Be based on serial traffic link shown in Fig. 3 below with the first user and second user calls portion identical respectively
The technical solution of this specification is described in detail in target service data instance.
Fig. 3 is referred to, the first user and second user can be linked into above-mentioned string by service customer end (such as APP)
Service sub-system A in row service link initiates the data tune for being directed to above-mentioned target service data to above-mentioned service sub-system A
With.
Wherein, user initiates the triggering mode of the data call to above-mentioned target service data by service customer end,
Without being particularly limited in this specification；It in practical applications, can be by being mentioned in the user interface of above-mentioned service customer end
It is realized for the operation entry for initiating data call；
For example, the first user and second user are based on above-mentioned serial traffic using above-mentioned target service data as order data
Link for calling an identical order data, can provide one for triggering looking into for order inquiries in above-mentioned client
Button is ask, user can input order number to be checked by service customer end, then by operating the inquiry button, initiate needle
Data call inquiry to the order data of order number instruction.
Continuing with referring to Fig. 3, target industry is directed to when above-mentioned subsystem A (i.e. head end subsystem) receives the first Client-initiated
After the data call request for data of being engaged in, which can be requested to continue up the downstream subsystem for stating serial traffic chain road
System is issued, and data call request is further issued to subsystem B.And subsystem B is in the number for receiving subsystem A and issuing
After call request, identical movement can be executed, continues data call request to be issued to subsystem C, and so on, directly
Above-mentioned serial traffic link is relied on to data call request, has finally been passed through end subsystem.
When above-mentioned subsystem C (i.e. end subsystem) receives the data call to come via above-mentioned serial traffic link transparent transmission
After request, relevant data service can be called, relevant service database is accessed and therefrom inquires the first user and need to call
Target service data.
Wherein, it should be noted that the first Client-initiated is directed in the data call request of above-mentioned target service data,
The identification information of above-mentioned target service data can specifically be carried.
For example, above-mentioned identification information specifically can be O/No. so that above-mentioned target service data are order data as an example.
And above-mentioned subsystem C is when calling relevant data service, specifically the data call can be requested in carry
The identification information of the target service data therefrom inquires above-mentioned target service as search index, from relevant service database
Data.
After inquiring the target service data that the first user needs to call referring to Fig. 3, subsystem C, Ke Yijin
One step returns the target service data to the upstream subsystem of above-mentioned serial traffic link, by the target service data into
One step is back to subsystem B.And subsystem B can be executed identical dynamic after the target service data for receiving subsystem C passback
Make, which is continued to be back to subsystem A, and so on, until the target service data rely on above-mentioned string
Row service link has finally passed back to head end subsystem.
And for subsystem A, by the first Client-initiated for above-mentioned target service data data call request into
After one step is handed down to downstream subsystem, it can determine immediately whether to receive the mesh that subsystem C is returned by above-mentioned service link
Mark business datum.
Wherein, in a kind of embodiment shown, subsystem A is in the target for determining whether to receive subsystem C passback
When business datum, it can specifically be realized by introducing passback timeout mechanism.
In this case, subsystem A can preset the overtime duration of a passback, and subsystem A is used by first
After the data call request for above-mentioned target service data that family is initiated further is handed down to downstream subsystem, it can open immediately
Dynamic timer starts timing, and the timing result based on the timer, to be confirmed whether within the passback time-out duration, receives
The target service data returned to subsystem C；
If having received the target service data of system C passback in the passback time-out duration, show above-mentioned serial traffic
Each downstream subsystem of chain road is normal condition, and the mesh for having received subsystem C return can be confirmed in subsystem A at this time
Mark business datum.
, whereas if not receiving the target service data of system C passback in the passback time-out duration, show above-mentioned serial
In downstream subsystem in service link, it is understood that there may be malfunctioning node；For example, the corresponding server delay machine of subsystem, or
Since network failure leads to packet loss, normal data back can not be carried out；At this point, subsystem A can be confirmed and have received subsystem
The target service data that the C that unites is returned.
Certainly, in practical applications, downstream subsystem of the subsystem A on above-mentioned serial traffic chain road meets with downstream
It, can also actively upstream subsystem reporting fault message when subsystem fault.
For example, subsystem B by above-mentioned data call request be further issued to subsystem C after, if subsystem C return
Pass the target service data for not receiving subsystem C passback in overtime duration；Alternatively, detecting subsystem by other detection means
It is currently at the inaccessible state of link between C and subsystem B, may determine that subsystem C breaks down at this time, subsystem B can
The failure message that a prompt subsystem C breaks down is returned with subsystem A upstream.
