获取spring cloud gateway POST请求体的时候,会有很多坑,网上大多数解决方案是 /** 这种方法在spring-boot-starter-parent 2.0.6.RELEASE + Spring Cloud Finchley.SR2 body 中生效, 但是在spring-boot-starter-parent 2.1.0.RELEASE + Spring Cloud Greenwich.M3 body 中不生效,总是为空 */ private String resolveBodyFromRequest(ServerHttpRequest serverHttpRequest) { Flux<DataBuffer> body = serverHttpRequest.getBody(); AtomicReference<String> bodyRef = new AtomicReference<>(); body.subscribe(buffer -> { CharBuffer charBuffer = StandardCharsets.UTF_8.decode(buffer.asByteBuffer()); DataBufferUtils.release(buffer); bodyRef.set(charBuffer.toString()); });

SpringCloud之网关服务(gateway)

前言 网关服务在SpringCloud中有很重要的作用。 可以将服务跟外网进行隔离起到一定的保护作用,同时服务间局域网通信更加快捷。而且在网关中可以做限流、权限校验,使得服务更加专注自身业务。比如说下订单需要登录权限,限流,我们在本篇将介绍如何使用。 搭建网关项目 注意:需要添加Eureka Discovery,Zuul路由组件。 1.入口添加@EnableZuulProxy注解 2.配置文件 server: port: 9000 #指定注册中心地址 eureka: client: serviceUrl: defaultZone: http://localhost:8761/eureka/ #服务的名称 spring: application: name: api-gateway #自定义路由映射 zuul: routes: order-service: /apigateway/order/** product-service: /apigateway/product/** #统一入口为上面的配置,其他入口忽略 ignored-patterns: /*-service/** #处理http请求头为空的问题 sensitive-headers: 我们启动EurekaServer、productService、OrderService、apigateway,通过访问:

路由过滤器允许以某种方式修改传入的HTTP请求或传出的HTTP响应,路径过滤器的范围限定为特定路径,Spring Cloud Gateway包含许多内置的GatewayFilter工厂。 Spring Cloud Gateway限流就是通过内置的RequestRateLimiterGateWayFilterFactory工厂来实现的。 当然,官方的肯定不能满足我们部分业务需求,因此可以自定义限流过滤器。 ## yml如下配置,就可以为该路由添加此拦截器: spring: cloud: gateway: routes: - id: test_route uri: localhost predicates: - Path=/host/address filters: - name: RequestRateLimiter args: ## 允许用户每秒执行多少请求,而不会丢弃任何请求。这是令牌桶填充的速率。 redis-rate-limiter.replenishRate: 1 ## 是一秒钟内允许用户执行的最大请求数。这是令牌桶可以容纳的令牌数。将此值设置为零将阻止所有请求。 redis-rate-limiter.burstCapacity: 3 ## KeyResolver是一个简单的获取用户请求参数 我这里以主机地址为key来作限流 key-resolver: "#{

概念 看 这篇 。 特别是Highlight部分: 访问服务如ADW,对象存储等无需走外网。 region级别的服务,因此只限于region内的服务。 替换了之前所需的internet gateway或NAT gateway。不过下载补丁还是需要NAT gateway。 感觉大部分是通过API/SDK集成,在OCI console中暂未见集成。 支持列表 看 这篇 。 实战 推荐 Connect Private Instances with Oracle Services Through an Oracle Cloud Infrastructure Service Gateway 和Access Oracle Services Privately with a Service Gateway](https://blogs.oracle.com/cloud-infrastructure/access-oracle-services-privately-with-a-service-gateway),都是同一人写的。 都试过,没问题。 OCI CLI 看 这里 。 命令行选项包括: Commands: attach Adds the specified [Service] to the list of... change-compartment Moves a service

This flex/amfphp application works fine on my computer, even though it accesses an Oracle database on another server. However, when I try to access it from another computer, this is the error I get. I'll try and put the most relevant code in. (My browser tell me this is an ActionScript error). Fault faultString="Send failed" faultCode="Client.Error

Is it possible to get the default gateway IP and MAC addresses in java?

我的未来我决定 提交于 2019-12-12 17:10:55
问题 I'm trying to find a way to access the IP and MAC addresses for the default gateway from a java applet to be run on a website, is this possible? 回答1: You can't do that kind of thing in Java, like getting the SSID on a Wifi network. This low-level hardware information can not be obtained in Java in a cross-platform way and Java only allow you to work in the Transport (TCP) level, aka use sockets. If you need this kind of information, try invoking a OS command tool using Runtime.getRuntime()

问题 I would like to be able to allow users to select a certain option on checkout, and then they will be redirected to the bank page where they use their credit info to pay, then redirected back to magento and set order as approved on success or fail if not I have been messing around with magento's code for a couple of days, I was able to 'hack' through the onepage controller to do the redirect and then come back, but I am not able to change the status of the order to 'approved' from that
