示例：微信小程序获取设备信息的API
微信小程序获取设备信息可以使用`wx.getSystemInfoSync()`方法。这个方法会同步返回一个对象，包含了设备的基本信息，如屏幕宽度、高度、像素密度等。示例代码如下： ```javascript const systemInfo = wx.getSystemInfoSync(); console.log(systemInfo); ``` 在控制台可以看到类似以下输出： ```json { "brand": "Apple", "model": "iPhone X", "platform": "iOS", "version": "13.2.3", "language": "zh_CN", "fontSizeSetting": "medium", "screenWidth": 375, "screenHeight": 812, "pixelRatio": 3, "deviceToken": "", "appName": "微信", "appVersion": "7.0
