我需要验证浏览器上显示的word文件的内容。所以我下载了doc文件。 我的下载代码如下：
private String downloader(WebElement element, String attribute) throws IOException, NullPointerException, URISyntaxException {
localDownloadPath = "c:\\downloads";
fileToDownloadLocation = "https://xyz.abc.com/link1/docs/"+element.getAttribute(attribute);
if (fileToDownloadLocation.trim().equals("")) throw new NullPointerException("The element you have specified does not link to anything!");
fileToDownloadLocation = fileToDownloadLocation.replaceAll(" ","%20");
URL fileToDownload = new URL(fileToDownloadLocation);
HttpClient client = HttpClientBuilder.create().build();
HttpsURLConnection con = (HttpsURLConnection)fileToDownload.openConnection();
System.out.println(con);
//for cookies management
// BasicHttpContext localContext = new BasicHttpContext();
HttpClientContext localContext = HttpClientContext.create();
LOG.info("Mimic WebDriver cookie state: " + this.mimicWebDriverCookieState);
if (this.mimicWebDriverCookieState) {
localContext.setAttribute(ClientContext.COOKIE_STORE, mimicCookieState(this.driver.manage().getCookies()));
}
//core downloading part
HttpGet request = new HttpGet(fileToDownload.toURI());
LOG.info("Sending GET request for: " + request.getURI());
HttpResponse response = client.execute(request, localContext);
this.httpStatusOfLastDownloadAttempt = response.getStatusLine().getStatusCode();
LOG.info("HTTP GET request status: " + this.httpStatusOfLastDownloadAttempt);
File downloadedFile = new File(this.localDownloadPath + fileToDownload.getFile().replaceFirst("/|\\\\", ""));
if (downloadedFile.canWrite() == false) downloadedFile.setWritable(true);
LOG.info("Downloading file: " + downloadedFile.getName());
FileUtils.copyInputStreamToFile(response.getEntity().getContent(), downloadedFile);
response.getEntity().getContent().close();
String downloadedFileAbsolutePath = downloadedFile.getAbsolutePath();
LOG.info("File downloaded to '" + downloadedFileAbsolutePath + "'");
return downloadedFileAbsolutePath;
}
它适用于http网站。它甚至适用于一个https站点。但是，当我尝试其他https网站时，我收到如下错误：

我无法弄清楚我做错了什么。有人可以帮忙吗？ 我们热烈欢迎任何形式的帮助。
答案 0 :(得分：0)
Java 7引入了默认启用的SNI支持。某些配置错误的服务器会发送＆＃34;无法识别的名称＆＃34; SSL握手中的警告，除Java外，大多数客户端都会忽略。
尝试将-Djsse.enableSNIExtension=false添加到Java命令参数中，看看它是否有帮助。
在下载程序方法中，添加System.setProperty("jsse.enableSNIExtension", "false")并查看是否有帮助。
