问题 I've been trying to get XSRF working on a webapp to no avail. I am looking at a typical login implementation. I am following Google's code. I changed my web.xml to include: <servlet> <servlet-name>xsrf</servlet-name> <servlet-class>com.google.gwt.user.server.rpc.XsrfTokenServiceServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>xsrf</servlet-name> <url-pattern>/gwt/xsrf</url-pattern> </servlet-mapping> <context-param> <param-name>gwt.xsrf.session_cookie_name</param-name>

how to centralize “loading” screen for GWT RPC?

阅读更多关于 how to centralize “loading” screen for GWT RPC?

问题 How can I centralize management of a "loading" icon for GWT async RPC calls? I'm looking for a way to have every async call automatically kick off a timer. When the timer fires, if the RPC has not yet completed, a "loading" icon should be displayed. When the RPC completes (either onSuccess() or onFailure() ) the loading icon should be removed. It's tedious to do this manually for each call, and in fact quite easy to get it wrong and leave the user with a stuck UI. Could generators be used for

Does RPC have a timeout mechanism?

阅读更多关于 Does RPC have a timeout mechanism?

问题 If RPC does not have a timeout mechanism, how do I "kill" an RPC call if it is trying to call an RPC method of a server that is closed? 回答1: You can use channels to implement a timeout pattern: import "time" c := make(chan error, 1) go func() { c <- client.Call("Service", args, &result) } () select { case err := <-c: // use err and result case <-time.After(timeoutNanoseconds): // call timed out } The select will block until either client.Call returns or timeoutNanoseconds elapsed. 回答2: if you

Make Tornado able to handle new requests while waiting response from RPC over RabbitMQ

阅读更多关于 Make Tornado able to handle new requests while waiting response from RPC over RabbitMQ

问题 I have web-server listening clients and when someone hit handler server send an RPC message to RabbitMQ and waiting for response while keeping connection. When response from RMQ came server pass it to the client as response to request. All async examples in Tornado docs works with their own http.fetch_async() or something like that methods, and I understand that I have to wait/read for RMQ asynchronously... But how? And even worse - sometimes I have to send several messages at one moment (I

RPC to have values changed in-place in C

阅读更多关于 RPC to have values changed in-place in C

问题 background I am writing a basic RPC client/server code for a class and one of the requirements is that the server side must change the values in-place. The final goal is to pass a vector from the client to the server. But since I am just learning RPC, I decided to start from basic examples. Below I have a simple code in which I compute the square of a number. For this example I'd like to change the result in-place already. issue As you can see in my server.c , I tried to change the value in

如何从0到1设计一个类Dubbo的RPC框架

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> RPC和RPC框架 1.RPC(Remote Procedure Call) 即远程过程调用, 主要解决远程通信间的问题，不需要了解底层网络的通信机制。 2.RPC框架 RPC框架负责屏蔽底层的传输方式（TCP或者UDP）、序列化方式、以及通信细节。实际使用中，并不需要关心底层通信细节和调用过程，让业务端专注于业务代码的实现。国内大家熟知的PRC框架，阿里的HSF和Dubbo(开源) Dubbo的发展由来 1. 业务规模小比如早期一个应用Java War包，将所有功能都打包，部署在一个单机服务器，调用接口也比较方便，不涉及到任何分布式场景。 2.业务规模变大随着业务的快速发展，业务越来越多、子系统也越来越多时。比如：淘宝的交易系统、商品系统、用户系统、评价系统…上百个系统的出现。系统变得越来越复杂，业务代码依然耦合在一起。比如最早期的淘宝denali工程，包含所有业务系统的代码，就仅打包部署都需要很长的时间。并且，随着每个业务线的快速发展，业务代码耦合在一起，上线后出现问题急需要回滚代码，拉分支、大量的代码merge工作，这个过程极其痛苦。这个时候，你会发现技术已经成了业务的瓶颈，急需把业务单独抽离出来，各自单独部署。 3.Dubbo和HSF的出现应用系统一旦涉及到拆分部署，问题就来了
