Background
With the continuous development of the mobile internet, in the face of the current situation that some super mobile applications (which are basic applications like "installation is necessary") occupy the main traffic entrance, many small and medium-sized applications begin to transform towards the form of light-like applications (or small programs).
Light Application like technology (Lite Application) is similar to Web applications, all of which have a host environment. The hosted environment of a light-like application is typically some super application (e.g., weChat, hundredth, etc.) as compared to the hosted environment of a Web application being a browser.

Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the present methods for running third party code in a sandbox environment or an apparatus for running third party code in a sandbox environment may be applied.
As shown in fig. 1, the system architecture 100 may include a first server 101, a network 102, and a second server 103. First server 101 is physically isolated from second server 103 (e.g., first server 101 and second server 103 are each located on different computing devices). The network 102 serves as a medium for providing a communication link between the first server 101 and the second server 103. Network 102 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The first server 101 may be a server that provides various services, such as a server for providing a sandbox environment. Third party code provided by the non-hosted environment may run in a sandbox environment. The sandbox environment may be configured with virtual interfaces that are invoked in the same manner as the real interfaces in the host environment. The first server 101 may detect a call to the virtual interface by the third party code. When the first server 101 detects that the third party code calls the virtual interface, it may send a request for calling a real interface corresponding to the virtual interface to the second server 103, and receive a result returned by the second server 103.
The second server 103 may also be a server that provides various services, such as a server for providing a hosting environment. The second server 103 may analyze and process data such as the call request sent by the first server 101 (e.g., determine a corresponding real interface, call the real interface to obtain a call result), and return a processing result (e.g., the call result) to the first server 101.
It should be noted that the method for running the third party code in the sandbox environment provided in the embodiment of the present application may be executed by the first server 101, and may also be executed by the second server 103. Accordingly, the means for running the third party code in the sandbox environment may be located in the first server 101 or in the second server 103. .
It should be noted that the first server 101 and the second server 103 may be hardware or software. When the first server 101 and the second server 103 are hardware, they may be implemented as a distributed server cluster composed of a plurality of servers, or may be implemented as a single server. When the first server 101 and the second server 103 are software, they may be implemented as a plurality of software or software modules (for example, to provide distributed services), or may be implemented as a single software or software module. And is not particularly limited herein.
It should be understood that the number of first servers, networks, and second servers in fig. 1 is merely illustrative. There may be any suitable number of first servers, networks, and second servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for running third party code in a sandbox environment in accordance with the present application is shown. The method for running third party code in a sandbox environment may include the steps of:
In this embodiment, the sandboxed environment may be deployed on a first server (e.g., first server 101 of fig. 1) and the hosted environment may be deployed on a second server (e.g., second server 103 of fig. 1). An executing agent (e.g., the first server 101 of fig. 1) of the method for running third party code in a sandbox environment may detect whether the third party code calls a virtual interface of an isolated operation type in the sandbox environment at runtime, and obtain an identification of the virtual interface when detecting that the third party code calls the virtual interface. Here, the third party code may be code provided by a non-hosted environment (e.g., a light-like application).
Here, the first server is physically isolated from the second server. For example, when a physical host is virtualized into multiple virtual hosts by using virtualization technology, the first server and the second server may be located on different physical hosts, so that physical isolation may be achieved, and further, the influence of third party code on the host environment is avoided.
Sandbox (Sandbox), also known as Sandbox or sand table, refers to a virtual technology in the field of computers. The basic principle is as follows: a virtual running environment is created according to the real running environment of a computer program, when a certain program tries to play a role, the program can be firstly run in a sandbox, and all changes caused by the program in the sandbox cannot cause any influence on the real running environment. Sandboxing is often used in the field of computer security, for example, to study computer virus characteristics using sandboxes, or to provide a test operating environment for programs that are not trusted by some sources, are destructive or cannot determine their intention, etc.
