parameters

问题 I'm trying to accessing two http request parameters in a Java Servlet filter, nothing new here, but was surprised to find that the parameters have already been consumed! Because of this, it is not available anymore in the filter chain. It seems that this only occurs when the parameters comes in a POST request body (a form submit, for example). Is there a way to read the parameters and NOT consume them? So far I've found only this reference: Servlet Filter using request.getParameter loses Form

问题 How to run a perl script from another passing parameters? I'm trying to use a solution found in a internet post that i can't find anymore. It was something like: do 'script.cgi param1 param2'; And in the other script I'm using simply the shift to get those parameters: #Parameters my $param1= shift; my $param2= shift; I saw people using system with args, but is it better for real? If not, how can I fix the solution with 'do EXPR'? Thanks in advance. 回答1: Oh well, I solved doing: {local @ARGV =

问题 I am trying to understand exactly what this line of code is, as I am learning C. int (*f) (float *) I know the first part is a pointer to an int named f, however the second part is what I am unsure of. Would this be classed as a pointer to an int named f which is cast to a pointer-to-float or Would this be a pointer named f, pointing to a function with a pointer parameter. Would be great if someone could help and possible explain why or the difference between the two as I am having a little

问题 I want to make a text-based fighting game, but in order to do so I need to use several functions and pass values around such as damage, weapons, and health. Please allow this code to be able to pass "weapons" "damage" "p1 n p2" throughout my code.

问题 In this case I want to pass _source_dir_abs:str into decorator. I tried to mimic the same process that Flask has for routing to pass parameter from decorator to function it is decorated. But this makes the parameter interpreted as a literal string and not as a variable. @dec_check_abs("<_source_dir_abs>") def walk_return_dir_nofolder(_source_dir_abs:str) -> list: w = walk(_source_dir_abs) d = [d for d, fol, fil in w if len(fol) == 0] return d I tried with @dec_check_abs(_source_dir_abs) it

问题 The parameter has yet to be setup, but it will be to determine what jobs to pull (Open, Soft Closed, Closed, or All). So, if the user says they want Open jobs to print, we want the section to suppress if ContractStatus<>Open. Any suggestions? 回答1: In the Section Expert, highlight the section you want to suppress. Next to Suppress click on the formula button (x-2). Do not check the Suppress box! Create a formula like: {tableName.ContractStatus} <> {?ParameterName} This will suppress the

问题 I'm wondering if this can be done at the parameter level rather in code: I have 2 parameter: $School and $Class Get-Students -School SchooName # Will give me all Students name in all classes in that School Get-Students -Class ClassName # Will give me all Students name in that Class across all schools Get-Students # Should return parameter level error.
