uniapp微信分享

一、注册微信开发平台

1、app分享需要先到微信开放平台注册应用，并获得开放平台的 appId和秘钥

2、配置开发者信息如下图

 

3、安卓版的应用签名生成

3.1 打包好uniApp的安卓版本，并安装到手机上（打包配置）

3.2 选择文件下载，并安装到安卓手机上

下载地址：https://developers.weixin.qq.com/doc/oplatform/Downloads/Android_Resource.html

3.3 安装好下载的软件后，打开输入第二步配置的包名生成秘钥，再把秘钥配置到第二步里

二、uni-app 安卓版本打包

1、模块配置

打开HBuilder X 开发工具，如下图操作步骤操作，其中appid 是第一步在开放平台注册之后生成的

 

2、云打包配置

2.1 生成自有证书

2.2 共有证书

开发测试的时候可以使用，正式环境不能使用

2.3 云打包配置

 

3、查看证书命令

在cmd 命令窗口中输入  keytool -list -v -keystore community.keystore

三、分享代码

文档：https://uniapp.dcloud.io/api/plugins/share?id=onshareappmessage

 1、小程序分享

JavaScript // 小程序分享   shareMini() {                 uni.share({                         provider: 'weixin',                         scene: "WXSceneSession",                         type: 5,                         imageUrl: 'https://bjetxgzv.cdn.bspapp.com/VKCEYUGU-uni-app-doc/962fc340-4f2c-11eb-bdc1-8bd33eb6adaa.png',                         title: '打开APP测试',                         miniProgram: {                                 id: 'gh_60e75c691915',                                 path: 'pages/work/work',                                 type: 0,                                 webUrl: 'http://uniapp.dcloud.io'                         },                         success: ret => {                                 console.log(JSON.stringify(ret));                         }                 }); },

2、图文分享

JavaScript // 图文分享   shareImgTex() {                 uni.share({                         provider: "weixin",                         scene: "WXSceneSession",                         type: 0,                         href: "http://uniapp.dcloud.io/",                         title: "加入社群邀请",                         summary: "民警-张丽邀请你加入社群",                         imageUrl: "/static/images/code.png",                         success: function(res) {                                 console.log("success:" + JSON.stringify(res));                         },                         fail: function(err) {                                 console.log("fail:" + JSON.stringify(err));                         }                 }); },

3、图片分享

JavaScript // 图片分享   shareImg() {                 uni.share({                         provider: "weixin",                         scene: "WXSceneSession",                         type: 2,                         imageUrl: "/static/images/code.png",                         success: function(res) {                                 console.log("success:" + JSON.stringify(res));                         },                         fail: function(err) {                                 console.log("fail:" + JSON.stringify(err));                         }                 }); },

四、微信打开APP

1、H5 页面打开APP

 文档：https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_H5_Launch_APP.html

2、小程序打开APP

文档：https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/launchApp.html

注意：打开需要特定的场景值，也就是说只有app 分享（小程序类型的分享） 到微信聊天的卡片点击进入小程序才能跳转到APP内

小程序打开APP的代码：

Scala <button class="margin-top" open-type="launchApp" size="default" type="primary" app-parameter="wechat" :binderror="launchAppError()">打开APP</button>

3、uniapp 打开小程序

JavaScript //打开微信小程序 ，appId:小程序原始ID,path跳转的小程序页面 openWxMiniApp(appId, path) {                 plus.share.getServices(function(res) {                         var sweixin = null;                         for (var i = 0; i < res.length; i++) {                                 var t = res[i];                                 if (t.id == 'weixin') {                                         sweixin = t;                                 }                         }                         if (sweixin) {                                 // 发送分享                                 if(sweixin.authenticated){                                         sweixin.launchMiniProgram({                                                 id: appId,                                                 type: 0,                                                 path: path || ''                                         });                                 }else {                                         sweixin.authorize(function(){                                                 doShare(sweixin, msg);                                         }, function(e){                                                 // code   错误码   http://ask.dcloud.net.cn/article/282                                                 uni.showToast({                                                         title: e?.code === -8 ? '微信客户端未安装' : e?.message,                                                         icon: 'none'                                                 })                                         });                                 }                         } else {                                 uni.showToast({                                         title: '打开小程序失败',                                         icon: 'none'                                 })                         }                 }, function(res) {                         console.log(JSON.stringify(res));                         uni.showToast({                                 title: '打开小程序失败',                                 icon: 'none'                         })                 });         },
