我可以在blazor中使用Autorest客戶端嗎?

asp.net-core autorest blazor c# mono

當我嘗試在webassembly上運行我的blazor應用程序時,我從mono平台獲得了System.PlatformNotSupportedException 。我使用Autorest自動生成了一個web api客戶端。一切都編譯得很好但是當我在瀏覽器中加載代碼時,我在瀏覽器控制台中收到以下錯誤。

使用VS2017的預覽版本。

熱門答案

對的,這是可能的。但是你必須使用由blazor框架注入的HttpClient,如下所述:

https://learn-blazor.com/architecture/rest-api/

(感謝弗洛雷斯的鏈接!)

HttpClient在Autorest使用的Microsoft.Rest.ServiceClient中標記為受保護。因此,要從blazor注入HttpClient,您可以創建自動生成的客戶端類的新部分並添加SetHttpClient方法:

autorest生成的類:

public partial class YourApi : ServiceClient<YourApi>, IYourApi
{
    ...
}

你的新部分:

public partial class YourApi
{
    public void SetHttpClient(HttpClient client) {
        this.HttpClient = client;
    }
}

好又簡單!
