前面我发了一篇文章,向大家推荐了一个听歌软件:Listen(原文链接),我一般是在Edge浏览器里安装插件使用的,但是由于我是用的iPhone手机,然后Listen的源码我又一直编译不过去(吐槽下ReactNative)所以想自己撸一个听歌软件自己用.
技术选型本人原本是做ios开发的,但是奈何objective-C比较难用,swift又一言难尽,swiftUI坑又比较多.在加上最近flutter比较火,而我之前也在demo上试了写了一下,感觉还不错,所以就打算使用flutter来写app了.
而且flutter还是跨平台的,还可以把android windows的一起给搞定了,嘿嘿~ 美滋滋
api接口巧妇难为无米之炊,没有接口也没法进行下去啊. 我第一时间想到的是抓Listen1的包. 但是咪咕渠道的有个sid字段的值不知道是什么规则生成的,每次都不一样.导致我咪咕渠道的api迟迟搞不定.
不过我在github上找到了其它可用的api(链接地址),谢谢这位大哥了嘿嘿.

哎,我为啥要在头条上发这种东西呢?这种东西真的有人看吗?
不管了,发几张成品图:
顺便搞了个mac版的,上班好好用 嘿嘿
虽然界面比较简陋,但是听歌的搞这么花里胡哨的干啥呢,是吧?
