鸿蒙多环境配置

1、工程级目录build-profile.json5

{
    "app": {
        "signingConfigs": [
            {

                        }
                    }
                }
            },
            {

                        }
                    }
                }
            }
        ],
        "buildModeSet": [

                "name": "release"
            }
        ]
    },
    "modules": [
        {

            ]
        },

        {
            "name": "library",
            "srcPath": "./library"
        }
    ]
}

　　2、entry中 build-profiles.json5

{
    "apiType": "stageMode",
    "buildOption": {
        "externalNativeOptions": {
            "abiFilters": ["arm64-v8a", "x86_64"]
        }
    },
    "buildOptionSet": [
        {
            "name": "release",
            "arkOptions": {
                "obfuscation": {
                    "ruleOptions": {
                        "enable": true,
                        "files": [
                            "./obfuscation-rules.txt"
                        ]
                    }
                }
            }
        },
    ],
    "targets": [
        {
            "name": "default"
        },
        {
            "name": "prod",
        }
    ]
}

4、代码示例

import Config from '../../util/Config';
import { IndexComponent } from './IndexComponent';  // 确保路径正确
import { MyComponent } from './MyComponent';  // 确保路径正确
import BuildProfile from 'BuildProfile'
@Builder
export function HomeBuilder() {
    Home()
}

PersistentStorage.persistProp("user_id", undefined)

@Entry
@Component
struct Home {
    @State selectedIndex: number = 0;
    pathStack: NavPathStack = new NavPathStack();
    aboutToAppear(): void {
        console.log('1111111')
        console.log(BuildProfile.NEWS_DETAIL)
        console.log('2222222222')
    }
    build() {
        Navigation(this.pathStack) {
            Tabs({ barPosition: BarPosition.End ,index: this.selectedIndex}){
                TabContent() {
                    IndexComponent({pathStack:this.pathStack});
                }.tabBar(
                    new BottomTabBarStyle(this.selectedIndex === 0 ? $rawfile('index.png') : $rawfile('index2.png'), '首页')
                        .labelStyle({
                            selectedColor: this.selectedIndex === 0 ? '#58b8fe':'#a4a4a4',
                            unselectedColor: '#a4a4a4'
                        })

                }.tabBar(
                    new BottomTabBarStyle(this.selectedIndex === 1 ? $rawfile('my.png') : $rawfile('my2.png'), '我的')
                        .labelStyle({
                            selectedColor: this.selectedIndex === 1 ? '#58b8fe':'#a4a4a4',
                            unselectedColor: '#a4a4a4'
                        })
                )

            }
            .onChange((index: number) => {
                console.log('index:',index)
                this.selectedIndex   = index
            })
        }
        .titleMode(NavigationTitleMode.Mini).hideTitleBar(true)
