我尝试从 URL(我的 DropBox 帐户)创建如下所示的 fil,然后将其作为附件添加到 MimeMessageHelper,但我收到 FileNotFoundException
。我可能做错了什么?
String[] attachments = {"https://dl.dropboxusercontent.com/s/XXXX/my%20Letter.docx"};
for (String attachment : attachments) {
FileSystemResource file = new FileSystemResource("url:" + attachment);
message.addAttachment(file.getFilename(), file);
}
错误:
Caused by: org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: IOException while sending message;
nested exception is:
java.io.FileNotFoundException: url:https:\dl.dropboxusercontent.com\s\XXXX\my%20Letter.docx (The filename, directory name, or volume label syntax is incorrect); message exceptions (1) are:
Failed message 1: javax.mail.MessagingException: IOException while sending message;
nested exception is:
java.io.FileNotFoundException: url:https:\dl.dropboxusercontent.com\s\XXXX\my%20Letter.docx (The filename, directory name, or volume label syntax is incorrect)

如何从 Http URL 创建 FileSystemResource
?
最佳答案
您可以使用 UrlResource
代替文件系统资源,或者使用某些 http 客户端下载文件,然后将其附加到电子邮件中。
例如:
URL website = new URL("http://someurl");
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream("some temporary name");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
然后使用FileSystemResource
附加它
您可以使用 http 客户端来实现此目的,例如:okhttp
