Method, apparatus, device and storage medium of data acquisition

An electronic device, comprising:

• a memory;
• and
• a processor,
• wherein the memory is used to store one or more computer instructions which, when executed by the processor, cause the processor to perform a method comprising:
• activating a local server proxy in a preset application program;
• in accordance with a determination that the preset application program invokes a preset connection function, acquiring the preset connection function, and replacing a destination address in the preset connection function with a target address corresponding to the local server proxy, to establish a connection between the preset application program and the local server proxy, wherein the preset connection function is a connection function called when the preset application program initiates a network request, the destination address is an address of a remote server with which the preset application program needs to establish a network connection, and the target address is pre-written in the preset application program;
• establishing a connection between the local server proxy and a real server corresponding to the target address based on connection information received from the preset application program via the local server proxy;
• and
• acquiring data during a procedure of data forwarding between the real server and the preset application program via the local server proxy,
• wherein the method further comprises:
• before determining that the preset application program invokes the preset connection function,
• loading a first core library into the preset application program, wherein the first core library performs centralized management of the invoking of a preset socket by injecting a proxy connection function in the first core library into a second core library, the second core library contains a preset connection function for establishing a connection to the preset socket and
• injecting a self-defined connection function into the second core library based on a preset injection approach corresponding to the proxy connection function,
• wherein replacing the destination address with the target address comprises:
• in accordance with a determination that the preset application program invokes a preset connection function via the second core library, invoking the self-defined connection function instead to replace the destination address of the preset connection function with the target address corresponding to the local server proxy.

A computer program product comprising a non-transitory computer readable storage medium storing one or more computer instructions thereon which are executed by a processor to:

• activate a local server proxy in a preset application program;
• in accordance with a determination that the preset application program invokes a preset connection function, acquire the preset connection function, and replacing a destination address in the preset connection function with a target address corresponding to the local server proxy, to establish a connection between the preset application program and the local server proxy, wherein the preset connection function is a connection function called when the preset application program initiates a network request, the destination address is an address of a remote server with which the preset application program needs to establish a network connection, and the target address is pre-written in the preset application program;
• establish a connection between the local server proxy and a real server corresponding to the target address based on connection information received from the preset application program via the local server proxy;
• and
• acquire data during a procedure of data forwarding between the real server and the preset application program via the local server proxy,
• wherein the method further comprises:
• before determining that the preset application program invokes the preset connection function,
• loading a first core library into the preset application program, wherein the first core library performs centralized management of the invoking of a preset socket by injecting a proxy connection function in the first core library into a second core library, the second core library contains a preset connection function for establishing a connection to the preset socket and
• injecting a self-defined connection function into the second core library based on a preset injection approach corresponding to the proxy connection function,
• wherein replacing the destination address with the target address comprises:
• in accordance with a determination that the preset application program invokes a preset connection function via the second core library, invoking the self-defined connection function instead to replace the destination address of the preset connection function with the target address corresponding to the local server proxy.
