After the terminal stores the data ID, the file to be downloaded is identified after receiving the download notification of the server according to the data ID, whether the file is the file to be downloaded is checked, if the file is the file to be downloaded, the downloading work is carried out, if the file is not the file to be downloaded, the terminal can end the transmission flow of the file, the terminal feeds the data ID of the file back to the server, the server modifies the state of the stored data of the file according to the data ID of the file, and notifies the user to cancel the uploading of the file according to the state of the stored data.
And 106, the user side sends each file in the file catalog and the corresponding data ID to the server side, the server side stores each file in the file catalog in the server side according to the data ID and records the stored data to the database, and the state of the stored data is changed from to-be-uploaded to downloading after the uploading is completed.
The file is stored in the server and the stored data is recorded in the database, the stored data, the data ID and the mark are in one-to-one correspondence identification relationship, and are not dependent relationships, the server modifies the state of the stored data in the database according to the data ID, obtains the state of the file according to the state of the modified stored data, and simultaneously sends related requests to the terminal and the user side for data transmission.
And step 108, when the server judges that the state of the stored data is downloading, the server informs the terminal of downloading the file, and after the terminal finishes downloading, the server feeds back the corresponding data ID to the server, and the server modifies the state of the stored data from downloading to finishing downloading according to the fed-back data ID.
And the server modifies the state of the stored data corresponding to the data ID in the database into the downloading completion according to the fed-back data ID. And carrying out accurate operation on the stored data in the database through the data ID.
The method, the system, the computer equipment and the storage medium for transmitting the data with multiple ends in series, wherein the user side sends a file uploading request to the server side, and the server side receives the file uploading request and feeds back the data ID of the file catalogue to be uploaded to the user side; the method comprises the steps that storage data of each file in a file directory are created in a database of a server side, the state of the storage data is marked to be uploaded, and the storage data, data IDs and marks correspond to each other one by one; the server side sends the data ID corresponding to the file directory to the terminal, and when the terminal receives the data ID, the terminal jumps to a page waiting for uploading and stores the data ID; the method comprises the steps that a user side sends each file in a file catalog and a corresponding data ID (identity) to a server side, the server side stores each file in the file catalog in the server side according to the data ID, the stored data are recorded in a database, and after uploading is finished, the state of the stored data is changed from uploading to downloading; when the server judges that the state of the stored data is downloading, the server informs the terminal to download the file, after the terminal finishes downloading, the corresponding data ID is fed back to the server, and the server modifies the state of the stored data from downloading to downloading according to the fed-back data ID.
In one embodiment, the method further comprises: when the terminal is in a state waiting for uploading, receiving a flow ending instruction, and forwarding a cancel downloading instruction to the user side through the server side according to the flow ending instruction and the data ID stored in the terminal so as to enable the user side to stop uploading files corresponding to the data ID.
The existing intelligent Yin Yun screen product is currently composed of three different modules, namely a user end, a terminal and a server end, wherein the user end and the terminal are not in physical communication, a user clicks a cancel file to upload at the terminal, and after receiving a flow end instruction, the terminal accurately informs the server end of a file to be cancelled according to the data ID of the file and exits from a page waiting to be downloaded. After receiving the instruction of canceling downloading, the server informs the user end to stop uploading the file corresponding to the data ID, and through the data ID, accurate communication between the terminal and the user end can be realized.
In one embodiment, according to the flow end instruction and the data ID stored in the terminal, modifying the state of the corresponding stored data in the database of the server from the state to be uploaded to the flow end state; when the user side uploads the file, if the state corresponding to the stored data of the file is detected to be the flow end state, the uploading of the file corresponding to the data ID is stopped.
When the user side uploads the file, the state corresponding to the stored data of the file is detected to be a flow end state and is not to be uploaded, and the user side stops uploading the file corresponding to the data ID.
In one embodiment, a client sends a file upload request to a server, and the server receives the file upload request and feeds back a data ID of a file directory to be uploaded to the client, including: each file in the file directory to be uploaded sends a file uploading request to the server, and the server creates a data ID corresponding to the file in the database after receiving the file uploading request.
The data IDs of the files are in one-to-one correspondence with the files, and the data IDs corresponding to the files created in the database are unique.
In one embodiment, after the server modifies the state of the stored data from being downloaded to being downloaded according to the fed-back data ID, the method further includes: when the preset deleting condition is met, modifying the state of the downloaded stored data into a flow ending state; the server traverses the database, and when a storage path exists in the storage data with the state of the flow end state, the server deletes the storage file corresponding to the storage path.
When the data volume of the database is too large, the load of the server becomes large, the running speed of the server becomes slow along with the increase, in order to prevent the data volume of the database from being too large, deletion conditions are preset according to the memory of the server and the data volume of the database, when the downloaded stored data accords with the deletion conditions, the state of the stored data with the state being the downloaded stored data is modified to be the flow end state according to the data ID fed back by the server, after the server traverses the database, the stored data with the state being the flow end state is deleted, the data volume of the database is reduced, and meanwhile, the stored files corresponding to the stored path are deleted.
In one embodiment, when the server side determines that the state of the stored data is downloading, notifying the terminal to download the file, including; when the server side judges that the state of the stored data is downloading, the server side informs the terminal of downloading the file, and after the terminal receives the notification, the terminal jumps to the file downloading page from the page waiting to be uploaded, and starts downloading the file.
After the file is uploaded at the server, judging that the file is in a downloading state according to the data ID, informing the terminal to download the file, after the terminal receives the notification, jumping from a page waiting for uploading to a file downloading page, starting downloading the file in the downloading page, monitoring the downloading progress, and after the file downloading is completed, exiting the file from the downloading channel.
