Step S102, comparing the received estimated consumption time with a preset response time threshold, and when the estimated consumption time is greater than the response time threshold, exporting the task to be downloaded to a task bar, wherein a task list is configured in the task bar;
in this embodiment, a response time threshold is preset, and by comparing the expected consumption time of the background database for generating the file stream with the response time threshold, it is determined whether the response time of the http interface is longer in the downloading task, and usually most of the time for downloading and exporting the file does not exceed 10 seconds, it should be noted that, in this embodiment, the response time threshold is set to 60 seconds, and if the response time exceeds 60 seconds, the response time is longer, so as to export the relevant task to be downloaded to the task bar, it can be understood that, in this embodiment, when the expected consumption time is less than or equal to the response time threshold, the background database generates the file stream and returns the generated file stream to the foreground through the http interface, and processes the file stream through blob, and finishing the task downloading.
Step S103, determining the task state of the task to be downloaded in the task list according to the file stream generation condition; and when the task state is the finished state, downloading the corresponding task to be downloaded.
After the task to be downloaded whose expected consumption time is greater than the response time threshold is exported to the taskbar, the task list configured in the taskbar still needs to be updated to show the task to be downloaded exported to the taskbar in the task list, it can be understood that a user determines whether to download the task to be downloaded by observing the task state of the task to be downloaded in the task list, where the task state of the task to be downloaded is determined according to the state of generating a corresponding file stream by the background database, and it needs to be noted that, in this embodiment, the task state of the task to be downloaded in the task list is updated in real time in a polling manner.
