Example one
Referring to fig. 1, the method for monitoring an instant chat application in this embodiment mainly includes:
a picture capturing step S101: and when the client monitors that the front end of the desktop shows the instant messaging tool needing to be monitored, the client captures the screen of the current desktop. Specifically, the image capturing step specifically includes:
1) monitoring applications displayed at the front end of the desktop.
For example, taking the client as a PC, and the PC is installed with a Windows system, this step may use the function getforegroundwindow to obtain the application of the desktop front end.
2) Judging whether the application is an instant messaging tool needing to be monitored, if so, performing screen capture at intervals of preset time T1, if the image file obtained by screen capture is different from the last image file, saving the image file obtained by screen capture into a local preset file directory, and carrying instant messaging tool information displayed at the front end of the currently monitored desktop and the acquired client address information in the name of the image file during saving.
Specifically, the instant messenger to be monitored can be preset, so that after the application at the front end of the desktop is determined in the last step 1), the application can be contrasted to find whether the application is the preset instant messenger to be monitored.
Specifically, the coordinates of the window can be obtained by using the function GetWindowRect to accurately capture the screen during screen capture.
For example, if the sizes of the two picture files are the same, the two picture files are considered to be the same, otherwise, the two picture files are considered to be different.
Wherein the preset time T1 may be 3 seconds, and the client address information may be an IP address of the client. The file name is: png, MMM represents the application name of the instant messaging tool, and XXX represents the screenshot sequence from the front end display of the MMM. For example, assuming that the user opened a WeChat with an IP of 127.5.6.9, the picture file name saved for the first time is 127.5.6.9_ weixin _1.png, 127.5.6.9_ weixin _2.png for the second time, and so on.
An uploading step S102: uploading the picture file obtained by screen capture, the instant messaging tool information displayed at the front end of the desktop and the client address information to a server;
specifically, the uploading step S302 specifically includes: scanning the preset file directory once every preset time T2, and if the scanning finds that a new picture file exists in the preset file directory, uploading the newly found picture file to the server side in an FTP transmission mode. For example, an ftp file transfer can be performed using libcurl library functions. The preset time T2 may be 3 seconds. In addition, after each uploading is finished, the uploaded files are removed from the preset file directory.
Receiving step S103: the server receives and stores the picture file uploaded by the client;
specifically, if the client uploads the picture file in an FTP manner, the server correspondingly receives the picture file in the FTP manner. In this embodiment, the server receives the picture file transmitted in the FTP transmission manner, and stores the picture file in the preset picture file receiving directory. The name of the picture file carries the information of the instant messaging tool and the address information of the client, which can refer to a part of the above embodiments and is not described herein again. In this embodiment, the server side adopts a linux server of centros 7, picture reception is realized by an ftp service program vsftpd in the system, and an ftp service is opened by default to receive a file.
An identification step S104: and the server identifies the received picture file by the picture, and stores the identified chat content, the instant messaging tool information carried by the picture file and the client address information in an associated manner.
The step S104 specifically includes: scanning a preset picture file receiving directory once every preset time T3, if a new picture file exists in the preset picture file receiving directory, extracting instant communication tool information and client address information from the name of the newly found picture file, calling the newly found picture file for picture identification, writing the identified chat content into a text file of an appointed directory, wherein the name of the written text file carries the extracted instant communication tool information and client address information.
The preset time T3 may be 10 seconds. And after each identification, removing the identified file from the preset picture file receiving directory. In the embodiment, the existing tesseract-ocr identification program is adopted to identify the picture. In this embodiment, the text file is a selected TXT file, and of course, theoretically, other files, such as word, may also be selected. The name of the text file is the same as the corresponding picture file, for example, the picture file is IP _ MMM _ xxx.png, and the identified text file is IP _ MMM _ xxx.txt.
Query processing step S105: and when the server side obtains the query instruction, all the stored instant messaging tool information associated with the client address information carried by the query instruction and the chat content associated with each instant messaging tool information are used as query results.
Preferably, the query can be realized by combining Apache, PHP and a relational database (such as Mysql). Therefore, the step further comprises: the server scans the appointed directory once every preset time T4, if a new text file exists in the appointed directory, the instant communication tool information and the client address information are extracted from the name of the newly found text file, the newly found text file is opened to read the chat content, and the extracted instant communication tool information and the client address information as well as the read chat content are stored in a relational database in an associated manner for being inquired by a WEB server Apache. Wherein the preset time T4 may be 5 seconds. In addition, in this embodiment, after the information carried by the text file is stored in the relational database each time, the text file is removed from the designated directory. In addition, when the information is stored in the relational database, the address information of the client is used as a main key for storage, so that subsequent query is facilitated.
For example, an Apache server is developed at a server, a front-end query page is realized by using a PHP, an administrator can open the PHP front-end query page through any terminal, then IP information is input, a query instruction carrying the IP information is sent to the Apache server by the front-end query page, the Apache server extracts the IP information from the query instruction after receiving the query instruction, then a query result can be obtained by querying Mysql according to the IP information, and the query result is returned to the PHP front-end query page for display.
