由於對RESTful Web服務的調用實際上只是一種特定類型的HTTP請求,您至少可以使用Microsoft XML庫向Web服務發送HTTP請求並解析返回的任何內容。例如,當我運行下面的VBA代碼
' VBA project Reference required:
' Microsoft XML, v3.0
Dim httpReq As New MSXML2.ServerXMLHTTP
httpReq.Open "GET", "http://whois.arin.net/rest/poc/KOSTE-ARIN", False
httpReq.send
Dim response As String
response = httpReq.responseText
Debug.Print response
字符串變量response
包含了我的請求,XML響應。它看起來像這樣(爲重新格式化後的可讀性):
<?xml version='1.0'?>
<?xml-stylesheet type='text/xsl' href='http://whois.arin.net/xsl/website.xsl' ?>
<poc xmlns="http://www.arin.net/whoisrws/core/v1" xmlns:ns2="http://www.arin.net/whoisrws/rdns/v1"

什麼得到由Web服務返回的可能看起來有些不同。或者,正如上述ARIN whois RWS的情況一樣,您可能有幾種數據格式供您選擇; XML只是默認值。我可以要求使用
httpReq.Open "GET", "http://whois.arin.net/rest/poc/KOSTE-ARIN.txt", False
一個純文本的反應在這種情況下response
將包含
