如何配置ASP.NET Core在驼峰情况下返回异常？

如何解决如何配置ASP.NET Core在驼峰情况下返回异常？

当我的应用程序引发未处理的异常时，我返回状态码500（内部服务器错误），如本例所示：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class CognitoController extends Controller
{

    private $key;
    private $secret;
    private $region;
    private $version;
    private $client_id;
    private $client_secret;
    private $user_pool_id;

    private $aws;
    private $client;

    public function __construct()
    {

        $this->key = 'xxxxxx';
        $this->secret = 'xxxxxx';
        $this->region = 'xxxxxx';
        $this->version = 'latest';
        $this->client_id = 'xxxxxx';
        $this->client_secret = 'xxxxxx';
        $this->user_pool_id = 'xxxxxx';

        $config = [
            'credentials' => [
                'key' => $this->key,'secret' => $this->secret,],'region' => $this->region,'version' => $this->version,'app_client_id' => $this->client_id,'app_client_secret' => $this->client_secret,'user_pool_id' => $this->user_pool_id,];

        $this->aws = new \Aws\Sdk($config);

        $this->client = $this->aws->createCognitoIdentityProvider();

    }

    public function login()
    {
        $username = 'guest';
        $password = 'password';

        $result = $this->client->adminInitiateAuth([
                                    'AuthFlow' => 'ADMIN_NO_SRP_AUTH','AuthParameters' => [
                                        'USERNAME' => $username,'PASSWORD' => $password,'SECRET_HASH' => $this->secretHash($username),'ClientId' => $this->client_id,'UserPoolId' => $this->user_pool_id,]);

        $access_token = $result->get('AuthenticationResult')['AccessToken'];

        echo '<pre>';
        print_r( $result );
        echo '<br/>';
        print_r( $access_token );
        echo '</pre>';
    }

    public function register()
    {
        $username = 'guest';
        $password = 'password';
        $email = '[e-mail]';
        $phone_number = '[phone]';

        $result = $this->client->signUp([
                                    'ClientId' => $this->client_id,'Password' => $password,'SecretHash' => $this->secretHash($username),'UserAttributes' => [
                                        [
                                            'Name' => 'phone_number','Value' => $phone_number,[
                                            'Name' => 'email','Value' => $email,]
                                    ],'Username' => $username
                                ]);

        echo '<pre>';
        print_r( $result );
        echo '</pre>';

    }

    public function register_confirm()
    {
        $username = 'guest';
        $confirmationCode = '123456'; // from email verification code

        $result = $this->client->confirmSignUp([
                                    'ClientId' => $this->client_id,'Username' =>  $username,'ConfirmationCode' => $confirmationCode,]);

        echo '<pre>';
        print_r( $result );
        echo '</pre>';
    }

    public function list()
    {
        $search = ['UserPoolId' => $this->user_pool_id];

        $users = $this->client->listUsers($search)->toArray();

        echo '<pre>';
        print_r( $users );
        echo '</pre>';
    }

    private function secretHash($username) {
        $clientId = $this->client_id;
        $clientSecret = $this->client_secret;
        $s = hash_hmac('sha256',$username . $clientId,$clientSecret,true);
        return base64_encode($s);
    }

}

JSON返回为：

[HttpGet]
public ActionResult<string> Get()
{
    try
    {
        throw new Exception("Exception return test.");
    }
    catch (Exception ex)
    {
        return StatusCode(StatusCodes.Status500InternalServerError,ex);
    }
}

但是我希望所有属性都以驼峰格式设置。

在ASP.NET Web API中，您可以实现{ "ClassName": "System.Exception","Message": "Exception return test.","Data": null,"InnerException": null,"HelpURL": null,"StackTraceString": null,"RemoteStackTraceString": null,"RemoteStackIndex": 0,"ExceptionMethod": null,"HResult": -2146233088,"Source": null,"WatsonBuckets": null } 接口并将其替换在IContentNegotiator中，例如explained here。使用此配置，API的每个输出都是驼峰式的，包括异常消息。

在ASP.NET Core 2.2中，即使默认情况下API返回的对象属性是驼峰式的，也不例外。

我尝试过（在Startup.cs中）：

HttpConfiguration

但是没有运气。我还检查了services.AddMvc() .AddJsonOptions(options => { options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); options.UseCamelCasing(true); }) ，并确认OutputFormatters已经拥有JsonOutputFormatter作为其ContractResolver。无论如何，我都尝试过，但除此之外，结果没有变化：

CamelCasePropertyNamesContractResolver
