Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The invention aims to solve the problem that the interface failure or the interface calling failure is easily caused by the overlong decryption time of the existing interface parameter decryption method, and provides a parameter decryption method and a system based on a multimedia system, wherein the technical scheme is summarized as follows: starting multithreading, and initializing a starting thread pool and a Redis cache; storing a direct field into a Redis cache in a Key-Value form, wherein the direct field is selected according to different multimedia systems; acquiring a plurality of encryption parameters of an interface, and correspondingly putting the encryption parameters into a plurality of threads; in each thread, judging whether the corresponding encryption parameter is a direct field, if so, decrypting the encryption parameter in a Redis cache, otherwise, decrypting the encryption parameter in a decryption system; and assembling a new object by all the decrypted parameters, and performing interface operation.
Firstly, when a project is started, multithreading and Redis cache services are started, and direct fields are set according to different systems and are used for distinguishing indirect fields. The direct field needing to be stored in the Redis cache is a large number of repeated encrypted fields, is easy to decrypt slowly and meaningless to decrypt repeatedly, and is stored in the Redis cache in the form of key and value according to the field name, and the fields can be guaranteed not to be leaked due to the safety guarantee of the Redis cache and the benefit of field time effectiveness setting. When an interface with large data volume encryption parameters is acquired by a tangent plane function, separating the fields of the parameters, and simultaneously putting the fields into threads, wherein each thread firstly judges whether the field is a direct field, if so, the Redis cache is removed, if the Redis cache has no value, the decryption method is removed, if the field entering the multithreading is not a direct field, the decryption method is directly removed, the terminal reserves a general object to assemble the decrypted parameters, and the interface operation is carried out after the assembly.
Examples
The parameter decryption method based on the multimedia system in the embodiment of the invention, as shown in fig. 1, comprises the following steps:
step S1, starting multithreading, and initializing a starting thread pool and a Redis cache;
when multi-threading is started, the maximum number of threads can be set, such as 5 threads, which can be used for a parameter decryption process and an interface operation process;
step S2, storing a direct field in a Redis cache in a Key-Value form, wherein the direct field is selected according to different multimedia systems;
specifically, byte fields which need to exist in the Redis cache are set (for example, "createdUser" and "systemType" are set as direct fields), and the direct fields can be selected according to different multimedia systems; the direct field needing to be stored in the Redis cache is a large number of repeated encrypted fields, the decryption is slow, and the repeated decryption has no meaning, and the method for storing the direct field in the Redis cache in the form of Key-Value can comprise the following steps:
and storing the direct field into a Redis cache by taking the encrypted Value of the direct field as an identification Key and the decrypted Value of the direct field as Value.
Optionally, step S2 may further include: and deleting the direct fields stored in the Redis cache after a preset time. For example, the aging is set to be 2 hours, and the data stored in the Redis cache is cleaned after 2 hours, so that the safety of the data is ensured.
Step S3, acquiring a plurality of encryption parameters of an interface, and correspondingly putting the encryption parameters into a plurality of threads;
it can be understood that a plurality of encryption parameters of the interface are obtained, for example, the interface is "/test/save", the encryption parameters are { "name": xxx "," content ": xxx", "age": xxx "," createdUser ": xxx", "systemType": xxx ". All parameters are put into the threads, e.g. 5 parameters in total in the example, and then directly enter 5 threads in the thread pool.
It should be noted that, when there are a plurality of encryption parameters, the number of which is greater than the number of threads, the encryption parameters may be uniformly distributed to the plurality of threads, and the plurality of threads sequentially execute a decryption process on the distributed encryption parameters.
Step S4, in each thread, judging whether the corresponding encryption parameter is a direct field, if so, decrypting the encryption parameter in the Redis cache, otherwise, decrypting the encryption parameter in a decryption system;
specifically, whether the parameter is a direct field is judged, for example, "createdUser" and "systemType" are the direct fields, the direct field is set to typep to 1, and the encrypted parameter is decrypted in the Redis cache; the indirect field sets type to 2, and the encryption parameter is decrypted in the decryption system.
Wherein, the decrypting the encryption parameter in the Redis cache specifically comprises:
and taking the encrypted Value of the encrypted parameter as an identification Key, judging whether the identification Key exists in a Redis cache, if so, acquiring a decrypted Value corresponding to the identification Key, and otherwise, decrypting the encrypted parameter in a decryption system.
Optionally, the method of this embodiment further includes: if the encryption parameter is a direct field and the identification Key of the encryption parameter does not exist in the Redis cache, the encryption parameter is decrypted in a decryption system, and then the decrypted encryption parameter is stored in the Redis cache in a Key-Value form.
Specifically, when the encryption parameter is a direct field and the identification Key of the encryption parameter does not exist in the Redis cache, it indicates that the encryption parameter is not stored in the Redis cache in advance, and in order to improve the subsequent parameter decryption efficiency, the encryption parameter is decrypted and then stored in the Redis cache in a Key-Value form, so that the subsequent same encryption parameter can be decrypted in the Redis cache. The specific method for storing the encrypted parameters into the Redis cache in a Key-Value form after decryption comprises the following steps:
and taking the encrypted Value of the encrypted parameter as an identification Key and the decrypted Value of the encrypted parameter as Value, and storing the direct field into a Redis cache.
And step S5, assembling all the decrypted parameters into a new object, and performing interface operation.
Specifically, the terminal reserves a general object to assemble the decrypted parameters, and simultaneously stores all the set fields needing to enter the Redis cache into the Redis cache in an increment mode, namely, the fields are repeatedly not stored and are not stored. Therefore, the decryption system can be used for fast decryption first each time the interface is accessed, and the decryption cannot be timed out.
Based on the above technical solution, this embodiment further provides a parameter decryption system based on a multimedia system, as shown in fig. 2, including: the device comprises a starting unit, a storage unit, an acquisition unit, a decryption unit and an assembly unit;
the starting unit is used for starting multithreading, initializing a starting thread pool and a Redis cache;
the storage unit is used for storing a direct field into a Redis cache in a Key-Value form, and the direct field is selected according to different multimedia systems;
the acquiring unit is used for acquiring a plurality of encryption parameters of an interface and correspondingly putting the encryption parameters into a plurality of threads;
the decryption unit is used for judging whether the corresponding encryption parameter is a direct field or not in each thread, if so, decrypting the encryption parameter in a Redis cache, and otherwise, decrypting the encryption parameter in a decryption system;
and the assembling unit is used for assembling all the decrypted parameters into a new object and performing interface operation.
It can be understood that, since the parameter decryption system based on the multimedia system according to the embodiment of the present invention is a system for implementing the parameter decryption method based on the multimedia system according to the embodiment, for the system disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is simpler, and the related points can be referred to the partial description of the method.
