P0ST variables to web server?
- by OverTheRainbow
Hello
I've been trying several things from Google to POST data to a web server, but none of them work: I'm still stuck at how to convert the variables into the request, considering that the second variable is an SQL query so it has spaces.
Does someone know the correct way to use a WebClient to POST data? I'd rather use WebClient because it requires less code than HttpWebRequest/HttpWebResponse.
Here's what I tried so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim wc = New WebClient()
'convert data
wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Dim postData = String.Format("db={0}&query={1}", _
HttpUtility.UrlEncode("books.sqlite"), _
HttpUtility.UrlEncode("SELECT id,title FROM boooks"))
'Dim bytArguments As Byte() = Encoding.ASCII.GetBytes("db=books.sqlite|query=SELECT * FROM books")
'POST query
Dim bytRetData As Byte() = wc.UploadData("http://localhost:9999/get", "POST", postData)
RichTextBox1.Text = Encoding.ASCII.GetString(bytRetData)
Exit Sub
Dim client = New WebClient()
Dim nv As New Collection
nv.Add("db", "books.sqlite")
nv.Add("query", "SELECT id,title FROM books")
Dim address As New Uri("http://localhost:9999/get")
'Dim bytRetData As Byte() = client.UploadValues(address, "POST", nv)
RichTextBox1.Text = Encoding.ASCII.GetString(bytRetData)
Exit Sub
'Dim wc As New WebClient()
'convert data
wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Dim bytArguments As Byte() = Encoding.ASCII.GetBytes("db=books.sqlite|query=SELECT * FROM books")
'POST query
'Dim bytRetData As Byte() = wc.UploadData("http://localhost:9999/get", "POST", bytArguments)
RichTextBox1.Text = Encoding.ASCII.GetString(bytRetData)
Exit Sub
End Sub
Thank you.
