Question

我有一个长值的cookie，我在下面粘贴了一个例子。我需要拆分名称值对并返回，在这种情况下＆＃34; id＆＃34;从下面对应167814329。

我无法阅读开发人员在这里使用的语法（我是分析师而非开发工程师）。在过去，我见过与=或＆＃39; |＆＃39;一起使用的名称值对。语法作为分隔符。

看起来名称值对就是这样：

%22id%22%3A167814329%2C

var usd = document.cookie.match(/(^| )user_session_data\=([^;]*)(;|$)/)[0]
var arr = usd.split('%22')
var ind = arr.indexOf('id');
var pair = arr[ind];

但是对等于＆＃34; id＆＃34;只是，我希望得到这个数组值%22id%22%3A167814329%2C然后我可以拆分。

获得167814329会是一个干净的正则表达式吗？

以下是要搜索的示例Cookie值：

Answer 1

似乎如果你删除了开头的user_session_data和最后的;，你就得到了一个转义字符串。你可以unescape它，并获得你的id（它实际上是一个JSON对象）：

var obj = "%7B%22lastUpdated%22%3A1476155189.373%2C%22active%22%3Afalse%2C%22uType%22%3A%22none%22%2C%22entitled%22%3Afalse%2C%22gift%22%3Afalse%2C%22stacked%22%3A%22none%22%2C%22usedsomestringFreeTrial%22%3A%22none%22%2C%22cancelled%22%3A%22none%22%2C%22displayName%22%3A%2220161010_gpc%40example.com%22%2C%22email%22%3A%2220161010_gpc%40example.com%22%2C%22userName%22%3A%2220161010_gpc%40example.com%22%2C%22firstName%22%3Anull%2C%22salesChannel%22%3A%22cat%22%2C%22marketingOptIn%22%3Atrue%2C%22newIssueEmailNotifyEnabled%22%3Afalse%2C%22restartSubscriptions%22%3A%5B%5D%2C%22id%22%3A167814329%2C%22purchaseType%22%3A%22NONE%22%2C%22futurePurchaseType%22%3A%22NONE%22%2C%22somestringStatus%22%3Anull%2C%22hasFuturePrivilege%22%3Afalse%2C%22rogersUser%22%3Afalse%2C%22suspendedStatus%22%3Anull%2C%22socialEmail%22%3A%22%22%2C%22somestringOffersStale%22%3Anull%2C%22somestringcabbagesPrice%22%3Anull%2C%22somestringcabbagesId%22%3Anull%2C%22somestringcabbagesFreeTrial%22%3Anull%2C%22somestringcabbagesOfferPackageId%22%3Anull%2C%22somestringcarrotsPrice%22%3Anull%2C%22somestringcarrotsId%22%3Anull%2C%22somestringcarrotsFreeTrial%22%3Anull%2C%22somestringcarrotsOfferPackageId%22%3Anull%2C%22launchedFromReader%22%3Anull%2C%22userPaymentMethod%22%3Anull%2C%22iseligibleforfreetrial%22%3Atrue%2C%22loginTimeStamp%22%3A%22Tue%20Oct%2011%202016%2011%3A06%3A29%20GMT%2B0800%20(PHT)%22%2C%22latestSubscriptionSource%22%3Anull%7D"

var myObject = JSON.parse(unescape(obj));
console.log(myObject.id); //167814329

HanletEscaño肯定有最准确的答案，但是如果你真的想要使用正则表达式，你可以。目前还不清楚你是想要id%22%3a[ID]%2C还是仅仅是ID，所以这里有两个：

完整字符串：(?:^| )user_session_data\=[^;]*(id%22%3A\d+%2C)[^;]*(?:;|$)

只是ID：(?:^| )user_session_data\=[^;]*id%22%3A(\d+)%2C[^;]*(?:;|$)

将来，如果您在使用正则表达式时遇到问题，this site可能非常有用。

这个cookie值的正则表达式？
