In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
A video acquisition method and system according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
A first embodiment of the present invention provides a video acquisition method, including:
the method comprises the steps that a client player sends a URL obtaining instruction to a video website server, wherein the URL obtaining instruction comprises a target video identifier;
the client player acquires a first URL returned by the video website server in response to the URL acquisition instruction; wherein the first URL comprises a target URL corresponding to the target video identifier and a first random character string;

the client player sends the second URL to a video processing server through a proxy server;
and the video processing server returns the target video corresponding to the second URL to the client player through the proxy server.
The method of the embodiment of the invention can be applied to the application scenario shown in fig. 1. In this scenario, the terminal device 1 includes a terminal device 1, a video website server 2, a proxy server 3, and a video processing server 4, where the terminal device 1 may be a terminal device provided with a client player capable of playing a video, such as a notebook computer, a desktop computer, a mobile phone, and a tablet computer. A client player in the terminal device 1 may send a URL obtaining instruction to the video website server 2, where the URL obtaining instruction includes a target video identifier; the video website server 2 may return a first URL to the terminal device 1 in response to the URL obtaining instruction; wherein the first URL comprises a target URL corresponding to the target video identifier and a first random character string; the terminal device 1 may generate a second URL according to the first URL; the second URL comprises the target URL and a second random string; the terminal device 1 may send the second URL to the video processing server 4 through the proxy server 3, so that the video processing server 4 may return the target video corresponding to the second URL through the proxy server 3. It can be seen that, in this embodiment, the URL used for acquiring the target video includes the random character string, so that the URL sent by the client player to the video processing server by the client player through the proxy server is always changed, and the URL sent by the client player received by the proxy server each time is different, so that the proxy server cannot directly return the locally cached video to the client player, thereby ensuring that the URL sent by the client player each time reaches the video processing server, and the target video corresponding to the target URL is returned to the client player by the video processing server, ensuring that the target video received by the client player is not tampered by the proxy server, and improving the security of video transmission. In addition, the invention ensures low data processing overhead only by adding the random character string in the URL corresponding to the video without encrypting the video content, thereby improving the video transmission efficiency and reducing the video transmission cost on the premise of ensuring the video transmission safety.
It should be noted that the specific type, number, and combination of the terminal devices 1 may be adjusted according to the actual requirements of the application scenarios, which is not limited in this embodiment of the present invention.
It should be noted that the above application scenarios are only presented to facilitate understanding of the present invention, and the embodiments of the present invention are not limited in any way in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.
Fig. 2 is a signaling diagram of a video acquisition method according to an embodiment of the present invention. As shown in fig. 2, the video acquisition method includes:
s201: and the client player sends a URL acquisition instruction to the video website server.
In this embodiment, the URL obtaining instruction may include a target video identifier, where the target video identifier may be understood as an identifier of a video that needs to be played by the client player, for example, a number, a name, and the like of the video.
As an example, when a user needs to play a video online by using a client player, the client player may first obtain an identifier corresponding to the video, and use the identifier corresponding to the video as a target video identifier. And then, the client player generates a URL acquisition instruction corresponding to the video according to the target video identifier. Then, the client player may send a URL obtaining instruction to the video website server so as to obtain a URL (Uniform Resource Locator) corresponding to the video.
S202: and the client player acquires a first URL returned by the video website server in response to the URL acquisition instruction.
After the video website server obtains the URL obtaining instruction, the video website server may respond to the URL obtaining instruction, first obtain a target URL corresponding to a target video identifier in the URL obtaining instruction, and generate a first random character string. Then, the video website server may generate a first URL according to the target URL and the first random string, and return the first URL to the client player.
The first random string may be a query string (query string), and the first random string may also be a random number. It is understood that the video website server may add the first random string to the HTTP URL of the video file corresponding to the target video identifier published by the video website by adding an HTTP query string to the HTTP URL, or may add a random number to a specific location in the path of the URL (such as the last portion location of the URL, the middle portion location, the location between the host name and the file name).
