我们最多使用Java开发,但我们希望使用ms集成测试(使用https://github.com/scottmuc/Pester)我们的Web服务。为此,我正在编写连接到Web服务的powershell脚本,并将响应与我从文件加载的xml进行比较。
[System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
$instance = New-WebServiceProxy -Uri "https://localhost:7002/service?WSDL" -Namespace "myspace"
$instance.Credentials = new-object System.Net.NetworkCredential("user", "pass")
...
$reply = $instance.fetchInformation($inputA, $inputB)
[xml]$expected = Get-Content ("expected.xml")
...
但是,现在我有一个$ reply,其中包含来自myspace命名空间的对象和包含XMLNode的$ expected。我看到两种方法可以做到这一点(可能还有更多):

您可以将Web服务返回的响应序列化为XML,并将其与expected.xml
文件的内容作为字符串进行比较。
以下是一个例子:
$writer = New-Object System.IO.StringWriter
$serializer = New-Object System.Xml.Serialization.XmlSerializer($reply.GetType())
$serializer.Serialize($writer, $reply)
$replyAsXml = $writer.ToString()
$expectedReplyAsXml = Get-Content expected.xml
$replyAsXml -eq $expectedReplyAsXml
请注意,在此示例中,您需要确保expected.xml
文件中包含的XML与XmlSerializer返回的XML在间距和缩进方面的匹配。为了避免这种情况,您可以在比较它们之前从两个字符串中删除所有额外字符(例如空格和换行符)。
答案 1 :(得分:0)
我最终得到了一种完全不同的方法。这两个XML彼此完全不同,所以我创建了一个自定义比较器。这使我可以简单地编写自定义代码来忽略无趣的差异。
这会导致一些原始代码完成这项工作:
# Assume two arrays of equal length
Function Zip {
Param($a1, $a2)
$sum = New-Object object[] $a1.Count
For ($i = 0; $i -lt $a1.Count; ++$i) {
$sum[$i] = New-Object object[] 2
$sum[$i][0] = $a1[$i]
$sum[$i][1] = $a2[$i]
}
Return ,$sum
}
Function XmlChildNodes2List{
param($nodes)
$myArray = New-Object object[] 0
For ($i = 0; $i -lt $nodes.Count; ++$i) {
$node = $nodes.Item($i)
If ($node -ne $null) {
$myArray += $node
}
}
Return ,$myArray
}
Function ShowContext{
Param($ctx)
" at " + $ctx
}
Function CompareNode{
Param($o1, $o2, $ctx)
Try {
Switch ($o1.GetType().Name) {
"XmlDocument" {
CompareXml $o1.ChildNodes $o2.ChildNodes
}
"XmlChildNodes" {
$olist1 = XmlChildNodes2List $o1 | Sort
$olist2 = XmlChildNodes2List $o2 | Sort
If ($olist1.Count -ne $olist2.Count) {
$msg = "Unequal child node count " + ($olist1 -join ",") + " and " + ($olist2 -join ",") + (ShowContext $ctx)
throw $msg
} Else {
$list = Zip $olist1 $olist2
$value = $true
foreach ($item in $list) {
if ($value -eq $true) {
$value = CompareXml $item[0] $item[1] $ctx
}
}
$value
}
}
"XmlElement" {
If ($o1.LocalName -eq $o2.LocalName) {
If ($o1.LocalName -eq "uninterestingElement" -or $o1.LocalName -eq "uninterestingElement2") {
$true
} Else {
CompareXML $o1.ChildNodes $o2.ChildNodes ($ctx + "/" + $o1.LocalName)
}
} Else {
throw ("Element " + $o1.LocalName + " != " + $o2.LocalName + (ShowContext $ctx))
}
}
"XmlDeclaration" {
$true
}
"XmlText" {
$result = $o1.InnerText.Replace("`r`n","`n")
$expect = $o2.InnerText.Replace("`r`n","`n")
# TODO: Hack to remove timezone from expected dates in format 2005-09-01+02:00, the webservice side of the
# reply to xml-conversion looses them
If ($expect -match "^(\d{4}-\d\d-\d\d)\+\d\d:\d\d$") {
$expect = $Matches[1]
}
If ($result -eq $expect) {
$true
} Else {
throw ($o1.InnerText + " is not equal to " + $o2.InnerText + (ShowContext $ctx))
}
}
Default {
throw ("What to do with node " + $o1.GetType().Name + (ShowContext $ctx))
}
}
} Catch [Exception] {
throw $_
}
}
Function CompareXML{
Param($o1, $o2, $ctx)
If ($o1 -eq $null -and $o2 -eq $null) {
$true
} ElseIf ($o1 -eq $null -or $o2 -eq $null) {
throw ("Response or expected is null")
} ElseIf ($o1.GetType() -eq $o2.GetType()) {
CompareNode $o1 $o2 $ctx
} Else {
throw ($o1.GetType().Name + " is not " + $o2.GetType().Name + (ShowContext $ctx))
}
}
然后可以在两个XML上运行:
CompareXML $result $expected ""
