微信开发的常用接口

1.监听摇一摇

var shakeOn =false;
function deviceMotionHandler(eventData,callback) {
            if(shakeOn === false){return}
            var acceleration = eventData.accelerationIncludingGravity;  
            var curTime = new Date().getTime();  
            if ((curTime - last_update) > 100) {  
                var diffTime = curTime - last_update;  
                last_update = curTime;  
                x = acceleration.x;  
                y = acceleration.y;  
                z = acceleration.z;  
                var speed = Math.abs(x + y + z - last_x - last_y - last_z) / diffTime * 10000;  
                if (speed > SHAKE_THRESHOLD) {
                    if(new Date() - lTime > _timeLimit){
                        lTime = new Date();
                                callback();
                    };
                }  
                last_x = x;
                last_y = y;
                last_z = z;
            }  
        }
    window.addEventListener('devicemotion', function(){
          deviceMotionHandler(eventData,callback)
        }, false); 

2.微信分享

1.请求拿到配置微信appId等信息的对象 （如下）
//wx.config ({  
    //debug : false,    // true:调试时候弹窗  
    //appId : $wx_account[0],  // 微信appid  
    //timestamp : $wx_account[1], // 时间戳  
    //nonceStr : $wx_account[2],  // 随机字符串  
    //signature : $wx_account[3], // 签名  
//});  

<script type="text/javascript">
var src = "http://xxx.com.cn/weixinJS.action?url="
+encodeURIComponent(location.href.split('#')[0]);
var left = unescape('%3c');
var right = unescape('%3E');
document.write(left + 'script src="' + src + '"' + right + left + '/script' + right);
</script>

function initWXShare() {
    wx.onMenuShareAppMessage({
        title: shareData.title,
        desc: shareData.desc,
        link: shareData.link,
        imgUrl: shareData.imgUrl
    }), wx.onMenuShareTimeline({
        title: shareData.title,
        desc: shareData.desc,
        link: shareData.link,
        imgUrl: shareData.imgUrl
    }), wx.onMenuShareQQ({
        title: shareData.title,
        desc: shareData.desc,
        link: shareData.link,
        imgUrl: shareData.imgUrl
    }), wx.onMenuShareWeibo({
        title: shareData.title,
        desc: shareData.desc,
        link: shareData.link,
        imgUrl: shareData.imgUrl
    })
}
var shareData = {
    imgUrl: "",
    link: "",
    title: "",
    desc: ""
};
//WXConfig是上方js请求回来的config对象
//添加配置需要使用的API ：分享到朋友圈，好友，qq，微博。。。
WXConfig.jsApiList = ["onMenuShareTimeline", "onMenuShareAppMessage", "onMenuShareQQ", "onMenuShareWeibo"], 

wx.config(WXConfig), //微信config配置文件
 wx.ready(initWXShare); //初始化添加分享信息

3.自动播放音频（否则只有触摸屏幕才会开始播放）

wx.ready(function () {
  wx.getNetworkType({
    success: function (res) {
      video.play()
    }
  })
})

4.录音及播放

//调用微信录音接口

            wx.startRecord({
                success: function success() {
                    START = new Date().getTime();
                    var i = 1;
                    var timer1 = setInterval(function () {
                        i += 1;
                        if (i == 60) {
                            clearInterval(timer1);
                        }
                    }, 1000);
                     
                    wx.onVoiceRecordEnd({
                    // 录音时间超过一分钟没有停止的时候会执行 complete 回调
                        complete: function complete(res) {
                            alert('最多只能录制一分钟');
                            localId = res.localId;
                        }
                    });
                },
                cancel: function cancel() {
                    alert('用户拒绝授权录音');
                    return false;
                }
            });

//调用录音结束接口

                wx.stopRecord({
                    success: function success(res) {
                        localId = res.localId;
                        wx.playVoice({ //播放用户的录音
                            localId: localId // 需要播放的音频的本地ID，由stopRecord接口获得
                        });
                        wx.translateVoice({ //语音识别功能，汉字比对，以读对字数的百分比计分。
                            localId: localId, // 需要识别的音频的本地Id，由录音相关接口获得
                            isShowProgressTips: 1, // 默认为1，显示进度提示
                            success: function success(res) {
                                var txt = res.translateResult; // 语音识别的结果
                                },
                            error: function error() {
                               
                            }
                        });
                });
