Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Execution mode described in following exemplary embodiment does not represent all execution modes consistent with the application.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that some aspects of the application are consistent.
In order to complete understanding the application, refer to numerous concrete details in the following detailed description, but it should be appreciated by those skilled in the art that the application can realize without the need to these details.In other embodiments, be not described in detail known method, process, assembly and circuit, in order to avoid unnecessarily cause embodiment fuzzy.
According to the first aspect of the embodiment of the present application, provide a kind of many application layers webmaster concurrent access method.Fig. 1 is the schematic flow sheet of a kind of many application layers webmaster concurrent access method shown in the application one exemplary embodiment, and in Fig. 1, dotted line represents the transmission direction of data message.As shown in Figure 1, described method comprises:
Step S101, each local side nms process obtains the first socket respectively, and initiates connection request to local side access layer process.
Wherein, for the ease of design and the maintenance of local side program, local side software architecture is divided into successively local side access layer, local side business software layer, local side SDK software layer and local side operating system layer from top to bottom.Station-side operations system layer and operating system platform, such as, based on the operating system platform of LINUX; Local side SDK software layer is used for encapsulating local side SDK, when SDK changes, only need revise SDK layer, and the application code on upper strata is without the need to changing; Local side business software layer calls the interface of SDK, carries out business configuration, and stores business configuration; Local side access layer is used for carrying out communicating and transfer of data with multiple local side webmaster, manages, and carry out data encapsulation and interface abstraction to the access of multiple local side webmaster to multiple local side webmaster.After distinguishing hierarchy is carried out to local side software architecture, for the Concurrency Access of multiple local side webmaster, to solve primarily of local side access layer, communication port set up by local side access layer and multiple local side webmaster, carry out data communication, the communication of local side access layer and multiple local side webmaster is undertaken by local side access layer process and multiple local side nms process.Local side access layer is resolved after receiving the data of local side webmaster, then local side business software layer is delivered to, the difference process of local side webmaster type is completed in local side access layer, local side business software layer is just without the need to considering the type of local side webmaster again, only need carry out Business Processing, thus better can support the access of multiple local side webmaster.
Each local side nms process, when needs and local side access layer establish a communications link, obtains the first socket respectively, and initiates connection request to local side access layer process.Local side nms process obtains the first socket and initiates connection request to local side access layer process and can use conventional method, such as to the operating system (all illustrating with the operating system based on LINUX below) based on LINUX, call socket () to obtain socket descriptor, namely the first socket is obtained, and call connect () and carry out initiation connection request to local side access layer, to start to communicate with local side access layer.
Step S102, the readable state of local side access layer process poll local side access layer process socket, after obtaining the connection request of local side nms process according to the readable state of local side access layer process socket, obtain the second socket carrying out with local side nms process communicating, set up the communication connection of local side access layer process and each local side nms process.
Wherein, particularly, step S102 can comprise:
Step a1, local side access layer obtains local side access layer process socket and descriptor thereof, and the local side access layer process socket that initialization is corresponding, socket () can be called obtain local side access layer process socket descriptor, local side access layer process socket file path and the binding of local side access layer process socket descriptor under based on the operating system of LINUX;
Step a2, monitor the connection request of local side nms process, described local side access layer process socket descriptor is joined in descriptor set, listen () is called under based on the operating system of LINUX, can monitor the connection request of local side nms process, descriptor set is for storing socket descriptor;
Step a3, the state of query specification symbol collection, judge whether the state of descriptor set exists change, usually, interim descriptor set can be given by descriptor set assignment, use the state of the interim descriptor set of select () functional query under based on the operating system of LINUX, judge whether the state of descriptor set exists change by the return value of select (), select () if return value be greater than 0; there is change in the state of declarative description symbol collection;
Step a4, if the state of descriptor set exists change, travels through the state of all descriptors, judges whether the descriptor that existence changes, otherwise, return step a3, continue the state of query specification symbol collection;
Step a5: if the descriptor that existence changes, judges whether the descriptor that state changes equals described local side access layer process socket descriptor, namely equals the local side access layer process socket descriptor that local side access layer obtains;
Step a6, if the descriptor that state changes equals described local side access layer process socket descriptor, then there is local side nms process connection request, accept described local side nms process connection request, to obtain and local side nms process carries out the socket that communicates and descriptor, i.e. described second socket and descriptor thereof.Based under the operating system of LINUX, described socket descriptor of carrying out communicating with local side nms process can use accept () function to obtain, namely the socket descriptor obtaining carrying out communicating with local side nms process establishes the communication with local side nms process, the socket descriptor communicated with local side nms process is joined in descriptor set, return step a3, continue the state of query specification symbol collection, whether have other local side nms process connection requests to investigate.If the descriptor that the state traversed current changes is not equal to the local side access layer process socket descriptor that local side access layer obtains, then local side access layer process enters the process receiving the data that local side nms process sends.
