Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a first embodiment of the present invention provides a method for updating a white list, which is applied to a server, and the method includes:
and 101, when a new operation is detected, acquiring a new white list link, generating a first time stamp, and correspondingly storing the new white list link, the first time stamp and a new operational character.
Specifically, when a new operation is detected, a new white list link may be acquired, a white list identifier may be assigned to the new white list link, a first timestamp may be generated, and the white list identifier may be stored in correspondence with the new operator, the new white list link, and the first timestamp.
In this embodiment, the whitelist identifier, the newly added operator, the newly added whitelist link, and the first timestamp may be correspondingly stored in the local database.
Further, after the newly added white list link is obtained, the newly added operator, the white list identifier and the newly added white list link can be correspondingly stored in the first storage area, and the white list identifier and the first time stamp can be correspondingly stored in the second storage area. The first storage area and the second storage area may be located in an in-memory database.
And 102, when the deletion operation is detected, updating the operator corresponding to the deletion operation into the deletion operator, generating a second timestamp, and updating the timestamp corresponding to the deletion operation into the second timestamp.
Specifically, when the deletion operation is detected, the white list identifier may be acquired, the second timestamp may be generated, and the operation character and the timestamp which are stored by the operation character and the timestamp and correspond to the white list identifier may be modified into the deletion operation character and the second timestamp, respectively.
Further, when the deletion operation is detected, the operator corresponding to the white list identifier stored in the first storage area may be modified into a deletion operator, and the time stamp corresponding to the white list identifier stored in the second storage area may be modified into a second time stamp.
In addition, when the modification operation is detected, the white list identifier and the white list link can be acquired, a third timestamp is generated, and the white list link, the operator and the timestamp which are stored by the device and correspond to the white list identifier are modified into the acquired white list link, the modified operator and the third timestamp respectively.
Further, when the modification operation is detected, the whitelist link and the operational character corresponding to the whitelist identifier stored in the first storage area may be modified to the obtained whitelist link and the obtained operational character, respectively, and the timestamp corresponding to the whitelist identifier stored in the second storage area may be modified to a third timestamp.
The embodiment of the invention aims to set the corresponding operational character and the timestamp for each white list link, and when the white list is updated, the operational character and the timestamp corresponding to the white list link are updated, so that an operation log is not newly established, the accumulation of a large number of operation logs at a service end is avoided, and the writing and query performance of the service end is improved.
As shown in fig. 2, a second embodiment of the present invention provides a method for updating a white list, including:
For example, the white list link and the site name acquired by the server are "www.aaa.com" and "AAA website", respectively.
And step 204, the server returns error information, and the process is ended.
Wherein the first timestamp may be 13 bits of data and the database may be a Mysql relational database.
For example, the server allocates a white list identifier "10010" to the white list link "www.aaa.com", acquires the current time "2016071809155" as the first timestamp, and stores the white list identifier "10010", the site name "AAA website", the white list link "www.aaa.com", the first timestamp "2016071809155" and the newly added operator "a" in the Mysql relational database.
And step 206, the server side stores the white list identification, the white list link and the newly added operator as white list detail data to a first storage area.
The first storage area may be located in an in-memory database.
In this embodiment, the first storage area may be a Hash (Hash) of a Redis cache, the Hash includes a plurality of field-value pairs (field-value pair), the fields and values of the Hash may be words, integers, floating point numbers or binary data, and each field in the same Hash is unique and different.
For example, the white list link is "www.aaa.com," the white list is identified as "10010," the server saves the white list identification "10010," the white list link "www.aaa.com," and the newly added operator "a" as white list detail data into a hash of the Redis cache. The hashed fields are respectively a white list identifier, a white list link and an operator, and the corresponding values are "10010", "www.aaa.com" and "a".
And step 207, the server side stores the white list identifier and the first time stamp as white list index data into a second storage area, and the process is ended.
Wherein the second storage area may be located in the in-memory database.
In this embodiment, the second storage area may be a Sorted list (Sorted set) of the Redis cache, the Sorted list including a score field and a value. And the server side respectively takes the white list identification and the first time stamp as values and scoring fields to be stored in the ordered list.
For example, the server stores the white list identified as "10010" and the first timestamp "2016071809155" as white list index data into the ordered list of the Redis cache, where the score field of the ordered list is the first timestamp "2016071809155" and takes the value of "10010".
And step 208, the server side acquires the white list identification, the white list link and the site name.
For example, the white list identifier, the white list link, and the site name acquired by the server are "10010", "www.aaa111.com", and "AAA 111 website", respectively.
And step 210, the server returns error information, and the process is ended.
And step 211, the server acquires the current time as a third timestamp, and modifies the white list link, the site name, the operator and the timestamp corresponding to the acquired white list identifier in the database into the acquired white list link, the acquired site name, the modified operator and the third timestamp respectively.
For example, the server modifies the whitelist link "www.aaa.com", the site name "AAA website", the operator "a", and the timestamp "2016071809155" in the database corresponding to the whitelist identifier "10010" into "www.aaa111.com", "AAA 111 website", the operator "U", and the timestamp "2016071811352", respectively.
In step 212, the server side queries the white list detail data containing the white list identifier in the first storage area according to the obtained white list identifier, and updates the white list link and the operator in the queried white list detail data to the obtained white list link and the modified operator respectively.
For example, the white list acquired by the server is identified as "10010", the white list detail data queried in the first storage area includes the white list identification "10010", the white list link "www.aaa.com" and the operator "a", and the server modifies the white list link "www.aaa.com" and the operator "a" in the queried white list detail data into "www.aaa111.com" and the operator "U", respectively.
