[英]Java mailto Illegal character colon?
im trying to send an email with an attachment, but it keeps saying: 我试图发送带有附件的电子邮件,但一直在说:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Illegal character in opaque part at index 64: mailto:recipient@mailserver.com?subject=ThePDFFile&attachment=C:\Users\Rascal\AppData\Local\Temp\FreelancerList-16-12-2014_09-227568200505392670736.doc
Java Code: Java代码:
Desktop desktop = Desktop.getDesktop();
String message = "mailto:recipient@mailserver.com?subject=ThePDFFile&attachment=\""+path;
URLEncoder.encode(message, "UTF-8");
URI uri = URI.create(message);
desktop.mail(uri);
Should be the colon right? 应该是冒号吧? But why???
但为什么???
You're calling URLEncoder.encode
, but ignoring the result. 您正在调用
URLEncoder.encode
,但是忽略了结果。 I suspect you were trying to achieve something like this: 我怀疑您正在尝试实现以下目标:
String encoded = URLEncoder.encode(message, "UTF-8");
URI uri = URI.create(encoded);
... although at that point you'll have encoded the colon after the mailto
part as well. ...尽管此时您还将在
mailto
部分之后对冒号进行编码。 I suspect you really want something like: 我怀疑您真的想要这样的东西:
String query = "subject=ThePDFFile&attachment=\""+path;
String prefix = "mailto:recipient@mailserver.com?";
URI uri = URI.create(prefix + URLEncoder.encode(query, "UTF-8"));
Or even encoding just the values: 甚至只编码值:
String query = "subject=" + URLEncoder.encode(subject, "UTF-8");
+ "&attachment=" + URLEncoder.encode(path, "UTF-8"));
URI uri = URI.create("mailto:recipient@mailserver.com?" + query);
... or create the URI
from the various different parts separately, of course. ...或者当然可以从各个不同的部分分别创建
URI
。
