I have VB.NET project and I created a WCF web service. I had the service added using Services References but then had a problem with a contract mismatch or something which I couldn't figure out so I decided to delete the service reference, rebuild the service code and add the service reference back. But now I am getting this error:
There was an error downloading blah.
The request failed with the error message:

Metadata contains a reference that cannot be resolved: blah.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
I am wondering whether the problem is with the .svc file which has:
<%# ServiceHost Language="VB" Debug="true" Service="InventoryExpressService.Service1" CodeBehind="InventoryExpress.svc.vb" %>
Where does it get the name "Service1" from? I can't find it anywhere else in my solution. That might be a red herring though. Any idea what might be going on? Thanks.

I'm building my website with Flutter but programming for web is very new to me and I'm not quite sure I understand exactly how Cookies work.
I still need to understand what cookies are to be written where, and where do I take those cookies from.
Building the banner to manage the should be easy, and if I'm not wrong it should be the first thing that pops up in the home page.
For example Medium banner is just a dismissible banner swing the message
To make Medium work, we log user data. By using Medium, you agree to our Privacy Policy.
with a link the Privacy Policy, but it doesn't have any opt-in so it doesn't look GDPR compliant..
Here https://medium.com/#mayur_solanki/flutter-web-formerly-hummingbird-ba52f5135fb0 shows how cookies are written and read in flutter web
html.window.localStorage['key']
html.window.sessionStorage['key']
html.window.document.cookie
html.window.localStorage['local_value'] = localStorage;
html.window.sessionStorage['session_value'] = sessionStorage;
html.window.document.cookie= "username=${cookies}; expires=Thu, 18 Dec 2020 12:00:00 UTC";
As far as I understood cookies are of these types.
First-party:
To track user behavior( page visits , number of users etc..) and as I use google Analytics I do need to ask consent for these.
here Google Analytics, Flutter, cookies and the General Data Protection Regulation (GDPR) is shown how to activate/deactivate it, so I shouldn't store anything myself if I'm not wrong.
Third-party:
These would be from a YouTube linked video on my Home page for example, so I need to ask consent for these too.
Haven't checked it yet but I guess it should be similar to Google Analytics
Session cookies:
These should be used to remember Items in a shopping basket.
I shouldn't be needing these..
Persistent cookies:
These should be for keeping user's logged in.
One of the web pages is the Retailer access, which is retailer's app (the supply side of the marketplace ).
I'm using Google signing to log in users, so I should be needing these, as the login form it always presented to users when navigating to Retailer access even after they logged in.
Secure cookies:
These are for https only and used for check-out/payment pages.
In my web the retailer's app only creates products, manages workshop bookings, and handles communication with customers..
The mobile app (the demand side of the marketplace) is where all the payments are made using Stripe, so I shouldn't have to store anything on web..right?
Sorry for the long question, I hope it's clear enough.
Thank you for your help.
I basically had the problem since I am also using third-party scripts (firebase, stripe, ...) and I need the user's consent before any of those scripts are run.
I build my solution around Yett (https://github.com/elbywan/yett), which blocks scripts that are part of a previously defined blacklist. You could even implement this functionality by yourself, the author has written an interesting medium article.
In my case I only have "essential" scripts, so I built a solution where the flutter app loads only if the user consented to the all necessary scripts. But it shouldn't be too difficult to adjust this solution if one needs more fined grained control about the user's cookie settings and I added a second entry for "Analytics" as a possible starting point.
I store the user's settings in the localStorage and retrieve them directly on app start to create the blacklist and to decide whether the cookie banner should be shown.
This is my index.html.
It references the following scripts: get_consent.js, set_consent.js, init_firebase.js and load_app.js (more info on them below).

