It as shown in Figure 1 can portion for the HTTP business that flowing of access is larger for a kind of application scenarios of application scheme Multiple servers are affixed one's name to, and are shunted by load-balancing device.When the browser access HTTP business of user equipment, load is equal The access request message of browser will be distributed to some server disposed by weighing apparatus equipment according to default distributing strategy, to So that the flow of access HTTP business is more balancedly dispersed to the several servers disposed, individual server is avoided pressure occur Excessive situation.But for the access that browser needs to carry out in the same session, load-balancing device needs to be visited again Ask that request message is distributed to same server, it is normal to ensure to access.A kind of common session of load-balancing device is kept Mode keeps for HTTP cookie sessions, therefore, before load-balancing device comes into operation, to its HTTP cookie session It keeps function to be tested, is a pith of load-balancing device test, and the testing efficiency of this part is also by shadow Ring the testing efficiency of entire load-balancing device.
Therefore, in order to improve the efficiency that load-balancing device HTTP cookie sessions keep functional test, test is saved Manpower and time, the application provides a kind of load-balancing device session and keeps test method, shown in Figure 2, may include with Lower step:
S101, simulation browser access the responsible HTTP business of the load-balancing device;
S102 uses the HTTP in the case where receiving the HTTP cookie that opposite end server is sent to this equipment Cookie accesses the HTTP business with repeating preset times;
Whether S103, monitoring are normal to the access of the HTTP business;
S104 stops accessing the HTTP business, and record in the case where monitoring the access exception to the HTTP business It is abnormal to access result.
The purpose of the application is to test the browser of user equipment when accessing HTTP business, the HTTP of load-balancing device Whether cookie sessions keep function normal, i.e., whether browser can carry out certain continuous access in the same session.Cause This first can be with the behavior of simulation browser when the HTTP cookie sessions for testing any load-balancing device keep function Mechanism accesses the responsible HTTP business of the load-balancing device.For example, in general load-balancing device with can recording virtual IP address Location then can access the IP address recorded in the load-balancing device, or simulation in such a way that simulation browser accesses IP address The corresponding domain name of browser access is to the dereference IP address.It is understood that access process can also pass through other Specific implementation, as long as can realize that simulation browser accesses the purpose of HTTP business, the basic scheme reason of the application By being above not required to be defined concrete implementation mode, those skilled in the art can neatly select to close in practical application Suitable mode.
When user is by the browser access HTTP business of the equipment such as computer, mobile phone, in order to realize that session is kept, in user After browser accesses some HTTP business for the first time, if accessed normally, user browser will receive what opposite end server was sent HTTP cookie, and user browser after to the connected reference of the HTTP business during, if in access request message Including the HTTP cookie, load-balancing device sends HTTP before will being directly distributed to the access request message The server of cookie, without being distributed to other servers according to preset distributing strategy, to pass through HTTP Cookie realizes that the session between user browser and same server is kept.
Therefore in the embodiment of the present application, simulation browser accesses the responsible HTTP business of the load-balancing device for the first time When, load-balancing device will divide according to preset distributing strategy, the request message that the browser simulated is proposed when accessing It is dealt into some corresponding server of the HTTP business.If this equipment does not receive the HTTP that opposite end server is sent Cookie, it may be considered that the access exception of the HTTP business, in this case, in a kind of specific implementation mode of the application In, it can stop accessing the HTTP business, and record access result is abnormal, to complete to equipment HTTP cookie meetings Words keep the primary test of function, and test result is that equipment HTTP cookie sessions keep function abnormal.If this Equipment receives the HTTP cookie that opposite end server is sent, then can continue to execute the HTTP cookie meetings for testing the equipment Words keep the subsequent step of function, i.e. the HTTP cookie use principle of simulation browser, repeatedly to the load balancing Equipment transmission includes the access request message of the HTTP cookie received, and then accesses the HTTP business, and monitors State access it is whether normal, if it find that access exception, it may be considered that the HTTP cookie sessions of the equipment are keeping function not just Often, it can stop accessing the HTTP business and the case where access exception is recorded, tester is according to the record of test, i.e., It can further analyze and determine to obtain test result.
Wherein, before stopping access because access exception is monitored, the preset times of repeated accesses can be by tester Member is set according to actual demand, for example, browser can to the access of HTTP business in the same session under normal circumstances Can be for ten several times, then tester can set the repeated accesses HTTP business 20 times, but the basic scheme of the application is theoretically It is not required to be defined specific number, those skilled in the art can neatly set in practical application.
It, first, can when whether monitoring is normal to the access of the HTTP business in a kind of specific implementation mode of the application After this equipment simulating browser sends out access request message, to monitor whether to receive what opposite end server was sent to this equipment Response data message can be obtained further if receiving the response data message that opposite end server is sent to this equipment Conditional code therein, conditional code can indicate the respond style of opposite end server, generally 3 digit numerical codes, such as common Conditional code has:2xx indicates that request is successfully received;5xx indicates server mistake;Etc..Therefore conditional code is obtained later Judge whether the access to the HTTP business is normal.If, can according to conditional code judgement to the access exception of the HTTP business To stop accessing the HTTP business, and record access result is abnormal.Meanwhile it as described above, if not being received after accessing for the first time The HTTP cookie sent to opposite end server then also can determine that the access exception to the HTTP business, stop accessing the HTTP Business, and record access result is abnormal.It, can also be by specific conditional code, do not receive in addition, in record access exception Situations such as HTTP cookie, is specifically recorded, so that tester judges the concrete reason of access exception.Certainly, it monitors To the access of the HTTP business whether normally there is also other realization methods, the basic scheme of the application be theoretically not required to this into Row limit, those skilled in the art can by practical application, according to specific demand neatly select it is suitable in a manner of.
After S101 to S104 of execution, you can think to complete once to load-balancing device HTTP cookie Session keeps the test of function, and will obtain recorded access as a result, for further analyzing and determining test result.For Abundant simulation different user uses different browsers in different network environments, passes through the load-balancing device and accesses HTTP industry When business, whether the HTTP cookie sessions of the load-balancing device keep function normal, in a kind of specific embodiment party of the application In formula, the HTTP cookie that this equipment receives in S102 can also be removed, and execute S101 to S104 again.Due to removing HTTP cookie, then when simulation browser accesses the HTTP business, that is, access for the first time should for some browser HTTP business, its access request message will be distributed to some server, possibility will by load-balancing device according to distributing strategy Be from servers different before, therefore repeat S101 in multiple times to S104, you can to realize simulation different user not With different browsers are used in network environment, function is kept to test the HTTP cookie sessions of the load-balancing device.
As it can be seen that using application scheme, after simulation browser for the first time accesses HTTP business, if accessing normal, reception The HTTP cookie that opposite end server is sent have been arrived, automatically the repeated accesses HTTP business, monitoring can whether just to have been accessed Really, the situation for stopping accessing simultaneously record access exception in access exception, without tester's manually repetitive operation.This Outside, after completing primary test, it can also set and automatically begin to next test, and execute repeatedly test, to save manpower With the time, the efficiency that load-balancing device HTTP cookie sessions keep functional test is improved.
