Мощь Groovy: Reading URL Content
Groovy adds some methods to the URL class which make reading data from an URL easy. For example the text property returns the complete contents of the document that is identified by the URL. Or we can use the eachLine() method to loop through each line of the document. Groovy also adds a toURL() to the String class to make a URL object.
def url = "http://www.mrhaki.com/url.html".toURL()
assert '''\
Simple test document
for testing URL extensions
in Groovy.
''' == url.text
def result = []
url.eachLine {
if (it =~ /Groovy/) {
result << it
}
}
assert ['in Groovy.'] == result
url.withReader { reader ->
assert 'Simple test document' == reader.readLine()
}That’s all, just simple.
