query-parameters

问题 I just initialized a Yesod project (no database) using yesod init . My HomeR GET handler looks like this: getHomeR :: Handler Html getHomeR = do (formWidget, formEnctype) <- generateFormPost sampleForm let submission = Nothing :: Maybe (FileInfo, Text) handlerName = "getHomeR" :: Text defaultLayout $ do aDomId <- newIdent setTitle "Welcome To Yesod!" $(widgetFile "homepage") When using yesod devel , I can access the default homepage at http://localhost:3000/ . How can I modify the handler

问题 According to Jersey documentation Filters can be used when you want to modify any request or response parameters like headers So I believe modifying query params is possible but I don't know how and I haven't been able to find anything on Google or stackoverflow... This the functionality I would like to achieve: public class EreturnLookupFilter implements ContainerRequestFilter { private static final Logger logger = Logger.getLogger(UserResource.class.getName()); @Override public void filter

问题 I am trying to get access to query parameters using Express in Node.js. For some reason, req.params keeps coming up as an empty object. Here is my code in server.js : const express = require('express'); const exphbs = require('express-handlebars'); const bodyParser = require('body-parser'); const https = require('https'); //custom packages .. //const config = require('./config'); const routes = require('./routes/routes'); const port = process.env.port || 3000; var app = express(); /

问题 I've built an angular 9 app, and added localization with @ngx-translate. I've configured my app so that it takes the lang query parameter and changes the locale accordingly. @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit, OnDestroy { constructor(private route: ActivatedRoute, private translateService: TranslateService) { this.translateService.setDefaultLang('en'); this.route

问题 I need to have my own error response body when something goes wrong with my request and I am trying to use the @NotEmpty constraint message attribute to return the error message, This is my class that returns the error message using the body that I need: package c.m.nanicolina.exceptions; import org.springframework.http.HttpStatus; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.MissingServletRequestParameterException; import org.springframework.web.bind

问题 Im navigating after building up a queryParams object with a form: options { ... words: (4) ["chuck", "norris", "vs", "keanu", "reeves"] } Then navigate with that object to update the URL's parameters: this.router.navigate(['/search'], { queryParams: options }); The URL words param is duplicated for each entry like this: /search?words=chuck&words=norris&words=vs&words=keanu&words=reeves How do we pass in an array to queryParams properly?

问题 I have a path as <Route path="/account/:accountid/LoginPage" component={LoginPage}/> This works fine if the url is -> /account/12332/LoginPage . I want to have optional query parameters. Url structure would be something as /account/12322/LoginPage?User=A&User=B I have modified the path as <Route path="/account/:accountid/LoginPage(/:User)" component={LoginPage}/> after this if I try to access the url it does not redirect me to the appropriate page instead it throws an error as useBasename.js

问题 I'm struggling with creating regex to match URL path with query param that could be in any place. For example URLs could be: /page?foo=bar&target=1&test=1 <- should match /page?target=1&test=2 <- should match /page/nested?foo=bar&target=1&test=1 <- should NOT match /page/nested?target=1&test=2 <- should NOT match /another-page?foo=bar&target=1&test=1 <- should NOT match /another-page?target=1&test=2 <- should NOT match where I need to target param target specifically on /page This regex works
