為了使本技術領域的人員更好地理解本說明書一個或多個中的技術方案，下面將結合本說明書一個或多個實施例中的附圖，對本說明書一個或多個實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅僅是本說明書一個或多個一部分實施例，而不是全部的實施例。基於本說明書一個或多個中的實施例，本領域普通技術人員在沒有作出創造性勞動前提下所獲得的所有其他實施例，都應當屬本說明書一個或多個保護的範圍。
本說明書一個或多個實施例提供了一種掃碼控制方法、裝置及系統，由於設備終端上顯示的圖形碼是動態變化的，以使客戶端上傳的動態密碼應具有一定時效性，這樣能夠借助動態密碼的時效性識別客戶端是否被攻擊，針對識別出客戶端被惡意用戶非法攻擊的情況，及時進行有效控制，避免給正常用戶帶來不必要的損失。
圖1為本說明書一個或多個實施例提供的掃碼控制系統的應用場景示意圖，如圖1所示，該控制系統包括：後台服務端、客戶端和設備終端，其中，該客戶端可以是智慧型手機、平板電腦等行動終端，該後台服務端可以是用於對設備終端進行管理控制且具有saas服務的後台伺服器，該設備終端可以是掃碼售賣設備、掃碼租賃產品等等，其中，掃碼控制的具體過程為：
首先，客戶端向後台服務端發送設備控制請求，其中，該設備控制請求中攜帶有目標動態密碼；
具體的，客戶端可以是基於主動對設備終端上的圖形碼進行掃碼操作而發出的設備控制請求，即屬正常主動請求控制設備終端；客戶端還可以是在惡意用戶透過非法手段觸發下而發出的設備控制請求，即被攻擊後被動請求控制設備終端；
然後，後台服務端接收到上述設備控制請求後，判斷該設備控制請求中攜帶的目標動態密碼是否滿足預設時效性條件；
具體的，針對客戶端基於對設備終端上的圖形碼進行掃碼操作而發出的設備控制請求的情況，設備控制請求中攜帶的目標動態密碼是有效的；由於設備終端上顯示的圖形碼對應的動態密碼是動態更新的，惡意用戶從獲取動態密碼再到觸發正常用戶向後台服務端發出攜帶該動態密碼的設備控制請求的過程需要一定時間，因此，針對客戶端在惡意用戶透過非法手段觸發下而發出的設備控制請求的情況，設備控制請求中攜帶的目標動態密碼是無效的；
最後，後台服務端根據針對目標動態密碼的時效性判斷結果執行相應的控制操作；
具體的，當確定出目標動態密碼有效時，說明客戶端屬正常主動向後台服務端請求控制設備終端，此時，後台服務端需要正常響應該設備控制請求，控制設備終端執行相應的控制動作；當確定出目標動態密碼無效時，說明客戶端屬被攻擊而向後台服務端請求控制設備終端，此時，後台服務端需要向客戶端回傳提示資訊，從而實現對惡意用戶的非法攻擊行為進行有效控制，避免給正常用戶帶來不必要的損失。
圖2為本說明書一個或多個實施例提供的掃碼控制方法的第一種流程示意圖，圖2中的方法能夠由圖1中的後台服務端執行，如圖2所示，該方法至少包括以下步驟：
S201，接收客戶端發送的設備控制請求，其中，該設備控制請求中攜帶有目標動態密碼；
具體的，後台服務端接收到的設備控制請求可以是客戶端基於主動對設備終端上的圖形碼進行掃碼操作而發出的，即屬客戶端正常主動請求控制設備終端；還可以是客戶端在惡意用戶透過非法手段觸發下而發出的，即屬客戶端被攻擊後被動請求控制設備終端；
S202，判斷設備控制請求中攜帶的目標動態密碼是否滿足預設時效性條件，其中，該目標動態密碼與目標設備終端上顯示的動態更新的圖形碼一一對應，即在掃描圖形碼驗證階段，確定目標動態密碼的時效性，以識別是否存在用戶被攻擊的情形，針對設備終端為掃碼售賣設備的情況，該掃描圖形碼驗證階段即為用戶使用客戶端掃描圖形碼請求打開開門頁面的過程；
具體的，針對客戶端基於對設備終端上的圖形碼進行掃碼操作而發出的設備控制請求的情況，設備控制請求中攜帶的目標動態密碼是滿足預設時效性條件的，即目標動態密碼對應的圖形碼未失效，此時設備終端上顯示的圖形碼對應的動態密碼即為該目標動態密碼；
針對客戶端在惡意用戶透過非法手段觸發下而發出的設備控制請求的情況，設備控制請求中攜帶的目標動態密碼是不滿足預設時效性條件的，即目標動態密碼對應的圖形碼已失效，此時設備終端上顯示的圖形碼對應的動態密碼不是該目標動態密碼；
S203，根據針對目標動態密碼的時效性判斷結果執行相應的控制操作，其中，該判斷結果可以是目標動態密碼滿足預設時效性條件，還可以是目標動態密碼不滿足預設時效性條件；
具體的，若目標動態密碼滿足預設時效性條件，說明客戶端屬正常主動向後台服務端請求控制設備終端，此時，後台服務端需要正常響應該設備控制請求，控制設備終端執行相應的控制動作；若目標動態密碼不滿足預設時效性條件，說明客戶端屬被攻擊而向後台服務端請求控制設備終端，此時，後台服務端需要向客戶端回傳提示資訊，例如，觸發客戶端展示報錯頁面。
本說明書一個或多個實施例中，透過後台服務端控制設備終端上顯示的圖形碼動態更新，由於設備終端上顯示的圖形碼是動態變化的，以使客戶端上傳的動態密碼應具有一定時效性，這樣能夠借助動態密碼的時效性識別客戶端是否被攻擊，針對識別出客戶端被惡意用戶非法攻擊的情況，及時進行有效控制，避免給正常用戶帶來不必要的損失。
