detailed description

It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

The present application provides a method for establishing a connection. Referring to FIG. 1, FIG. 1 is a schematic flowchart of a first embodiment of a method for establishing a connection according to the present application.

The embodiment of the present application provides an embodiment of a connection establishment method. It should be noted that although the logical order is shown in the flowchart, in some cases, the illustrated or described may be performed in an order different from the ones herein. A step of.

The connection establishment method can be applied to the server, and the connection establishment method includes:

Step S10: After receiving the login request, the server verifies the login request, and obtains corresponding verification data, where the login request is sent by the client to the server after detecting the login request.

When the client detects a login request triggered by its user, it sends a login request to the server. After the server receives the login request sent by the client, the server verifies the login request, obtains the verification result, and obtains corresponding verification data according to the verification result. The login request is triggered by the client user when the client needs to connect to the server. The verification data includes, but is not limited to, a login string, a login device ID (identification number) number, a login user name, and a message ID number. The login string can determine whether the client that sends the login request has the right to establish a connection with the server; the login device ID number is the identity of the client, and the login device ID can determine which client the client established with the server is; The login user name is the identifier of the user who triggered the login request. The server can uniquely identify the user who triggered the login request by logging in the user name. The message ID is the data transmitted between the client and the server after the client and the server establish a connection. Logo. In this embodiment, the server can be XMPP (Extensible Messaging and Presence Protocol, a scalable communication and presentation protocol server.

Further, step S10 includes:

Step a, after the server receives the login request, extract the login user name and the login password in the login request.

Further, after the server receives the login request sent by the client, the login user name and the login password are extracted in the login request. The login password is the password required for the client user to log in to the client. Understandably, when the login user name and login password are correct, the user can successfully log in to the client.

Step b, performing login verification according to the login user name and the login password, to obtain corresponding verification data;

After the client detects the login request, the configuration information is read, the connection information connected to the server is set according to the configuration information, and the login request is sent to the server according to the connection information. .

After the server extracts the login user name and the login password in the login request, the server performs login verification according to the login user name and the login password, and obtains verification data corresponding to the login request. The server performs login verification based on the login user name and login password. The specific process is as follows: The server searches for the login user name in its database. If the server finds the login user name in its database, the server determines that the login user name is verified; if the server does not find the login user name in its database, the server determines that the login user name has not passed the verification. The server compares the login password with a pre-stored preset password in its database. If there is a preset password in the database that matches the login password, the server determines that the login password is verified; if the database does not have a preset password consistent with the login password, the server determines that the login password has not passed the verification.

When the login user name and the login password are verified, the server generates the verification data carrying the login string; when the login user name fails the verification, and/or the login password fails the verification, the server generates the verification data that does not carry the login string. .

Further, when the client detects the login request, the configuration information is read, the connection environment established with the server is determined according to the configuration information, and the connection information of the connection server is set according to the configuration information, and the HTTP (HyperText) is used according to the connection information. Transfer Protocol, Hypertext Transfer Protocol) sends a login request to the server.

Among them, the connection environment includes but is not limited to the test environment and the local environment. The local environment is the environment where the client and the server are connected, and the test environment is a preset environment. The configuration information includes the client type, the server's IP address, the server's port number, the communication technology type, the communication data transmission type, and the message parsing method. As in this embodiment, the communication technology type can be set to java non-blocking IO (java non-blocking IO); communication data transmission type can be set to protobuf, protobuf is a specified data propagation format; message parsing method can be used to transfer data to the server, according to google The protobuf protocol converts data into messages.

The connection information is the server's IP address and port number. The process of setting the connection information according to the configuration information by the client is: Step 1: Convert the read configuration information into Java. Map object. The configuration information is stored in the client (client).properties, stored in the form of key=value, and the properties represent a persistent set of attributes. Each key in the attribute list and its corresponding value are a string. Use Java when the client starts The File class reads the configuration information. To avoid excessive I/O (Input/Output) read/write operations affecting client performance, the client adds each row of key=value as a String object to a List<String> object list. In the middle, and the list is traversed, the String object of key=value is taken out in turn, and then the String is converted into an array. The array has only two elements [key, value], and a Map<String is used at this time. Key, String value> Converts the array object into a Java Map object.