In this case, above-mentioned subsystem A may also determine whether to receive in the overtime duration of passback above-mentioned serial
Service link is taken up an official post the failure message of alien's system passback；If subsystem A is received in above-mentioned passback time-out duration
The failure message that downstream subsystem breaks down can determine the target service number for not receiving the passback of end subsystem immediately
According to；, whereas if subsystem A does not receive the failure message that downstream subsystem breaks down in above-mentioned passback time-out duration,
It can start to determine whether to receive the target service data that subsystem C is returned within above-mentioned passback time-out duration again at this time.
In this way, the failure message that can will be returned based on downstream subsystem, to determine whether receiving son
The mechanism of the target service data of system C passback is returned to by introducing passback timeout mechanism to determine whether to receive subsystem C
The mechanism of the target service data of biography, is further supplemented, system erroneous judgement can be effectively prevented.
After the target service data for having acknowledged receipt of subsystem C passback referring to Fig. 3, subsystem A, show above-mentioned
Each downstream subsystem of serial traffic chain road is normal condition, and above-mentioned subsystem A is in addition to can be by above-mentioned target at this time
Business datum is returned to other than the first user by service customer end, can also be using above-mentioned target service data as successfully calling
Business datum, caching is to above-mentioned data temporary storage space.
It is subsequent, if second user is linked into above-mentioned service sub-system A by service customer end, rely on above-mentioned serial industry
Business link, when initiating to be directed to the data call of above-mentioned target service data again, if the downstream subsystem of service sub-system A is sent out
Raw failure causes subsystem C can not be by above-mentioned target service data back to above-mentioned subsystem A, and subsystem A can be from upper at this time
It states and reads the target service data in data temporary storage space, and the target service data read are returned to above-mentioned
Two users, to guarantee the stability of above-mentioned serial traffic link.
Certainly, after the first user initiates to be directed to the calling of above-mentioned target service data, if subsystem A confirmation does not receive
The target service data of subsystem C passback, can also read the target service data (i.e. from above-mentioned data temporary storage space
Before the first user successfully calls above-mentioned target service data, there are other users successfully to call and obtain prior to the first user
Get above-mentioned target service data), the target service data read are then returned into above-mentioned first user.
Wherein, it should be noted that above-mentioned subsystem A in the movement for returning to above-mentioned target service data to the first user,
Movement that above-mentioned target service data cache in above-mentioned data temporary storage space is executed into elder generation with above-mentioned subsystem A
Sequence afterwards, in the present specification without being particularly limited to.
In a kind of embodiment shown, above-mentioned subsystem A initiation faces above-mentioned target service data to above-mentioned data
When memory space cached after, may further determine that whether above-mentioned target service data cache success；If cached successfully,
Above-mentioned target service data are returned into first user by service customer end again.
In this way, it can be ensured that again successfully cache above-mentioned target service data empty to above-mentioned data temporary storage
Between after, then to above-mentioned first user above-mentioned target service data are returned to, so as to avoid due to above-mentioned target service data not
Being successfully accessed above-mentioned data temporary storage space can not obtain when caused same user calls identical business datum again
The problem of business datum, helps to promote user experience.
Certainly, in practical applications, above-mentioned subsystem A is in the movement for returning to above-mentioned target service data to the first user,
The movement for caching above-mentioned target service data in above-mentioned data temporary storage space with above-mentioned subsystem A, can also be with
It is performed simultaneously；Alternatively, above-mentioned subsystem A is in the movement for returning to above-mentioned target service data to the first user, it can also be prior to upper
Subsystem A is stated to execute the movement that above-mentioned target service data cache in above-mentioned data temporary storage space.
Continuing with referring to Fig. 3, it is assumed that second user relies on above-mentioned serial traffic link and initiated again for above-mentioned target
The calling of business datum, at this time when above-mentioned subsystem A receives the data call for target service data of second user initiation
It after request, can adopt in a like fashion, data call request is further issued to subsystem B, again should by subsystem B
Data call request continues to be issued to subsystem C.When above-mentioned subsystem C is calling relevant data service, relevant industry is accessed
It, can be further by the target service data to above-mentioned serial traffic after business database therefrom inquires above-mentioned target service data
The upstream subsystem of link is returned, which is further back to subsystem B, then by subsystem B
Further return to subsystem A.
And subsystem A, still it can be asked in the data call by the first Client-initiated for above-mentioned target service data
It asks after being further handed down to downstream subsystem, determines immediately whether and receive the mesh that subsystem C is returned by above-mentioned service link
Mark business datum.Wherein, specific validation testing repeats no more, the record before please referring to.