其中，如圖3所示，上述S203根據針對目標動態密碼的時效性判斷結果執行相應的控制操作，具體包括：
若判斷結果為是，則執行S2031，向客戶端回傳業務頁面，以使該客戶端基於該業務頁面向後台服務端請求控制目標設備終端；
具體的，針對判斷結果為是的情況，即目標動態密碼滿足預設時效性條件，說明客戶端屬正常主動向後台服務端請求控制設備終端，此時，後台服務端需要正常響應該設備控制請求，即後台服務端可以直接向設備終端發送控制指令，例如，下發開門指令；為了進一步提高設備控制的準確度，還可以先向客戶端回傳用於渲染業務頁面的業務資料，以使用戶基於客戶端展示的業務頁面向客戶端發送確認控制資訊，對應的，後台服務端接收到該確認控制資訊後，控制設備終端執行相應的控制動作；
若判斷結果為否，則執行S2032，向客戶端回傳第一提示資訊，以使該客戶端基於該第一提示資訊進行提示；
具體的，針對判斷結果為否的情況，即目標動態密碼不滿足預設時效性條件，說明客戶端屬被攻擊而向後台服務端請求控制設備終端，此時，後台服務端需要向客戶端回傳第一提示資訊，以提示用戶當前存在被攻擊的可能性，另外，還可以在客戶端顯示的第一提示資訊的展示頁面上，提供確認提交設備控制請求的選項，例如，提供手動提交開門請求的選項，以防止因客戶端掃碼延時而出現上傳的目標動態密碼失效的情況下導致無法交易的問題。
進一步的，為了進一步提高設備控制的準確度，還可以先向客戶端回傳用於渲染業務頁面的業務資料，以使用戶基於客戶端展示的業務頁面向客戶端發送確認控制資訊，基於此，如圖4所示，在上述S2031向客戶端回傳業務頁面之後，還包括：
S2033，接收客戶端針對展示的業務頁面發送的控制確認資訊，其中，針對設備終端為掃碼售賣設備的情況，該業務頁面可以是開門確認頁面，當客戶端檢測到用戶在開門確認頁面上點擊開門選項後，向後台服務端發送確認開門資訊，針對設備終端為掃碼租賃產品的情況，該業務頁面還可以是開鎖確認頁面，當客戶端檢測到用戶在開鎖確認頁面上點擊開鎖選項後，向後台服務端發送確認開鎖資訊；
S2034，基於接收到的控制確認資訊向目標設備終端發送控制指令，以使該目標設備終端執行相應的控制動作，其中，該控制指令可以是開門指令，還可以是開鎖指令，對應的，該目標設備終端執行的控制動作可以是開門操作，還可以是開鎖操作等等。
其中，後台服務端需要按照預設規則生成包含動態密碼的圖形碼資訊，並將該圖形碼資訊下發給對應的設備終端，以使設備終端顯示於該圖形碼資訊對應的圖形碼，這樣能夠保證設備終端上顯示的用於提供客戶端掃描的圖形碼是動態更新的，從而保證客戶端上傳的設備控制請求中攜帶的目標動態密碼是動態變化的，以便後續基於對目標動態密碼的時效性判斷來確定執行何種控制操作，具體的，如圖5所示，在上述S201接收客戶端發送的設備控制請求之前，還包括：
S204，根據目標設備終端的設備標識、與該設備標識對應的標識密鑰以及時間戳資訊中的至少兩個，確定動態密碼，其中，該設備標識可以是預先為每個設備終端分配的唯一性標識，該標識密鑰可以是按照預設方式基於設備標識確定的，該時間戳資訊可以是確定動態密碼時的當前時間戳，具體的，可以將該動態密碼儲存於key-value資料庫（即redis）中；
S205，根據確定出的動態密碼，生成圖形碼資訊，其中，該圖形碼資訊可以是預設URL地址與動態密碼拼接得到的，即可以將動態密碼添加至URL地址的尾端，例如，該URL地址可以是https://alipay.com/detail.htm；
S206，將生成的圖形碼資訊下發給目標設備終端，以使該目標設備終端基於該圖形碼資訊顯示相應的圖形碼，其中，由於每次生成的動態密碼各不相同，因此，圖形碼資訊各不相同，以使設備終端展示的圖形碼是動態更新的，該圖形碼可以是二維碼，還可以是條形碼；
具體的，為了降低設備終端的製造成本，可以以電子墨水標簽屏幕作為圖形碼顯示螢幕，例如，設備終端上設置的用於顯示圖形碼的顯示螢幕可複用。
其中，客戶端在掃描目標設備終端上顯示的圖形碼時，能夠解析出該圖形碼對應的目標動態密碼，再基於該目標動態密碼生成設備控制請求，以及向後台服務端發送該設備控制請求，以使該後台服務端基於該設備控制請求對目標設備終端進行控制。
進一步的，為了提高目標動態密碼的時效性的判斷效率和判斷準確度，可以將失效的動態密碼自動刪除，進而在接收到設備控制請求後，判斷是否存在該設備控制請求中攜帶的目標動態密碼，從而確定該目標動態密碼是否滿足預設時效性條件，基於此，如圖6所示，在上述S206將生成的圖形碼資訊下發給目標設備終端之後，還包括：
S207，將確定出的動態密碼添加至動態密碼集合中，以及當任一動態密碼滿足預設銷毀條件時，將該動態密碼從動態密碼集合中移除，其中，該預設銷毀條件包括：動態密碼達到預設存活時間及/或動態密碼已使用，具體的，動態密碼達到預設存活時間是指動態密碼的存貨時間大於預設時效閾值，即動態密碼過期銷毀，動態密碼已使用是指已針對該動態密碼進行設備終端控制，即動態密碼已使用銷毀，其中，該動態密碼集合包括至少一個有效的動態密碼，該動態密碼集合設置於key-value資料庫（即redis）中；
