MacOS NSWorkspace.shared.open“无法打开应用程序。-50”

Question

在NSWorkspace.shared.open()中的其他Stack Overflow code examples之后，我想到了这一点：

  @IBAction func mailFileVacuum(_ sender: NSButton) {
    let receiver = sender.alternateTitle
    let sendAddress = String(format: "mailto:%@@filevacuum.com?subject=FileVacuum %@", receiver, receiver).addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!

    NSLog("receiver %@", receiver)

    let mailUrl = URL(string: sendAddress)

    NSLog("mailUrl %@", mailUrl!.absoluteString)

    if NSWorkspace.shared.open(mailUrl!) {
        print("Default browser was successfully opened to send email. ??")

    }
  }

☝️让我们得到这个?

我尝试更改默认浏览器，这不是问题。

NSLog(mailUrl)记录此mailto%3AFeedback%40filevacuum.com%3Fsubject=FileVacuum%20Feedback

看起来不错maybe ...

¿Que Paso？

Answer 1

您不应对整个 URL进行百分比编码；而是它的各个组成部分。参见Apple URL Scheme Reference。

格式正确的网址应如下所示（即应输出NSLog(mailUrl)）

mailto:Feedback@filevacuum.com?subject=FileVacuum%20Feedback
