java - FTPSClient raise an exception when trying to login() after logout() -

-

text>>

I want to write code in Java that connects to the server's list using FTP on the SSL protocol and receives some files from it is. Every server has a log in and a list of passwords. In every login I need to connect to the server in something like this: 

  // This is not a real code, this is just what I need to do For the sketch is (server server: server) {server.connect (); (Login password password: server.loginPasswordList) {server.login (login password); Server.getSomeFiles (); Server.logout (); } Server.disconnect (); }   
 I am using FTPSClient from Apache Commons:  
  ftpClient = ftpClient.connect ("host", port); Int reply = ftpClient.getReplyCode (); If (FTPReply.isPositiveCompletion (Answer)) {if (ftpClient.login ("Login", "Password")) {ftpClient.execPBSZ (0); FtpClient.execPROT ("P"); FtpClient.enterLocalPassiveMode (); Println (ftpClient.logout ()); // true} if (ftpClient.login ("another_login", "another_password")) {// Exception ftpClient.execPBSZ (0) is generated in this line; FtpClient.execPROT ("P"); FtpClient.enterLocalPassiveMode (); Println (ftpClient.logout ()); // true}}   
 This code fails when I try to logout and log in once in the same connection. I get this exception:  
  org.apache.commons.net.ftp.FTPConnectionClosedException: connection closed without signal   
 but if I close the connection (FtpClient.disconnect ();) after logout and then open it once again (ftpClient.connect ("host", port)) works fine in the code below.    ftpClient = ftpClient.connect ("host", port); Int reply = ftpClient.getReplyCode (); If (FTPReply.isPositiveCompletion (Answer)) {if (ftpClient.login ("Login", "Password")) {ftpClient.execPBSZ (0); FtpClient.execPROT ("P"); FtpClient.enterLocalPassiveMode (); Println (ftpClient.logout ()); // true}} ftpClien.disconnect (); FtpClient = ftpClient.connect ("host", port); Int reply = ftpClient.getReplyCode (); If (FTPReply.isPositiveCompletion (Answer)) {if (ftpClient.login ("another_login", "another_password")) {// It works fine ftpClient.execPBSZ (0); FtpClient.execPROT ("P"); FtpClient.enterLocalPassiveMode (); Println (ftpClient.logout ()); Of course I can use this code, but the problem is that there is a large list of servers and logins, and the creation of new connections takes 1 second, but ftpClient .login () only takes ~ 50 ms so if I use every login If I use code with new connection, it will take 3,150 ms on a server for three logins instead of 1150 ms. So what could be the reason why I can not log on to the server after logout?   
 
 
 This is not the legal client API for issuing any order after a shutdown, And then new login (); You should issue a reinitialize; Otherwise you can try just new login (without first logout), even if the second login is allowed on the same connection, although it is server-based and is not required.

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...