對應的，上述S202判斷設備控制請求中攜帶的目標動態密碼是否滿足預設時效性條件，具體包括：
S2021，判斷動態密碼集合中是否存在設備控制請求中攜帶的目標動態密碼；
若判斷結果為是，則確定目標動態密碼滿足預設時效性條件，並執行上述S2031向客戶端回傳業務頁面，以使該客戶端基於該業務頁面向後台服務端請求控制目標設備終端；
若判斷結果為否，則確定目標動態密碼不滿足預設時效性條件，並執行上述S2032向客戶端回傳第一提示資訊，以使該客戶端基於該第一提示資訊進行提示。
具體的，當將某一動態密碼從動態密碼集合中移除後，說明該動態密碼對應的圖形碼變為失效，需要更新對應的設備終端上顯示的圖像碼，基於此，上述S207將該動態密碼從動態密碼集合中移除之後，還包括：
生成新的動態密碼，基於該新的動態密碼更新對應的目標設備終端上顯示的圖形碼；
具體的，生成新的動態密碼的過程，參見上述步驟S204，其中，生成新的動態密碼後，根據該動態密碼，生成圖形碼資訊，將該圖形碼資訊下發給對應的目標設備終端，以更新該目標設備終端上顯示的圖形碼。
其中，上述S204根據目標設備終端的設備標識、與該設備標識對應的標識密鑰以及時間戳資訊中的至少兩個，確定動態密碼，具體包括：
利用消息摘要算法根據目標設備終端的設備標識、與該設備標識對應的標識密鑰以及時間戳資訊的至少兩個，確定動態密碼，其中，該消息摘要算法可以是md5加密算法，具體的，利用md5加密算法對設備id、與該設備id對應的唯一key以及時間戳資訊中至少兩個進行md5加密，生成sign字段。
其中，上述S2034基於接收到的控制確認資訊向目標設備終端發送控制指令，具體包括：
在動態密碼集合中，查找是否存在與接收到的控制確認資訊對應的動態密碼，具體的，在接收到客戶端針對業務頁面發送的控制確認資訊後，再次判斷動態集合中是否存在對應的動態密碼；

若否，則向目標設備終端發送控制指令，或者向客戶端回傳第二提示資訊，以提示用戶是否重新向後台服務端發送設備控制請求；
具體的，由於在掃描圖形碼驗證階段驗證通過後，即設備控制請求中攜帶的目標動態密碼滿足預設時效性條件，如果客戶端在預設時間內針對業務頁面向後台服務端發送的控制確認資訊，本次設備控制請求對應的目標動態密碼應該是有效的，即在動態密碼集合中存在目標動態密碼，若在動態密碼集合中不存在目標動態密碼，則說明客戶端未在預設時間內針對業務頁面向後台服務端發送的控制確認資訊。

在20世紀90年代，對於一個技術的改進可以很明顯地區分是硬體上的改進（例如，對二極體、電晶體、開關等電路結構的改進）還是軟體上的改進（對於方法流程的改進）。然而，隨著技術的發展，當今的很多方法流程的改進已經可以視為硬體電路結構的直接改進。設計人員幾乎都透過將改進的方法流程編程到硬體電路中來得到相應的硬體電路結構。因此，不能說一個方法流程的改進就不能用硬體實體模組來實現。例如，可編程邏輯器件（Programmable Logic Device，PLD）（例如現場可編程閘陣列（Field Programmable Gate Array，FPGA））就是這樣一種積體電路，其邏輯功能由用戶對器件編程來確定。由設計人員自行編程來把一個數位系統“整合”在一片PLD上，而不需要請晶片製造廠商來設計和製作專用的積體電路晶片。而且，如今，取代手工地製作積體電路晶片，這種編程也多半改用“邏輯編譯器（logic compiler）”軟體來實現，它與程式開發撰寫時所用的軟體編譯器相類似，而要編譯之前的原始代碼也得用特定的編程語言來撰寫，此稱之為硬體描述語言（Hardware Description Language，HDL），而HDL也並非僅有一種，而是有許多種，如ABEL（Advanced Boolean Expression Language）、AHDL（Altera Hardware Description Language）、Confluence、CUPL（Cornell University Programming Language）、HD Cal、JHDL（Java Hardware Description Language）、Lava、Lola、My HDL、PALASM、RHDL（Ruby Hardware Description Language）等，目前最普遍使用的是VHDL（Very-High-Speed Integrated Circuit Hardware Description Language）與Verilog。本領域技術人員也應該清楚，只需要將方法流程用上述幾種硬體描述語言稍作邏輯編程並編程到積體電路中，就可以很容易得到實現該邏輯方法流程的硬體電路。
