Tips:
1, when the request interface, if the short URL to generate micro-letters, found the tail of the original URL parameter is missing how to do? Urlencode do need to deal with the original link, and then go to generate.
2, the long URL request interface must be to http (s): // at the beginning, as this may cause the build to fail.
3, interface request frequency recommended not too fast, normal 1 / s, completely sufficient.
common problem:
1, after long URLs into why the argument is lost?
A: Because not do urlencode process, resulting in some special characters not recognized. The encoder then needs to request interface url.
2, request interface Why did not return a result?
A: Sometimes there is a delay data interface to return, it will lead to time-out did not return. Or because the original link was closed.
3, url generate a short URL is valid for how long? There is no limit visits?
A: Share short URL generated interface is valid, the official version of the interface to generate short URLs are permanently valid.
4, there is no short URL access restrictions?
A: This interface is based on the official website interfaces developed, no visits limited, and ease of use.