In this embodiment, the sandbox environment may be a restricted secure operating environment for providing an operating environment for third party code. The sandboxed environment may enable simulation of the host environment. In particular, the sandboxed environment may be configured with virtual interfaces of the isolated operation type, each of which may correspond to one of the target interfaces of the host environment, e.g., each of which may have the same identification as one of the target interfaces. The target interface corresponding to the virtual interface may be an interface capable of affecting the host environment.
In some optional implementations of this embodiment, the virtual interface and the corresponding target interface have the same calling mode. For example, the virtual interface and the corresponding target interface have the same call path, call parameter, and the like, but do not have the function of the target interface. The role of the virtual interface is to let the third party code think that it really called the target interface. Generally, since the third-party code does not sense whether the third-party code runs in the host environment or the sandbox environment, the third-party code calls the target interface in the host environment, and actually calls the virtual interface in the sandbox environment, so that the potential safety hazard brought to the host environment by the third-party code is avoided.
In some optional implementations of this embodiment, the method for running third party code in a sandbox environment may further include: and acquiring a calling parameter of the virtual interface in response to detecting that the third-party code calls the virtual interface of the isolation operation type in the sandbox environment at the running time. The implementation may be applicable to virtual interfaces that need to pass parameters.
In this embodiment, the execution subject may send a call request to the second server, so that the second server determines the target interface corresponding to the identifier obtained in step 201 in the hosting environment, and calls the target interface.
And step 203, receiving a calling result obtained after the target interface corresponding to the identifier returned by the second server is called.
In this embodiment, the execution subject may receive a call result obtained after the target interface corresponding to the identifier returned by the second server is called (and return the received call result to the third party code, thereby completing the interface calling process of the third party code).
Compared with the method for directly running the third party code in the host environment, the method for running the third party code in the sandbox environment provided by the embodiment can effectively isolate the running environment of the third party code from the host environment, so that the host environment can be prevented from being influenced when the third party code calls the interface.
In addition, in the related art, the security of the third party code is ensured by performing qualification auditing on the developers (for example, adding enterprises with strong public trust into a white list), but even the code submitted by the developers in the white list cannot avoid the existence of a bug, so that the host environment is influenced. In the application, even if the third-party code has a vulnerability, the method for running the third-party code in the sandbox environment provided by the embodiment can also avoid potential safety hazards brought to the host environment by the third-party code.
In addition, compared with the third party code submitted by a manual review developer, the method for running the third party code in the sandbox environment provided by the embodiment can reduce the labor cost of code review and accelerate the online progress of the third party code.
In some optional implementations of this embodiment, the method for running third party code in a sandbox environment may further include: and in response to not receiving the calling result within the preset time period, re-sending the calling request to the second server.
When the third party code calls the virtual interface, the first server deploying the sandbox environment communicates with the second server deploying the host environment once. To ensure that the communication is successful, a retry mechanism may be set at each communication. In this implementation, each successful communication can be ensured by setting a timeout (i.e., a preset time period) for retransmission.
Optionally, different timeout times may be set for different interfaces, so that it is possible to avoid that a third-party developer sets an error for an interface return time to send a call request multiple times.
In some optional implementations of this embodiment, the method for running third party code in a sandbox environment may further include: and in response to detecting that the third party code calls the target interface of the non-isolated operation type in the sandbox environment at runtime, directly calling the target interface of the non-isolated operation type. Here, the target interface of the non-isolated operation type may refer to an interface that confirms that it does not affect the host environment. As an example, the target interface of the non-isolated operation type may be an interface that obtains the current system time. By directly calling the target interface of the non-isolated operation type, the communication time between the sandbox environment and the host environment is reduced on one hand, and the request pressure of the second server is also reduced on the other hand.
In some optional implementations of this embodiment, before detecting the third party code, the method for running the third party code in the sandbox environment may further include: third party code submitted by a developer to be run within the hosting environment is received, and the third party code is deployed in the sandbox environment.
