在POST请求VBA Excel中发送数组字符串

Question

Dim lastRow As Variant
lastRow = Range("B" & Rows.Count).End(xlUp).Row

Dim vvArray As Variant
vvArray = Range("B12:B" & lastRow).Value

Dim vvArrayString() As String
ReDim vvArrayString(1 To UBound(vvArray))
For i = 1 To UBound(vvArray)
    vvArrayString(i) = vvArray(i, 1)
Next

Dim TCRequestItem As Object
Set TCRequestItem = CreateObject("WinHttp.WinHttpRequest.5.1")
TCRequestItem.Open "POST", "url", False
TCRequestItem.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
TCRequestItem.send ("keyArray=" + vvArrayString)

Answer 1

我不明白为什么要设置vvarray然后设置vvarrayString？为什么不通过循环B列直接转到vvarrayString呢？

Dim LastRow as Long 
LastRow = Range("B" & Rows.Count).End(xlUp).Row

Dim vvArrayString(1 to LastRow-11)
For i = 12 to LastRow
    vvArrayString(1-11) = Range("B" & i).text
Next

这应该为您正确设置数组，然后您可以继续下一位代码（http请求）。

编辑：http请求也可以使用类似的循环，因为它是一个简单的重复模式。然而，您需要一个单独的变量；

Dim strPostReq as String 'here's your separate variable

For x = 1 to LastRow-11
    'Just add the same pattern to the end of the string each time
    strPostReq = strPostReq & "keyArray[" & x-1 & "]=" & vvArrayString(x) & "&"
Next
'Then remove the last '&' from the string
strPostReq = Left(strPostReq, Len(strPostReq) - 1)
