I've created a service and injected it in singleton way inside my ViewModel, Service:

public Tive6Service()
    {
        _httpClient = new HttpClient();
    }

    public async Task<IEnumerable<WpPost>> GetAllWpPostsAsync()
    {            
        try
        {
            var response = await _httpClient.GetAsync(UriString + "/wp/v2/posts");
            if (response.IsSuccessStatusCode)
            {
                posts = await response.Content.ReadFromJsonAsync<IEnumerable<WpPost>>();
            }
            
        }
        catch (Exception e)
        {
            await Shell.Current.DisplayAlert("Error", e.Message, "Cancel");
        }
        return posts;
    }

    public async Task<WpPost> GetPostAsync(int id)
    {
        try
        {
            var response = await _httpClient.GetAsync(UriString + "/wp/v2/posts"+ id.ToString());
            if (response.IsSuccessStatusCode)
            {
                post = await response.Content.ReadFromJsonAsync<WpPost>();
            }

        }
        catch (Exception e)
        {
            await Shell.Current.DisplayAlert("Error", e.Message, "Cancel");
        }
        return post;
    }

ViewModel:

   public NewsViewModel(Tive6Service tive6Service)
    {
        Tive6Service = tive6Service;
        LoadPosts();
       
    }

    Task<ObservableCollection<WpPost>> LoadPosts()
    {            
        posts = new ObservableCollection<WpPost>(Tive6Service.GetAllWpPostsAsync().Result);
        return Task.FromResult(posts);  
    }

But during Debug the application stuck in the thread for recover all the WpPost, without throwing exceptions. Deepen in details, using method

post = await response.Content.ReadAsStringAsync();

it works, so the Web Api of the website are ok, like its swagger show me before that. What and where I'm wrong?

Thanks for your kindness

Answer 1

I've fixed the problem changing the line of code below in Service class:

var response = _httpClient.GetAsync(UriString + "/wp/v2/posts").Result;

Now it works. Thanks to everyone.
