In the embodiment of the invention, the client comprises electronic equipment such as a mobile phone, a tablet personal computer, a computer and the like, the electronic equipment generally has the requirement of logging in an account number on a front-end login page, and when the account number is logged in, an account number and a password are input on the front-end login page, and an authentication code is also required to be input to indicate that a real person logs in the account number, so that the condition of maliciously using a machine or a program to perform batch automatic login operation is prevented.
In the embodiment of the present invention, when receiving a verification login request sent by a client, a verification server generates a verification code of the verification login request, a verification code picture corresponding to the verification code, and a verification code identifier, which specifically includes the following steps: generating the first verification code and a corresponding verification code identifier; and carrying out picture conversion on the first verification code and carrying out visual confusion processing on the converted picture to generate the verification code picture. The random code generator may generate a fixed number of character codes, for example, 4 character codes and more character codes, which are not limited herein, and the character codes include upper and lower case letters, symbols, Chinese characters, and the like. The visual confusion processing is also capable of performing single amplification, reduction, different color processing and the like on the character codes in the picture so as to increase the safety of the verification code. The ID number is unique and is used to identify the verification code, so as to search for the corresponding verification code in the buffer by using the ID number, wherein the verification code identification can be determined according to the time of verification code generation, and is not limited herein.
Step S12: and sending the first verification code and the corresponding verification code identification to a buffer for associated storage.
In the embodiment of the invention, after the verification code and the corresponding verification code identifier are generated, the verification code and the corresponding verification code identifier can be stored in the buffer in an associated manner. The buffer may store a large number of different verification codes and corresponding verification code identifiers in a unified time to process a large number of verification code verification operations in the same time, and the buffer may set a retention time of the verification codes, that is, a failure time of the verification codes, which may be set to 2 minutes or more, for example, which is not limited herein.
Step S13: and coding the verification code picture, generating a corresponding picture code, combining the picture code with a corresponding verification code identifier to generate a verification code message, and sending the verification code message to the client.
In the embodiment of the present invention, after the verification code server generates the verification code picture, the verification code picture is encoded, where the encoding may be base64 encoding, so as to obtain the picture code of the verification code picture, and the picture code and the verification code identifier are combined into the verification code message. When the verification code message is combined, the verification code identifier can be inserted into the picture code according to a preset rule to increase the security of the verification code message and prevent the message from being intercepted and cracked, for example, the verification code identifier can be divided into a plurality of sections according to preset bits, inserted into a preset position of the picture code, and an identifier position is added for marking. The verification code message is an interface message in a json format.
In the prior art, a method for acquiring an authentication code identifier by using a cookie (browser cache) cannot acquire the authentication code identifier when a domain name or a port of a front-end page is different from that of a back-end server, that is, under the condition of cross-domain, so that authentication cannot be completed. In the embodiment of the invention, the verification code identifier combination is added into the picture code to generate the verification code message and the verification code message is sent to the client, so that the client does not need to acquire the verification code identifier from the cookie, the problem that the verification code identifier cannot be acquired in a cross-domain mode is solved, and the user experience is improved.

In the embodiment of the invention, the verification server can receive the verification code sent by the client and the verification code identification corresponding to the verification code. After receiving the verification code identification sent by the client, the verification server enters the buffer by using the verification code identification for matching so as to obtain the corresponding verification code in the buffer. The process of entering the cache for matching by using the verification code identifier may be implemented by using an algorithm or an application program, for example, an application program may be set in the verification server, and after the application program obtains the verification code identifier sent by the client, the application program may enter the cache by using the verification code identifier to search for the verification code associated with the verification code identifier. When the associated verification code is not found in the buffer, the verification code is expired, and the verification server can send a verification code expiration prompt to the client.
Step S25: and judging whether the second verification code is consistent with the corresponding verification code in the buffer.
Step S26: and when the second verification code is consistent with the corresponding verification code in the buffer, the verification is successful and a verification success prompt is sent to the corresponding client.
In the embodiment of the invention, when the verification code sent by the client is consistent with the corresponding verification code in the verification server, the verification is successful, wherein the verification server can receive the account number and the password sent by the client and verify the verification code, and the client is allowed to log in when the account number and the password are both correct.
In the embodiment of the present invention, the process of determining whether the verification codes are consistent may be implemented by using an algorithm or an application program, for example, an application program for determining the verification codes may be set in the verification server, and after receiving the verification codes of the client and finding the corresponding verification codes in the buffer, the application program may compare the two verification codes to determine whether the two verification codes are consistent.
Step S27: and when the second verification code is inconsistent with the corresponding verification code in the buffer, sending a verification failure prompt to the corresponding client.
In the embodiment of the invention, when the verification code sent by the client is inconsistent with the corresponding verification code in the buffer, the verification server can generate the verification title to the corresponding client, prompt the client to input again or prompt the client to refresh the verification code. When the client refreshes the verification code, the verification server generates a new verification code and a corresponding identifier and picture, and the steps are repeated, and the invalid verification code in the buffer is automatically deleted.
