　　微信小程序開發中的數據分享和數據傳遞主要通過以下方式實現，具體方法及適用場景如下：
　　The data sharing and transmission in WeChat mini program development are mainly achieved through the following methods, and the specific methods and applicable scenarios are as follows:

　　一、數據分享
　　1、 Data Sharing
　　通過URL參數傳遞
　　Passing through URL parameters
　　在頁面跳轉時，通過URL的query參數傳遞數據（如/pages/detail/detail？productId=123），目標頁面在onLoad函數中通過options參數獲取。
　　When jumping to a page, pass data through the query parameter of the URL (such as/pages/detail/detail?)? productId=123）， The target page is obtained through the options parameter in the onLoad function.
　　分享給好友/轉發
　　Share with friends/forward
　　使用onShareAppMessage方法自定義分享內容，可設置分享標題、路徑等。
　　Use the onShareAppMessage method to customize the shared content, including setting the sharing title, path, and more.
　　在app.json中配置可轉發的頁面，支持攜帶參數轉發。
　　Configure pages that can be forwarded in app.json and support parameter forwarding.
　　二、數據傳遞
　　2、 Data transmission
　　全局變量傳遞
　　Global variable passing
　　通過getApp（）.globalData在app.js中定義全局變量，不同頁面可共享數據（如用戶信息、配置等）。
　　Define global variables in app. js through getApp(). GlobalData, allowing different pages to share data (such as user information, configuration, etc.).
　　本地存儲（Storage API）
　　Local Storage (Storage API)
　　同步存儲 ：wx.setStorageSync用于設置數據，wx.getStorageSync獲取。
　　Synchronous storage: wx.setWarehousSync is used to set data, while wx.getWarehousSync retrieves it.
　　異步存儲 ：wx.setStorage和wx.getStorage用于非阻塞操作。
　　Asynchronous storage: wx.setStorage and wx.getStorage are used for non blocking operations.
　　數據庫共享
　　Database sharing
　　通過微信云開發提供的數據庫API，實現跨小程序的數據存儲與共享。
　　Through the database API provided by WeChat Cloud Development, data storage and sharing across mini programs can be achieved.
　　頁面棧與事件傳遞
　　Page Stack and Event Passing
　　利用頁面棧的getCurrentPages（）方法獲取頁面路徑，實現跨頁面通信。
　　Utilize the getCurrentPages() method of the page stack to obtain the page path and achieve cross page communication.
　　通過自定義事件（如wx.triggerEvent）在組件間傳遞數據。
　　Pass data between components through custom events such as wx. triggerEvent.
　　三、注意事項
　　3、 Precautions
　　URL參數 ：適用于簡單數據傳遞，但存在安全風險且參數數量有限。
　　URL parameters: Suitable for simple data transfer, but there are security risks and the number of parameters is limited.
　　本地存儲 ：適合臨時數據，關閉小程序后數據會丟失。
　　Local storage: suitable for temporary data, data will be lost after closing the mini program.
　　數據庫 ：適合長期存儲和多用戶共享，需注意數據隱私。
　　Database: Suitable for long-term storage and multi-user sharing, data privacy should be taken into account.
　　選擇合適的方式需根據數據類型、使用場景及安全性需求決定。
　　The appropriate method should be determined based on the data type, usage scenario, and security requirements.
