在项目中看到以前同事写的自动打包并上传蒲公英脚本，就萌发了用原生swift或者OC可不可以编写脚本的想法。查阅相关资料后发现是可行的。

1、Process是一个可以执行终端命令的类

我们给Process扩展一个便捷方法执行终端命令

extension Process {
    
    /// 执行命令
    /// - Parameters:
    ///   - launchPath: 命令路径
    ///   - arguments: 命令参数
    ///   - currentDirectoryPath: 命令执行目录
    ///   - environment: 环境变量
    /// - Returns: 返回执行结果
    static func executable(launchPath:String,
                           arguments:[String],
                           currentDirectoryPath:String? = nil,
                           environment:[String:String]? = nil)->Pipe{
        let process = Process()
        process.launchPath = launchPath
        process.arguments = arguments
        if let environment = environment {
            process.environment = environment
        }
        if let currentDirectoryPath = currentDirectoryPath {
            process.currentDirectoryPath = currentDirectoryPath
        }
        let pipe = Pipe()
        process.standardOutput = pipe
        process.launch()
        return pipe
    }
}
复制代码

2、xcodebuild命令

Clean

xcodebuild clean
           -workspace <workspaceName>
           -scheme <schemeName>
           -configuration <Debug|Release>
复制代码

Export

xcodebuild -exportArchive
           -archivePath <xcarchivepath>
           -exportPath <destinationpath>
           -exportOptionsPlist <plistpath>
复制代码

参考文章：xcodebuild命令介绍

3、使用 SPM 搭建开发或者直接使用xcode的创建一个命令行程序项目

$ mkdir SwiftCommandLineTool
$ cd SwiftCommandLineTool
$ swift package init --type executable
复制代码

最后一行的 type executable 参数将告诉 SPM，我们想创建一个 CLI，而不是一个 Framework。

封装一个打包上传相关的工具

extension String{
    func appPath(_ value:String) -> String {
        if self.hasSuffix("/") {
            return self + value
        }
        return self + "/" + value
    }
}
struct IpaTool {
    
    struct Output {
        var pipe:Pipe
        var readData:String
        init(pipe:Pipe) {
            self.pipe = pipe
            self.readData = String(data: pipe.fileHandleForReading.readDataToEndOfFile(), encoding: String.Encoding.utf8) ?? ""
        }
    }
    enum Configuration:String {
        case debug = "Debug"
        case release = "Release"
    }
    
    var workspace:String{
        projectPath.appPath("\(projectName).xcworkspace")
    }
    ///scheme
    var scheme:String
    ///Debug|Release
    var configuration:Configuration
    ///编译产物路径
    var xcarchive:String{
        exportIpaPath.appPath("\(projectName).xcarchive")
    }
    ///配置文件路径
    var exportOptionsPlist:String
    ///导出ipa包的路径
    var exportIpaPath:String
    ///项目路径
    let projectPath:String
    ///项目名称
    let projectName:String
    ///存放打包目录
    let packageDirectory:String
    ///蒲公英_api_key
    let pgyerKey:String
    
    ///
    /// - Parameters:
    ///   - projectPath: 项目路径
    ///   - configuration: Debug|Release
    ///   - exportOptionsPlist: 配置文件Plist的路径
    ///   - pgyerKey: 上传蒲公英的key
    /// - Throws: 抛出错误
    init(projectPath:String,
      configuration:Configuration,
      exportOptionsPlist:String,
      pgyerKey:String) throws {
     self.projectPath = projectPath
     self.configuration = configuration
     self.exportOptionsPlist = exportOptionsPlist
     self.pgyerKey = pgyerKey
     let manager = FileManager.default
     var allFiles = try manager.contentsOfDirectory(atPath: projectPath)
     projectName = allFiles.first(where: { $0.hasSuffix(".xcodeproj")  })?.components(separatedBy: ".").first ?? ""
     packageDirectory = NSHomeDirectory()
         .appPath("Desktop/\(projectName)_ipa")
     
     allFiles = try manager.contentsOfDirectory(atPath: projectPath.appPath("\(projectName).xcodeproj/xcshareddata/xcschemes")
     )
     scheme = allFiles[0].components(separatedBy: ".").first ?? ""
     let formatter = DateFormatter()
     formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
     exportIpaPath = packageDirectory.appPath(formatter.string(from: Date()))
 }
}
复制代码

封装执行clean，archive，exportArchive

extension IpaTool{
    /// 执行 xcodebuild clean
    func clean()->Output{
        let arguments = ["clean",
                         "-workspace",
                         workspace,
                         "-scheme",
                         scheme,
                         "-configuration",
                         configuration.rawValue,
                         "-quiet",
                        ]
        return Output(pipe: Process.executable(launchPath: "/usr/bin/xcodebuild", arguments: arguments))
    }
    /// 执行 xcodebuild archive
    func archive()->Output{
        let arguments = ["archive",
                         "-workspace",
                         workspace,
                         "-scheme",
                         scheme,
                         "-configuration",
                         configuration.rawValue,
                         "-archivePath",
                         xcarchive,
                         "-quiet",
                        ]
        return Output(pipe: Process.executable(launchPath: "/usr/bin/xcodebuild", arguments: arguments))
    }
    /// 执行 xcodebuild exportArchive
    func exportArchive()->Output{
        let arguments = ["-exportArchive",
                         "-archivePath",
                         xcarchive,
                         "-configuration",
                         configuration.rawValue,
                         "-exportPath",
                         exportIpaPath,
                         "-exportOptionsPlist",
                         exportOptionsPlist,
                         "-quiet",
                        ]
        return Output(pipe: Process.executable(launchPath: "/usr/bin/xcodebuild", arguments: arguments))
    }
}
复制代码

