Question

到目前为止我已经尝试过了：

Dim wreq As HttpWebRequest = WebRequest.Create("http://www.nasdaq.com/symbol/goog/financials?query=income-statement&data=quarterly")
    wreq.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5"
    wreq.Method = "get"
    Dim prox As IWebProxy = wreq.Proxy
    prox.Credentials = CredentialCache.DefaultCredentials
    Dim document As New HtmlAgilityPack.HtmlDocument
    Dim web As New HtmlAgilityPack.HtmlWeb
    web.UseCookies = True
    web.PreRequest = New HtmlAgilityPack.HtmlWeb.PreRequestHandler(AddressOf onPreReq)
    wreq.CookieContainer = cookies
    Dim res As HttpWebResponse = wreq.GetResponse()
    document.Load(res.GetResponseStream, True)
    Debug.WriteLine(document.DocumentNode.OuterHtml)

但它会返回此网址的HTML：http://www.nasdaq.com/symbol/goog/financials?query=income-statement

而不是这一个：http://www.nasdaq.com/symbol/goog/financials?query=income-statement&data=quarterly

我做错了什么？

其他信息

以下是onPreReq

Private Function onPreReq(req As HttpWebRequest)

    req.CookieContainer = cookies
    Return True

End Function

问题在于我的变量Ticker。它包含我用来创建Web地址的股票代码。到目前为止，我一直在使用所有上限（例如GOOG）。我把所有的代码改为小写（例如goog），这似乎已经成功了。
