我已经阅读了很多关于 Web 请求超时的帖子（如果不是全部的话），并且提供的解决方案没有奏效。我从 Big Commerce 收到订单，然后更新 Big Commerce 状态代码。我可以更新 2 个订单，然后在第三个订单超时，每次都不管星期几或一天中的时间。

App.Config 文件具有：

```
<system.web>
    <httpruntime executionTimeout="180" />
</system.web>
```

代码：

```
    Try
        Dim strJSON As String = "{""status_id"": 9}"
        Dim postBytes As Byte() = System.Text.Encoding.UTF8.GetBytes(strJSON)
        For i As Integer = 0 To dto.Rows.Count - 1
            strWebOrder = dto.Rows(i).Item("WebOrder")
            Dim strHttp As String = "https://api.bigcommerce.com/stores/storeid/v2/orders/" & strWebOrder
            Dim request As HttpWebRequest = DirectCast(WebRequest.Create(strHttp),HttpWebRequest)
            request.accept = "application/json"
            request.ContentType = "application/json"
            request.Headers("X-Auth-Token") = strauthToken
            request.Timeout = 10000
            request.AllowWriteStreamBuffering = False
            request.SendChunked = True
            request.Method = "PUT"
            Dim postStream As Stream = request.GetRequestStream()
            postStream.Write(postBytes,postBytes.Length)
            Dim response As Httpwebresponse = DirectCast(request.GetResponse(),Httpwebresponse)
            If response.StatusCode = 200 Then
                strErrorRef = "Web " & strWebOrder
                strErrorReason = "Order Status Changed to Exported"
                strPutMessage = ""
                WriteError()
            Else
                strErrorRef = "Web " & strWebOrder
                strErrorReason = "Unable to change Web Order Status to Exported"
                strPutMessage = ""
                WriteError()
            End If
        Next
    Catch ex As Exception
        strErrorRef = "Web " & strWebOrder
        strErrorReason = "Unable to change Web Order Status to Exported"
        strPutMessage = (ex.ToString)
        WriteError()
    End Try
```
