request.GetResponse（）在vb.net中给出了“操作已经超时。” [英] request.GetResponse() has giving “The operation has timed-out.” in vb.net

问题描述

我在vb.net中获取POST方法Web请求的响应时遇到问题，并且GET请求正常工作并获得响应，而相同的请求在C＃中正常工作，其后执行相同的步骤。所以，任何人都可以帮我解决这个问题



这里Url是一个弹性搜索引擎，postData变量中的数据是一个json字符串，响应将是也是一个json字符串



Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create（HOSTIP：9200 / es5078_1 / _search？pretty =真的）



request.Method =POST

Dim postData As String = CGeneral.gstrMsgNC（236）

request.ContentType =application / x-www-form-urlencoded

request.ContentLength = postData.Length

request.Timeout = 100000



Dim writer As StreamWriter = New StreamWriter（request.GetRequestStream（））

writer.Write（postData）

请求。 Expect =

request.AllowAutoRedirect = True

request.AllowWriteStreamBuffering = True



昏暗的响应作为系统.Net.HttpWebResponse = request.GetResponse （）



Dim responseReader As StreamReader = New StreamReader（response.GetResponseStream（））

Dim result As String = responseReader.ReadToEnd（）

I'm facing problem in getting response for a POST method web request in vb.net and the GET request is working properly and getting the response, while the same request is working fine in C# with the same steps followed here. So, can any one help me to try to sort out this

Here Url is a Elastic search engine and the data in postData variable is a json string and the response will also be is a json string

Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("HOSTIP:9200/es5078_1/_search?pretty=true")

request.Method = "POST"
Dim postData As String = CGeneral.gstrMsgNC(236)
request.ContentType = "application/x-www-form-urlencoded"
request.ContentLength = postData.Length
request.Timeout = 100000

Dim writer As StreamWriter = New StreamWriter(request.GetRequestStream())
writer.Write(postData)
request.Expect = ""
request.AllowAutoRedirect = True
request.AllowWriteStreamBuffering = True

Dim response As System.Net.HttpWebResponse = request.GetResponse()

Dim responseReader As StreamReader = New StreamReader(response.GetResponseStream())
Dim result As String = responseReader.ReadToEnd()
