uniapp 开发微信小程序

格式化当前日期

 
async getDate() {
        var t = new Date(),
          e = (t.getFullYear(), t.getMonth() + 1),
          o = t.getDate(),
          a = t.getHours(),
          n = t.getMinutes(),
          i = (t.getSeconds(), e + "月" + o + "日"),
          s = [a, n].map(this.formatNumber).join(":");
         console.log(i), console.log(s), 
            this.setData({
          date: i,
          time: s
        });
},
    

用时间来拼凑路径

                var path = imgs[i].url;
                var extension = path.substring(path.lastIndexOf('.') + 1)
                var random = String(Math.random()*100000).split('.')[0]
                var now = new Date()
                var year = now.getFullYear()
                var month = (now.getMonth() + 1) < 10?'0'+(now.getMonth() + 1):(now.getMonth() + 1)
				var day = now.getDate() < 10?'0'+now.getDate():now.getDate()
				var hours = now.getHours() < 10?'0'+now.getHours():now.getHours()
				var minutes = now.getMinutes() < 10?'0'+now.getMinutes():now.getMinutes()
				var seconds = now.getSeconds() < 10?'0'+now.getSeconds():now.getSeconds()
				
				var cloudPath = 								'wall'+'/'+year+'/'+month+'/'+day+'/'+hours+minutes+seconds+'_'+random+'.'+extension

格式化数字为最低报错两位数

 formatNumber: function(t) {
        return (t = t.toString())[1] ? t : "0" + t;
},

uniapp 上传图片到uniCloud 云存储

利用uview写的css部分(具体参数查看uview)

<u-upload
        ref="uUpload"
        action=""
        max-count="100"
        :file-list="''"
        :auto-upload="false"
        :uploadText="cover.mode == 0 ? '上传壁纸' : '上传图片'"
        :width="cover.mode == 0 ? 203 : 203"
        :height="cover.mode == 0 ? 325 : 203"
        :maxSize="10 * 1024 * 1024"
        :show-progress="false"
        :size-type="['original']"
        :source-type="['album']"
        :multiple="true"
        del-icon="close"
        del-bg-color="#ff7c7c"
        del-color="#FFFFFF"
        :limitType="['png', 'jpg', 'jpeg']"
></u-upload>

JavaScript部分

async submit() {
    var that = this;
    var imgs = that.$refs.uUpload.lists;
    await uniCloud.uploadFile({
        filePath: path,    	  // 文件路径
        cloudPath: cloudPath  // 存入云存储的路径
    }).then(async res => {
        console.log(res,'resUploadFile')
        await uniCloud.getTempFileURL({    // 根据返回的id 来获取云存储上的路径
            fileList: [res.fileID]
        }).then(res => {
            console.log(res,'getTempFileURL')
            if(res.fileList.length > 0){
                imgPaths.push(res.fileList[0].tempFileURL)
            }else{
                that.$u.toast("图片上传失败");
                return;
            }
        });
    })
}