The get_consent.js is the first script, retrieves the user's settings from localStorage and also defines the yett blacklist:
const essentialCookies = ["js.stripe.com", "www.gstatic.com"];
const analyticsCookies = ["www.google-analytics.com"];
const allCookies = [...essentialCookies, ...analyticsCookies];
const consentPropertyName = "cookie_consent";
const retrieveConsentSettings = () => {
const consentJsonString = localStorage.getItem(consentPropertyName);
return JSON.parse(consentJsonString);
};
const checkConsentIsMissing = () => {
const consentObj = retrieveConsentSettings();
if (!consentObj || consentObj.length == 0) {
return true;
}
return false;
};
const consentIsMissing = checkConsentIsMissing();
var blacklist;
if (consentIsMissing) {
blacklist = allCookies;
} else {
const acceptedCookies = retrieveConsentSettings();
// Remove all script urls from blacklist that the user accepts (if all are accepted the blacklist will be empty)
blacklist = allCookies.filter( ( el ) => !acceptedCookies.includes( el ) );
}
// Yett blacklist expects list of RegExp objects
var blacklistRegEx = [];
for (let index = 0; index < blacklist.length; index++) {
const regExp = new RegExp(blacklist[index]);
blacklistRegEx.push(regExp);
}
YETT_BLACKLIST = blacklistRegEx;
set_consent.js is responsible for updating localStorage with the user's settings and also hides/shows the respective divs for the cookie consent. Usually, one could simply call window.yett.unblock() to unblock the scripts, but since their order matters I decided to simply reload the window after the localStorage was updated:
const saveToStorage = (acceptedCookies) => {
const jsonString = JSON.stringify(acceptedCookies);
localStorage.setItem(consentPropertyName, jsonString);
};
window.onload = () => {
const consentPopup = document.getElementById("consent-popup");
const consentPopupDetails = document.getElementById("consent-popup-details");
const acceptBtn = document.getElementById("accept-btn");
const moreInfoBtn = document.getElementById("info-btn");
const saveBtn = document.getElementById("save-btn");
const cancelBtn = document.getElementById("cancel-btn");
const rejectBtn = document.getElementById("reject-btn");
const acceptFn = (event) => {
const cookiesTmp = [...essentialCookies, ...analyticsCookies];
saveToStorage(cookiesTmp);
// Reload window after localStorage was updated.
// The blacklist will then only contain items the user has not yet consented to.
window.location.reload();
};
const cancelFn = (event) => {
consentPopup.classList.remove("hidden");
consentPopupDetails.classList.add("hidden");
};
const rejectFn = (event) => {
console.log("Rejected!");
// Possible To-Do: Show placeholder content if even essential scripts are rejected.
};
const showDetailsFn = () => {
consentPopup.classList.add("hidden");
consentPopupDetails.classList.remove("hidden");
};
const saveFn = (event) => {
const analyticsChecked = document.getElementById("analytics-cb").checked;
var cookiesTmp = [...essentialCookies];
if (analyticsChecked) {
cookiesTmp.push(...analyticsCookies);
}
saveToStorage(cookiesTmp);
// Reload window after localStorage was updated.
// The blacklist will then only contain items the user has not yet consented to.
window.location.reload();
};
acceptBtn.addEventListener("click", acceptFn);
moreInfoBtn.addEventListener("click", showDetailsFn);
saveBtn.addEventListener("click", saveFn);
cancelBtn.addEventListener("click", cancelFn);
rejectBtn.addEventListener("click", rejectFn);
if (consentIsMissing) {
consentPopup.classList.remove("hidden");
}
};
init_firebase.js is the usual script for initializing the service, but I only inizialize if consent was obtained:
var firebaseConfig = {
// your standard config
};
// Initialize Firebase only if user consented
if (!consentIsMissing) {
firebase.initializeApp(firebaseConfig);
}
The same logic is applied to the script load_app.js. The Flutter app is only loaded if the user consented.
One might therefore add some fallback content to the index.html which would be shown if the user rejects the necessary scripts. Depending on your use case it might also be an option load the app anyway and then differentiate within the app by accessing the user's settings from localStorage.
var serviceWorkerVersion = null;
var scriptLoaded = false;
function loadMainDartJs() {
if (scriptLoaded) {
return;
}
scriptLoaded = true;
var scriptTag = document.createElement("script");
scriptTag.src = "main.dart.js";
scriptTag.type = "application/javascript";
document.body.append(scriptTag);
}
// Load app only if user consented
if (!consentIsMissing) {
if ("serviceWorker" in navigator) {
// Service workers are supported. Use them.
window.addEventListener("load", function () {
// Wait for registration to finish before dropping the <script> tag.
// Otherwise, the browser will load the script multiple times,
// potentially different versions.
var serviceWorkerUrl =
"flutter_service_worker.js?v=" + serviceWorkerVersion;
navigator.serviceWorker.register(serviceWorkerUrl).then((reg) => {
function waitForActivation(serviceWorker) {
serviceWorker.addEventListener("statechange", () => {
if (serviceWorker.state == "activated") {
console.log("Installed new service worker.");
loadMainDartJs();
}
});
}
if (!reg.active && (reg.installing || reg.waiting)) {
// No active web worker and we have installed or are installing
// one for the first time. Simply wait for it to activate.
waitForActivation(reg.installing ?? reg.waiting);
} else if (!reg.active.scriptURL.endsWith(serviceWorkerVersion)) {
// When the app updates the serviceWorkerVersion changes, so we
// need to ask the service worker to update.
console.log("New service worker available.");
reg.update();
waitForActivation(reg.installing);
} else {
// Existing service worker is still good.
console.log("Loading app from service worker.");
loadMainDartJs();
}
});
// If service worker doesn't succeed in a reasonable amount of time,
// fallback to plaint <script> tag.
setTimeout(() => {
if (!scriptLoaded) {
console.warn(
"Failed to load app from service worker. Falling back to plain <script> tag."
);
loadMainDartJs();
}
}, 4000);
});
} else {
// Service workers not supported. Just drop the <script> tag.
loadMainDartJs();
}
}

