Powershell 获取不生成调用restmethod可以处理的数组的内容

作为后续操作，我不想在脚本中使用长数组，而是想从文本文件中绘制。所以我替换了这个：

$URL=''，''

用这个

$URL=获取内容。/urlfile.txt

或者（就我所知功能相同）这个

$URL=@（获取内容。/urlfile.txt）

但我最终得到了调用RestMethod的结果：远程服务器返回了一个错误：（400）错误请求。

结合我最后一个问题的精彩回答，我的foreach循环如下所示：

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL","EXECUTABLE","THREAT_ENTRY_TYPE_UNSPECIFIED"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $Result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS
    if ( ([string]::IsNullOrEmpty($Result)) ) {} else {write-host $URL "ALERT: Safe browsing match!"}
}

foreach($url in $urls){

    $result = Invoke-RestMethod -Uri $url 
    #do something with $result
}

http://google.com
http://small.com
https://fast.com/

$URLs = get-content .\urls.txt
$HEADERS = @{ 'Content-Type' = "application/json" }
$GOOGLE_API_KEY='[API Key]'
$Uri = 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key='+ $GOOGLE_API_KEY

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS

    [pscustomObject]@{SiteName=$url;ThreatInfo=$result.Matches}
}

。。。但是，如果我使用Get-Content cmdlet创建数组，这将不起作用。如果以任何一种方式运行脚本，然后键入$URL，则返回的数据完全相同。获取内容有什么不对？

使用

Invoke-RestMethod

cmdlet一次只能发出一个

Rest

请求，无法获取数组

您需要添加一个

forEach

循环，一次一个地单步遍历

$URL

，如下所示：

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL","EXECUTABLE","THREAT_ENTRY_TYPE_UNSPECIFIED"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $Result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS
    if ( ([string]::IsNullOrEmpty($Result)) ) {} else {write-host $URL "ALERT: Safe browsing match!"}
}

foreach($url in $urls){

    $result = Invoke-RestMethod -Uri $url 
    #do something with $result
}

http://google.com
http://small.com
https://fast.com/

$URLs = get-content .\urls.txt
$HEADERS = @{ 'Content-Type' = "application/json" }
$GOOGLE_API_KEY='[API Key]'
$Uri = 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key='+ $GOOGLE_API_KEY

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS

    [pscustomObject]@{SiteName=$url;ThreatInfo=$result.Matches}
}

因此，要集成到上一个问题的示例中，您应该有一个

urls.txt

文件，如下所示：

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL","EXECUTABLE","THREAT_ENTRY_TYPE_UNSPECIFIED"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $Result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS
    if ( ([string]::IsNullOrEmpty($Result)) ) {} else {write-host $URL "ALERT: Safe browsing match!"}
}

foreach($url in $urls){

    $result = Invoke-RestMethod -Uri $url 
    #do something with $result
}

http://google.com
http://small.com
https://fast.com/

$URLs = get-content .\urls.txt
$HEADERS = @{ 'Content-Type' = "application/json" }
$GOOGLE_API_KEY='[API Key]'
$Uri = 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key='+ $GOOGLE_API_KEY

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS

    [pscustomObject]@{SiteName=$url;ThreatInfo=$result.Matches}
}

然后您的代码将如下所示：

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL","EXECUTABLE","THREAT_ENTRY_TYPE_UNSPECIFIED"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $Result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS
    if ( ([string]::IsNullOrEmpty($Result)) ) {} else {write-host $URL "ALERT: Safe browsing match!"}
}

foreach($url in $urls){

    $result = Invoke-RestMethod -Uri $url 
    #do something with $result
}

http://google.com
http://small.com
https://fast.com/

$URLs = get-content .\urls.txt
$HEADERS = @{ 'Content-Type' = "application/json" }
$GOOGLE_API_KEY='[API Key]'
$Uri = 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key='+ $GOOGLE_API_KEY

foreach($URL in $URLs) {
    $BODY = @([pscustomobject]@{"client" = @{"clientId" = "company"; "clientVersion" = "1.0"}; "threatInfo" = @{"threatTypes" = "MALWARE","SOCIAL_ENGINEERING","THREAT_TYPE_UNSPECIFIED","UNWANTED_SOFTWARE","POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL"; "threatEntries" = @{"url" = $URL}}})
    $JSONBODY = $BODY | ConvertTo-Json
    $result = Invoke-RestMethod -Method 'POST' -Uri $Uri -Body $JSONBODY -Headers $HEADERS

    [pscustomObject]@{SiteName=$url;ThreatInfo=$result.Matches}
}

这将从文本文件中加载

$URL

列表，然后对每个URL运行Rest请求，并将结果存储在

$result

中。最后，它将使用站点名称创建一个新的PowerShell对象，并向您显示是否存在来自的任何匹配项

您需要以交互方式运行该命令，并查看

$result

中哪些属性对您有意义，但您可以在Google API文档中看到所有预期属性

编辑

找到了bug。当我们使用

Get Content

时，返回的对象保留了原始文件中的一些文档格式信息！我们可以通过检查

$JSONBODY

看到这一点。我们还看到，从

[PSCustomObject

到

Json

的转换也留下了很多污点

要解决这个问题，我们应该使用

ToString（）

方法将

$URL

转换成一个字符串，并且也要放弃转换为

[psCustomObject]

，如下所示

$BODY = @{
        "client" = @{
            "clientId" = "company"; "clientVersion" = "1.0"
            }; 
            "threatInfo" = @{
                "threatTypes" = "MALWARE",
                "SOCIAL_ENGINEERING",
                "THREAT_TYPE_UNSPECIFIED",
                "UNWANTED_SOFTWARE",
                "POTENTIALLY_HARMFUL_APPLICATION"; "platformTypes" = "ANY_PLATFORM"; "threatEntryTypes" = "URL"; "threatEntries" = @{
                    "url" = $URL.ToString()
                }
            }
        }
$JSONBODY = $BODY | ConvertTo-Json

很抱歉，我应该清楚我使用的是foreach循环，我编辑了原始问题以反映这一点。检查您的URL.txt文件是否与我刚才编辑的文件有很大不同。
