video.wxml 页面


<form bindsubmit='upload'>

<view class="inputView">

            <label class="loginLabel">视频描述：</label>

            <input name="desc" class="inputText" placeholder="说点什么吧" />

        </view>

        <!-- 提交 -->

        <button class="submitBtn" type="primary" form-type='submit'>上传视频</button>



        <button class="gobackBtn" type="warn" form-type='reset'>重置</button>

    </form>

在video.js里定义video.wxml 页面 <form bindsubmit='upload'>upload方法

 upload: function(e){
      var me = this;
      var bgmId = e.detail.value.bgmId;
      var desc = e.detail.value.desc;
      var duration = me.data.videoParams.duration;
      var tmpHeight = me.data.videoParams.tmpHeight;
      var tmpWidth = me.data.videoParams.tmpWidth;
      var tmpVideoUrl = me.data.videoParams.tmpVideoUrl;
      var tmpCoverUrl = me.data.videoParams.tmpCoverUrl;

      //上传短视频
      wx.showToast({
        title: '上传中...',
      })
var serverUrl = app.serverUrl;

wx.uploadFile({

        url: serverUrl + '/video/upload',

        formData: {

          userId: app.userInfo.id,

          bgmId: bgmId,

          desc: desc,

          videoSeconds: duration,

          videoHeight: tmpHeight,

          videoWidth: tmpWidth

        },

        filePath: tmpVideoUrl,

        name: 'file',

        header: {

          'content-type': 'application/json', // 默认值

        },

        success(res) {

          var data = JSON.parse(res.data);

          console.log(res);

          wx.hideLoading();

          if (data.status == 200) {

            wx.showToast({

              title: '上传成功',

              icon: 'success',

              duration: 3000,

            });

          }

        }
