从VBA访问SurveyMonkey API

我现在才看到这一点-添加评论或回答问题时，StackOverflow是否具有提醒我的功能，所以我知道回头吗？

这是开始代码：

Option Explicit
Public Const gACCESS_TOKEN As String = "xxxxxxxxxxxxxxxxxxxxxx"
Declare Function GetTickCount Lib "kernel32" () As Long
Declare Sub Sleep Lib "kernel32" (ByVal lngMilliSeconds As Long)
' for a JSON parser see https://code.google.com/p/vba-json/

Public Sub test()
Dim vRequestBody  As Variant, sResponse As String, sSurveyID As String
sSurveyID = "1234567890"

vRequestBody = "{""survey_id"":" & """" & sSurveyID & """" _
              & ", ""fields"":[""collector_id"", ""url"", ""open"", ""type"", ""name"", ""date_created"", ""date_modified""]" _
              & "}"
sResponse = SMAPIRequest("get_collector_list", vRequestBody)

End Sub
Function SMAPIRequest(sRequest As String, vRequestBody As Variant) As String
Const SM_API_URI As String = "https://api.surveymonkey.net/v2/surveys/"
Const SM_API_KEY As String = "yyyyyyyyyyyyyyyyyyyyyyyy"
Dim bDone As Boolean, sMsg As String, sUrl As String, oHttp As Object ' object MSXML2.XMLHTTP
Static lsTickCount As Long

If Len(gACCESS_TOKEN) = 0 Then
   Err.Raise 9999, "No Access token"
End If
On Error GoTo OnError

sUrl = SM_API_URI & URLEncode(sRequest) & "?api_key=" & SM_API_KEY
   'Debug.Print Now() & " " & sUrl
Application.StatusBar = Now() & " " & sRequest & " " & Left$(vRequestBody, 127)
Set oHttp = CreateObject("MSXML2.XMLHTTP") ' or "MSXML2.ServerXMLHTTP"

Do While Not bDone ' 4.33 offer retry
   If GetTickCount() - lsTickCount < 1000 Then ' if less than 1 sec since last call, throttle to avoid sResponse = "<h1>Developer Over Qps</h1>"
      Sleep 1000 ' wait 1 second so we don't exceed limit of 2 qps (queries per second)
   End If
   lsTickCount = GetTickCount()
   'Status  Retrieves the HTTP status code of the request.
   'statusText Retrieves the friendly HTTP status of the request.
   'Note   The timeout property has a default value of 0.
   'If the time-out period expires, the responseText property will be null.
   'You should set a time-out value that is slightly longer than the expected response time of the request.
   'The timeout property may be set only in the time interval between a call to the open method and the first call to the send method.
RetryPost:  ' need to do all these to retry, can't just retry .Send apparently
   oHttp.Open "POST", sUrl, False   ' False=not async
   oHttp.setRequestHeader "Authorization", "bearer " & gACCESS_TOKEN
   oHttp.setRequestHeader "Content-Type", "application/json"

   oHttp.send CVar(vRequestBody)     ' request body needs brackets EVEN around Variant type
   '-2146697211   The system cannot locate the resource specified. => no Internet connection
   '-2147024809   The parameter is incorrect.
   'String would return {"status": 3, "errmsg": "No oJson object could be decoded: line 1 column 0 (char 0)"} ??
   'A Workaround would be to use parentheses oHttp.send (str)
   '"GET" err  -2147024891   Access is denied.
   '"POST" Unspecified error = needs URLEncode body? it works with it but

   SMAPIRequest = oHttp.ResponseText
   'Debug.Print Now() & " " & Len(SMAPIRequest) & " bytes returned"
   sMsg = Len(SMAPIRequest) & " bytes returned in " & (GetTickCount() - lsTickCount) / 1000 & " seconds: " & sRequest & " " & Left$(vRequestBody, 127)

   If Len(SMAPIRequest) = 0 Then
      bDone = MsgBox("No data returned - do you wish to retry?" _
            & vbLf & sMsg, vbYesNo, "Retry?") = vbNo
   Else
      bDone = True ' got reply.
   End If
Loop ' Until bdone

