问题 I want to know how can we obtain the cookies of the current page being accessed using a communication link between the content script and background page. This is for an extension. 回答1: You can use Content Scripts to access document.cookie for each website you visit. Then you can use Message Passing to pass the cookies from your Content Script to your Background Page. There are many examples on Stack Overflow for example: Chrome Extension: how to capture selected text and send to a web

问题 I'm trying to send a message to a topic which was created with both Enable duplicate detection and Enable partitioning options checked. I do not set SessionId and PartitionKey properties on my BrokeredMessage instance. According to this: If the queue or topic has the QueueDescription.RequiresDuplicateDetection property set to true and the BrokeredMessage.SessionId or BrokeredMessage.PartitionKey properties are not set, then the BrokeredMessage.MessageId property serves as the partition key.

问题 I am building a distributed system that consists of potentially millions of clients which all need to keep an open (preferrably HTTP) connection to wait for a command from the server (which is running somewhere else). The load of messages / commmands will not be very high, maybe one message / sec / 1000 clients which means it would be 1000 msg/sec @ 1 million clients. => it's basically about the concurrent connections. The requirements are simple too. One way messaging (server->client), only

问题 I'm trying to create a module for a flex application, and I want to send notifications to clients. I've been looking at the BlazeDS messaging service to push out the notifications to clients, but I want to be able to send certain updates to certain clients. The Flex notification framework doesn't seem to allow this - if we have a field in the message with a value of the user's user id for example, any client could theoretically subscribe to all messages for any given user id, and there's no

问题 I'm looking to build with Twilio's IP Messaging APIs using a cross mobile framework like React Native or Ionic. My question is - is this a sane request? I see that Twilio has a Javascript library that I plan to use. Examples of successes/failures would also help. My overall goal is to build in simple chat rooms cross platform. 回答1: If anyone else found their way here from a Google search, I recently released the code I developed to implement IP Messaging on React Native for my org. You can

问题 I'm looking to implement an in-app messenger in my current iPhone/android applications. The requirements are that it must be free, real-time, and provide push notifications. I've looked into creating the system myself, but have noticed quite a few apps implement very similar concepts so i figure there must be a drop in SDK/wrapper available. Here's an example of an app using the of the type of messenger to be implemented: Like a little: http://itunes.apple.com/us/app/lal-lite-likealittle-lite

问题 What is the basic difference between stream processing and traditional message processing? As people say that kafka is good choice for stream processing but essentially kafka is a messaging framework similar to ActivMQ, RabbitMQ etc. Why do we generally not say that ActiveMQ is good for stream processing as well. Is it the speed at which messages are consumed by the consumer determines if it is a stream? 回答1: In traditional message processing, you apply simple computations on the messages --

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I would like to pass a string to an Activity easily. Something like callback would be needed because when the string has to be passed then the Activity has to do something. public class MyHostApduService extends HostApduService { @Override public byte[] processCommandApdu(byte[]

问题 (or set multiple objects with one value) Is there a way to send multiple objects one message in one line. So like [someObject, otherObject reset]; like in LUA scripts (which I believe is C?) you can set mutliple objects: someThing, otherThing = 1 , 0 回答1: In short, no, neither Objective-C nor C support this feature. As an extreme measure, you can use -[NSArray makeObjectsPerformSelector:] and -[NSArray makeObjectsPerformSelector:withObject:] , such as [[NSArray arrayWithObjects:someObject,
