Question

我在ASP中创建了一个名为language的cookie，它被设置为字符串"VBScript"。我已将Expires属性附加到#May 1,2016#的值<% response.write("Cookie: " & Request.Cookies("language")) ' outputs 'VBScript' response.write("Expiration Date: " & Request.Cookies("language").Expires) ' possible line of error %>。我能够检索cookie的值，但是我在检索到期日期时遇到了问题。这是ASP代码：

#include <stdio.h>

#define STRSIZE 20

/* Structure definitions   */
typedef struct {
        int     month,
                day,
                year;
} date_t;

typedef struct {
        double  capacity,
                current;
} tank_t;

typedef struct {
        char    make[STRSIZE],
                model[STRSIZE];
        int     odometer;
        date_t  manuf,
                purch;
        tank_t  tank;
} auto_t;

/*

void print_auto(auto_t vehicle); 

int main()
{
    auto_t      vehicle;
    int         number=0,
                i=0,
                status=1;

    FILE *inp = fopen("autos.txt","r");                /* defining file input    */

    /* Check to make sure input file is found and readable.  */
    if(inp==NULL){
        printf("Error: Input file - autos.txt - not found!\n");

        getch();
        return 0;
    }

    printf("Vehicle   Vehicle  Odometer  Date        Date          Tank       Current\n");
    printf("Make      Model    Reading   Purchased   Manufactured  Capacity   Fuel Level\n");
    printf("\n----------------------------------------------------------------------------\n\n");

当我运行此代码时，在cookie的值旁边，它显示“处理URL时出错”。请联系系统管理员。如果您是系统管理员，请单击此处以了解有关此错误的更多信息。＆＃39;这里＆＃39; part是微软网站的链接。我可以考虑删除可能的错误行，但有没有办法在这种情况下检索cookie的过期日期？

更新

删除可能的错误行＆＃39;刚刚删除了错误消息，只显示了cookie的值。

Answer 1

来自：Response.Cookies Collection

过期
只写。 Cookie过期的日期。这个日期必须设置，以便将Cookie存储在客户端的磁盘上会议结束后。如果此属性未设置为超出日期当前日期，Cookie会话结束时到期。

这是一个只写值，无法从中读取。

Request.Cookies集合没有名为Expires的密钥。

如何检索＆＃39; Expires＆＃39; ASP cookie的属性？
