使用QDesktopServices :: openUrl发送带有换行符的邮件 [英] Sending mail with line breaks using QDesktopServices::openUrl

问题描述

我试图用准备好的主题，接收者和身体使用Qt发送电子邮件。邮件将在系统默认邮件客户端中打开。我正在使用KMail和Qt 5.5在Linux上测试。

这是我打算使用的代码：

  QDesktopServices :: openUrl（QUrl（mailto：？to = [e-mail]& subject = Test& body = line1％0D％0Aline2，QUrl :: TolerantMode））; 
  

邮件窗口打开，主题和收件人都可以。不幸的是，身体的换行不行。我也尝试过< br> ;, \\\
，\r\\\
，但这些都没有。我也尝试过其他方式构建一个 QUrl ，但只会变得更糟。

似乎不是一个KMail问题是因为当将以下内容写入HTML文档时，在Firefox中打开它并点击浏览器中的链接，它完全正是我想要的（包括正文中的换行符）：

 < a href =mailto：？to = [e-mail]& subject = test& body = line1％0D％0Aline2> test< / a> 
  

如何解决换行符问题？

更新：
kmailmailto：？to = [e-mail]& subject = test& body = line1％0D％0Aline2工作似乎是与KMail有关的问题。人们告诉我上面的语法与雷鸟有关。

解决方案

原来是一个KMail错误： https://bugs.kde.org/show_bug.cgi?id=366981

I tried to send an e-mail with a prepared subject, receiver and body using Qt. The mail shall open in the system default mail client. I am testing on Linux with KMail and Qt 5.5.

This is the code I intended to use:

QDesktopServices::openUrl(QUrl("mailto:?to=[e-mail]&subject=Test&body=line1%0D%0Aline2", QUrl::TolerantMode));

The mail window opens, subject and receiver are ok. Unfortunately the line breaks in the body do not work. I also tried <br>, \n, \r\n but none of these worked. I also tried other ways of constructing a QUrl but it only get worse.

It seems not to be an KMail issue because when writing the following into a HTML document, opening it in firefox and clicking the link in the browser, it does exactly what I want (including line breaks in the body text):

<a href="mailto:?to=[e-mail]&subject=test&body=line1%0D%0Aline2">test</a>

How can I fix the line break problem?

UPDATE: kmail "mailto:?to=[e-mail]&subject=test&body=line1%0D%0Aline2" also doesn't work. Seems to be a KMail related problem. People told me the above syntax works with thunderbird.

解决方案

Turned out it is an KMail bug: https://bugs.kde.org/show_bug.cgi?id=366981