准备工作完成，我们现在来编写打包代码

do{
    let ipaTool = try IpaTool(projectPath: "/Users/gree/gmall_ios",
                          configuration: .debug,
                          exportOptionsPlist: "/Users/gree/Desktop/greeMall_ipa/2021-06-03 09:48:40/ExportOptions.plist",
                          pgyerKey: "xxxxxx")
    
    print(ipaTool)
    print("执行clean")
    var output = ipaTool.clean()
    if output.readData.count > 0 {
        print("执行失败clean error = \(output.readData)")
        exit(-1)
    }
    print("执行archive")
    output = ipaTool.archive()
    if !FileManager.default.fileExists(atPath: ipaTool.xcarchive) {
        print("执行失败archive error = \(output.readData)")
        exit(-1)
    }
    print("执行exportArchive")
    output = ipaTool.exportArchive()
    
    if !FileManager.default.fileExists(atPath: ipaTool.exportIpaPath.appPath("\(ipaTool.scheme).ipa")) {
        print("执行失败exportArchive error =\(output.readData)")
        exit(-1)
    }
    print("导出ipa成功\(ipaTool.exportIpaPath)")
}catch{
    print(error)
}
复制代码

注意projectPath使用自己项目路径，exportOptionsPlist建议先手动打一次包来获取

运行结果

IpaTool(scheme: "greeMall", configuration: SwiftCommandLineTool.IpaTool.Configuration.debug, exportOptionsPlist: "/Users/gree/Desktop/greeMall_ipa/2021-06-03 09:48:40/ExportOptions.plist", exportIpaPath: "/Users/gree/Desktop/greeMall_ipa/2021-06-07 13:59:21", projectPath: "/Users/gree/gmall_ios", projectName: "greeMall", packageDirectory: "/Users/gree/Desktop/greeMall_ipa", pgyerKey: "51895949ad44dcc3934f47c17aa0c0e5")
执行clean
执行archive
执行exportArchive
导出ipa成功/Users/gree/Desktop/greeMall_ipa/2021-06-07 13:59:21
Program ended with exit code: 0

4、把ipa包上传蒲公英

我这里上传文件使用Alamofire，如果你们熟悉URLSession用它也行

在Package.swift

let package = Package(
    name: "SwiftCommandLineTool",
    platforms: [.macOS("10.12")],
    dependencies: [
        .package(name: "Alamofire",
                 url: "https://github.com/Alamofire/Alamofire.git",
                 from: "5.4.3")
    ],
    targets: [
        .target(
            name: "SwiftCommandLineTool",
            dependencies: ["Alamofire"]),
        .testTarget(
            name: "SwiftCommandLineToolTests",
            dependencies: ["SwiftCommandLineTool","Alamofire"]),
    ]
)

复制代码

给IpaTool添加一个上传ipa的函数

//上传蒲公英
    func update(){
       
        let ipaPath = exportIpaPath.appPath("\(scheme).ipa")
        
        let upload = AF.upload(multipartFormData: { formdata in
            formdata.append(pgyerKey.data(using: .utf8)!, withName: "_api_key")
            formdata.append(URL(fileURLWithPath: ipaPath), withName: "file")
        }, to: URL(string: "https://www.pgyer.com/apiv2/app/upload")!)
        
        var isExit = true
        let queue = DispatchQueue(label: "queue")
        upload.uploadProgress(queue: queue) { progress in
            let p = Int((Double(progress.completedUnitCount) / Double(progress.totalUnitCount)) * 100)
            print("上传进度:\(p)%")
        }
        upload.responseData(queue:queue) { dataResponse in
            switch dataResponse.result {
            case .success(let data):
                let result = String(data: data, encoding: .utf8) ?? ""
                print("上传成功:\(result)")
            case .failure(let error):
                print("上传失败: \(error)")
            }
            isExit = false
        }
        //使用循环换保证命令行程序,不会死掉
        while isExit {
            Thread.sleep(forTimeInterval: 1)
        }
    }
复制代码

print("导出ipa成功\(ipaTool.exportIpaPath)")
print("开始上传蒲公英")
ipaTool.update()
复制代码

上传文件的时候使用DispatchQueue.main命令行程序还是会死掉，所以加了一个while循环来保证程序不死。大家有其他方法告送我一下。

5、打代码打包成一个CLl工具（命令行程序）

我这里就不提供教程了，大家可以参考这篇文章：使用 Swift 编写 CLI 工具的入门教程

我不喜欢使用终端所以使用SwiftUI写了一个简单的macOS App

6、一般我们的项目中用了`CocoaPods`我们打包的时候要执行一下pod相关的命令

 // pod install
    func podInstall()->Output{
        var environment = [String:String]()
        /*
         添加环境变量LANG = en_US.UTF-8
         否则这个错误
         [33mWARNING: CocoaPods requires your terminal to be using UTF-8 encoding.
         Consider adding the following to ~/.profile:
         export LANG=en_US.UTF-8
         */
        environment["LANG"] = "en_US.UTF-8"
        /*
         添加环境变量PATH = /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Users/gree/.rvm/bin
         终端运行 echo $PATH 获取
         否则这个错误
         [1mTraceback[m (most recent call last):

        environment["PATH"] = "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Users/gree/.rvm/bin"

        environment["CP_HOME_DIR"] = NSHomeDirectory().appending("/.cocoapods")
        let pipe = Process.executable(launchPath: "/usr/local/bin/pod",
                                    arguments: ["install"],
                                    currentDirectoryPath: projectPath,
                                    environment: environment)
        return Output(pipe: pipe)
    }
