Problem using httpclient module in avalonia ios or xamarin forms ios projects #6476
Answer

Hello, I have solved it while i am preparing a minimal project :) Sometimes it is better to create it from scratch. Here is my findings and some questions if you can answer. I can also send the sample test project if you do not understand the questions just let me know.

So my problem was with the namespace. When i expose my services from the module i create "Controller" folder under httpapi project then set all folders under it here is a screenshot from my folder structure.

so i was trying to inject the isampleappservice from the application service namespace instead of controller namespace. And static generation is creating the isampleappservice for the controller namespace.

So the first question is if do not put my controller class under controller folder and namespace, it becomes ambiguous namespace for isampleappservice. Cause it is gonna be two isampleappservice comes from application.contracts and from generated folder. How can you fix that? Second question is about "With Contracts and Without Contracts" (https://docs.abp.io/en/abp/latest/API/Static-CSharp-API-Clients#client-proxy-generation) if i create my proxies without contracts first problem is solved. But i want to know downsides of it. Why isampleappservice is created at the first place with contracts? isn't the project referencing to application.contracts anyway? when you create your proxies "with contracts" then shouldn't you reference to application.contracts project? if you do not reference it, as i see it, it doesn't generate the dtos? how it is gonna be functional then?

As you can see i am little bit confused how should it be used. I want to create a nuget package that can be shared on my private repository since different ui platforms needs to access the backend. Any advice to do that? with or without contracts?

Problem using httpclient module in avalonia ios or xamarin forms ios projects #6476
Answer

one more thing about the problem. My HttpApi Client module consists of multiple HttpApi Client modules. After i posted the previous message, i have tried with only one of them, then the exception go away, but this time i got another exception message. "no service for type IScreenAppService has been registered". So somehow it can not get the service from ioc container. But i can see the generated service. I couldn't understand what i am doing wrong.

Problem using httpclient module in avalonia ios or xamarin forms ios projects #6476
Answer

Hello i changed the client module to static api but i am getting the same error. And the exception is the same. Do i do sth wrong over here? Is there any specific config that i need to do? To state the app that i use static proxies? Here is an overview of what i have done.

you can see the folder structure here for static proxies.

here is the client module code.

Problem using httpclient module in avalonia ios or xamarin forms ios projects #6476
Question
  • ABP Framework version: v8.0.0
  • UI Type: Angular
  • Database System: EF Core (PostgreSQL)
  • Tiered (for MVC) or Auth Server Separated (for Angular): yes

Hello, The question is related with Abp Client Proxies. I have a web server which uses abp and abp endpoints. Now i want to share the httpclient module of the web server and use it in avalonia ui project. I created an abp module and do necessary configurations for avalonia project. Added HttpClient project reference. Now when i run the project on android environment it works fine. But when i run it on ios, it throws an exception "platform not supported exception". here is the full exception

so the reason is obvious from the stacktrace. According to microsoft docs for ios, it says:

Since the iOS kernel prevents an application from generating code dynamically, Xamarin.iOS does not support any form of dynamic code generation. These include:

The System.Reflection.Emit is not available.
No support for System.Runtime.Remoting.
No support for creating types dynamically (no Type.GetType ("MyType`1")), although looking up existing types (Type.GetType ("System.String") for example, works just fine).
Reverse callbacks must be registered with the runtime at compile time.

I also find a previous post related with this https://support.abp.io/QA/Questions/2752/SystemPlatformNotSupportedException-when-running-Xamarin-Forms-on-iOS-using-ABP-Module-with-Autofac

so the question is, is it possible to make this work so i can use the httpclient module for my avalonia ios project? And I wonder how does this work for Maui App if it does not support System.Reflection.Emit. It seems like Castle.DynamicProxy class calls System.Reflection.Emit. Is Maui project bypassing this by replacing the service with sth else?

Abp v8 preview rc2 upgrade maui antiforgery token problem #6271
Answer

Hello, Thanks for the solution. I wonder two things.

  • Is the bug related to backend or is it because assigning a xsrf token to header while sending from the maui client? Probably the latter. Cause i replace the AbpAutoValidateAntiforgeryTokenAuthorizationFilter class it always come with xsrf token when i do a post from maui client.
  • How can i see the source code of Volo.Abp.Maui.Client package?

Also if i want to intercept the http requests, what is the correct way to do it in Maui Project? Let's say i want to add extra header for specific request. I tried sth like this but this doesn't work.

[Volo.Abp.DependencyInjection.Dependency(ReplaceServices = true)]
[ExposeServices(typeof(DynamicHttpProxyInterceptorClientProxy<IIdentityUserAppService>))]
public class IdentityUserAppServiceHttpProxyInterceptorClientProxy : DynamicHttpProxyInterceptorClientProxy<IIdentityUserAppService>
{
    protected override void AddHeaders(IReadOnlyDictionary<string, object> argumentsDictionary, ActionApiDescriptionModel action,
        HttpRequestMessage requestMessage, ApiVersionInfo apiVersion)
    {
        base.AddHeaders(argumentsDictionary, action, requestMessage, apiVersion);
        
