javascript - NodeJS - EMFILE Exception - request piped to writeStream -

-

Getting timely images from another server in a server Nodjes-time and store them in a specific folder.

I am doing this with this command (a function that gets by the timer every 10 seconds): 

  request (cameraRequestOptions) .pipe (fs .createWriteStream (". / Campics / cam" + Camera ID + "Picture" + latest camera featurenumber + ".jpg"));   
 Changing the name of the target image file due to "the latest camera fixtures".  
 I'm having trouble with an amiffeil exception, the strange thing is that this is happening only on some issues the server is running and it seems that it only happens after a long time.  
 As I have already found, it means doing something wrong so many Failstrym or socket opening IM that it could be that I'm not sure that my pipe: I written Strit or Close the request? And when how?  
 Documentation says:  
 
 Readable Pip (destination, [options]) #  
 Destination data to write destination writeable stream  
 Option Object Pipe Option  
 End Boolean Author Ends When Reader Ends  
   
 
 
 " Post-text "itemprop =" text "> 
 The problem seems to be more complicated, I add to the callback function to determine if all the streams and requests are closed properly Programming are, so it seems that the problem is caused by some other pipes I. The following stream using Oration:  
  var fsCTmp = fs.createWriteStream ( ". / Campics /" + newLogId + "camera" + Kamraaidi + "picture" + picNum + ".jpg" ); FsCTmp.on ('end', wscfTest); Fs.createReadstream ("./Campix / Camera" + Camera ID + "Photo" + picNum + ".jpg"). Pipe (fsCTmp) .on ('finish', rsfTest);   
 
  var fsCP = fs.createWriteStream ( ". ./ camp / camera" + Kamraaidi + "photo" latest Kamraficr number + ".jpg"); FSCP.On ('Finnish', WSFTest); Request (Camerrequest Option) .pip (FSCP) .on ('Finnish', Rftext);   
 
  var fsWTmp = fs.createWriteStream ( ". ./ camp / + Skriyalarmficshatojhadtoog [J] .logId +" Cam "+ Kamraaidi +" picture "+ Skriyalarmficshaonaoadtiolog [j]. PicNum + ".jpg"); FsWTmp.on ( 'end', wscfTest); Fs.createReadStream (picturePath) .pipe (fsWTmp) .on ( 'end', Arsftest);   
 
 and im sending a webclient via  
  res.sendfile (& lt; path & gt;);   
 I'm logging in to every callback functions in the console, everything works fine, but by now I'm doing this Only then could test itself on the PC, and the exception has been made only after a few pipes (about 10-100), except for each maskin.

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...
