<pre class="brush:javascript;gutter:true;">### 第一步配置APP更新接口
在`APPUpdate.js`里面`getServerNo`函数方法配置更新接口
```
let httpData = {
version:version
};
if (platform == "android") {
httpData.type = 1101;
} else {
httpData.type = 1102;
}
/* 接口入参说明
* version: 应用当前版本号（已自动获取）
* type：平台（1101是安卓，1102是IOS）
*/
$http.get("api/kemean/aid/app_version", httpData).then(res => {
/*接口出参说明 （res数据说明）
* | 参数名称 | 一定返回 | 类型 | 描述
* | -------------|--------- | --------- | ------------- |
* | versionCode | y | int | 版本号 |
* | versionName | y | String | 版本名称 |
* | versionInfo | y | String | 版本信息 |
* | forceUpdate | y | boolean | 是否强制更新|
* | downloadUrl | y | String | 版本下载链接 `IOS安装包更新请放跳转store应用商店链接,安卓apk和wgt文件放文件下载链接` |
*/
});
```
### 第二步 使用方法
```
// App.vue页面
// #ifdef APP-PLUS
import APPUpdate from "@/utils/APPUpdate";
// #endif
onLaunch: function(e) {
// #ifdef APP-PLUS
APPUpdate();
// #endif
}
```
### 第三步 添加APP安装应用的权限
在`manifest.json`文件里面`APP模块权限配置`的`Android打包权限配置`勾选以下权限
```
<uses-permission android:name=\"android.permission.INSTALL_PACKAGES\"/>
<uses-permission android:name=\"android.permission.REQUEST_INSTALL_PACKAGES\"/>
```
### 修改弹窗的主题色或弹窗图标
在`APPUpdate.js`里面上面`$mainColor`常量中定义主题颜色，`$iconUrl`常量中定义图标地址
### 检查APP是否有新版本（一般在设置页面使用）
```
// #ifdef APP-PLUS
import APPUpdate, { getCurrentNo } from "@/utils/APPUpdate";
// #endif
export default {
data() {
return {
version: "" // 版本号
};
},
//第一次加载
onLoad(e) {
// #ifdef APP-PLUS
getCurrentNo(res => {
// 进页面获取当前APP版本号（用于页面显示）
this.version = res.version;
});
// #endif
},
//方法
methods: {
// 检查APP是否有新版本
onAPPUpdate() {
// true 没有新版本的时候有提示，默认：false
APPUpdate(true);
}
}
}
```
