请求将指定Python HTTP请求代码转换为VB.NET（UiPath社区版环境）

Got it, let's turn that Python code into VB.NET that works smoothly in UiPath! Here's the full implementation building on the partial code you already have:

Imports System.Text
Imports System.Net.Http
Imports System.Text.Json

' Add this within your UiPath workflow's code activity
Dim payload2 As New Dictionary(Of String, String) From {
    {"auth_token", "YOUR_AUTH_TOKEN"},
    {"status", "green"},
    {"data-title1", "index"},
    {"data-title2", "machine1"},
    {"data-title3", "package10"},
    {"data-title4", "current"},
    {"data-title5", "tmp"}
}

' Serialize the dictionary to a JSON string (matches Python's json.dumps)
Dim jsonPayload As String = JsonSerializer.Serialize(payload2)
Dim requestContent As New StringContent(jsonPayload, Encoding.UTF8, "application/json")

' Use HttpClient to send the POST request
Using client As New HttpClient()
    ' Send the request and get the response (synchronous call for UiPath simplicity)
    Dim response As HttpResponseMessage = client.PostAsync("http://localhost:3030/widgets/hot21", requestContent).Result
    
    ' Optional: Handle the response if needed
    ' Dim responseText As String = response.Content.ReadAsStringAsync().Result
    ' Check if the request succeeded
    If response.IsSuccessStatusCode Then
        ' Add your success logic here (e.g., log a message)
    Else
        ' Add error handling here (e.g., log the status code)
    End If
End Using

Key Notes for UiPath: #

• Namespace References: Make sure your UiPath project has access to System.Net.Http and System.Text.Json (these are usually included by default in newer UiPath versions).
• Alternative Serialization: If you prefer using Newtonsoft.Json (Json.NET) instead, replace the serialization line with:

  Dim jsonPayload As String = Newtonsoft.Json.JsonConvert.SerializeObject(payload2)
  

  You'll need to install the Newtonsoft.Json package via UiPath's Manage Packages first.
• HttpClient Best Practice: Using a Using block ensures the client is properly disposed of, which avoids resource leaks. In UiPath, you could also reuse a single HttpClient instance across your workflow for better performance.
