I have an access database which I'm using to create a json POST API to a website utilising Neto (https://developers.neto.com.au/documentation/engineers/api-documentation). I am new to APIs, but have been researching for several months and making progress in understanding how it works. I have managed to get a 200 status response from the request which would indicate the header info (including authentication is correct) but error in relation to the body (I believe).
Code as per below:
Dim reader As New XMLHTTP60
Dim username As String, APIkey As String
Dim strJson As String
strJson = "{" & _
"'Filter': {" & _
"'OrderStatus': 'Pick'," & _
"'OutputSelector': [" & _
"'OrderID'," & _
"'ShippingOption'," & _
"]," & _
"}" & _
"}"
username = "xxx"
APIkey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
reader.Open "POST", "https://www.yoursite.co.nz/do/WS/NetoAPI", False
reader.setRequestHeader "NETOAPI_USERNAME", username
reader.setRequestHeader "NETOAPI_KEY", APIkey
reader.setRequestHeader "Content-Type", "application/json"
reader.setRequestHeader "Accept", "application/json"
reader.setRequestHeader "NETOAPI_ACTION", "GetOrder"
reader.send strJson
Debug.Print reader.Status
Debug.Print reader.responseText
error message:
{"CurrentTime":"2021-09-17 02:42:50","Ack":"Error","Messages":[{"Error":{"Message":"JSON Error","SeverityCode":"Error"},"Warning":{"Message":"Warning","SeverityCode":"Warning","Description":"'\"' expected, at character offset 1 (before \"'Filter': {'OrderSta...\")"}}]}
Initially i am just trying to retrieve 2 pieces of data (OrderID and ShippingOption) for any orders with status of Pick.
i have tried replacing all ' with "" as i've seen in other posts along with a few other variations but with no luck.
Any help would be appreciated. Thanks
You are using single quote instead of double quotes in your JSON
The value of Filter is a collection enclosed with [ ] so I believe you need to wrap Pick as well (despite there's only 1 value).
You have an extra , after ShippingOption when it's the last value so remove that.
Try this instead:
strJSON = "{" & _
"""Filter"": {" & _
"""OrderStatus"": [""Pick""]," & _
"""OutputSelector"": [" & _
"""OrderID""," & _
"""ShippingOption""" & _
"]" & _
"}" & _
"}"
Above will produce the JSON below:
{"Filter": {"OrderStatus": ["Pick"],"OutputSelector": ["OrderID","ShippingOption"]}}
I'm trying to change my application so that it outputs JSON instead of HTML when it makes an AJAX request for some data. I have an ADODB RecordSet. I need to loop through it row-by-row and add/change/remove different values. Then I need to take all the modified rows and response.write them as JSON. I'm using JSON2.asp so my application already supports JSON.parse & JSON.stringify but I can't get it to spit out the multi-dimensional array as JSON.
set rs = conn.execute(strQuery)
if Not rs.EOF Then
rsArray = rs.GetRows() 'This pulls in all the results of the RecordSet as a 2-dimensional array
columnCount = ubound(rsArray,1)
rowCount = ubound(rsArray,2)
For rowIndex = 0 to rowCount 'Loop through rows as the outer loop
rsArray(3,0) = "somethingelse"
Next 'Move on to next row if there is one
response.write JSON.stringify(rsArray) & " _______ "
End If
I just need to be able to go through the results of my database query, modify the results, and then output the modified results in JSON format. What's the right way to do this?
The JSON2.asp implementation doesn't have a "Load From Database" function which means you will have to implement something to convert the ADODB.Recordset to a JSON structure yourself.
If you are willing to use a different script there is an implementation by RCDMK on GitHub that does have a LoadRecordset() method, it's called JSON object class 3.5.3.
This makes loading data from an ADODB.Recordset really straightforward.
<!-- #include virtual="/jsonObject.class.asp" -->
<%
Response.LCID = 2057
'...
Dim rs: Set rs = conn.execute(strQuery)
Dim JSON: Set JSON = New JSONobject
Call JSON.LoadRecordset(rs)
Call Response.Clear()
Response.ContentType = "application/json"
Call JSON.Write()
%>
Code has been tested using a disconnected recordset, the ... here denote assumed code to setup your recordset, connection etc
It's worth noting you could write this yourself, it's not a huge leap to loop through an ADODB.Recordset and build a JSON string. However, I would argue against for a few reasons;
It is a time-consuming exercise.
Very easy to miss something (like checking for numeric data types, when generating output).
Depending on how it is coded can make it awkward to maintain (For example, if not injecting property names directly from the recordset and choosing to "hardcode" them instead).
Why reinvent the wheel ? There are a lot of public implementations in the wild that deal with the issues raised here. Admittedly, some are better than others, but it takes five minutes to include them and give it a try.
