C# WEBApi MVC Help pages



I have a custom route below and action.


[System.Web.Mvc.Route("Sites/id:string/Cache")]
public ResponseMessage<Result> DeleteCache ([FromUri] string id)
{



and when I got the the help page it gives three examples to use this call:


DELETE Sites/id/Cache
DELETE Sites/id
DELETE api/Sites/DeleteCache?id=id



I'd like to keep the first one and remove the others. Is there a built in way to do this?



Here is my WebApiConfig.cs snippit....


config.Routes.MapHttpRoute(
name: "DeleteCache",
routeTemplate: "controller/id/Cache",
defaults: new controller = "Sites", action = "DeleteCache"
);

config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "controller/id",
defaults: new id = RouteParameter.Optional
);





What do you mean by "help page"? Is that a page you wrote or something generated (like from Swagger)?

@AntoOne Yes, you can see my routes above now.

Are you sure that those other two routes trigger your action? They don't look related at all.

HelpPage will list every valid route for each controller. If you want a route to not apply to a specific controller you have to add contraints to the route to make it not match anymore :


config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "controller/id",
defaults: new id = RouteParameter.Optional ,
constraints: new controller = "((?!Sites).)*"
);



This uses a negative lookahead regex to match every Controllers not named Sites





Thanks for this, it appears to work opposite of what I want. I want DELETE Sites/id/Cache to remain while removing the other two, it did the reverse though it is a lead to track down. If you can fix this I'll mark it as accepted answer. Lets see who fixes it first, you or I. :)

DELETE Sites/id/Cache





I was able to add constraints: new controller = @"^(?:(?!Sites).)*$" to remove a few.

constraints: new controller = @"^(?:(?!Sites).)*$"

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Dynamically update html content plain JS

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
