我收到此错误:

此请求的URL长度超过配置的maxUrlLength值.

环顾我能找到的最接近的东西是在web.config中,

<requestFiltering>
   <requestLimits maxUrl="xxx">
</requestFiltering>

然而,这不是MaxUrlLength,也不解决问题.任何想法如何解决？

我试图通过使用GET方法的jQuery AJAX调用来访问WCF服务.因此,有时URL的参数很长.

当参数变得如此冗长时,jQuery AJAX调用失败,并且什么都不返回.所以我提出了一个断点并把URL拿出去测试.当我在浏览器中尝试使用相同的URL时(我尝试过FireFox和Chrome),当URL长度过长时会返回以下内容.

错误请求 - 无效的网址

HTTP错误400.请求URL无效.

我也检查了长度限制.当URL中的字符数(编码格式)超过1011个字符(包括http://)时,我才会收到错误.

任何人都有相同的情况,并找到任何解决方案吗？是Windows限制还是可以通过编程方式通过任何设置进行管理？

我试过POST方法,但我不知道我无法使它工作.因为它需要一些web.config更改.

未编码的URL版本:

http://localhost:64973/Member.svc/SaveMemberWithDetail/{"ID"|"2","TypeID"|"2","Title"|"Mr.","FirstName"|"Firnas","MiddleName"|"","LastName"|"Aliyar","Gender"|"1","DateOfBirth"|"2000-01-01","Nationality"|"Sri Lankan"}/[{"AddressLine1"|"Changed Address Line1","AddressLine2"|"Colombo","City"|"Colombo 10","State"|"WP","PostCode"|"01000","CountryID"|"1","ID"|"7","TypeID"|"1"}]/[{"Telephone"|"015154645","TypeID"|"1"}]/[{"EmailAddress"|"gen1@dfs","ID"|"26","TypeID"|"1"},{"EmailAddress"|"gen2@jfasd","ID"|"27","TypeID"|"1"},{"EmailAddress"|"g1@e.cm","ID"|"28","TypeID"|"1"},{"EmailAddress"|"g2@gogle.com","ID"|"29","TypeID"|"1"},{"EmailAddress"|"g@go.com","ID"|"29","TypeID"|"1"}]/{}/481

我的参数是Json对象的集合.我不认为任何字符会导致问题,因为,如果我只是将少数字母数字字符减少到小于限制,它就可以工作.

我正在使用Windows 8 Professional中的Visual Studio 2012 Premium运行我的应用程序,所以它是.NET 4.5和IIS Express随之而来.

进一步的研究

当我试图进一步调查时,这不是我已经提到的限制,即完整网址的长度.但是,每个参数的长度限制为260个字符.

所以,我不确定URL的总长度,但是每个参数(用"/"分隔)都有限制.我发布的上述URL的问题是电子邮件地址JSON参数长度为261个字符,如下所示.

[{"EmailAddress"|"gen1@dfs","ID"|"26","TypeID"|"1"},{"EmailAddress"|"gen2@jfasd","ID"|"27","TypeID"|"1"},{"EmailAddress"|"g1@e.cm","ID"|"28","TypeID"|"1"},{"EmailAddress"|"g2@gogle.com","ID"|"29","TypeID"|"1"},{"EmailAddress"|"g@go.com","ID"|"29","TypeID"|"1"}]

如果我从中删除1个字符,它就可以了.

是浏览器限制吗？操作系统限制？

更新:解决方案

当我进一步研究这个问题时,我找到了一个对我有用的解决方案.我在这里更新,因为它可能对遇到这个问题的其他人有用.

这是一个IIS设置

问题是因为,REST url中每个参数的默认字符限制是260,它在注册表中定义.

因此,您必须更新注册表以增加运行IIS Server/IIS Express的此大小限制.

以下是注册表的位置:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters

值名称是UrlSegmentMaxLength.如果不存在,请使用Type of创建一个REG_DWORD.并指定一个更高的值,value data例如十六进制的1000或十进制的4096.

这是一个http.sys设置.有关http.sys设置的更多信息:http://support.microsoft.com/kb/820129

确保重新启动服务器/计算机以应用注册表更改.就是这样.

我正在开发一个 Asp.Net Core 应用程序。我使用内置身份进行登录、角色、授权和身份验证。我正在 Windows 机器上使用 IIS Express 进行开发/测试/调试。当我以非管理员用户身份登录并尝试导航到只有管理员有权访问的 url（整个控制器上的授权属性）时，应用程序重定向到访问被拒绝的 URL，但随后我收到一条错误消息说url查询字符串太长。检查 url 后，它似乎有重复的部分。我会试着把它贴在下面。我应该将此报告为错误，还是可以更改设置以防止它？

我正在 MVC 平台上工作，并且使用 JSON GET 调用 jqGrid。

我已阅读Request Limits、maxQueryStringLength、maxAllowedContentLength、URL 最大长度并配置web.config如下

<httpRuntime maxRequestLength="2147483647" executionTimeout="1200" requestValidationMode="2.0" maxQueryStringLength="2097151" maxUrlLength ="65536"/>

&

<requestLimits maxUrl ="65536" maxAllowedContentLength="4294967295" maxQueryString ="2097151" />

但它仍然给我错误414 (Request-URI Too Long)。

知道有什么办法可以解决这个问题吗？

编辑：

根据 Rory 的评论，我将 GET 请求更改为 POST。通过更改它应该可以解决问题。可以在这里找到讨论。但是，在更改它并通过ASP.Net Core maxUrlLength后我仍然面临同样的问题

我有一个asp.net核心网络API，可启用tts请求。您基本上要求http://server.url/Whatever you want it to say.mp3获得带有tts语音文本的mp3。

但是问题是，400 - The request URL is invalid如果我传递一个长字符串，它将返回a 。好像服务器正在达到某种最大URL长度限制。我可以找到有关如何解决此问题的信息，这是“经典” asp.net web.config，而在asp.net核心中却找不到如何解决此问题。

在asp.net核心中增加最大URL长度的正确方法是什么？

更新：

确切的网址例如是：

http：// localhost：5000 / api / mp3 / nl-NL / male / 1 / Wikipedia％20is％20een％20online％20encyclopedie％20die％20tracht％20inhoud％20te％20bieden％20die％20vrij％20herbruikbaar，％20objectief％20en ％20verifieerbaar％20is。％20Het％20project％20is％20gebouwd％20op％20vijf％20zuilen。％20De％20Nederlandstalige％20versie％20startte％20op％2019％20juni％202001％20en％20is，％20gemeten％20naar％20het％20aant 20artikelen，％20met％20bijna％201,9％20miljoen％20artikelen％20de％20op％20vier％20na％20grootste％20taalversie.mp3

它是URL编码的。我将尝试找出确切的最大值。

我无法使用POST，因为要利用它的工具仅支持mp3文件的网址（因此，在控制器中使用了.mp3扩展名）。

更新2

它接受的最长请求包含397个字符，这似乎不太合逻辑。如果再添加一个，它将返回代码400。

更新3

事实证明，仅当将其部署在服务器上（使用IIS），在本地运行时，它才支持更长的字符串（我还没有看到它返回代码400）。我将不得不调查IIS，看看它出了什么问题。