控制器可以按任何適當的方式實現，例如，控制器可以採取例如微處理器或處理器以及儲存可由該（微）處理器執行的計算機可讀程式代碼（例如軟體或韌體）的計算機可讀媒體、邏輯閘、開關、專用積體電路（Application Specific Integrated Circuit，ASIC）、可編程邏輯控制器和嵌入微控制器的形式，控制器的例子包括但不限於以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20 以及Silicone Labs C8051F320，記憶體控制器還可以被實現為記憶體的控制邏輯的一部分。本領域技術人員也知道，除了以純計算機可讀程式代碼方式實現控制器以外，完全可以透過將方法步驟進行邏輯編程來使得控制器以邏輯閘、開關、專用積體電路、可編程邏輯控制器和嵌入微控制器等的形式來實現相同功能。因此這種控制器可以被認為是一種硬體部件，而對其內包括的用於實現各種功能的裝置也可以視為硬體部件內的結構。或者甚至，可以將用於實現各種功能的裝置視為既可以是實現方法的軟體模組又可以是硬體部件內的結構。

For a clear and complete description, it is obvious that the described embodiments are only a part of one or more embodiments in this specification, rather than all of the embodiments. Based on one or more of the embodiments in this specification, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the scope of protection of one or more of this specification.
One or more embodiments of this specification provide a scanning code control method, device and system. Since the graphic code displayed on the device terminal is dynamically changing, the dynamic password uploaded by the client should have a certain timeliness, so that it can use The timeliness of the dynamic password identifies whether the client is attacked, and in response to the situation where the client is identified as being illegally attacked by a malicious user, effective control is carried out in time to avoid unnecessary losses to normal users.
Figure 1 is a schematic diagram of the application scenario of the code scanning control system provided by one or more embodiments of this specification. As shown in Figure 1, the control system includes: a background server, a client, and a device terminal, where the client can be For mobile terminals such as smart phones and tablet computers, the back-end server can be a back-end server that is used to manage and control the device terminal and has a saas service. The device terminal can be a scan code to sell equipment, scan code to rent products, etc., Among them, the specific process of scanning code control is:
First, the client sends a device control request to the background server, where the device control request carries the target dynamic password;
