Kaw*_*ili 5 html java windows-7
我迫切需要您在解决Windows-7问题方面的专业知识.
场景:我有一个基于框架的帮助包,设置用于上下文相关的帮助调用.Java应用程序能够通过将表示所需HTML命名锚点的标记传递给名为pophelp的HTML文件来控制帮助包打开的页面.此文件具有javascripting,它从URL末尾读取传递的标记,并将其映射到帮助包中的相应HTML文件并打开它.
问题:上述方案适用于Windows XP,但不再适用于Windows 7.
来自Java应用程序的调用机制: rundll32 url.dll,FileProtocolHandler文件://filepath/pophelp.html？标记
到目前为止的调查结果摘要:似乎url.dll不再允许在Windows 7中使用URL传递参数.参数被剥离.我也尝试使用来自Java的Desktop.getDesktop().browse()进行相同类型的调用,但它似乎也在.html之后删除了所有参数.
示例代码:
适用于Windows XP的原始呼叫 -
运行命令: rundll32 url.dll,FileProtocolHandler文件:// C:\ Program Files\App System\App-Editor-8.0.1\help\pophelp.html？TAG = callsubflow
结果:？TAG =未传递callsubflow.
使用Desktop.getDesktop()的新代码.browse() -
public static void main(String[] args) {
String url = "file:///C:/Program Files/App System/App-Editor-8.0.1/help/pophelp.html?TAG=callsubflow";
try {
if (Desktop.isDesktopSupported()) {
Desktop desktop = Desktop.getDesktop();
if (desktop.isSupported(Desktop.Action.BROWSE)) {
desktop.browse(new URI(url.replace(" ", "%20")));
}
}
} catch (IOException e) {
System.out.println("Unable to open "+url+": "+e.getMessage());
} catch (URISyntaxException e) {
e.printStackTrace();
}
}
结果:？TAG =未传递callsubflow.
任何援助将不胜感激!
我真的不明白为什么 Windows 会删除本地文件上的参数。正如评论中提到的，这似乎是某种奇怪的安全限制。但我曾经遇到过类似的问题，并且我找到了一个也适合这种情况的解决方法。
只需创建一个本地临时 HTML 文件（不带参数）即可将您重定向到所需的文件（带参数）。
看看这两个方法：
// creates w3c conform redirect HTML page
public String createRedirectPage(String url){
return "<!DOCTYPE HTML>" +
"<meta charset=\"UTF-8\">" +
"<meta http-equiv=\"refresh\" content=\"1; url=" + url + "\">" +
"<script>" +
"window.location.href = \"" + url + "\"" +
"</script>" +
"<title>Page Redirection</title>" +
"<!-- Note: don't tell people to `click` the link, just tell them that it is a link. -->" +
"If you are not redirected automatically, follow the <a href='" + url + "'>link</a>";
}
// creates temporary file with content of redirect HTML page
public URI createRedirectTempFile(String url) {
BufferedWriter writer = null;
File tmpFile = null;
try {
// creates temporary file
tmpFile = File.createTempFile("pophelp", ".html", null);
// deletes file when the virtual machine terminate
tmpFile.deleteOnExit();
// writes redirect page content to file
writer = new BufferedWriter(new FileWriter(tmpFile));
writer.write(createRedirectPage(url));
writer.close();
}
catch (IOException e) {
return null;
}
return tmpFile.toURI();
}
现在你可以像这样使用它们：
String url = "file:///C:/Program Files/App System/App-Editor-8.0.1/help/pophelp.html?TAG=callsubflow";
if (Desktop.isDesktopSupported()) {
Desktop desktop = Desktop.getDesktop();
if (desktop.isSupported(Desktop.Action.BROWSE)) {
desktop.browse(createRedirectTempFile(url.replace(" ", "%20")));
}
}
