下面是一个简单的代码示例,演示了如何将服务器文件路径转换为URL: importjava.io.File;importjava.net.MalformedURLException;importjava.net.URL;publicclassFileToUrlConverter{publicstaticURLconvert(StringfilePath)throwsMalformedURLException{Filefile=newFile(filePath);StringabsolutePath=file.getAbsolutePath();Strin...
Filefile=newFile("C:/example/myfile.txt");// 创建一个文件对象,此处用实际文件路径替换 1. new File("C:/example/myfile.txt"):用实际文件路径替换,确保路径正确。 3. 将文件对象转换为URL 在创建了File对象后,我们可以调用toURI()方法将其转换为URI格式,然后使用toURL()方法转换成URL格式。 try{URL...
