Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
As shown in Figure 1, video cloud platform API Access frequency control method of the present invention the following steps are included:
Step 1, the flexible control based on different user account need the core logic of control being transferred to service logic
Layer, request filter element intercept the HTTP API Access request of all users；
Step 2, request filter element obtain the User ID in HTTP request parameter, carry out parameter and deliver for a check, if do not met
Then direct denied access；
Step 3 judges whether user's access is more than visitation frequency, if user alreadys exceed the visitation frequency of restriction,
It directly returns or directly refuses；If user is not above the visitation frequency of restriction, which passes request
The business logic processing unit for passing rear end is handled；
Step 4, the current accessed for obtaining user into distributed caching according to User ID counts, if the value is not present,
The value is then denoted as 1；
Step 5 directly allows this if the value is not present according to the maximum access times that User ID gets user
Access passes through；
Current accessed is counted and carries out numeric ratio pair with maximum access count by step 6；
The request is then forwarded the request to Service Processing Unit and carried out by step 7 if access is not up to the upper limit
Processing；
Step 8 requests the direct denied access of filter element if the access reaches the upper limit；
Step 9, after the unit time, current request technology can be zeroed out by request control unit.
As shown in Fig. 2, when visitation frequency Fi lter (filter) is needed to each request video management API Subscriber Unit
In access times and maximum access times are counted in each Subscriber Unit time, since video cloud platform accesses user
It is numerous, it needs quickly accurately to find the current count value needs of some access user and is ensured by special mechanism,
It will use two Hash dictionaries difference storage cell times access times and maximum access times in the present embodiment.Hash dictionary
It is to look for fastest data structure, is well suited for being used in finding from a large amount of key values to some key and corresponds to numerical value.At this
In embodiment, we use key of the video cloud platform for unique ID of each user distribution as Hash dictionary, access count work
For the value of Hash dictionary, so that it may quickly find the current access count of some User ID.Such as: user A accesses API,
Filter can search the corresponding current count key count_key_A of ID ID_A of user A, be that key is being worked as by count_key_A
Current accessed is found in preceding access count Hash dictionary counts count_A.Maximum access count is calculated by identical method
Key max_count_key_A and value max_count_A.
Referring finally to count_A whether more than max_count_A, if it does, not allowing then to access, returned to client wrong
Accidentally.
In the case where allowing access in the case where count_A is less than max_count_A, system is needed A pairs of user
The current accessed answered, which counts, adds one, and the value added is newly stored into Hash table.
When being carried out to count_A plus a deposit, it should be noted that the user may also exist there are also other requests at this time
API is accessed, if other in the dictionary may be override if putting back to again out from value in Hash dictionary and requested
Change to the value.So system needs to guarantee the atomicity of count_A, guarantee that it is thread-safe；It herein can be by
The characteristic of high-level language, such as count_A is declared as the AtomicInteger in Java, call its getAndIncrease
Method can add one to it in the case where guaranteeing thread-safe.
What system needed to control is the video management API Access frequency in the unit time, and it is fixed that this means that we need
Phase is zeroed out the access times of statistics.Video cloud platform API system will start a timer in this embodiment, every
The operation of unit time t is primary, empties all current accesseds in Hash dictionary and counts.So just can guarantee can control the unit time
Interior visitation frequency.
As shown in figure 3, in actual use situation, platform generally requires to service due to the publicly-owned characteristic of video cloud platform
Mass users have to be the distributed request to cope with magnanimity this requires video cloud platform API.Divide by API system
After cloth, because multiple programs need share and access to count, current accessed was counted into Hash dictionary and maximum access meter originally
Number Hash dictionary is stored in the mode in local memory and is just no longer applicable in.In distributed environment, the present embodiment will be used
Redis (reaffirming) stores access count, key assignments class storing data library redis (reaffirming) outstanding as one, have it is high simultaneously
Hair and distributed characteristic.Also, the characteristic of automatic expired (expire) can be set using redi s (reaffirming) all keys,
It can not have to periodically empty access count in program again, more accurate access control can be reached.
As shown in figure 4, needing to provide using redis (reaffirming) when (reaffirming) that access count increases to redis
Incr operation, just can guarantee the atomicity of the data manipulation in multithreading.
Redis has been applied among these and (has reaffirmed) the automatic expiration mechanism of key to guarantee emptying automatically for access count, has been come
Achieving the purpose that frequency control, the maximum visitation frequency of each video cloud platform user is recorded in redi s (reaffirming),
It can modify in video cloud platform management system, change each user's maximum limitation in real time, achieve the purpose that flexibly to control.
In conclusion the present invention can flexibly control the frequency of each user, and can be arranged into extension at any time
In cluster, video cloud API system can be supported to expand to cluster, increase node as needed, it can be at any time after deployment is completed
The frequency configuration of each user is modified, characteristic easy to maintain can flexibly be expanded by reaching.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.
