当我在 asp.net webapi 2 中设置 OAuth 授权服务器时，如何将令牌端点设置为接受 json 而不是表单编码的帖子？

使用示例http://www.asp.net/web-api/overview/security/individual-accounts-in-web-api

我试图发送应用程序/json

{
"grant_type":"password",
"username":"Alice",
"password":"password123"
}

我收到响应 400 Bad Request

{
  "error" : "unsupported_grant_type"
}

其中作为 application/x-www-form-urlencoded 的内容类型和grant_type=password&username=Alice&password=password123 预期的作品主体。

200 好

根据您当前的实施情况，OAuthAuthorizationServerHandler您不能。

private async Task InvokeTokenEndpointAsync()
{
     DateTimeOffset currentUtc = Options.SystemClock.UtcNow;
     // remove milliseconds in case they don't round-trip
     currentUtc = currentUtc.Subtract(TimeSpan.FromMilliseconds(currentUtc.Millisecond));

     IFormCollection form = await Request.ReadFormAsync();
     var clientContext = new OAuthValidateClientAuthenticationContext(
                Context,
                Options,
                form);

     await Options.Provider.ValidateClientAuthentication(clientContext);

     if (!clientContext.IsValidated)
     {
          _logger.WriteError("clientID is not valid.");
          if (!clientContext.HasError)
          {
               clientContext.SetError(Constants.Errors.InvalidClient);
          }
          await SendErrorAsJsonAsync(clientContext);
          return;
      }

      var tokenEndpointRequest = new TokenEndpointRequest(form);
}

所以为了尝试这个，你需要提供你自己的OAuthAuthorizationServerMiddleware重载实现，CreateHandler这样你就可以提供你自己的实现AuthenticationHandler<OAuthAuthorizationServerOptions>
