我在Zuul有一个场景,URL路由的服务也可能已关闭.因此,响应主体在JSON主体响应中被抛出500 HTTP Status和ZuulException.

{
  "timestamp": 1459973637928,
  "status": 500,
  "error": "Internal Server Error",
  "exception": "com.netflix.zuul.exception.ZuulException",
  "message": "Forwarding error"
}

我想要做的就是自定义或删除JSON响应,并可能更改HTTP状态代码.

我试图用@ControllerAdvice创建一个异常处理程序,但处理程序没有抓住异常.

更新:

所以我扩展了Zuul过滤器,我可以看到它在执行错误后进入run方法,然后如何更改响应.以下是我到目前为止所得到的.我在某处读到了有关SendErrorFilter的内容,但我如何实现它以及它做了什么？

public class CustomFilter extends ZuulFilter {

    @Override
    public String filterType() {
        return "post";
    }

    @Override
    public int filterOrder() {

        return 1;
    }

    @Override
    public boolean shouldFilter() {
        return true;
    }

    @Override
    public Object run() {
        final RequestContext ctx = RequestContext.getCurrentContext();
        final HttpServletResponse response = ctx.getResponse();
        if (HttpStatus.INTERNAL_SERVER_ERROR.value() == ctx.getResponse().getStatus()) {
            try {
                response.sendError(404, "Error Error"); //trying to change …

所以我将Hystrix-AMQP的依赖项添加到我的服务中,日志文件变得疯狂,它只是继续记录指标的东西.我需要那个罐子才能将它与涡轮AMQP一起使用.

这是我在hystrix的gradle中所拥有的: -

compile         ("org.springframework.cloud:spring-cloud-starter-hystrix:1.0.6.RELEASE")
compile         ('org.springframework.cloud:spring-cloud-starter-bus-amqp:1.0.6.RELEASE')
compile         ('org.springframework.cloud:spring-cloud-netflix-hystrix-amqp:1.0.7.RELEASE')
compile         ('com.netflix.hystrix:hystrix-javanica:1.5.2')

这是继续在我的日志中生成它继续运行: -

我正在调用bitbucket API来获取repo中的所有文件.我已达到这样的程度,我可以获取repo中所有文件夹的列表,并对repo中的所有根文件夹进行第一次API调用,并获取所有文件夹的前1000个文件列表.

但问题是bitbucket api一次只能给我每个文件夹1000个文件.

我需要附加一个查询参数&start = nextPageStart并再次进行调用,直到它为null并且每个API的isLastPage为true.如何使用以下代码实现这一目标？

我从第一次调用api获得nextPageStart.请参阅下面的API响应.

下面是我到目前为止的代码.

任何帮助或指导表示赞赏.

来自每个文件夹调用的各个API的响应.

{
    "values": [
        "/src/js/abc.js",
        "/src/js/efg.js",
        "/src/js/ffg.js",
        ...
    ],
    "size": 1000,
    "isLastPage": false,
    "start": 0,
    "limit": 1000,
    "nextPageStart": 1000
}

函数,我进行异步调用以获取文件列表

export function getFilesList() {
  const foldersURL: any[] = [];
  getFoldersFromRepo().then((response) => {
    const values = response.values;
    values.forEach((value: any) => {
    //creating API URL for each folder in the repo
      const URL = 'https://bitbucket.abc.com/stash/rest/api/latest/projects/'
                   + value.project.key + '/repos/' + value.slug + '/files?limit=1000';
      foldersURL.push(URL);
        });
    return foldersURL;
      }).then((res) => {

我在反应应用程序中使用auth0进行LinkedIn身份验证.我在设置localhost:3000/upload中设置了回调网址,在用户登录后localhost:3000/login跳转,他们将重定向到localhost:3000/upload.但是,我总是收到此错误:url localhost:3000/login不在回调网址列表中.为什么auth0会在登录后返回到您刚刚登录的页面.不应该是一些不同的URL.它对我来说没有意义.

编辑:

export default class AuthService {
  constructor(clientId, domain) {
    // Configure Auth0
    const options = {
      allowedConnections: ['linkedin'],
      auth: {
        params: {responseType: 'code'}
      }
    };  
    this.lock = new Auth0Lock(clientId, domain, options)
    // Add callback for lock `authenticated` event
    this.lock.on('authenticated', this._doAuthentication.bind(this))
    // binds login functions to keep this context
    this.login = this.login.bind(this)
    this.loggedIn = this.loggedIn.bind(this)
  }

  _doAuthentication(authResult){
    // Saves the user token
    console.log(authResult);
    this.setToken(authResult.idToken)
    this.lock.getProfile(authResult.idToken, (error, profile) => {

我正在部署一个使用 next.js 到 openshift 的节点项目，我在其中设置了环境变量 MY_ENV。我已将publicRuntimeConfig配置添加到 next.config.js 以访问它的客户端。它在我的本地工作，但是当它的容器化和部署publicRuntimeConfig是undefined.