With continued reference to FIG. 3, one application scenario of a method for running third party code in a sandbox environment in accordance with the present application is shown. In the application scenario 300 of fig. 3, a light-like application "XX buggy" 301 (i.e., third party code) is deployed in a sandbox environment, and a host application "X letter" 303 runs in the host environment. The sandbox environment and the hosted environment are deployed on a first server and a second server, respectively, that are physically isolated from each other. The virtual interface 302 in the sandbox environment enables invocation of an isolated operation type interface (e.g., an interface to obtain buddy information) in the hosting environment. When detecting that the light-like application 301 calls the virtual interface 302 for obtaining the friend information, the first server obtains an identifier of the virtual interface 302. And then, sending a calling request to a second server to call the target interface corresponding to the identifier. Then, a call result (e.g., friend information) returned by the second server is received after a corresponding target interface (i.e., a real interface for obtaining friend information) in the host environment is called. Finally, the call result is returned to the light-like application 301.
According to the method for running the third party code in the sandbox environment provided by the embodiment of the application, the identifier of the virtual interface is obtained when the third party code is detected to call the virtual interface of the isolation operation type in the sandbox environment during running, then the request for calling the target interface corresponding to the identifier is sent to the second server deploying the host environment, and finally the calling result returned by the second server is received, so that the safety of the third party code can be effectively controlled.
With further reference to FIG. 4, a flow 400 of another embodiment of a method for running third party code in a sandbox environment in accordance with the present application is shown. The method for running third party code in a sandbox environment may comprise the steps of:
In this embodiment, the sandboxed environment may be deployed on a first server (e.g., first server 101 of fig. 1) and the hosted environment may be deployed on a second server (e.g., second server 103 of fig. 1). An executing agent (e.g., the second server 103 of fig. 1) of a method for running third party code in a sandbox environment may receive a call request sent by a first server. Wherein the invocation request includes an identification of the virtual interface. The identification may be an identification of the virtual interface that the first server obtained upon detecting a virtual interface of the isolation operation type in the sandbox environment that the third party code invoked at runtime. Here, the first server is physically isolated from the second server, and the third party code may be code provided by the non-hosted environment (e.g., light-like applications).
In this embodiment, the executing entity may determine a target interface (for example, an interface for acquiring friend information) in the host environment corresponding to the identifier received in step 401. Here, the target interface corresponding to the identification of the virtual interface may be, for example, the same target interface as the identification of the virtual interface.
In this embodiment, the executing agent may invoke the target interface determined in step 402, and then return an obtained invoking result (for example, friend information) to the first server, and further return the invoking result to the third party code, thereby implementing an interface invoking process of the third party code.
Compared with the method for directly running the third party code in the host environment, the method for running the third party code in the sandbox environment provided by the embodiment can effectively isolate the running environment of the third party code from the host environment, so that the host environment is prevented from being influenced when the third party code calls the interface.
In some optional implementations of this embodiment, the second server may correspond to a plurality of first servers. That is, one host environment may correspond to multiple sandbox environments. That is, the second server may receive invocation requests of the plurality of first servers. Corresponding to the implementation, the method for running third party code in a sandbox environment may further comprise: and an asynchronous mechanism is adopted to process the received call requests, so that the call requests can not be blocked mutually.
In some optional implementations of this embodiment, the hosting environment may also be deployed on other second servers (e.g., a second server other than the currently executing agent). Corresponding to the implementation, the method for running third party code in a sandbox environment may further comprise: in response to receiving more than a preset number of computationally intensive invocation requests (e.g., invocation requests to be trained online for the machine learning model) within a preset time period (e.g., 1 s), forwarding a portion of the received invocation requests to other second servers. The host environment is deployed on the plurality of second servers, and when a certain second server frequently receives the calculation-intensive tasks in a short time period, the tasks are forwarded to other second servers, so that the request pressure can be uniformly shared, and the correct request time sequence of the sandbox environment is guaranteed.