For example, suppose the HTTP URL of the video file corresponding to the target video identifier published by the video website server on the video website is HTTP:// video.abc.com/m/123456. mp 4; if the first random string is a query string, the video website server may add an HTTP query string "random ═ 42524" to the HTTP URL to obtain a first URL, where the first URL is "HTTP:// video.abc.com/m/123456. mp4random ═ 42524"; if the first random string is a random number, the video website server may add a random number "42524" to a position between the host name and the file name in the path of the HTTP URL, resulting in a first URL, where the first URL is "HTTP:// video.
In an implementation manner, in order to improve security of data transmission, the first URL may be obtained by encrypting a target URL and a first random character string corresponding to the target video identifier. That is to say, the video website server may encrypt the target URL and the first random character string corresponding to the target video identifier to obtain the first URL.
As an example, the video website server may encrypt the target URL corresponding to the target video identifier and the field except the hostname (i.e., host name) in the first random string, where the encryption may be performed by using a symmetric encryption or an asymmetric encryption. Thus, the target URL is encrypted random string except that the hostname is unchanged. It should be noted that the video website server may irregularly replace the random character string in the first URL corresponding to the video content, re-encrypt the random character string, and then publish the random character string on the page of the video website. For example, assuming that the target URL and the first random string corresponding to the target video identifier are "http:// video.abc.com/m/123456. mp4random ═ 42524", after the video website server encrypts the target URL and the field except the hostname (i.e. the host name) in the first random string corresponding to the target video identifier, the first URL "http:// video.abc.com/ae 434htsdg567hfjdaf4fd 34" can be obtained, and as a result, the first URL is an encrypted random string except the hostname. In this way, the HTTP request received by the proxy server at a time can be made different, and thus the cache of the video by the proxy server is invalidated. It can be understood that, since the present embodiment does not encrypt the video content, only the URL needs to be encrypted, decrypted and transformed, the processing overhead is low, and no new device is introduced, thereby reducing the cost.
S203: the client player generates a second URL according to the first URL; the second URL comprises the target URL and a second random string;
after the client player receives the first URL, in order to further make the HTTP requests received by the proxy server different, a new URL may be formed, that is, the client player may generate a second URL according to the first URL, where the second URL includes the target URL and a second random string, and it needs to be noted that the first random string and the second random string are different. The second random string may be a query string (query string), and the second random string may also be a random number.
As an example, the client player may first obtain a target URL corresponding to the target video identifier according to the first URL; it is emphasized that, if the first URL is an encrypted URL, the client player may decrypt the first URL to obtain the target URL and the first random character string, and delete the first random character string to obtain the target URL.
The client player may then generate a second random string, and the client player may generate a second URL based on the second random string and the target URL. It should be noted that, in an implementation manner, in order to improve the security of data transmission, after the client player generates the second random character string, the client player may encrypt the second random character string and the target URL to generate the second URL. The client player may encrypt the target URL corresponding to the target video identifier and a field other than the hostname (i.e., host name) in the second random string, where the encryption may be performed by using a symmetric encryption or an asymmetric encryption.
That is, after obtaining the encrypted first URL from the video website server, the client player may decrypt the first URL, restore the original target URL, generate the second random string in the target URL according to the same rule again, and encrypt the second random string again to form the second URL, where the first URL is "http:// video. abc. com/ae434htsdg567hfjdaf4fd 34", and the updated second URL is "http:// video. abc. com/7hfjd9ae9214htsdg56af6dr439 f", for example.
Next, for example, suppose that the client player obtains an encrypted URL as "http:// video. abc. com/ae434htsdg567hfjdaf4fd 34" from the video website server, decrypts to obtain "http:// video. abc. com/m/123456.mp4random ═ 42524", and restores the original target URL, that is, "http:// video. abc. com/m/123456.mp 4", and then generates a second random character string "random ═ 32568" according to the same rule, so that a URL "http:// video. abc.abc.456/m/123456. mp4random ═ 568" generated according to the target URL and the second random character string can be obtained, and the URL "http:// video. abc. 929/hd/35. http:// h # 52" is encrypted by the client player 63568 ", and the URL is encrypted to form a second random character string, that is" http:// video. abc. 7 hfad 9/e.12.