Specifically, the client can be a device control request based on actively scanning the graphic code on the device terminal, which is a normal active request to control the device terminal; the client can also be triggered by a malicious user through illegal means. The issued device control request, that is, passively request to control the device terminal after being attacked;
Then, after receiving the above device control request, the background server determines whether the target dynamic password carried in the device control request meets the preset timeliness condition;
Specifically, in the case of a device control request issued by the client based on a code scanning operation on the graphic code on the device terminal, the target dynamic password carried in the device control request is valid; because the graphic code displayed on the device terminal corresponds to The dynamic password is dynamically updated. It takes a certain amount of time for a malicious user to obtain a dynamic password and then trigger a normal user to send a device control request carrying the dynamic password to the back-end server. Therefore, it takes a certain amount of time for the client to be triggered by the malicious user through illegal means. In the case of a device control request, the target dynamic password carried in the device control request is invalid;
Finally, the background server executes corresponding control operations according to the timeliness of the target dynamic password judgment result;
Specifically, when it is determined that the target dynamic password is valid, it means that the client is normally actively requesting control of the device terminal from the background server. At this time, the background server needs to respond to the device control request normally and control the device terminal to perform corresponding control actions; When it is determined that the target dynamic password is invalid, it means that the client is being attacked and requests the back-end server to control the device terminal. At this time, the back-end server needs to send back prompt information to the client, so as to implement illegal attacks against malicious users.

