-- 作者:xubing051018 -- 发布时间:2022/6/13 10:19:00 -- [求助]关于hc.FormData.Add模拟表单的异常 客户端程序代码如下: Dim http,gd As String http = "http://192.168.3.27:10086/clientShipYMCheck.htm" Dim hc As New HttpClient(http) Dim od As String = "2259" hc.FormData.Add("md","LoadPur") hc.FormData.Add("id",od) hc.Timeout = 100 gd = hc.GetData() hc.FormData.Clear hc.FormData.Add("md","LoadTransQty") hc.FormData.Add("id",od) \'hc.Timeout = 100 gd = hc.GetData() 以上代码,如果不执行最后一行,程序运行没有问题, 如果加上执行最后一行,会报错, 错误内容: 基流不可读。 参数名: stream 请教这是什么问题,要怎么修改。 |
