问题描述
我正在编写一个默认的邮件客户端，以便在有人单击mailto:[email protected]
I am writing a default mail client to handle when someone clicks mailto:[email protected]
craigslist mailto链接的格式为mailto:bob％40example.com
使用此方法时会出现异常.
这是一些简单的代码，可以在c#
craigslist mailto links have the form mailto:bob%40example.com
I get an exception when this is used.
here is some simple code to repeat the problem in c#
System.Uri u1 = new Uri(@"mailto:[email protected]"); // ok so far
System.Uri u2 = new Uri(@"http://somewhere.foo/profile/username%40somewhere.foo"); // still ok
System.Uri u3 = new Uri(@"mailto:bob%40ms.com"); // crash here
问题1:
请勿mailto:bob％40example.com是有效的uri
问题2:
如果它是无效的uri，那么Outlook不会崩溃的原因.
question 1:
shoudn't mailto:bob%40example.com be a valid uri
question 2:
if it is an invalid uri then how is outlook not crashing on it.
我正在使用Visual Studio 2012

推荐答案
RFC 6068( http://www.ietf.org/rfc/rfc6068.txt )(定义了mailto协议)没有不指定％40是将@替换为用户名/域分隔符的有效语法
RFC 6068 (http://www.ietf.org/rfc/rfc6068.txt), which defines the mailto protocol, does not specify that %40 is a valid syntax to replace @ as a username/domain separator.
它确实指定如果用户名包含@，例如在hello@[email protected]情况下，则可以使用％40将其转义为hello%[email protected].但是没有地方指出hello%40domain.com是有效的mailto URI.
It does specify that if a username contains a @, such as in the case hello@[email protected], you can use %40 to escape it to hello%[email protected]. But nowhere does it state that hello%40domain.com would be a valid mailto URI.
如果Microsoft决定在Outlook中支持它，那仍然不会改变事实，即权威的RFC没有定义它-所以我想说，微软可能出于以下原因将其放入其中健壮性，或者这是它们为％xx语法解析任何URI的副作用...
And if Microsoft decided to support it in Outlook, that still doesn't change the fact that the RFC, which is authoritative, doesn't define it -- so I'd say, Microsoft probably put it in for reasons of robustness, or maybe it's a side-effect of them parsing any URI for %xx syntax...