   Set oHttp = Nothing
   GoTo ExitProc

OnError:   ' Pass True to ask the user what to do, False to raise to caller
   Select Case MsgBox(Err.Description, vbYesNoCancel, "SMAPIRequest")

Public Function URLEncode(StringVal As String, Optional SpaceAsPlus As Boolean = False) As String

End If
End Function

编辑4月23日添加更多代码。

主题。来自用户表单中的代码。

Set jLib = New JSONLib
vRequestBody = "{"
If Me.txtDaysCreated > "" Then
   vRequestBody = vRequestBody & JKeyValue("start_date", Format$(Now() - CDbl(Me.txtDaysCreated), "yyyy-mm-dd")) & ","
End If
If Me.txtTitleContains > "" Then
' title contains "text", case insensitive
vRequestBody = vRequestBody & JKeyValue("title", Me.txtTitleContains) & ","
End If
vRequestBody = vRequestBody _
   & JKeyValue("fields", Array("title", "date_created", "date_modified", "num_responses", _
      "language_id", "question_count", "preview_url", "analysis_url")) & "}"


'returns in this order: 0=date_modified  1=title  2=num_responses  3=date_created   4=survey_id
' and in date_created descending
sResponse = GetSMAPIResponse("get_survey_list", vRequestBody)

------------------------------------------
Function JKeyValue(sKey As String, vValues As Variant) As String
      Dim jLib As New JSONLib
 JKeyValue = jLib.toString(sKey) & ":" & jLib.toString(vValues)
 Set jLib = Nothing
End Function

编辑VBA代码的4月25日概述以获取数据

SM文档中对此进行了介绍，但我将概述其在VBA中的外观。对get_survey_details的响应将为您提供所有测量设置数据。使用Set oJson = jLib.parse（Replace（sResponse，“ \ r \ n”，“”））获得一个json对象。
设置dictSurvey = oJson（“ data”）
会提供字典，因此您可以获取像dictSurvey（“ num_responses”）之类的数据。我认为您知道如何索引字典对象以获得字段值。

Set collPages = dictSurvey("pages") 

给您页面的集合。未记录的字段“位置”为您提供调查UI中页面的顺序。

For lPage = 1 To collPages.Count
   Set dictPage = collPages(lPage) 
Set collPageQuestions = dictPage("questions") ' gets you the Qs on this page
For lPageQuestion = 1 To collPageQuestions.Count
     Set dictQuestion = collPageQuestions(lPageQuestion) ' gets you one Q
Set collAnswers = dictQuestion("answers") ' gets the QuestionOptions for this Q
        For lAnswer = 1 To collAnswers.Count
           Set dictAnswer = collAnswers(lAnswer) ' gets you one Question Option

等等

然后，根据上面给出的响应数量，一次遍历受访者100-再次查看SM文档，以了解有关如何指定开始和结束日期以随时间进行增量下载的详细信息。从响应到“ get_respondent_list”的响应中创建一个json对象。收集每个响应者的字段并累积最多100个响应者ID的列表。然后为该列表“ get_responses”。

Set collResponsesData = oJson("data")
For lResponse = 1 To collResponsesData.Count

If not IsNull(collResponsesData(lResponse)) then 
... get fields...
Set collQuestionsAnswered = collResponsesData(lResponse)("questions")
  For lQuestion = 1 To collQuestionsAnswered.Count
     Set dictQuestion = collQuestionsAnswered(lQuestion)
        nQuestion_ID = CDbl(dictQuestion("question_id"))
        Set collAnswers = dictQuestion("answers") ' this is a collection of dictionaries
        For lAnswer = 1 To collAnswers.Count

           On Error Resume Next ' only some of these may be present
           nRow = 0: nRow = CDbl(collAnswers(lAnswer)("row"))
           nCol = 0: nCol = CDbl(collAnswers(lAnswer)("col"))
           nCol_choice = 0: nCol_choice = CDbl(collAnswers(lAnswer)("col_choice"))
           sText = "": sText = collAnswers(lAnswer)("text")
           nValue = 0: nValue = Val(sText)  
           On Error GoTo 0

并将所有这些值保存在记录集或工作表或任何有帮助的希望中。
