简而言之，我有一个Web应用程序，以前能够设置好的cookie，但它不再有效。真正奇怪的是我已经使用了Chrome的调试器来跟踪正在发生的事情，它使得“document.cookie =”声明一直很好。
此外，我没有更改任何内容，除了cookie的内容（添加更多信息）。我根本没有修改cookie设置逻辑，甚至没有修改参数。
以下是我的应用程序的最新版本：http://asmor.com/scripts/tsrand/alpha/
相关位是第147-149行，http://asmor.com/scripts/tsrand/alpha/init.js
cookie=JSON.stringify(opt)
log("Cookie: "+cookie);
$.cookie(cookieName, cookie, { expires: 365 });
opt是我用来存储表单元素值的对象。我将对象转换为JSON字符串，然后存储它。以下是此版本程序中包含cookie的示例：
{"diseaseSelect":".5","soloGame":"checkbox:false","showLog":"checkbox:true","min_Setting":"0","max_Setting":"1","cardBarrowsdale":"Maybe","cardDoomgate":"Maybe","cardDragonspire":"Maybe","cardDreadwatch":"Maybe","cardFeaynSwamp":"Maybe","cardGrimhold":"Maybe","cardRegianCove":"Maybe","min_Thunderstone":"1","max_Thunderstone":"1","cardStoneofAgony":"Maybe","cardStoneofAvarice":"Maybe","cardStoneofMystery":"Maybe","cardStoneofScorn":"Maybe","cardStoneofTerror":"Maybe","min_Monster":"3","max_Monster":"3","cardAbyssal":"Maybe","cardAbyssalThunderspawn":"Maybe","cardBanditHumanoid":"Maybe","cardCultistHumanoid":"Maybe","cardDarkEnchanted":"Maybe","cardDoomknightHumanoid":"Maybe","cardDragon":"Maybe","cardElementalFire":"Maybe","cardElementalNature":"Maybe","cardElementalPain":"Maybe","cardEnchanted":"Maybe","cardEvilDruidHumanoid":"Maybe","cardGiant":"Maybe","cardGolem":"Maybe","cardHorde":"Maybe","cardHumanoid":"Maybe","cardHydraDragon":"Maybe","cardOoze":"Maybe","cardOrcHumanoid":"Maybe","cardTheSwarm":"Maybe","cardUndeadDoom":"Maybe","cardUndeadLich":"Maybe","cardUndeadPlague":"Maybe","cardUndeadSpirit":"Maybe","cardUndeadStormwraith":"Maybe","min_Guardian":"0","max_Guardian":"1","cardDarkChampion":"Maybe","cardDeathSentinel":"Maybe","cardGuardianofNight":"Maybe","cardGuardianofTorment":"Maybe","cardUnholyGuardian":"Maybe","min_Trap":"0","max_Trap":"1","cardTrapDeath":"Maybe","cardTrapDire":"Maybe","cardTrapDraconic":"Maybe","min_Treasure":"0","max_Treasure":"1","cardAmuletTreasure":"Maybe","cardFigurineTreasure":"Maybe","cardUlbricksTreasure":"Maybe","min_Hero":"4","max_Hero":"4","cardAmazon":"Maybe","cardBelzur":"Maybe","cardBlind":"Maybe","cardCabal":"Maybe","cardChalice":"Maybe","cardChulian":"Maybe","cardClan":"Maybe","cardDeep":"Maybe","cardDiin":"Maybe","cardDrunari":"Maybe","cardDivine":"Maybe","cardDwarf":"Maybe","cardElf":"Maybe","cardEvoker":"Maybe","cardFeayn":"Maybe","cardFlame":"Maybe","cardGangland":"Maybe","cardGohlen":"Maybe","cardGorinth":"Maybe","cardHalf-Orc":"Maybe","cardLorigg":"Maybe","cardOutlands":"Maybe","cardPhalanx":"Maybe","cardRedblade":"Maybe","cardRegian":"Maybe","cardRunespawn":"Maybe","cardSelurin":"Maybe","cardSidhe":"Maybe","cardSlynn":"Maybe","cardStoneguard":"Maybe","cardTempest":"Maybe","cardTerakian":"Maybe","cardTholis":"Maybe","cardThyrian":"Maybe","cardToryn":"Maybe","cardVerdan":"Maybe","cardVeteran":"Maybe","min_Village":"8","max_Village":"8","cardAmbrosia":"Maybe","cardAmuletofPower":"Maybe","cardArcaneEnergies":"Maybe","cardBanish":"Maybe","cardBarkeep":"Maybe","cardBattleFury":"Maybe","cardBlacksmith":"Maybe","cardBlessedHammer":"Maybe","cardBluefireStaff":"Maybe","cardBorderGuard":"Maybe","cardBurntOffering":"Maybe","cardChieftansDrum":"Maybe","cardClaymore":"Maybe","cardCreepingDeath":"Maybe","cardCursedMace":"Maybe","cardCyclone":"Maybe","cardDivineStaff":"Maybe","cardDoomgateSquire":"Maybe","cardFeast":"Maybe","cardFireball":"Maybe","cardFlamingSword":"Maybe","cardFlaskofOil":"Maybe","cardForesightElixir":"Maybe","cardFortuneTeller":"Maybe","cardFrostBolt":"Maybe","cardFrostGiantAxe":"Maybe","cardGlowberries":"Maybe","cardGoodberries":"Maybe","cardGreedBlade":"Maybe","cardGuardianBlade":"Maybe","cardGuide":"Maybe","cardHatchet":"Maybe","cardIllusoryBlade":"Maybe","cardLantern":"Maybe","cardLightstoneGem":"Maybe","cardMagiStaff":"Maybe","cardMagicMissile":"Maybe","cardMagicalAura":"Maybe","cardPawnbroker":"Maybe","cardPiousChampion":"Maybe","cardPolearm":"Maybe","cardPolymorph":"Maybe","cardQuartermaster":"Maybe","cardRecurveBow":"Maybe","cardSage":"Maybe","cardScout":"Maybe","cardShortBow":"Maybe","cardShortSword":"Maybe","cardSilverstorm":"Maybe","cardSkullbreaker":"Maybe","cardSoulGem":"Maybe","cardSoulJar":"Maybe","cardSpear":"Maybe","cardSpiritBlast":"Maybe","cardSpiritHunter":"Maybe","cardSpoiledFood":"Maybe","cardTavernBrawl":"Maybe","cardTaxCollector":"Maybe","cardThunderRing":"Maybe","cardTorynGauntlet":"Maybe","cardTownGuard":"Maybe","cardTrader":"Maybe","cardTrainer":"Maybe","cardWarhammer":"Maybe"}
现在，这是我拥有的最早的备份副本：http://asmor.com/scripts/tsrand/backup/2010-09-13/dev/
此副本仍然有效。
以下是该副本中的cookie设置逻辑，第130-132行http://asmor.com/scripts/tsrand/backup/2010-09-13/dev/scripts/init.js
cookie=JSON.stringify(opt)
log("Cookie: "+cookie);
$.cookie(cookieName, cookie, { expires: 365 });
该示例的cookie包含的示例：
{"guardianSelect":".5","trapSelect":"1","monstersSelect":"3","heroesSelect":"4","villageSelect":"8","soloGame":"checkbox:false","useConditions":"checkbox:true","showLog":"checkbox:true","setBase":"checkbox:false","setPromo":"checkbox:true","setWrathOfTheElements":"checkbox:false","cardAbyssal":"Maybe","cardDoomknightHumanoid":"Maybe","cardDragon":"Maybe","cardElementalNature":"Maybe","cardElementalPain":"Maybe","cardEnchanted":"Maybe","cardGolem":"Maybe","cardHorde":"Maybe","cardHumanoid":"Maybe","cardOoze":"Maybe","cardUndeadDoom":"Maybe","cardUndeadSpirit":"Maybe","cardDarkChampion":"Maybe","cardDeathSentinel":"Maybe","cardTrapDeath":"Maybe","cardTrapDire":"Maybe","cardAmazon":"Maybe","cardBlind":"Maybe","cardChalice":"Maybe","cardClan":"Maybe","cardDiin":"Maybe","cardDivine":"Maybe","cardDwarf":"Maybe","cardElf":"Maybe","cardFeayn":"Maybe","cardGangland":"Maybe","cardGohlen":"Maybe","cardLorigg":"Maybe","cardOutlands":"Maybe","cardRedblade":"Maybe","cardRegian":"Maybe","cardRunespawn":"Maybe","cardSelurin":"Maybe","cardThyrian":"Maybe","cardToryn":"Maybe","cardAmbrosia":"Maybe","cardAmuletofPower":"Maybe","cardArcaneEnergies":"Maybe","cardBanish":"Maybe","cardBarkeep":"Maybe","cardBattleFury":"Maybe","cardBlacksmith":"Maybe","cardClaymore":"Maybe","cardCreepingDeath":"Maybe","cardCursedMace":"Maybe","cardFeast":"Maybe","cardFireball":"Maybe","cardFlamingSword":"Maybe","cardForesightElixir":"Maybe","cardGoodberries":"Maybe","cardHatchet":"Maybe","cardIllusoryBlade":"Maybe","cardLantern":"Maybe","cardLightstoneGem":"Maybe","cardMagiStaff":"Maybe","cardMagicMissile":"Maybe","cardMagicalAura":"Maybe","cardPawnbroker":"Maybe","cardPolearm":"Maybe","cardSage":"Maybe","cardShortBow":"Maybe","cardShortSword":"Maybe","cardSpear":"Maybe","cardTavernBrawl":"Maybe","cardTaxCollector":"Maybe","cardTownGuard":"Maybe","cardTrainer":"Maybe","cardWarhammer":"Maybe"}
我正在使用JSON库和设置/获取cookie。早期版本和最新版本都使用完全相同的库完全相同的版本。
我唯一能想到的是，cookie已经变得多了两倍多。在URI编码之前，我们说的是4000个字符而不是1800个字符。此外，我URI编码了更新的cookie并自己手动设置它，浏览器接受它就好了，我的程序装得很好。
我完全没有想法。救命啊！

4096字节限制;否则整个cookie都会被IE丢弃。

如果可能，您应该将所有这些数据存储在服务器上的会话中，而不是拥有大量的cookie。然后，您可以通过AJAX简单地请求数据或将其嵌入到每个页面请求中。
浏览器只需要为每个cookie提供4KB的空间，所以如果你已经结束，那么它可能无法存储。
