uni-app是一个使用 Vue.js 开发所有前端应用的框架,开发者编写一套代码,可编译到iOS、Android、H5、以及各种小程序(微信/阿里/百度/头条/QQ)等多个平台。
最近公司开发一个项目时用到了这个框架,初次接触,难免遇到不少坑,不过这个框架还是很不错的!建议大家可以用一用。废话不多说,切入正题,如何用uniapp开发能正常播放的CC视频,因为最近项目中有这个需求功能,开始在网上找了半天资料,发觉都不好用无法达到正常播放的需求。后来咨询了CC客服,他们回复说没有支持VUE框架的接口,后来了解到有个MobileAPI的接口,没办法项目总要做,该解决的问题终归得解决!后来仔细看了开发文档,几经周折终于调试通了!下面就简单说说遇到的一些难点吧!
首先,需要获取到他们的MobileAPI的接口文档,文档描述的很简单,请求参数也很简单,难就难在:需要和API系统进⾏行行 HTTP 通信时,需要将原始的 Query String 转换为和请求时刻相关的 Hashed Query String 后再通过 GET ⽅方法请求 Spark API。当时就是卡在这一步上浪费了小半天时间。
附上官方Mobile API接口文档:链接: https://pan.baidu.com/s/1su67eIBqQhz3nluQubZXzw 提取码: n572
这里的userid和videoid都可以动态传递,也可以写死。
请求数据的方法,需要用到一系列md5函数:
最后附上全部代码:
