Question

我正在编写一个PowerShell脚本来读取日志并生成报告，日志的前缀格式如下例所示：

Job 001, Allan send successfully
Job 002, Kath receive successfully
Job 003, Allan receive failed

示例：

$Logs = Get-content logs.txt
Foreach ($line In $Logs) {
  if ($line[0] -eq "1") {
    $JobType, $Username, $UserID = $line -split ','

    Write-host $JobType
    Write-host $Username
    Write-host $UserID
  } elseif ($line[0] -eq "2") {
    $JobType, $JobID, $UserID, $Action, $Result  = $line -split ',' 

    Write-host $JobType
    Write-host $JobID 
    Write-host $UserID  
    Write-host $Action  
    Write-host $Result
  }  
}

我的最终结果应该是：

#define _WIN32_WINNT 0x600

#include <stdio.h>
#include <wininet.h>

#define BUFLEN 1024

static LPCTSTR acceptTypes[] = {"*/*", NULL};
static const char *postData = "submit=submit&cool=hawk";
static char headers[] = TEXT("Content-Type: multipart/form-data; boundary=abcde\r\n"
                            "--abcde\r\n"
                            "Content-Disposition: form-data; name=\"cool\"\r\n"
                            "testval\r\n"
                            "--abcde\r\n");

int main()
{
    HINTERNET hSession, hConnect, hFile;

    if( ( hSession = InternetOpen(
        "myapp",
        INTERNET_OPEN_TYPE_PRECONFIG,
        NULL,
        NULL,
        0
    ) ) == NULL )
    {
        printf("Couldn't start session. Error %ld\n", GetLastError());
        exit(1);
    }
    printf("Session started\n");

    if( ( hConnect = InternetConnect(
        hSession,
        "localhost",
        INTERNET_DEFAULT_HTTP_PORT,
        NULL,
        NULL,
        INTERNET_SERVICE_HTTP,
        0,
        0
    ) ) == NULL )
    {
        printf("Unable to connect to server. Error %ld\n", GetLastError());
        exit(1);
    }
    printf("Connected to server\n");

    if( ( hFile = HttpOpenRequest(
        hConnect,
        "POST",
        "/test/index.php",
        NULL,
        NULL,
        acceptTypes,
        INTERNET_FLAG_RELOAD,
        0
    ) ) == NULL )
    {
        printf("Unable to open request. Error %ld\n", GetLastError());
        exit(1);
    }
    printf("Opening request..Opened\n");

    unsigned long dataLen = strlen(postData)+1;
    bool res = HttpSendRequest(
        hFile,
        headers,
        -1,
        (char*)postData,
        dataLen
    );
    if( !res )
    {
        printf("Unable to send request. Error %ld\n", GetLastError());
        exit(1);
    }
    printf("Request sent\n");

//  char *szBuffer = (char*)malloc(sizeof(char)*BUFLEN);
    char szBuffer[BUFLEN];
    DWORD dwRead = 0;

    memset(&szBuffer, '\0', sizeof(szBuffer));

    while( InternetReadFile(hFile, szBuffer, sizeof(szBuffer), &dwRead) && dwRead )
    {
        printf("%s", szBuffer);
    }

    return 0;
}

我能够将数组拆分为变量，但我不确定如何将UserID组合在不同的行中并生成结果？

示例脚本：

{{1}}

使用format operator（-f）构建类似的输出字符串，并使用switch语句来区分这些情况：

$JobType, $data = $line -split ',', 2
switch ($JobType) {
  1 {
    $Username, $UserID = $data -split ','
    '{0} {1} {2}' -f $JobType, $Username, $UserID
  }
  2 {
    $JobID, $UserID, $Action, $Result  = $data -split ',' 
    '{0} {1} {2} {3} {4}' -f $JobType, $JobID, $UserID, $Action, $Result
  }
  default { "Unknown job type: $JobType" }
}

你可以改用它......

$Logs = Get-content logs.txt 

$Type1 = $Logs | ? {$_ -match "^1"}
$Type2 = $Logs | ? {$_ -match "^2"}

$T1Header = "JobType","UserName","UserID"
$T2Header = "JobType","JobID","UserID","Action","Result"

$CSVT1 = ConvertFrom-Csv $Type1 -Delimiter "," -Header $T1Header
$CSVT2 = ConvertFrom-Csv $Type2 -Delimiter "," -Header $T2Header

它将为您创建2个CSV文件，每个文件都带有必需的标题

如果我的问题是正确的，那么您就会问，如何加入logs.txt与相应UserID相对应的不同行。您可以通过构建将用户ID映射到用户名的哈希表来完成此操作：

$Logs = Get-Content .\logs.txt

$userMap = @{}
$jobLog = @()
foreach ($line In $Logs)
{
    if ($line[0] -eq '1')
    {
        $null, $Username, $UserID = $line -split ','
        $userMap[$UserID] = $Username
    }

    elseif ($line[0] -eq '2')
    {
        $jobLog += $line
    }
    # Do whatever is appropriate for logs with different IDs
}

现在，您可以通过替换从剩余的行生成所需的结果。您可能还想使用额外的hastable来替换像'Recv'这样的关键字：

$keywordMap = @{ 
    'Send' = 'send' 
    'Recv' = 'receive'
    'Success' = 'successfully'
    'Fail' = 'failed' 
}
foreach ($line in $jobLog)
{
    $null, $JobID, $UserID, $Action, $Result = $line -split ','
    Write-Output ('Job {0}, {1} {2} {3}' -f $JobID,
        $userMap[$UserID], $keywordMap[$Action], $keywordMap[$Result])
}

如何读取数组并结合唯一ID？
