我们一直在编写一些代码来测试我们的端点和身份验证过程。我们使用 Cognito 进行身份验证，我们的端点需要具有隐式授权流程的访问令牌。

阅读 Amazon 的文档后，我们成功地使用以下代码获取了 openid 令牌：

    AmazonCognitoIdentity identityClient = new AmazonCognitoIdentityClient(
            new BasicAWSCredentials("XXXXXXXXXXXXXXXXXXXXX",
                    "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
    );
    identityClient.setRegion(Region.getRegion(Regions.EU_WEST_1));
    GetOpenIdTokenForDeveloperIdentityRequest request =
            new GetOpenIdTokenForDeveloperIdentityRequest();
    request.setIdentityPoolId("eu-west-1:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
    Map<String,String> logins = new HashMap<>();
    logins.put("acceptance-tests", "acceptance-tests");
    request.setLogins(logins);

    GetOpenIdTokenForDeveloperIdentityResult response =
            identityClient.getOpenIdTokenForDeveloperIdentity(request);
    String identityId = response.getIdentityId();

    String token = response.getToken();

我们只是不知道如何将 openid 令牌交换为访问令牌来调用我们的端点。

也就是说，我们甚至不确定是否真的需要先获取 openid 令牌才能获取访问令牌。

在我们尝试使用下面的代码来获取访问令牌之前，但是我们的端点不接受我们获得的令牌。我们获得的令牌与我们通过 cognito UI 登录时获得的令牌不同。

final String clientId = "XXXXXXXXXXXXXXXXXXXXXXXXX";
final String region = "eu-west-1";
final String username = "USERNAME";
final String password = "PASSWORD";
AWSCognitoIdentityProvider cognitoClient = AWSCognitoIdentityProviderClientBuilder.standard()
            .withRegion(region)
            .build(); …

我已经使用paperjs了一年,没有任何问题.在Chrome更新后(Version 55.0.2883.87 m),我在2个月内未触及的一些生产代码开始失败error: item.setRampPoint is not a function:

paper-full.js:13213 Uncaught TypeError: item.setRampPoint is not a function

at offset (paper-full.js:13213)

at drawAddLaneButtons (tlc.js:267)
at Path.window.drawTlcElements (tlc.js:62)

如果我setRamPoint在paperjs代码中注释掉它,它会再次开始工作.

当我尝试将SVG加载到页面时会发生这种情况,但是,正如我之前所说,它在很长一段时间内都运行正常.

我使用的是版本0.9.25 paperjs.

有任何想法吗？

我正在使用 nestjs 并且我试图创建一个自定义装饰器：

import { createParamDecorator, ExecutionContext } from '@nestjs/common';
import { User } from './user.entity';

export const GetUser = createParamDecorator(
  (data, ctx: ExecutionContext): User => {
    const req = ctx.switchToHttp().getRequest();
    return req.user;
  },
);

装饰器在这里使用：

  @Post('/test')
  @UseGuards(AuthGuard())
  test(@GetUser() user: User) {
    console.log(user);
  }

但我收到以下错误：

[Nest] 15053   - 26/03/2020, 13:28:19   [ExceptionsHandler] ctx.switchToHttp is not a function +61625ms