For example, the white list acquired by the server is identified as "10010", the white list index data queried in the second storage area includes the white list identification "10010" and the timestamp "2016071809155", and the server modifies the timestamp "2016071809155" into the timestamp "2016071811352".
In step 214, the server obtains the white list identifier.
For example, the white list acquired by the server is identified as "10010".
And step 216, the server returns error information, and the process is ended.
And step 217, the server acquires the current time as a second time stamp, and modifies the operator and the time stamp corresponding to the acquired white list identifier in the database into a deleted operator and the second time stamp respectively.
For example, the server modifies the operator "a" and the timestamp "2016071809155" in the database corresponding to the white list identifier "10010" to the operator "D" and the timestamp "2016071811352", respectively.
In step 218, the server queries, according to the obtained white list identifier, the white list detail data containing the white list identifier in the first storage area, and updates an operator in the queried white list detail data to a delete operator.
For example, the white list acquired by the server is identified as "10010", the white list detail data queried in the first storage area includes the white list identification "10010", the white list link "www.aaa.com" and the operator "a", and the server modifies the operator "a" in the queried white list detail data into the operator "D".
For example, the white list acquired by the server is identified as "10010", the white list index data queried in the second storage area includes the white list identification "10010" and the timestamp "2016071809155", and the server modifies the timestamp "2016071809155" into the timestamp "2016071811352".
In the second embodiment of the present invention, a corresponding operator and a timestamp are set for each white list link, and when a white list is updated, the operator and the timestamp corresponding to the white list link are updated, and an operation log is not newly created, so that a large amount of operation logs are prevented from being accumulated at a server, and writing and query performance of the server is improved. In addition, the white list detail data and the white list index data are stored in the memory, so that the white list of the client side can be rapidly synchronized.
As shown in fig. 3, a third embodiment of the present invention provides a method for processing a white list update request, including:
The maximum timestamp is the timestamp with the maximum value currently stored by the server.
For example, the server returns a maximum timestamp of "2016071809155" to the client.
Wherein the second storage area may be located in the in-memory database.
In this embodiment, the second storage area may be an ordered list of the Redis cache, the ordered list including a scoring field and a value.
For example, the timestamp progress information in the white list update request is "2016070607349", the server queries timestamps greater than "2016070607349", i.e., "2016070819343", "2016071023190", and "2016071809155", from the ordered list, and acquires white list identifications "10001", "10009", and "10005" corresponding to the queried timestamps.
The first storage area may be located in an in-memory database.
In this embodiment, the first storage area may be a hash of a Redis cache, the hash includes a plurality of field value pairs, the field and value of the hash may be words, integers, floating point numbers or binary data, and each field in the same hash is unique and different.
For example, the service side queries corresponding links and operators of the white list from the hash according to the obtained white list identifications "10001", "10009" and "10005", wherein the links and operators of the white list corresponding to "10001" are "www.bbb.com" and "a", the links and operators of the white list corresponding to "10009" are "www.ccc.com" and "U", and the links and operators of the white list corresponding to "10005" are "www.aaa.com" and "D", respectively, and sends the links, operators and the white list identifications of the white list to the client side as white list increment data.
In the third embodiment of the invention, the corresponding operational character and the timestamp are set for each white list link, and when the white list is updated, the operational character and the timestamp corresponding to the white list link are updated, so that an operation log is not newly established, the accumulation of a large number of operation logs at the server is avoided, and the writing and query performance of the server is improved. In addition, the white list detail data and the white list index data stored in the memory are read, and the white list increment data are sent to the client, so that the white list of the client can be quickly synchronized.
As shown in fig. 4, a fourth embodiment of the present invention provides a method for synchronizing a white list, including:
in step 401, the client receives the white list identifier, the white list link and the operator from the server.
Specifically, when the operator is a new operator, the client may store the corresponding whitelist identifier and the whitelist link to the local database. When the operational character is a deletion operational character, the client can judge whether the received white list identifier is stored in the local database, and if so, delete the white list identifier stored in the local database and the link corresponding to the white list identifier; otherwise, the flow ends.
In addition, when the operator is a modification operator, the client modifies the white list link corresponding to the received white list identification, which is stored by the client, into the received white list link.
In this embodiment, when the operational character is a modified operational character, the client may determine whether the received white list identifier is stored in the local database, and if so, modify a link corresponding to the received white list identifier in the local database into the received white list link; otherwise, the received white list link and the white list identification are added to a local database.
The client in the fourth embodiment of the invention updates the white list according to the received operator, and does not pull the intermediate data synchronization client any more, thereby removing a large amount of redundant data and improving the operating efficiency of the client.
As shown in fig. 5, a fifth embodiment of the present invention provides a method for synchronizing a white list, including:
And the white list updating request comprises timestamp progress information.
For example, the white list update request includes timestamp progress information "2016070607349".
The white list incremental data comprises one or more white list links and white list identifications and operators corresponding to the white list links.
In step 503, the client updates the timestamp progress information stored by the client to the received maximum timestamp.
For example, when the received maximum timestamp is "2016071809155", the client updates the timestamp progress information "2016070607349" stored by itself to "2016071809155".
In step 505, the client adds the current link and the white list identifier corresponding to the current link to the local database, and performs step 511.
In step 507, the client modifies the link corresponding to the white list identifier in the local database into the current link according to the white list identifier corresponding to the current link, and executes step 511.
In step 508, the client adds the current link and the white list identifier corresponding to the current link to the local database, and performs step 511.
The client in the fifth embodiment of the invention updates the white list according to the received operational characters, and does not pull the intermediate data synchronization client any more, thereby removing a large amount of redundant data, reducing the times of operating the local database and improving the operating efficiency of the client.
