示例

下面的代码示例显示 HTTP 请求中所有标头的名称和值。The following code example displays the names and values of all headers in the HTTP request.

int loop1, loop2;
NameValueCollection coll;
 
// Load Header collection into NameValueCollection object.
coll=Request.Headers;

// Put the names of all keys into a string array.
String[] arr1 = coll.AllKeys; 
for (loop1 = 0; loop1<arr1.Length; loop1++) 
{
   Response.Write("Key: " + arr1[loop1] + "<br>");
   // Get all values under this key.
   String[] arr2=coll.GetValues(arr1[loop1]);
   for (loop2 = 0; loop2<arr2.Length; loop2++) 
   {
      Response.Write("Value " + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>");
   }
}
   

Dim loop1, loop2 As Integer
 Dim arr1(), arr2() As String
 Dim coll As NameValueCollection
 

' Load Header collection into NameValueCollection object.
coll=Request.Headers

' Put the names of all keys into a string array.
arr1 = coll.AllKeys 
For loop1 = 0 To arr1.GetUpperBound(0)
   Response.Write("Key: " & arr1(loop1) & "<br>")
   arr2 = coll.GetValues(loop1) 
   ' Get all values under this key.
   For loop2 = 0 To arr2.GetUpperBound(0)
      Response.Write("Value " & CStr(loop2) & ": " & Server.HtmlEncode(arr2(loop2)) & "<br>")
    Next loop2
 Next loop1
