It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Referring to fig. 1 and 2, a file sharing method according to the present invention includes:
s1: uploading and storing the file to a server;
s2: the server generates a sharing link of the file and sends the sharing link to a pre-acquired target mailbox;
s3: after the sharing link is determined to be clicked and the server side authenticates, sending an extraction code to the target mailbox;
s4: and extracting the file of the server side through the extraction code and the sharing link.
It should be noted that the target mailbox is obtained in advance, and can also be stored in the server in advance.
In step S1, the user uploads and stores the file to the server in advance, where the file includes: documents, application packages, photos, videos, and so forth.
In step S2, the generated sharing link is sent to the target mailbox in the form of mail.
In step S3, the extraction code is equivalent to the password for obtaining the file in the server, and the file in the server can be extracted only by inputting the correct extraction code in the sharing link.
According to the method, firstly, according to a file prestored in a server, the server generates a sharing link of the file and sends the sharing link to a target mailbox; then, the target mailbox clicks the sharing link, and after the authentication of the server is successful, the server sends the extraction code to the target mailbox; and finally, extracting the file by the target mailbox through the sharing link and the extraction code. The invention realizes convenient file sharing, and greatly enhances the security of the file by acquiring the extraction code through the mailbox for extraction. Moreover, the method and the device are particularly suitable for sharing large files, greatly improve the convenience of file sharing, and simultaneously ensure the safety of the files.
Preferably, the sharing link includes: file address and expiration time.
It should be noted that the file address indicates a unique address where each file is stored in the server. The expiration time can be set according to requirements, for example, to a certain day of a certain month of a certain year or to a validity period of 7 days, etc. When the time exceeds the expiration time of the sharing link, the sharing link is automatically disabled.
Step S3, after determining that the sharing link is clicked and the server side authenticates, sending an extraction code to the target mailbox, including:
after the sharing link is clicked, sending feedback information to the server;
the server compares the time of the feedback information with the expiration time;
and the server matches the address of the feedback information with the address of the target mailbox.
Further, the comparing, by the server, the time of the feedback information with the expiration time includes:
if the time of the feedback information does not exceed the expiration time, the server side judges that the sharing link is in an effective state;
and if the time of the feedback information exceeds the expiration time, the server side judges that the sharing link is in an invalid state.
Further, the matching, by the server, the address of the feedback information with the address of the target mailbox includes:
if the address of the feedback information is consistent with the address of the target mailbox, the server side sends an extraction code to the target mailbox;
and if the address of the feedback information is inconsistent with the address of the target mailbox, the server side sends alarm information to the target mailbox.
It should be noted that after the sharing link is clicked, feedback information is sent to the server. Comparing the time of the feedback information with the expiration time of the sharing link, and if the expiration time is earlier than the time of the feedback information, judging that the sharing link is in an invalid state by the server side, namely the sharing link is invalid, and the user access request fails; if the expiration time is later than the time of the feedback information, the server side judges that the sharing link is in an effective state, namely the sharing link is effective, and the user can normally acquire the file resource through the sharing link.
Matching the address of the feedback information with the address of the target mailbox, and if the address of the feedback information is consistent with the address of the target mailbox, and the server side considers that the user of the target mailbox acquires the file, sending an extraction code to the target mailbox; if the address of the feedback information is inconsistent with the address of the target mailbox, the server considers that the user of the non-target mailbox acquires the file, namely the file is accessed by an illegal user, and the server sends alarm information to the target mailbox to prompt the user of the target mailbox. For example, when the user of the target mailbox shares the sharing link with other people for use, the other people click the sharing link and then send feedback information to the server, and the server recognizes that the address of the feedback information is not sent by the target mailbox address.
If the access is illegal, the server side can directly change the effective state of the sharing link into an invalid state and resend the effective sharing link to the target mailbox.
Step S4, extracting the file of the server through the extraction code and the sharing link, including:
inputting the extraction code in the sharing link to acquire the file address;
and extracting the file of the server side through the file address.
In step S4, the target mailbox receives the mail of the sharing link, and the user clicks the sharing link, inputs the extraction code, and obtains the file address. According to the file address, the user can obtain a complete file access path and perform downloading, previewing and other operations.
Preferably, the present invention further comprises:
and the server generates the sharing link by using a random function.
The random function has randomness, the security of the sharing link is guaranteed, and the file of the server side is not easy to illegally obtain by cracking the sharing link.
Preferably, the server of the present invention includes:
the cloud monitoring service is used for mastering the running condition of the stored file in real time, monitoring the CPU utilization rate of the cloud host and the CPU utilization rate of the physical machine in real time, and receiving and processing alarm information in time when an alarm occurs;
the object storage service is used for supporting the storage of files of various types;
and the encrypted storage service is used for carrying out encrypted storage and decrypted extraction on the file.
Preferably, the server includes: a cloud platform and/or a backend server.
The invention discloses a file sharing system, which comprises:
the uploading module 1 is used for uploading and storing the file to a server;
the processing module 2 is used for the server side to generate a sharing link of the file and send the sharing link to a pre-acquired target mailbox; after the sharing link is determined to be clicked and the server side authenticates the sharing link, sending an extraction code to the target mailbox;
