Precautions:
① When calling api interface simply "http://www.baidu.com" replaced the need to shorten the long URL.
② interface supports url parameters, when the & symbol appears in the url, use 26% instead of (or use the url encoding format), or parameters may be lost.
When ③ fill url, must be based on http (s): // at the beginning, it may cause a short URL to give birth can not access the original site.
Several url.cn short URL api interfaces ④ mentioned above, the tests are relatively stable, it felt good to remember collection, to avoid loss.
common problem:
① long link translation parameters why the end is lost?
A: Because the url contains special characters, you need to use UTF8 encoding format, the url coding!
② interface does not return a result, what is the situation?
A: Sometimes the interface returns the data will be delayed, the delay did not return will be prompted to generate a failure; or because the original link was closed.
Short URL generated is valid ③ how long? There is no limit visits?
A: The short URL is generated url permanent and effective, and there is no limit clicks, you can use any!
