小程序真机上传视频为啥那么慢,大点的视频上传不上去，是uploadFile的问题？

wx.chooseVideo({
	maxDuration: 60,
	compressed: false,
	success: function(res) {
		var tempFilePath = res.tempFilePath;
		wx.uploadFile({
			url: 'http://dfsfds',
			filePath: tempFilePath,
			name: 'file',
			formData: {
				'folder': 'test'
			},
			header: {
				'content-type': 'application/json',
				'Authorization': wx.getStorageSync('token')
			},
			success(res) {
				var data = JSON.parse(res.data);
				console.log(res.data)
				if(data.code==200){
				        that.setData({
					     load_video1: data.data, //素材图片
				        })
				}else{
					wx.showToast({
						title: data.msg,
						icon: "none"
					})
				}
			},
			fail(res){
				wx.showToast({
					title: res,
				        icon: "none"
				})
			}
		})			
	}
})
