Re: [Cppcms-users] question about mapper

[4. <440...@qq...>]

I see your email say that
 if regular expression is "^/page/(\\d+)/(\\w+)$" , exp1=2,
 why exp1 = 2 ？ use your example "page/13/to_be_or_not" I think exp is 12 and exp2 is to_be_or not.


 and the url is "/page/13/to_be_or_not", then handler would be called with "to_be_or_not" as its first parameter
 I think 12 as its first parameter.
why did you say to_be_or_not as its first parameter? I do not know why?

The key /number - starts searching from root of the application, and number starts searching from current
location.

 Subject: [Cppcms-users] question about mapper
  
 
 In the url_mapping example, the mapping is done with the following code:
        mapper().assign("number","/number/{1}");
Here the key is "number".

Later, a url is constructed with: url("/number",1)
Here the key is "/number".


My question is that why the key parameter passed to url(...) is
"/number" not "number"?


Thanks in advance.


Best regards.
