+# eosio-ipfs
+EOSIO + IPFS 私鏈快速生成器
+
+## 資料夾結構
+
+## 必須套件
+本系統透過Docker與Docker-Compose生成環境，請先設置好EOSIO + IPFS
+
+## EOSIO 私鏈架設流程
+1. 進入容器
+```
+docker exec -it nodeos bash
+```
+
+2. 新增錢包
+```
+cleos wallet create --file ~/wallet.passwd
+```
+
+3. 開啟錢包
+```
+cleos wallet open
+```
+
+4. 查看目前己開啟錢包
+```
+cleos wallet list
+```
+
+5. 解鎖錢包，密碼在~/wallet.passwd檔案中
+```
+cleos wallet unlock
+```
+
+6. 匯入設定檔中私鑰，私鑰在/mnt/dev/config/config.ini中，裡面的signature-provider，例如我這邊私鑰是5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
+```
+cleos wallet import --private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
+```
+
+7. 新增二把含以上的公鑰，等等新增會員時要用到
+```
+cleos wallet create_key
+```
+
+8. 查看可用的公私鑰
+```
+cleos wallet private_keys
+```
+
+9. 新增會員帳號
+```
+cleos create account eosio [會員帳號] [會員公鑰]
+```
+
+10. 查看會員可用資源
+```
+cleos get account [會員帳號]
+```
+
+## 撰寫 Hello World 智能合約
+1. Hello World
+```
+#include <eosio/eosio.hpp>
+
+using namespace eosio;
+
+class [[eosio::contract]] helloworld : public contract {
+    public:
+        using contract::contract;
+
+    [[eosio::action]]
+    void hi(name user) {
+        print("Hi! ", user, " Hello World!!!");
+    }
+};
+```
+
+2. 編譯智能合約
+```
+eosio-cpp -abigen -o [智能合約所在資料夾]/helloworld.wasm [智能合約所在資料夾]/helloworld.cpp
+```
+
+3. 查看可用公鑰
+```
+cleos wallet keys
+```
+
+4. 新增帳號發布智能合約，EOS當中，一個帳號只能發佈一份智能合約
+```
+cleos create account eosio [會員帳號] [會員公鑰] -p eosio@active
+```
+
+5. 發佈智能合約
+```
+cleos set contract [智能合約名稱] [智能合約在屬資料夾] -p [會員帳號]@active
+```
+
+6. 調用智能合約，調用智能合約與上合約的不能同一人
+```
+cleos push action [智能合約名稱] [調用的 Action] '[[代入參數]]' -p [會員帳號]@active
+```
+
+## 撰寫資料長期儲存智能合約
+1. 上傳打卡鐘資料
+```
+#include <eosio/eosio.hpp>
+
+using namespace eosio;
+
+class [[eosio::contract("punchclock")]] punchclock : public eosio::contract {
+	public:
+		punchclock(name receiver, name code,  datastream<const char*> ds): contract(receiver, code, ds) {}
+
+		[[eosio::action]] //新增資料
+		void add(std::string punchTime, std::string doorNo, std::string cardNo, std::string identify, name user) {
+			require_auth(user);
+			punchListIndex lists(get_self(), get_first_receiver().value);
+			lists.emplace(user, [&](auto& row) {
+				row.id = lists.available_primary_key();
+				row.creater = user.value;
+				row.punchtime = punchTime;
+				row.doorno = doorNo;
+				row.cardno = cardNo;
+				row.identify = identify;
+			});
+		}
+
+		[[eosio::action]] //刪除資料
+		void remove(uint64_t id, name user) {
+			require_auth(user);
+			punchListIndex lists(get_self(), get_first_receiver().value);
+			auto iterator = lists.find(id);
+			check(iterator != lists.end(), "Record does not exist");
+			lists.erase(iterator);
+		}
+		
+		[[eosio::action]]
+		void get(std::string identify, name user) {
+		    require_auth(user);
+		    punchListIndex lists(get_self(), get_first_receiver().value);
+		    auto iterator = lists.begin();
+		    while(iterator != lists.end()) {
+		        if (identify == iterator->identify) {
+		            print(iterator->identify);
+		        }
+		    }
+		}
+
+	private:
+		struct [[eosio::table]] punchList { //punchList資料表
+			uint64_t id;
+			uint64_t creater;
+			std::string punchtime;
+			std::string doorno;
+			std::string cardno;
+			std::string identify;
+			uint64_t primary_key() const { return id; }
+			uint64_t get_secondary_1() const { return creater; }
+		};
+		typedef eosio::multi_index<"punchclock"_n, punchList,
+		    indexed_by<"bycreater"_n, const_mem_fun<punchList, uint64_t, &punchList::get_secondary_1>>
+		> punchListIndex;
+};
+```
+
+2. 調用智能合約
+```
+cleos push action punchclock add '["2019-06-08 11:28:00", "A01", "ABCDEFG", "00001", "bob"]' -p bob@active
+```
+
+3. 查看線上資料庫
+```
+root@a9e45804cee8:~/contracts# cleos get table [會員帳號] [上鏈的會員帳號] [資料表名]
+```
