Music API for MyFreeMP3 and MyFreeMP3(old)

Requirements:

//@grant GM_xmlhttpRequest
//@connect api.liumingye.cn
//@connect api2.liumingye.cn

Usage: This method will request new or old api and provides a standardized callback argument object. Recommended.

Mfapi.search({
type: 'YQD', // Search songs in "M" then use "YQM", search in "B" then use "YQB", search in "D" then use "YQD", etc; Default: "YQD"
text: 'your search params', // Song name, artist names, etc
page: 1, // Default: 1
callback: function(json) { console.log(json); },
onerror: function(err) { console.log(err); }, // Default: function() {}
api: 'auto' // Which api to use, 'new','old' or 'auto' for automatically choose, Default: 'auto'
}, 3);
// The second argument is retry count,  meaning how many retries we'll take before onerror got called.
// This number will be doubled if your api === 'auto' because we have to try both new and old apis if one of them is unavailable.
// Default: 3

You can specific different type, text, page, callback, and onerror for different apis by providing an object. For example, if you want to search text 'Song A' while requesting 'new' api but search 'Song B' while requesting 'old' api, you can use code like this:

Mfapi.search({
type: 'YQD', // Search songs in "M" then use "YQM", search in "B" then use "YQB", search in "D" then use "YQD", etc; Default: "YQD"
text: {
new: 'Song A', // Search 'Song A' while requesting new api
old: 'Song B'  // Search 'Song B' while requesting old api
},
page: 1, // Default: 1
callback: function(json) { console.log(json); },
onerror: function(err) { console.log(err); }, // Default: function() {}
api: 'auto' // Which api to use, 'new','old' or 'auto' for automatically choose, Default: 'auto'
}, 3);

This may be useful when api is 'auto'.

or you can request old or new api directly to access raw api return value.

Mfapi.new.search({ type, text, page, callback, onerror });

Mfapi.old.search({ type, text, page, callback, onerror });

The apis' token encoders are also provided as Mfapi.new.encode and Mfapi.old.encode, and there's also Mfapi.new.link and Mfapi.old.link methods which accepts a song object and a quality number and returns its download url.

Try it out yourself and look into the callback values!
