【项目转让/可二开】已上线人才×项目撮合平台｜完整前后端+管理后台，可直接部署运营

正文：

手上有一套已经开发完成并上线的人才/项目双边撮合平台，目前准备整体转让，也接受基于现有系统做二次开发。

当前业务场景是：项目方发布需求 → 程序员/服务方入驻 → 平台审核 → 人工匹配撮合 → 跟进项目。

不是单独卖一个前端模板，项目包含完整的：

Web 前端
后端服务
管理后台
数据库结构
用户/需求等核心业务模块
部署配置
已上线域名及现有项目资产（具体交接范围可谈）

系统目前做的是程序员项目撮合，但底层属于双边供需平台，因此也可以继续二开成：

兼职招聘 / 灵活用工 / 自由职业 / 企业服务 / 本地服务 / 技术外包 / 供需撮合等平台。

为什么转让

个人精力和后续发展方向调整，不准备继续长期运营，所以考虑把完整项目交给真正有需求的人继续做。

适合谁
正准备开发人才、兼职、灵工、接单、撮合类产品的人；
想直接拿现成系统二开，不想从0开发的人；
有获客/运营能力，但缺技术产品的团队；
软件公司/工作室，可作为现成项目底座继续开发。
合作方式

A：整套项目独家转让

完成交易后按照约定交接源码、数据库、后台及部署资料等，不是单纯多份源码授权。

B：基于现有系统二开

如果你正好有类似项目需求，但不想直接买整套，也可以把需求发给我，可以在现有系统基础上修改。

有兴趣可以私聊我，先看线上 Demo 和后台，再决定是否继续谈

• 2020年chromium 83之后不再兼容4.4，app端js engine一直停在基于83的版本。uniapp应该提供“现代”的js引擎，让开发者能按需选择

• 更灵活的针对vue3 patch的方式，让开发者能按需使用，或者定期跟进vue 3 大版本

• vite vue3分包下打包到app，依然还是将js合到一个大的app-service.js中，分包的css也不支持手动配置优化。应该能按照vite的打包配置，拆分（js/css）到各个chunk，应用启动时只加载首页资源，同时可以利用类似link prefetch/module preload的特性，让开发者能按需预载其它页面需要的（静态）资源。以达到最高的加载效率

• uniapp目前还在用着老旧的vite/sass版本，但在cli项目中手动更新至vite 7/sass 1.100 其实是能正常运行的，只是组件库基本都因为过时方式导致过多sass警告信息

。。。

分享一下之前的版本

uniappx 基础脚手架，包含功能：

1. 基础简单的登录示例代码
2. request请求封装
3. 跳转 + 登录白名单/拦截
4. 版本更新(多渠道，应用市场， 蒲公英分发或第三方链接等平台)
5. 文件的上传下载
6. 图像裁剪上传封装
7. 主题的切换，包括明暗主题与自定义主题等

使用pageTransition函数实现页面转场效果。通过PageTransitionEnter和PageTransitionExit指定页面进入和退出的动画效果。将slide属性设置为SlideEffect.Bottom，页面入场时从下方滑入，出场时滑出到下方，从而实现上下切换效果。参考代码如下：

// Index.ets
@Entry
@Component
struct PageTransition1 {
pageInfos: NavPathStack = new NavPathStack();

build() {
Stack({ alignContent: Alignment.Bottom }) {
Navigation(this.pageInfos) {
Image($r('app.media.ic_banner01')).width('100%').height(200) // The image is stored in the media folder
}
}.height('100%').width('100%')
}

pageTransition() {
PageTransitionEnter({ duration: 500, curve: Curve.Linear }).slide(SlideEffect.Bottom)
PageTransitionExit({ duration: 500, curve: Curve.Ease }).slide(SlideEffect.Bottom)
}
}
// Page1.ets
@Entry
@Component
struct PageTransition2 {
pageInfos: NavPathStack = new NavPathStack();

build() {
Stack({ alignContent: Alignment.Bottom }) {
Navigation(this.pageInfos) {
Image($r('app.media.ic_banner02')).width('100%').height(200) // The image is stored in the media folder
}
}.height('100%').width('100%')
}

pageTransition() {
PageTransitionEnter({ duration: 500, curve: Curve.Linear }).slide(SlideEffect.Bottom)
PageTransitionExit({ duration: 500, curve: Curve.Ease }).slide(SlideEffect.Bottom)
}
}

问题现象
按键子项生成气泡效果用什么组件实现好？

效果预览
点击放大

背景知识
使用自定义键盘实现官网示例代码进行自定义键盘调试，然后用LongPressGesture增加长按手势事件，最后使用Popup控制为组件绑定Popup气泡，使用Popup气泡，如果按键处于边缘位置，组件会自动偏移，完整的显示在屏幕中间。

解决方案
自定义键盘没有直接长按生成气泡的接口，需要自定义长按逻辑，手指在长按小键盘组件时，使用Popup生成一个气泡，在气泡生成之后，使用onTouch获取手指位置并且根据气泡组件的位置和横向大小，计算当前手指划过的距离从而标记手指当前选择的内容。

