当我尝试从特定股票中检索报价时,来自Yahoo的URL不起作用。关于它的讨论有很多,但是,关于VBA宏似乎什么也没显示
Sub Get_Data()
Dim URL As String
Dim Ticker As String
Dim http As New WinHttpRequest
Dim sCotes As String
Dim Lignes
Dim Valeurs
Dim i As Long
Dim j As Long
Dim sLigne As String
Dim sValeur As String
Ticker = Range("Ticker")
URL = "https://query1.finance.yahoo.com/v7/finance/download/TECK?period1=1540456339&period2=1571992339&interval=1d&events=history&crumb=kjOZLFv6ch2"
http.Send
sCotes = http.ResponseText
MsgBox sCotes
Lignes = Split(sCotes, Chr(10))
For i = 1 To UBound(Lignes) 'until the end of the Lignes variable
sLigne = Lignes(i)
Valeurs = Split(sLigne, ",")
For j = 0 To UBound(Valeurs) - 1
Select Case j
Case 0
sValeur = DateSerial(CLng(Left(Valeurs(0), 4)), CLng(Mid(Valeurs(0), 6, 2)), CLng(Right(Valeurs(0), 2)))
Case 5
sValeur = CLng(Valeurs(5))
Case Else
sValeur = CDbl(Replace(Valeurs(j), ".", ","))
End Select
Range("A1").Offset(i, j) = sValeur
Application.StatusBar = Format(Cells(i, 1), "Short Date")
Next
Next
Application.StatusBar = False
End Sub
在步骤Http.send上的执行错误:“只有在调用Open方法之后才能调用此方法”
尝试替换此代码
URL = "https://query1.finance.yahoo.com/v7/finance/download/TECK?period1=1540456339&period2=1571992339&interval=1d&events=history&crumb=kjOZLFv6ch2"
http.Send
使用此代码:
set http = Server.Createobject("MSXML2.ServerXMLHTTP.6.0")
URL = "https://query1.finance.yahoo.com/v7/finance/download/TECK?period1=1540456339&period2=1571992339&interval=1d&events=history&crumb=kjOZLFv6ch2"
http.open "POST", URL, False
http.Send
错误非常清楚:您需要在open
方法之前调用Send
方法。同样,这将是一个POST请求。您可能还需要将这两行放在[[after open
方法中:
http.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
http.setRequestHeader "Content-Length", 0
.Send()
方法只是发送一个完全空的Dim http As New WinHttpRequest
对象。为了使代码正常工作,请从重复的问题中复制示例并打印http.ResponseText
:
Sub TestMe()
Dim http As Object
Dim url As String
Set http = CreateObject("MSXML2.ServerXMLHTTP.6.0")
url = "https://query1.finance.yahoo.com/v7/finance/download/TECK?period1=1540456339&period2=1571992339&interval=1d&events=history&crumb=kjOZLFv6ch2"
http.Open "POST", url, False
http.Send
MsgBox http.responsetext
End Sub
有一种更简单的方法。值得添加的标头是User-Agent,它可以减轻提供给缓存结果的负担。下面显示了如何在指定的时间段内从服务器获取json响应并写入Excel。注意:您需要将代码连接到URL中。您可能还应该测试服务器的响应代码以确保成功。
我使用jsonconverter.bas作为json解析器来处理响应。从here下载原始代码,并将其添加到名为JsonConverter的标准模块中。然后,您需要转到VBE>工具>引用>添加对Microsoft脚本运行时的引用。从复制的代码中删除最上面的属性行。
startDate
和endDate
的值需要作为unix时间戳传递。 @TimWilliams编写了一个很好的函数toUnix
,用于将Date转换为我使用的Unix here。我添加了自己的功能来管理相反的转化。
此方法避免使用任何基于会话的标识符,因此避免了无效的曲奇面包屑的问题。
VBA:
Option Explicit
Public Sub GetYahooHistoricData()
Dim ticker As String, ws As Worksheet, url As String, s As String
Dim startDate As Long, endDate As Long
Set ws = ThisWorkbook.Worksheets("Sheet1")
ticker = ws.Range("ticker") 'Range A1. Above write out range
endDate = toUnix("2019-10-27")
startDate = toUnix("2018-10-25")
url = "https://query1.finance.yahoo.com/v8/finance/chart/" & ticker & "?region=US&lang=en-US&includePrePost=false&interval=1d&period1=" & startDate & "&period2=" & endDate & "&corsDomain=finance.yahoo.com&.tsrc=finance"
With CreateObject("MSXML2.XMLHTTP")
.Open "GET", url, False
.setRequestHeader "User-Agent", "Mozilla/5.0"
.setRequestHeader "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"
.send
s = .responseText
End With
Dim json As Object
Set json = JsonConverter.ParseJson(s)("chart")("result")
Dim dates As Object, results(), rows As Object, adjClose As Object, r As Long, headers()
headers = Array("date", "close", "volume", "open", "high", "low", "adjclose")
Set dates = json(1)("timestamp")
ReDim results(1 To dates.Count, 1 To UBound(headers) + 1)
Set rows = json(1)("indicators")("quote")(1)
Set adjClose = json(1)("indicators")("adjclose")(1)("adjclose")
For r = 1 To dates.Count
results(r, 1) = GetDate(dates(r))
results(r, 2) = rows("close")(r)
results(r, 3) = rows("volume")(r)
results(r, 4) = rows("open")(r)
results(r, 5) = rows("high")(r)
results(r, 6) = rows("low")(r)
results(r, 7) = adjClose(r)
Next
With ws
.Cells(3, 1).Resize(1, UBound(headers) + 1) = headers
.Cells(4, 1).Resize(UBound(results, 1), UBound(results, 2)) = results
End With
End Sub
Public Function GetDate(ByVal t As Variant) As String
GetDate = Format$(t / 86400 + DateValue("1970-01-01"), "yyyy-mm-dd")
End Function
Public Function toUnix(ByVal dt As Variant) As Long
toUnix = DateDiff("s", "1/1/1970", dt)
