最近写一个后台系统需要用到视频上传,在百度找了一番后最终实现了。

这个代码可以直接复制使用

HTML代码如下:

<el-upload
     class="avatar-uploader"
     action=""    //上传地址
     v-bind:data="{ FoldPath: '上传目录', SecretKey: '安全验证' }" //无需修改
     v-bind:on-progress="uploadVideoProcess"
     v-bind:on-success="handleVideoSuccess"
     v-bind:before-upload="beforeUploadVideo"
     v-bind:show-file-list="false"
     :headers="headers"   //头部携带的token
     >
     <video
     v-if="videoForm.showVideoPath != '' && !videoFlag"
     v-bind:src="videoForm.showVideoPath"   //上传后回显的地方
     class="avatar video-avatar"
     controls="controls">
     您的浏览器不支持视频播放
      </video>
     <i v-else-if="videoForm.showVideoPath == '' && !videoFlag" //i标签是上传前的那个+上传后隐藏
     class="el-icon-plus avatar-uploader-icon"
     ></i>
     <el-progress v-if="videoFlag == true" type="circle"
     v-bind:percentage="videoUploadPercent"
     style="margin-top: 7px"></el-progress>
 </el-upload>

JS如下:

 //上传前回调
    beforeUploadVideo(file) {
      var fileSize = file.size / 1024 / 1024 < 50;   //控制大小  修改50的值即可
      if (
        [
          "video/mp4",
          "video/ogg",
          "video/flv",
          "video/avi",
          "video/wmv",
          "video/rmvb",
          "video/mov",
        ].indexOf(file.type) == -1     //控制格式
      ) {
        layer.msg("请上传正确的视频格式");
        return false;
      }
      if (!fileSize) {
        layer.msg("视频大小不能超过50MB");
        return false;
      }
      this.isShowUploadVideo = false;
    },
    //进度条
    uploadVideoProcess(event, file, fileList) {    //注意在data中添加对应的变量名
      this.videoFlag = true;  
      this.videoUploadPercent = file.percentage.toFixed(0) * 1;
    },
    //上传成功回调
    handleVideoSuccess(res, file) {
      this.isShowUploadVideo = true;
      this.videoFlag = false;
      this.videoUploadPercent = 0;

      console.log(res);
      //后台上传数据
      if (res.success == true) {  
        this.videoForm.showVideoPath = res.data.url;    //上传成功后端返回视频地址 回显
      } else {
        this.$message.error("上传失败!");
      }
    },

data中至少需要:

      videoFlag: false,
      //是否显示进度条
      videoUploadPercent: "",
      //进度条的进度,
      isShowUploadVideo: false,
      //显示上传按钮
      videoForm: {
        showVideoPath: "",  //回显的变量
      },

style:

.avatar-uploader-icon {
  border: 1px dashed #d9d9d9 !important;
}
.avatar-uploader .el-upload {
  border: 1px dashed #d9d9d9 !important;
  border-radius: 6px !important;
  position: relative !important;
  overflow: hidden !important;
}
.avatar-uploader .el-upload:hover {
  border: 1px dashed #d9d9d9 !important;
  border-color: #409eff;
}
.avatar-uploader-icon {
  font-size: 28px;
  color: #8c939d;
  width: 300px;
  height: 178px;
  line-height: 178px;
  text-align: center;
}
.avatar {
  width: 300px;
  height: 178px;
  display: block;
}

这样就可以实现一个最基本的视频上传了。效果如下:

 一起加油!未来可期。
