Was the extra 'c' a test for the observant?

I've been struggling to send this CURL request in VB.NET and hope someone can help..
Here is a link to the documentation of the exact request I'm trying to send.
This is the sample CURL request:
curl -u 'username:token' 'https://api.dev.name.com/v4/domains' -X POST -H 'Content-Type: application/json' --data '{"domain":{"domainName":"example.org"},"purchasePrice":12.99}'
Here is the code that I put together and tested:
Dim uri As New Uri("https://api.dev.name.com/v4/domains")
Dim myUsername As String = txtUsername.Text.Trim & ":" & txtApiKey.Text.Trim
Dim data As String = "{""domain"":{""domainName"":""example.org""},""purchasePrice"":12.99}"
Dim dataByte As Byte()
request = WebRequest.Create(uri)
request.Headers.Add(HttpRequestHeader.Authorization, "Basic " & Convert.ToBase64String(Encoding.UTF8.GetBytes(myUsername)))
request.ContentType = "application/json"
request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36"
request.Method = "POST"
dataByte = Encoding.UTF8.GetBytes(data)
request.GetRequestStream.Write(dataByte, 0, dataByte.Length)
Dim myResp As HttpWebResponse
myResp = request.GetResponse()
Dim myreader As New System.IO.StreamReader(myResp.GetResponseStream)
WebResponse = myreader.ReadToEnd()
MsgBox(WebResponse)
However, the code above always returns a (400) Bad Request.
Here is another variation of pretty much the same code which I tried:
Dim myReq As HttpWebRequest
Dim myResp As HttpWebResponse
Dim myUsername As String = "username:token"
myReq = HttpWebRequest.Create("https://api.dev.name.com/v4/domains")
myReq.Method = "POST"
myReq.ContentType = "application/json"
myReq.Headers.Add("Authorization", "Basic " & Convert.ToBase64String(Encoding.UTF8.GetBytes(myUsername)))
Dim myData As String = "{""domain"":{""domainName"":""example.org""},""purchasePrice"":12.99}"
Dim dataBytes As Byte() = Encoding.UTF8.GetBytes(myData)
myReq.GetRequestStream.Write(dataBytes, 0, dataBytes.Length)
myResp = myReq.GetResponse()
Dim myreader As New System.IO.StreamReader(myResp.GetResponseStream)
WebResponse = myreader.ReadToEnd()
MsgBox(WebResponse)
But, as you can already guess, it also returns a 400 (Bad Request).

In your CURL command, you are using the '-u' option to provide the username and token as a basic authentication header. In your VB.NET code, you're attempting to encode the credentials manually. Make sure that 'myUsername' has the correct username and token values, and try using the Credentials property of the 'WebRequest' object instead of manually adding the header -
request.Credentials = New NetworkCredential(txtUsername.Text.Trim, txtApiKey.Text.Trim)
The JSON data you're sending in the CURL command needs to be properly serialized before sending it, we use Newtonsoft.Json, not sure if it will help in your situation, if so you can use it where you create an anonymous type to represent the JSON structure and then serializes it using 'JsonConvert.SerializeObject()' -
Imports Newtonsoft.Json
Dim domainData As New With {
.domain = New With {
.domainName = "example.org"
},
.purchasePrice = 12.99
}
Dim data As String = JsonConvert.SerializeObject(domainData)
You need to close the request stream before sending the request -
request.GetRequestStream.Close()
Instead of directly displaying returned responses in a message box, you can return the status codes and any error messages further by using -
Dim statusCode As Integer = CType(myResp, HttpWebResponse).StatusCode
Dim responseText As String = String.Empty
If statusCode = HttpStatusCode.OK Then
Dim myreader As New System.IO.StreamReader(myResp.GetResponseStream)
responseText = myreader.ReadToEnd()
End If
MsgBox(responseText)
I hope any of these suggestions help.

Hey Andre,
Thanks so much for your detailed reply and explanation! I imported Newtonsoft.json no problem and tried implementing your changes. On a positive note, I'm no longer getting a (400) Bad Request reply. However, I'm now getting a (401) Unauthorized response. I've double checked my login details and made sure they were correct. I also tried testing in both the OTE (operational test environment) and the LIVE environment because the details are slightly different for each, but received the same error on both.
Could this be due to how the credentials are now being passed?
Also, if I close "GetRequestStream" before sending the request then I get a message the connection was suddenly terminated when trying to send the request. However, if I put it directly after writing to the stream that issue goes away. Here is a look at my updated code:
Dim uri As New Uri("https://api.dev.name.com/v4/domains")
Dim domainData As New With {
.domain = New With {
.domainName = "example.org"
},
.purchasePrice = 12.99
}
Dim data As String = JsonConvert.SerializeObject(domainData)
Dim dataByte As Byte()
request = WebRequest.Create(uri)
request.Credentials = New NetworkCredential(txtUsername.Text.Trim, txtApiKey.Text.Trim)
request.ContentType = "application/json"
request.Method = "POST"
dataByte = Encoding.UTF8.GetBytes(data)
request.GetRequestStream.Write(dataByte, 0, dataByte.Length)
request.GetRequestStream.Close()
Dim myResp As HttpWebResponse
myResp = request.GetResponse()
Dim statusCode As Integer = CType(myResp, HttpWebResponse).StatusCode
Dim responseText As String = String.Empty
If statusCode = HttpStatusCode.OK Then
Dim myreader As New System.IO.StreamReader(myResp.GetResponseStream)
responseText = myreader.ReadToEnd()
End If
MsgBox(responseText)
Any suggestions? Thanks again!