这是我从 next.config.js 的配置

module.exports = {
  publicRuntimeConfig: { // Will be available on both server and client
      isProd: process.env.MY_ENV ? process.env.MY_ENV.includes('prod'): false,
      isStaging: process.env.MY_ENV ? process.env.MY_ENV.includes('staging') : false

我正在尝试实施Turbine AMQP来整合从多个服务到Hystrix Dashboard的所有流.

所以我在gradle文件中添加了几个依赖项,之后由于某种原因我无法启动我的应用程序.

来自启动的LOGS,我看到异常.

[LogMessage=Application startup failed]

简单我有一个看起来像这样的对象,它直接从我的chrome浏览器中的存储过程返回.我怎样才能删除那些说null出来的javascript/angular 2？

宾语

我正在使用微服务架构构建Rest api.我有多个api用户,我们已经进入多个项目.除了我无法将面向用户的用户映射到zuul中的应用程序URL之外,我还准备好了其他所有内容.

面向网址的用户是:user/v1/accountholders/{id}/cards,我的应用程序的实际网址是/ user-cards/v1/accountholders/{id}/cards.

这里的id是路径变量.下面是其他类似的api url,所以如果有一种方法在zuul中一般配置它们.此外,应用程序URL的上下文根也是Eureka中的项目名称.

Other similar urls are:

client side:- /user/v1/accountholders/{id}/cards/{cardid}
application:- /user-cards/v1/accountholders/{id}/cards/{cardid}

client side:- /user/v1/accountholders
application:- /user-cardholder/v1/accountholder

client side:- /user/v1/accountholders
application:- /user-cardholder/v1/accountholder

client side:- /user/v1/accountholders/{id}
application:- /user-cardholder/v1/accountholders/{id}

client side:- /user/v1/accountholders/{id}/accounts
application:- /user-accounts/v1/accountholders/{id}/accounts

client side:- /user/v1/accountholders/{id}/accounts/{accid}
application:- /user-accounts/v1/accountholders/{id}/accounts/{accid}

需要一些帮助来在zuul的属性或yml文件中进行设置.我还没有能够在映射中取得任何进展.任何输入都会有所帮助.

解决: - 从@Daniel获得输入后(这是接受的答案)这是我在zuul配置中使用的: -

zuul:
 routes:
   User-Cards: 
        path: /user/v1/accountholders/*/cards/**
        url: http://desktop-uvkv1ed:9999/user-cards/v1/accountholders
   User-Transactions1: 
        path: /user/v1/accountholders/*/transactions
        url: http://desktop-uvkv1ed:5555/user-transactions/v1/accountholders
        service-id: User-Transactions
   User-Transactions2:  
        path: /user/v1/accountholders/*/accounts/*/transactions

我的微服务需要使用双向 ssl。每个微服务都是一个 Spring Boot 应用程序，注释为：

@SpringBootApplication
@EnableFeignClients
@EnableDiscoveryClient
@EnableZuulProxy
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

每个 yml 对 eureka/ribbon 都有类似的配置：

eureka:
    client:
        service-url:
          defaultZone: ${EUREKA_CLIENT_SERVICEURL_PROTOCOL:http}://${EUREKA_CLIENT_SERVICEURL_HOST:192.168.99.100}:${EUREKA_CLIENT_SERVICEURL_PORT:8761}/eureka/
    instance:
        secure-virtual-host-name: ${spring.application.name}
        prefer-ip-address: true
        non-secure-port-enabled: ${EUREKA_NON_SECURE_PORT_ENABLED:false}
        secure-port-enabled: ${EUREKA_SECURE_PORT_ENABLED:true}
        secure-port: ${server.port}
ribbon:
    IsSecure: true
    eureka:
        enabled: true

每个微服务都有一个控制器，该控制器公开用于各种功能的 REST API。

当一个微服务需要调用另一个微服务端点时，我尝试通过创建该微服务的客户端接口来实现：

@FeignClient(name = "user", configuration = FeignConfiguration.class, url = "https://user")
public interface UserClient {
    @RequestMapping(method = RequestMethod.GET, value = "/test")
    String testUser();
}

这是 Feign 配置：

我已经用MongoDB Image设置了一个docker。默认情况下，没有设置密码。我创建了一个用户并为其分配了角色，效果很好。但是问题在于，无需身份验证仍然可以建立连接。

1. 使用身份验证>正确的用户名，正确的密码->已连接进行连接

2. 使用身份验证连接>用户名正确，密码错误->连接失败

3. 未经身份验证的连接>已连接

我要第三点停止工作。
