错误的请求 - 无效的URL网页API [英] Bad Request - Invalid URL web api

问题描述

我工作的一个Web API和我已经设置了网络配置文件，接受6144作为URL的最大长度如下

I am working on a web-api and I have set the web config file to accept 6144 as the max length of the url as below

<system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime maxUrlLength="6144" 
                 relaxedUrlToFileSystemMapping="true"
                 targetFramework="4.5"/>

当我把299个字符一切工作正常，但有超过299个字符它提供了一个错误的请求的API - 无效的网址

When I call the api with 299 characters everything works fine, but with more than 299 characters it serves up a Bad Request - Invalid URL

推荐答案

我在自我托管Web的API有同样的问题。我猜你打的限制是 UrlSegmentMaxLength 默认从Http.sys的。

I've had the same issue when self hosting web-api. I would guess the limit you are hitting is the UrlSegmentMaxLength default from Http.sys.

要解决这个问题，你需要添加的新的的下

To fix this you need to add a new registry DWORD under

HKEY_LOCAL_MACHINE \\系统\\ CurrentControlSet \\服务\\ HTTP \\参数

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters

名为 UrlSegmentMaxLength ，并给这个你想要的值：

called UrlSegmentMaxLength and give this the value you desire:

UrlSegmentMaxLength 260 0 - 32,766字符URL路径段的最大字符数（在URL中斜杠之间的部分）。如果为零，它是受ULONG最大值的限制长度。

UrlSegmentMaxLength 260 0 - 32,766 chars Maximum number of characters in a URL path segment (the area between the slashes in the URL). If zero, it is the length that is bounded by the maximum value of a ULONG.
