fastlane.swift 在范围内找不到“ENV”

Question

我是 fastlane 的新手，试图读取fastfile.swift中的环境变量，其中包含以下内容

import Foundation

class Fastfile: LaneFile {
    .
    .
    .

    func createRCBuildLane() {
        beforeAll()
        ensureGitBranch(branch: "qa")
        let commitMessage = "RC_Build_Version_" + getVersionNumber(target: "Example App") + "_Build_" + getBuildNumber()
        addGitTag(buildNumber: .userDefined(commitMessage), force: true)
        pushGitTags(force: true)
        createPullRequest(apiToken: "*****", repo: "Example/iOS_ble_client", title: commitMessage, base: "master")
        slackMessage(withMessage: "Example App RC Release:\n" + commitMessage)
    }

    .
    .
    .

    func beforeAll() {
//        updateFastlane()
    }

    func matchDevelopmentCertificateLane() {
        match(type: "development")
    }

    func matchAdHocCertificateLane() {
        match(type: "adhoc")
    }

    func matchDistributionCertificateLane() {
        match()
    }

    func slackMessage(withMessage message: String) {
        slack(
            message: .userDefined(message),
            channel: "#example-ios",
            slackUrl: "https://hooks.slack.com/services/###/###/###",
            payload: ["Version:": getVersionNumber(target: "Example App"), "Build:": getBuildNumber()],
            success: true
        )
    }
}

我想通过 ENV 传递apiToken而不是对其进行硬编码。 谁能在这里指出我正确的方向？

我试过了

    func createRCBuildLane() {
        beforeAll()
        ensureGitBranch(branch: "qa")
        let commitMessage = "RC_Build_Version_" + getVersionNumber(target: "Example App") + "_Build_" + getBuildNumber()
        addGitTag(buildNumber: .userDefined(commitMessage), force: true)
        pushGitTags(force: true)
        createPullRequest(apiToken: ENV["API_TOKEN"], repo: "Example/iOS_ble_client", title: commitMessage, base: "master")
        slackMessage(withMessage: "Example App RC Release:\n" + commitMessage)
    }

但收到此错误Fastfile.swift:37:37: cannot find 'ENV' in scope

Answer 1

要快速访问环境变量，您应该使用ProcessInfo 。 例如， Fastfile.swift中有一个示例代码：

class Fastfile: LaneFile {
    
    func testLane() {
        desc("Description of what the lane does")
        
        if let apiToken = ProcessInfo.processInfo.environment["API_TOKEN"] {
            NSLog("API TOKEN: \(apiToken)")
        }
        else {
            NSLog("Error: No token.")
        }
    }
}

现在您可以设置环境变量并运行您的车道：

$ export API_TOKEN='CACD1B9D-56AA-41F0-BDE3-457DDA30A8D4'
$ fastlane testLane 

输出：

...
[13:56:58]: $ ./FastlaneRunner lane testLane swiftServerPort 2000 > /dev/null
[13:56:59]: ▸ 2022-05-31 13:56:59.494 FastlaneRunner[34213:828339] API TOKEN: CACD1B9D-56AA-41F0-BDE3-457DDA30A8D4
[13:56:59]: fastlane.tools finished successfully 🎉

检查项目的fastlane文件夹中是否有.env隐藏文件。 .env是配置项目的环境变量，而不是系统环境变量。 如果API_TOKEN在.env中，则配置没有问题，可以在Applefile中查看是否可以获取指定的环境变量值
