WebClient client = new WebClient(BrowserVersion.FIREFOX_38);
HtmlPage homePage = null;
// Document doc = null;

synchronized (homePage) {
homePage.wait(5000);
}
System.out.println("file Page : " + homePage.getUrl());
// Document dd = Jsoup.parse(homePage.asXml());
HtmlInput docs= homePage.getFirstByXPath("//input[@id='ctl00_m_g_b265ad4d_cd49_41f3_a9f2_0090f0aa5504_ctl00_gvBidSetsFile_ctl02_ImageButton1']");
homePage = bidDocs.click();
表演可以吗
homePage = bidDocs.click();
在这里单击保存图标下载文件
String docurl=获取主页链接代码>
如果我能得到链接,我可以使用BufferedStream
下载文件
File file = new File("C:/TRY/file/abc.zip");
BufferedInputStream in = null;
FileOutputStream fout = null;
try {
in = new BufferedInputStream(new URL(docUrl).openStream());
fout = new FileOutputStream(file);
final byte data[] = new byte[1024];
int count;
while ((count = in.read(data, 0, 1024)) != -1) {
fout.write(data, 0, count);
}
} finally {
if (in != null) {
in.close();
}
if (fout != null) {
fout.close();
}
}
我必须在这里使用HTMLUNIT
,因为它是javascript
,iframe
站点。
我感谢你的帮助
非常感谢您选择文件标签。
HtmlInput download = pageCheck.getByXPath("//input[@title='Download']");
