[0003] FIG. 6 shows a structural schematic diagram of an electronic device suitable for implementing embodiments of the present disclosure; FIG. 7 shows a structural schematic diagram of a storage medium suitable for implementing embodiments of the present disclosure. In the following, the technical solutions provided in the present specification are described in further detail in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely used to explain the related application, but not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other. In the description of the implementation manner of the present disclosure, the term "comprises" and similar terms should be understood as open inclusion, i.e. "comprises but is not limited to". The term "based on" should be understood as "at least partially based on". The term "one implementation" or "the implementation" should be understood as "at least one implementation". The term "some implementations" should be understood as "at least some implementations". The following may also include other explicit and implicit definitions. In many scenarios of application running, it is desired to obtain the data amount of data transmitted or received by the application through the network (or referred to as the data flow of the application, or simply referred to as the application flow) in the process of application running. The existing scheme for counting the data flow of the application usually obtains the data amount transmitted or received by the application through the interface provided by the network layer of the terminal system, for example, when the application is running. FIG. 1 shows a schematic diagram of an application flow counting scheme. As shown in the example of FIG. 1, the application can obtain the data amount transmitted or received by the application by calling the interface provided by the network layer of the native terminal system in the running process. However, this scheme has the following problems, only the statistical value of the data amount transmitted or received by the entire application can be obtained. Another application flow counting scheme mainly obtains the data amount transmitted or received by the application through a specific network request framework when the application calls the specific network request framework for network data transmission. FIG. 2 shows a schematic diagram of another application flow counting scheme. As shown in FIG. 2, when the application calls the specific network framework, the data amount transmitted or received by the application through the network can be counted by the specific network request framework above the network application layer. However, this scheme can usually only calculate the data amount transmitted or received by the code of the application itself. Therefore, the problem of flow counting omission often exists. In order to solve the above technical problems, the present disclosure provides a data amount determination method. Socket refers to an abstract component corresponding to a communication endpoint for bidirectional communication between applications on different hosts in a network.By calling a socket, a software application above an application layer can exchange data by using a network protocol. Between existing software applications, network communication is usually performed by sockets, even if the network request framework or the third-party SDK is usually performed by calling a socket to send and receive network data. However, the function (or method) for sending or receiving data included in the existing socket can usually only perform the operation of sending or receiving data, and cannot count the amount of data sent or received through the socket. FIG. 3 shows a schematic diagram of a method for determining the amount of data according to an embodiment of the present disclosure. As shown in the example of FIG. 3, the instance member in the currently running socket object can be obtained by reflection, and then a proxy object corresponding to the instance member is constructed. The sending data function and the receiving data function of the proxy object can be constructed based on the sending data function and the receiving data function of the instance member and the data amount counting code. The sending data function and the receiving data function of the proxy object can be used not only for sending or receiving data, but also for counting the amount of data received or sent through them. Then, the instance member in the socket object can be replaced by the proxy object (or proxy member), so that the data transmitted (including sent and received) through the socket object can be directly counted. In some embodiments, the data amount counting code can also be used to determine the data flow of the application for different access domain names, or the data flow of the application for different access addresses. The advantage of this method is that, on the one hand, compared with the traditional scheme for counting the application flow of the specific network request framework, not only the data flow of the network accessed by the application itself code can be counted, but also the data flow of the network accessed by the third-party SDK called by the application can be counted, thereby solving the problem of missing flow statistics. On the other hand, compared with the traditional scheme for counting the application flow through the network layer interface, more detailed data flow statistics values can be obtained, for example, the data flow statistics values for different access domain names or different access addresses can be obtained. The detailed process of this method is further described below.

