歌曲地址解析器 yosong

项目开源地址:音乐消除国界,下载废除权限:歌曲地址解析器 yosong 感谢作者

那么,现在情况是这个样子的,我又想下歌了。在很久很久以前,百度音乐上的歌曲存有 128kbps、192kbps、320kbps 三种品质的,当时注册一个普通帐号就可以下载任意品质,在懒惰魔的诱惑下,我写了个叫 biabiamiamia 的程序,帮我下载指定歌手的全部歌曲
,那时候,喜欢的歌手基本都被拖到硬盘上了。最近,广播里放了几首新人的歌,邓紫棋版的“黑腹美”很是喜欢,好吧,把 biabiamiamia 翻出来看下还能跑不?我勒个去,完全用不起啊。是当个丑男还是当个懒人呢?好吧,一懒到底,必须得有个程序帮我批量下载。
现在的百度音乐存有普通品质(128kbps)、高品质(192kbps)、超高品质(320kbps)、无损品质(flac 800+kbps)四种,其中,320 的需要 VIP 帐号才能下载,而 flac 的甚至需要白金 VIP 才能下载,程序必须首先解决帐号权限的问题;另外,之前监管不那么严格的时候,百度音乐提供大量歌曲免费供大家下载,后来百度开始收费,那么相应百度自己需要先购买这些歌曲的版权,对于百度买了版权的歌曲,它当然可以通过收费会员机制盈利,但,未购买版权的歌曲,即便服务器上有现成的资源,也不得提供给会员下载,所以,程序还得解决这类因百度自身版权而无法下载的问题,比如,王菲-《醇经典》-誓言(http://music.baidu.com/song/s/75053f8340854da16d5 )。
耽误了我一周乒乓球时光,总算找到了可靠方法,剩下的就是编码实现 yosong,除了上述两个功能外,顺带实现了其它几项,基本上,现在的 yosong 具备了以下能力:
0)绕开白金收费会员才能下载无损品质歌曲的限制;
1)绕开百度自身版权问题歌曲而无法下载的限制(即便白金收费会员从官方渠道也无该功能);
2)绕开非大陆之外区域无法下载的限制(即便白金收费会员从官方渠道也无该功能);
3)一键式全站歌曲下载(即便白金收费会员从官方渠道也无该功能);
4)绕开高频访问出现验证码的限制。
虽然我用了"下载"这个词,但 yosong 并不会为你下载任何歌曲,严格地说,它是个百度歌曲最终下载地址解析工具,就我而言,我会先让 yosong 帮我解析出指定歌手的所有歌曲的 320 码率最终下载地址,然后以专辑为单位丢给迅雷帮我批量下载。
##源码安装
####‘linux’ 0)唯一依赖 libcurl,请自行安装;
1)代码采用 C++11 编写,gcc 版本不低于 4.7.1。
2)命令行下运行:
$ cd yosong/build/
$ cmake .
$ make && sudo make install
####‘osX’ 先将 build/CMakeLists.txt 中的
TARGET_LINK_LIBRARIES(yosong curl pthread)
替换成
TARGET_LINK_LIBRARIES(yosong curl pthread iconv)
其他同 linux 构建方法。
##命令行选项
yosong 是一个命令行程序,要用好它,你得先了解几个命令行选项的常识:
0)--option 'argc',其中,--option 称之为命令行选项,argc 为命令行参数;
1)某些命令行参数中可能含有对 shell 有特殊含义的字符(如,后台运行的 &、用于分割符的空格),为避免 shell 误解,通常,应该用英文单引号包裹命令行参数。如,--user 'yangyangwithgnu';
2)某些命令行选项可以有多个参数,通常,每个参数单独用英文单引号包裹,参数间用空格分割。如,--album '八度空间' '范特西' '我很忙';
yosong 典型的用法:
yosong --user 'yangyangwithgnu' --password 'abcd1234' --artist '伍佰'
这样,yosong 就会帮你把歌手伍佰的所有歌曲的 320 码率下载地址解析出来,一是输出在屏幕上、一是保存至 ~/伍佰@HHMMSS.txt 中。
具体而言,yosong 提供了如下命令行选项。
--help
显示帮助信息。该选项优先级最高,出现该选项时忽略其他所有选项。
可选。
--version
显示当前版本信息。该选项优先级仅次 --help
可选。
--user
指定百度帐号。普通免费帐号即可,无需白金付费会员帐号。
必填。
单参数。
无默认值。
--password
指定百度帐号密码。
必填。
单参数。
无默认值。
--artist
指定歌手名。
必填。
单参数。
无默认值。
--album
指定专辑名。该专辑必须归属 --artist 指定歌手的,否则无法下载。若未指定该选项则默认下载 --artist 指定的歌手的所有专辑、所有歌曲。若有多张专辑,请空格隔开,如,--album '八度空间' '范特西' '我很忙'。
可选。
多参数。
无默认值。
--quality
指定歌曲品质。百毒音乐上的歌曲有四种品质:标准品质(128kbps)、高品质(192kbps)、超高品质(320kbps)、无损品质(800+kbps),yosong 依次有四种参数与之对应:128、192、320、flac。如果指定品质不存在,那么依次找 320、192、128、flac 等存在的品质,找到即下。
必填。
单参数。
默认值,320。
--ignore-size-lower
有些歌曲尺寸太小相应音质就不高,若想忽略小尺寸的歌曲,可以通过该选项指定一个以 MB 为单位的尺寸下限,凡低于该尺寸的歌曲均不下载。注意,0)该选项的参数可以指定小数;1)指定时不用带单位,如,--ignore-size-lower 6 而非 --ignore-size-lower 6M;2)如果不在乎歌曲尺寸可以将该选项指定为 0。
必填。
单参数。
默认值,6。
--path
指定歌曲最终下载地址保存路径,文件命名规则:artistname@hhmmss.txt
必填。
单参数。
默认值,~/
##FQA
Q0:yosong 可以解析哪些歌手的歌曲?
A0http://music.baidu.com/artist
Q1:为何我昨天解析出的最终下载地址,今天下载全部失败呢?
A1:最终下载地址是有有效期的,要下载时才解析,不要先解析一大堆等多久才下载,很可能过期滴。
Q2:yosong 为何不集成下载工具?
A2:我是个受尽 K.I.S.S. 摧残的人儿,术有专攻,让其他第三方专业下载工具去执行具体下载任务吧。当然,我也是个有爱的人儿,帮你准备了
bool Song::download (const string& path, const string& quality, const unsigned timeout);
成员函数,它内部集成 aria2c,适当调整下 main.cpp 中的逻辑即可集成下载。我倒是建议直接用迅雷,以专辑为单位把整个专辑的下载地址拷贝下来,迅雷自动除去非 URL 文本,批量下载,并且还能正确给文件命名。
Q3:为何有类似“咖哩鱼蛋(1.1MB too small)”红色报错信息?
A3:有些歌曲尺寸太小相应音质就不高,对于您这样有品味的人,宁可不下载也不要被这些低质声音污染耳朵,所以,你可以通过该选项指定一个以 MB 为单位的尺寸下限,告诉 yosong 忽略小于该尺寸的歌曲。如果你是个接受度很广的人,可以将 --ignore-size-lower 设置为 0。
Q4:为何默认品质是 320 而不是无损的 flac?
A4:尼玛,劳资的车载音响不支持 flac 格式 (ง •̀_•́)ง
Q5:为何迅雷下载回来的歌曲出现类似 96892368400320.mp3 这样的文件名?
A5:yosong 解析出来的最终下载地址类似 http://yinyueshiting.baidu.com/data2/music/51503996/96892368400320.mp3?xcode=0518d0d4beb3be2fea45adb97777a278d990c3a07c5eb44d ,通常来说,下载工具会向资源提供服务端查询文件名,然后再下载,迅雷在这方面做得不错,但如果你向单个资源服务器同时发起大量并行查询,其中某几个可能查询失败,所以就出现迅雷按 URL 中的信息给文件命名的情况。要规避这种情况,你可以减少并行下载任务数量(4 个为宜),或者,对已经下载的文件,右键查看音频属性,那儿会有正确的歌曲名,如下图:

(音频属性中提取真实文件名)
Q6:周杰伦的歌明显不全嘛?
A6:对于百度未收录的歌曲资源,yosong 无能为力。
Q7:yosong 要求输入百毒帐号,安不安全?
A7:不安全。我可能把持不住用你的帐号干各种邪恶、抑郁以及不纯洁的事。为了您一身的英明,建议你注册个小号,明白我的意思了么,亲爱的。
Q8:yosong 是否具备“一键”解析百毒音乐全站歌曲的能力?
A8:哼哼哼,好像、或许、应该、我觉得,是具备的。你知道,只需指定歌手名,yosong 能解析该歌手的所有专辑的所有歌曲,同时,yosong 又能遍历出所有歌手,所以,只需增加八行代码即可,具体是 ...,等下,我接个电话先,010-65232656 打来的 ...
Q9:我指定下载 flac 这种无损品质,为何 yosong 下载回来的是 mp3 格式呢?
A9:百毒音乐上的歌曲含有标准品质(128kbps)、高品质(192kbps)、超高品质(320kbps)、无损品质(800+kbps)等四种品质,前三者为 mp3 格式、最后一种为 flac 格式。大部分歌曲四种品质都有,少部分歌曲缺失某类品质,如果指定品质不存在,那么 yosong 依次查找 320、192、128、flac 等存在的品质,找到即下,所以,如果你指定的是 flac 而下载回来的是 mp3,那肯定是该歌曲缺失 flac 品质。至于说,在指定品质不存在时,查找优先级为何把 flac 排在最后,前面说过了,那是因为劳资的车载音响不支持 flac 格式,基本上,我只下载 320 品质的 mp3,如果某歌曲没有 320 的,我希望下载 192 的,而不是“自作聪明”下 flac 的。
Q10:yosong 最小只能以专辑为单位下载,如果我只想下载单首歌曲,咋办啊?
A10:请在门外帮我把门关上。
Q11:非正常退出 yosong 有无危害?
A11:yosong 通过某些机制绕开百度限制,其中涉及把歌曲加入收藏,收藏夹有收藏歌曲数量的限制(8K),虽然 yosong 会自动清理由它加入收藏的歌曲,但,当非正常退出时,清理这步可能未执行,所以,建议定期到 http://yinyueyun.baidu.com/ 手工清理收藏夹,否则,yosong 无法正常运行。
##接下来你可以
yosong 不是终点,而是你的起点,基于它你可以:
0)调用 Song::download() 集成 aria2c 下载工具;
1)创建 GUI 版本,为害怕 CLI 的亲们带去曙光;
2)创建网站版本,yosong 在幕后,提供歌曲下载地址解析,类似硕鼠网;
3)移植 windows 版本。
##最后的一定是最不重要的