I created an API with WSO2 API Manager adding my own java Restful Service as Endpoint. Testing the service endpoint worked fine.
I subscribed to the API properly but when invoking the API with the swagger it returns the following body content:

An application/xml media type is supposed to be returned!
Here is the screen shot of my swagger after calling the api
Here is the response when calling the service directly from the browser
I have also changed the response media type to application/json but it still did'nt worked too.
Can someone please help me to fix this problem?
The issue is you have message part at the end of both endpoint and actual request. That makes the underneath call becomes
http://localhost:8080/messanger/webapi/messages/messages/
which is an invalid URL.
The solution is simple. Remove the messages part from the endpoint URL.
i.e. Endpoint URL should be http://localhost:8080/messanger/webapi/
I try to get working the electron-vue boilerplate. After setting up the project everything works, but as I create a new .vue file (TopMenu.vue) I get:
vue.common.js?4eb4:2569 [Vue warn]: Unknown custom element: <topmenu> -
did you register the component correctly? For recursive components, make
sure to provide the "name" option. (found in component <landing-page>)
I use the exact syntax as the original .vue files which came with the boilerplate:
LandingPageVue.vue:
<style scoped>
img {
margin-top: -25px;
width: 450px;
}
</style>
<template>
<div>
<!-- <img src="./LandingPageView/assets/logo.png" alt="electron-vue"> -->
<h1>Welcome.</h1>
<topmenu></topmenu>
<current-page></current-page>
<versions></versions>
<links></links>
<div class="container">
</div>
</template>
<script>
import TopMenu from './LandingPageView/TopMenu'
import CurrentPage from './LandingPageView/CurrentPage'
import Links from './LandingPageView/Links'
import Versions from './LandingPageView/Versions'
export default {
components: {
TopMenu,
CurrentPage,
Links,
Versions
},
name: 'landing-page'
}
</script>
TopMenu.vue (my file):
<template>
<p>
TOPMENU
</p>
</template>
By the way, how the hack does <current-page></current-page> work (notice the "-" dash) if bellow it is declared without?
It's not working because you're not exporting anything in your vue file.
Try this in your TopMenu.vue file:
<template>
<p>
TOPMENU
</p>
</template>
<script>
export default {
}
</script>
Also change the html <topmenu></topmenu> to <top-menu></top-menu>
For your second question, HTML is case insensitive so your title case components wouldn't match with html tags. So Vue translates your title case components to a 'dash-case'.
From the documentation itself there's the explanation why:
Note that Vue does not enforce the W3C rules for custom tag names (all-lowercase, must contain a hyphen) though following this convention is considered good practice.

