mailto URL的最大实际长度是多少? [英] What is the maximum practical length of a mailto URL?

问题描述

在我的网页中，我向WCF服务发出Ajax请求.如果服务抛出错误，则将其传递回JSON.然后，JavaScript错误处理程序将显示一个隐藏的div，该div的mailto URL预先填充了我的详细信息，以便团队成员(这是一个小型内部应用程序)可以向我发送包括堆栈跟踪在内的错误.这是一个示例，它是通过测试运行得到的URL:

In my web page I make an Ajax request to a WCF service. If the service throws an error then that is passed back in the JSON. The JavaScript error handler then reveals a hidden div with a mailto URL prepopulated with my details so that team members (this is a small internal app) can send me the error including the stack trace. Here's an example resulting URL from a test run:

长度为2354个字符.

That's 2354 characters long.

其他答案提示，超过2000个字符的URL是一个坏主意，因为某些浏览器可能会为此感到困扰.但是浏览器是否以任何方式解析mailto URL，还是将它们立即交给默认的邮件工具?如果将它们传递给他人，是否有人拥有各种邮件工具(尤其是Outlook)可以处理的mailto URL长度的数据?

Other answers suggest that URLs above 2000 characters are a bad idea as some browsers may struggle with them. But are mailto URLs parsed in any way by the browser or are they handed immediately on to the default mail tool? If they are handed on, does anyone have data on the length of mailto URLs that various mail tool (and in particular Outlook) can handle?

推荐答案

如这里 -是的，浏览器将在发送之前解析URL -Safari和大多数电子邮件客户端没有硬性限制(取决于可用的CPU和RAM)

As noted here - yes the browser will parse the URL before sending it - Safari and most email clients have no hard limit (depends on available CPU and RAM)