Wherein, local side access layer process is by the change of poll local side access layer process socket state, after the connection request receiving local side nms process, set up the communication connection of local side access layer process and each local side nms process, monitor multiple local side nms process in the mode that I/O is multiplexing simultaneously, when receiving the connection request of local side nms process, set up the communication with local side nms process, when local side nms process sends data (when the readable descriptor traversed is not equal to the socket descriptor of local side access layer acquisition), start again to enter the process receiving data, thus there will not be the situation of communication blocking, fast response time, efficiency is high, the Concurrency Access of local side nms process can be realized.
Step S103, local side nms process becomes the first structure by needing the data encapsulation sent, and described first structure is sent to local side access layer process.
Step S104, after local side access layer process receives described first structure, transfer of data to the corresponding function interface parsing the transmission of local side nms process according to described first structure processes, the data encapsulation returned by function interface is the second structure, and described second structure is sent to local side nms process, the first structure is identical with the method for packing of the second structure.
Step S105, after local side nms process receives the second structure, resolves the data that described second structure obtains returning through function interface.
Wherein, during multiple local side nms process Concurrency Access, because the type of local side webmaster is different, the resource type transmitted, the action type related to is different, if processed respectively the data that the access of each local side nms process is transmitted simultaneously, data handling procedure will be made because processing procedure is inconsistent complicated and easily occur conflict and mistake, for the transmission data concurrent to multiple local side nms process unified process can be carried out, class wrapper is carried out to the data of local side nms process transmission, namely encapsulates data as structure.For local side nms process, sending to the data encapsulation of local side access layer process to be the first structure by needing, being then sent to local side access layer process.Local side nms process needs the data of transmission can be divided into webmaster type, action type, resource type and resource identification, therefore the first variable for representing webmaster type can be pre-defined at local side nms process, for representing the second variable of action type, for representing the ternary of resource type and the 4th variable for representing resource identification, the data needing to send are used described first variable by local side nms process, second variable, ternary and the 4th variable represent, described first variable will be used, second variable, ternary and four variable table show after data as the member of structure, be packaged into the first structure.Such as, be moduleType by webmaster type definition, various action type is defined as operType, is resType by resource type definitions, resource identification is defined as resId, and the value of each variable is concrete network type, action type, resource type and resource identification.Structural texture build uAlMsg, it is with moduleType, operType, resType and resID for member, and the structure of uALMsg type is the data of the local side nms process after encapsulation.When local side nms process sends data to local side access layer process, will directly send the structure of uAlMsg type.
Correspondingly, after local side access layer process receives described first structure, the method for packing according to the first structure is correspondingly resolved described first structure, parses the data that local side nms process sends.In order to resolve the data of encapsulation, and it is follow-up to encapsulation of data again during local side nms process return data, local side access layer process can pre-define the first variable for representing webmaster type, for represent action type the second variable, for representing the ternary of resource type and the 4th variable for representing resource identification, predefined variable is identical with method with the predefined variable of local side nms process with method.After local side access layer process receives described first structure, the first variable, the second variable, ternary and the 4th variable is parsed according to described first structure, such as, after local side access layer process receives the structure of the uALMsg type that local side nms process sends, extract moduleType, operType, resType and resID variable in structure, obtain webmaster type, action type, resource type and resource identification data.
