带有哈希字符的XMLHTTP

Question

我正在尝试用xmlhttp和VBA抓取一个网站。 Url有一个哈希（＃）符号，被VBA误解了...... 这与此处解释的问题相同：Error in XMLHTTP Get request with Special character in URL 代码如下：

Sub webscraping()
Dim x               As String
Dim req             As MSXML2.XMLHTTP60
Dim doc             As HTMLDocument

x = "https://search.gleif.org/#/search/"

Set req = New MSXML2.XMLHTTP60
    With req
        .Open "GET", x, False
        .send
        If .Status <> 200 Then
            MsgBox "Http Request Error"
            Exit Sub
        End If
        Set doc = New MSHTML.HTMLDocument
        doc.body.innerHTML = .responseText
    End With
End Sub

先感谢您

您可以通过直接使用搜索字词调用API来执行此操作，如下所示。我正在使用json parser来处理json响应。在项目链接中添加.bas之后，还可以去VBE>工具>参考>添加对Microsoft Scripting Runtime的引用。

请注意，您可以在此处更改queryString参数："&page%5Bnumber%5D=1&page%5Bsize%5D=15"。目前这是页面= 1和每页15的记录。

VBA：

Option Explicit
Public Sub webscraping()
    Dim url As String
    Dim req As MSXML2.XMLHTTP60
    Dim doc As HTMLDocument
    Dim json As Object
    Const TERM = "banana corp."

    url = "https://api.gleif.org/api/v1/lei-records?filter%5Bfulltext%5D=" & Application.EncodeURL(TERM) & "&page%5Bnumber%5D=1&page%5Bsize%5D=15"

    Set req = New MSXML2.XMLHTTP60
    With req
        .Open "GET", url, False
        .send
        If .Status <> 200 Then
            MsgBox "Http Request Error"
            Exit Sub
        End If
        Set json = JsonConverter.ParseJson(.responseText)
    End With
    Stop
    'Do something with json
End Sub

返回了很多信息，所以这里只是它的摘录：

在这里研究API：