Steve Jobs at 44, By Michael Krantz, 1999

Differences and Similarities Between Apple and Pixar Apple turns out many products--a dozen a year; if you count all the minor ones, probably a hundred. Pixar is striving to turn out one a year. But the converse of that is that Pixar's products will still be used fifty years from now, whereas I don't think you'll be using any product Apple brings to market this year fifty years from now. Pixar is making art for the ages. Kids will be watching Toy Story in the future. And Apple is much more of a constant race to continually improve things and stay ahead of the competition.  His Role At Pixar At Pixar my job is to help build the studio and recruit people and help create a situation where they can do the best work of their lives. And to some degree it's the same at Apple. But at Pixar, I don't direct the movies, whereas at Apple probably, if I had to pick a role out of a film production, I'd be the director. So it...

《Becoming Steve Jobs》Chapter 12 Two Decisions

Jim Collins, the bestselling author of the management classics Built to Last: Successful Habits of Visionary Companies and Good to Great: Why Some Companies Make the Leap … and Others Don’t, has a wonderful phrase to describe an essential characteristic of great leaders: deep restlessness. Collins applies the phrase to Steve, one of the two great leaders who inspire him the most (the other is Winston Churchill, the great English politician who was prime minister during most of World War II, from 1940 to 1945, and again from 1951 to 1955). Collins believes this restlessness is far more important and powerful than simple ambition or raw intelligence. It is the foundation of resilience, and self-motivation. It is fueled by curiosity, the ache to build something meaningful, and a sense of purpose to make the most of one’s entire life. 自己何其有幸,在不到30的年纪,就能感受到乔布斯的心境 “The things he was trying to do,” says Collins, “were always hard. Sometimes those things beat him up. But the response to fighti...

Foobar2000 组件安装教程

 原作者 博客地址   汉化作者 Asion博客   关于foobar 2000的一些资源 前言 foobar2000 由于其软件架构特点以及开放的姿态,使得第三方很容易开发组件(component)来拓展它的功能。由于在官网下载的默认安装文件只带了少量几个默认的组件,满足不了使用的需求,例如:默认不带 ape,tta,tak 等音频文件格式的解码器,很多无损压缩格式音乐没法播放。所以自己下载安装组件是必备的基本技能。 foobar2000 的中文汉化版(Asion 汉化)为了方便使用,集成了无损压缩文件解码器以及一些其它有用的插件,安装时选上即可,不喜欢折腾的建议使用汉化版。 这里组件指的是 foobar2000 标准组件(*.dll 文件),而非 vst 插件等其它插件,姑且把组件分为两类: 官方组件: 英文版安装包自带,安装时可选择; 第三方组件:非官方自带的组件 除了 foo_input_std.dll 和 foo_ui_std.dll 这两个组件是必须的外,其它的所有组件都 非必需 的,可以随需要增删。第三方组件可以去 官网 、 官方论坛 或者 官方 wiki 去找,也可以去贴吧等地逛逛。 下载 还是要强调一下,这里说的是 foobar2000 component ,不是中文网上通常说的 vst 插件。 下载好的组件包一般是 xxx.zip 或 xxx.fb2k-component 格式的文件,也有用 7z 打包的。前两种都是 zip 压缩(只要把 fb2k-component 改成 zip 文件就变成了 zip: 包)。标准状况下压缩包里的内容结构应该是 xxx.zip yyy.dll README.txt (可能没有) LICENCE.txt (可能没有) (其它杂七杂八) 除少数外一般只有一个 xxx.dll 文件.一定要注意压缩包结构不能是: xxx.zip yy folder (文件夹) zzz.dll … 否则要解压缩,提取那个 dll 文件。 安装 方法一(推荐) 打开 foobar2000 的菜单 文件 > 首选项(file >preferences) 的 组件(components...