Step 2: The client assigns a value to its system parameter class member variable to make Java The data in the Map object matches the corresponding member variable. System parameter class System The following member variables are defined in Config: 1client: client mode; 2transport: data transfer mode between client and server; 3host: server IP address; 4port: server port number; 5 Handlers: listens for processing classes. Each member variable has a set (set) and get (get) method. In this embodiment, the system is obtained by using reflection technology. All methods of the Config object, after traversing, filter out the beginning of the set, the method modification type is public or static, and the return type is void (empty type). The method name is substring(3) to get the new string, and Java. The key in the Map object is matched to get the corresponding value. If the value is null (null), then the next loop is entered; If the value is not null, the value is assigned to the member variable corresponding to system Config until Java. The data in the Map object is matched to the corresponding member variable, and the client parameter initialization is completed. Among them, public indicates that the data member and member function are open to all users, and all users can directly call it. Static means "global" or "static", used to modify member variables and member methods, can also form static static code blocks, but there is no concept of global variables in the Java language.

After the client sets the connection information of the connection server according to the configuration information, the client performs encapsulation and instantiation operations, and starts a listening thread to listen to the process of establishing a connection with the server through the listening thread, and obtain verification data returned by the server.

The process of the client performing the encapsulation and instantiation operations is: customizing a lazy loading class ExtensionLoader<T>, using a generic representation to cache any type of Java class; taking its corresponding ExtensionLoader<Client> object from the cache; The ExtensionLoader<Client> object is instantiated and gets an object client; look up the instance corresponding to the ExtensionLoader<Client> object in the cache. If the instance is looked up, the instance is returned; if the instance is not found, the configuration information is read. It should be noted that the configuration information is also stored in the format of key=value. The client is an interface class and has an implementation class AbStract. Client, AbStract Client has two implementation classes Swing Client and Console Client. The information in the configuration information is swing=Swing. Absolute path of the client class, console=Console The absolute path of the Client class is also obtained by using the reflection technique to get the corresponding class name according to the key, and then calling Class.forName to instantiate the instance of the Client and saving it to the cache. It should be noted that reflection technology is an important mechanism in .NET. The listener thread is a class that encapsulates and instantiates the client's process so that the listener thread can better listen to the entire process of creating a connection during the creation of the connection.

In step S20, the verification data is sent to the client, so that the client obtains the verification data, and after determining that the login operation corresponding to the login request is in a normal state according to the verification data, obtain the verification data. The login string in the verification data is converted, and the login string is converted into a request message and sent to the server.

After the server obtains the verification data, the verification data is sent to the client, so that the client receives the verification data, and determines that the login operation corresponding to the login request is in a normal state according to the verification data, and obtains the login string in the verification data. Convert the login string into a request message and send it to the server. Further, when the client receives the verification data, the verification data is saved into its system parameter class, so that the login string is obtained in the system parameter category during the process of establishing the connection with the server.

Further, step S20 includes:

Step c, sending the verification data to the client.

After the client receives the verification data, detecting whether a login string exists in the verification data;

If the login string is detected in the verification data, the login operation corresponding to the login request is determined to be in a normal state, the login string in the verification data is obtained, and the login string is converted into a request message. Sent to the server.

Further, when the server sends the verification data to the client, after the client receives the verification data, the client detects whether the login string exists in the verification data. If the login string is detected in the verification data, the client determines that the login operation corresponding to the login request is in a normal state, and obtains the login string in the verification data, converts the login string into a request packet, and sends the TCP through the nio technology. (Transmission The Control Protocol (Transmission Control Protocol) is connected to the server to send the request message to the server. Nio technology provides non-blocking I/O The asynchronous input and output mechanism provides an achievable basic mechanism for improving system performance.

Further, if it is detected that the login string does not exist in the verification data, the client determines that the login operation corresponding to the login request is in an abnormal state, and closes the monitoring thread. After the client determines that the login operation is in an abnormal state, the client outputs a login abnormality prompt message to prompt the user to log in abnormally.

Further, the step of converting the login string into a request message and sending the message to the server includes:

Step d: Perform a bit operation according to the length of the login string to recombine the login string to obtain the reassembled login string.

Further, the process of the client converting the login string into the request message and sending the message to the server may be: the client obtains the length of the login string, performs a bit operation according to the length of the login string in the for loop body, and reorganizes the login. String, get the refactored login string.

Step e: Perform modulo operation on the re-established login string and the preset prime number to obtain a data packet corresponding to the login string.

After the client obtains the re-established login string, the re-composed login string is modulo-operated with the preset prime number to obtain a data packet corresponding to the login string. In this embodiment, the preset prime number is 31. The prime number 31 is the length specified in Java. It can be understood that the preset prime number can be modified to other prime numbers in the Java code as needed.

In step f, the data packet is converted into a request message and sent to the server by using a preset protocol.

After the client obtains the data packet corresponding to the login string, the client converts the data packet into a request packet by using a preset protocol, and sends the request packet to the server. Among them, the default agreement can be Google Protobuf protocol or Apache Thrift protocol.

Step S30, after the server receives the request message, it is detected whether the request message meets the establishment rule for establishing a connection.

