Baidu MP3 music API interface and Application

Here is an application about the Baidu MP3 music API. I wrote an application about this Baidu interface, which provides a small part of the search function, using it for MP3 search is still interesting. But the provided interface method still has some defects. However, it is quite interesting to use it on Weibo. Sina Weibo does not provide this search information interface when it does not cooperate with the official team. It can only be used by partners. Baidu has powerful search capabilities, but data is not open to individuals. Therefore, this small interface can only be used.

 

As the author mentioned above, it is impossible to search for a song that requires both the song name and the song name. The problem is that searching is inconvenient.

Another saying is that inputting these two keywords is helpful for positioning, But you need to remember the singer and song name, and the return time is relatively fast.

 

However, temporary use is also possible.

 

Http://box.zhangmen.baidu.com/X? OP = 12 & COUNT = 1 & Title = about winter $ Qi Qin $

 

 

Using this interface, we need to modify it first.

Http://box.zhangmen.baidu.com/X? OP = 12 & COUNT = 1 & Title = songname $ songauthor $

 

Modify two keywords to facilitate replacement.

Use a string to separate the strings, and use the "#" symbol to mark the strings.

In this way, you can replace the desired link address when searching.

VaR infoarray: array = info. split ("#"); </P> <p> var newstr: String = searapiurl. replace ("songname", infoarray [0]); <br/> newstr = newstr. replace ("songauthor", infoarray [1]); </P> <p>

 

Remove unnecessary spaces when replacing them, and you can enter them at will.

// Remove the blank <br/> private function replacspace (STR: string): String <br/>{< br/> return STR = Str. replace (/s) */GI, ""); </P> <p>}

 

 

Remotely calling this interface will return a small number of Song links. At this time, we will splice the songs for search. Because we only need MP3 files, therefore, WMA and RM are not what we need. Therefore, we need to make a handsome selection when searching for the returned results. After selection, we need to bind it to an array. We want to get the lyrics, at the same time, the practice is to refer to the practice mentioned in the previous article to splice the LRC address. The LRC address may be blank, so you can add a condition to make the selection.

// Crop the MP3 address <br/> private function getsongaddress (URL: String, songname: string): String <br/>{< br/> var end: Int = URL. lastindexof ("/", URL. length-1); <br/> return URL. substring (0, end + 1) + songname; <br/>}</P> <p> // returns the LRC address <br/> private function getlrc (URL: string): String <br/>{< br/> return lrcurl + int (INT (URL)/100 ). tostring () + "/" + URL + ". LRC "; <br/>}< br/>

 

 

An XML file is returned by calling this interface:

For example:

<? XML version = "1.0" encoding = "gb2312"?> <Br/>-<result> <br/> <count> 5 </count> <br/>-<URL> <br/> <encode> disable </encode> <br/> <decode> response? Xcode = bfdfd728537234893c350b4e1ff22833 </decode> <br/> <type> 1 </type> <br/> <lrcid> 14706 </lrcid> <br/> </URL> <br/>-<URL> <br/> <encode> http://individual.utoronto.ca/xmc84/fpOslpp ~ Py-aokezpzy1_limit </encode> <br/> <decode> maybeinwinterlimit </decode> <br/> <type> 1 </type> <br/> <lrcid> 14706 </lrcid> <br/> </URL> <br/>-<URL> <br/> <encode> http://vietnamese.cri.cn/mmsource/audio/2004/07/27/lZOsqZqwmKGVoaGbn583.rm </encode> <br/> <decode> dayuezaidongji. rm </decode> <br/> <type> 2 </type> <br/> <lrcid> 14706 </lrcid> <br/> </URL> <br/ >-<URL> <br/> <encode> scheme </encode> <br/> <decode> about winter solstice </decode> <br/> <type> 1 </Type> <br/> <lrcid> 14706 </lrcid> <br/> </URL> <br/>-<URL> <br/> <encode> HTTP: // 120.35.4.23/data/MP3/logs </encode> <br/> <decode> encoding </decode> <br/> <type> 1 </type> <br/> <lrcid> 14706 </lrcid> <br/> </URL> <br/>-<P2P> <br/> <pash> 5babc209cd096f0a3529a3dc8f66754bc58d0e29 </HASH> <br/> </P2P> <br/> </result>

 

 

The XML operation returns the desired node:

 

Encode: Song address path

Decode: song name

Type: Type

Lrcid: lrc

Encode and

Data on the decode node is spliced. For details, refer to the preceding section.

After editing, you can perform this operation to enrich the data used in the search.

After being integrated into the Weibo client, you can share songs and view the lyrics.
