ionic 微信分享

先添加cordova插件：

$ cordova plugin add cordova-plugin-wechat --variable wechatappid=YOUR_WECHAT_APPID

controllers.js

app.controller('DashCtrl',  function($scope, $ionicActionSheet, $ionicPopup) {
  document.addEventListener("deviceready", onDeviceReady, false);

  function onDeviceReady() {
    console.log(Wechat);
    Wechat.isInstalled(function (installed) {
        alert("Wechat installed: " + (installed ? "Yes" : "No"));
    }, function (reason) {
        alert("Failed: " + reason);
    });
    var scope = "snsapi_userinfo",
        state = "_" + (+new Date());
    Wechat.auth(scope, state, function (response) {
        // you may use response.code to get the access token.
        alert(JSON.stringify(response));
    }, function (reason) {
        alert("Failed: " + reason);
    });
    // Add similar listeners for other events
  }////只是个小DEMO所以就直接登录微信了，如果需要单独登录稍微改一下就可以了

  $scope.share = function(title, desc, url, thumb) {
    $ionicActionSheet.show({
      buttons: [
        { text:'分享给微信好友' },
        { text:'分享至微信朋友圈' }
      ],
      titleText: '分享',
      cancelText:'取消',
      cancel: function() {
      // 取消时执行                
      },
      buttonClicked: function(index) {
        console.log(index);
        if(index == 0) {
          $scope.shareViaWechat(0, title, desc, url, thumb);
        }
        if(index == 1) {
          $scope.shareViaWechat(1, title, desc, url, thumb);
        }
      }
    }); 
  };
  $scope.shareViaWechat = function(scene, title, desc, url, thumb) {
    //scene:1 表示分享到朋友圈
    //scene:0 表示分享给好友
    console.log(scene);
    var msg = {
      title: "Hi, there",
      description: "This is description.",
      thumb: "www/img/pyq.png",
      mediaTagName: "TEST-TAG-001",
      messageExt: "这是第三方带的测试字段",
      messageAction: "<action>dotalist</action>",
      //media: "YOUR_MEDIA_OBJECT_HERE",
      //网页链接
      media: {
          type: Wechat.Type.WEBPAGE,
          webpageUrl: "http://tech.qq.com/zt2012/tmtdecode/252.htm"
      }
    }
    //分享文字
      // Wechat.share({
      //     text: "This is just a plain string",
      //     scene: Wechat.Scene.TIMELINE   // share to Timeline
      // }, function () {
      //     alert("Success");
      // }, function (reason) {
      //     alert("Failed: " + reason);
      // });
  //分享链接，设置好标题，描述，图片，链接 参数就OK。
    Wechat.share({
        message: msg,
        scene: scene   // share to Timeline
    }, function () {
        alert("Success");
    }, function (reason) {
        alert("Failed: " + reason);
    });
  };
})
