How to use FileUtils IO correctly?
提问by Buras
I tried to use method (credits to Shenyuan Lu):
我尝试使用方法（归功于沉远路）：
org.apache.commons.io.FileUtils.copyURLToFile(URL, File)
org.apache.commons.io.FileUtils.copyURLToFile(URL, File)
Precisely:
恰恰：
org.apache.commons.io.FileUtils.copyURLToFile(driver.getCurrentUrl(), "C:\\Users\\myDocs\\myfolder\myFile.pdf");
org.apache.commons.io.FileUtils.copyURLToFile(driver.getCurrentUrl(), "C:\\Users\\myDocs\\myfolder\myFile.pdf");
However,Eclipseis underlining the copyURLToFileand suggesting to use copyFile. When I switch to copyFile, it suggests to use copyURLToFileagain???
但是，Eclipse强调copyURLToFile并建议使用copyFile. 当我切换到 时copyFile，它建议copyURLToFile再次使用？？？

According to the FileUtils#copyURLToFile() API...
根据FileUtils#copyURLToFile() API...
The first parameter needs to be a URLobject, and the second parameter needs to be a FileObject. You are passing Strings as both args. Try...
第一个参数需要是一个URL对象，第二个参数需要是一个File对象。您将字符串作为两个参数传递。尝试...
org.apache.commons.io.FileUtils.copyURLToFile(new URL(driver.getCurrentUrl()), new File("C:\Users\myDocs\myfolder\myFile.pdf"));
Also, since this method throws an exception, you either need to make your method throw an exception, or surround the statement in a try {} catch{} block.
此外，由于此方法抛出异常，您需要让方法抛出异常，或者将语句括在 try {} catch{} 块中。
e.g.
例如
try {
org.apache.commons.io.FileUtils.copyURLToFile(new URL(driver.getCurrentUrl()), new File("C:\Users\myDocs\myfolder\myFile.pdf"));
} catch (Exception x) { x.printStackTrace(); }
