在可可应用中运行终端命令 [英] Running terminal commands in in cocoa app

问题描述

在可可应用程序上运行代码以运行某些命令行脚本时，我遇到了问题

I facing a problem when running my code on cocoa app to run some command line scripts

使用命令行工具时，此功能运行平稳，但是当使用带有某些开/关" UI的完整可可应用时，则根本无法工作

This function run smoothly when using Command line tool but when using full cocoa app with some On Off UI it not working at all

我的脚本应该打开/关闭http&https代理

My script should turn on/off the http & https proxy

这是我的职能:

    private func runTask(_ cmd: String) {

        // Create a Task instance
        let task = Process()

        // Set the task parameters
        task.launchPath = "/bin/sh"
        task.arguments = ["-c", String(format:"%@", cmd)]

        // Create a Pipe and make the task
        // put all the output there
        let pipe = Pipe()
        task.standardOutput = pipe

        // Launch the task
        task.launch()

        // Get the data
        let data = pipe.fileHandleForReading.readDataToEndOfFile()
        guard let output = NSString(data: data, encoding: String.Encoding.utf8.rawValue) else { return }

        print(output)
    }

这是我完整的ViewController类:

And here is my full ViewController class:

import Cocoa

class ViewController: NSViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    @IBAction func onButtonTapped(_ sender: NSButton) {
        print("onButtonTapped")
        let selected: Switch = .on
        let listOfNetworkCommands: String = [
            #"networksetup -setwebproxystate "Wi-fi" \#(selected)"#, // switch http proxy
            #"networksetup -setsecurewebproxystate "Wi-fi" \#(selected)"#, // switch https proxy
            #"networksetup -setpassiveftp "Wi-fi" \#(selected)"# // switch passive ftp
            ].joined(separator: " && ")

        runTask(listOfNetworkCommands)
    }

    @IBAction func offButtonTapped(_ sender: NSButton) {
        print("onButtonTapped")
        let selected: Switch = .off
        let listOfNetworkCommands: String = [
            #"networksetup -setwebproxystate "Wi-fi" \#(selected)"#, // switch http proxy
            #"networksetup -setsecurewebproxystate "Wi-fi" \#(selected)"#, // switch https proxy
            #"networksetup -setpassiveftp "Wi-fi" \#(selected)"# // switch passive ftp
            ].joined(separator: " && ")

        runTask(listOfNetworkCommands)
    }

    enum Switch: String {
        case on, off
    }

    private func runTask(_ cmd: String) {

        // Create a Task instance
        let task = Process()

        // Set the task parameters
        task.launchPath = "/bin/sh"
        task.arguments = ["-c", String(format:"%@", cmd)]

        // Create a Pipe and make the task
        // put all the output there
        let pipe = Pipe()
        task.standardOutput = pipe

        // Launch the task
        task.launch()

        // Get the data
        let data = pipe.fileHandleForReading.readDataToEndOfFile()
        guard let output = NSString(data: data, encoding: String.Encoding.utf8.rawValue) else { return }

        print(output)
    }

}

知道为什么我的功能没有在可可应用程序中触发吗?

Any idea why my function not triggered in the cocoa app?

推荐答案

通过在Cocoa应用程序中禁用应用程序沙箱"(位于项目"应用程序目标>功能"选项卡>应用程序沙箱"开关下)，可以找到简单的答案.您会发现自己被沙箱异常阻止.禁用沙箱应该可以解决您的问题.

Simple answer is found by disabling App Sandbox in your Cocoa Application (found under your Project app target > Capabilities tab > App Sandbox switch). You'll find that you're being blocked by a sandbox exception. Disabling sandboxing should fix your issue.

如果您为应用程序名称或沙盒进程进行过滤，也可以在Console.app中看到此内容.启用沙箱功能后，您可能会有一个这样的条目:

You can also see this in Console.app if you filter for your app name or the sandboxd process. You'll likely have an entry like this when sandboxing is enabled:

错误00:21:57.502273 +0000沙盒沙盒:sh(17363)deny(1)文件读取数据/dev/ttys003

error 00:21:57.502273 +0000 sandboxd Sandbox: sh(17363) deny(1) file-read-data /dev/ttys003
