I'm trying to develop a simple webform application to create/edit invoice from a .aspx page and want to sync QB Desktop & MS SQL database using web connector & .ASMX web service (2 way sync: QBD -> web app & web app > QBD).
Here is a what I did:
I've setup QB Desktop US version 19 (latest) and Web connector
Added an application via adding .QWC file (I'm using this default .qwc file without any changes, not sure even how can I make it!!)
Step 1 & 2, are done but looking for proper solution to start with the development part. I've referred some other StackOverflow questions and found this sample but not sure which project and version I've to choose from both of them. I'm finding some good sample applications which connects to QB Desktop & Web applications using Interop.QBFC13
I really don't have idea how web connector works and sync with my web app.
Thanks!
I'm using this default .qwc file without any changes, not sure even how can I make it!!
This ^^^ will not work. Ever. There is no "default" .QWC file -- it is specific to your application and if you're using someone else's it's guaranteed not to work.
Create your own .QWC file. Example template:
<?xml version="1.0"?>
<QBWCXML>
<AppName>QuickBooks Integrator</AppName>
<AppID></AppID>
<AppURL>https://example.com/quickbooks/server.php</AppURL>
<AppDescription></AppDescription>
<AppSupport>https://example.com/quickbooks/support.php</AppSupport>
<UserName>username</UserName>
<OwnerID>{90A44FB7-33D9-4815-AC85-AC86A7E7D1EB}</OwnerID>
<FileID>{57F3B9B6-86F1-4FCC-B1FF-967DE1813D20}</FileID>
<QBType>QBFS</QBType>
<Scheduler>
<RunEveryNMinutes>2</RunEveryNMinutes>
</Scheduler>
<IsReadOnly>false</IsReadOnly>
</QBWCXML>
Fields:
<AppName> This is displayed to the user in the Web Connector GUI
<AppID></AppID> Leave it blank
<AppSupport>...</AppSupport> Must contain a valid URL to a valid page which returns a 200 OK HTTP response when visited. Users who have technical problems will be directed here.
<AppURL>...</AppURL> Must contain a valid URL to your SOAP server, https://... if it's remote, http://localhost/... if it's local.
<UserName>...</UserName> This will match the username your SOAP server understands for authentication
<FileID>...</FileID> You can make this up as long as it follows the GUID format (uppercase HEX chars only!): {6904A826-7368-11DC-8317-F7AD55D89593}. It has something to do with DataExt elements; most simple integrations can just make this up.
<OwnerID>...</OwnerID> Same as above
<QBType>...</QBType> Specifies the type of Quickbooks you want to connect to with the web connector (ie “QBFS” or “QBPOS”)
<Scheduler>...</Scheduler> This is an optional element, use this to schedule the Web Connector to run every so often automatically
<IsReadOnly>...</IsReadOnly> Leave this set to false, setting it to true will not work.
Did you read the 100+ page PDF that documents exactly how the Web Connector works and what you need to implement? Link:
QuickBooks Web Connector Programmer's Guide PDF
What have you tried to implement so far?
I have a new Web API developed in ASP.NET Core. This Web API is supposed to be deployed in IIS and will have to work over SSL, so I have the [HttpsRequired] attribute on all my controllers. I struggle to make it work while deployed, so for now I relaxed the requirements and commented out those attributes. Doing so, I was able to create two bindings in IIS, one for HTTPS and one for HTTP. Given that my Web API is created in ASP.NET Core, I followed the deployment steps Rick Strahl has in his excellent blog post. I have selected "No Managed Code" for the .NET CLR version. The IIS machine is a 64-bit Windows Server 2012 R2 environment - not sure whether this matters or not. The .NET Core Windows Server Hosting bundle has been installed on the server and I can see the AspNetCoreModule listed in the Modules grid.
If i try to access the Web Api (I created a very simple GET method that returns some information regarding the assembly) with Fiddler, I get a 404 error. For now, i run Fiddler on the same machine, so I tried all combinations (localhost, IP address and full machine name in the domain).
No errors are logged in the EventViewer. Does anyone have any suggestion on how to troubleshoot this issue?