Just for completeness here is my local test code using a disconnected recordset
<!-- #include virtual="/jsonObject.class.asp" -->
<%
Call init()
Sub init()
Dim fields: fields = Array(Array("title", adVarChar, 50), Array("firstname", adVarChar, 50), Array("lastname", adVarChar, 50), Array("age", adInteger, 4))
Dim rs: Set rs = Server.CreateObject("ADODB.Recordset")
Call InsertRow(rs, fields, Array("Mr", "Joe", "Bloggs", 31))
Call InsertRow(rs, fields, Array("Mr", "John", "Smith", 42))
Response.LCID = 2057
Dim JSON: Set JSON = New JSONobject
Call JSON.LoadRecordset(rs)
Call Response.Clear()
Response.ContentType = "application/json"
Call JSON.Write()
End Sub
Sub InsertRow(ByVal rs, fields, values)
With rs
If rs.State <> adStateOpen Then
For Each fld In fields
Call .Fields.Append(fld(0), fld(1), fld(2))
Next
.CursorLocation = adUseClient
.CursorType = adOpenDynamic
Call .Open()
End If
Call .AddNew()
For i = 0 To UBound(fields, 1)
.Fields(fields(i)(0)).Value = values(i)
Next
Call .Update()
Call .MoveFirst()
End With
End Sub
%>
Output:
{"data":[{"title":"Mr","firstname":"Joe","lastname":"Bloggs","age":31},{"title":"Mr","firstname":"John","lastname":"Smith","age":42}]}
Here ya go. This works for me.
set rs = conn.execute(strQuery)
c=0
Response.write "["
Do Until rs.eof
'Assign variables here with whatever you need to change
title = rs(0)
fName = rs(1)
lName = rs(2)
empID = rs(3)
With Response
if c > 0 then .write ", "
.write "{" & chr(34) & "Title" & chr(34) & " : " & chr(34) & title & chr(34) & ", " & chr(34) & "FirstName" & chr(34) & " : " & chr(34) & fName & chr(34) & ", "
.write chr(34) & "LastName" & chr(34) & " : " & chr(34) & lName & chr(34) & ", " & chr(34) & "EmpID" & chr(34) & " : " & chr(34) & empID & chr(34) & "}"
End With
c = c + 1
rs.MoveNext
Loop
Response.write "]"
This will write your JSON object directly to the page.
try setting content-type to "application/json" on top of your asp page.

I am able to use the parser to return "status", "responseTime" and "message". Anything beyond that (the opening of the second curly bracket) I get nothing.
Below is the code I am trying to use:
Dim p As Object
Set p = JSON.parse(gbl_response)
'Print the text of a nested property '
Debug.Print p.Item("responseTime")
'Print the text of a property within an array '
Debug.Print p.Item("Results").Item("series").Item("seriesID")
The print of p.Item("responseTime") works and returns "71", however I get an "invalid call procedure or argument" error on the second print attempt.
For the life of me, I've searched around and have not found any solutions. I've tried this which seemed almost identical, but alas, I've tried to replicate the solution here and it seems to have not worked.
Thank you for you assistance!

The very last line of code causes this error
ADODB.Recordset error '800a0cc1'
Item cannot be found in the collection corresponding to the requested name or ordinal.
FilePath, line 244
Line 244 is the very last line of code that should write Some information about each seminar on the webpage.
I'm pretty sure at this point I am pointing to an incorrect file path because I have an extra space somewhere in all the different string.
My question now is Would the ones in the very beginning, meaning the ones used in
"<p style=" & "margin-left:10px;" & "><img src=" & "./img/right_arrowblue.png"
be causing the trouble.
I'm also unfamiliar with using the "Expand/collapse" so if someone could tell me a little more about that. I am trying to fix someone elses code so I am a little behind the 8 ball.
One small step to a solution:
Your SQL
"SELECT * FROM Seminars WHERE [SeminarID] = 5 ORDER BY DESC"
is definitely wrong: ORDER BY needs (at least) a column name: ORDER BY [SeminarID] DESC.
If that does not solve all your problems, we'll have to think about a step by step approach.
If you get errors, tell us about them (number, description, line). That's what I meant, when I ask you to publish them. If you can't better info than "There was an error when processing the URL" from IIS, then you have to write some command line script to get the database related code absolutely right.
Start with experiments.vbs:
Dim sCS : sCS = !your connection string!
Dim oCN : Set oCN = CreateObject("ADODB.Connection")
oCN.Open sCS
WScript.Echo "CN open:", oCN.State
Dim sSQL : sSQL = !your SQL statement!
Dim oRS : Set oRS = oCN.Execute(sSQL)
WScript.Echo "RS EOF:", CStr(oRS.EOF)
WScript.Echo "Frs Col:", oRS.Fields(0).Name, oRS.Fields(0).Type
Dim i : i = 0
Do Until oRS.EOF
WScript.Echo i, oRS.Fields(0).Value
i = i + 1
oRS.MoveNext
Loop
oCN.Close
and run it in a command window (DOS box): cscript experiments.vbs. This should get you either some lines like:
CN open: 1
RS EOF: False
Frs Col: Id 3
0 ...
1 ...
2 ...
or a focused/publishable error message like:
... .vbs(2465, 14) Microsoft OLE DB Provider for SQL Server: Falsche Syntax in der Nä
he des 'DESC'-Schlüsselworts.
(bad syntax near DESC), which got when I tried the statement
"SELECT * FROM Alpha ORDER BY DESC"
RS.MoveNext
Put the above code on the line before the Loop keyword to avoid an infinite loop.
Are you missing the loop keyword at the end of your loop block?