《Becoming Steve Jobs》Chapter 15 The Whole Widget

What the world did see was an effective and visionary leader at the height of his powers. These were complicated years for Apple, but Steve handled almost every challenge in exactly the manner he wanted. He had fallen into leadership at such a young age, but he was comfortable in that role now, and justifiably sure of his capacity to guide Apple’s tens of thousands of employees to the goals he set for them. During these years, he would ensure the company’s continued success in personal computers by engineering a deft switch to a new kind of microprocessor; ruthlessly and successfully managing some major transitions in his executive team; and optimizing and building upon the efficiency and ambition of the company’s product development “treadmill,” as Tim Cook describes it. This is also when he delivered what is likely to be remembered as the most notable product of his life, the iPhone, and then improved even that by pivoting once again into a strategy he personally had not wanted to pu...

产品随想 | 陪读《Make Something Wonderful:Steve Jobs in his own words》1976-1996

  There’s lots of ways to be, as a person. And some people express their deep appreciation in different ways. But one of the ways that I believe people express their appreciation to the rest of humanity is to make something wonderful and put it out there. And you never meet the people. You never shake their hands. You never hear their story or tell yours. But somehow, in the act of making something with a great deal of care and love, something’s transmitted there. And it’s a way of expressing to the rest of our species our deep appreciation. So we need to be true to who we are and remember what’s really important to us. ──Steve, 2007 Introduction by Laurene Powell Jobs Much of what’s in these pages reflects guiding themes of Steve’s life: his sense of the worlds that would emerge from marrying the arts and technology; his unbelievable rigor, which he imposed first and most strenuously on himself; his tenacity in pursuit of assembling and leading great teams; and perhaps, above all,...

巴菲特致股东信-1976年

 笔记: 为什么选择轻资产行业:当竞争疯狂时,不会强迫加入降价大战 最终选择了费雪的思想,选择能理解的优秀企业,以合理的价格买入并长期拥有 翻译: 雪球:https://xueqiu.com/6217262310/131440258 备份:https://archive.ph/XLK0S 原文: To the Stockholders of Berkshire Hathaway Inc, After two dismal years, operating results in 1976 improved significantly. Last year we said the degree of progress in insurance underwriting would determine whether our gain in earnings would be "moderate" or "major." As it turned out, earnings exceeded even the high end of our expectations. In large part, this was due to the outstanding efforts of Phil Liesche's managerial group at National Indemnity Company. In dollar terms, operating earnings came to $16,073,000, or $16.47 per share. While this is a record figure, we consider return on shareholders' equity to be a much more significant yardstick of economic performance. Here our result was 17.3%, moderately above our long-term average and even further above the average o...

《Becoming Steve Jobs》Chapter 11 Do Your Level Best

As a mass-market consumer electronics device, the iPod would eventually be sold, of course, all the usual places: Best Buy, Circuit City, big-box department stores, and even the computer retailers like CompUSA. Steve disdained all these outlets. His obsession with his products continued well after they’d been manufactured. The tacky, low-margin hustle of these chains ran completely against the minimalist aesthetic of his products and the clean exuberance of his marketing. There was only one place where he really enjoyed seeing his products sold to the public: his own Apple stores, which had debuted four months ahead of the iPod. 觉得那些喧嚣、嘈杂的零售渠道,配不上自己极美的产品 Going back as far as the debut of the Mac, Steve had always groused about the way Apple computers were sold in its resellers’ stores. The way his computers were displayed and sold represented the very worst of what could go wrong when things weren’t done his way. The salespeople, always interested in quick turnover, seemed to make litt...

《Becoming Steve Jobs》Chapter 16 Blind Spots, Grudges, and Sharp Elbows

Steve could be pretty thin-skinned when someone prominent criticized the aesthetics of his products. He took great umbrage that Neil would, as Steve put it, “pop off in public like that without coming to talk to us about his technical concerns first.” From that point on he had rebuffed all of Neil’s attempts to smoke the peace pipe. 有趣 He had blind spots, grating behavioral habits, and a tendency to give in to emotional impulse that persisted his entire life. These characteristics are often used to make the case that Steve was an “asshole” or a “jerk,” or perhaps simply “binary”—that odd adjective often used to convey the sense that he was half asshole/half genius from birth to death. These aren’t useful, interesting, or enlightening descriptions. What’s more illuminating is to take a look at the specific ways in which Steve failed to do an effective job of tempering some of his weaknesses and antisocial traits, and to consider how, when, and why some of them continued to flare up even...
