在我的网页中，我向 WCF 服务发出 Ajax 请求。如果服务抛出错误，则在 JSON 中传回。然后，JavaScript 错误处理程序会显示一个隐藏的 div，其中包含预先填充了我的详细信息的 mailto URL，以便团队成员（这是一个小型内部应用程序）可以向我发送错误，包括堆栈跟踪。以下是测试运行生成的 URL 示例：

那是 2354 个字符长。
其他答案表明，超过 2000 个字符的 URL 不是一个好主意，因为某些浏览器可能会遇到这些问题。但是浏览器是否以任何方式解析了 mailto URL，或者它们是否立即传递给默认邮件工具？如果交给他们，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？