According to the method for running the third-party code in the sandbox environment, the calling request sent by the first server deploying the sandbox environment is received, then the target interface corresponding to the identifier in the calling request is determined in the host environment, finally the target interface is called, and the obtained calling result is returned to the first server, so that the safety of the third-party code can be effectively controlled.
With further reference to fig. 5, as an implementation of the method shown in fig. 2, the present application provides an embodiment of an apparatus for running third-party code in a sandbox environment, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2, and the apparatus is specifically applicable in a first server deploying the sandbox environment.

In this embodiment, the sandboxed environment may be deployed on a first server (e.g., first server 101 of fig. 1) and the hosted environment may be deployed on a second server (e.g., second server 103 of fig. 1). The identifier obtaining unit 501 of the apparatus 500 for running third party code in a sandbox environment may detect whether the third party code calls a virtual interface of an isolated operation type in the sandbox environment during running, and obtain the identifier of the virtual interface when detecting that the third party code calls the virtual interface. Here, the third party code may be code provided by a non-hosted environment (e.g., a light-like application). The first server is physically isolated from the second server. For example, when virtualization technology is used to virtualize a physical host into multiple virtual hosts, the first server and the second server may be located on different physical hosts.
In some optional implementations of this embodiment, the virtual interface and the corresponding target interface have the same calling mode. For example, the virtual interface and the corresponding target interface have the same call path, call parameter, and the like, but do not have the function of the target interface. The role of the virtual interface is to let the third party code think that it really called the target interface. Generally speaking, since the third party code does not sense whether the third party code runs in the host environment or the sandbox environment, the third party code calls the target interface in the host environment, and actually calls the virtual interface in the sandbox environment, so that the third party code is prevented from bringing potential safety hazards to the host environment.
In some optional implementation manners of this embodiment, the identification obtaining unit 501 may be further configured to obtain a calling parameter of the virtual interface in response to detecting that the third party code calls the virtual interface of the isolation operation type in the sandbox environment at runtime. The implementation may be applicable to virtual interfaces that require parameters to be passed.
In this embodiment, the request sending unit 502 may send a call request to the second server, so that the second server determines a target interface in the hosting environment corresponding to the identifier acquired by the identifier acquiring unit 501, and calls the target interface.
In this embodiment, the result receiving unit 503 may receive a calling result obtained after the target interface corresponding to the identifier is called and returned by the second server (and return the received calling result to the third party code, thereby completing the interface calling process of the third party code).
Compared with the method for directly running the third party code in the host environment, the method for running the third party code in the sandbox environment provided by the embodiment can effectively isolate the running environment of the third party code from the host environment, so that the host environment is prevented from being influenced when the third party code calls the interface.
In some optional implementations of this embodiment, the apparatus 500 may further include a retransmission unit. The resending unit is configured to resend the calling request to the second server in response to not receiving the calling result within the preset time period.
Optionally, different timeout times may be set for different interfaces, so that it is possible to avoid that a third-party developer sets an error for an interface return time to send a call request multiple times.
In some optional implementations of this embodiment, the apparatus 500 may further include an interface calling unit. The interface calling unit is configured to directly call a target interface of a non-isolated operation type in response to detecting that third party code calls the target interface of the non-isolated operation type in the sandbox environment at runtime. Here, the target interface of the non-isolated operation type may refer to an interface that confirms that it does not have an influence on the host environment.
In some optional implementations of this embodiment, the apparatus 500 may further include a code deployment unit. The code deployment unit is configured to receive third-party code submitted by a developer and to be operated in the host environment, and deploy the third-party code in the sandbox environment.
The apparatus for running the third party code in the sandbox environment according to the foregoing embodiment of the present application obtains the identifier of the virtual interface when detecting that the third party code calls the virtual interface of the isolated operation type in the sandbox environment during running, then sends a request for calling the target interface corresponding to the identifier to the second server deploying the host environment, and finally receives a call result returned by the second server, thereby being capable of effectively controlling the security of the third party code.
