The embodiment is particularly suitable for processing the situation that a user applies for a card number in a large quantity.
s102, the card number application request is distributed to one or more nodes, wherein each node has non-repeated number field information.
In the embodiment, the operation of subsequently and efficiently generating a large number of card numbers is realized by setting a plurality of callable nodes with non-repeated number field information.
Note that S102 may be completed by the client or the server. When S102 is completed by the client, the nodes refer to a plurality of nodes located at the client, and when S102 is completed by the server, the nodes refer to a plurality of nodes located at the server. Distributing the card number application request to multiple nodes may improve processing efficiency.

The BIN value corresponding to the happy honoured guest card is 000006, and the BIN value can be distributed to the node 11, and the number segment information corresponding to the node 11 is 0/1000.
TABLE 1 information List
S103, obtaining corresponding card number basic information and a corresponding card number segment value through the node receiving the card number application request, and generating the card number according to the corresponding card number basic information and the corresponding card number segment value, wherein the obtained card number segment values corresponding to the same card number basic information are different.
Because the number segment information corresponding to each node is not repeated, the nodes can obtain different number segment values in the corresponding number segment in parallel based on the number segment information of the nodes, thereby ensuring that a plurality of non-repeated card numbers can be generated simultaneously and efficiently.
It should be noted that the above operations may be performed by the client, that is, the client may first obtain the information list from the server, then determine the callable nodes according to the information list, then distribute the obtained card number application request to one or more callable nodes, and finally generate the card number according to the obtained corresponding card number basic information and the obtained number segment value by the node that receives the card number application request, as shown in fig. 1 b; the above operations may also be performed by the server, that is, the server determines a plurality of callable nodes according to the information list stored by the server, then distributes the obtained card number application request to one or more callable nodes, finally generates a card number according to the obtained corresponding card number basic information and the obtained number segment value by the node that receives the card number application request, and then returns the generated card number to the client, as shown in fig. 1c, and finally executes the card issuing operation by the client.
According to the method for generating the card number, the different number segment values in the number segment are obtained in parallel through the plurality of nodes, and the card number is generated according to the obtained different number segment values and the corresponding card number basic information, so that the generated card number is not repeated, the problem of performance bottleneck during a large number of card issuing is solved, and the card issuing efficiency is improved.
Fig. 2 is a flow chart of a method of generating a card number according to an embodiment of the present application. The embodiment is described from the side of the node receiving the card number application request, wherein the node receiving the card number application request can be positioned at the side of the server or the side of the client; for each node receiving the card number application request, the process of generating the card number is executed as shown in fig. 2, and includes:
S201, the information list is inquired to obtain first data corresponding to the basic information of the current card number, and a current number segment value is obtained according to the first data and the number segment information corresponding to the current node.
specifically, the current node determines whether first data exists in the local information list, and if so, the assigned number segment value is used as the current number segment value, and then the assigned number segment value is subjected to an addition operation. For example, assuming that the segment information corresponding to the current node is 0 to 1000, and the current card number basis information includes mettesland and ordinary membership cards, if the local information list has the first data, i.e., BIN value, of the ordinary membership card corresponding to mettesland, and it is assumed that 000001, the assigned segment value in the segment information corresponding to the first data is used as the current segment value, and it is assumed that the assigned segment value is 3, 3 is used as the current segment value, and then the assigned segment value is set to 4, so that when the current node receives the next request for applying for the ordinary membership card of mettesland, it may use 4 as the segment value corresponding to the request, and similarly, it is necessary to set the assigned segment value to 5, thereby ensuring that the obtained segment values corresponding to the same card number basis information are different.
In addition, in order to ensure that the BIN value corresponding to the card number basic information included in the card number application request is stored in the information list, in this embodiment, after the server receives the card number application request sent by the client, the card number basic information included in the card number application request is obtained, if the local information list does not have the first data, that is, the BIN value, corresponding to the card number basic information, for example, the BIN value of the ordinary membership card corresponding to mestra, the corresponding first data is allocated, and the allocated first data and the corresponding card number basic information are written into the information list; in addition, after the client sends an information query request to the server, the server can return an information list containing the distributed first data and the corresponding card number basic information to the client; therefore, the BIN value corresponding to the card number basic information contained in the current card number application request is ensured to be contained in the information list stored at the server side or the client side.
in this embodiment, the current node may determine whether the assigned number segment value is smaller than a predetermined threshold, and if so, take the assigned number segment value as the current number segment value. And when the assigned number segment value is determined to be larger than or equal to the preset threshold value, inquiring whether an available number segment exists in the information list, if the available number segment exists, obtaining the available number segment, if the available number segment does not exist, generating new first data, and setting the assigned number segment value corresponding to the new first data as the initial value of the corresponding number segment. For example, if the number segment information corresponding to the current node is 0-1000 and the predetermined threshold is 900, if the assigned number segment value is 800, which is smaller than the predetermined threshold, the current number segment value is 800. If the assigned number segment value is 950 and is greater than the preset threshold value, the information list is inquired, and since the information list can also contain the assigned number segment information, the maximum available number segment information and the like of each node, whether the current node has available number segments or not can be judged according to the information, if the available number segments still exist, the available number segments are obtained, and the available number segments are used as the number segment information of the current node. If there is no available number segment, new first data is generated such as: 000002 and setting the assigned number segment value corresponding to the new first data as the start value 0 of the number segment 0-1000 corresponding to the current node. The purpose of this is: when the assigned number segment value of the current node is larger than a preset threshold value, namely the available number segment value of the current node is few, more available number segment values are obtained in advance, and the efficiency of obtaining the number segment value by the node is improved.
s202, check bit information is obtained.
After the current number segment value is obtained according to the first data and the corresponding number segment information, the current node can obtain check bit information so as to ensure the legality of the card number.
S203, generating the card number according to the obtained first data, the current number segment value and the check digit information.
After obtaining the check digit information, the current node may generate the card number according to the obtained first data, the current number segment value, and the check digit information. Specifically, a schematic diagram of generating a card number is shown in fig. 3, wherein the card number base information may include card issuer information and card type information. The first data may be obtained through the card issuer information and the card type information. The card issuing element may include: first data (BIN value), a random number segment (number segment value), and a check bit. The card number can be generated by the three card issuing elements.
according to the method for generating the card number, the different number segment values in the number segment are obtained in parallel through the plurality of nodes, and the card number is generated according to the obtained different number segment values and the corresponding card number basic information, so that the generated card number is not repeated, the problem of performance bottleneck during a large number of card issuing is solved, and the card issuing efficiency is improved.
