The current method for setting the timeout time is to directly set in the configuration file of the application, or to set in the configuration center in a configuration centralization manner, and then dynamically pull by each application.
Both of the two methods have some defects, and for the method of setting the timeout time by using the configuration file, when the interface performance changes, the new timeout time needs to be manually estimated and the configuration file needs to be modified, and the new configuration file needs to be restarted to take effect when the new configuration file takes effect.

Therefore, the problem that when the timeout time of the calling interface is manually modified, the timeout time in the configuration file can only take effect by restarting the related application, and when the timeout time is pulled by using the configuration center, the timeout time cannot be modified in the configuration center in time due to the fact that the performance of the interface is found to be changed later manually, so that the system is dragged and crashed due to abnormal interface calling, or the interface cannot be called cannot be solved in the prior art.

The application provides a method for adjusting interface calling timeout, which comprises the following steps:
step S101: acquiring a first timeout time of an interface;
step S102: operating the interface within a first time range based on the first timeout;
step S103: acquiring calling data of the interface in a first time length range, wherein the calling data comprises overtime retry times caused by overtime, overtime failure times caused by overtime and calling time consumption;
step S104: judging whether the sum of the overtime retry times and the overtime failure times is larger than a first threshold value;
step S105: if the first timeout time is greater than the first threshold, increasing a first timeout time; if not, the first timeout time is reduced.
The present application is described in further detail below with reference to fig. 1.
Step S101: a first timeout of an interface is obtained.
And acquiring a first timeout time of the interface, wherein the first timeout time comprises the longest time from the beginning of calling the interface to the receipt of the feedback information, and the call beyond the first timeout time can be judged to be failed or start to retry. The initial first timeout period may be set by the user and may be adjusted thereafter according to the methods described herein.
Step S102: operating the interface within a first time range based on the first timeout;
the interface is operated in a first timeout range, the first timeout range can be a specific time length, the time length can be preset by a user, the interface can be operated by calling the interface for many times, so that the called working condition of the interface can be observed, stable working condition data can be obtained, and the working condition of the interface can be the timeout condition for discriminating the calling work of the interface according to the first timeout time.
Step S103: and acquiring the calling data of the interface in the first time length range, wherein the calling data comprises the times of timeout retry caused by timeout, the times of timeout failure caused by timeout and the calling time consumption.
The obtained call data can be call data formed by the working condition of the interface in the first time range, and the call data can record the times of retries and failures of the interface caused by exceeding the first timeout time in a plurality of calls in the first time range and the time consumed for calling the interface each time.
Step S104: and judging whether the sum of the timeout retry number and the timeout failure number is larger than a first threshold value.
And after adding the overtime retry times and the overtime failure times in the calling data, judging whether the value is larger than a first threshold value. The first threshold may be preset by a user, and is used for evaluating whether the call time of the interface needs to be reduced or increased, and when the interface performance is good, the call time is shorter, and when the interface performance is reduced, the call time is longer.
Step S105: if the first timeout time is greater than the first threshold, increasing a first timeout time; if not, the first timeout time is reduced.
When the sum of the retry times and the failure times of the interface is greater than a first threshold, it indicates that the performance of the interface is reduced, and the length of the first timeout time needs to be increased, and if the sum is less than the first threshold, it indicates that the performance of the interface is better, and the first timeout time of the interface can be reduced, so that more resources can be released as soon as possible.
In some embodiments of the present application, increasing the first timeout time may be increasing the first timeout time by 200 milliseconds.
When the first timeout is required to be increased, the system may directly increase the first timeout time by 200 ms without manual operation, and the increased value may be preset by the user according to practical situations, for example, directly increase by 300 ms or 100 ms, etc.
In other embodiments of the present application, the reducing the first timeout period may be reducing the first timeout period according to a time consumed by the call in the call data.
When the interface performance is good and the sum of the retry number and the failure number is smaller than the first threshold, the first timeout time should be reduced, and at this time, the first timeout time may be reduced according to the call time consumption in the call data.
In other embodiments of the present application, the first timeout time is reduced according to the call elapsed time in the call data, which may be calculating a first expected value of the call elapsed time and a first standard deviation of the call elapsed time by using normal distribution according to the call elapsed time in the call data, and reducing the first timeout time according to the first expected value of the call elapsed time and the first standard deviation of the call elapsed time.
The first timeout time is reduced according to the call time consumption in the call data, which may be calculating the call time consumption of each call of the interface running in the first time length range by normal distribution to obtain a first expected value, calculating a first standard deviation between each time consumption and the first expected value, the first expected value represents the average elapsed time that this interface is invoked over a first range of time lengths, and the first standard deviation represents the average deviation degree of each time consumption from the average time consumption, so as to obtain a reasonable fluctuation range close to the first expected value, for example, if it takes 300 milliseconds, 400 milliseconds, 100 milliseconds, 800 milliseconds, 500 milliseconds, 600 milliseconds, 900 milliseconds, 700 milliseconds, 200 milliseconds, 800 milliseconds to acquire 10 calls in the first time length range, the average time taken is 530 milliseconds, the standard deviation is 275.08 milliseconds, the meaning is that the interface call takes a reasonable range of time from 254.92 milliseconds to 805.08 milliseconds. And then the duration of the first timeout time is reduced according to the calculated first expected value and the first standard deviation.
