Call method (take Sina t.cn short link api API as an example):

Demo of PHP call:

$url = 'http://www.baidu.com';$api_url =' http://qingmeidwz.cn/shorten.json?url_long=http://www.baidu.com';$short_url = file_get_contents ($api_url); echo $short_url

Demo of JAVA call:

Public static void main (String path []) throws Exception {URL u = new URL ("http://qingmeidwz.cn/shorten.json?url_long=http://www.baidu.com");InputStream in = u.openStream (); ByteArrayOutputStream out = new ByteArrayOutputStream (); try {byte buf [] = new byte [1024]; int read = 0X while (read = in .read (buf)) > 0) {out.write (buf, 0, read);}} finally {if (in! = null) {in .close () }} byte b [] = out.toByteArray (); System.out.println (new String (b, "utf-8"));}

Demo of Python call:

Import urllib, urllib2, syshost = 'http://qingmeidwz.cn/'path =' shorten.json?url_long='method = 'GET'querys =' url=http%3A%2F%2Fwww.baidu.com'bodys = {} url= host + path +'?'+ querysrequest = urllib2.Request (url) response = urllib2.urlopen (request) content = response.read () if (content): print (content)

Note:

When ① calls the api interface, simply replace "http://www.baidu.com"" with a long URL that needs to be shortened.

The ② interface supports the url parameter. When the & symbol appears in url, replace it with% 26, otherwise the parameter may be lost.

③ must start with http (s): / / when filling in url, otherwise the resulting short URL may not be able to access the original website.

④ above Wechat url.cn, Sina t.cn short URL api interface, after testing is very stable, feel good to remember to collect, so as not to lose.

Frequently asked questions:

① long link conversion, why is the parameter at the end lost?

Answer: because url contains special characters, you need to use UTF8 encoding format to encode url

The ② interface does not return a result. What happens?

A: sometimes there is a delay in the return of data from the API. If the delay is not returned, it will indicate that the generation failed, or because the original link is blocked.

How long is the validity period of the short URL generated by ③? Is there a limit on the number of visits?

A: the generated short URLs are permanent, and there is no limit on the number of clicks, so you can use them at will.

At this point, the study on "how php and python call short URLs to generate api interface" is over. I hope to be able to solve your doubts.