I'm very new to Grails but have been using Ruby on Rails for the past few months, I can't seem to get my head around how to correctly Mock some functionality within a Service I have so I can properly Unit Test it.
I have a RestService which uses a RestBuilder plugin
import javax.persistence.Converter;
import org.codehaus.groovy.grails.web.json.JSONArray
import org.json.JSONObject
import grails.converters.JSON
import grails.plugins.rest.client.RestBuilder
import grails.transaction.Transactional
#Transactional
class RestService {
def retrieveFromRESTClient(url) {
System.properties.putAll( ["http.proxyHost":"some.proxy.host.com", "http.proxyPort":"8080", "https.proxyHost":"some.proxy.host.com", "https.proxyPort":"8080"] )
def restBuilder = new RestBuilder()
def clientResponse = restBuilder.get(url)
// For development purposes
print "retrieveFromRESTClient: " + clientResponse.json
return clientResponse
}
}
I'm attempting to write a Unit Test for retrieveFromRESTClient() and my thoughts are I should be Mocking the restBuilder.get() plugin call so it doesn't go off and actually do a get request to a URL during the Test. I've attempted a few things already such as extracting the plugin functionality to it's own method:
def retrieveFromRESTClient(url) {
System.properties.putAll( ["http.proxyHost":"some.proxy.host.com", "http.proxyPort":"8080", "https.proxyHost":"some.proxy.host.com", "https.proxyPort":"8080"] )
def clientResponse = getResponse(url)
// For development purposes
print "retrieveFromRESTClient: " + clientResponse.json
return clientResponse
}
def getResponse(url) {
def restBuilder = new RestBuilder()
def resp = restBuilder.get(url)
resp
}
and in my RestServiceSpec attempting to mock getResponse
import org.springframework.http.ResponseEntity;
import grails.plugins.rest.client.RestBuilder;
import grails.test.mixin.TestFor
import groovy.mock.interceptor.MockFor
import spock.lang.Specification
#TestFor(RestService)
class RestServiceSpec extends Specification {
def cleanup() {
}
void "retrieveFromRESTClient's responses JSON can be accessed"() {
when:
service.metaClass.getResponse { ResponseEntity<String> foo -> return new ResponseEntity(OK) }
def resp = service.retrieveFromRESTClient("http://mocking.so.it.doesnt.matter/")
then:
print resp.dump()
assert resp.json == [:]
}
}
Although this test passes, when I look at resp.dump() in the test-reports I see it's still gone and made a request to 'mocking.so.it.doesnt.matter' and returned that object instead of the mocked ResponseEntity which I assumed it would return.
test-report output:

My end goal is to bypass the plugins get call and return a ResponseEntity object. I'm not really sure if I'm using the correct approach for this?
In your unit test, you mocked a method that is expecting a
ResponseEntity<String> foo
as parameter.
But then you call :
service.retrieveFromRESTClient("http://mocking.so.it.doesnt.matter/")
with a parameter type of String. So your mocked method is not being called (method signatures differs).
Change your mocked method to :
service.metaClass.getResponse { String foo -> return new ResponseEntity(OK) }
and it should work.
ItemCommand contains RepeaterCommandEventArgs which has two important fields:
CommandName
CommandArgument
how to get Button event,get asp:DropDownList select values
<asp:FormView runat="server" id="fwHotelDetails" DataKeyNames="id" OnDataBound="fwHotelDetails_DataBound" OnModeChanging="fwHotelDetails_ModeChanging" >
<ItemTemplate>
<asp:Repeater runat="server" id="repScore">
<ItemTemplate>
<asp:DropDownList ID="ddlnumber" runat="server">
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
<asp:ListItem>3</asp:ListItem>
</asp:DropDownList>
<asp:LinkButton ID="saveButton" runat="server" CausesValidation="False" CommandName="Edit" CommandArgument='<%# Eval("id")%>' Text="Edit" />
</ItemTemplate>
</asp:Repeater>
<EditItemTemplate>
Test test, anything??
</EditItemTemplate>
</ItemTemplate>
</asp:FormView>
The RepeaterCommandEventArgs argument contains a property called Item. From this property you can access the method FindControl().
So your code would look like this:
void repScore_ItemCommand(Object sender, RepeaterCommandEventArgs e) {
DropDownList ddl = (DropDownList)e.Item.FindControl("ddlNumber");
string selectedValue = ddl.SelectedValue;
}
Also, don't forget to wire up your repeater to handle the event:
<asp:Repeater ... OnItemCommand="repScore_ItemCommand" .... >
