下面是一米的样本:

http://www.asfradio.com/device.asp?u=username&p=password&s=east

B. 目前的检查 我在守则中使用:

if (data.endsWith(".asf") || (0 < data.indexOf(".asf")))

因此,在这种情况下,我的检查失败,是因为有的放大机,但随后是无线电台,使我的逻辑错误,因为这种联系不是像样的。

如果发现“......asf”和“f”之后的下一个特性不是一封信,那么我想要的是定期表达。

希望它能发挥作用......

检查档案延期的最简单办法是先走路。 Java URL类是你需要做的:

URL url = new URL("http://blah.com......");

if (url.getPath().endsWith(".asf") {

   // your code here
}

使用字边界:

.asf

May be you have to double escape in java.

5月底

.*.asf$

不线末

.*.[^a-zA-Z].*

下一次最好检查是假设,顺序要么在座尾,要么在中间,然后是问答:

if (data.endsWith(".asf") || data.contains(".asf?"))

this only matches when .asf is at the end of the string or right before a ?

Pattern.compile("\.asf(\?|$)")