[0004] S 4 illustrates a flowchart of a method for determining data volume according to an embodiment of the present disclosure. As shown in FIG. 4, the method comprises at least the following steps: in step S401, obtaining an instance member in a target socket object in running through reflection, constructing a proxy object corresponding to the instance member, a data transmission function of the proxy object comprising a transmission part and a data volume determination part, the transmission part transmitting data by calling a data transmission function of the instance member, and the data volume determination part being configured to determine data volume of data transmitted by the transmission part; and in step S403, replacing the instance member in the target socket object with the proxy object, so as to transmit data through the data transmission function of the proxy object and determine data volume of the transmitted data. First, in step S401, an instance member in a target socket object in running is obtained through reflection, and a proxy object corresponding to the instance member is constructed. The data transmission function of the proxy object can comprise a transmission part and a data volume determination part, the transmission part can transmit data by calling a data transmission function of the instance member, and the data volume determination part can be configured to determine data volume of data transmitted by the transmission part. In this step, the instance member in the target socket object in running can be obtained through reflection, and the proxy object of the instance member is constructed. The instance member (which can be identified as impl in an example) is an instance (instance) that actually implements the function of transmitting data of the socket in the socket object, or in other words, transmitting data through the socket object essentially involves calling the instance member of the socket object to transmit data. Reflection is a technology for interacting with classes or objects at runtime. Through reflection, object data and object instances can be obtained dynamically at runtime, such as obtaining data members (variables or properties) and member functions (methods) of an object, including obtaining hidden members of the object. The hidden members of the object usually refer to the members in the object that are not directly exposed to external access. Since the instance member in the target socket object in a production scenario can be a hidden member, it is difficult to access directly when calling the target socket object. Therefore, the hidden member of the target socket object can be obtained through reflection at runtime. In an embodiment, the instance member in the target socket object in running can be obtained through reflection when the target socket object is initialized. The initialization of the object usually refers to the process of allocating memory for the object and setting its initial state or value, which is also the first state of the object in running. In this way, the data volume of data transmitted through the target socket object can be more completely counted. In an embodiment, the target socket object can be a socket object called by a target application.In different embodiments, the target application can be a software application for different specific businesses or purposes, which is not limited in the present specification. The data transmission function of the proxy object can be obtained by combining the data transmission function of the instance member and the data volume statistical code. Specifically, the data transmission function of the instance member can include a data sending function and a data receiving function for data sending and data receiving, respectively. Therefore, in one embodiment, the data transmission function of the instance member can include a first data sending function and a first data receiving function, and the data transmission function of the proxy object can include a second data sending function and a second data receiving function. Further, the second data sending function can include a first transmission part and a first data volume determination part, the first transmission part can transmit data by calling the first data sending function, and the first data volume determination part can be used to determine the data volume of the data transmitted by the first transmission part; the second data receiving function can include a second transmission part and a second data volume determination part, the second transmission part can receive data by calling the first data receiving function, and the second data volume determination part can be used to determine the data volume of the data transmitted by the second transmission part. In one specific embodiment, the data sending function of the proxy object (the second data sending function) can be obtained by combining the calling of the data sending function of the instance member (the first transmission part) and the data volume statistical code (the first data volume determination part); and the data receiving function of the proxy object (the second data receiving function) can be obtained by combining the calling of the data receiving function of the instance member (the second transmission part) and the data volume statistical code (the second data volume determination part). In this way, not only can data be sent and received through the proxy object, but also the data volume sent and received through the proxy object can be completely counted. The data volume determination part can not only determine the total data volume sent or received through the data transmission function, but also determine the data volume sent or received according to the access address or access domain name. Therefore, in one embodiment, the data volume determination part can be used to determine the data volume of the data transmitted by the transmission part according to the access domain name. In another embodiment, it can also be used to determine the data volume of the data transmitted by the transmission part according to the access address. In one specific embodiment, one or more of the total data volume transmitted by the data transmission function of the proxy object, the data volume determined according to the access domain name, and the data volume determined according to the access address can be output, for example, through the return value or output parameter of the data transmission function. In this way, further refined statistical values of the data volume of the application accessing the network can be obtained based on a finer granularity relative to the entire application.For example, not only the total data amount transmitted and / or received by the application can be obtained, but also the data amount transmitted and / or received by the application for different access addresses or different access domain names can be obtained. Then, in step S403, the instance member in the target socket object is replaced by the proxy object, for transmitting data through the data transmission function of the proxy object, and determining the data amount of the transmitted data. In this step, the instance member in the target socket object can be replaced by the proxy object, so that data can be substantially transmitted through the data transmission function of the proxy object, and the transmitted data amount can be determined. In different embodiments, the specific manner in which the instance member in the target socket object is replaced by the proxy object can be different, which is not limited in the present specification. As described above, in the production scenario, the instance member in the target socket object can be a hidden member, which is difficult to directly replace. The instance member can be indirectly replaced by setting other non-hidden members of the target socket object. Specifically, in an embodiment, a factory object for generating the proxy object can be constructed; a global factory member of the socket class for generating the instance member in the socket object is set to the factory object. In this way, the instance member can be replaced by the proxy object in the case where the instance member is a hidden member. In some scenarios, the third-party SDK called in the application also accesses the network through other socket objects. Since in this scenario, the socket object called by the third-party SDK can generate the instance member thereof through the global factory member of the socket class, in an embodiment, the target socket object can be called by the target application, the target application can also call the third-party software development kit, the third-party software development kit can call other socket objects in addition to the target socket object, and the global factory member can also be used to construct the instance member of the other socket object. Through the above manner, in the scenario where the third-party SDK called in the application accesses the network through the socket object, not only the data flow of the application itself accessing the network can be counted, but also the data flow of the third-party SDK called by the application accessing the network can be counted, solving the problem of missing flow statistics caused by the third-party SDK called by the application accessing the network.