TIA,
Eddie
EDIT1: Here is my controller:
[Route("api/info")]
//[RequireHttps]
public class InfoController : Controller
{
private ITncRepository _repository;
public static ApplicationAssemblyDetails ApplicationAssemblyDetails { get; set; }
public InfoController(ITncRepository repository)
{
_repository = repository;
ApplicationAssemblyDetails = ApplicationAssemblyDetails.Current;
}
[HttpGet("")]
public JsonResult Get()
{
return Json(new WebApiInfoModel()
{
CurrentTime = DateTime.Now,
CurrentUtcTime = DateTime.UtcNow,
AssemblyName = ApplicationAssemblyDetails.ApplicationAssembly.FullName,
VersionNumber = ApplicationAssemblyDetails.VersionNumber,
BinFolder = ApplicationAssemblyDetails.BinFolder,
BuildMode = ApplicationAssemblyDetails.BuildMode,
TradeMark = #" © 2016-2017 * SomeCompany (www.somecompany.com)"
});
}
}
The ApplicationAssemblyDetails is a nuget package that gives some info about the current assembly. WebApiInfoModel is my model class for the Web API Information I want to pass back as a test to the client.
The web.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\My_ASP_NET_Core_Web_API.exe" arguments="" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="true" />
</system.webServer>
</configuration>
Finally, to answer your last question, Ignas, I use a Publishing Profile that uses the File system as a method, targets the .NET Framework 4.5.2, using the release configuration. Given that my project is a Web API and not an MVC 6 Web Application, the publishing package creates a stand-alone application. Since the clients need to call my Web API using SSL, I think that it has to be hosted in IIS, so running the standalone application would not work. Of course, for testing purposes, I could try to run it. That's why I commented out the [HttpsRequired] attribute. I will try that and report back, but for now I hope I gave you all the information you required.
I'm having a setup very close to yours (Asp.Net core, Web API, IIS, HTTPS ...) working fine on my end.
I faced the same issue at some point because I was not using the proper path to access my controller/action, it depends on how you deployed it under IIS. For instance, in my case when I use Kestrel directly it goes through a URL like that:
http:// localhost:5000/controllerName/actionName
But I can also contact my Web API via IIS and in that case I need to use a URL like that:
http:// localhost:5001/applicationName/controllerName/actionName
Have you created an application under IIS that could explain you getting a 404 because you would not use the proper path?
For instance, in my case:
screenshot of the asp.net core api under iis
And I'm accessing it, through the URL:
https: //servername:serverport/RequestPortalAPI/ControllerName/ActionName
In the end, it was a matter of properly configuring Widows Authentication. For Fredrik and anyone else reading this post for a solution, these are the steps I performed:
In IIS, in the Authentication form for my Web API, I disabled Anonymous Authentication and I enabled Windows Authentication:
Make sure that "Negotiate" is at the top of the list for Enabled Providers:
In the Application Pools, I configured my Web API to run under an account that the UIT department of my client has given me:
The configuration file of my Web API (web.config) contains the following settings:
Now we are getting into the dark areas of the problem. In order to use Windows Authentication and let the credentials of the caller be passed through to the backend (in my case a SQL Server database), the Web API has to be configured to use Kerberos. I found this after I opened a ticket with Microsoft and I worked closely with one of their engineers. For this to happen, you need to follow these steps:
Create a Service Principal Name (SPN) for your Web API and the domain account it runs under. You need to run this command:
Where hostname is the fully qualified domain name of your Web API. The Domain\Username are the domain account under which the Web API is running. You need special domain privileges, so you may want to involve someone from IT. Also, from now on, you need to access your Web API by the full domain name, not by IP address. IP address won't work with Kerberos.
Also, with the help of your IT person, you need to enable delegation for any service using Kerberos for the domain account under which you run your Web API. In the Active Directory Users and Computers, locate the account you use to run your Web API, bring up its properties, click on the Delegation tab and enable the second option "Trust this user for delegation to any service (Kerberos Only):
We have also made some changes on the server that runs our database, but I am not 100% those are truly required, so I won't add them here because I don't even know if you use SQL Server or some other backend repository.
