正在尝试将数据从parsehub api获取到vb.net

Question

我试图通过使用parsehub api (https://www.parsehub.com/docs/ref/api/v2/?python#get-a-project)将json从web导入到我的vb.net中来抓取数据

我非常熟悉vb.net，但是在文档部分给出的所有示例都是用curl、python、ruby或php编写的。

curl中的api代码为：

curl "https://www.parsehub.com/api/v2/projects/{PROJECT_TOKEN}/run"   -X POST \ 
  -d api_key=tElpQTK_W2mrPKYPl1gug0RE \ 
  -d start_url=http%3A%2F%2Fwww.example.com \ 
  -d start_template=main_template \ 
  -d start_value_override=%7B%22query%22%3A+%22San+Francisco%22%7D \ 
  -d send_email=1
{
  "project_token": "t-0WMEZ-Bc9sWGHAMsYvP7y4", 
  "run_token": "tCcB4hfFP6wvBRe2gwZv9aJp", 
  "status": "initialized", 
  "data_ready": false, 
  "start_time": "2015-02-03T23:09:38", 
  "end_time": null, 
  "pages": 0, 
  "md5sum": null, 
  "start_url": "http://www.example.com", 
  "start_template": "main_template", 
  "start_value": "{\"query\": \"San Francisco\"}"
}

到目前为止，我已经在vb.net中尝试过这样做

    Private Sub Button2_Click_1(sender As Object, e As EventArgs) Handles Button2.Click


  dgv2.Rows.Clear()
            Dim uri As Uri = New Uri("https://www.parsehub.com/api/v2/projects/{PROJECT_TOKEN}/run")
            Dim wc1 As System.Net.WebClient = New System.Net.WebClient()
            Dim VCItem As String = wc1.DownloadString(uri)
            Dim o As JObject = JObject.Parse(VCItem)
            Dim results As List(Of JToken) = o.Children().ToList


            'Try
            For Each item As JProperty In results
                    item.CreateReader()
                    If item.Value.Type = JTokenType.Array Then
                        For Each subitem As JObject In item.Values



                        dgv2.Rows.Add(subitem("leftlabelcells_value"), (subitem("hideextra_number")), (subitem("rightpositioncells_number")))


                    Next
                    End If

但是我得到了一个禁止的错误，它不工作。任何帮助都将非常感谢，并坚持使用这个代码很长时间，我不知道该怎么做。

谢谢。

您希望将调用中的{PROJECT_TOKEN}替换为项目中的实际令牌，您可以在编辑项目时在设置选项卡中找到该令牌。

希望这能有所帮助。将来，你可以随时给我们发邮件到parsehub.com的support，这样你就会得到更快的回复。
