Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the above technical problem, embodiments of the present invention provide a method, an apparatus and a system for acquiring streaming media resources, and first, the method for acquiring streaming media resources provided by embodiments of the present invention is described in detail below.
The method for acquiring streaming media resources provided by the embodiment of the present invention is applicable to a streaming media system, as shown in fig. 1, the streaming media system may include a terminal, a streaming media service device, and a platform, and certainly may include other parts, which are not limited herein.
The signaling interaction process among the terminal, the streaming media service device and the platform is shown in fig. 2:
the terminal sends a path acquisition request to the platform; and when the platform verifies that the terminal is legal, sending a first path and a first service bill corresponding to the path acquisition request to the terminal.
Specifically, verifying whether the terminal is legal may be understood as verifying whether the terminal has the right to acquire the first path. The platform can store the authority of each terminal in the streaming media system, wherein the authority is a path which can be acquired by each terminal. When the platform verifies that the terminal has the authority to acquire the path requested by the terminal (namely, when the verification terminal is legal), the first path requested by the terminal and the first service bill are sent to the terminal.
It should be noted that the Service Ticket (ST, Service Ticket) may be a Ticket used for verifying the identity of the user in CAS (central authentication Service, a single sign-on framework applicable to WEB), and the Service Ticket is valid only in a limited time period and cannot be reused.
After receiving the first path and the first service ticket, the terminal sends a resource acquisition request to the streaming media service equipment corresponding to the first path, wherein the resource acquisition request comprises the first service ticket.
The first path may include identification information of the streaming media service device, where the identification information may be information that can uniquely identify the streaming media service device, such as a serial number and an address of the streaming media device, and the terminal may determine the streaming media service device corresponding to the first path according to the identification information, where the streaming media service device is a device that can provide streaming media resources required by the terminal. And the terminal sends a resource acquisition request to the streaming media service equipment, wherein the resource acquisition request comprises the first service bill.
After receiving the resource acquisition request, the streaming media service equipment sends a second service bill to the platform; the platform validates the second ticket. It should be noted that, in a normal case, the first service ticket and the second service ticket are the same ticket, and if an abnormal condition, such as an intrusion by an illegal user, occurs, and the illegal user acquires a previously used service ticket, sends the used service ticket as the second service ticket to the platform, and tries to pass the verification of the platform, in this case, the second service ticket is different from the first service ticket, so that the platform verifies the second service ticket, that is, verifies whether the second service ticket is the same as the first service ticket, and if so, the verification passes.
The platform sends the verification result aiming at the second service ticket to the streaming media service equipment; and when the verification result shows that the verification is passed, the streaming media service equipment sends the streaming media resource corresponding to the resource acquisition request to the terminal.
And when the verification result shows that the verification is passed, the streaming media service equipment sends the streaming media resource requested by the terminal to the terminal, wherein the abnormal condition does not occur.
The service ticket in the scheme is effective only in a limited time period and can not be used repeatedly, even if an illegal user obtains the used service ticket, the streaming media resource can not be obtained from the streaming media service equipment, and the safety of obtaining the streaming media resource is improved.
Fig. 3 is a schematic flowchart of a method for acquiring streaming media resources applied to a platform according to an embodiment of the present invention, where the method includes:
s101: and receiving a path acquisition request sent by the first terminal.
In this embodiment, the platform is responsible for managing the streaming media system, as described above, the platform may store the rights of each terminal, where the rights are the paths that each terminal can obtain, and may also be understood as the corresponding relationship between the terminal and the streaming media service device; the path may be understood as a corresponding relationship between the streaming media service device and the streaming media resource, that is, information of which streaming media resource can be obtained from which streaming media service device by each terminal is stored in the platform. Therefore, when the first terminal needs to acquire the streaming media resource, it first requests the platform to acquire a path of the streaming media resource.
Assuming that the first terminal needs to acquire the streaming media resource a1, a path (first path) for acquiring a1 needs to be acquired first, and therefore, the first terminal sends a path acquisition request to the platform to request acquisition of the first path.
S102: and verifying the first terminal, and sending a first path and a first service bill corresponding to the path acquisition request to the first terminal when the first terminal is verified to be legal.
As an embodiment of the present invention, the step may include:
judging whether a first streaming media service device corresponding to the path acquisition request corresponds to the first terminal according to a corresponding relation between a terminal and streaming media service devices stored in the first streaming media service device, and if so, sending a first path corresponding to the path acquisition request to the first terminal;
judging whether the first terminal successfully logs in the streaming media system or not;
and if so, sending the first service ticket to the first terminal.
That is, the platform verifying whether the first terminal is legitimate includes two aspects:
in the first aspect, whether the first terminal has the authority to acquire the first path is verified. As described above, the platform stores the rights of each terminal in the streaming media system, and when the platform verifies that the first terminal does not have the right to acquire the first path, the platform may not perform processing, or may send a prompt message that the first terminal does not have the right to the first terminal, where the platform is not limited; and when the platform verifies that the terminal has the authority to acquire the first path, sending the first path and the first service bill to the terminal.