S204: and the client player sends the second URL to the proxy server.
S205: and the proxy server sends the second URL to a video processing server.
After the client player generates the second URL, the client player may send the second URL to the proxy server, and the proxy server sends the second URL to the video processing server.
It should be noted that, in the process that the client player sends the second URL to the video processing server, the second URL sent by the client player is intercepted by the proxy server, and the proxy server may determine whether the same content (i.e., cache data) exists in the local cache of the proxy server according to the second URL. Since the path portion of the second URL includes a random character string (i.e., a second random character string), the proxy server cannot query the cache data corresponding to the second URL in the cache of the proxy server according to the second URL, and therefore, the proxy server may forward the HTTP request of the client player to the video processing server. That is, since the second URLs corresponding to the same target URL are always changed, the probability that the proxy server finds the cached video is greatly reduced, or even completely fails, and thus, each second URL finally reaches the server of the video website itself, that is, the video processing server.
S206: and the video processing server returns the target video corresponding to the second URL to the client player through the proxy server.
In this embodiment, the video processing server may first receive a second URL sent by the client player through the proxy server, and determine, according to the target URL in the second URL, a video corresponding to the target URL.
In this embodiment, after the video processing server obtains the second URL, the video processing server may determine a target URL in the second URL according to the second URL, and then the video processing server may determine a video corresponding to the target URL according to the target URL.
If the second URL is an encrypted URL, the video processing server may decrypt the second URL to obtain the target URL and the second random string; then, the video processing server may delete the second random character string to obtain the target URL; then, the video processing server may determine, according to the target URL, a video corresponding to the target URL.
For example, after receiving the second URL sent by the proxy server, the video processing server may decrypt the second URL "http:// video.abc.com/7 hfjd9ae9214htsdg56af6dr439 f", restore the original URL "http:// video.abc.com/m/123456. mp4random ═ 32568", delete the random number segment (i.e., the second random character string), obtain the target URL "http:// video.abc.com/m/123456. mp 4" corresponding to the video content, and then, the video processing server may determine the video corresponding to the target URL according to the target URL.
Then, the video processing server may generate a target video according to the video corresponding to the target URL and the inter-cut video corresponding to the video.
In one implementation, the video spots may be video segments, such as advertisements. As an example, after the video processing server obtains the target URL, a video corresponding to the target URL and an inter-cut video corresponding to the video may be determined according to the target URL; then, the video processing server may generate a target video according to the video corresponding to the target URL and the spot video corresponding to the video, for example, the video processing server may insert an advertisement into the video to obtain the target video.
The video processing server may then send the target video to the client player through the proxy server.
After the video processing server obtains the target video, the target video can be sent to the proxy server, so that the proxy server can send the target video to the client player. Therefore, after receiving the target video, the client player plays the target video for the user, and can play the inter-cut video, such as advertisement content, according to the set rule.
It should be noted that, after obtaining the target video, the proxy server may return the target video to the client server. Meanwhile, the proxy server can judge the on-demand popularity of the content in the recent period of time and decide whether to cache the video content locally. However, since the URLs in each HTTP request of the same video content are different, in general, the proxy server determines that the video content does not need to be cached, and even if the video content is cached, the next HTTP request of the same video content is received, and the cached video cannot be hit due to the different URLs, that is, the cached video of the same URL cannot be searched.
It should be noted that the client player, the proxy server and the video processing server may use the same key, and use a symmetric encryption algorithm to encrypt and decrypt the URL; the key can be replaced regularly and synchronized among the three; of course, an asymmetric encryption algorithm can be used, the proxy server and the video processing server use the same private key, the client player uses a public key before playing, the private key is periodically changed, and the three are synchronized.
All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
The following are embodiments of systems of the present invention that may be used to perform embodiments of methods of the present invention.
