頁面獲取，或者由本地設置的一些參數，具體包含如下參數git

網關接口地址：網關接口的調用地址

//網關接口地址ip
    private static String BASE_URL = "http://ip:port";

用戶名稱：帳本的用戶名稱

headers.put("username", "admin")

用戶密碼：用戶的密碼

headers.put("password", "password");

應用編號：參與的應用的編號

headers.put("app_id", "scm_qa");

帳本編號：參與的帳本的編號

headers.put("accountbook_id", "zj_scm_qa");

合約編號：參與的合約的編號

headers.put("contract_id", "survey");

2. 準備調用

//網關接口地址
    private static String BASE_URL = "http://localhost:8023";
    //URI爲固定值，不用修改
    private static String TRANSACTION_URI = "/transaction";
    private static String QUERY_URI = "/query";

    public static void main(String[] args) {
        //建立交易
        insert();
        //修改
        updte();
        //取消
        cancel();
        //刪除
        delete();
        //查詢指定交易
        query();
        //查詢指定交易變動歷史
        getHistory();
        //查詢交易列表
        list();
    }