代码实现思路如下：

创建变量控制气泡显隐样式以及气泡在边缘的位置：
@State customPopup: boolean = false;
@State indexNum: number = 0;
// 手指位置1、2、3、4（长按气泡中显示的内容数量）四个参数，分别代指长按后出现的四个位置，参数值与实际业务有关。
@State fingerRect: string = '1';
// 组件宽度
@State widthRect: number = 0;
// 键盘宽度
@State inputWidthRect: number = 0;
// 判断是否在偏右侧位置
@State isRight: boolean = false;
增加LongPressGesture长按控制手势，在onAction事件中增加逻辑，让气泡仅显示在指定按键上方；长按手势默认最短长按时间为500毫秒，可配置duration参数控制最短长按时长：
.gesture(
// 绑定可以重复触发的LongPressGesture
LongPressGesture({ repeat: true })
.onAction(() => {
for (let i = 0; i < EnglishKeyboardData[0].length; i++) {
if (item.text === EnglishKeyboardData[0][i].text) {
this.indexNum = i;
break;
}
}
this.customPopup = true;
})
.onActionEnd(() => {
this.customPopup = !this.customPopup;
})
)
增加bindPopup气泡控制，设置placement: Placement.TopRight,让气泡显示在按钮上方，通过this.popupBuilder(item)给自定义气泡组件传参然后自定义气泡内容：
.bindPopup(this.customPopup && EnglishKeyboardData[0].indexOf(item) === this.indexNum, {
// CustomPopupOptions类型气泡的内容
builder: this.popupBuilder(item),
placement: Placement.TopLeft,
targetSpace: '15vp',
enableArrow: false,
onStateChange: (e) => {
if (!e.isVisible) {
this.customPopup = false;
}
}
})
@Builder
popupBuilder(item: Menu) {
Row() {
ForEach([1, 2, 3, 4], (num: number, index: number) => {
if (this.fingerRect === index + 1 + '') {
Row() {
Text(item.text + '' + num)
.fontColor(Color.White);
}
.globalFancy()
.backgroundColor(Color.Blue)
.justifyContent(FlexAlign.Center);
} else {
Row() {
Text(item.text + '' + num);
}
.globalFancy()
.justifyContent(FlexAlign.Center);
}
}, (num: number) => JSON.stringify(num));
}
.height(50)
.width(150)
.padding(5)
.justifyContent(FlexAlign.SpaceAround)
.onAreaChange((oldVal, newVal) => {
// 如果此时键盘在偏右侧位置，需要重新计算位置
this.isRight = this.inputWidthRect <= Math.ceil(Number(newVal.globalPosition.x) + Number(newVal.width));
});
}
使用onAreaChange监听新生成的气泡组件的宽度，再使用onTouch事件获取当前手指的坐标，然后根据手指的坐标和气泡组件的宽度，获取当前手指在气泡组件中的位置：
.onTouch((event) => {
// 获取当前手指的坐标（相对于父容器，与组件rect的坐标系一致）
const fingerX = event.touches[0].x;
// 靠近右边屏幕时，需要特殊处理。
this.fingerRect =
this.isRight ? Math.ceil(((fingerX + event.touches[0].displayX) - 230) / this.widthRect) + '' :
Math.ceil(fingerX / this.widthRect) + '';
this.fingerRect =
(Number(this.fingerRect) <= 1) ? '1' : Number(this.fingerRect) >= 4 ? '4' : this.fingerRect;
})
.onAreaChange((oldVal, newVal) => {
this.widthRect = Number(newVal.width);
});
参考官网自定义键盘实现，将demo中的NumberKeyboard文件替换为以下示例代码：

// 该场景代码基于自定义键盘实现官网示例代码https://developer.huawei.com/consumer/cn/doc/best-practices/bpta-custom-keyboard#section1680905412256进行调试；
// 修改demo中NumberKeyboard文件如下
@Component
export struct NumberKeyboard {
@State customPopup: boolean = false;
@State indexNum: number = 0;
// 手指位置1、2、3、4（长按气泡中显示的内容数量）四个参数，分别代指长按后出现的四个位置，参数值与实际业务有关。
@State fingerRect: string = '1';
// 组件宽度
@State widthRect: number = 0;
// 键盘宽度
@State inputWidthRect: number = 0;
// 判断是否在偏右侧位置
@State isRight: boolean = false;

使用getTarget接口获取状态管理框架代理前的原始对象。

参考示例如下：

import { UIUtils } from '@kit.ArkUI';

@Observed
class UserInfo {
name: string = 'Tom';
}

@Entry
@Component
struct GetTargetDemo {
@State info: UserInfo = new UserInfo();

build() {
Column() {
Text(info.name: ${this.info.name})
Button('Change the properties of the proxy object')
.onClick(() => {
this.info.name = 'Alice'; // The Text component can refresh
})
Button('更改原始对象的属性')
.onClick(() => {
let rawInfo: UserInfo = UIUtils.getTarget(this.info);
if (rawInfo) {
rawInfo.name = 'Bob'; // The Text component cannot be refreshed
}
})
}
}
}

问题描述

运行下面demo，点击使色块消失时，会突然出现在左上角闪烁。

@Entry
@ComponentV2
struct Index {
@Local isShow: boolean = true;

build() {
Stack() {
Stack() {
if (this.isShow) {
Row()
.width(100)
.height(100)
.backgroundColor(Color.Red)
.transition(TransitionEffect.OPACITY.animation({ duration: 150 }));
}
}
.backgroundColor(Color.Green)
}
.width('100%')
.height('100%')
.onClick(() => {
this.isShow = !this.isShow;
});
}
}
解决措施

原因是当变量置为false时，组件会从视图树中移除，导致内层Stack失去内容后位置重置到左上角，可以固定内层Stack组件的宽高来避免，示例如下：

@Entry
@ComponentV2
struct DisappearanceAnimationOffsetFlicker {
@Local isShow: boolean = true;

build() {
Stack() {
Stack() {
if (this.isShow) {
Row()
.width(100)
.height(100)
.backgroundColor(Color.Red)
.transition(TransitionEffect.OPACITY.animation({ duration: 150 }))
}
}
.width('100%')
.height('100%')
.onClick(() => {
this.isShow = !this.isShow
})
}
}
}
