A potentially dangerous Request. Path value was detected from the client exception solution, potentially

Scenario:

When the URL contains A special character "<,>, *, %, &,:,/", the page throws A potentially dangerous Request. Path value was detected from the client exception.

 

Cause:

It is the default Interception Mechanism of ASP. NET to ensure the security of page URL transmission.

 

There are two solutions:

First, remove dangerous character verification for page requests directly:

Add the following code to the <system. web> node of the web. config configuration file:

1 <system.web>2    
 
Second, set which dangerous characters need to be verified:
1 <system.web>2     
Note that the requestPathInvalidCharacters is a list of invalid characters separated by commas. If this key-Value Pair does not exist by default, it means that the restricted invalid character set (separated by commas) is the seven: <,>, *, % ,&,:,/
If you want these characters to be unrestricted, set requestPathInvalidCharacters = "";
If you want to restrict some characters, you need to set the characters to be restricted in requestPathInvalidCharacters. For example, requestPathInvalidCharacters = "<,> ".