In other embodiments of the present application, the first timeout time is reduced according to a first expected value of the call elapsed time and a first standard deviation of the call elapsed time, where the first expected value and/or the first standard deviation may be compared with a second expected value and/or a second standard deviation, respectively, where the second expected value is an expected value obtained by calculation based on the call elapsed time in the call data obtained when the interface call timeout time is adjusted last time, and the second standard deviation is a standard deviation obtained by calculation based on the call elapsed time in the call data obtained when the interface call timeout time is adjusted last time; and if the first expected value is smaller than a second expected value and/or the first standard deviation is smaller than a second standard deviation, reducing the first timeout time according to the first expected value of the call consumed time and the first standard deviation of the call consumed time.
In reducing the first timeout period according to the first expected value and the first standard deviation, the first expected value and the first standard deviation in the first duration range may be compared with an expected value and a standard deviation according to the previous adjustment, the previous adjustment may be an adjustment performed manually, or may be an adjustment performed according to a second expected value and a second standard deviation calculated in the first duration range last time, the second expected value includes an expected value calculated from the call elapsed time in the call data acquired when the first timeout period was adjusted last time, the second standard deviation includes a standard deviation calculated from the call elapsed time in the call data acquired when the first timeout period of the interface was adjusted last time, and when the second expected value and the second standard deviation are taken as a basis for adjusting the first timeout period last time, the first expected value and the first standard deviation calculated in the first duration range this time are compared with each other, when the first expected value is less than the second expected value and/or the first standard deviation is less than the second standard deviation, then the first timeout time is decreased.
In other embodiments of the present application, the first timeout time is reduced according to the first expected value of the call elapsed time and the first standard deviation of the call elapsed time, which may be obtained by adding the first expected value of the call elapsed time and N times of the first standard deviation of the call elapsed time, where N is a positive integer; and setting the timeout adjusting value as a first timeout.
When the first timeout time is decreased according to the first expected value of the call elapsed time and the first standard deviation of the call elapsed time, the first expected value may be added to N times of the first standard deviation of the call elapsed time, and the value is used as a timeout time adjustment value, where N may be any positive integer, for example, the first expected value is 530 milliseconds, the standard deviation is 275.08 milliseconds, and N is set to 1, the timeout time adjustment value is 805.08 milliseconds, and then the first timeout time is set to 805.08 milliseconds.
In other embodiments of the present application, the first expected value of the call elapsed time is added to the first standard deviation of the call elapsed time N times to obtain the timeout adjustment value, where the first expected value of the call elapsed time is added to the first standard deviation of the call elapsed time 2 times to obtain the timeout adjustment value.
When the timeout adjustment value is obtained by adding the first expected value of the call elapsed time to N times the first standard deviation of the call elapsed time, N may be set to 2, for example, the first expected value is 530 milliseconds, N is 2, the standard deviation is 275.08 milliseconds, and the timeout adjustment value is 1080.16 milliseconds.
In some embodiments of the present application, setting the timeout period adjustment value to a first timeout period may be comparing the timeout period adjustment value with the first timeout period; and if the timeout time adjustment value is smaller than the first timeout time, setting the timeout time adjustment value as the first timeout time.
After the adjustment value of the timeout time is calculated and obtained, the adjustment value of the timeout time may be compared with the first timeout time, and if the adjustment value of the timeout time is smaller than the first timeout time, the adjustment value of the timeout time is used as a new first timeout time. The scheme is to prevent the situation that the calculated timeout period adjustment value is greater than or equal to the first timeout period, and when the calculated timeout period adjustment value is greater than or equal to the first timeout period, the first timeout period cannot be reduced according to the timeout period adjustment value, for example, when N is an infinite value, the timeout period adjustment value is always greater than or equal to the first timeout period. Therefore, the first timeout time does not need to be adjusted when the timeout time adjustment value is greater than or equal to the first timeout time.
Fig. 2 is a schematic diagram of one embodiment of the method of the present application, which is described in further detail below with reference to fig. 2.
Step S201: a first timeout is obtained at a configuration center. The first timeout is stored in the configuration center so that it can be retrieved from this configuration center when the interface needs to be called.
Step S202: the interface is operated for a first time period. While the interface is running, relevant data of the interface operation can be collected or recorded, including calling data.
Step S203: and acquiring the overtime retry times, overtime failure times and calling time consumption in the calling data. The obtained calling data may not only include three types of data, i.e., the number of times of retry of the timeout, the number of times of failure of the timeout, and the time consumed for calling, but also may be acquired according to the user's requirement or use condition, for example, the number of times of success of the calling, the time of calling the interface, and the like.
Step S204: and judging whether the sum of the timeout retry number and the timeout failure number is larger than a first threshold value.
Step S205: if so, the first timeout time is increased by 200 milliseconds. And then, replacing the first timeout time of the original configuration center with the updated first timeout time.
Step S206: and if not, calculating a first expected value and a first standard deviation according to the acquired calling time consumption.
Step S207: and judging whether the first expected value and the first standard deviation are smaller than the second expected value and the second standard deviation at the same time.
Step S208: if yes, the sum of the first expected value and 2 times of the first standard deviation is used as the timeout adjusting value.
Step S209: the timeout time adjustment value is taken as the new first timeout time. And then replacing the first timeout time of the original configuration center with the updated first timeout time.
