To define the HttpClient
globally and avoid setting the HttpClientInstance property all over your
application, you can create a custom component that encapsulates the SfDataManager
and sets the HttpClient at a global level. Create a custom Blazor component
that wraps the SfDataManager and configures the HttpClient in its
OnInitializedAsync method.
|
@inherits
ComponentBase
@inject
IHttpClientFactory HttpClientFactory
@using
Syncfusion.Blazor.Data
@using Syncfusion.Blazor
<SfDataManager Url="api/Default" Adaptor="Adaptors.WebApiAdaptor" HttpClientInstance="httpClient" CrossDomain="true"></SfDataManager>
@code
{
private HttpClient httpClient;
protected override async Task
OnInitializedAsync()
{
httpClient = HttpClientFactory.CreateClient("WebAPI");
await base.OnInitializedAsync();
}
}
|
Register this custom component in your application:
In your _Imports.razor file, add
an import statement for the namespace where you define the custom component
(e.g., MyApp.Components):"
|
@using BlazorApp5.Client.MyComponent
|
Use the custom component wherever you need the SfDataManager that is
configured globally with the HttpClient.
|
<MyCustomSfDataManager></MyCustomSfDataManager>
|
With this approach, you only need to define the HttpClient configuration in
your Program.cs file once and then use the MyCustomSfDataManager component
throughout your application without specifying HttpClientInstance. This
encapsulates the HttpClient setup and makes your code cleaner and more
maintainable. For your reference, we have attached a modified sample.
