IIS module and C#: how to modify the page content before sending it to client

由 杀马特。学长 韩版系。学妹 提交于 2019-12-09 21:13:11
问题 I am new to the IIS module and C# area. I need to modify the content of static HTML files in a specific directory of a website before the website sends the page content to client. The modification includes adding the banner, footer, etc. Based on my research, I should be able to achieve my goal through IIS Module (correct?). Here is my code: namespace MyProject { public class MyModule : IHttpModule { #region IHttpModule Members public void Dispose() { } public void Init(HttpApplication

Is this called adapter? + adapter vs decorator

由 半腔热情 提交于 2019-12-09 18:36:12
问题 I have 2 projects: A and B that should interactwith each other. Project A introduce interface names ISpecialTask and Project B should implement it. Projet B has an entity named TaskWithListOfProperties that cannot implement ISpecialTask because it has different structure of properties (in addition, all the system knows how to work with TaskWithListOfProperties and I don't want to change its structure). So I decided to create a class named SpecialTaskFromListOfProperties that implements

Java: Delegation Pattern and Protected Methods

由 大兔子大兔子 提交于 2019-12-09 18:21:28
问题 I have been using delegation pattern to wrap an object created by a factory in a 3rd party library. Recently, the library added a protected method in the base class and my wrapper class doesn't work any longer. Does anyone have a good solution without resorting to reflection? This is in 3rd party library and in their package, public class Base { public void foo(); protected void bar(); // Newly added } This is in my own package, public class MyWrapper extends Base { private Base delegate;

Decorating ASP.NET Web API IHttpController

由 感情迁移 提交于 2019-12-09 16:43:16
问题 I'm trying to wrap Web API controllers ( IHttpController implementations) with decorators, but when I do this, Web API throws an exception, because somehow it is expecting the actual implementation. Applying decorators to controllers is a trick I successfully apply to MVC controllers and I obviously like to do the same in Web API. I created a custom IHttpControllerActivator that allows resolving decorated IHttpController implementations. Here's a stripped implementation: public class

Python dynamic decorators - why so many wraps?

由 霸气de小男生 提交于 2019-12-09 14:38:39
问题 So I'm still kind of new to Python decorators - I've used them before, but I've never made my own. I'm reading this tutorial (that particular paragraph) and I don't seem to understand why do we need three levels of functions? Why can't we do something like this: def decorator(func, *args, **kwargs): return func(*args,**kwargs) Thanks :) 回答1: Well, what would happen if you called that decorator on a function? @decorator def foo(): pass This code would immediately call foo, which we don't want.

Decorate methods per instance in Python

由 ε祈祈猫儿з 提交于 2019-12-09 13:00:02
问题 Assume I have some simple class class TestClass: def doSomething(self): print 'Did something' I would like to decorate the doSomething method, for example to count the number of calls class SimpleDecorator(object): def __init__(self,func): self.func=func self.count=0 def __get__(self,obj,objtype=None): return MethodType(self,obj,objtype) def __call__(self,*args,**kwargs): self.count+=1 return self.func(*args,**kwargs) Now this counts the number of calls to the decorated method, however I

How does this Python decorator work?

问题 I was looking at some lazy loading property decorators in Python and happened across this example (http://code.activestate.com/recipes/363602-lazy-property-evaluation/): class Lazy(object): def __init__(self, calculate_function): self._calculate = calculate_function def __get__(self, obj, _=None): if obj is None: return self value = self._calculate(obj) setattr(obj, self._calculate.func_name, value) return value # Sample use: class SomeClass(object): @Lazy def someprop(self): print 'Actually

Is there an established memoize on-disk decorator for python?

由 青春壹個敷衍的年華 提交于 2019-12-09 06:49:55
问题 I have been searching a bit for a python module that offers a memoize decorator with the following capabilities: Stores cache on disk to be reused among subsequent program runs. Works for any pickle-able arguments, most importantly numpy arrays. (Bonus) checks whether arguments are mutated in function calls. I found a few small code snippets for this task and could probably implement one myself, but I would prefer having an established package for this task. I also found incpy, but that does

How to create a vector of all decorated functions from a specific module?

由 99封情书 提交于 2019-12-09 06:07:29
I have a file main.rs and a file rule.rs . I want to define functions in rule.rs to be included in the Rules::rule vector without having to push them one by one. I'd prefer a loop to push them. main.rs : struct Rules { rule: Vec<fn(arg: &Arg) -> bool>, } impl Rules { fn validate_incomplete(self, arg: &Arg) -> bool { // iterate through all constraints and evaluate, if false return and stop for constraint in self.incomplete_rule_constraints.iter() { if !constraint(&arg) { return false; } } true } } rule.rs : pub fn test_constraint1(arg: &Arg) -> bool { arg.last_element().total() < 29500 } pub fn
