包括两个图像，首先是Firefox：参见https://i.imgur.com/ZSCHXOM.jpg
第二是Edge：参见https://i.imgur.com/FTIiHpS.jpg
Firefox刚获得ann.JPG
Edge获取C：\ Users \ jimwin7a \ Pictures \ ann.JPG
这里是确切的错误：
Exception is ;java.nio.file.InvalidPathException: Illegal char <:> at index 26: \stohere\uploads \imgdogs\C:Usersjimwin7aPicturesann7.JPG
您可以看到Edge正在得到：\ C：Usersjimwin7aPicturesann7.JPG
因此，我如何重新设计servlet以使其也可以在Edge中工作？
我希望这可以帮助某人，我可以正常工作。
首先我添加了这个：
String fileName = getFileName(filePart).toString();
getFileName来自另一个S.O.文章：
private String getFileName(Part part) {
String contentDisp = part.getHeader("content-disposition");
System.out.println("content-disposition header= "+contentDisp);
String[] tokens = contentDisp.split(";");
for (String token : tokens) {
if (token.trim().startsWith("filename")) {
return token.substring(token.indexOf("=") + 2, token.length()-1);
}
}
return "";
}
但是只获取file.jpg，即ann.jpg，我通过另一个函数运行：
此行
String acfilename = fixSubmittedFileName(fileName);
功能是：
private static String fixSubmittedFileName(String fileName) {
String nfname = fileName;
nfname = nfname.replace("\\", "/");
int dot = nfname.lastIndexOf('/');
String afname = (dot == -1) ? nfname : nfname.substring(dot + 1);
return afname;
}
在Chrome，Edge，Firefox和IE 11上测试，可以正常工作。
感谢您的回答和帮助。