Closing the stream - my bad, I added it prematurely.  Please disregard my suggestion to close the request stream before sending the request or add it after the stream were read.
(401) Unauthorized response, it seems that your server did not accept the given credentials as valid. - There are a few things you can try.
Make sure that the API you are accessing is expecting basic authentication and that the credentials should be provided in the Authorization header. If the API expects a different authentication method, such as API keys or OAuth, you will need to adjust your authentication to accept the request as per their requirements.
Check that the API endpoint you are using (https://api.dev.name.com/v4/domains) is 100% correct.
To isolate or debug the issue, you could try using a different client, such as cURL or Postman, with the same credentials and endpoint. This might help determine if the problem lies with the code or if there might be an issue with the credentials or API itself.
Check your API documentation to make sure that you are following the correct authentication process and that there are no additional steps required.
Hope this points you in the right direction.

i understand the code by i do not see where to change the sound source for ex. to line in...
they say this
Notes : A record class, which when turned
' : into an object lets you record sound
' : through mic, cd-line, etc... into a file

Try asking Suresh Sutha, it's his/her code.
|
|
|
|
|
Probably deprecated...i will try NAudio...is it good alternative?
|
|
|
|

according to the code...may i add more of these (24-bits)
lSamples = 32000 : lBits = 16 : lChannels = 2
ElseIf _SoundFormat = SoundFormats.Stereo_176kbps_16_Bit Then
lSamples = 44100 : lBits = 16 : lChannels = 2
ElseIf _SoundFormat = SoundFormats.Stereo_192kbps_16_Bit Then
lSamples = 48000 : lBits = 16 : lChannels = 2
End If
i would like to have
ElseIf _SoundFormat = SoundFormats.Stereo_192kbps_24_Bit Then
lSamples = 48000 : lBits = 24 : lChannels = 2

Sorry, no idea. As I said you need to talk to the person who wrote the code.
|
|
|
|
|
Ok thanks ...i will try..i just would like to know how to select the input source device...i think is just what misses in my new project....now im trying to make a sound recording..but i would like to record mic,line in and if possible desktop sounds..
|
|
|
|
|
I took also a look onto the Code and I can't aslo not find a Property like requested by you.
For me the posted Code is incomplete and also not able to make any recording.
So you really have to ask the person who has written this code for a complete Code ... or you should look anywhere else for Code which matches to your requirement ...

hey guys...can anyone tell me how to chnage the highlight color for my listbox?
i tried some google snippets but no luck...
Thanks!!
|
|
|
|
|

hi..yes im using this code:
<pre> Private Sub ListBox1_DrawItem(sender As Object, e As DrawItemEventArgs) Handles ListBox1.DrawItem
If ListBox1.SelectedItem <> "" Then
e.DrawBackground()
If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
e.Graphics.FillRectangle(Brushes.Red, e.Bounds)
End If
Using b As New SolidBrush(e.ForeColor)
e.Graphics.DrawString(ListBox1.GetItemText(ListBox1.Items(e.Index)), e.Font, b, e.Bounds)
End Using
e.DrawFocusRectangle()
End If
End Sub
but it seems that the items text are not appearing in the right color..only when i click them...
this is hard to explain...
|
|
|
|
|
I have just tried it with the MSDN code in the link I gave you and it seems to work - with one correction. The following block:
If ((e.State And DrawItemState.Selected) = DrawItemState.Selected) Then
e.Graphics.FillRectangle(Brushes.CornflowerBlue, e.Bounds)
Else
is missing the parentheses around e.State And DrawItemState.Selected.

i changed the color to white and it shows only white rectangles but no text!!!..i wish i can put an image or video..sometimes one image worths more than a thousand words!!
|
|
|
|
|
OK..i went a bit foward..it is formating but when i load my files they do not appear in the listbox..i have to click the listbox to show the files loaded..
|
|
|
|
|
When i load the files into the listbox nothing shows but if i click where the items should be they appear with the formated style
|
|
|
|
|
i think is because im starting with an empty listbox...as i said...when i load the files they do not show..but..if i click where they were supposed to be they show with the different highlight color (red for ex)...

I took some of the code from the link to the MSDN documentation that I provided in an earlier message. The basic idea is that it gets a list of filenames and populates the ListBox with them. You can then test the selection of individual items, and how to process the resulting set.