With further reference to fig. 6, as an implementation of the method shown in fig. 4, the present application provides another embodiment of an apparatus for running third party code in a sandbox environment, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 4, and the apparatus may be applied to a second server deploying a hosting environment.
As shown in fig. 6, the apparatus 600 for running third party code in a sandbox environment of the present embodiment includes a request receiving unit 601, an interface determining unit 602, and a call returning unit 603. Wherein the request receiving unit 601 is configured to receive a call request sent by a first server deploying the sandbox environment, the call request including an identification of a virtual interface of an isolation operation type in the sandbox environment that is called by third-party code at runtime, the first server being physically isolated from a second server deploying the host environment; the interface determination unit 602 is configured to determine a target interface corresponding to the identification; and the call returning unit 603 is configured to call the determined target interface and return the resulting call result to the first server.
In this embodiment, the sandboxed environment may be deployed on a first server (e.g., first server 101 of fig. 1) and the hosted environment may be deployed on a second server (e.g., second server 103 of fig. 1). The request receiving unit 601 of the apparatus 600 for running the third party code in the sandbox environment may receive the call request sent by the first server. Wherein the call request includes an identification of the virtual interface. The identification may be an identification of the virtual interface that the first server obtained upon detecting a virtual interface of the isolation operation type in the sandbox environment that the third party code invoked at runtime. Here, the first server is physically isolated from the second server, and the third party code may be code provided by the non-hosted environment (e.g., light-like applications).
In this embodiment, the interface determining unit 602 may determine a target interface (e.g., an interface for acquiring friend information) in the host environment corresponding to the identifier received by the request receiving unit 601. Here, the target interface corresponding to the identification of the virtual interface may be, for example, the same target interface as the identification of the virtual interface.
In this embodiment, the call returning unit 603 may call the target interface determined by the interface determining unit 602, and then return the obtained call result (for example, the friend information) to the first server, and further return the call result to the third party code, thereby implementing the interface call process of the third party code.
Compared with the method for directly running the third party code in the host environment, the method for running the third party code in the sandbox environment provided by the embodiment can effectively isolate the running environment of the third party code from the host environment, so that the host environment can be prevented from being influenced when the third party code calls the interface.
In some optional implementations of this embodiment, the second server may correspond to a plurality of first servers. That is, one host environment may correspond to multiple sandbox environments. That is, the second server may receive invocation requests of the plurality of first servers. Corresponding to this implementation, the apparatus 600 for running third party code in a sandbox environment may also include an asynchronous processing unit. The asynchronous processing unit is configured to process the received call requests by adopting an asynchronous mechanism, so that the call requests can not be blocked mutually.
In some optional implementations of this embodiment, the hosted environment may also be deployed on other second servers (e.g., a second server other than the currently executing principal). Corresponding to this implementation, the apparatus 600 for running third party code in a sandbox environment may also include a request forwarding unit. Wherein the request forwarding unit is configured to forward part of the received invocation requests to other servers of the deployment host environment in response to receiving more than a preset number of computationally intensive invocation requests (e.g., invocation requests to be trained online on the machine learning model) within a preset time period (e.g., 1 s). The host environment is deployed on the plurality of second servers, and when a certain second server frequently receives the calculation-intensive tasks in a short time period, the tasks are forwarded to other second servers, so that the request pressure can be uniformly shared, and the correct request time sequence of the sandbox environment is guaranteed.
The apparatus for running the third party code in the sandbox environment according to the foregoing embodiment of the present application receives the call request sent by the first server deploying the sandbox environment, then determines the target interface corresponding to the identifier in the call request in the host environment, and finally calls the target interface and returns the obtained call result to the first server, so that the security of the third party code can be effectively controlled.
