Question

我有一个PowerShell脚本从SFTP下载文件，然后尝试将它们提交给git，但是我在最后一步遇到了问题。

try
{
    # Load WinSCP .NET assembly
   Add-Type -Path  "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "myhostname"
        UserName = "myusername"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 myfingerprint"
        #GiveUpSecurityAndAcceptAnySshHostKey = "true" 
    }

    $session = New-Object WinSCP.Session

    try
    {
        New-Item -ItemType directory -Path "C:\tempfolder"

        # Connect
        $session.Open($sessionOptions)

        # Download files
        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary

        $transferResult =
            $session.GetFiles("/BE_Test3rdPartyUpload2VSTS/Project1/upload/*", "c:\tempfolder\*", $False, $transferOptions)

        # Throw on any error
        $transferResult.Check()

        # Print results
        foreach ($transfer in $transferResult.Transfers)
        {
            Write-Host "Download of $($transfer.FileName) succeeded"
        }

        git config --global user.email "myusername"
        git config --global user.name "myname"

        git pull --rebase origin master
        git push origin master


        git add .
        git commit -m "Add existing file"
        git push origin "master"
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}

我遇到的错误是：

要将更改推送到master分支，您应该使用以下方面更改powershell脚本：

取消选择PowerShell任务的标准错误失败选项

由于大多数git命令显示非标准输出，因此您需要取消选择PowerShell任务的标准错误失败选项，否则PowerShell将失败。

git repo网址中的提供商凭据

将更改推送到远程仓库时，您需要提供凭据。您可以在git repo URL中使用PAT或备用凭据。 git repo URL的格式如下：

https://Personal%20Access%20Token:{PAT}@{account}.visualstudio.com/{project}/_git/{repo}
https://{AlternateUserName}:{AlternatePassword}@{account}.visualstudio.com/{project}/_git/{repo}

所以你应该按下命令：

git push https://Personal%20Access%20Token:{PAT}@{account}.visualstudio.com/{project}/_git/{repo} master

或

git push https://{AlternateUserName}:{AlternatePassword}@{account}.visualstudio.com/{project}/_git/{repo} master

结帐到构建分支

在构建源目录中，默认情况下git repo处于HEAD分离状态，因此您需要通过以下方式切换到构建分支：
```
git checkout $(Build.SourceBranchName)
```
删除不必要的命令

脚本中的两个命令下面似乎没有对本地master分支和远程master分支进行任何更改：
```
git pull --rebase origin master
git push origin master
```

因此，您可以在脚本中删除它们。

以下是更改后的PowerShell脚本的示例：

try
{
    # Load WinSCP .NET assembly
   Add-Type -Path  "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "myhostname"
        UserName = "myusername"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 myfingerprint"
        #GiveUpSecurityAndAcceptAnySshHostKey = "true" 
    }

    $session = New-Object WinSCP.Session

    try
    {
        New-Item -ItemType directory -Path "C:\tempfolder"

        # Connect
        $session.Open($sessionOptions)

        # Download files
        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary

        $transferResult =
            $session.GetFiles("/BE_Test3rdPartyUpload2VSTS/Project1/upload/*", "c:\tempfolder\*", $False, $transferOptions)

        # Throw on any error
        $transferResult.Check()

        # Print results
        foreach ($transfer in $transferResult.Transfers)
        {
            Write-Host "Download of $($transfer.FileName) succeeded"
        }

        git config --global user.email "myusername"
        git config --global user.name "myname"

        git checkout $(Build.SourceBranchName)

        git add .
        git commit -m "Add existing file"
        git push https://Personal%20Access%20Token:tp3iai4yextum26xa6k6qbflhjrvpt4jcaak8fkhbhlpis7zkndq@marinaliu.visualstudio.com/Git2/_git/product1 master 
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}

错误：src refspec master与VSTS中的powershell不匹配