Fig. 2 is a schematic diagram of the first flow chart of the code scanning control method provided by one or more embodiments of this specification. The method in Fig. 2 can be executed by the backend server in Fig. 1. As shown in Fig. 2, the method at least includes The following steps:
S201: Receive a device control request sent by a client, where the device control request carries a target dynamic password;
Specifically, the device control request received by the back-end server may be sent by the client based on actively scanning the graphic code on the device terminal, that is, the client normally actively requests to control the device terminal; it may also be the client's active request to control the device terminal. Triggered by a malicious user through illegal means, it is a passive request to control the device terminal after the client is attacked;
S202: Determine whether the target dynamic password carried in the device control request meets the preset timeliness condition, where the target dynamic password corresponds to the dynamically updated graphic code displayed on the terminal of the target device in a one-to-one correspondence, that is, in the scanning graphic code verification stage, Determine the timeliness of the target dynamic password to identify whether there is a situation where the user is attacked. For the case where the device terminal is a scan code to sell the device, the scan graphic code verification phase is the process of the user using the client to scan the graphic code to request the opening page ；
Specifically, in the case of a device control request issued by the client based on a code scanning operation on the graphic code on the device terminal, the target dynamic password carried in the device control request satisfies the preset timeliness condition, that is, the target dynamic password corresponds to The graphic code is not invalid, and the dynamic password corresponding to the graphic code displayed on the device terminal is the target dynamic password;
In the case of a device control request sent by the client by a malicious user through illegal means, the target dynamic password carried in the device control request does not meet the preset timeliness condition, that is, the graphic code corresponding to the target dynamic password has expired. At this time, the dynamic password corresponding to the graphic code displayed on the device terminal is not the target dynamic password;
S203: Perform a corresponding control operation according to the timeliness judgment result for the target dynamic password, where the judgment result may be that the target dynamic password meets the preset timeliness condition, or the target dynamic password does not meet the preset timeliness condition;
Specifically, if the target dynamic password satisfies the preset timeliness condition, it means that the client is normal and actively requests the back-end server to control the device terminal. At this time, the back-end server needs to respond to the device control request normally and control the device terminal to perform corresponding control. Action; if the target dynamic password does not meet the preset timeliness condition, it means that the client is attacked and requests the back-end server to control the device terminal. At this time, the back-end server needs to send back prompt information to the client, for example, trigger the client Display the error page.
In one or more embodiments of this specification, the graphic code displayed on the device terminal is dynamically updated through the background server control. Since the graphic code displayed on the device terminal changes dynamically, the dynamic password uploaded by the client should have a certain time limit. In this way, the timeliness of the dynamic password can be used to identify whether the client is attacked, and effective control can be carried out in time to avoid unnecessary losses to normal users when the client is identified as being illegally attacked by malicious users.

Correspondingly, after the background server receives the confirmation control information, the control device terminal executes the corresponding control action;
If the judgment result is no, execute S2032 to return the first prompt information to the client, so that the client prompts based on the first prompt information;
Specifically, for the case where the judgment result is negative, that is, the target dynamic password does not meet the preset timeliness condition, it means that the client is attacked and requests the back-end server to control the device terminal. At this time, the back-end server needs to return to the client. Send the first prompt information to remind the user that there is currently a possibility of being attacked. In addition, you can also provide the option to confirm the submission of the device control request on the display page of the first prompt information displayed on the client side, for example, provide manual submission to open the door The requested option to prevent the problem of unable to trade when the uploaded target dynamic password becomes invalid due to the delay of the client's scanning code.
