- FIG. 5 is a schematic diagram showing the construction of a swf file header according to an embodiment of the present invention.
- Step 103 Publish the swf file in the format confusion through the Weibo platform.
- step 101 and step 102 After performing step 101 and step 102, that is, after the document file format conversion is successful and the swf file format is confused, the microblog platform can issue a background conversion success signal, and then update the temporary microblog data to the official data and write to the microblog database. Therefore, the swf file of the format confusion is formally uploaded through the microblog form, and the user is presented with an online preview reminder information.
- the method may further include: downloading the formatted swf file by the user through the microblog platform; and then using the flash player in the browser to inversely transform the swf file, and playing the reverse transformed swf file.
- the downloading the formatted swf file by the user through the microblog platform may include: requesting the public key to be distributed to the microblog platform; receiving the public key returned by the microblog platform; sending the private key and the returned public key to the microblog platform.
- the co-generated key after the microblog platform authenticates the key, receives the formatted conf file from the microblog platform.
- the reverse transformation work may include: removing the forged header; removing the random string according to the length of the random string; and XORing again to obtain the true header of the swf file.
- the flash player can process each swf file and play it.
- the microblog platform can perform the conversion on the fly, or can perform the conversion at regular intervals. After storing the microblog temporary data successfully, the microblogging platform can issue a format conversion request to the conversion background server, and convert the background server startup process to perform the instant conversion service.
- the conversion background server can also have a time conversion detection task, and convert the file that fails the instant conversion again to eliminate the unpredictable factors (such as request service timeout, network instability, code abnormality, etc.), which leads to the probability of real-time conversion failure.
- the status code of the document file can be set in advance. For example: When the status code of the document file is 2, it indicates that the format conversion has been successful; when the status code of the document file is 1, it indicates that the format conversion has not been performed; when the status code status of the document file is -1, the format conversion fails.
