Question

我正在尝试从SEC.gov下载文件，但以下代码无法下载该文件。使用此代码下载的所有文件均为1 KB。

URL Url = null;

try {
    Url= new URL("http://www.sec.gov/Archives/edgar/data/769397/000076939716000079/0000769397-16-000079-xbrl.zip");

} catch (MalformedURLException e) {

    e.printStackTrace();
}

String fullPathFileName = "D:\\0000769397-16-000079-xbrl.zip";

File destinationFile = new File(fullPathFileName);

try {
    FileUtils.copyURLToFile(Url, destinationFile);

} catch (IOException e) {

    e.printStackTrace();

}

如果我使用相同的代码从其他网站下载，它可以正常工作。我还尝试了连接超时和读取超时的copuURLToFile方法。

FileUtils.copyURLToFile()的问题在于它没有向您提供有关其所做工作的任何信息。从命令行尝试wget实用程序：

wget http://www.sec.gov/Archives/edgar/data/769397/000076939716000079/0000769397-16-000079-xbrl.zip