Let me know if you need those as well and I will add them later.
Good luck,
Eddie
I want to connect to microsoft dynamics CRM via tools or code, but every time I try I get this error :
the provided uri did not return any service endpoints
Also when I go to its discovery.svc link I get the following error :
An error has occurred.
Try this action again. If the problem continues, check the Microsoft Dynamics CRM Community for solutions or contact your organization's Microsoft Dynamics CRM Administrator. Finally, you can contact Microsoft Support.
I check the IIS binding and its just bind to 5555 for HTTP and 5556 for HTTPS and also the above error occur on server side too, I mean when I go to http://myAddress:5555/XRMServices/2011/Discovery.svc both in server and clients I get the error. I cant find any thing that could solve my problem in the internet and I'm stock in this simple problem for several days.
I think after I solved my problem this could be useful for somebody. There was two problem first my server has configuration problem and server needs restart to free its memory. so it's not bad if you check how memory you are using, and if its possible restart the server.
and after that I have a proxy problem that could be fix with creating a file name app.config and writing this lines:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy >
</defaultProxy>
</system.net>
</configuration>
Then it'll works fine
I have Create an Application in MVC which is currently using AWS Data Server.For it I am using Amazon Simple DB API . My Database Created by the client is allocated at US-EAST-1 but by the code it's accessing the Database US-WEST-2.
If I am Creating the Database or Table Pro grammatically by the code like-
simpleDBClient.CreateDomain(new CreateDomainRequest() { DomainName = "DemoTable"});
it also stores in US-WEST-2 Region.Please let me know how come i retrive the AWS US-EAST-1 Tables.
and in the starting I have also choosed the US-EAST-1 at the time of Creation of Project in Visual Studio. Any Help will be Appreciated.
Check out this blog post from the .NET team on using regions and the .NET SDK. In essence,if you are using V2 of the SDK you can modify you app.config or web.config to look like this:
<configuration>
<appSettings>
<add key="AWSRegion" value="us-east-1"/>
</appSettings>
</configuration>
I have a scenario where users are Uploading Transactions logs to Main Server Via ASMX Webservice. The application is clickonce .Net winforms app
Currently I am doing this To convert to List of Object to Json and Deserialize it on Service. over the SSL.
string data = JsonConvert.SerializeObject(Values_Static.logitems);
My Code is protected by SmartAssembly . And still I am getting some breach that attacker have access to the Network Connections and Can Deserliaze the Data.
Now i am thinking of a Scenario that I Encrypt the Json String with some private string key and then decypt it on the server .
e.g
private string salt = "$e7?8f#l4";
return ByteArrToString(Encrypt(TextValue + salt));
Hardcode the key in app and decode it in server.
will it work ?
Users are uploading the the logs to server every minute and there are possibly 20-30 entries per Upload.
is there any chances of broken Data or still the hacking ?
UPDATE :
According to Discussion Below . I understand that there is some issue with my Code. The code is accepting the invalid certificate . How i Can prevent to Accept only Valid Certificate from my https:// Web service .
ATM , every one can see the code through fiddler with Decryption HTTPS on .
I have a valid Certificate installed on my IIS 7. and its working properly
the issue is with code. and its standard auto generated web reference in Visual Studio.
UPDATE 2 :
The Final Result is , The Post data is not Encrypting , its Plain XML and readable by any software that can sniff , however the GET data is secure . I had serached bit not found some valid Answer.
Are you using SSL? If so, any application-level encryption is redundant. And, the key will have to be embedded in the code, so is readable by any attacker.
Fiddler (or other HTTPS proxies) can decrypt any HTTPS traffic.
You could prevent simple use of Fiddler by requiring a specific server certificate in your client code (rather than trusting any certificate the system itself trusts). However, this is only a weak deterrent because the user could just decompile your code and alter it so that your new certificate check is neutered.
This is called the "Untrusted client" problem, and it's the same thing that makes Digital Rights Management (DRM) software a "best effort" affair rather than an ironclad protection.
