Question

尝试使用Postman将一些数据发布到ms sql服务器并测试我的api。我收到错误消息：

InvalidOperationException：无法解析类型的服务 “ Microsoft.AspNetCore.Identity.UserManager`1 [MyOrg.Models.User]”而尝试激活“ MyOrg.Controllers.AccountsController”。

我已经检查并尝试了几种类似问题的解决方案，但无济于事。

这是我的代码：

Startup.cs

    private String copyFiletoExternalStorage(int resourceId, String resourceName){
    String pathSDCard = Environment.getExternalStorageDirectory() + "/Android/data/" + resourceName;
    try{
        InputStream in = getResources().openRawResource(resourceId);
        FileOutputStream out = null;
        out = new FileOutputStream(pathSDCard);
        byte[] buff = new byte[1024];
        int read = 0;
        try {
            while ((read = in.read(buff)) > 0) {
                out.write(buff, 0, read);
            }
        } finally {
            in.close();
            out.close();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return  pathSDCard;
}


private void shareFile(){
    try {
        String mediaPath = copyFiletoExternalStorage(R.raw.numer_1, "numer_1.mp3");

        Intent shareMedia = new Intent(Intent.ACTION_SEND);
        shareMedia.setPackage("com.facebook.orca");
        shareMedia.setType("audio/mp3");
        shareMedia.putExtra(Intent.EXTRA_STREAM, Uri.parse(mediaPath));
        startActivity(Intent.createChooser(shareMedia, "Compartiendo archivo."));
    } catch (Exception e) {
        Toast.makeText(getApplicationContext(), "Messenger nie jest zainstalowany", Toast.LENGTH_LONG).show();
    }
}

AccountsController.cs：

public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        services.AddSpaStaticFiles(configuration =>
        {
            configuration.RootPath = "ClientApp/dist";
        });

        services.AddDbContext<ApplicationDbContext>(options =>
        options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
        b => b.MigrationsAssembly("MyOrg")));
    }

我不确定是什么问题。您有任何解决办法的想法吗？
