这段代码是一个工具函数集合，包含了以下几个函数：

  1. parseTime：将时间转换为指定格式的字符串。

  2. formatTime：将时间转换为人性化的表示，如“刚刚”、“1小时前”、“1天前”等。

  3. param2Obj：将 URL 中的参数解析为对象。

  4. randomString：生成指定长度的随机字符串。

  5. dataUpload：封装上传数据的格式，包括数据本身、时间、随机数等。

  6. dataUpload1：简单地将输入的数据返回。

这些函数都是为了方便开发者进行常见操作而设计的，可以在各种场景中使用。

你可以举个例子演示如何使用么？

当然可以。以下是一些使用这些函数的示例：

  1. 使用 parseTime 函数将时间转换为指定格式的字符串：
import { parseTime } from './utils'

const time = new Date()
const timeStr = parseTime(time, '{y}-{m}-{d} {h}:{i}:{s}')
console.log(timeStr) // 输出类似于 "2021-04-22 13:30:00" 的字符串
  1. 使用 formatTime 函数将时间转换为人性化的表示：
import { formatTime } from './utils'

const time = new Date().getTime() - 3600 * 1000
const timeStr = formatTime(time)
console.log(timeStr) // 输出类似于 "1小时前" 的字符串
  1. 使用 param2Obj 函数将 URL 中的参数解析为对象：
import { param2Obj } from './utils'

const url = 'http://example.com/?name=John&age=30'
const params = param2Obj(url)
console.log(params) // 输出 { name: "John", age: "30" }
  1. 使用 randomString 函数生成指定长度的随机字符串：
import { randomString } from './utils'

const random = randomString(10)
console.log(random) // 输出类似于 "8H4PZ9X3E2" 的字符串
  1. 使用 dataUpload 函数将数据按照指定格式上传：
import { dataUpload } from './utils'

const resourceName = 'user'
const data = { name: 'John', age: 30 }
const paramUrl = 'http://example.com/api/user'
const params = { token: 'abcdefg123456' }
const uploadData = dataUpload(resourceName, data, paramUrl, params)
console.log(uploadData) // 输出一个符合指定格式的上传数据对象
  1. 使用 dataUpload1 函数简单地将输入的数据返回：
import { dataUpload1 } from './utils'

const data = { name: 'John', age: 30 }
const result = dataUpload1(data)
console.log(result) // 输出原始的数据对象
