VB6 Postman 接口测试工具：开启接口自动化之旅

引言

在现代软件开发中，接口测试对于确保应用程序质量至关重要。作为 VB6 开发人员，您可能会寻找一种兼容的工具来满足您的接口测试需求。VB6 Postman 接口测试工具 应运而生，为 VB6 开发人员提供了一个强大且易用的接口测试解决方案。

获取时间戳

时间戳是接口测试中的常见要求，VB6 Postman 接口测试工具提供了一个方便的函数来获取当前时间戳：

Private Declare Function GetTickCount Lib "kernel32" Alias "GetTickCount" () As Long

Function GetTimeStamp() As Long
  GetTimeStamp = GetTickCount()
End Function

MD5 加密验签

MD5 加密算法广泛用于接口安全验证，VB6 Postman 接口测试工具提供了以下函数进行 MD5 加密：

Private Declare Function MD5Checksum Lib "msvcrt.dll" (ByRef sText As String, _
    iTextLength As Long, ByRef sDigest As String) As Long

Function MD5Encrypt(sText As String) As String
  Dim sDigest As String
  Dim iDigestLength As Long

  iDigestLength = 33  ' MD5 encryption result length

  sDigest = Space(iDigestLength)
  MD5Checksum sText, Len(sText), sDigest

  MD5Encrypt = sDigest
End Function

提交 Ajax 请求并解析服务器返回结果

Ajax 请求在现代 Web 开发中非常流行，VB6 Postman 接口测试工具支持提交 Ajax 请求并解析服务器返回结果：

Private Const HTTP_POST As Long = 0
Private Const HTTP_GET As Long = 1

Function HttpRequest(sURL As String, sRequestData As String, _
    iRequestMethod As Long) As String

  Dim hRequest As Long
  Dim sPostData As String

  sPostData = "POST " & sURL & " HTTP/1.0" & vbCrLf & _
    "Content-Type: application/x-www-form-urlencoded" & vbCrLf & _
    "User-Agent: VB6 PostMan" & vbCrLf & vbCrLf & sRequestData

  hRequest = InternetOpen("", INTERNET_OPEN_TYPE_DIRECT, "", "", 0)
  If hRequest Then
    Dim hFile As Long
    hFile = InternetConnect(hRequest, "test.com", 80, 0, 0, INTERNET_SERVICE_HTTP, 0, 0)
    If hFile Then
      Dim dwFlagsAsLong, nBytesAsLong
      dwFlagsAsLong = INTERNET_FLAG_EXISTING_CONNECT
      If InternetWriteFile(hFile, sPostData, Len(sPostData), nBytesAsLong) Then
        Dim sBuffer As String
        Dim dwBytesAvailableAsLong
        Do
          InternetQueryDataAvailable(hFile, dwBytesAvailableAsLong, 0)
          If dwBytesAvailableAsLong Then
            sBuffer = sBuffer & Mid(InternetReadFile(hFile, _
              dwBytesAvailableAsLong), 1, dwBytesAvailableAsLong)
          Else
            Exit Do
          End If
        Loop
      End If
      InternetCloseHandle hFile
    End If
    InternetCloseHandle hRequest
  End If

  HttpRequest = sBuffer
End Function
