HarmonyOS 如何获取用户设备系统字体信息？

import font from '@ohos.font';  
@Entry  
@Component  
struct FontExample {  
  build() {  
    Column() {  
      Button("getUIFontConfig")  
        .width('60%')  
        .height('6%')  
        .margin(50)  
        .onClick(()=>{  
          let fontConfig = font.getUIFontConfig();  
          console.log("font-dir -----------" + String(fontConfig.fontDir.length));  
          for (let i = 0; i < fontConfig.fontDir.length; i ++) {  
            console.log(fontConfig.fontDir[i]);  
          }  
          console.log("generic-------------" + String(fontConfig.generic.length));  
          for (let i = 0; i < fontConfig.generic.length; i ++){  
            console.log("family:" + fontConfig.generic[i].family);  
            for (let j = 0; j < fontConfig.generic[i].alias.length; j ++){  
              console.log(fontConfig.generic[i].alias[j].name + " " + fontConfig.generic[i].alias[j].weight);  
            }  
            for (let j = 0; j < fontConfig.generic[i].adjust.length; j ++){  
              console.log(fontConfig.generic[i].adjust[j].weight + " " + fontConfig.generic[i].adjust[j].to);  
            }  
          }  
          console.log("fallback------------" + String(fontConfig.fallbackGroups.length));  
          for (let i = 0; i < fontConfig.fallbackGroups.length; i ++){  
            console.log("fontSetName:" + fontConfig.fallbackGroups[i].fontSetName);  
            for (let j = 0; j < fontConfig.fallbackGroups[i].fallback.length; j ++){  
              console.log("language:" + fontConfig.fallbackGroups[i].fallback[j].language + " family:" + fontConfig.fallbackGroups[i].fallback[j].family);  
            }  
          }  
        })  
    }.width('100%')  
  }  
}
