我将如何使用 aspjson 和经典 asp 遍历 json 数组？

Question

的帮助下走到了这一步

<!--#include file="aspjson.asp" -->

jsonstring = "{""events"":""[{
""email"":""john@test.com"",
""timestamp"":1461015166,
""smtp-id"":""\u003c14c5d75ce93.dfd.64b469@ismtpd-555\u003e"",
""event"":""processed"",
""category"":""cat facts"",
""sg_event_id"":""Y4SkYnMgWCH-j0Ap2HUBlg=="",
""sg_message_id"":""14c5d75ce93.dfd.64b469.filter0001.16648.5515E0B88.0""
},
{
"email"":""example@test.com"",
""timestamp"":1461015166,
""smtp-id"":""\u003c14c5d75ce93.dfd.64b469@ismtpd-555\u003e"",
""event"":""deferred"",
""category"":""cat facts"",
""sg_event_id"":""QVvoFUd9LS5083KTavaqAw=="",
""sg_message_id"":""14c5d75ce93.dfd.64b469.filter0001.16648.5515E0B88.0"",
""response"":""400 try again later"",""attempt"":""5""
},
{
""email"":""john@test.com"",
""timestamp"":1461015166,
""smtp-id"":""\u003c14c5d75ce93.dfd.64b469@ismtpd-555\u003e"",
""event"":""processed"",
""category"":[""Cat Facts"",""Fish Facts""],
""sg_event_id"":""Y4SkYnMgWCH-j0Ap2HUBlg=="",
""sg_message_id"":""14c5d75ce93.dfd.64b469.filter0001.16648.5515E0B88.0""
}]""}"


Set jJSON = New aspJSON
jJSON.loadJSON(jsonstring)

For Each son In jJSON.data("events")
For Each grandson In jJSON.data("events").item(son)
    response.write "<b>" & grandson & ": </b>" & jJSON.data("events").item(son).item(grandson) & "<br>"
Next
response.write "<br>"
Next

我找到的大多数示例都有键的名称，但我并不总是知道它们是什么。

当我的循环到达类别包含两个元素的最后一组时，我的问题就来了。 "Cat Facts" 和 "Fish Facts"。

错误信息是： Microsoft VBScript 运行时错误“800a01c2” 参数数量错误或无效属性赋值

如果我能让它工作，那将是朝着正确方向迈出的一步，但是 "Categories" 可以是另一条记录中的任何名称，它可以有一个或多个值。

我想我需要添加一个 if/then 但我被困在这里了。我想我想做这样的伪代码

if isarray(grandson) then
for each greatgrandson in grandson
    response.write greatgrandson
else
    response.write "<b>" & grandson & ": </b>" & jJSON.data("events").item(son).item(grandson) & "<br>"
end if

我敢肯定，很明显，我仍在为如何将所有这些组合在一起而苦苦挣扎，因此，如果有人有任何可能有用的指示或指向描述的链接，我们将不胜感激。

您可以检查孙子是否是一个对象，如果它循环显示：

For Each son In jJSON.data("events")
For Each grandson In jJSON.data("events").item(son)
    response.write "<b>" & grandson & ": </b>"
    if NOT isObject(jJSON.data("events").item(son).item(grandson)) then
        response.write jJSON.data("events").item(son).item(grandson) 
    else
        for each category in jJSON.data("events").item(son).item(grandson)
            Response.write jJSON.data("events").item(son).item(grandson)(category) & ","
        next
    end if
    Response.write "<br>"
Next
response.write "<br>"
Next

How would I iterate through json array using aspjson with classic asp?