The permission of the first terminal is verified, so that the condition that the user obtains the streaming media resource without the right can be avoided.
The first path is the path for obtaining a1, and the first path may include identification information of the streaming media service device, where the identification information may be information that can uniquely identify the streaming media service device, such as a serial number and an address of the streaming media device. That is, a1 can be obtained from the streaming service device. Assume that the first path includes the identification information of the streaming media service device as a.
And in the second aspect, whether the first terminal successfully logs in the streaming media system is verified, and if so, the first service ticket is sent to the first terminal. As an embodiment of the present invention, after receiving a service ticket request sent by a first terminal, it may be determined whether the first terminal successfully logs in a streaming media system, and if so, the first terminal sends a first service ticket requested by the first terminal to the first terminal.
It should be noted that the Service Ticket (ST, Service Ticket) may be a Ticket used for verifying the identity of the user in CAS (central authentication Service, a single sign-on framework applicable to WEB), and the Service Ticket is valid only in a limited time period and cannot be reused.
In addition, in the CAS implementation, the platform can allocate a service Ticket to the terminal only when the TGC (Ticket writing Cookie, a Ticket indicating successful single sign-on in the CAS is placed in the Cookie of the user) is stored in the terminal, and the TGC is stored in the terminal only when the terminal successfully logs in the streaming media system. Therefore, only in the case that the first terminal successfully logs in the streaming media system, the platform can allocate the first service ticket to the first terminal and send the first service ticket to the first terminal.
S103: receiving a second service ticket sent by a first streaming media service device, wherein the first streaming media service device is a device corresponding to the first path, the second service ticket is sent by the first streaming media service device after receiving a resource acquisition request sent by the first terminal, and the resource acquisition request includes the first service ticket.
After receiving the first path and the first service ticket, the terminal may determine, according to the identification information a of the streaming media service device included in the first path, a first streaming media service device (i.e., a) corresponding to the first path, where the streaming media service device a is a device capable of providing streaming media resources required by the terminal.
The terminal sends a resource acquisition request to the streaming media service equipment A, wherein the resource acquisition request comprises a first service bill. And after receiving the resource acquisition request, the streaming media service equipment A sends a second service bill to the platform. It should be noted that, in a normal case, the first service ticket and the second service ticket are the same ticket, and if an abnormal condition, such as an intrusion by an illegal user, occurs and the illegal user obtains a previously used service ticket, the used service ticket is sent to the platform as the second service ticket, in this case, the second service ticket is different from the first service ticket.
S104: and verifying the second service ticket, and sending a verification result aiming at the second service ticket to the first streaming media service equipment so that the first streaming media service equipment sends the streaming media resource corresponding to the resource acquisition request to the first terminal when the verification result shows that the verification is passed.
As described above, the platform verifies the second service ticket, i.e. verifies whether the second service ticket is the same as the first service ticket, and if so, the verification is passed.
As an embodiment of the present invention, after the platform sends the first service ticket to the first terminal, the platform may record a corresponding relationship between the first terminal and the first service ticket. Validating the second service ticket may include: and judging whether the second service bill corresponds to the first terminal or not according to the recorded corresponding relation between the first terminal and the first service bill, and if so, indicating that the second service bill is verified to be passed.
Assuming that after the platform records the corresponding relationship between the terminal X and the service ticket X1, an illegal user invades the terminal X and tampers with the service ticket, the service ticket is changed into X2, and the terminal X sends the service ticket X2 to the platform, in this case, the platform judges that the terminal X does not correspond to the service ticket X2, that is, the second service ticket is not verified. In this case, the platform may not perform processing, or may send a prompt message indicating that the verification fails to be performed to the terminal X, which is not limited herein.
Under normal conditions, when no illegal user invades the terminal X, the terminal X sends the service bill X1 to the platform, and the platform judges that the terminal X corresponds to the service bill X1, that is, the second service bill is verified to be passed.
As an embodiment of the present invention, after receiving the second service ticket, the platform may call an API of the CAS to verify the second service ticket, and after the verification is successful, the platform returns the identification information of the terminal corresponding to the second service ticket, where the identification information may be information that can uniquely identify the terminal, such as a serial number and an address of the terminal. And judging whether the corresponding relation between the returned identification information of the terminal and the second service bill is consistent with the recorded corresponding relation, if so, indicating that the verification is passed.
In this embodiment, there are three possible verification results, the first one is that the verification passes, the second one is inconsistent, and the third one is that the service ticket is not verified.
The platform sends the verification result to the streaming media service device A, and when the verification result shows that the verification is passed, the streaming media service device A sends the streaming media resource A1 to the terminal. That is, in the case that the terminal is a valid user, the terminal finally acquires the streaming media resource required by itself through layer-by-layer verification.