Furthermore, in order to further improve the accuracy of device control, the business data used to render the business page can also be returned to the client first, so that the user can send confirmation control information to the client based on the business page displayed by the client.

Specifically, the dynamic password can be stored in the key-value database (ie redis);
S205: Generate graphic code information according to the determined dynamic password, where the graphic code information can be obtained by splicing a preset URL address and a dynamic password, that is, the dynamic password can be added to the end of the URL address, for example, the URL The address can be https://alipay.com/detail.htm;
S206: Send the generated graphic code information to the target device terminal, so that the target device terminal displays the corresponding graphic code based on the graphic code information. The dynamic password generated each time is different, so the graphic code information Each is different, so that the graphic code displayed on the device terminal is dynamically updated. The graphic code can be a two-dimensional code or a barcode;
Specifically, in order to reduce the manufacturing cost of the device terminal, the electronic ink label screen can be used as the graphic code display screen. For example, the display screen for displaying the graphic code provided on the device terminal can be reused.

Further, in order to improve the judgment efficiency and judgment accuracy of the timeliness of the target dynamic password, the invalid dynamic password can be automatically deleted, and then after receiving the device control request, it is determined whether there is the target dynamic password carried in the device control request. , So as to determine whether the target dynamic password meets the preset timeliness condition. Based on this, as shown in FIG. 6, after sending the generated graphic code information to the target device terminal in S206, it also includes:
S207. Add the determined dynamic password to the dynamic password set, and when any dynamic password meets a preset destruction condition, remove the dynamic password from the dynamic password set, where the preset destruction condition includes: The password reaches the preset survival time and/or the dynamic password has been used. Specifically, the dynamic password reaches the preset survival time means that the inventory time of the dynamic password is greater than the preset aging threshold, that is, the dynamic password expires and is destroyed, and the dynamic password has been used means that it has been used. Device terminal control is performed on the dynamic password, that is, the dynamic password has been used and destroyed, wherein the dynamic password set includes at least one valid dynamic password, and the dynamic password set is set in the key-value database (ie redis);
Correspondingly, the foregoing S202 determines whether the target dynamic password carried in the device control request meets the preset timeliness condition, which specifically includes:

If the judgment result is yes, it is determined that the target dynamic password meets the preset timeliness condition, and the above-mentioned S2031 is executed to return the service page to the client, so that the client requests the background server to control the target device terminal based on the service page;
If the judgment result is negative, it is determined that the target dynamic password does not meet the preset timeliness condition, and the above-mentioned S2032 is executed to return the first prompt information to the client, so that the client prompts based on the first prompt information.
Specifically, when a certain dynamic password is removed from the dynamic password set, it means that the graphic code corresponding to the dynamic password becomes invalid, and the image code displayed on the corresponding device terminal needs to be updated. Based on this, the above S207 changes After the dynamic password is removed from the dynamic password collection, it also includes:
Generate a new dynamic password, and update the corresponding graphic code displayed on the target device terminal based on the new dynamic password;

In the 1990s, the improvement of a technology can be clearly distinguished from the improvement of the hardware (for example, the improvement of the circuit structure of diodes, transistors, switches, etc.) or the improvement of the software (for the process of the method). Improve). However, with the development of technology, the improvement of many methods and processes of today can be regarded as a direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by the hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user's programming of the device. It is programmed by the designer to "integrate" a digital system on a PLD without requiring the chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly realized by using "logic compiler" software, which is similar to the software compiler used in program development and writing, but compiles The original code before has to be written in a specific programming language, which is called Hardware Description Language (HDL), and HDL is not only one, but there are many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HD Cal, JHDL (Java Hardware Description Language), Lava, Lola, My HDL, PALASM, RHDL (Ruby Hardware Description Language), etc., Currently the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that only a little logic programming of the method flow in the above hardware description languages and programming into the integrated circuit can easily obtain the hardware circuit that implements the logic method flow.