After described first structure of local side access layer process parsing obtains corresponding data, transfer of data parsing obtained is to the function interface processed each data, described function interface is the interface of the function reception data of deal with data, the such as function of the deal with data of local side business software layer, comprises conventional data filtering function etc.Be about to resolve according to the first structure the first variable, the second variable, ternary and the 4th variable that obtain transfer to corresponding function interface and process.Through the data of function process, the meeting returned is needed to return to local side access layer process by function interface.After local side access layer process receives the data that function interface returns, then according to the method same with local side nms process encapsulation of data, data are encapsulated.The data returned by function interface are the second structure according to the first variable, the second variable, ternary and the 4th variable encapsulation.ModuleType, operType, resType and resID of such as being returned by function interface are encapsulated as the second structure of uALMsg type again.Local side access layer process is sent to local side nms process by encapsulating the second structure obtained again.
Wherein, after local side nms process receives the second structure of local side access layer process transmission, extract each variable in the second structure, obtain the numerical value of each variable, namely resolve described second structure and obtain through function process and the data returned by function interface.Such as, after local side nms process receives the second structure of uALMsg type, extract moduleType, operType, resType and resID variable in structure, obtain webmaster type and action type after treatment, resource type and resource identification data.
It should be noted that, local side nms process and the method for packing of local side access layer process to data are not limited in said method, also can use data encapsulation method or the self-defining data method for packing of other routine.
Wherein, after local side nms process is that local side access layer process establishes a communications link, if need to send data, then the data after encapsulation used the relevant function that sends to send, such as, under based on the operating system of LINUX, use send () function to send.After sending data, whether socket descriptor i.e. the first socket descriptor that the inquiry of local side nms process obtains is readable, such as use the first socket descriptor described in select () functional query whether readable, when the return value of select () is greater than 0, described first socket descriptor is readable.When described first socket descriptor is readable, illustrates that local side access layer process have sent data, then use receiver function, such as, accept the data of local side access layer process transmission based on the recv () function under the operating system of LINUX.For saving system processing resources, local side nms process is avoided unrestrictedly to inquire about described first socket descriptor whether readable to have judged whether that data can receive, when the result of described first socket descriptor of the double inquiry of local side nms process be all described first socket descriptor not readable time, just local side access layer process not return data is thought, and then close the first socket of local side nms process, namely close the communication with local side access layer process.
Wherein, for local side access layer process, communication connection is established with local side nms process, when entering the process receiving data, namely when the descriptor that the state traversed changes is not equal to the local side access layer process socket descriptor of local side access layer acquisition, obtain the readable byte number carrying out the socket (i.e. described second socket) communicated with local side nms process, if readable byte number is not 0, the data having corresponding local side nms process to send then are described, relevant receiver function is used to receive data, recv () is such as used to receive the data of local side nms process transmission.When local side access layer process sends data to local side nms process, use relevant transmission function to send described second structure to local side nms process, such as, use send () function to send.
If obtaining the readable byte number carrying out the socket communicated with local side nms process is 0, then illustrate that local side nms process has closed its first socket, namely the connection to local side access layer process is eliminated, now local side access layer process also closes the socket that current with corresponding local side nms process carries out communicating, and the socket descriptor of correspondence is removed from descriptor set, terminate the communication with local side nms process.
Step S106, after local side nms process and the process communication of local side access layer complete, local side nms process and local side access layer process close the socket of self correspondence respectively.
Wherein, after having communicated of local side nms process and local side access layer process, local side nms process and local side access layer process close the socket of self correspondence respectively, namely local side nms process closes the first socket of local side nms process, local side access layer process closes the second socket of local side access layer process socket and local side access layer process, removes communication connection between the two.
The socket that above-mentioned local side nms process relates to and the socket that local side access process relates to, be all preferably UNIX territory byte stream socket.UNIX territory socket is relative to conventional internet domain socket, only copy data, do not perform other process, there is higher communication efficiency, and UNIX territory byte stream socket is compared UNIX numeric field data report socket and is more suitable for local side nms process and the process communication of local side access layer and has the long characteristic be connected.

Step S205, local side access layer inquires about the readable state of described local side access layer process socket, after obtaining the connection request of local side nms process according to the readable state of local side access layer process socket, obtain the second socket carrying out with local side nms process communicating, set up the communication connection between local side access layer process and each local side nms process;
Step S206, the data needing to send use described first variable, the second variable, ternary and four variable table to show by local side nms process, by using described first variable, the second variable, ternary show with four variable table after data encapsulation become the first structure, and call the second interface described first structure be sent to local side access layer process;
