有没有办法在不使用第三方API的情况下从input file tag
获取文件的完整路径?
<form method="post" action="SendTheFileName">
<div id="Files_to_be_shared">
<input type="file" id="File" name="FileTag" />
<input type="submit" value="Share" />
</div>
</form>
来自servlet的Snippet:
String fileName = request.getParameter("FileTag");
我从上面的java代码得到的只是所选文件的名称。如何获取文件的完整路径?

这个问题已在其他主题中得到解答,我认为这2中的任何一个都可以帮助你:

为了更多地完成我的答案,因为你添加了java标签,在这里我将包含一些代码片段,显示一些你可以从文件中获得的最常见的信息,但是从java perspective:
package test;
import java.io.File;
import java.io.IOException;
public class FilePaths {
public static void main(String[] args) throws IOException {
String[] fileArray = {
"C:\\projects\\workspace\\testing\\f1\\f2\\f3\\file5.txt",
"folder/file3.txt",
"../testing/file1.txt",
"../testing",
"f1/f2"
};
for (String f : fileArray) {
displayInfo(f);
}
}
public static void displayInfo(String f) throws IOException {
File file = new File(f);
System.out.println("========================================");
System.out.println(" name:" + file.getName());
System.out.println(" is directory:" + file.isDirectory());
System.out.println(" exists:" + file.exists());
System.out.println(" path:" + file.getPath());
System.out.println(" absolute file:" + file.getAbsoluteFile());
System.out.println(" absolute path:" + file.getAbsolutePath());
System.out.println("canonical file:" + file.getCanonicalFile());
System.out.println("canonical path:" + file.getCanonicalPath());
}
}