    }

    protected override Task<HttpContent> RequestAsync(ClientProxyRequestContext requestContext)
    {
        return base.RequestAsync(requestContext);
    }
}
Abp v8 preview rc2 upgrade maui antiforgery token problem #6271
Question
  • ABP Framework version: v8.0.0 rc2
  • UI Type: Maui
  • Database System: EF Core (PostgreSQL)
  • Tiered (for MVC) or Auth Server Separated (for Angular): yes

Hello I am having problem with maui application when i do posts to the api. HttpStatusCode:400 returns every time, is sth changed on antiforgery token middleware on version 8? I didn't have this problem on v7.4. To reproduce the problem just create a new project from scratch with v8 rc2. abp new BookStore -t app-pro -u angular -dbms PostgreSQL --separate-auth-server -m maui -csf --preview then try to run maui app and **create a new user **(or try to do any post or put). you will get an error. Bad Request with status code 400

is there a way to ignore antiforgery token check for mobile app calls only.

Abp Cli switch-to-preview gives an error. #6248
Answer

Hello again, I understand why now. i switch to mac, that's why it appears in my solution. Cause $(UserProfile) env variable not exists on mac. env variable is $(HOME) instead. I think you should use this instead on common.props file. $([System.Environment]::GetFolderPath(SpecialFolder.UserProfile))

so you can support for each operating system. check this issue. https://github.com/dotnet/msbuild/issues/3908

Hello again, new updates from me. Now i fixed everything that i wanted. It was little struggle though. I will write here what I have done.

  • As you mentioned on the previous post. you have added remove borders classes from all platforms for entry,picker and datepicker. On the top of that (cause what i want is to have a bottom border) i have added some styles to Styles.xaml.

<Style TargetType="BoxView" x:Key="InputSeparator"> <Setter Property="Margin" Value="{OnPlatform Android='0,0,0,0',iOS='0,10,0,0',MacCatalyst='0,10,0,0'}"></Setter> <Setter Property="HeightRequest" Value="1"> </Setter> <Setter Property="HorizontalOptions" Value="Fill"></Setter> </Style>

&lt;Style TargetType=&quot;Label&quot; x:Key=&quot;InputLabel&quot;&gt;
   &lt;Setter Property=&quot;Margin&quot; Value=&quot;{OnPlatform iOS=&#39;0,0,0,5&#39;,MacCatalyst=&#39;0,0,0,5&#39;}&quot;&gt;&lt;/Setter&gt;
&lt;/Style&gt;

Then i have added those styles to label and entries for form elements. As an example:

as a result i got some border at the end for both android and ios.

  • Second issue was with checkbox on ios. there was no margin, so i added this style on the checkbox.
  • Third issue as i have mentioned before it was getting black textcolor when the edit page is requested on dark theme. This was an issue related with async void. For ex: on TenantEditModal, this was the method that has been called when edit has been clicked.
async partial void OnIdChanged(string? value)

This was causing threading problems i guess. So probably changing color was not invoked. so what i did instead is use AsyncHelper and leave the method as sync. Here is the code.

partial void OnIdChanged(string? value)
    {
        IsBusy = true;
        AsyncHelper.RunSync(GetTenant);
        AsyncHelper.RunSync(GetEditions);
        IsBusy = false;
    }

i have seen some people are using async void but according to me it is not the best practice.From my experience, it always bring some problems with it. The same problem exists on WeakReferenceMessenger. I have changed the code over there also. So i have been able to get the user interface that i wanted. here is how it looks at the end. Thanks for the code that has been provided by the way, it helped me a lot. On the other hand what i think is, on the long run adding RemovingHandlers to the project can be problematic in some cases. But for now it is good to go.

.Net Maui App Bugs, Especially on ios #6236
Answer

Hello thanks for the feedback, I have also started to fix the things one by one.

  • problem with empty image on ios comes from refreshview. there was an open issue for it. https://github.com/dotnet/maui/issues/7315 i think they fix that with .net 8. to overcome the problem you can wrap the collectionview with grid sth like this. then you don't need to change the width request. everything works fine.
  • for the borders on entry i think your code is removing all the borders, however i like the android style with border bottom. IOS doesn't support that though as i understand. Maybe i need to remove the frames i am not so sure about it. I will find sth for it.
  • I couldn't find the radiobutton fix while i was trying different variations, so i was planning to switch to another component so it is nice that you share it with me i can use it.

I have also upgraded my app to .net 8 yesterday, some things have been fixed however still some problems persist and some new problems arrived.

I will write over here if i can fix those things that i mention

Also worth to mention, I tried this .net 7, on list pages, maybe it has been fixed on .net 8 i didn't try

<RefreshView Grid.Row="1" IsRefreshing="{Binding IsBusy}" Command="{Binding RefreshCommand}">

this code makes the RefreshCommand triggers on the page load. since page appearing is also triggering the same code you call the endpoint twice. There was a discussion about it also in .net maui github issues. To overcome the situation, what i did was to bind RefreshCommand.IsRunning property instead of IsBusy. The reason behind this issue is when you call RefreshCommand it also sets the IsBusy property to true then it triggers the RefreshCommand again. new code is sth similar like this in my case.

<RefreshView Grid.Row="1" IsRefreshing="{Binding RefreshCommand.IsRunning}" Command="{Binding RefreshCommand}">
