javascript - Flux architecture misunderstanding in example chat app -

-

I'm trying to understand. The authors mentioned this unidirectional data flow: Enter image details here

However In the example, there are dependencies between the action creators () and store () in the app, and store (,) and Web API Utils (), which is against unidirectional data flow rule: Enter image details here

Is it recommended to follow the given example? Has been done, or should it be designed in a better way?

Update

I found that ChatMessageUtils are not related to Web API utilities, so there should not be two arrows from the store pointing there, so they might be okay. However the relationship between action crews and the store is still weird.

The example is a little compelling, and how it was designed to try to show how to wait () The WebAPI aspect of the works is very semi-baked and should actually be modified.

However, MessageStore.getCreatedMessageData (text) A value passes in the store, it is still a gateer is not setting the data on the store. It is actually a utility system Is being used in the form, and a good revision (bridge request?) Will be to move that method to the Utilis module.

To make things better for the real world example, some things you do:

  • Instead of the operator, call the WebAPIutils in the store. It is fine as long as the response calls another ActionCreator, and it is not operated directly by setting up new data on the store. The important thing is that for new data of origin with one action, it is more important how the data emerges from the system, apart from how the system is entered.

  • Alternatively, you must have separate client-side versus server-side IDs for the message. There are some benefits of this, such as managing optimistic references. In that case, you want to generate a client-side ID in the Utilis module, and pass that ID to both the text sent along with the text and the WebAPI utility.

    Everyone said, yes, there is a need to amend the example.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
