Difference between Localhost and opening html file

由 不羁的心 提交于 2019-12-04 05:33:27
What is the fundamental difference running a file using a server in localhost, and opening a file such as file:///Users/$user_name/$your_directory/index.html , assuming no backend is used, and it is only frontend and contains html/css/js How does this also affect interactions with other server ie. ajax requests? I am sorry if this is too broad, but I haven't found a solid answer to these underlying questions. Fundamentally, assuming at some point you're going to host the result on an actual web server, the former matches the target environment while the latter doesn't. Browsers treat local

Easiest way to get list of files in the server directory

由 杀马特。学长 韩版系。学妹 提交于 2019-12-04 03:24:24
I need to get array of all images (or simply of all files) in directory (e.g. www.example.com/images/). I prefer to use JavaScript but it's hard to make. So should I use PHP, meybe? Could you please help me - I'm not good at this. Thank you very much! Javascript cannot fetch all files on a server, as it is a client-side langugage. http://php.net/manual/en/function.glob.php is what you need. $all = glob('/path/to/dir/*.*'); $images = glob('/path/to/dir/*.{jpg,png,gif}'); I disagree with @mariobgr. If there is no server setting preventing a directory listing, then the html generated by

Asynchronous C client for a multiclient C server

由 一曲冷凌霜 提交于 2019-12-04 01:59:49
问题 I have a client which is working fine, but whenever I run a new client, sometimes I don't receive the sent message on the other client already running, while using telnet it works flawlessly, the message "broadcasts" to all connected clients, and I want whenever a message is received to one of the clients to show even if I didn't already send a message. Should I use select on clients ? and what should be changed ? client.c: #include <stdio.h> //printf #include <string.h> //strlen #include

How to make the server backend of a mobile app?

由 佐手、 提交于 2019-12-04 01:57:31
I am an Android developer and I want to make an app which shows users on a map and performs tasks based on their location. The whole model of the app has to run in the server. I need an API which: Receives user location Performs calculations based on the location of the users Sends response to specific users with the results The problem is that I have 0 experience in doing server side programming. Can you please suggest me a way of making the server? I checked the Google Colud Platform and this video. The video addresses the connection between the app and the server, but what I really need is

Exception in thread “main” java.net.ConnectException: Connection refused: connect Socket Programming Java

由 ぐ巨炮叔叔 提交于 2019-12-04 01:50:59
问题 I recently learn about Socket Programming between client and server. So I thought of doing an exercise of connecting both client and server. However, I have encountered this error message when I try to run the code: Exception in thread "main" java.net.ConnectException: Connection refused: connect This is my client class code: public class clientpart { public static void main(String[]args) throws UnknownHostException, IOException { Scanner input = new Scanner(System.in); int port = 8080;

Does OpenSSL allow multiple SSL_CTX per process, one SSL_CTX used for server sessions and the other SSL_CTX for client sessions?

由 放肆的年华 提交于 2019-12-04 01:43:11
问题 I have a Linux process that needs to act as an SSL server (accept and service connections from other clients) but also needs to - in the same process - initiate client sessions with other SSL servers. I intend to create two separate SSL_CTX handles using two SSL_CTX_new() function calls, one invoked with server methods and the other with client methods. Is such dual-use of OpenSSL within a single process supported? My hope is that OpenSSL uses the SSL_CTX handle - and does not rely on global

Proximity alert for locations saved at server

由 只谈情不闲聊 提交于 2019-12-04 00:56:55
I did some search but could not find a suitable answer. My App should compare with multiple locations for proximity. This means I will not be able to save all the locations into my app to confirm the proximity using locationManager. I want the proximity confirmation to be done in the server What would be the best way to implement this? Would it be sensible if the app asks for proximity confirmation every time the devices moves around? I would try a different approach, since location updates from GPS are made once per second, and I don't think it's a good idea to ask the server each second for

Why is mysqlserver.lib file very large? Is this file neccessary in wamp stack?

由 守給你的承諾、 提交于 2019-12-04 00:00:57
Recently I created my development server using php7.0.1, mysql5.7 and apache 2.4.20. After I successfully got it running, I checked the file size of my server and found that it is almost 2 GB. So I digged further and found that mysqlserver.lib file inside mysql/lib folder is around 976 MB. So my problem is how can I make my server file size smaller? Is this mysqlserver.lib safe to delete? I don't see mysqlserver.lib in the wamp2.5 version of mysql. Any suggestion for making file size in mysql community edition smaller is welcome. The lib folder is there for you to compile MYSQL yourself if you
