XML get web site video

We all know that watching free movies can not give you some ads, quoting other Web site video to their site is OK, but ads can not be less, how to advertise, look down!

The usual way to get the player address is through:

You can also click the right button to see the source code, and find its address.

That is

1:file_get_contents/curl-page HTML
2: Regular Analysis video address

Disadvantages:
1: Slow, HTML page larger, there is a lot of information is "impurity" information
2: If the page is revised, the collection rules may fail.

So, we don't use that method, using the following

Using the Potato API to get XML information
1:xml is pure data, content is small, get fast
2: Pure data, such as title, length and so on, these will not change. Hard to fail.




At present, the major websites have their own open interface, application programing interface, application interface

Using the website's API, you can search for information

How to get the API interface:

Baidu Search Potato API, register application, get two important values
