推荐答案

更新：解决方案



我找到了一个对我有用的解决方案，当我进一步研究时就此而言。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，它是在注册表中定义的。



所以，你必须更新注册表以增加IIS服务器/ IIS Express运行时的大小限制。



以下是注册表的位置：



HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet \services \HTTP \Parameters



值名称为UrlSegmentMaxLength。如果不存在，请使用类型REG_DWORD创建一个。并为值数据指定更高的值，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



确保重启服务器/机器以应用注册表更改。就是这样。

UPDATE: SOLUTION

I Found a solution which worked for me, when I research further on this. I'm updating here since it might be useful for others who come across this question.

This is an IIS Setting

The problem is because, the default character limit of each parameter in REST url is 260 which is defined in the registry.

So, you have to update the registry to increase this size limit where the IIS Server / IIS Express is running.

Following is the location of Registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters

And the value name is UrlSegmentMaxLength. If it is not there, create one with Type of REG_DWORD. And specify a higher value for value data such as 1000 in hexadecimal or 4096 in decimal.

This is a http.sys setting. More about http.sys settings : http://support.microsoft.com/kb/820129

Make sure, you restart the server/machine to apply the registry changes. And that's it.