After receiving the request packet sent by the client, the server detects whether the request packet meets the establishment rule for establishing a connection.

Further, step S30 includes:

Step g: After receiving the request message, the server acquires a login string in the request message, and detects whether a pre-login in the database is found to be the same as the login string in the request message. Set the string.

Further, the process of detecting whether the request packet meets the establishment rule of the connection is: after the server receives the request message, the server parses the request message, obtains the login string in the request message, and detects in the database. Whether to find the same preset string as the login string in the request message. Among them, the database can be mysql database or RAM (Random-Access Memory, random access memory) memory.

In step h, if the preset character string is found, it is determined that the request message meets the establishment rule for establishing a connection.

If the same preset string as the login string in the request packet is found in the database, the server determines that the request message conforms to the connection rule for establishing the connection.

In step i, if the preset character string is not found, it is determined that the request message does not meet the establishment rule for establishing a connection.

If the same preset string as the login string in the request packet is not found in the database, the server determines that the request packet does not meet the connection rule for establishing a connection.

Step S40: If it is detected that the request message meets the establishment rule, establish a connection with the client.

After the server detects that the request message conforms to the establishment rule for establishing a connection, the server establishes a connection with the client. When a connection is established between the server and the client, the client can transmit data and communicate with the server.

In this embodiment, after the client detects the login request, the login request is sent to the server for login verification; when the server receives the login request, the login request is verified, and the verification data is returned to the client; when the client is verified according to the verification After the data is determined that the login operation corresponding to the login request is in a normal state, the login string in the verification data is obtained, and the login string is converted into a request message and sent to the server; when the server receives the request message, and the request message is detected, After the establishment rules for establishing a connection are met, the server establishes a connection with the client. By establishing login authentication before establishing a connection with the client, and establishing a connection after verification, the creation of useless connections is reduced, the burden on the server is reduced, and illegal elements are prevented from being connected after obtaining the IP address of the server. To the server, improve the security of the server.

Further, a second embodiment of the connection establishment method of the present application is proposed.

The second embodiment of the connection establishment method is different from the first embodiment of the connection establishment method. Referring to FIG. 2, the connection establishment method further includes:

Step S50: Generate first prompt information that successfully establishes a connection with the client, and send the first prompt information to the client, so that the client monitors after receiving the first prompt information. The status of the connection with the server.

After the server successfully establishes a connection with the client, the server generates a first prompt information for successfully establishing a connection with the client, and sends the first prompt information to the client. After receiving the first prompt information, the client outputs the first prompt information in its display interface, and monitors the connection state with the server after receiving the first prompt information. The manner in which the client outputs the first prompt information includes, but is not limited to, a text form and a voice form. For example, the client can output the text information of “successful connection” in its display interface to output the first prompt information.

The process of monitoring the connection status between the client and the server is as follows: the client creates a heartbeat packet, and starts a heartbeat packet after creating the heartbeat packet, and sends a timing task to the server through the heartbeat packet to monitor the connection state between the client and the server. . After the client starts the heartbeat packet, the client obtains the corresponding heartbeat log and stores the heartbeat log, so that the user determines whether the client and the server are in the connected state according to the heartbeat log. It should be noted that the client sends a scheduled task to the server through the heartbeat packet, that is, the client continuously sends a connection request to the server.

In this embodiment, after the server successfully establishes a connection with the client, the sending server and the client successfully establish a first prompt information of the connection to the client, and when the client receives the first prompt information, monitor the connection between the server and the server. Status so that client users can keep abreast of the connection status between the client and the server.

Further, a third embodiment of the connection establishment method of the present application is proposed.

The third embodiment of the connection establishment method is different from the first or second embodiment of the connection establishment method. Referring to FIG. 3, the connection establishment method further includes:

Step S60: If it is detected that the request message does not meet the establishment rule, the connection with the client is refused, and the second prompt information is generated.

If the server detects that the request message does not meet the establishment rule for establishing a connection, the server refuses to establish a connection with the client, and generates a second prompt message for establishing a connection failure.

Step S70: Send the second prompt information to the client, so that the client prompts the client user that the connection establishment fails according to the second prompt information.

After the server generates the second prompt information, the second prompt information is sent to the client. After receiving the second prompt information, the client outputs the second prompt information in its display interface to prompt the connection establishment failure between the user and the server according to the second prompt information. It should be noted that the output manner of the second prompt information output by the client includes, but is not limited to, a text form and a voice form. If the client can display in its display interface The text message "Connection failed" to output the second prompt message.

In this embodiment, when the server detects that the request packet does not meet the establishment rule, the second prompt information is sent to the client, so that the client prompts the connection establishment between the client user and the server to fail according to the second prompt information, so as to facilitate The user can decide whether to re-establish the connection as needed.