With the embodiment of the present invention shown in fig. 3, a terminal sends a path acquisition request to a platform, the platform returns a path and a service ticket corresponding to the path acquisition request to the terminal when verifying that the terminal is legal, the terminal sends a resource acquisition request to a streaming media service device corresponding to the path, the resource acquisition request includes the service ticket, the streaming media service device sends the service ticket to the platform, the platform verifies the service ticket and sends a verification result to the streaming media service device, and when the verification result shows that the verification passes, the streaming media service device sends the streaming media resource corresponding to the resource acquisition request to the terminal. The service ticket in the scheme is effective only in a limited time period and can not be used repeatedly, even if an illegal user obtains the used service ticket, the streaming media resource can not be obtained from the streaming media service equipment, and the safety of obtaining the streaming media resource is improved.
Fig. 4 is a schematic flowchart of a method for acquiring streaming media resources applied to a terminal according to an embodiment of the present invention, where the method includes:
s201: and sending a path acquisition request to the platform.
In this embodiment, the platform is responsible for managing the streaming media system, as described above, the platform may store the rights of each terminal, where the rights are the paths that each terminal can obtain, and may also be understood as the corresponding relationship between the terminal and the streaming media service device; the path may be understood as a corresponding relationship between the streaming media service device and the streaming media resource, that is, information of which streaming media resource can be obtained from which streaming media service device by each terminal is stored in the platform. Therefore, when the first terminal needs to acquire the streaming media resource, it first requests the platform to acquire a path of the streaming media resource.
Assuming that the terminal needs to acquire the streaming media resource a1, a path (first path) for acquiring a1 needs to be acquired first, and therefore, the terminal sends a path acquisition request to the platform to request acquisition of the first path.
S202: and receiving a first path and a first service bill corresponding to the path acquisition request sent by the platform, wherein the first path and the first service bill are sent by the platform under the condition that the terminal is verified to be legal.
And after receiving the path acquisition request, the platform verifies the legality of the terminal. Specifically, the platform verifies whether the terminal is legal or not, and the platform includes two aspects:
in the first aspect, whether the terminal has the authority to acquire the first path is verified. The platform stores the authority of each terminal in the streaming media system (the corresponding relation between the terminal and the streaming media service device). When the platform verifies that the terminal does not have the authority to acquire the first path, the platform does not need to process the first path, and can also send prompt information without the authority to the terminal, wherein the prompt information is not limited; and when the platform verifies that the terminal has the authority to acquire the first path, sending the first path and the first service bill to the terminal.
The permission of the terminal is verified, so that the condition that the user obtains the streaming media resource without the right can be avoided.
The first path is the path for obtaining a1, and the first path may include identification information of the streaming media service device, where the identification information may be information that can uniquely identify the streaming media service device, such as a serial number and an address of the streaming media device. Assume that the first path includes the identification information of the streaming media service device as a.
And in the second aspect, whether the terminal successfully logs in the streaming media system is verified, and if so, the first service ticket is sent to the terminal. As an embodiment of the present invention, the terminal may send a service ticket request to the platform, and the platform determines whether the terminal successfully logs in the streaming media system after receiving the service ticket request sent by the terminal, and if so, sends the first service ticket requested by the terminal to the terminal.
It should be noted that the Service Ticket (ST, Service Ticket) may be a Ticket used for verifying the identity of the user in CAS (central authentication Service, a single sign-on framework applicable to WEB), and the Service Ticket is valid only in a limited time period and cannot be reused.
In addition, in the CAS implementation, the platform can allocate a service Ticket to the terminal only when the TGC (Ticket writing Cookie, a Ticket indicating successful single sign-on in the CAS is placed in the Cookie of the user) is stored in the terminal, and the TGC is stored in the terminal only when the terminal successfully logs in the streaming media system. Therefore, only in the case that the first terminal is successfully logged in the streaming media system, the platform can allocate the first service ticket to the first terminal and send the first service ticket to the first terminal.
S203: and sending a resource acquisition request to first streaming media service equipment corresponding to the first path, wherein the resource acquisition request comprises the first service bill.
After receiving the first path and the first service ticket, the terminal may determine, according to the identification information a of the streaming media service device included in the first path, a first streaming media service device (i.e., a) corresponding to the first path, where the streaming media service device a is a device capable of providing streaming media resources required by the terminal.
The terminal sends a resource acquisition request to the streaming media service equipment A, wherein the resource acquisition request comprises a first service bill. And after receiving the resource acquisition request, the streaming media service equipment A sends a second service bill to the platform. It should be noted that, in a normal case, the first service ticket and the second service ticket are the same ticket, and if an abnormal condition, such as an intrusion by an illegal user, occurs and the illegal user obtains a previously used service ticket, the used service ticket is sent to the platform as the second service ticket, in this case, the second service ticket is different from the first service ticket.
The platform verifies the second service ticket, namely verifies whether the second service ticket is the same as the first service ticket, and if so, the verification is passed.
S204: receiving a streaming media resource sent by the first streaming media service device, where the streaming media resource is sent by the first streaming media service device when a verification result for a second service ticket sent by the platform is received and the verification result shows that the verification passes, and the second service ticket is: and the first streaming media service equipment receives the resource acquisition request and then sends the resource acquisition request to the platform.
