Android Question Posting Json data to Project Oxford

[EdmundHerbert]

H can anyone help me I am trying to do the following:
----------------------------------------------------------------------------------------------------
PUT face/v0/persongroups/1
Content-Type: application/json
Host: api.projectoxford.ai
Content-Length: 129
Ocp-Apim-Subscription-Key: ••••••••••••••••••••••••••••••••

{
"name":"sample_group",
"userData":"user-provided data attached to the person group"
}
----------------------------------------------------------------------------------------------------
This is what they require:

Face API
PersonGroup - Create a PersonGroup
Creates a new person group with a user-specified ID.

A person group is one of the most important parameters for the Identification API. The Identification searches person faces in a specified person group.

Http Method
PUT
Request parameters
personGroupId
Request headers
Content-Type


Ocp-Apim-Subscription-Key
Request body
JSON fields in request body:

name
String
Person group display name. The maximum length is 128.
userData

String

User-provided data attached to the person group. The size limit is 16KB.

---------------------------------------------------------------------------------------------------



My code looks like this:

Sub CreateGroup()

Try


Dim GroupMap As Map
GroupMap.Initialize
GroupMap.Put("name","sample_group")
GroupMap.Put("userData","sample group created")

Dim JSONGenerator As JSONGenerator
JSONGenerator.Initialize(GroupMap)


' JSONGenerator puts GroupMap.Put("userData","sample group created") first

' then GroupMap.Put("name","sample_group") last this is wrong sequence

Dim JSONstring As String
JSONstring = JSONGenerator.ToString

JSONstring = "{ ""name"":""sample_group"",""userData"":""sample group created"" }"

I tried hard coding json string


Dim job2 As HttpJob

job2.Initialize("job2",Me) ' Create Person Group
job2.PostString("https://api.projectoxford.ai/face/v0/persongroups/1",JSONstring)
job2.GetRequest.SetHeader("Content-Type","application/json")
job2.GetRequest.SetHeader("Ocp-Apim-Subscription-Key","xxxxxxxxxxxxxxxxxxxxxxxxxxx")

Catch
ToastMessageShow("Comms with Oxford failed",False)
End Try
End Sub

It does not work am I doing something stupid

Regards

Edmund

Please use [code]code here...[/code] tags when posting code.

The order of fields in a json string is not important.

You are sending a POST request instead of PUT request.

You need to modify HttpJob and add these two methods:

'Sends a PUT request with the given data as the post data.
Public Sub PutString(Link As String, Text As String)
   PutBytes(Link, Text.GetBytes("UTF8"))
End Sub

'Sends a PUT request with the given string as the post data
Public Sub PutBytes(Link As String, Data() As Byte)
   req.InitializePut2(Link, Data)
   CallSubDelayed2(HttpUtils2Service, "SubmitJob", Me)
End Sub

You should then call PutString.
